Wear-resistant rubber sealing ring

Abstract

The invention discloses a wear-resistant rubber sealing ring. The wear-resistant rubber sealing ring comprises the following raw materials in parts by weight: 9-12 parts of ethylene propylene diene monomer rubber, 6-7 parts of butadiene-styrene rubber, 2-4 parts of zinc oxide, 7-12 parts of white carbon black, 3-5 parts of a promoter, 4-6 parts of a foaming agent, 7-8 parts of naphthenic oil, 26-29 parts of titanium dioxide, 30-40 parts of natural rubber, 12-15 parts of Rhein chemie processing auxiliary, 12-13 parts of silicone rubber, 1-2 parts of silicon carbide, and 1-3 parts of melamine. Through complex formulation of the materials such as zinc oxide, the obtained sealing ring has the advantages of good hardness, abrasive resistance, long service life, and difficult abrasion.

Description

technical field [0001] The invention belongs to a wear-resistant rubber sealing ring. Background technique [0002] In the prior art, the rubber sealing ring is an annular cover composed of one or several parts, which is fixed on a ferrule or washer of the bearing and contacts with another ferrule or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and Intrusion of foreign objects, with rubber elastic body (nitrile, fluororubber, silica gel, natural rubber and other rubber) as the main material, reinforced cloth (nylon, glass fiber, Nomex, and other special reinforced cloth) as the skeleton, can According to customer requirements, different elastic bodies and skeletons are selected to process rubber diaphragms of different thicknesses. Due to the constant friction between objects and workpieces, as the friction time increases, the appearance of the object will be damaged or even lose its original performance. . For example, rubber sealing ri...
