Embodiment

[0010] Embodiment: The present invention provides a specific embodiment of a TPE plastic formula, which includes the following ingredients in parts by weight: 15-30 parts of SEBS, 20-30 parts of SBS, 30-40 parts of rubber oil, 10-20 parts of polypropylene , 0.2-0.5 parts of zinc stearate.

[0011] 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.

[0012] SBS (Styrene-Butadiene-Styrene) has good tensile strength, high surface friction coefficient, good low temperature performance and good processability.

Abstract

The invention discloses a TPE (thermoplastic elastomer) plastic formula and a preparation method thereof. The plastic comprises the following components in parts by weight: 15-30 parts of SEBS (styrene ethylene butylene styrene), 20-30 parts of SBS (styrene butadiene styrene), 30-40 parts of rubber oil, 10-20 parts of polypropylene and 0.2-0.5 part of zinc stearate. A TPE plastic prepared by adopting the formula is cheap, has high yield and excellent performances, meets different requirements of customers and is environment-friendly.

Description

technical field [0001] The invention relates to a TPE plastic formula and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the enhancement of human awareness of environmental protection and the continuous improvement of product requirements, people's demand for high-demand plastics is increasing. 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. Excellent processing performance, can be recycled, coated and bonded with PP, PC, PS, ABS and other base materials, or can be formed separately. TPE has both the processing performance of thermoplastics and the physical properties of vulcanized rubber. It can be called a plastic Combining the advantages of rubber and rubber, it is aggressively occupying t...
