Abstract

The invention provides a nitrile rubber sealing ring. According to the technical scheme, the nitrile rubber sealing ring comprises a main material and an auxiliary material. The main material comprises nitrile rubber, the auxiliary material comprises silicone rubber, perfluoroether rubber, polyether-ether-ketone, chlorosulfonated polyethylene, a vulcanizing agent, a softener, an adhesive, an accelerant DPTT, a reinforcing agent, a flame retardant and color masterbatch, and the softener is composed of paraffin and asphalt. The vulcanizing agent is made of N '-phenylene bismaleimide. The nitrilerubber sealing ring has the beneficial effects that the silicon rubber, the perfluoroether rubber and the polyether-ether-ketone are added according to a proper proportion, so that the temperature resistance is effectively improved, and the nitrile rubber sealing ring can be used for a long time in a high-temperature environment; in addition, the performance of the sealing ring is comprehensivelyimproved by adding the chlorosulfonated polyethylene and the vulcanizing agent, the flame retardant effect of the sealing ring is greatly improved by adding the flame retardant, and fire accidents are also reduced.

Description

technical field [0001] The invention relates to the technical field of nitrile rubber, in particular to a nitrile rubber sealing ring. Background technique [0002] Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. , its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used to manufacture oil-resistant rubber products. It is a synthetic rubber prepared by copolymerization of butadiene and acrylonitrile. It is oil-resistant 1. Synthetic rubber with better aging resistance. The more acrylonitrile content in nitrile rubber, the better the oil resistance, but the cold resistance will decrease accordingly. It can be used for a long time in the air at 120°C or in th...
