Embodiment Construction

[0015] A high wear-resistant rubber gasket made of raw materials with the following weight (kg): Nitrile rubber (N220S) 60、 Butadiene rubber (BR9000 ) 25, ABS high rubber powder 12 , diisobutyl nylon acid Ester 4, lemon Tributyl citrate 3, tricresyl phosphate 5, isooctyl dithioglycolate di-n-octyl tin 1.5, barium stearate 2, zinc oxide 3, magnesium oxide 2, modified barite powder 12, nano silicon carbide 8 、 High wear-resistant carbon black N330 15, 2-mercaptobenzimidazole 1.5, diperoxycarbamate 2, antioxidant DNP 2, accelerator TMTD 1, accelerator TETD 2.

[0016] The preparation method of the modified barite powder is as follows: crush the barite to below 10 μm, then add tree ash equivalent to 5% of the barite weight, 4% tungsten carbide, 3% zirconium fluoride, 4% % polyisobutene, 5% ferrocene, 4% calcium lignosulfonate, mixed and ground at 55°C for 20 minutes, and then sprayed with isopropyl distearyl oxide equivalent to 3% of barite weight base aluminate and 1.5% an...

Abstract

The invention discloses a high-wear-resistance rubber sealing gasket and a preparation method thereof. The high-wear-resistance rubber sealing gasket is prepared from the following raw materials in parts by weight: 50-70 parts of nitrile-butadiene rubber, 20-30 parts of cis-1,4-polybutadiene rubber, 10-15 parts of ABS (acrylonitrile-butadiene-styrene) high rubber powder, 3-5 parts of dibutyl ester of nylon acid, 2-3 parts of tributyl citrate, 4-6 parts of tritolyl phosphate, 1-2 parts of imarcaptoacetate dioctyltin, 1-2 parts of barium stearate, 3-4 parts of zinc oxide, 2-3 parts of magnesium oxide, 10-15 parts of modified barite powder, 5-10 parts of nano silicon carbide, 10-15 parts of high-wear-resistance carbon black N330, 1-2 parts of 2-thiolbenzoimidazole, 2-3 parts of bis-peroxycarbamate, 1-2 parts of anti-aging agent DNP, 1-2 parts of accelerator TMTD and 1-2 parts of accelerator TETD. Tungsten carbide, zirconium fluoride and the like are utilized to inorganically modify barite, thereby obviously enhancing the mechanical strength and wear resistance of the rubber material; and isopropyldistearoyloxy aluminate and the like are utilized to organically modify the barite, thereby enhancing the compatibility of the barite with the rubber material.

Description

technical field [0001] The invention relates to a sealing gasket, in particular to a high wear-resistant rubber sealing gasket and a preparation method thereof. Background technique [0002] Rubber gasket is a material used for sealing inside machinery, equipment, pipelines, etc. It is widely used in the fields of automobiles, electronics, and chemicals. The existing rubber gaskets have defects such as unsatisfactory sealing effect, poor wear resistance and low strength, which are far from meeting the actual requirements. Therefore research and develop a kind of high wear-resisting rubber sealing gasket and become the task of top priority. Contents of the invention [0003] The object of the present invention is to provide a high wear-resistant rubber gasket and a preparation method thereof, the gasket has excellent sealing performance, good wear resistance and high mechanical strength. [0004] The technical scheme that the present invention adopts is as follows: [00...
