Problems solved by technology

[0002] Automotive fuel pump seals are not only related to the normal use of the fuel pump but also to the safety of the vehicle. In the prior art, there are often problems such as oil leakage caused by the sealing performance of the seals, and even cause certain safety hazards to the vehicle.
The automotive fuel pump seals in the prior art are usually made of nitrile rubber, but nitrile rubber has the defects of poor wear resistance, toughness and high temperature resistance. Long-term use cannot guarantee the sealing effect of the seal, which needs to be solved urgently

Abstract

The invention discloses a high wear-resistant high-tenacity rubber sealing element which comprises the following raw materials in parts by weight: 30-50 parts of epichlorohydrin rubber, 12-20 parts of methyl vinyl silicone rubber, 20-30 parts of nitrile rubber, 6-12 parts of kieselguhr, 4-8 parts of calcium carbonate, 2-4 parts of magnesium oxide, 12-16 parts of bismuth oxide, 10-20 parts of barium metaborate, 8-16 parts of a glass bead, 4-8 parts of modified aupoz fiber, 2-4 parts of a dimethyl silicone polymer, 3-6 parts of methylphenyldiethoxysilane, 4-8 parts of an epoxidized fatty acid methyl ester, 1-3 parts of magnesium stearate, 2-4 parts of diisononyl phthalate, 0.4-1 part of triallylisocyanurate, 2-4 parts of zinc diacrylate and 1.5-3 parts of dicumyl peroxide. The high wear-resistant high-tenacity rubber sealing element not only has excellent wear resistance and tenacity, but also has very good high temperature resistance, and meanwhile, the sealing element is difficult to age and long in service life.

Description

technical field [0001] The invention relates to the technical field of sealing, in particular to a rubber seal with high wear resistance and high toughness. Background technique [0002] Automotive fuel pump seals are not only related to the normal use of the fuel pump but also to the safety of the vehicle. In the prior art, there are often problems such as oil leakage caused by the sealing performance of the seals, which may cause certain safety hazards to the vehicle. The automotive fuel pump seals in the prior art are usually made of nitrile rubber, but nitrile rubber has the defects of poor wear resistance, toughness and high temperature resistance. Long-term use cannot guarantee the sealing effect of the seal, which needs to be solved urgently. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a high wear-resistant and high-toughness rubber seal, which has excellent wear resistance and tough...
