Abstract

The invention provides a corrosion resistant ethylene propylene diene monomer rubber and relates to the technical field of high polymer materials. The corrosion resistant ethylene propylene diene monomer rubber contains the raw materials of 80-100 parts of ethylene propylene diene monomer rubber, 18-25 parts of polytetrafluoroethylene, 15-23 parts of butyl rubber, 11-16 parts of fluororubber, 7-13 parts of chloroprene rubber, 20-25 parts of CR232 type chloroprene rubber, 5-11 parts of glass, 8-13 parts of wax candles, 14-19 parts of titanium silicon, 7-11 parts of monel 400 alloys, 12-18 parts of 316 stainless steel, 15-22 parts of carbon monofluoride, 5-9 parts of a bactericide, 10-14 parts of a filler, and 12-16 parts of a fire retardant. The corrosion resistant ethylene propylene diene monomer rubber provided by the invention has the advantages of low raw material price, simple making process, good corrosion resistant effect of the prepared ethylene propylene diene monomer rubber and long service life.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a corrosion-resistant EPDM rubber. Background technique [0002] EPDM (Ethylene Propylene Diene Monomer) is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It is a kind of ethylene propylene rubber. Composition, only contains unsaturated double bonds in the side chain, so it has excellent aging resistance such as ozone resistance, heat resistance, and weather resistance, and can be widely used in automotive parts, waterproof materials for construction, wire and cable sheaths, heat-resistant hoses, tapes , Automotive seals and other fields. However, at present, EPDM rubber still has the problem of poor corrosion resistance. When it is used in a highly corrosive place, it will quickly corrode and fade, seriously affecting the service life and poor economic benefits, which greatly restricts its further development. development and applicati...
