Problems solved by technology

[0002] Because when petroleum products are used, the environment they are in is often in contact with the sealing material rubber rings of facilities and equipment, so it is necessary to conduct sealing adaptability tests on petroleum products and their corresponding rubber sealing rings. Traditional rubber sealing rings on the market , used in various fields of production and life, if in harsh environments, rubber rings have certain requirements for oil resistance, heat resistance, and corrosion resistance, but now the rubber rings on the market often fail to meet the requirements, which is not conducive to production and life

Embodiment Construction

[0008] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0009] An oil-resistant seal ring rubber material, which is composed of the following raw materials in parts by mass: 26 parts of natural rubber, 34 parts of nitrile rubber, 4 parts of stearic acid, 5 parts of zinc oxide, 1 part of anti-aging agent, and high wear-resistant carbon black 29 parts, 1 part of accelerator.

[0010] In this example, the anti-aging agent is N-phenyl-β-aniline.

[0011] In addition, the accelerator is tetrazinc disulfide methylthiuram.

[0012] The advantage of the present invention is that the oil-resistant rubber sealing ring not only has good oil resistance, corrosion resistance and good air tightness, but also has excellent flame retardancy and insulation, and the internal bonding force of the rubber sealing ring is ...

Abstract

The invention discloses an oil-resistant rubber sealing ring material which comprises raw materials in parts by mass as follows: 25-48 parts of natural rubber, 32-44 parts of nitrile butadiene rubber, 3-5 parts of stearic acid, 3-12 parts of zinc oxide, 0.5-2 parts of an anti-aging agent, 20-32 parts of high-wear-resistant carbon black and 0.5-1.5 parts of an accelerant. An oil-resistant rubber sealing ring has good oil resistance, corrosion resistance and air tightness and has excellent flame retardance and insulation performance, the inner bonding force of the rubber sealing ring is large, the tensile resistance, the aging resistance, the acid and alkali resistance and the like of the rubber sealing ring are effectively improved, and the material is widely applied to industrial production and people's life.

Description

technical field [0001] The invention relates to the field of rubber products, in particular to an oil-resistant sealing ring rubber material. Background technique [0002] Because when petroleum products are used, the environment they are in is often in contact with the sealing material rubber rings of facilities and equipment, so it is necessary to conduct sealing adaptability tests on petroleum products and their corresponding rubber sealing rings. Traditional rubber sealing rings on the market , used in various fields of production and life, if in harsh environments, rubber rings have certain requirements for oil resistance, heat resistance, and corrosion resistance, but now the rubber rings on the market often fail to meet the requirements, which is not conducive to production and life . Contents of the invention [0003] The object of the present invention is to provide a rubber material for an oil-resistant sealing ring to solve many defects in the prior art. [00...
