High temperature resistant and low-cost ethylene propylene rubber

Abstract

The invention discloses high temperature resistant and low-cost ethylene propylene rubber which comprises the following components in parts by weight: 10-30 parts of ethylene propylene monomer, 10-20 parts of ethylene propylene diene monomer, 3-6 parts of a vulcanizing agent, 5-8 parts of zirconium oxide, 6-10 parts of polyamide wax micro powder, 10-12 parts of acetylene carbon black, 2-4 parts of nano attapulgite and 3-5 parts of engine oil. According to the invention, the ethylene propylene monomer and ethylene propylene diene monomer are simultaneously adopted, and enabled to be subjected to co-vulcanization through adjusting a vulcanization system, so that the requirement of high temperature resistance is satisfied, the rubber material has relatively low compression set, the vulcanizate has excellent heat resistance, chemical stability and effect of low compressive deformation, and white carbon black and phenolic resin are adopted, so that the processing fluidity of the rubber material is improved.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an ethylene-propylene rubber with high temperature resistance and low cost. Background technique [0002] With the continuous development of the rubber industry, the use conditions of rubber products are becoming increasingly harsh, and higher requirements are put forward for heat resistance. Many rubber products such as rubber tubes and seals require long-term high temperature resistance of 150 °C. Ethylene propylene rubber has outstanding heat resistance, superheated steam resistance, ozone resistance, weather aging resistance and high insulation performance, especially good heat aging resistance, but the traditional vulcanization system ethylene propylene rubber generally has a temperature resistance of 125 ℃, When the temperature reaches 150°C, the compression deformation of the rubber product will increase accordingly, so that it cannot work normally, causing qualit...
