Problems solved by technology

However, the PC / ASA material only has the above advantages and is still insufficient. In the position where the human body is frequently in contact with the car, it is easy to be charged by friction, resulting in adverse phenomena such as electrostatic dust collection and spark discharge in a dry environment.

Embodiment 1-6 and comparative example 1

[0036] Mix the dried PC resin, antistatic agent, ASA, SAN and compatibilizer etc. according to the composition ratio in Table 1, and then use a twin-screw feeder to continuously and evenly add the twin-screw extruder (screw diameter 35mm, length-to-diameter ratio L / D=36) In the main cylinder, the temperature of the main cylinder is controlled in sections (from the feeding port to the nozzle outlet) to 170°C, 200°C, 220°C, 230°C, 230°C, 235°C, 225°C, and the twin-screw speed is 300 rpm / minute, the extruded strips are cooled in a water tank and then pelletized to obtain the product. Above-mentioned product is injection molded into standard spline with plastic injection molding machine after being dried at 85 ℃ for 4 hours in blast oven, and injection molding temperature is 230 ℃. The injection-molded strips were immediately placed in a glass desiccator at room temperature for at least 24 hours before performance testing. The test results are shown in Table 1.

Abstract

The invention discloses a high-heat resistance and low-gloss antistatic PC / ASA alloy material. The high-heat resistance and low-gloss antistatic PC / ASA alloy material comprises the following components in parts by weight: 60-80 parts of polycarbonate resin, 10-20 parts of an antistatic agent, 0-15 parts of an acrylonitrile-styrene copolymer, 4-20 parts of an acrylonitrile-styrene-acrylate graft copolymer, 0-5 parts of a grafted maleic anhydride compatibilizer, 0-1 part of an antioxidant and 0.1-2 parts of a matting agent. The technical scheme adopted in the invention has the benefits as follows: a polycarbonate / acrylonitrile-styrene-acrylate blending material adopting the technical scheme is excellent in heat resistance, has a permanent anti-static property and a low-gloss characteristic, and can be applied to car interiors.

Description

technical field [0001] The invention relates to the technical field of alloy materials, in particular to a PC / ASA alloy material with high heat resistance and low luster and antistatic properties and a preparation method thereof. Background technique [0002] PC / ASA material is one of the most commonly used plastics for automotive parts. It combines the excellent properties of PC and ASA, and combines the heat resistance, high strength, and high toughness of PC materials with the weather resistance, chemical resistance and processability of ASA materials. Features, often used in the manufacture of various automotive interior and exterior parts. However, the PC / ASA material only has the above advantages and is still insufficient. In the position of frequent contact with the human body in the car, it is easy to be charged by friction, resulting in adverse phenomena such as electrostatic dust collection and spark discharge in a dry environment. In order to solve this problem a...
