RUBBER COMPOSITION FOR ADHESION OF STEEL CORD

摘要

PURPOSE: Provided is a rubber composition for adhesion of steel cord capable of increasing resistance to heat resistant aging and durability of tire and preventing the degradation of adhesion of steel cord and rubber. CONSTITUTION: The rubber composition comprises 2-4 phr of sulfur and 0.8-1.5 phr of benzothiazole sulfanamide as an accelerator with respect to 100 phr of rubber material consisting of natural rubber and epoxide natural rubber containing 50% epoxide. The weight ratio of the 50% epoxide natural rubber is 10-60% in a mixed rubber of natural rubber and epoxide natural rubber containing 50% epoxide.
