Embodiment

[0010] Embodiment: the present invention provides a kind of specific embodiment of thermoplastic elastomer plastic formula, and it comprises the composition of following parts by weight: SEBS18-25 part, SBS9-12 part, rubber oil 60-65 part, zinc stearate 0.1- 0.5 parts, silicone masterbatch 4-8 parts.

[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.

[0013] Rubber oil is used to improve the properties of rubber such as elasticity, flexibility, ease of ...

Abstract

The invention discloses a thermoplastic elastomer plastic formula which comprises the following components in parts by weight: 18-25 parts of SEBS (styrene-ethylene-butadiene-styrene), 9-12 parts of SBS (styrene-butadiene-styrene), 60-65 parts of rubber oil, 0.1-0.5 part of zinc stearate and 4-8 parts of silicone master batch. The thermoplastic elastomer plastic has the advantages of low price, high yield, favorable performance and favorable viscosity.

Description

technical field [0001] The present invention relates to a thermoplastic elastomer plastic formulation. 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, and can also be formed separately. Thermoplastic elastomers have both the processing performance of thermoplastics and the physical properties of vulcanized rubber. It is an advantageous combination of the advantages of plastic and rubber, so...
