Problems solved by technology

The rubber components of the domestic vehicle braking system booster have serious quality problems, such as tensile strength, elongation, tear resistance, impact elasticity, compression and tensile deformation, heat aging resistance, etc., which cannot meet the requirements. Therefore, most of the rubber parts of medium and high-end cars are imported.

Abstract

The present invention relates to sealing rubber assembly for booster of automobile brake system and its making process. The materials include styrene butadiene rubber, carbon black, dioctyl phthalate, indirectly prepared zinc oxide, stearic acid, antiager, sulfur S-80, vulcanizing agent DTDM and promoter in certain weight proportion. The making process includes mixing the materials and synthesizing the rubber in a Banbury mixer; roll mixing the rubber material in a blending roll to form and vulcanizing in a vulcanizer at the pressure of 120-160 Kgf / sq cm and temperature of 190-200 deg.c for 80-100 sec. The product of the present invention has high tensile strength, great elongation, high tear strength, etc.

Description

technical field [0001] The invention relates to a rubber component for a vehicle, in particular to a rubber component used for a booster of a vehicle brake system and a manufacturing process thereof. Background technique [0002] In recent years, vacuum boosters have been more and more widely used in automobile braking systems. Light buses, cars, and commercial vehicles all use this structure, and most light trucks also use it. With the continuous prosperity of the car market, the use of vacuum boosters has been increasing year by year. However, because the rubber parts of the vacuum booster for medium and high-end cars are key parts, they are also a weak link in domestic cars. The rubber components of the domestic vehicle braking system booster have serious quality problems, such as tensile strength, elongation, tear resistance, impact elasticity, compression and tensile deformation, heat aging resistance, etc., which cannot meet the requirements. Therefore, most of the ru...
