<P>PROBLEM TO BE SOLVED: To provide a thermally peelable aqueous adhesive which contains no expensive thermally expansible hollow body, is used for adhesion of a composite material, has indoor durability, heat resistance and adhesivity of about several years in use, and on the other hand, can easily repeel the composite material by a simple heating fixture such as a household electric iron when the composite material is disused. <P>SOLUTION: The thermally peelable aqueous adhesive includes a water dispersion liquid (A) containing a polymer (a) to form a film of 1 to 28 MPa in film tensile strength, a water dispersion liquid (B) containing an adhesiveness imparting resin (b) of 70 to 150°C in melting point, and a water dispersion liquid (C) containing a wax (c) of 75 to 120°C in melting point. <P>COPYRIGHT: (C)2013,JPO&INPIT |
