Abstract

The invention discloses a nitrile rubber material for a high-performance engine. The nitrile rubber material comprises the following raw materials in parts by weight: 70-100 parts of nitrile rubber 3604, 20-30 parts of ethylene propylene diene monomer, 4-10 parts of organic silicon modified acrylate, 4-6 parts of polyvinyl chloride resin, 0.8-1.3 parts of stearic acid, 1.5-2.5 parts of paraffin, 40-60 parts of carbon black N550, 15-30 parts of zinc oxide whiskers, 8-12 parts of coupling agent KH-550, 13-17 parts of high styrene, 0.7-1.3 parts of trihydroxymethylaminomethane, 1.5-2.1 parts of dicumyl peroxide, 0.5-0.8 part of N,N-diphenyl-phenylene diamine, 0.3-0.5 part of antiager MB, 0.7-1 part of trimethylol-propane trimethacrylate, 1-2 parts of triallyl isocyanurate, 3-8 parts of magnesium hydrate, 1-3 parts of antimonous oxide, 8-13 parts of diethylene glycol dibenzoate and 0.5-1 part of accelerant TMTD. The nitrile rubber material for the high-performance engine disclosed by the invention is excellent in oil resistance, excellent in high temperature resistance, and good in wear-resisting property, warping strength and breaking performance, can be applied to preparation of various sealing materials inside the engines, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of nitrile rubber, in particular to a nitrile rubber material for high-performance engines. 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. . Nitrile rubber is mainly used to make oil-resistant products, such as oil-resistant pipes, tapes, rubber diaphragms and large oil bags, etc. It is often used to make various oil-resistant molded products, such as O-rings, oil seals, leather cups, diaphragms, valves, bellows , hoses, seals, foaming, etc., are also used to make rubber sheets and wear-resistant parts. [0003] With the rapid development of the current industrial field, the high and low temperature resistance, oil resistance, wear resistance, and flex resistance of ...

AI Technical Summary

Problems solved by technology

[0003] With the rapid development of the current industrial field, the high and low temperature resistance, oil resistance, wear resistance, and flex resistance of the internal sealing materials of the engine have put forward strict requirements. The cycle operation of an engine requires air absorption, compression, high temperature power generation, and waste discharge. And other key processes, in this process will produce high temperature, high pressure, friction, fuel flame explosion and other phenomena, so the sealing material of an engine must involve high temperature, high pressure, high explosive force, high power, fuel oil, high temperature waste and low pollution emissions Various complex media and performance tests, which put forward higher requirements for sealing materials. Traditional sealing materials can no longer meet the design and use requirements of contemporary engines. How to prepare a long service life, excellent oil resistance and high temperature resistance? , wear-resistant, flex-resistant, and good tear-off performance of the nitrile rubber material for engines has become a technical problem that needs to be solved at present
