Abstract

The invention discloses a high temperature resistant and thermal tear resistant fluororubber material and a preparation method thereof. The high temperature resistant and thermal tear resistant fluororubber material is prepared from the ingredients, in parts by weight: 100-150 parts of raw rubber, 1-3 parts of bisphenol AF, 0.1-1 part of accelerant, 20-30 parts of oxide, 10-20 parts of carbon black, 1-3 parts of stearic acid, 0.1-0.5 part of Sulphur, 2-5 parts of resin material, 0.4-0.9 part of fiber material, 0.5-0.7 part of anti-ageing agent, 0.2-0.6 part of stabilizer and 1-3 parts of catalyst. The raw rubber is prepared from vinylidene fluoride, tetrafluoroethylene, perfluoromethyl vinyl ether and a hexafluoropropylene terpolymer. The resin material is prepared from polyethylene resin,ABS resin and ceramic resin. The fiber material is prepared from spandex fiber, glass fiber and polyester fiber. Through the preparation technology, the selected raw materials and the new processingtechnology can make the prepared fluororubber has the outstanding high temperature resistance and thermal tear resistance, and the yield of vulcanization demolding of fluororubber finished products isimproved.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, in particular to a fluororubber material with high temperature resistance and thermal tear resistance. Background technique [0002] Fluorine rubber refers to a synthetic polymer material containing fluorine atoms on the carbon atoms of the main chain or side chain. Therefore, fluorine rubber has excellent oil resistance, chemical corrosion resistance, and weather aging resistance. Therefore, fluorine rubber can be widely used in medical treatment and life. , industry and other fields. Chinese patent CN 103602011B discloses "an oil-resistant rubber", adding carbon black, white carbon black, anti-aging agent, paraffin, light calcium carbonate, stearic acid, zinc oxide, oxidized Magnesium, 2,2'-dithiodibenzothiazole, coumarone and vulcanizing agent make it oil resistant, air tight and high temperature resistant. [0003] Specifically, fluororubber is widely used in the engine oil seal in...
