Abstract

Disclosed is a vibration-damping reinforcing composition containing 30-300 parts by weight of a butyl rubber, 30-300 parts by weight of an acrylonitrile-butadiene rubber, 100 parts by weight of an epoxy resin, and 0.5-30 parts by weight of an epoxy resin curing agent.

Description

technical field [0001] The present invention relates to a vibration-damping reinforcement composition, a vibration-damping reinforcement material, and a vibration-damping reinforcement method of a thin plate. Background technique [0002] In order to prevent deformation due to external stress, thin plates used in structures such as automobiles and home appliances have required increased reinforcement. [0003] For example, by preparing a steel sheet reinforcing resin composition containing an epoxy resin, acrylonitrile-butadiene rubber, a curing agent, and a foaming agent, and rolling it to form a resin layer, by laminating a reinforcing layer on the resin layer, A steel plate reinforced sheet was obtained. Furthermore, it has been proposed to reinforce the steel plate by foaming and solidifying this steel plate reinforcing sheet after sticking it to the steel plate (for example, Patent Document 1 below). [0004] In addition, since thin plates generate vibration noise dur...
