Abstract

The invention discloses ACM thermoplastic vulcanized rubber and a preparation method and application thereof. The preparation method comprises the following steps of: adding ACM rubber, a polymer, a compatilizer, a vulcanizing agent, an anti-UV agent and an antioxidant into a twin-screw extruder together by a weightless metering scale; the ACM thermoplastic vulcanized rubber is obtained through extrusion, the plasticity of the ACM rubber is improved through addition of the polymer, the rubber blend is subjected to phase inversion in the processing process, the obtained product can be repeatedly used, recycling of leftover materials and waste products is facilitated, the utilization rate of rubber materials is increased, and pollution of solid waste is reduced.

Description

technical field [0001] The invention belongs to rubber technology, and in particular relates to ACM thermoplastic vulcanized rubber and its preparation method and application. Background technique [0002] Acrylate rubber (hereinafter referred to as ACM) is an elastomer obtained by copolymerizing acrylate as the main monomer. Its main chain is a saturated carbon chain and its side groups are polar ester groups. Because of its special structure, it has many excellent characteristics, such as heat resistance, aging resistance, oil resistance, ozone resistance, ultraviolet resistance and so on. The prior art discloses a combined composition of acrylate rubber and ethylene acrylate rubber. The components of the composition are: acrylate rubber, ethylene acrylate rubber, quick extruded carbon black, plasticizer, stearic acid, and internal release agent 18D, anti-aging agent 445, vulcanizing agent DIAK 1#, accelerator diphenyl guanidine; using AEM / ACM together, the tensile streng...
