Embodiment 1

[0019] In Example 1, the matting agent required by the present invention was not added.

[0020] The preparation method of the alloy material of this embodiment is specifically as follows:

[0021] 1) Weigh PC500g, ABS450g, 50g of compatibilizer, 2g of antioxidant, and 4g of lubricant for use. Among them, ABS is fully dried in advance at 80-85℃ and PC at 90-100℃ in a dryer.

[0022] 2) Add PC, ABS, and compatibilizer to a high-speed mixer and mix for 5 minutes, then add antioxidants and lubricants in sequence and mix well;

[0023] 3) The mixture obtained in step 2) is added to a co-rotating twin-screw extruder for extruding and granulating at a rotation speed of 300-400r / min and a temperature of 230-260°C. After cooling in a water tank, the mixture is cut into PC / ABS alloy materials.

[0024] According to the preparation method of Example 1, the preparation and index analysis of the alloy materials of Examples 2-5 were performed according to the ratio of Table 1 below.

Abstract

The invention provides an extinctive PC / ABS (Poly Carbonate / Acrylonitrile Butadiene Styrene) plastic alloy which is prepared from the following components in percentage by weight: 30-50% of PC, 40-65% of ABS, 1-10% of compatilizer, 1-5% of flatting agent, 0.2-1% of lubricant and 0.2-1% of antioxidant. The extinctive PC / ABS plastic alloy provided by the invention has the advantages of low surface glossiness, good toughness and flowability, low cost and the like. The manufacturing method is simple in processing step and low in comprehensive cost and is especially suitable for the fields of electronics, home appliances, automotive trims and the like.

Description

Technical field [0001] The invention belongs to the technical field of plastic alloys, and specifically relates to a matting PC / ABS plastic alloy and a manufacturing method. Background technique [0002] With the advancement of science and technology and industrial development, ABS resin has become more and more widely used in automobiles, home appliances, electronic appliances and other fields, resulting in a huge increase in demand. However, ABS resin itself has many performance deficiencies and defects, such as strength, heat resistance, weather resistance, and poor surface hardness, which hinder and limit the further application of ABS resin. Therefore, the research on the modification of ABS has attracted much attention. At present, most of the improved workability products of ABS are made by blending polycarbonate (PC) with ABS to prepare PC / ABS alloys. PC / ABS alloys currently have general-purpose, high-flow, flame-retardant grades. The surface gloss of ordinary PC / ABS is...
