Low-gloss abs resin composition and preparation method thereof

Abstract

The invention discloses a low-gloss ABS resin composition and a preparation method thereof. The composition is prepared from 100 parts of ABS resin, 0.5-10 parts of polymer micro-powder, 0.5-5 parts of compatilizer, 0.05-1 part of an antioxidant and 0.1-2 parts of a lubricant. Semicrystalline polyethylene glycol terephthalate micro-powder is adopted as the polymer micro-powder, the intrinsic viscosity of the micro-powder is 0.9-1.4 dL / g, the melting point of the micro-powder is 245 DEG C-270 DEG C, the glass-transition temperature of the micro-powder is 70 DEG C-85 DEG C, and the particle size of the micro-powder is 1-50 micrometers. All the components are premixed in a high-speed mixer for 3-10 minutes, extrusion pelletizing is performed on premix through a double-screw extruder, and then the low-gloss ABS resin composition is obtained. Compared with the prior art, the ABS resin composition with the excellent matte finish effect is directly prepared through a one-step method, the preparation method is simple in technological process, the glossiness is ultra-low, and the problems of uneven glossiness distribution, physical and mechanical performance deterioration and a complex technology are solved.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a low gloss 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 fati...
