HEAT RESISTANT CHLORINE-CONTAINING CROSSLINKED RESIN MOLDED BODY AND METHOD FOR PRODUCING THE SAME, SILANE MASTERBATCH AND MASTERBATCH MIXTURE, AND HEAT RESISTANT PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a heat resistant chlorine-containing crosslinked resin molded body which has excellent appearance and exhibits excellent heat resistance and a method for producing the same, a silane masterbatch and a mixture thereof which can form the heat resistant chlorine-containing crosslinked resin molded body, and a heat resistant product.SOLUTION: There are provided a method for producing a heat resistant chlorine-containing crosslinked resin molded body which includes: a step (a) of melting and mixing an organic peroxide, an inorganic filler and a silane coupling agent with a specific ratio in a base resin containing chlorinated polyethylene and polyvinyl chloride at a temperature equal to or higher than a decomposition temperature of the organic peroxide; a step (b) of mixing silane masterbatch obtained in the step (a) and a silanol condensation catalyst, and then molding the mixed substance; and a step (c) of bringing the molded body obtained in the step (b) into contact with moisture to crosslink, where in the step (a), a ratio of a content of the chlorinated polyethylene and the polyvinyl chloride in the base resin used at the time of the reaction with the silane coupling agent is 90:10 to 10:90 by a mass ratio; a heat resistant chlorine-containing crosslinked resin molded body produced by the same; a silane masterbatch and a mixture thereof; and a heat resistant product.SELECTED DRAWING: None
