METHOD FOR PRODUCING HEAT-RESISTANT RESIN COMPOSITION, HEAT-RESISTANT RESIN COMPOSITION PRODUCED BY METHOD FOR PRODUCING HEAT-RESISTANT RESIN COMPOSITION, AND MOLDED ARTICLE USING HEAT-RESISTANT RESIN COMPOSITION

摘要

A method for producing a heat-resistant resin composition, which is characterized by comprising (a) a step wherein a silane master batch is prepared by melting and kneading a resin composition that contains a polyolefin resin, 0.01-0.6 part by mass of an organic peroxide and 10-400 parts by mass of an inorganic filler per 100 parts by mass of the resin composition, and 0.5-15.0 parts by mass of a silane coupling agent per 100 parts by mass of the inorganic filler at a temperature not less than the decomposition temperature of the organic peroxide, without mixing a silanol condensation catalyst thereinto, (b) a step wherein the silane master batch is melted and kneaded with a silanol condensation catalyst, and then the resulting is molded, and (c) a step wherein the molded product of the step (b) is crosslinked by being brought into contact with a water content; a heat-resistant resin composition which is produced by this method for producing a heat-resistant resin composition; and a molded article which contains a molded product of this heat-resistant resin composition.
