Abstract

The invention relates to the field of high polymer materials, and particularly discloses low-temperature-resistant rubber, a preparation method thereof and an air spring end cover applying the low-temperature-resistant rubber. The low-temperature-resistant rubber comprises the following substances in parts by weight: 80-100 parts of rubber, 3-8 parts of zinc oxide, 1-2 parts of a catalyst, 1-2 parts of a lubricant, 5-15 parts of a cold-resistant agent, 60-80 parts of a filler, 2-3 parts of a vulcanizing agent and 0.5-2 parts of a cross-linking aid, wherein the cold-resistant agent is a cold-resistant agent dispersed by a dispersant, and the dispersant comprises EVA and layered kaolin. The preparation method comprises the following steps of: S1, mixing; and S2, vulcanization. The low-temperature-resistant rubber disclosed by the invention can be used for sealing rubber rings, damping materials and life-saving articles, and has the advantage of relatively excellent elastic effect in a low-temperature environment.

Description

technical field [0001] The present application relates to the field of polymer materials, in particular to a low-temperature-resistant rubber, a preparation method thereof, and an air spring end cap using the same. Background technique [0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can deform and quickly return to its original shape. Rubber is widely used in daily life. Rubber can be used to make tires, sealing materials, life-saving supplies, shock-absorbing materials, etc. With the development of technology and fields, the requirements for rubber materials have also increased. In addition to requiring rubber to have high strength In addition to properties such as tear resistance, medium resistance, aging resistance and insulation, it is also required to have good elasticity in cold environments, but at lower temperatures, rubber is prone to vitrification or crystallization, resulting in rubber Poor e...
