ABS (Acrylonitrile Butadiene Styrene) material suitable for outdoor use and preparation method thereof

The invention relates to an ABS (Acrylonitrile Butadiene Styrene) material suitable for outdoor use and a preparation method thereof. The ABS material comprises the following components in parts by weight: 70-85 parts of ABS resin, 5-10 parts of a light screening agent, 5-10 parts of a surface modifier, 5-10 parts of a flexibilizer and 0.1-1 part of other auxiliaries. The preparation method comprises the following steps: dissolving the surface modifier and the light screening agent in distilled water at 40-60 DEG C, mixing and stirring, carrying out a pre-reaction, carrying out suction filtration and drying after the reaction is completed, uniformly stirring with the ABS resin, the flexibilizer and other assistants in a mixing barrel, and carrying out extrusion granulation by a twin-screw extruder to obtain the ultrahigh weather-resistant ABS material suitable for outdoor use. Compared with the prior art, the ABS material has the advantages that the problems of color change and the like of the ABS material in
