Embodiment Construction

[0009] The present invention will be described in detail below through specific examples.

[0010] A new type of oil-resistant gasket material, made of the following raw materials in parts by weight (kg): 45 fluorine rubber, 20 nitrile rubber, 20 SG-5 type PVC resin, 5 acetyl triethyl citrate, 2 zinc oxide, phthalic anhydride 1. Zinc chromate 2, sulfur 1, magnesium oxide 2, accelerator DTDM1, isooctyl dithioglycolate di-n-octyl tin 1, crosslinking agent TAIC1, zinc stearate 1, semi-reinforcing carbon black 30, modified bump stick clay 10;

[0011] The modified attapulgite is made of the following raw materials in parts by weight (kg): attapulgite 20, toluene diisocyanate 3, trimethylolpropane triacrylate 2, barley oil 2, citric acid 2, nano titanium dioxide 1 , aluminum oxide 2, methyltriethoxysilane 1, accelerator TMTM1, corundum powder 2, pepper seed oil 1; the preparation method is to put attapulgite into a calciner at 700-720°C for 3- 4 hours, cool, soak in 10-12% hydroc...

Abstract

The invention discloses a novel oil-resistant sealing pad material. The novel oil-resistant sealing pad material is prepared from the following material in parts by weight: 45-50 parts of fluororubber, 20-25 parts of nitrile rubber, 20-25 parts of SG-5 type PVC (Polyvinyl Chloride) resin, 5-8 parts of acetyl triethyl citrate, 2-3 parts of zinc oxide, 1-2 parts of phthalic anhydride, 2-3 parts of zinc chromate, 1-2 parts of sulfur, 2-3 parts of magnesium oxide, 1-2 parts of an accelerant DTDM (Dithiodimorpholine), 1-2 parts of di-n-octyl tin dimercaptoiso-octyl acetate, 1-2 parts of a cross-linking agent TAIC (Triallyl Isocyanurate), 1-2 parts of zinc stearate, 30-35 parts of semi-reinforcing carbon black and 10-12 parts of modified attapulgite clay. According to the invention, the modified attapulgite clay is added, so that process performances of the rubber material are improved; and an environment-friendly compounding agent is used, so that toxic or side effect and pollution to environment are reduced. According to the novel oil-resistant sealing pad material and the preparation method disclosed by the invention, formula is reasonable, cost is lowered, process is simple, and oil resistance and insulativity are good.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a novel oil-resistant gasket material and a preparation method thereof. Background technique [0002] Gasket is a material used for sealing inside machinery, equipment, pipelines, etc. The gaskets currently used are mostly rubber gaskets, which are characterized by high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance, fuel oil resistance, lubricating oil resistance, strong oxidant resistance, chemical resistance and good electrical insulation performance. Widely used in defense industry and civilian industry. However, 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 researching and developing a kind of high-performance rubber gasket has become the task of top priority. Nitrile rubber has ex...
