Abstract

The invention relates to an EVA wear-resistant and flame-retardant elastomer material, which consists of 28.6-51.6wt% ethylene-vinyl acetate copolymer, 0-15wt% polyethylene or 0-15wt% polypropylene, 25-35wt% anti-wear agent, 10-20wt% flame retardant and 2.4-8.4wt% other modified additives, wherein, other modified additives are antioxidants, compatibilizers and toughening agents The preparation method is to mix ethylene-vinyl acetate copolymer, polypropylene or polyethylene, wear-resisting agent, flame retardant and modification additives uniformly through a high-speed mixer, and then pass through The wear-resistant and flame-retardant elastomer material and its molded products are prepared by melting and blending in an internal mixer or a twin-screw extruder. The invention has better hand feel and comfort, and has higher commercial value in the fields of floors, walls, and automotive interiors. It can improve the yield of materials in the molding process by recycling defective products. Compared with rubber or The preparation of similar materials from PVC is simpler and more convenient, with less investment in equipment.

Description

technical field [0001] The invention belongs to the technical field of production of thermoplastic elastomer materials, and in particular relates to a novel wear-resistant and flame-resistant elastomer material and a preparation method thereof. Background technique [0002] The thermoplastic elastomer based on EVA material not only has the high elasticity of rubber, but also has the characteristics of injection molding processing. At the same time, the addition of wear-resistant agents, flame retardants and other processing aids makes the material have high wear resistance. And better flame retardancy, so that the material has greater advantages in application. [0003] Ethylene-vinyl acetate copolymer (EVA) is formed by bulk polymerization of ethylene and vinyl acetate at a certain temperature and high pressure. It is a polymer composed of polymerized molecules with different chain lengths and chain structures. The main performance of ethylene-vinyl acetate copolymer (EVA)...
