Abstract

The invention discloses high-performance low-pressure-change HNBR rubber material which is prepared from the following components in parts by weight: 100 parts of hydrogenated butadiene-acrylonitrilerubber HBNR, 15-25 parts of carbon black N660, 10-20 parts of modified argil, 3-6 parts of zinc oxide, 2-5 parts of methacrylic acid, 11-15 parts of white oil, 1-3 parts of stearic acid, 1-2 parts ofsulfur, 0.8-1.5 parts of an anti-aging agent DFL, 0.2-1 part and 1-3 part of plasticizer. The rubber material has excellent basic physical properties, good high and low temperature resistance, good rebound resilience and low compression set, and is suitable for being applied to the field of automobile rubber tubes.

Description

technical field [0001] The invention belongs to the field of rubber, in particular to a high-performance low-pressure variable HNBR rubber material. Background technique [0002] With the development of the automobile industry and the popularization of cars, the domestic requirements for the quality of automobile starting and sealing systems are getting higher and higher. Because the various systems are frequently used when the car is running at high speed, a large amount of frictional heat will inevitably cause the temperature of each system to rise. Wear or corrosion of the rubber parts within each system will become increasingly severe. When the rubber seal is damaged to a certain extent, the sealing effect will not be achieved, which will cause the entire system to lose its function. In order to ensure the safety and reliability of the braking system, sealing system and other systems under various temperatures and high-frequency usage conditions, the rubber seal materi...
