Embodiment 1

[0025] A kind of environment-friendly TPE, its composition and parts by weight are as follows:

[0026]

[0027]

[0028] The preparation method of environment-friendly TPE as mentioned above, the steps are as follows:

[0029] ⑴ Pour SEBS into the mixer;

[0030] ⑵ Pour the white mineral oil into the blender, stir for 10-15 minutes, and stir evenly;

[0031] (3) Pour the rest of the other raw materials into the blender together, and stir for another 10-15 minutes to obtain a well-stirred raw material mixture;

[0032] (4) Pour the evenly stirred raw material mixture into a twin-screw extruder, melt and extrude at 150-200°C, cool, and granulate to obtain an environmentally friendly TPE.

Abstract

The invention relates to environmental-friendly TPE. The TPE comprises following components by weight: 105-110 parts of SEBS, 50-300 parts of mineral oil, 50-150 parts of polypropylene (PP), 50-90 parts of polyurethane, 10-50 parts of EVA, 10-80 parts of calcium carbonate, 0.5-2.5 parts of calcium stearate, 10-15 parts of talcum powder, 1-15 parts of ethylene propylene diene monomer, 1-10 parts of titanium dioxide, 0.2-1 part of an antioxidant and 3.5-4.5 parts of maleic anhydride grafted polypropylene. The TPE is low in cost, convenient to manufacture, good in toughness, high in plasticity, not liable to volatile when being heated, recyclable, and capable of being circulated and reutilized, and capable of largely saving the cost and saving energy. The TPE has a function of environment protection, and has important meaning for sustainable development.

Description

technical field [0001] The invention belongs to the technical field of production and processing of polymer modified materials, in particular to an environment-friendly TPE (thermoplastic elastomer). Background technique [0002] TPE (Thermoplastic Elastomer, Thermoplastic Elastomer) is a material that has the high elasticity, high strength, and high resilience of rubber, and has the characteristics of injection molding. It is environmentally friendly, non-toxic and safe, has a wide range of hardness, excellent colorability, soft touch, weather resistance, fatigue resistance and temperature resistance, excellent processing performance, no need for vulcanization, can be recycled to reduce costs, and can be used for secondary injection molding. It can be coated and bonded with PP, PE, PC, PS, ABS and other base materials, and can also be formed separately. Thermoplastic elastomers have both the processing properties of thermoplastics and the physical properties of vulcanized ...
