Connection sealing ring

Abstract

The invention discloses a connection sealing ring which consists of the following raw materials in parts by mass: 25-30 parts of silicon rubber, 35-40 parts of chloroprene rubber, 20-30 parts of nitrile butadiene rubber, 40-50 parts of ethylene propylene rubber, 20-30 parts of fluororesin, 30-35 parts of butyl rubber, 36-38 parts of styrene butadiene rubber, 30-35 parts of butadiene rubber, 2-3 parts of active calcium, 3-5 parts of active zinc oxide, 4-6 parts of light magnesium oxide, 5-8 parts of dolomite powder, 6-8 parts of superfine powder of hydrated magnesium silicate, 5-6 parts of glyceryl tribenzoate, 4-5 parts of triglyceride fatty acid ester, 3-4 parts of hydroxyethyl methacrylate, 3-5 parts of polyether polyol and 10-15 parts of aluminum hydroxide. The connection sealing ring has the advantages of tight connection, strong resistance against external force pulling, convenience in mounting, high reliability, good resistance against strong oxidation, lasting good elasticity, applicability to long-term use, good ozone resistance, high tear strength and rare compressive deformation.

Description

technical field [0001] The invention relates to the technical field of sealing rings, in particular to a connecting sealing ring. Background technique [0002] There are various kinds of existing sealing rings, and the material formulas used are also various, and the functions and purposes achieved are different. However, the existing sealing rings have insufficient elasticity and strong oxidation resistance. It is not ideal, it cannot maintain good elasticity for a long time, it is suitable for short-term use, the ozone resistance is not ideal, the tear strength is not enough, and it is easy to be compressed and deformed. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a connecting sealing ring, which has tight connection, strong resistance to external force pulling, convenient installation, high reliability, excellent resistance to strong oxidation, and long-term maint...
