METHOD FOR PRODUCING VULCANIZED RUBBER MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a vulcanized rubber molded product satisfying a dimensional standard by regulating shrinkage at vulcanization of a vulcanized rubber without correcting a mold. SOLUTION: The method for producing the vulcanized rubber molded product comprising charging the interior of the mold with an unvulcanized rubber composition, and heating the mold to vulcanize the rubber composition involves adding staple fibers to the unvulcanized rubber composition to regulate the shrinkage at the vulcanization of the vulcanized rubber by regulating the amount of the added staple fibers. The amount of the added staple fibers is preferably≤10 pts. wt. based on 100 pts. wt. rubber material constituting the unvulcanized rubber composition. COPYRIGHT: (C)2004,JPO
