BONDING METHOD USING AQUEOUS CONTACT TYPE ADHESIVE

摘要

PROBLEM TO BE SOLVED: To provide a bonding method using an aqueous contact type adhesive having good workability and high safety to human bodies and the environment. SOLUTION: This bonding method using the aqueous contact type adhesive comprises applying the aqueous contact type adhesive composed of (A) an anionic group-containing alkoxysilyl group-terminated urethane prepolymer obtained by reacting (A1) a polyol compound not containing an anionic group with (A2) an anionic group-containing polyol compound, (A3) a polyisocyanate compound and (A4) a primary or secondary amino group-containing alkoxysilane compound, (B) a basic compound and (C) water onto the surface of at least either one adherend of adherends (I) and (II) to be laminated and then laminating the adherend (I) to the adherend (II) through an adhesive layer by the aqueous contact type adhesive formed on the adherend (I) and/or the adherend (II) in a state in which adhesiveness by the aqueous contact type adhesive is developed after passage of a prescribed time.
