Abstract

PURPOSE: To provide a rubber compsn., free from precuring phenomenon and excellent in storage stability, containing a curing accelerator coated with a resin having a melting point lower than the curing temp. of the compsn.
CONSTITUTION: A mixt. of a curing accelerator (e.g. zinc diethyldithiocarbamate) crushed to a specified particle size and a resin with a melting point (or softening point) lower than the curing point (e.g. synthetic polyterpene resin with a softening point of about 85°C is heated to a temp. above the melting point (or softening point) of the fesin and thoroughly kneaded. The mixt. is cooled and crushed to a specified particle size. The resultant resin-coated curing accelerator and other additives (e.g. sulfur, zinc white, reinforcing agent, age resister) are blended into a base resin (e.g. natural rubber, polyisoprene rubber) to produce the rubber compsn.
