Problems solved by technology

[0002] Rubber has good comprehensive properties, such as high adhesion to metal, mechanical properties, fatigue properties, aging resistance, and low heat generation. Rubber sealing rings are used in all walks of life. It will bring losses and troubles, and it will cause serious accidents, especially in the environment with high working pressure, the seal ring bears a large load, and the seals are often damaged during the operation of the equipment. Some seals only If it can be used for 1-2 months, or even shorter, it needs to be replaced, which brings troubles to the continuous production of enterprises, and people's quality requirements for rubber sealing rings are also constantly improving. Therefore, there is an urgent need for a long-life , Good performance rubber sealing material

Embodiment 1

[0013] A rubber material for wear-resistant seals, which is composed of the following raw materials in parts by mass: 42 parts of nitrile rubber, 12 parts of EPDM rubber, 18 parts of epoxy resin, 11 parts of high wear-resistant white carbon black, 4 parts of carbon fiber 3 parts, 3 parts of propylene alcohol, 5 parts of vulcanizing agent, 1 part of accelerator, 2 parts of anti-aging agent, 2 parts of plasticizer.

[0014] It should be noted that the plasticizer is a mixture of potassium laurate, sodium salicylate and polyethylene glycol.

[0015] In this example, the vulcanizing agent is urethane.

[0016] In this example, the accelerator is the accelerator TMTD.

[0017] In addition, the anti-aging agent is anti-aging agent 4010 and anti-aging agent D used together.

Embodiment 2

[0019] A rubber material for wear-resistant seals, which is composed of the following raw materials in parts by mass: 38 parts of nitrile rubber, 14 parts of EPDM rubber, 19 parts of epoxy resin, 11 parts of high wear-resistant white carbon black, 4 parts of carbon fiber 3 parts, 3 parts of propylene alcohol, 5 parts of vulcanizing agent, 1 part of accelerator, 2 parts of anti-aging agent, 2 parts of plasticizer.

[0020] It should be noted that the plasticizer is a mixture of potassium laurate and sodium salicylate.

[0021] In this example, the vulcanizing agent is urethane.

[0022] In this example, the accelerator is the accelerator TMTD.

[0023] In addition, the anti-aging agent is anti-aging agent 4010 and anti-aging agent D used together.

[0024] Based on the above, in this scheme, nitrile rubber is used as the matrix, and wear-resistant materials such as carbon fiber, epoxy resin and high wear-resistant white carbon black are used as filling materials, which have h...

Abstract

The invention discloses a rubber material for a wear-proof sealing part. The rubber material for the wear-proof sealing part is characterized by being prepared from the following raw materials in parts by mass: 35-55 parts of butadiene-acrylonitrile rubber, 10-15 parts of ethylene propylene diene monomer rubber, 15-20 parts of epoxy resin, 10-15 parts of high-wear-resistance white carbon black, 3-4 parts of carbon fibers, 3-5 parts of allyl alcohol, 5-8 parts of a vulcanizing agent, 1-3 parts of an accelerator, 2-4 parts of an anti-aging agent and 2-4 parts of a plasticizer. According to the technical scheme, butadiene-acrylonitrile rubber is taken as matrix, and wear-resistant materials such as carbon fibers, epoxy resin and high-wear-resistance white carbon black are taken as filling materials, so that the rubber material for the wear-proof sealing part has high strength, internal bonding strength of rubber is improved, and the tensile strength and mechanical strength of the rubber are enhanced.
