[0005] At present, only Kumho Hitachi has reported the literature on improving the photocorrosion phenomenon of home appliance materials, but there is no domestic report on the literature on the use of ABS as the base material to solve this problem and the use of photoblockers to solve this problem.
Patent No. CN201410770776.1, the name is a PC / ABS composition that can improve the photocorrosion phenomenon of air-conditioning panels and its preparation method. In this patent, PC / ABS is used as the base material, no photoblocker is used, and TIO2 is not grafted And surface coating treatment, no light shielding agent is used, which can only improve the light corrosion phenomenon of the air conditioning panel and cannot fundamentally solve the above problems

Embodiment 1
[0027]
[0028] The above light blocking agent is superfine talc powder treated with silane coupling agent, and the antioxidant is N, N'-bis[3-(3',5'-di-tert-butyl-4'-hydroxyphenyl)propane Hexamethylene diamide, lubricant is pentaerythritol stearate, light stabilizer is hindered amine HS-944, light shielding agent is carbon black, micro-nano semiconductor powder is a mixture of nano-ZnO and nano-ZnS.
[0029] The preparation method is as follows:
[0030] First, mix the micro-nano semiconductor powder and ABS resin in the mixer, and then add other materials except the light barrier agent and mix them evenly, then add them to the hopper of the twin-screw extruder, and at the same time mix the light barrier agent with It is added in the way of side feeding, melted, blended, extruded, cooled, air-dried, and pelletized to form an ABS alloy material that can solve the photocorrosion of plastic parts.

Abstract
The invention discloses an ABS alloy material capable of solving photocorrosion of a plastic part, and a preparation method of the ABS alloy material. The preparation method comprises the following steps: mixing micro-nano semiconductor power and ABS resin, mixing other materials except for a light blocking agent uniformly, adding the mixture into an extrusion machine, adding the light blocking agent in a side feeding mode, melting, extruding, cooling, air-drying and dicing to obtain the ABS alloy material capable of solving the photocorrosion of the plastic part. The preparation method provided by the invention is simple, the prepared ABS alloy material can realize ultrahigh definition and transparency, the route of the transparency of a plastic hidden display part is overturned, and the problem that the definition and the transparency of the plastic hidden display part are mutually contradicted is solved successfully; meanwhile, the photocorrosion phenomenon of the plastic part is solved fundamentally and the fact that any print does not exist on the long-term illumination surface is guaranteed. Due to the excellent photocorrosion resistance of the product, the photocorrosion phenomenon which perplexes the household appliance industry for more than ten years is solved and the hidden display design of the household appliance industry is not limited any more.
Description
technical field [0001] The invention relates to an ABS alloy material for solving the photocorrosion of plastic parts and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] At present, the development of the home appliance industry in various countries in the world is more and more based on human nature. Smart homes are slowly approaching all aspects of our lives. Human needs for home appliances are not satisfied with simple electrical functions, but hope that home appliances can become life Decoration, health, etc. are part of improving comfort. The smart life scene of "beautiful morning, healthy food, worry-free living, comfortable breathing, private kitchen, refreshment, and restful sleep" has become an inevitable trend in the development of home appliances. [0003] Hidden display is an important player in this home appliance revolution. Hidden display can maintain the integration of home appliance panels, ...
