Abstract

The invention provides a heat-resistant rubber material. The heat-resistant rubber material comprises the following components in parts by weight: 50-70 parts of styrene butadiene rubber, 30-50 parts of EPDM (ethylene propylene diene monomer) rubber, 10-30 parts of butadiene rubber, 8-15 parts of zinc oxide, 1-3 parts of stearic acid, 4-8 parts of an antioxidant, 3-8 parts of an antiager, 1-5 parts of an accelerant, 40-55 parts of high-wear resistance carbon, 4-8 parts of petroleum resin, 3-6 parts of calcium carbonate and 1-5 parts of a vulcanizing agent. The heat resistance and the mechanical strength of the heat-resistant rubber composition provided by the invention are significantly improved, so that the problem that the service life is greatly shortened in a high-temperature operating environment is solved; under the coaction of the antiager and a vulcanizing system, the heat aging resistance of the blend rubber is greatly improved.

Description

technical field [0001] The invention belongs to the field of polymers, and in particular relates to a heat-resistant rubber material. Background technique [0002] Rubber is an elastic polymer. Rubber can be obtained from some plant values, or it can be man-made, both of which can be used in a wide range of applications, such as tires, gaskets, and so on. Rubber is divided into natural rubber and synthetic rubber according to raw materials. However, the rubber with a single component has a single performance and cannot meet the increasingly high requirements of modern life. Therefore, compound formulations are needed to meet the requirements. [0003] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machiner...
