PURPOSE: To obtain a metal noncorrosive rubber composition, improved in metal noncorrosiveness and suitable as rubber hose and vibration damping rubber by blending a chlorine-containing rubber with an acid acceptor and diphenyl ether halide in a specific proportion. n CONSTITUTION: A metal noncorrosive rubber composition, obtained by blending 100 pts.wt. chlorine-containing rubber (preferably epichlorohydrin rubber, etc.) with 1-20 pts.wt., preferably 2-15 pts.wt. acid acceptor (preferably magnesium oxide, etc.) and 1-30 pts.wt., preferably 6-20 pts.wt. diphenyl ether halide (preferably having 5-10 number of bound halogens) and preferably an activator, such as pentaerythritol, an assistant, such as antimony trioxide, a crosslinking agent, such as triallyl isocyanurate, excellent in heat, oil resistance and flame retardance and suitable as automotive members. n COPYRIGHT: (C)1990,JPO&Japio |
