Embodiment Construction

[0014] A high-strength tear-resistant rubber gasket made of the following raw materials by weight (kg): chlorosulfonated polyethylene rubber (TS-830) 50, silicone rubber (SP-352) 25, bisphenol A polycarbonate Ester 15, cashew nut shell oil modified phenolic resin 10, hexamethylenetetramine 1.5, dicumyl peroxide 2, spray carbon black 18, modified nano ceramics 12, silicon magnesium calcium whisker 8, nano wollastonite 6. Zinc methacrylate 2, magnesium oxide 1.5, stearic acid 2, vinyl silicone oil 4, chlorinated paraffin 6, triethyl citrate 7, vulcanizing agent TRA 2, calcium stearate 1, zinc stearate 2 , accelerator TT 2, accelerator NA-22 1, anti-aging agent NBC 3, anti-aging agent RD 1.

[0015] The preparation method of described modified wollastonite is as follows:

[0016] a. Take the dried wollastonite and crush it to less than 15 μm, put it into a dispersion kettle, add deionized water three times the amount of wollastonite, and then add 2.5% sodium polyacrylate, 1.5% t...

Abstract

The invention discloses a high-strength tear-resistant rubber sealing gasket and a preparation method thereof. The high-strength tear-resistant rubber sealing gasket is prepared from raw materials, namely chlorosulfonated polyethylene rubber, silicon rubber, bisphenol A type polycarbonate, cashew nut shell oil modified phenolic resin, hexamethylenetetramine, dicumyl peroxide, spray carbon black, modified nano ceramics, silicon-magnesium-calcium crystal whiskers, nanometer wollastonite, zinc methacrylate, magnesium oxide, stearic acid, vinyl silicone oil, chlorinated paraffin 4-7, triethyl citrate and the like. According to the high-strength tear-resistant rubber sealing gasket and the preparation method thereof disclosed by the invention, the organic composite modification is carried out by adopting multiple nano ceramic powder, namely nanometer aluminum nitride, nanometer titanium carbide and nanometer zirconium boride, so that the compatibility of the nano ceramic powder and rubber can be enhanced; the modified nano ceramic powder, the silicon-magnesium-calcium crystal whiskers, the nanometer wollastonite and the like are filled in a modified rubber material together to prepare the sealing gasket, so that the mechanical strength, impact resistance and especially tear resistance of the sealing gasket can be remarkably improved; the heat resistance, abrasion resistance and the like of the rubber can also be improved.

Description

technical field [0001] The invention relates to a sealing pad and a preparation method thereof, in particular to a high-strength tear-resistant rubber sealing pad 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 the equipment in terms of mechanical strength, tear resistance, and service life to varying degrees, which are far from meeting the actual needs. Therefore, it is urgent to develop a high Strength tear-resistant rubber gasket. Contents of the invention [0003] The object of the present invention is to provide a high-strength tear-resistant rubber 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 follow...
