摘要：
A chromate-free resin composite damping material is provided having a multilayer structure. The material can include an viscoelastic resin composition provided between two metal plates as an intermediate layer, where the viscoelastic resin composition can include a thermosetting resin further including an amorphous copolymerizable polyester resin and a curing agent. A surfaces of each metal plate contacting the resin composition can be provided with a chromate-free adhesion boundary film which includes between about 5 and 50 mass % of silica, between about 5 and 50 mass % of a polyester resin, between about 1 and 50 mass % of tannic acid, and between about 0 and 30 mass % of a silane coupling agent. Such damping material can provide excellent durable adhesion properties.
