RUBBER COMPOSITIONS FOR TIRE INNER LINER IMPROVING THERMAL CONDUCTIVITY AND FATIGUE RESISTANCE

摘要

PURPOSE: A rubber composition for a tire innerliner is provided to use a rubber composition as a reinforcing filler, thereby remarkably improving thermal conductivity and fatigue resistance. CONSTITUTION: A rubber composition for a tire innerliner comprises 30 parts by weight of a butyl-based rubber, 20-70 parts by weight of a carbon black, and 5-30 parts by weight of a highly crystalline carbon black based on 100.0 parts by weight of a raw rubber. The raw material rubber comprises one or more butyl-based rubber selected from butyl rubber and halobutyl rubber, natural rubber, synthetic rubber, or a mixture of a natural rubber and synthetic rubber.
