Embodiment

[0036] A kind of preparation method of thermoplastic styrenic elastomer material, comprises the following steps:

[0037] (1) Mixture

[0038] Weigh the styrene-based elastomer and filler oil in parts by mass, put them into a high-speed mixer and stir until the styrene-based elastomer absorbs oil completely, then add the weighed polyolefin elastomer, polypropylene, and active inorganic filler , lubricant, antioxidant, and surface slip agent in a mixer, and stir together at high speed until they are evenly mixed;

[0039] (2) Extrusion granulation

[0040] The homogeneously mixed material in step (1) is melted and extruded by a single-screw or twin-screw extruder, and pelletized.

Abstract

The invention discloses a thermoplastic styrene elastomer material and a preparation method of the thermoplastic styrene elastomer material. The thermoplastic styrene elastomer material is prepared from a styrene elastomer, filling oil, a polyolefin elastomer, polypropylene, an active inorganic packing, a lubricating agent, an antioxidant and a surface slipping agent. The VOC content of the prepared thermoplastic styrene elastomer material is less than 300ppm (VDA278 test standard); the hardness is less than 90A (Shore); the melt mass flux rate is greater than 40g/10min (ISO1133-1:2001, 230 DEG C, 2.16Kg); the density of the prepared thermoplastic styrene elastomer material is greater than 1.4g/cm<3>; the elongation at break is greater than 200%; and the thermoplastic styrene elastomer material has certain sound insulation and vibration absorption properties.

Description

technical field [0001] The invention relates to a thermoplastic styrene elastomer material and a preparation method thereof. Background technique [0002] Thermoplastic styrene elastomer has the aging resistance, low temperature resistance and high elasticity of traditional rubber, and has the characteristics of simple and fast processing of plastics. It can be formed by extrusion, injection molding, blow molding and other plastic processing methods, and the material itself Non-toxic, environmentally friendly, with a comfortable feel, so its products can be widely used in various fields such as medical equipment, automotive interiors, sports equipment, toys and tools. [0003] Environmental protection, energy saving and comfort are the basic requirements for automotive interior materials. The current traditional automotive interior materials have high volatile organic compound (VOC) content, which seriously affects the health of passengers, and automotive materials are harmf...
