Abstract

The invention discloses a medium corrosion-resistant fluorubber sealing gasket and a production method thereof. The sealing gasket is produced from, by weight, 30-50 parts of perfluoroether rubber, 20-40 parts of chloroprene rubber, 4-8 parts of bisphenol AF, 6-9 parts of white factice, 2-4 parts of thioisobutyramide, 19-33 parts of cancrinite powder, 12-24 parts of asbestos wool, 4-5 parts of diperoxocarbamate, 15-20 parts of colloid graphite powder, 3-5 parts of tetraethylammonium chloride, 7-11 parts of C5 petroleum resin, 4-6 parts of 1,2,3,4,5-pentachlorobibenzene, 20-30 parts of carbon black N990, 2-3 parts of 2,2'-methylenebis(4-ethyl-6-tert-butyl phenol), 1-2 parts of N-phenyl-2-naphthylamine and 15-20 parts of a modifier. The sealing gasket produced in the invention has the advantages of very protruding medium corrosion resistance, resistance to oil, acids, alkalis, salts, ethers, alcohols, water vapor and other corrosive media, and excellent wear, ageing and high temperature resistance.

Description

technical field [0001] The invention relates to a rubber sealing gasket, in particular to a medium corrosion resistant fluorine rubber sealing gasket and a preparation method thereof. Background technique [0002] Fluorine rubber (fluororubber) refers to a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain. The introduction of fluorine atoms endows rubber with excellent heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance, and has been widely used in the field of sealing materials. With the rapid development of science and technology and industry, the performance requirements of fluororubber sealing materials are getting higher and higher. The existing fluororubber gaskets on the market have the disadvantage of poor corrosion resistance to medium, which leads to their short service life and cannot meet the needs of the market. demand.
