Abstract

The invention provides a low compression set active chlorine type acrylate rubber and a preparation method thereof, belonging to the technical field of synthetic rubber. A low compression set active chlorine type acrylate rubber, its raw materials include by weight fraction: 100 parts of active chlorine type acrylate rubber, 20-100 parts of reinforcing agent, 1-5 parts of silane coupling agent, vulcanizing agent 1 ‑3 parts, 1‑5 parts of processing aid and 2‑5 parts of anti-aging agent, the reinforcing agent includes fast extruded carbon black and precipitated silica, the mass ratio of fast extruded carbon black and precipitated silica is 1:1 . The active chlorine-type acrylate rubber not only has good low compression set performance, but also has good thermal stability, high hardness and high tensile strength. A method for preparing low compression set active chlorine-type acrylate rubber. The silane coupling agent is added when the temperature of the rubber mixture is 50-70°C. The method is simple, and the prepared active chlorine-type acrylate rubber has better properties .

Description

technical field

[0001] The invention belongs to the technical field of compounding and processing of synthetic rubber, and in particular relates to a low compression set active chlorine type acrylate rubber and a preparation method thereof. Background technique

[0002] Acrylate rubber (ACM) is a kind of elastic material formed by the copolymerization of acrylate and monomers that can provide cross-linking reactive groups. Its main chain is a saturated structure, so it has heat resistance and UV radiation resistance. And ozone resistance; its side chain contains polar ester groups, so it also has excellent oil resistance. The main use of acrylate rubber is to make heat-resistant and oil-resistant seals and oil pipes, etc., mainly used in automobiles, motorcycles, power transformers, ships, petrochemical and other fields.

[0003] Acrylic rubber has relatively large compression permanent deformation, which is a performance defect as a sealing material. Large deformation may ...
