Abstract

The invention discloses a rubber formula and a preparation method thereof. The rubber formula comprises the following raw materials in part by weight: 10-90 parts of acrylic rubber, 10-90 parts of nitrile rubber, 2-6 parts of zinc oxide, 0.5-3 parts of stearic acid, 0.5-3 parts of p-phenylenediamine antioxidant, 30-65 parts of high wear resistant carbon black, 20-75 parts of semi-reinforcing carbon black, 0.2-1 part of sulfur, 0.2-0.8 part of accelerant, 0.5-2 parts of potassium stearate and 1.5-4 parts of sodium stearate, wherein the sum of parts by weight of the acrylic rubber and the nitrile rubber is 100. The preparation method comprises the steps as follows: rolling crude rubber, mixing the rubber and adding a vulcanization system. The rubber prepared by the rubber formula has the advantages of good overall performance and higher mechanical property, oil resistance, high temperature resistance and the like, and is low in cost and suitable for producing an oil resistant sealing element product resistant to the high temperature of 150 DEG C, such as an automobile transmission oil seal gasket; and the preparation method is simple and cannot cause the phenomenon of roll banding or roll release.

Description

technical field [0001] The invention relates to the technical field of rubber manufacturing, in particular to a rubber formula and a preparation method thereof. Background technique [0002] With the development of modern automobile and machinery industry, the demand for heat-resistant and oil-resistant rubber seal products is becoming more and more urgent, and the technical requirements are getting higher and higher. There are many automobile manufacturers and machinery factories that require rubber seals to be used for a long time at a temperature of 150°C. Acrylate rubber can solve the problem of high temperature resistance, but the cost of a single acrylate rubber is high, and it is easy to stick to the roll or fall off the roll during mixing, and it is difficult to mix. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a rubber formula and a preparation method thereof. The rubber has good high temperature resistanc...
