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.
