Abstract

The invention mainly relates to an acrylate rubber material, a preparation method and an application thereof. The described acrylate rubber material is mainly prepared from the following raw materials in parts by weight: 90-110 parts of modified active chlorine-type acrylate, 60-85 parts of reinforcing agent, 1-3 anti-aging agent and 3.3-4.2 vulcanizing agent; wherein , the acrylate rubber material is subjected to secondary vulcanization, and the time of the secondary vulcanization is 6-8h. The acrylate rubber material of the invention has excellent processing performance, is easy to release the product, has a wide range of use temperature, can be used at -35-150°C, has good lubricating oil resistance, small loss of tensile performance, small volume change, and compression deformation. Small, and meet the compression deformation of Volkswagen PV3307, and the cost is low, which is conducive to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to an acrylic rubber material, a preparation method and an application thereof. Background technique [0002] The oil pan gasket is installed between the oil pan and the gearbox, and produces resilience after being deformed by rubber extrusion, eliminating the gap after installation, and generating sealing contact pressure on the surface of the required sealing area, thereby preventing the internal lubrication of the gearbox The oil leaks outward, because the working temperature can reach 150°C, and the cost of fluorine rubber and ethylene acrylate is high, so ACM acrylate is the best choice. [0003] The structure of the oil pan gasket is relatively complex, and the processing performance of ACM acrylate is poor, and it is prone to problems such as flow marks and mold dirt. As a leader in the automotive industry, Volkswagen has its own performance requirements for rubbe...
