Problems solved by technology

[0011] The rubber is characterized by small compression permanent deformation, excellent heat resistance, and good processing performance, but biogasoline (bio-ethanol is the mainstream, and about 95% of ethanol production is bio-ethanol) can easily penetrate into the rubber to make it swell , resulting in interdiffusion of molecules, which in turn changes the network structure of vulcanized rubber, resulting in a decrease in the strength and other mechanical properties of the rubber

Abstract

The invention relates to a biofuel oil-resistant fluorine rubber composition. The biofuel oil-resistant fluorine rubber composition consists of the following raw materials in parts by weight: 100 parts of DAI-ELG-902 fluorine rubber, 1-2 parts of 2,5-ditertbutyl peroxide-2,5-methylhexane, 2-5 parts of TAIC triallyl isocyanurate, 15-30 parts of N990 thermal cracking process carbon black, 1.5 parts of WS-2801 and 3-6 parts of L-5FPTFE powder. The biofuel oil-resistant fluorine rubber composition is high in tolerance under a use environment of the biofuel oil and wide in applicable engine range, and has market potential under the widespread condition of the biofuel oil in the future.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a biofuel oil-resistant fluororubber composition. Background technique [0002] With the continuous rise of global oil prices and energy shortages, biofuels have attracted widespread attention from countries all over the world due to their advantages such as less pollution, renewable, and low prices. Raw materials for biofuels such as sweet sorghum, cassava, and sugar cane are more common and cheaper than oil shortages and rising prices. Countries hope to respond to the increasingly serious energy crisis with new fuel forms, and to develop new energy sources with cheaper and more accessible resources. [0003] Due to the advantages of readily available raw materials, low price, less pollution, no unpleasant smell, and renewable, biofuels have become the research and development focus of countries around the world as alternative fuels for petroleum. Listed below: [...
