Abstract

The invention discloses a high-strength acrylate adhesive for an automobile and a preparing method and application of the high-strength acrylate adhesive. The adhesive comprises, by weight, 100 parts of acrylic rubber, 20-28 parts of natural rubber, 8-14 parts of chloroprene rubber, 24-30 parts of high-abrasion-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 amino chemically bonded silica, 7-11 parts of glass powder, 2.2-2.6 parts of antiager 445, 1.0-1.5 parts of antiager IPPD, 1.4-1.8 parts of antiager NBC, 1.5-2.2 parts of zinc oxide, 1.0-1.3 parts of sodium oleate, 5.4-6.2 parts of sulphur and 1.8-2.4 parts of accelerant DZ. The natural rubber and the chloroprene rubber are combined with the acrylic rubber to be used, and the high-strength acrylate adhesive is suitable for manufacturing an automobile oil seal sealing piece.

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...
