Abstract

The invention discloses a preparation method of a scale-like high-weather-resistance ABS material. belonging to the technical field of ABS materials. According to the preparation method, the weather resistance of the ABS material can be improved by mixing titanium dioxide in raw materials; meanwhile, extinction bags are introduced in a foaming process, and the extinction bags are forced to adhere to a wall to achieve uniform distribution under magnetic attraction effect; the extinction bags are pre-embedded in the outer surface of the ABS material after being formed, and when irradiated by strong light, the extinction bags can convert light energy into heat energy so as to heat the extinction bags, then the deformation action of the extinction bags is triggered through the phenomenon of thermal expansion, the extinction bags expand on the surface to form similar extinction scales, and the multiple extinction scales are combined to cover the surface of the ABS material, so the ultraviolet protection performance of the ABS material is improved, the weather resistance of the ABS material is obviously improved, and the ABS material is not easy to degrade; and the shapes of the extinction bags are recovered for self-protection after external illumination is weakened, and interference on the use of the ABS material is reduced.

Description

technical field [0001] The invention relates to the technical field of ABS materials, in particular to a method for preparing a scale-like ABS material with high weather resistance. Background technique [0002] (ABS is the acronym for Acrylonitrile Butadiene Styrene, which refers to acrylonitrile-butadiene-styrene copolymer) is a thermoplastic polymer structure material with high strength, good toughness and easy processing, also known as ABS resin . [0003] Acrylonitrile-butadiene-styrene copolymer (referred to as ABS resin) is one of the five major synthetic resins. It has excellent impact resistance, heat resistance and low temperature resistance; it has the advantages of easy processing, stable product size and good surface gloss. At the same time, it is easy to paint and color, and it can carry out secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bonding, and is widely used in industries such as machinery, automobiles, el...
