Surface modifying compositions for vulcanized rubber and method of modifying vulcanized rubber surface using the same

摘要

A surface modifying composition for vulcanized rubber comprises a halogen-releasable halogenoid and a waxy substance having a melting point of not more than 100° C. and an inorganic filler, and is non- solvent type. The weight of the inorganic filler is in a range of 15-80% based on the whole surface modifying composition, and 0.6-20 times that of the halogen-releasable halogenoid. In the surface modification of vulcanized rubber, the surface coated with the surface modifying composition is heated at 60°-150° C.
