RUBBER COMPOSITE OF DIAPHRAGM OF A BRAKE BOOSTER

摘要

The purpose of the present invention is to provide a rubber composition for the diaphragm of a break booster which improves tear, heat resistance and brake fluid resistance by basically enhancing the physical properties while using SBR rubber as the main polymers. The present invention provides the rubber composition for a brake booster diaphragm comprising: polymers which is formed by mixing styrene butadiene rubber (SBR rubber) and polybutadiene rubber (BR rubber), and additives including 3-7 parts by weight of molybdenum powders based on 100 parts by weight of the polymers and 0.5-3 parts by weight of Armoslip Cp based on 100 parts by weight of the polymers.
