おく必要があった。Prior Art and Problems to be Solved Among various rubber-based adhesives, chloroprene-based adhesives based on chloroprene rubber are generally used in a wide range of applications, such as the production of door trims on automobile assembly lines ( This is used.The door trims are AB
S414 resin or plastic composite material i (for example, polypropylene mixed with Nihonmatsu or old paper, polypropylene hardened with wood chips, wood, or fibers) is used as the core material, and a skin material (for example, surface decoration polyester) is used as the core material. It can be obtained by adhering (polyolefin foam laminated with vinyl chloride sheet or film, foamed polyvinyl chloride skin layer, polyurethane foam laminated with polyvinyl chloride or woven fabric) by vacuum forming or press forming. Recently, a two-component solvent-based chloroprene adhesive consisting of chloroprene rubber, a tackifier resin, an organic solvent as main ingredients, and an incyanate curing agent has been used for this adhesive. However, although it is somewhat effective in terms of spray workability and initial adhesive strength, for example, when the skin material is the above-mentioned polyolefin foam, the polarity of the foam is low, so it is difficult to obtain sufficiently satisfactory adhesive properties. figure,
In particular, heat resistance is poor, and strength and creep resistance under high-temperature loads are weakened. For this reason, it was necessary to apply adhesive to both surfaces of the adherend (core material and skin material), and it was also necessary to perform primer treatment or plasma irradiation on one side of the adherend in advance. .

に至った。Therefore, the present inventors have developed a wave-shaped chloroprene-based adhesive that does not require pre-treatment such as primer treatment and exhibits sufficient adhesion and heat resistance when applied on one side even when bonding such polyolefin foams. As a result of intensive research in order to provide adhesives, we found that by specifying the types (or characteristics) of chloroprene rubber, tackifying resins, and incyanate hardeners, as well as the rubber/resin compounding ratio, it is possible to create adhesives for the desired purpose. The present inventors have discovered that the present invention can be obtained, and have completed the present invention.

If the amount is less than 20 parts, the adhesiveness during lamination will be poor and the one-sidedness will be reduced, and if it exceeds 50 parts, the polarity of the adhesive will increase and the adhesiveness with the polyolefin foam will decrease.
