た。[Prior Art] In recent years, automobile interior materials have become lighter, moldable, and
Polypropylene resin has been widely adopted due to cost reduction. Conventionally, molded bodies of ABS or polypropylene resin have been used as parts for automobile interior materials, but as automobiles become more sophisticated, aesthetically pleasing, and designed, the number of cases in which the surfaces of these materials are electrostatically flocked is increasing. As you know,
Since non-polar polypropylene is difficult to adhere to, research has been conducted not only in adhesives for electrostatic flocking but also in adhesives for polyolefins in order to impart adhesion or adhesion to polypropylene.

Or its anhydride has been modified by grafting, but it is incomplete in terms of adhesion, and the current situation is that the surface is usually treated with a primer, which has led to improvements in quality. On the other hand, as for problems with adhesives, the two-component mixture type consisting of a base agent and a curing agent has problems such as workability, mixing errors, and restrictions on pot life after the two-component composition. Furthermore, in the case of solvent-based adhesives, there is an extremely high risk of environmental pollution, adverse effects on the human body, fire, explosion, etc. due to organic solvents. As a way to solve this problem, the development of one-component aqueous emulsions is underway, but all proposals use expensive chlorinated polypropylene or a diluted solution of chlorinated modified polypropylene in an organic solvent, Since it requires processes such as emulsification and further solvent removal, it becomes an extremely expensive adhesive and lacks industrial practicality.

It has sufficient performance to withstand the use of automobile interior materials, and because it is a water-based emulsion type, it is superior in terms of risks such as environmental pollution, adverse effects on the human body, fire, explosion, etc., and is also practical in terms of price. Its value is extremely high and its significance is great.
