What kind of glue to stick paper to plastic. Types of glue

When modeling and making various crafts, it is often necessary to quickly and reliably glue cardboard parts or glue cardboard to other materials - fabric, wood, foam, cork, metal, etc.

Unlike thin paper, cardboard is a more rigid and dense material, so ordinary stationery (silicate) glue cannot do this task, especially if we are talking about gluing large parts.

• PVA is a classic adhesive based on an aqueous dispersion of polyvinyl acetate. This composition is successfully used for gluing various porous materials - paper, cardboard, wood, fiberboard, MDF, fabric, etc. To date, PVA remains the most popular adhesive in cardboard modeling.

Suitable for bonding almost all natural materials.

On sale you can find several varieties of this glue: stationery, household, universal and construction.

Choosing PVA glue for cardboard, we recommend paying attention to the universal PVA glue, the so-called PVA-MB. It is not as liquid as stationery, and not as rough as construction, which is used for gluing linoleum and carpet.

It is most profitable to buy universal PVA glue in hardware stores, where it is usually sold in large packages (500 gr, 1 kg, etc.). As for the shortcomings, PVA glue has only one - after drying, the parts to be glued warp a little.

• Moment Joiner Express- modern adhesive from Henkel. Designed specifically for working with wood, plywood, veneer, fiberboard, MDF, cardboard and other natural materials.

Its composition resembles PVA glue, but it is improved with special additives that improve the adhesion of the composition, make it more elastic when dried. glue corrugated cardboard this glue is very convenient, because the glue line sets quickly, eliminating the slipping of the glued parts.

Moment Stolyar Express after drying becomes colorless, which is important when modeling - the glue will not be noticeable in the seams between the parts to be glued.

• Modeling adhesive UHU Holzleim Express- fast-setting glue for a tree, possesses surprisingly high gluing ability.

Specially designed by UHU specialists for modeling, housework, repair wooden furniture etc. Designed for gluing any wood and wood-like materials in any combination.

Ideal for bonding cardboard and paper, also suitable for bonding cardboard to cardboard.

It is indispensable when fast setting of the glued surfaces is required. After drying, it becomes transparent, resistant to moisture.

• Moment Universal Gel- modern waterproof and frost-resistant express adhesive in the form of a gel, which does not spread or drip.

Retains elasticity after drying, does not warp or deform the glued parts.

Moment Universal Gel is widely used in modeling and creativity, when it is necessary to quickly and reliably glue wood, ceramics, PVC, rubber, cork, fabrics and other materials.

Ideal for gluing paper, cardboard and corrugated cardboard, incl. inclined surfaces and large surfaces.

• "505" Universal second glue- liquid transparent gluing structure, on a consistence close to water. Designed for bonding metal, rubber, leather, ceramics, paper, cardboard, wood, plastic, etc.

Indispensable when instant fixation is required small parts from paper and cardboard when modeling.

Paper (cardboard) modeling is one of the most accessible types technical creativity, however, when working with cardboard and glue, certain nuances should be taken into account.

In particular, extreme care must be taken when working with adhesives on water based, because when dried, the water "pulls" the material, and the product begins to deform.

To prevent the paper from warping during drying, the glue must be applied in a thin, even layer on one of the surfaces to be glued. After that, the parts are connected and ironed so that air bubbles do not form under them.

No need to try to assemble the model quickly, this should be done in stages, only after the frame has completely dried.

When working with Moment glue, precautions should be taken, since it is based on solvents. It is not recommended to inhale its vapors, since they are toxic, after gluing the product should be left to dry in a ventilated area.

You will definitely take this trick into service if you did not know it before. It will be about how to very reliably glue plastic or plastic parts with ordinary instant glue, using one small secret, which increases the strength of the connection of two parts by more than 10 times.

What is the trick?

So, the secret is that around the seam of the parts to be glued, we will apply ordinary soda with superglue. The result is a strong thickening around the seam.
The fact is that cyanoacrylates, which make up the glue, interact with soda. They interact, and are not the usual filler. When these two components are mixed, an instant reaction occurs and the strongest composition is obtained, with which it is quite possible to glue not only plastics, but also metals. Peculiar similarity cold welding. Secondary adhesive alone does not have half the strength if used alone. No wonder everyone did poorly and fell apart. But with the use of this technology, this will no longer be the case.

It will take

• Any super or second glue.
• Baking soda.

We glue plastic

Let's get started. I broke off the bushing into which the screw is screwed. And, accordingly, I will now restore all this.
At the beginning, everything is as usual. Lubricate the place with glue.

At one and at the second detail.

Let's connect them.

Now the soda comes into play. When the parts come into contact, excess glue is squeezed out, it must be sprinkled with plenty of soda.

After 5 seconds, the excess can be blown off.

Then pour plenty of superglue around the crack and then again fill it with soda.

We blow off the excess again.

We repeat the process one more time.

Sprinkle generously.

As a result, a strong influx formed around the sleeve, which will securely hold everything.

Although everything has hardened before our eyes, it is recommended to let it stand for about 24 hours before using the product.

Pros and cons of the method

Pros:

• Instant curing. Even large drops freeze immediately.
• A very durable monolith is obtained as a result.
• Sticks to almost any plastic.
• You can even seal holes and holes.

Minuses:

• Instant curing can act as a negative factor, due to the fact that the composition cannot be poured into the center of the parts to be glued.
• The reaction occurs with the release of heat, which in some cases can serve as a negative.
• Unfortunately, such a composition can only be applied to the surface, but there are times when it is not possible to get there.

I especially recommend that motorists take note of this recipe, since I myself have glued dashboards and glass filters in this way more than once. Hold tight!

Dear friends, I again have a question for the audience, "because you know everything." It's not that I can't glue paper. :-) But progress is moving forward, the market is littered with a million varieties of glue, and the task is serious.
Imagine a postcard like this:

Paper - 300g. It has a glossy plotter print. those. the surface is quite smooth. And this postcard, ideally, will be opened and closed several times in a lifetime, i.e. they will move it, and I would like it not to fall apart from this.

In this postcard, I specially designed everything so that the ride would stick large planes. But when somewhere you need to glue a very small "tuck" (and the gluing plane is some 5 mm, and at the same time there is some tension, and this place will be subjected to some kind of load), this falls apart even more readily.

I have children's books, so voluminous, which will soon be 30 years old. And they still have not fallen apart (not counting those places that were simply torn off by the children with their hands). What were they glued to?

For me, by far the most reliable glue is the good old PVA. If it dries up and grabs, it holds tightly. But he has two drawbacks: if you smear them with a more or less noticeable plane, he can give waves. And it also releases quite a lot of moisture when it dries. Sometimes you put something freshly glued under the press or in a frame, and a couple of days later it comes out - wet! Those. you can’t just glue it and give it away - you have to dry it. Well, that's fine. I am mostly confused by waves in PVA.

And everyone else ... There is a so-called " hot gun"with such plastic tubes that melt and glue them. It supposedly holds well. But the layer turns out to be too thick, and it also falls off.
There are all sorts of such sticks, they are often praised. But I don't trust them either. After a while, everything glued together safely falls apart.

Still, of course, it would be nice if the glue did not get dirty too much. That's what PVA is good for - it becomes transparent after drying.

Many praise rubber glue. But he first sometimes unexpectedly gives greasy spots. And secondly, over time, it also weathers and evaporates.

There is also a normal such paste, which seems to be boiled from starch. Here's one:
http://www.manufactum.de/papierkleber-coccoina-p752391/
But he didn't convince me either.

Accordingly, the question is: what is the best glue for paper? To keep well. Even if the bonding area is small, but there is some load? And so that there is not much dirt from him (and all sorts of greasy spots). And so that the paper, all wet, does not worry. And for a long time. So that in a year or five it will also hold on.

Well, or maybe just someone knows how in industrial production (in printing houses?) Bulky books and bulky postcards are glued together?

Plastic products are widely used in everyday life. In case of breakage, you need to know what kind of plastic glue you need for repair. In order for the gluing result to be durable and safe, we advise you to take a closer look at the types of plastic and the rules for selecting an adhesive composition.

What does the marking on plastic mean?

Since some adhesives may not hold together, but dissolve plastic, it is recommended that you study the markings on the broken product. The plastic type icon looks like a triangle made up of arrows (symbol of recycling). Inside it there are numbers from 1 to 7, and below there is an inscription. According to these identification marks, the belonging of the material to one or another type of plastic is determined, which will allow you to choose the right glue.

What types of plastic exist:

• 1 (PET) - stands for polyethylene terephthalate. It is used to produce food packaging for liquid products.
• 2 (HDPE) - high density polyethylene, designed for the production of packaging and shrink film.
• 3 (PVC) - polyvinyl chloride, better known as PVC. It is made from plastic windows, linoleum, etc.
• 4 (LDPE) - low density polyethylene, toys for children, pipes, bottles, packaging containers are made from it.
• 5 (PP) - polypropylene, heat-resistant material. It is used for the production of food packaging, medical disposable instruments, household appliances, pipes, thermal dishes.
• 6 (PS) - polystyrene. They make disposable tableware. Expanded polystyrene is widely used in construction.
• 7 (O) - this type of plastic is not recyclable, consists of a mixture of polymers, paper, foil.

Glue marking

The main difficulty is that the labeling of the adhesive does not match the symbols for plastic recycling.

How is plastic adhesive labeled?:

• PE - polyethylene;
• PC - polycarbonate;
• PP - polypropylene;
• PVC - polyvinyl chloride;
• PMMA - organic glass;
• PUR - polyurethane;
• PA 66 - polyamide.

Sometimes it's easier to find clear instructions in Russian than the marking icon. But if there are no recommendations on the package, then the designations will help you make the right choice.

Types of glue

Plastic is characterized by low adhesion due to its smoothness, therefore it is more difficult to glue it than other materials. In industry, such products are fastened by welding. At home, this method is not used, but you can pick up a good glue. The principle of operation of the composition is as follows: it dissolves the surface, and with strong squeezing, the parts are connected. Therefore, the main component of adhesive for plastic is a solvent for synthetic polymers. For viscosity, the composition contains liquid polystyrene.

Liquid glue for plastic and Moment plastic

The group of adhesives for plastics can be divided into the following types:

1. hot glue. Represents solid glue sticks. They must be warmed up before use. There are special ones, there are also types of glue for use without a gun. Such a composition is suitable for small jobs, as it does not have a special bond strength.
2. Contact. It is often sold complete with a hardener, which must be mixed with the bulk in the proportions indicated on the pack. This type of glue can tightly glue plastic, but there is one drawback: the product is toxic. Need to use resources personal protection. For a better bonding of the parts after applying the glue, you need to wait 10 minutes, and only then squeeze them firmly.
3. is water-based and is considered the least effective way fastenings. It dries for a long time (at least a day). It is used to repair small items that are not subjected to increased loads. But liquid glue samples do not deform the plastic, which is very important when working with small parts.
4. Reactionary- reliable and affordable option glue for plastics. There are several types of such compositions: some are designed to work under water, others harden under the influence of ultraviolet radiation, and others work in the open air. There are one-component and two-component.

Advice! Do not use toxic contact adhesive on children's toys.

Product examples

What can be found on the shelves of construction and hardware stores:

1. « Moment plastic"- a type of glue that connects many types of plastics. He has transparent base, quickly seizes and forms a strong connection. It is waterproof and heat resistant. However, it has toxic substances, and it is not used to repair products that come into contact with food or skin.
2. "Super Moment» - second glue.
3. - epoxy glue, hardens in 20 seconds. Simple and easy to use composition.
4. "" - a brand that offers several types of glue for plastic. Among them, adhesive-sealant for transparent plastic, composition Plus for PVC, PMMA- glue for polystyrene and acrylic surfaces.
5. « Second» - superglue for hard plastics. One of the fastest acting compounds.
6. For minor car repairs, special automotive plastic sealants are sold.
7. Rexant - hot-melt adhesive, produced in the form of rods. It can be transparent or colored (to mask joints if colored parts are connected).
8. Akfix HT300 - heat and water resistant composition. Withstands temperatures up to +300 degrees. This adhesive sealant contains silicone. It reacts to moist air.

This is not the entire range offered by the adhesive industry. This is not to say that some glue is better or worse. Each composition is designed for specific types of work. Read the instructions carefully and follow all recommendations.

How to glue plastic

The type of plastic is installed, the right glue is selected. How to glue plastic objects correctly:

1. Details should be cleaned up. If necessary, the item is degreased with soapy water or ethyl alcohol. A clean surface has more adhesion, and objects will be easier to stick.
2. It doesn't hurt to lightly sand the surfaces to roughen them. So the glue will take better.
3. Two-component formulations are mixed only after surface preparation.
4. If the parts are covered with glue with a brush, then an object with artificial bristles is taken.
5. Glue is applied in such an amount that when compressed, its excess does not come to the surface.
6. Squeeze objects together firmly, but gently.
7. The duration of adherence of materials depends on the selected adhesive.

Advice! Use a needle to glue a thin crack.

Sometimes you need to attach the most various materials: wood, glass or metal. In this case, the adhesive must take into account the characteristics of the two surfaces to be joined, and not just the plastic.

Glue Super Moment

Job Tips with plastic:

1. For outdoor use, waterproof glue is used.
2. In spite of high temperature, which the adhesive can withstand, plastic objects themselves should not be exposed to it.
3. When working with contact adhesive, it is necessary to ventilate the room.
4. The best 7(O) marking adhesive is epoxy. This type is also suitable for polystyrene.
5. If there is no marking on the product, then start from this: for plastic toys and artificial glass is taken mainly polystyrene; for bottles, buckets and boxes, glue designed for polypropylene and polyethylene is suitable.

Don't be afraid to read the label plastic products and glue. If the repair of small Lego-type toys is a simple process, then the Sekunda glue familiar to everyone may not be suitable for more serious work.

Friends, all good mood! As usual, the topic of this article will also deal with computer topics, but from a slightly different angle. Let's talk about what glue plastic to plastic tightly.

This life hack was found by me on the Internet and put into practice even at sub-zero temperatures. The person I learned about this method from originally used it to glue laptop cases around the screen hinges. Believe me, this is a very busy part. And the plastic there is such that not a single super glue takes it at all.

But the matter is fundamentally changed by ordinary edible salt. Yes, yes, friends, you just need to do explosive mixture from super glue and salt. You can, of course, try soda, but after looking at the tests, I came to the conclusion that salt is still better:

So, let's start gluing the plastic tightly. Let's just show this with an example. car bumper, which initially tried to glue different types glues, but everything was useless.

First, the damaged area must be shed degreaser. It is clear that due to the specifics of the crack, it did not work out perfectly. But nevertheless, as it is. Next, a pinch of fine salt was taken, which was abundantly sprinkled on the "wound":

After that, we use ordinary super glue. Before that, by the way, he did not glue the plastic of this bumper at all. Tried this and that, no result:

But after applying this life hack, the situation has changed radically. Even despite the fact that the gluing process took place at a temperature of -2, the plastic finally stuck together tightly. Of course, visually the "fault" remained visible, since a lot of salt was swollen:

In general, friends, this is how things are. If one of you has already tried this method, please write in the comments about the successes and materials that you glued together. That's all for now and see you soon!
