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
The invention belongs to polymer modification material produce processing technique field, especially a kind of environment-friendly type TPE(thermoplastic elastomer).
Background technology
TPE(Thermoplastic Elastomer, thermoplastic elastomer) be a kind of snappiness with rubber, high strength, high resilience, having again can the material of feature of injection molding.There is environment-protecting asepsis safety, durometer level is wide, has excellent tint permanence, soft-touch, weathering resistance, fatigue resistance and temperature tolerance, processing characteristics is superior, need not sulfuration, can recycle and reduce costs, both can secondary injection molding, with body material coating and bondings such as PP, PE, PC, PS, ABS, also can be shaping separately.Thermoplastic elastomer had both had the processing characteristics of thermoplastics, had again the physicals of vulcanized rubber, was the advantageous combination of plastics and rubber advantage.But current TPE mostly can not recycling, not only causes a large amount of wastes of resource, and causes serious pollution to environment, bring detrimentally affect to Sustainable development.
By retrieval, find following several sections of patent publication us relevant to patent application of the present invention:
