Abstract

The invention discloses a high-strength acrylate rubber material for automobiles, and a preparation method and application thereof. The rubber material is composed of the following raw materials in parts by weight: 100 parts of acrylate rubber, 20-28 parts of silicic acid rubber, 8-14 parts of chloroprene rubber, 24-30 parts of high-wear-resistance carbon black, 6-10 parts of graphene, 1.2-1.6 parts of butyl stearate, 2.1-2.5 parts of tributyl citrate, 2.0-3.2 parts of aminosilane bonded silica gel, 7-11 parts of glass powder, 2.2-2.6 parts of anti-aging agent 445, 1.0-1.5 parts of anti-aging agent IPPD, 1.4-1.8 parts of anti-aging agent NBC, 1.5-2.2 parts of zinc oxide, 1.0-1.3 parts of sodium oleate, 5.4-6.2 parts of sulfur and 1.8-2.4 parts of accelerator DZ. By compounding the silicic acid rubber, chloroprene rubber and acrylate rubber, the rubber material is suitable for manufacturing automobile oil seals.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a high-strength acrylate rubber compound for automobiles, a preparation method and application thereof. Background technique [0002] Acrylate rubber (hereinafter referred to as ACM) is an elastomer obtained by copolymerizing acrylate as the main monomer. Its main chain is a saturated carbon chain and its side groups are polar ester groups. Due to the special structure endows it with many excellent characteristics, such as: heat resistance, aging resistance, oil resistance, ozone resistance, UV resistance, etc., its mechanical properties and processing properties are superior to fluororubber and silicone rubber, and its heat resistance, aging resistance and oil resistance Superior to nitrile rubber. ACM is widely used in various high-temperature and oil-resistant environments, and has become a sealing material that the automotive industry has focused on developing and prom...
