Abstract

The invention provides oil-resistant and anti-aging acrylate rubber and a preparation method thereof. The acrylate rubber is prepared from raw materials as follows: 70-80 parts of acrylate rubber, 20-30 parts of natural rubber, 5-8 parts of polyvinyl alcohol, 2-4 parts of nano zinc oxide, 5-10 parts of fumed silica, 4-8 parts of carbon black N550, 2-3 parts of an anti-aging agent, 3-6 parts of dibutyl phthalate, 1-3 parts of sulfur and 1-2 parts of a softening plasticizer. Multiple components are added to the oil-resistant and anti-aging acrylate rubber, and the excellent aging resistance is guaranteed while the crosslinking density and the oil resistance are improved. The produced product has higher chemical stability, is safe and environmentally friendly and has good tensile strength, high oil resistance and oxidation resistance and excellent mechanical performance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an oil-resistant and anti-aging acrylate rubber and a preparation method thereof. Background technique [0002] The application of rubber is becoming more and more common in daily life and industry. For rubber products in contact with oil, during long-term use, oil can penetrate into the interior of the rubber and cause it to swell; on the other hand, oil can be vulcanized from The soluble compounding agent is extracted from the rubber, resulting in a decrease in the volume of the vulcanized rubber. In addition, some additives in synthetic lubricating oil can chemically interact with rubber and erode polymer chains; especially at high temperatures, they can cause crosslinking or degradation of rubber, and when the erosion is severe, rubber products will lose their ability to work. [0003] In recent years, the development and production of synthetic rubber has made up for the sho...
