Abstract

The invention discloses a high-abrasion-resistance hydraulic sealing gasket and a preparation method thereof. The high-abrasion-resistance hydraulic sealing gasket is prepared from nitrile-butadiene rubber, ethylene propylene diene monomer, EVA (ethylene-vinyl acetate) resin, epoxy octyl stearate, terpene resin, diphenyl toluene phosphate, organic montmorillonite, modified nano ceramic, cerium oxide, gadolinium oxide, zinc oxide, barium stearate, calcium stearate, titanium white, nano bauxite and other raw materials. By performing organic composite modification with nano aluminum nitride, nano titanium carbide, nano zirconium boride and many types of nano ceramic powder, the compatibility with rubber can be enhanced; and when being used for filling a modified rubber material to prepare the sealing gasket, the modified nano ceramic powder can obviously enhance the heat resistance, abrasion resistance, mechanical strength and other properties of the sealing gasket. The rare-earth metal oxides (cerium oxide and gadolinium oxide) are added to enhance the aging resistance of the rubber.

Description

technical field [0001] The invention relates to a sealing gasket and a preparation method thereof, in particular to a high wear-resistant hydraulic 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. The existing sealing materials for hydraulic systems are incompatible with the requirements of equipment in terms of wear resistance and service life to varying degrees, which are far from meeting the actual needs. Therefore, it is urgent to develop a high wear resistance hydraulic seal material. Contents of the invention [0003] The object of the present invention is to provide a high-wear-resistant hydraulic sealing gasket and a preparation method thereof for the deficiencies of the prior art. [0004] The technical scheme that the present invention adopts is as follows: [0005] A high wear-resis...
