Problems solved by technology

[0014] However, the shoe material made of the thermoplastic elastomer shoe material masterbatch has insufficient tensile strength, insufficient adhesion, poor tensile strength, insufficient wear resistance, poor anti-slip performance, high hardness, poor resilience, and no rubber texture. In terms of usage, it is only suitable for insoles, not for outsoles
[0015] The thermoplastic elastomer is actually a kind of EVA modified body. Its compression is high, its elastic performance is not even as good as EVA, and its application range is narrow. become worse, and the production process is complicated, and the product is a disposable material that cannot be recycled

Abstract

The invention relates to TPE (thermoplastic elastomer) foamed master batch and a preparation method thereof and belongs to the field of new chemical materials. The TPE foamed master batch is prepared from raw materials in parts by weight as follows: 10-30 parts of a styrene-butadiene block copolymer, 10-30 parts of an ethylene-octylene block copolymer, 30-80 parts of white oil, 20-80 parts of a microsphere foaming agent, 10-50 parts of a chemical foaming agent, 1-3 parts of a lubricating agent and 1-3 parts of a dispersing agent. The prepared TPE foamed master batch has high modulus, fine and uniform foam holes and adjustable density.

Description

technical field [0001] The invention relates to a thermoplastic elastomer TPE foam masterbatch and a preparation method thereof, belonging to the field of new chemical materials. Background technique [0002] Thermoplastic elastomer (Thermoplasticlastomer, TPE) is usually an elastic material with a low elastic modulus, which can be repeatedly stretched to more than twice its original length at room temperature, and has the ability to almost completely return to its original length after stress relief. ability. [0003] Thermoplastic elastomer TPE is a kind of rubber with high elasticity, high strength, high resilience, and has the characteristics of injection molding processing. It is environmentally friendly, non-toxic and safe, with a wide range of hardness, soft touch, weather resistance, fatigue resistance and temperature resistance. It can be re-injected, coated and bonded with PP, PE, PC, PS, ABS and other base materials, or molded separately. At present, thermoplast...
