Abstract

The invention belongs to the technical field of rubber materials, and particularly relates to a preparation method of an automobile pipeline rubber material. The preparation method comprises the steps of S1, preparing the following raw materials in parts by weight: 60-100 parts of fluororubber, 1-2 parts of high wear-resistant carbon black, 40-50 parts of semi-reinforced carbon black, 2-6 parts of zinc oxide, 4-6 parts of magnesium oxide, 0.5-1 part of an anti-aging agent, 2-6 parts of an accelerant, 1-4 parts of stearic acid, 1-2 parts of an antioxidant and 2-4 parts of a vulcanizing agent. Through introduction of fluorine atoms in the fluororubber, the rubber is endowed with excellent heat resistance, oil resistance and corrosion resistance, the wear resistance of the rubber can be enhanced through the high-wear-resistance carbon black, the overall strength of the rubber is guaranteed through the semi-reinforcing carbon black, magnesium oxide and zinc oxide mainly play a role in fluidity and oxidation resistance in the rubber, the tensile strength and the impact resistance of the rubber are improved, the anti-aging agent can improve the thermal oxygen aging resistance of the rubber, and the accelerant can promote the reaction between the rubber and the vulcanizing agent, so that the vulcanization reaction speed is increased.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a method for preparing rubber materials for automobile pipelines. Background technique [0002] With the high performance of automobiles and the rapid development of the rubber industry, water pipes are an important part of automobiles, and the requirements for rubber products of automobile water pipes are also increasing. Due to the requirements of the use environment and working conditions, the outer rubber usually needs to have Good mechanical properties, heat resistance and aging resistance. [0003] It is found in the use of existing automobile water pipes that the mechanical properties, heat resistance and aging resistance of the existing automobile water pipe outer rubber are poor, and it is difficult to meet the standard requirements of automobile water pipes. Therefore, the invention provides a rubber pipe for automobiles The method of preparation of the materi...
