ADHESION STRUCTURE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an adhesion structure which can be strongly bonded to a silicone composition by mounting a primer layer composed of a polyurethane or a derivative of the polyurethane on a surface of a graphite sheet. SOLUTION: An adhesion structure obtained by mounting a primer layer composed of a polyurethane or a derivative of the polyurethane on a surface of a graphite sheet is strongly bonded to a silicone composition as exemplified in that the graphite sheet is coated with a resin solution diluted by a solvent, is dried and is heated for curing and then a silicone rubber compound is rolled and is laminated on the graphite sheet followed by heating and vulcanization.
