Matte thermoplastic elastomer composition and preparation method thereof

InactiveCN102875948AGood physical propertiesGood processing fluidityPolypropyleneChemistry
The invention discloses a matte thermoplastic elastomer which comprises, by weight, 20%-45% of styrene block copolymers, 30%-60% of filling oil, 5%-20% of polypropylene, 5%-12% of olefin thermoplastic elastomers, 0.5%-4% of organic matting agents, 0.1%-2% of stabilizers, 0.01%-0.05% of cross-linking agents and 0%-30% of inorganic filler. A preparation method includes: proportionally weighing raw materials, mixing the styrene block copolymers, the inorganic filler, the polypropylene, the olefin thermoplastic elastomers, the organic matting agents, antioxidants, the cross-linking agents and other auxiliaries in a high-speed mixer, and placing the mixture into a double-screw extruder for melt extrusion and extruding out prior to cooling, drying and grain cutting so that a finished product is obtained. By the method, the cross-linking agents of a proper amount and the organic matting agents of a proper amount are added into the thermoplastic elastomer, so that the prepared thermoplastic elastomer has a matting characteristic, and a visual effect is extremely soft. Intrinsic physical performances of the thermoplastic elastomer are basically kept, and the matte thermoplastic elastomer is extraordinarily excellent in processability, suitably applied to interior decoration materials of household appliances, automobiles and the like and particularly suitable for large-area injection molding products.
