Cured novolak fiber-reinforced, chlorinated rubber molded articles having excellent flame-proofness, and process for the preparation thereof

摘要

This invention relates to a cured novolak fiber-reinforced, chlorinated rubber molded article having excellent flameproofness, the main components of which arePP(A) fibers or a fibrous structure containing at least 50 weight % of cured novolak fibers and PP(B) a rubber composition consisting mainly of chlorinated rubber as a rubber component,PPthe content of said fibers or fibrous structure being 2-80% by weight; and a process for the preparation of said article comprising adhering an organic solvent solution or dispersion of the rubber composition (B) to the fibers or the fibrous structure (A) or impregnating the fibers or fibrous structure with said solution or dispersion, or mixing the fibers with the rubber composition (B), and without any further processing, or during or after the pressing or molding, vulcanizing said chlorinated rubber composition at a temperature of 100°-200° C.
