Kある。<Conventional technology and problems> Chloroprene-based Tutex-type adhesives, which are made by mixing chloroprene latex with phenolic resin emulsion in alcohol and metal salts (metal oxides such as zinc white and i-gnesia), are non-polluting. As a universal adhesive, it is applied to both sides of the adherend, dried, and then bonded together, but there are limits to the initial adhesive strength, especially the initial heat resistance.
In addition, the adhesion to polyolefin plastics is poor and '#-0.'On the other hand, acrylic emulsion adhesives made of heavy metal emulsification of monomers mainly composed of 4(meth)acrylic acid esters have poor adhesion to polyolefin plastics (foamed It has excellent adhesion to the body), but the initial adhesion strength, normal adhesive strength, heat resistance,
<Objective of the Invention> The present invention provides a water-dispersed contact adhesive that has excellent initial adhesion strength, heat resistance, and water resistance, and is also capable of adhering to polyolefin plastics, etc., and a method for using the same. It is possible to provide the following.

As mentioned above, a medium to fast crystallization rate (4) is suitable in terms of adhesive strength), and metal salts as vulcanizing agents include aqueous dispersions of magnesia (MgO) and zinc white (ZnO), and adhesives. A resin obtained by chelation reaction with an alkylphenol resin such as ordinary terpene-modified phenol resin or t-butylphenol resin as an imparting agent, and magnesium oxide (MgO), cadmium oxide (CdO), calcium oxide (CaO), etc. as a metal salt, and toluene etc. A tackifier resin emulsion prepared by dissolving it in a solvent and dispersing it in water using an emulsifier such as an ammonia casein aqueous solution is calculated based on the solid content weight of 100 parts of Roprene latex. It is obtained by blending 0.1 to 10 parts of a metal salt and 710 to 100 parts of a resin emulsion for tackifier.
