Abstract

The invention relates to the technical field of rubber, and concretely relates to a high-performance nitrile rubber material and a preparation method thereof. The high-performance nitrile rubber material is prepared by taking rubber, silicone rubber and carbon quantum dots as main raw materials; the rubber is selected from one or more of nitrile rubber, carboxy nitrile rubber, hydrogenated nitrile rubber and hydrogenated carboxy nitrile rubber; the particle size of the carbon quantum dots is 1-3 nm; and the weight ratio of the rubber to the silicon rubber to the carbon quantum dots is (50-80): (20-50): (0.5-10). According to the high-performance nitrile rubber material provided by the invention, the nitrile rubber, the silicone rubber and the carbon quantum dots are adopted as main raw materials, so that the high-performance nitrile rubber material not only has good oil resistance, but also has good low-temperature resistance, wear resistance, heat resistance and ozone resistance. In addition, the preparation method of the high-performance nitrile rubber material is simple, and the high-performance nitrile rubber material has a good industrial foundation and a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high-performance nitrile rubber material and a preparation method thereof. Background technique [0002] Nitrile rubber is prepared by emulsion polymerization of butadiene and acrylonitrile. It has excellent oil resistance, good wear resistance and heat resistance, but its low temperature resistance and ozone resistance are poor. There is a contradiction between the oil resistance and low temperature resistance of nitrile rubber. How to obtain a nitrile rubber with excellent oil resistance and good low temperature resistance is a major difficulty in the research of nitrile rubber. [0003] CN111171419A discloses a high-strength low-temperature resistant nitrile rubber O-shaped sealing ring, which is prepared from the following raw materials in parts by weight: 60 parts of nitrile rubber, 40 parts of silicon rubber, 5-15 parts of white carbon black, 10-20 parts of carbon black, ...
