Abstract

The invention discloses a curved surface coating method based on nanometer spraying and plating. The curved surface coating method is characterized by comprising the following steps of firstly, surface pretreatment; secondly, nanometer spraying and plating, wherein a nanometer spraying and plating solution including no silver nitrate is prepared, a spraying gun is utilized for spraying the nanometer spraying and plating solution to the surface of a workpiece, and conventional cleaning and drying are achieved; and thirdly, curved surface coating, wherein (a) manufacturing of a water coating transfer printing film, (b) film paper immersion in water, (c) transfer printing, (d) water washing, (e) drying, (f) gloss oil spraying and (g) drying are carried out. According to the curved surface coating method, the nanometer spraying and plating solution including no silver nitrate is adopted as a curved surface coating bottom layer, the adhesive force of a curved surface coating pattern layer can be greatly improved, and the method can be widely applied to the industry such as the sanitary industry.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a method for coating curved surfaces based on nano-plating. Background technique [0002] Nano-plating is a process in which silver-ammonia solution is sprayed on the surface of the workpiece to form a high-gloss mirror surface by using a silver mirror reaction. Products sprayed with this technology have excellent adhesion, impact resistance, corrosion resistance, weather resistance, wear resistance and scratch resistance, and have good anti-rust performance. They are generally used in the sanitary industry, large-scale domestic and foreign The surface treatment of precision products such as automobile manufacturers and large electrical appliance manufacturers can also be used as surface decoration and protection spraying in other industries. The process is simple, green and environmentally friendly, and it is a high-tech surface treatment technology. [0003] Curved s...
