Embodiment 1

[0017] Example 1: High temperature resistant rubber sealing ring material, the weight parts (kg) of the raw materials are: styrene-butadiene rubber (Yangzi Petrochemical SBR1712) 100, high wear-resistant white carbon black 32, 2-thiol benzene Imidazole 2.2, accelerator DTDM0.8, aminopropyltriethoxysilane 6.0, resorcinol 2.2, modified clay 3.2, epoxy soybean oil 0.55 and sodium lignosulfonate 1.0.

[0018] The preparation method of high temperature resistant rubber sealing ring material comprises the following steps:

[0019] (1) Preparation of modified clay:

[0020] a: Weigh 11kg of clay, 5kg of calcium fluoride, 3kg of aluminum nitride powder, 4kg of alum powder, and 7kg of white carbon black, mix them evenly and sinter for 2 hours, control the temperature at 600°C, and pulverize for use;

[0021] b: Add the pulverized mixture of the above step (a) into an anhydrous ethanol solution for 4 hours, remove it, and dry it at 52°C;

[0022] c: Add 2.5kg of aminopropyltriethoxysi...

Abstract

The invention discloses a high-temperature-resistant rubber sealing ring material and a preparation method thereof. The rubber sealing ring material is prepared from the following raw materials: butadiene styrene rubber, white carbon black with high abrasion resistance, 2-thiol benzimidazole, an accelerant DTDM (di(morpholin-4-yl) disulphide), aminopropyltriethoxysilane, resorcinol, modified clay, epoxidized soybean oil and sodium lignin sulfonate. The butadiene styrene rubber used as a main material is low in price and good in heat resistance and aging resistance; the modified clay is added into the raw materials, so that the inner bonding force of a rubber sealing ring is enhanced. Thus, the tensile resistance, high-temperature resistance, metal bonding property, mechanical property and the like of the rubber sealing ring are effectively improved.
