High-performance fluorine rubber gasket and manufacturing method thereof

Abstract

The invention discloses a high-performance fluorine rubber gasket. The high-performance fluorine rubber gasket comprises, by weight, 40-80 parts of binary fluorine rubber, 20-30 parts of silane-modified fluororubber, 12-20 parts of atomized carbon black, 5-10 parts of barium sulfate, 5-15 parts of calcium hydroxide, 1-5 parts of calcium titanate, 1-3 parts of chelate titanate coupling agents, 2-6 parts of molybdenum disulfide, 2-6 parts of phenyl methylpolysilicone resin, 1-2 parts of magnesium oxide, 1-3 parts of dicumyl peroxide, 0.5-1.2 parts of dibenzothiazyl disulfide, 0.5-1.2 parts of triallyl isocyanurate, 1-1.8 parts of bisphenol A, 1-3 parts of hexafluoride isopropylidene diphenol, 1-3 parts of benzyl triphenyl phosphoric chloride, 1-2 parts of sodium stearate, 1-3 parts of palm wax, 1-3 parts of fluorinated polyamide and 1-2 parts of fatty alcohol. The invention further discloses a manufacturing method of the high-performance fluorine rubber gasket. The compression deformation and high-temperature steam resistance of the fluorine rubber gasket are excellent, and the manufacturing method is simple.

Description

technical field [0001] The invention relates to the technical field of fluororubber gaskets, in particular to a high-performance fluororubber gasket and a preparation method thereof. Background technique [0002] In the rubber industry, fluorine rubber has excellent resistance to high temperature, oil, various strong acids and alkalis and chemical corrosion, and is resistant to ozone and radiation. At present, fluorine rubber has been widely used in military aerospace, petrochemical, machinery manufacturing, construction engineering, instrumentation and automobile manufacturing and other fields. The special performance of fluororubber is determined by the structural characteristics of fluorine atoms in its molecules, but it is precisely because of this structural characteristic that it also brings deficiencies in the performance of fluororubber. At present, the compression permanent deformation and high temperature resistance of fluororubber Steam performance is not up to t...

The special performance of fluororubber is determined by the structural characteristics of fluorine atoms in its molecules, but it is precisely because of this structural characteristic that it also brings deficiencies in the performance of fluororubber. At present, the compression permanent deformation and high temperature resistance of fluororubber Steam performance is not up to the requirements of some special cases
