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...
