Anti-aging synthetic rubber formula and preparation method thereof

The invention relates to the technical field of synthetic rubber, and discloses an anti-aging synthetic rubber formula and a preparation method thereof, the anti-aging synthetic rubber formula comprises the following raw materials by mass: 50-65 parts of EPDM, 35-50 parts of chlorosulfonated polyethylene, 2-4 parts of a vulcanizing agent, 5-7 parts of melamine resin, 1-3 parts of a softener, 3-5 parts of a filler, 1-3 parts of ointment and 2-4 parts of an anti-aging agent. According to the anti-aging synthetic rubber formula and the preparation method thereof provided by the invention, a vulcanizing machine is added for vulcanizing rubber, so that the processability of a system is improved; by adding the ointment, the plasticity of the rubber is improved; by adding the proper amount of softener, the shrinkage rate of the rubber is reduced, the accuracy of the extruded specification is improved, and the calorific value is reduced; the rubber can have good quality; and the wear resistance and the bending resist
