Anti-aging rubber sealing ring

Abstract

The utility model relates to the technical field of sealing rings, and discloses an anti-aging rubber sealing ring which comprises a composite rubber sealing ring body, the composite rubber sealing ring body comprises an elastic anti-breaking metal wire, a natural rubber layer is fixedly installed on the outer wall of the elastic anti-breaking metal wire, and an acrylate rubber layer is fixedly installed on the outer wall of the natural rubber layer. A polyurethane rubber layer is fixedly mounted on the outer wall of the acrylate rubber layer, and the anti-aging composite rubber layer formed by compounding the anti-aging composite rubber layer, the hydrogenated nitrile rubber layer, the silicone rubber layer, the ethylene propylene diene monomer layer and the fluorinated silicone rubber layer is arranged, so that the anti-aging performance of the whole composite rubber sealing ring can be greatly improved; the problem that the material of the composite rubber sealing ring is gradually aged and the performance of the composite rubber sealing ring is reduced due to the influence of external environmental factors is avoided, the service life of the whole composite rubber sealing ring is prolonged, and the threat to the safety of equipment due to the reduction of the aging performance of the composite rubber sealing ring is avoided.
