Problems solved by technology

TPE (Thermoplastic Elastomer) is a material with high elasticity, high strength and high resilience of rubber, and can be processed by injection molding. It is non-toxic and environmentally friendly, and has excellent colorability, weather resistance and temperature resistance. It has excellent processing performance, can be recycled, and can be coated and bonded with PP, PC, PS, ABS and other base materials, and can also be formed separately. However, the price of this TPE is still high, the yield is low, and it is in urgent need of improvement.

Embodiment

[0008] Embodiment: The present invention provides a specific embodiment of an environmentally friendly TPE plastic formula, which includes the following components by weight: 25-35 parts of SEBS, 20-25 parts of TPU, 5-10 parts of PA66, and 15-25 parts of monomer resin , 5-10 parts of silicone masterbatch, 25-40 parts of white oil.

[0009] SEBS is a linear three-block copolymer with polystyrene as the terminal block and ethylene-butene copolymer as the middle elastic block obtained by hydrogenation of polybutadiene, also known as styrene-ethylene-butylene-styrene block The copolymer does not contain unsaturated double bonds and has good stability and aging resistance. The high molecular SEBS used in the present invention has good tensile force.

[0010] PA66 has excellent wear resistance, self-lubrication, high mechanical strength, and can maintain strong strength and rigidity at relatively high temperatures.

[0011] TPU has good elasticity and compression deformation resist...
