Abstract

The invention discloses an oil resistant gasket characterized by comprising the following raw materials by weight: 80-120 parts of high acrylonitrile NBR, 3-7 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 0.1-0.3 part of sulfur, 10-30 parts of semi reinforcing furnace black, 25-45 parts of active calcium carbonate, 5-15 parts of plasticizer DOS, 3-7 parts of plasticizer TP-90B, 1-3 parts of promoter CZ and 1-3 parts of promoter TMTD. Compared with the prior art, the oil resistant gasket has the following advantages: (1) the product of the oil resistant gasket has the advantages of low price, less use of raw materials and simple production process; (2) the oil resistant gasket has the advantages of being safe, environmentally friendly, good in oil resistance, heat resistance and aging resistance and other a series of advantages; and (3) by simultaneous use of the NBR and PVC, the manufactured oil resistant gasket has excellent resistance to bending, and high fatigue resistance and sealing performance.

Description

technical field [0001] The invention relates to the scientific field of rubber materials, in particular to an oil-resistant gasket. Background technique [0002] Nitrile-butadiene rubber (NBR) 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 good viscosity. The relay is strong. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor electrical properties, and slightly lower elasticity. Nitrile rubber is mainly used in the manufacture of oil-resistant rubber products. Such as rubber hoses, rubber rollers, sealing gaskets, storage tank linings, aircraft fuel tank linings, and large oil bags that are in contact with oil. Utilizing the good heat resistance of NBR, it is also possible to manufacture conveyor belts for transporting hot materials (below 140°C). It can also ...
