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.
