Abstract

The invention relates to the technical field of polymer materials, and discloses a high-strength flame-retardant ABS alloy material and a preparation method of the high-strength flame-retardant ABS alloy material. The ABS alloy material comprises the following raw materials in parts by weight: 20 to 80 parts of an ABS copolymer, 10 to 70 parts of polycarbonate, 3 to 10 parts of a compatibilizer, and 0.1 to 0.5 part of an antioxidant; the components are mixed, subjected to melt blending, extruded, air-dried and granulated to obtain the ABS alloy material. The alloy material disclosed by the invention has high strength and excellent fire resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-strength flame-retardant ABS alloy material and a preparation method thereof. Background technique [0002] ABS (acrylonitrile-butadiene-styrene) material has excellent chemical resistance, mechanical properties and excellent processing performance, so it is widely used in automobiles, home appliances, aviation, ships and other industries. With the continuous demand of products for materials, modified ABS is also appearing more and more in the market. ABS is one of the five major synthetic resin materials. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the advantages of easy processing, stable product size, and good surface gloss. It is easy to paint. It can also be used for secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bo...
