Embodiment 1

[0039] This embodiment relates to a low-gloss heat-resistant ABS resin composition and a preparation method thereof, which are specifically described as follows.

[0040] 1. Preparation of matte masterbatch D (see Table 1 for components and weight content):

[0041] Resin A containing maleic anhydride (MAH) functional group, resin B containing glycidyl methacrylate (GMA) functional group, polyolefin-alkyl acrylate copolymer C, fumed silica, zinc borate hydrate and Antioxidant B9000.3phr and lubricant EBS 1.0phr are fully stirred and mixed in a high-speed mixer, and then sent into a twin-screw extruder through a metering device. Under the conveying, shearing and mixing of the screws, the materials are melted and compounded. Then through the steps of extruding, drawing, cooling and pelletizing, matt masterbatches D1-D8 with uniform particle size are obtained.

[0042] The aspect ratio of the screw of the twin-screw extruder is 40, the temperature of the front section is 200-230...

Embodiment 2～6

[0056] Embodiments 2-6 relate to the preparation of low-gloss heat-resistant ABS resin compositions, and the preparation method is the same as that of Embodiment 1. The components and parts by weight of the low-gloss heat-resistant ABS resin compositions corresponding to Examples 2-6 are shown in Table 3.

Abstract

The invention relates to a low-gloss heat-resistant ABS (Acrylonitrile Butadiene Styrene) resin composition and a preparation method thereof. The low-gloss heat-resistant ABS resin composition comprises the following components in parts by weight: 100 parts of acrylonitrile butadiene styrene resin, 5 to 30 parts of a heat-resistant agent, 1 to 5 parts of matte master batches, 0.2 to 1.0 part of a light stabilizer and 0.5 to 2.0 parts of other auxiliaries. The preparation method comprises the following steps: stirring and fully mixing the raw materials in a high-speed mixing machine; feeding the mixture into a twin-screw extruder through a metering device; melting and compounding the materials under the conveying, shearing and blending actions of screws; extruding, stripping, cooling and granulating to obtain the low-gloss heat-resistant ABS resin composition. The resin composition provided by the invention is high in mechanical performance, ultralow in gloss, and particularly suitable for the field of automobile interiors.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a low-gloss heat-resistant ABS resin composition and a preparation method thereof, in particular to a low-gloss heat-resistant ABS resin composition applicable to automotive interior parts 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. In order to avoid the safety hazard caused by strong light and visual pollution caused by the reflection of sunlight on the driver, the car interior generally adopts matting treatment to reduce the glossiness of the interior parts as much as possible. Generally speaking, there are usua...
