METHOD FOR PRODUCING RUBBER ROLLER AND RUBBER COMPOSITION

摘要

A method for producing a rubber roller includes preparing a rubber composition containing epichlorohydrin rubber and a conductive agent, the epichlorohydrin rubber being an epichlorohydrin-ethylene oxide-allyl glycidyl ether ternary copolymer that contains an ethylene oxide-derived structural unit within a range of 40 mol % or more and 60 mol % or less relative to the entire ternary copolymer, and a content of calcium oxide being 1 part by weight or less relative to 100 parts by weight of the epichlorohydrin rubber; removing a volatile component so that a ratio of the volatile component contained in the rubber composition is 0.8% by weight or less relative to the entire rubber composition; coating a periphery of a core body with the rubber composition to form a rubber composition layer; and vulcanizing the rubber composition layer under atmospheric pressure to form a rubber layer on the periphery of the core body.
