Embodiment

[0010] Embodiment: The present invention provides a specific embodiment of an anti-ultraviolet TPE plastic formula, which includes the following ingredients in parts by weight: 15-25 parts of SEBS, 1-10 parts of SBS, 30-40 parts of white oil, 0.1 parts of anti-ultraviolet agent -2 parts, 0.1-2 parts of antioxidant, 10-25 parts of calcium carbonate, 10-25 parts of PP, 0.1-1 part 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 Copolymer, without unsaturated double bonds, has good stability and aging resistance.

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

[0013] PP has high impact resistance, mechanical properties and toughness, resists a variety of org...

Abstract

The invention discloses a formula of ultraviolet-resistant TPE (Thermoplastic Elastomer) plastics. The formula contains the following ingredients in parts by weight: 15-25 parts of SEBS, 1-10 parts of SBS, 30-40 parts of white oil, 0.1-2 parts of anti-ultraviolet agent, 0.1-2 parts of antioxidant, 10-25 parts of calcium carbonate, 10-25 parts of PP and 0.1-1 part of zinc stearate. The TPE plastics prepared by adopting the formula are cheap, environment-friendly and ultraviolet-resistant, are high in yield and excellent in properties and meet different requirements of customers.

Description

technical field [0001] The invention relates to an anti-ultraviolet TPE plastic formula. 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 the territory th...
