[0050] The parts by weight of each raw material are shown in Table 1.

[0051]Add PC resin, ABS resin, and various additives to a high-speed mixer and stir at high speed for 2 minutes, then add them to the main feeder of the extruder, and then add them to the twin-screw extruder for basic granulation. The temperature distribution of the extruder is as follows: from the feed section to the head: 240°C, 260°C, 260°C, 260°C, 255°C, 250°C, 250°C, 250°C, 250°C, die head: 260°C , After the material is extruded, it is water-cooled, pelletized, and then packaged. The pellets were dried in a blast oven at 90°C for 4 hours, and then test specimens were prepared by an injection molding machine.

Abstract

The invention provides a low-VOC high-performance PC / ABS alloy material and its preparation and an application thereof. Raw material formula of the alloy material contains: by weight, 30-80 parts of polycarbonate, 5-50 parts of a styrene-butadiene-acrylonitrile copolymer, 5-30 parts of a styrene-acrylonitrile copolymer, 1-10 parts of a compatilizer, 0.1-1.0 part of an odour absorbent and 0.1-1 part of a processing agent. The alloy material provided by the invention has low odour grade, low content of an organic volatile matter and excellent mechanical property, and can be used in preparation of automotive upholstery.

Description

technical field [0001] The invention relates to a composite material, in particular to a low-VOC high-performance PC / ABS alloy material and its preparation, which is mainly used for preparing automotive interior parts. Background technique [0002] With the large-scale entry of cars into homes in our country, the problem of air safety in cars has become increasingly prominent. Generally speaking, the smell of new cars is mainly due to the volatile organic compounds emitted from the car, collectively referred to as VOC (Volatile pounds), the most common of which is There are: benzene, toluene, ethylbenzene, acetaldehyde, formaldehyde, acrolein, ethanol, styrene, tetradecane, ethyl acetate, etc., and these harmful substances such as benzene, toluene, formaldehyde, and xylene are the most harmful to the human body. Especially in the long-term closed car environment, due to the lack of air circulation, the VOC concentration is high, and the people in the car are prone to poisoni...
