Problems solved by technology

[0003] In the process of automobile instrument panel panel processing, it is generally necessary to use laser engraving technology for pattern engraving, but when the existing laser engraving process is processed, the edge of the pattern will be coked due to laser engraving, so that the pattern is blurred and unclear. In practical applications bring inconvenience

Abstract

According to the laser etching spraying process for an instrument panel. During panel machining, firstly, a panel base plate is taken and subjected to ultrasonic cleaning through a degreasing agent and deionized water in sequence, so that oil stains and impurities on the surface of the panel base plate are removed, and the coating effect of a subsequent coating is prevented from being influenced; and then the surface of the panel base plate is coated with UV photocuring primer and imitation metal anodic oxidation paint to form a primer layer and a finish paint layer, the primer and the finish paint are selected from existing coatings purchased in the market, and the primer and the finish paint can be selected according to actual requirements in actual operation. According to the laser etching spraying process for the instrument panel, the process design is reasonable, the operation is simple, after the surface of a prepared panel substrate is subjected to laser etching processing, the pattern color is clear, the pattern shape is accurate, the surface of the panel substrate is coated with antibacterial gloss oil, the antibacterial performance is excellent, and the practicability is relatively high.

Description

technical field [0001] The invention relates to the technical field of radium engraving technology, in particular to a radium engraving spraying process for instrument panel panels. Background technique [0002] Laser engraving generally refers to laser engraving. Laser engraving is based on numerical control technology, and laser is the processing medium. The physical denaturation of the instant melting and gasification of the processing material under the irradiation of laser engraving can make laser engraving achieve the purpose of processing. Laser engraving is the use of laser technology to engrave text on objects. The characters engraved by this technology have no notches, the surface of the object is still smooth, and the writing will not wear out. [0003] In the process of automobile dashboard panel processing, it is generally necessary to use laser engraving technology for pattern engraving, but when the existing laser engraving process is processed, the edge of ...
