Abstract

The invention relates to a nylon plastic material for automobile electroplating as well as a preparation method thereof, and belongs to the technical field of automobile plastic. The invention aims toprovide the nylon plastic material for automobile electroplating as well as the preparation method thereof. By the method, the surface of a silicon dioxide microsphere is coated with a layer of alkalescent aluminum hydroxide with a porous structure through hydrothermal reaction, so that the lightweight effect is achieved, the specific surface area is enlarged and the adsorbing ability of the surface aluminum hydroxide on acid liquid is improved; and through compounding with nylon, the nylon material is easily etched in an acid solution and the etching effect is improved, so that the electroplating property of the nylon material is significantly improved. The method provided by the invention is simple and low in cost; the nylon material prepared by the method has small density, has excellent mechanical property and electroplating property, can significantly improve the electroplating property of an existing nylon material and can widely serve as an electroplating material for automobiles.

Description

technical field [0001] The invention relates to a nylon plastic material for automobile electroplating and a preparation method thereof, belonging to the technical field of automobile plastics. Background technique [0002] With the development of the automobile industry, automobile lightweight is a major development trend of today's automobile industry. "Replacing steel with plastic" is a very important direction to realize automobile lightweight. Some plastics such as nylon, polypropylene, and ABS are widely used in automobiles. More and more applications. [0003] Nylon has been widely used due to its excellent mechanical properties. It is currently the material with the largest consumption of the five major engineering plastics. Compared with PP, ABS and other materials, nylon has excellent mechanical properties, especially glass fiber reinforced nylon. It is used to replace metal materials in parts that require high mechanical properties of materials, and has been wide...
