Abstract

The invention relates to the technical field of preparation of acrylate rubber, and discloses a synthesis method of non-corrosive acrylate rubber. The synthesis method of the non-corrosive acrylate rubber comprises the following steps: S1, preparation of materials; S2, primary mixing; S3, secondary mixing; S4, melting and mixing; and S5, vulcanization and shaping. Compared with a traditional TCY vulcanization system, the method of the invention has the advantages that a vulcanization speed is higher, a mold cannot be corroded, and the service life of the mold is effectively prolonged; and since methyl acrylate rubber, ethyl acrylate rubber and diene rubber serve as raw materials, and the diene rubber is high in stability, so the heat resistance, the tensile strength, the hardness and the oil resistance of the acrylate rubber can be effectively improved, the phenomenon of roller sticking caused by excessive softness and excessive adhesion during rubber mixing can be avoided, the low temperature resistance of the acrylate rubber is enhanced to a certain extent, practical performance is improved, a production process is simpler, and production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of acrylate rubber preparation, in particular to a method for synthesizing non-corrosive acrylate rubber. Background technique [0002] Acrylate rubber is an elastomer obtained by copolymerization of 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. [0003] The existing acrylate rubber also has some disadvantages: it is highly corrosive to the processing mold, which shortens the service life of the processing mold; the processability of the roller is poor, and the phenomenon of sti...
