In response to this situation, in order to limit the use of organic solvents that have been used in large quantities in various industries such as adhesives, adhesives, paints, and printing inks, and to make the materials used non-polluting, water-based adhesives, New research is underway in the fields of reactive adhesives and hot melt adhesives. As an example of this, water-based adhesives using emulsion latex have been developed and are widely used in the building materials, interior materials, packaging, automobile industries, etc., as is well known. Furthermore, water-based adhesives using water-soluble polymers are widely used in the packaging industry, wallpaper manufacturing, paper processing industry, and general household use.

On the other hand, the biggest drawback of these water-based adhesives is that they dry slowly, but in view of the above-mentioned advantages, the shift from adhesive systems using organic solvents to water-based adhesive systems can be said to be the trend of the times.

The slow drying time of water-based adhesives compared to solvent-based adhesives is mainly due to the difference in evaporation rate between water and organic solvents, but in the paint industry it is relatively easy to transition from organic solvent-based paints to water-based paints. It is. The reason for this is that in the case of paint, the painted surface is exposed to the atmosphere and water evaporates easily, so slow drying is not a major drawback. This is due to the early onset of the anchoring effect.

On the other hand, in the case of adhesive systems, the purpose is to form an adhesive film between two adherends and simultaneously bond them together to demonstrate their usefulness as a new material. This results in the disadvantage that the water sandwiched between the adherend materials does not easily volatilize. FIG. 1 is illustrated to facilitate understanding of these processes. This drawing shows step-by-step the process by which an adhesive layer forms an adhesive film when bonding materials using an emulsion latex water-based adhesive. is coated with an emulsion latex adhesive and bonded to another adherend material 2, 3 represents rubber or resin particles in the adhesive, and 4 represents water.

As shown in FIG. 1, in the case of a water-based adhesive using emulsion latex, an adhesive film is formed only after water evaporates and particles are fused. In the case of water-soluble adhesives using polymers dissolved in water, such as polyvinyl alcohol, an adhesive film is left after the water evaporates, but in the case of emulsilon or latex, the particles There is a stage called fusion. A practical adhesive mechanism is completed only after the adhesive film is formed.

On the other hand, in the case of paint, a paint film is formed and the purpose is achieved.Similar to the case of adhesives, the stage before the paint film is formed (in this case also If the wettability with respect to the adherend material satisfies practical characteristics (initial adhesion), there is no particular problem.

In the case of adhesives, the role is to adhere another adherend material and provide usefulness as a new material, so in many cases stress is applied between the adherend materials in the north polarity. , it is required to withstand that stress. Therein lies the difficulty of adhesives when compared to paints.

As is clear from the above explanation, the biggest drawback of water-based adhesives using emulsion or latex is poor drying properties due to the slow evaporation rate of water.
As a result, it takes a long time to form an adhesive film, that is, it takes a long time to form the adhesive film. The problem with this drawback is that it cannot withstand practical stresses such as shearing and peeling immediately after adhering to the interface between the adhesive layer and the adherend material.

If only a compressive force is applied to the adhesive layer immediately after adhesion, a continuous film of adhesive is formed, which can sufficiently withstand actual stresses such as shearing and peeling. Using the facts of Party B,
Conventionally, emulsion adhesives have been used in large quantities in industries such as architecture and building materials.

That is, compressive force is applied to the bonded object at room temperature, the object is pressed and cured until a continuous adhesive film is completely formed, and then the pressure is released and the bonded object is used for practical use. Although the time required to form an adhesive film, that is, the film-forming time, can be somewhat shortened by increasing the temperature, there is a limit to the shortening of the pressing time. In the case of emulsion-based adhesives, it is difficult to form a continuous film unless the water completely evaporates.In order to accelerate water evaporation, for example, at high temperatures of 100°C or higher, water boils and forms an adhesive film. Air bubbles may appear. On the other hand, in the case of latex adhesives, it is possible to form a continuous film even if some water remains. In the case of emulsion adhesives, they are usually cured at room temperature for one day or more, and under pressure for at least half a day, but as this increases the total production cost, in many cases they are cured at room temperature after pressing. is the current situation.

On the other hand, in the case of adhesives that use a large amount of organic solvent, even if you apply another adhesive material immediately after applying the adhesive to the adherend material, it will not be sufficient to withstand the actual initial stress. Therefore, in order to convert adhesives that use large amounts of organic solvents into non-polluting water-based adhesives, adhesive strength that can sufficiently withstand the initial practical stress, so-called initial adhesive strength, is an essential condition. No water-based adhesive has been developed that satisfies the adhesive strength, and in that sense it does not meet social demands.However, it is extremely difficult to develop an adhesive that satisfies this demand. This will be clear from the explanation of the adhesive bonding mechanism.

Although we have carried out research on each of the above items, we have found that Method ① increases production costs and is impractical, and Method ③ does not improve the initial adhesion as much as expected, and the final adhesion does not improve as much as expected. (Water resistance, humidity resistance). The auxiliary agents used in method (2) are plasticizers and film-forming auxiliaries, which are usually phthalate ester plasticizers, high boiling point solvents, butyl cellosolve, butyl cellosolve acetate,
Butyl carpitol, butyl carpitol azetate,
Carpitol acetate, hexyl glycol, texanol, etc. have been used, but the rate of water evaporation is still not accelerated and initial adhesion is not improved as expected. Method (2) is based on a special idea discovered by the present inventors at the research stage. The potential on the surface of the colloid is lowered to cause the colloid to condense. The water molecules contained in the emulsion or latex have a slow volatilization rate, but the water layer t! It has been found that if the particles are separated, the rate of evaporation is surprisingly accelerated.

Among these, in view of economic efficiency, it is appropriate to use weakly acidic accelerators such as ammonium sulfate and ammonium nitrate alone or in combination with some quaternary ammonium salts. For example, a two-component adhesive having the above composition is applied onto a non-porous painted steel plate at a rate of 150 to 200 g/
When agent B is evenly sprayed at a coating rate of about 10 g/m2 onto the coated surface of agent A, which has been applied at a coating rate of 10 g/m2, agent A immediately begins to form a film, forming a uniform continuous film.

The time required for the two-component adhesive consisting of Part A and Part B to develop sufficient initial adhesiveness could be shortened to about 1720 hours or less compared to the case of Part A alone. In addition, even when the amount of coating B was increased beyond the specified value, no significant difference was observed in the time required to develop sufficient initial adhesive strength, and on the contrary, there was a tendency for the tackiness of the adhesive film to decrease. When using the water-based adhesive of the present invention, there is no significant difference in the time it takes to develop sufficient initial adhesive strength even if the environmental temperature of the coating operation is low; however, the adhesive strength of the wedge adhesive film increases at high temperatures. We obtained increasing results.

Conventionally, two-component adhesives have been applied by applying them to the adherend material after they have been mixed, since the adhesive's performance can only be achieved by evenly mixing parts A and B, either manually or mechanically. Generally adopted, it had the disadvantage of having to work under unfavorable conditions of limited pot life due to mixing. Furthermore, the properties of the adhesive may change due to mixing, such as an increase in the viscosity of the adhesive or the beginning of hardening, which may impede painting work. When using a coating device, it is necessary to continue dispensing without stopping the device, and the adhesive that is being dispensed outside of the time when it is actually being applied to non-adhesive materials cannot be reused, so it must be carefully disposed of, such as discarding it. There were disadvantages.

Although the water-based adhesive of the present invention satisfies the performance as an adhesive with only agent A as in the previous stage, it is possible to develop initial adhesive strength in a short period of time by adding agent B. The use of agent B also has the advantage of increasing the final adhesive strength as an adhesive. However, since the two-component water-based adhesive used in the present invention has remarkable fast curing properties, it is difficult to apply the adhesive after mixing parts A and B in advance, as with conventional two-part water-based adhesives. cannot be adopted.
