Abstract

The invention discloses a corrosion-resistant terafluoroethylene-propylene rubber/chlorosulfonated polyethylene rubber sealing gasket and a preparation method thereof. The sealing gasket is prepared from the following raw materials: terafluoroethylene-propylene rubber, chlorosulfonated polyethylene rubber, polyether ether ketone, carbon black N330, nano tin dioxide, calcined argil, modified nano ceramic, mica powder, dicumyl peroxide, 2,5-dimethyl-2,5-hexane-di-tert-butyl peroxide, triallyl isocyanurate, an accelerant CZ2-3, an accelerant ZDC (Zinc Diethyl Dithiocarbamate) and the like. According to the method, when the terafluoroethylene-propylene rubber, the chlorosulfonated polyethylene rubber, the polyether ether ketone and other high-molecular materials with the excellent performance of corrosion resistance are compounded and mixed together, the nano tin dioxide, the calcined argil, the modified nano ceramic, the mica powder and other inorganic filling materials capable of improving the corrosion resistance of the rubber are added at the same time. In addition, the modified nano ceramic can be used for improving the mechanical strength, abrasion resistance, oil resistance and the like of the rubber.

Description

technical field [0001] The invention relates to a sealing gasket and a preparation method thereof, in particular to a corrosion-resistant tetrapropylene fluororubber / chlorosulfonated polyethylene rubber sealing gasket and a preparation method thereof. Background technique [0002] With the rapid development of modern hydraulic transmission technology, the sealing problem of hydraulic devices is becoming more and more prominent. Existing sealing materials for hydraulic systems are incompatible with the requirements of equipment in terms of corrosion resistance and service life to varying degrees, and are far from meeting the actual needs. Therefore, it is urgent to develop a corrosion-resistant rubber sealing material. Contents of the invention [0003] The object of the present invention is to provide a corrosion-resistant tetrapropylene fluororubber / chlorosulfonated polyethylene rubber gasket and a preparation method thereof for the deficiencies of the prior art.
