Abstract

The invention discloses a low-friction butylbenzene / natural rubber composite material and a preparation method thereof, and belongs to the technical field of rubber materials and preparation methods thereof. The low-friction butylbenzene / natural rubber composite material comprises the following components in percentage by weight: 27-32% of butylbenzene, 10-15% of natural rubber, 25-30% of fast-extruding carbon black, 5-10% of high-wear-resistant carbon black, 1.5-3.5% of zinc oxide, 0.6-0.9% of stearic acid, 0.3-0.7% of 4,4'-bis(phenylisopropyl)diphenylamine, 0.3-0.7% of an antioxidant 4010NA, 0.3-0.6% of an accelerant CZ, 0.1-0.4% of an accelerant TT, 0.8-1.2% of sulfur, 1.5-3.5% of a lubricant STRUKTOL TR121, 1.0-3.0% of a physical peptizer RF-50 and a lubricant, 5-10% of graphite F1 and 5-10% of aromatic hydrocarbon oil. By using the butylbenzene / natural rubber composite material, the frictional coefficient of a rubber material can be greatly reduced, so that the service life of rubber parts is prolonged and the assembly production efficiency of the rubber parts is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber materials and preparation methods thereof, more specifically, relates to a low-friction styrene-butadiene / natural rubber combined material and a preparation method thereof, which is a method for reducing the friction between rubber parts and assemblies during assembly and use. Abrasion generated by friction during the process, thereby improving the service life of rubber parts and the rubber material and its preparation method of assembly production efficiency. Background technique [0002] Rubber is a kind of polymer compound with high elasticity. Its molecular chain can be cross-linked. When the cross-linked rubber is deformed by external force, it has the ability of rapid recovery, and has good physical and mechanical properties and chemical stability. The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rub...
