SILANE COUPLING AGENT FOR PRODUCING MOLDED ARTICLE OF EPOXY RESIN REINFORCED WITH GLASS FIBER

摘要

PURPOSE: To obtain a silane coupling agent which is readily soluble in water and with which a molded glass-fiber-reinforced epoxy resin article having excellent soldering heat resistance can be produced in a short time, by using a specific aminosilane compound or a salt thereof. ;CONSTITUTION: An aminosilane compound, N-(P-trimethyl)-γ- aminopropyltriethoxysilane hydrochloride represented by the formula (wherein R¹ is H, methyl, or ethyl; (m) is 0-3; (n) is 1-6; and R² is a 1-10C alkyl) is obtained, for example, by introducing 1.0mol of γ-aminopropyltriethoxysilane as a feedstock aminosilane into a reaction vessel, heating it to 60-80°C, dropping 1.0mol of α-chloro-p-xylene as a halide thereinto, and reacting the mixture under stirring at 60-80°C for 16hr. Methanol is added to this hydrochloride. Glass fibers are immersed in the resultant methanol solution as a surface treatment agent and then dried at 100-120°C to obtain surface-treated glass fibers, which are impregnated with an epoxy resin to obtain a molded glass-fiber- reinforced epoxy resin.;COPYRIGHT: (C)1996,JPO
