Abstract

The invention discloses a surface treatment technology with ceramic and fingerprint simulating effects and application. The surface treatment technology comprises the following steps that firstly, dirt removal cleaning is conducted on the surfaces of formed base materials, and drying treatment is conducted; secondly, UV primer is sprayed to a cleaned spraying piece, and drying treatment is conducted; thirdly, finishing coat is sprayed to the surface of the spraying piece, and drying treatment is conducted; fourthly, the spraying piece to which the finishing coat is sprayed is placed in an optical plating furnace, and optical color film plating is conducted on the spraying piece through optical vacuum plating; and fifthly, the spraying piece to which an optical color film is sprayed is placed in the other optical plating furnace, and plating of an AF clad layer material is conducted on the spraying piece through optical vacuum plating. Through spraying of the UV primer and the finishingcoat, sequential plating of the optical color film and the AF clad layer material is conducted, the product surface achieves the ceramic simulating effect, and flexibility and gloss texture are good;and meanwhile, good fingerprint preventing, pollution preventing and waterproof effects can be achieved, and surface abrasion resistance and hardness are improved.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular relates to a surface treatment process and application with imitation ceramics and anti-fingerprint effects. Background technique [0002] Traditional industrial ceramics are ground into powder by ring grinding and added to the base material, then semi-products are formed by potting glue or nano-injection molding, and finally finished products are formed by degreasing sintering, polishing and CNC processing. Among them, powder grinding, glue potting, Polishing and other processes are highly polluting processes, and traditional ceramics are fragile and not suitable for consumer products. [0003] In order to solve this problem, the inventor designed a spraying method, such as the Chinese invention patent, the application number is 201811210915.X, and the name is the high-imitation ceramic appearance effect spraying method. The invention patent specifically discloses a h...
