Matte ABS resin composition and preparation method thereof

Abstract

The invention discloses a matte ABS resin composition and a preparation method thereof. The composition comprises, in parts by weight, 100 parts of ABS resin, 0.5-10 parts of a polymer micropowder, 0.5-5 parts of a compatibilizer, 0.05-1 part of an anti-oxidant, and 0.1-2 parts of a lubricant. The polymer micropowder is a semicrystalline polyamide micropowder, the molecular main chain contains a repeated amide group -[NHCO]-, the melting point is 245-390 DEG C, the glass-transition temperature is 55-185 DEG C, and the particle size is 1-50 mu m. The matte ABS resin composition is obtained by pre-mixing the above raw materials in a high-speed mixer for 3-10 min and then performing extrusion granulation on the premix through a double-screw extruder. Compared with the prior art, the ABS resin composition with excellent matte effect is directly prepared through a one-step process, the preparation method is simple in technology, the prepared ABS resin composition is super low in luster, and the problems that luster distribution is not uniform, physical and mechanical performances are deteriorated and technology is complex are solved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a matte ABS resin composition and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer (ABS) is an engineering plastic with excellent comprehensive properties such as high gloss, chemical corrosion resistance, high heat resistance, easy processing, and excellent dimensional stability. It has a wide range of applications in automobiles, household appliances, offices and other fields. When ABS resin is used in many electronic appliances and automotive interior components, such as computer casings, keyboards, mice, instrument panels, sun visors, and navigator frames in automotive interiors, it is often necessary to achieve a surface with a matting effect. Especially in the field of automotive interiors, in order to avoid the visual disturbance caused by the reflection of sunlight on the driver and reduce the driver's visual fatigue,...
