Abstract

The invention discloses a method for preparing a wear-resistant and high-temperature-resistant material and in particular relates to the field of preparation of novel materials. Main materials used inthe method comprise the following raw materials in parts by weight: 80-120 parts of acrylate rubber, 0.8-1.4 parts of stearic acid, 17-25 parts of carbon black, 4-6 parts of zinc oxide, 0.5-1.8 partsof sulfur and 10-20 parts of montmorillonite. The method comprises the following specific processing steps: preparing raw materials, crushing the raw materials, performing refining of a first round,performing refining of a second round, and vulcanizing a blank material. Due to addition of the montmorillonite and optimization of the preparation method, a rubber material of a long service life canbe prepared, and a continuous sealing effect can be ensured; in addition, on premise that the wearing resistance and the high temperature resistance of a composite material are ensured, the tensile strength of the acrylate rubber can be effectively maintained, and the property that damage is not caused by stress deformation of the acrylate rubber when the montmorillonite is added is not changed.

Description

technical field [0001] The invention relates to the technical field of novel material preparation, and more specifically, the invention relates to a method for preparing a wear-resistant and high-temperature-resistant material. 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 o...
