Abstract

The invention discloses a method for preparing high-stability automobile rubber tube rubber. The method comprises the following steps: (a) cleaning polytetrafluoroethylene micropowder; (b) carrying out electron beam radiation treatment; (c) soaking with a modification liquid A; (d) preparing a mixed material B; (e) weighing raw materials; and (f) preparing a finished product. The preparation method disclosed by the invention is relatively simple in process, the steps are reasonably matched, properties such as strength, temperature resistance, aging resistance and corrosion resistance of the rubber of the automobile rubber tube are remarkably improved, the stability of the rubber is improved, the service life of the rubber is prolonged, and the rubber has great market competitiveness and production benefits.

Description

technical field [0001] The invention belongs to the technical field of automobile rubber processing, and in particular relates to a preparation method of high-stability automobile rubber hose. Background technique [0002] At present, the rapid and vigorous development of the automobile industry has brought unprecedented development opportunities to the rubber industry supporting the automobile industry. According to the "2015-2020 China Automobile Manufacturing Market Assessment and Investment Prospect Forecast Report" released by China Industry Information Network, it shows that in June 2015, the number of automobiles in my country has exceeded 163 million, second only to the 220 million in the United States. vehicles, becoming the second in the world. China has become a big country of automobile consumption. Correspondingly, the engine manufacturing technology is relatively backward, which is one of the main factors hindering the development of the domestic automobile ind...
