Problems solved by technology

This is mainly because with the development of the automobile industry, the ambient temperature of the medium used by automobile engines and other components is getting higher and higher. The temperature is usually as high as 130-150°C or even higher. High-temperature oil and gas are prone to early aging of traditional nitrile oil-resistant hoses. Cause the nozzle seal is not tight, air leakage, oil leakage, etc., thus affecting the normal operation of the vehicle

Abstract

The invention relates to an oil and high temperature resistant acrylate rubber tube. The rubber tube comprises or contains the following components in parts by weight: 100 parts of acrylate rubber, 1-10 parts of light magnesium oxide, 1-5 parts of stearic acid, 1-5 parts of anti-aging agent TR-101, 1-5 parts of pentaerythritol ester, 5-15 parts of precipitated hard charcoal, 15-60 parts of natural gas semi-reinforced carbon black, 15-60 parts of fast extruding furnace black N550, 15-60 parts of heavy carbonic acid, 1-10 parts of plasticizer TP-95, 0.5-2 parts of sulfur, 0.5-5 parts of 1# accelerant, 0.5-5 parts of 2# accelerant and 0.5-5 parts of 3# accelerant. The rubber tube has the best physical and mechanical properties. Through tests, the hardness of the rubber tube is 70+ / -5 degrees, the tensile strength is more than 8MPa, the elongation at break is more than 200%, the rubber tube can be used for a long term in a 150 DEG C high-temperature oil medium environment, and the 3# oil weight change resistance is lower than 25%.

Description

technical field [0001] The invention belongs to the technical field of rubber formulations, in particular to an oil-resistant and high-temperature-resistant acrylate rubber hose. Background technique [0002] As we all know, nitrile rubber (NBR) is widely used in the automobile industry because of its excellent oil resistance and good heat resistance (maximum service temperature 130°C). With the development of the automobile industry, it is required to have high temperature resistance and weather resistance. Materials that also have excellent oil resistance and meet environmental requirements are becoming increasingly prominent. This is mainly because with the development of the automobile industry, the ambient temperature of the medium used by automobile engines and other components is getting higher and higher. The temperature is usually as high as 130-150°C or even higher. High-temperature oil and gas are prone to early aging of traditional nitrile oil-resistant hoses. C...
