Abstract

The invention belongs to the field of organic compound processing, and provides a mixture for automobile high-speed rotation oil seals, which is prepared from the following components in parts by weight: 100 parts of fluororubber, 1.5-2.5 parts of bisphenol AF, 0.4-0.8 part of accelerator BPP, 2-5 parts of active magnesium oxide, 4-10 parts of calcium hydroxide, 0-50 parts of carbon black, 5-50 parts of calcium silicate, 0-50 parts of hexagonal boron nitride, 0-20 parts of carbon nanotube and 1-3 parts of mold release agent. By adopting the fluororubber F246 (the Mooney viscosity is 100-150) as the base unvulcanized rubber and optimizing the formula system, the physical and mechanical properties of the vulcanized fluororubber of the original formula are basically unchanged. The two different types of heat-conducting fillers are compounded to enhance the heat conductivity coefficient of the compounded rubber under the synergic actions, and the heat-conducting property of the vulcanized rubber product for manufacturing is obviously enhanced.

Description

technical field [0001] The invention belongs to the processing field of polymer compounds, and in particular relates to a rubber compound for vulcanization. Background technique [0002] Viton was developed in the 1950s to meet the needs of the aviation industry for high-performance sealing, and was quickly applied to the automotive industry, chemical industry and other fields. According to foreign statistics, the amount of fluorine rubber used in the automobile industry accounts for more than 60% of the world's total fluorine rubber, and the rapid development of the automobile industry has also driven the fluorine rubber industry. Fluorine rubber has the characteristics of high temperature resistance, oil resistance and solvent resistance, and good physical and mechanical properties, especially the outstanding high temperature and low pressure denaturation performance, making it the preferred material for automotive oil seals. [0003] The thermal conductivity of fluorine ...
