Title:
EPOXY RESIN COMPOSITION AND METHOD OF REINFORCING DAMPING AND SOUNDPROOFING OF METAL PLATE USING THE SAME
Document Type and Number:
Japanese Patent JPS5516073
Kind Code:
A
Abstract:
PURPOSE: To prepare an epoxy resin composition useful for the reincorcement, damping and soundproofing of a metal plate without sinking or restrictions from the pot life, at relatively low cost, by mixing an epoxy resin with a curing agent which is activated by heating, and a blowing agent which generates gas by heating.
CONSTITUTION: A composition composed of (A) 100 parts by weight of an epoxy resin, (B) (pref. 1W15 parts of) a curing agent which is activated by heating to 80W 200° C, e.g. dicyandiamide, 4,4'-diaminodiphenylsulfone, N,N-dialkylurea derivative, etc., and (C) a blowing agent which generates gas by heating, e.g. azodicarbonamide, dinitrosopentamethylenetetramine, p-toluenesulfonylhydrazide, etc.
