Abstract

PURPOSE: Titled composition that is made by adding a dithiocarbamate as a vulcanizing accelerator with specific structure to the rubber component specifically composed of ethylene-propylene-diene terpolymer rubber, thus showing high resistance to ozone as well as flexing and high vulcanizing adhesion.
CONSTITUTION: To (A) 100pts.wt. of rubber component consisting of (a) 30W45 parts of ethylene-propylene-diene rubber of more than 25 iodine value, preferably ethylene-propylene-ethylidenenorbornene terpolymer rubber, (b) 15W35 parts of styrene-butadiene copolymer rubber and (c) 35W50 parts of natural and/or polyisoprene rubber, are added (B) 1W5 parts of long-chain alkyldithiocarbamate of the formula (R1 and R2 are 10W20C alkyl; Me is Zn, Fe, Cu, Se, Te, Ni, Na, Bi, Hg, or Pb; n is valency of Me), preferably zinc distearyldithiocarbamate, as a vulcanizing accelerator.
USE: Side wall of car tire and air spring.
