Acrylate rubber material and preparation method thereof and heat-shrinkable bushing

The invention is suitable for the technical field of materials, and provides an acrylate rubber material and a preparation method thereof and a heat-shrinkable bushing. The acrylate rubber material comprises the following raw materials in parts by weight: 60-85 parts of polyacrylate rubber, 5-20 parts of polyvinyl acetate rubber, 10-20 parts of metal ion polymer resin, 1-4 parts of a lubricant, 1-4 parts of an anti-aging agent and 10-30 parts of a reinforcing agent. According to the invention, a polyacrylate rubber material is introduced as a base material and is functionally modified by a polyvinyl acetate rubber and a metal ion polymer resin, so that the obtained acrylate rubber material has excellent oil resistance, high/low temperature resistance and flexibility and is low in cost; and the metal ion polymer resin is used as a thermal shrinkage framework, so that the thermal shrinkage performance can be realized due to cohesive shrinkage internal stress caused by shaping after shock cooling after thermal e
