preparation example Construction

[0029] The preparation method of the ABS composite material with matte effect comprises the following steps:

[0030] The ABS resin, the matte powder, and the antioxidant are weighed according to the formula, and premixed in a high-speed mixer for 5-10 minutes to obtain a premix;

[0031] The premixed material is added to a twin-screw extruder for extrusion and granulation to obtain an ABS composite material with a matte effect.

[0032] Further, the temperature setting of the twin-screw extruder is: 160-180°C in the first zone, 180-190°C in the second zone, 180-190°C in the third zone, 180-190°C in the fourth zone, 180-190°C in the fifth zone, The sixth zone is 180-190°C, the seventh zone is 180-190°C, the eighth zone is 180-190°C, the ninth zone is 180-190°C, the tenth zone is 180-190°C, and the machine head is 190-200°C.

[0033] Further, the rotational speed of the screw is 300-400r / min, and the screw aspect ratio of the twin-screw extruder is 40-52.

[0034] Further, in...

Embodiment 1-6 and comparative example 1-2

[0036] The formulations (unit: %) of the ABS composite materials in Examples 1-6 and Comparative Examples 1-2 are shown in the table below. Prepare materials according to the components and contents of each embodiment and comparative example in Table 1; fully stir and premix the prepared materials in a high-speed mixer, and in a preferred embodiment, premix for 8 minutes; finally add the premix ABS composite material can be obtained by extruding and granulating with twin-screw extruder. The preparation process of the ABS composite material of the invention is simple, and the existing equipment can be used for mass production.

[0037] In the above example, the temperature setting of the twin-screw extruder is: 170°C in the first zone, 185°C in the second zone, 185°C in the third zone, 180-190°C in the fourth zone, 185°C in the fifth zone, 185°C in the sixth zone, The seventh zone is 185°C, the eighth zone is 185°C, the ninth zone is 185°C, the tenth zone is 190°C, and the mac...

Abstract

The invention discloses an ABS (acrylonitrile butadiene styrene) composite material with a matte effect and a preparation method thereof, the ABS composite material with the matte effect comprises the following components in percentage by mass: 95.5-97.8% of ABS resin, 2-4% of matte powder and 0.2-0.5% of antioxidant, the matte powder is a silicon dioxide powder material, and the particle size of the matte powder is 1.5 + / -0.1 mu m. The preparation method comprises the following steps: premixing the raw materials in a high-speed mixer for 5-10 minutes, and then extruding and granulating the premix through a double-screw extruder to obtain the ABS composite material. When the ABS composite material with the matte effect is prepared, the temperature of each section of the double-screw extruder is 20-30 DEG C lower than that of a normal process, and the production process is simple and convenient. Meanwhile, the temperature is 20 DEG C lower than the normal injection molding temperature during sample injection molding, so that the ABS composite material with the matte effect is simple in preparation process and low in energy consumption.

Description

technical field [0001] The invention relates to the field of ABS resin modification, in particular to an ABS composite material with a matte effect and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer (ABS) is a kind of engineering plastic with excellent comprehensive performance, which is widely used in the fields of electronics, automobiles, household appliances, office supplies, etc. Decoration is favored by users due to its long service life and various shapes. In order to avoid accidents caused by interference with the driver's vision, the parts made of ABS material suitable for automobiles need to have a certain matte effect. [0003] In order to make the ABS material parts achieve a matte surface effect, the following methods are generally used: [0004] 1. The surface of the mold is roughened and the ABS material is made by the body method. Due to the different synthesis methods of the ABS material prepared by t...
