Description

Technical Field

[0001] The invention relates to the technical field of paint treatment, and in particular to a paint treatment process for the surface of a product shell. Background Art

[0002] At present, paint is a kind of chemical mixture coating that can firmly cover the surface of objects and other special purposes. It has the functions of anti-corrosion, waterproof, oil-proof, chemical-resistant, light-resistant, and temperature-resistant. Furniture is exposed to the atmosphere and eroded by oxygen, moisture, etc., which will cause wood decay and other damage. Applying paint on the surface of the product shell to form a protective film can prevent or delay the occurrence and development of these damage phenomena and extend the service life of various materials.

[0003] Special graphics or text labels are attached to the surface of the product shell, and users can complete operations according to these labels. Generally, users hope that when the product is not operated, the surface of the shell does not display the operation identifier, and when the product is operated, the surface of the shell can display the operation identifier for easy use. However, after the surface of the existing product shell is painted, the operation identifier on the surface of the product shell cannot achieve the display effect. Summary of the invention

[0004] Therefore, the present invention aims to solve the deficiencies in the prior art to at least a certain extent, thereby proposing a paint treatment process for the surface of a product shell.

[0005] To achieve the above object, a technical solution adopted by the present invention is:

[0006] The present invention provides a paint treatment process for the surface of a product shell, the process comprising the following steps:

[0007] S1. Grinding the surface of the shell, washing and shaking the shell;

[0008] S2, after the washed shell is naturally air-dried, spraying black paint on the inside of the shell and baking it to form a black paint surface on the inside of the shell;

[0009] S3, performing laser engraving on the black painted surface to form a required transparent pattern layer, spraying white paint on the transparent pattern layer, and then baking;

[0010] S4, spraying silver paint on the polished surface of the shell to form a silver paint layer and baking it.

[0011] Furthermore, in the step S1, the surface of the shell is polished by using 800-1000 mesh sandpaper.

[0012] Furthermore, in the step S1, the shell is placed in anhydrous ethanol for washing, and is further shaken and dispersed under 400-500W ultrasonic waves for 10-15 minutes.

[0013] Furthermore, in step S2, the baking temperature is 40-60° C. and the baking time is 20-40 min.

[0014] Furthermore, in step S3, the temperature of the laser engraving is 500-600°C.

[0015] Furthermore, in step S3, the baking temperature is 50-60° C. and the baking time is 30-40 min.

[0016] Furthermore, in step S4, the baking temperature is 60-70° C. and the baking time is 30-40 min.

[0017] Furthermore, the thickness of the silver paint layer is 10-15 μm.

[0018] The present invention provides a paint treatment process for the surface of a product shell, and the process includes the following steps: S1, grinding the surface of the shell, washing and shaking the shell; S2, after the washed shell is naturally air-dried, black paint is sprayed on the inside of the shell and baked to form a black paint surface inside the shell; S3, laser engraving is performed on the black paint surface to form a required transparent pattern layer, and white paint is sprayed on the transparent pattern layer, and then baked; S4, silver paint is sprayed on the surface of the shell after grinding to form a silver paint layer and baked. Through the process provided by the present invention, when the product is not lit, the surface of the shell can be made to have no display under the action of the silver paint layer, and the silver paint layer will cover the transparent pattern layer sprayed with white paint. When the light is turned on, the brightness of the light will penetrate the silver paint layer to display the content of the transparent pattern layer, so as to achieve the effect that the surface seems to have no pattern, and the pattern is displayed after the light is turned on.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the structures shown in these drawings without paying creative work.

[0020] Figure 1 The figure is a schematic flow chart of the paint treatment process for the surface of the product shell of the present invention. DETAILED DESCRIPTION

[0021] In order to make the purpose, features and advantages of the invention more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] The present application embodiment provides a paint treatment process for the surface of a product shell, the process comprising the following steps:

[0024] S1. The surface of the housing is polished smooth with 800-mesh sandpaper, and the housing is washed in anhydrous ethanol and continuously shaken under 400W ultrasonic wave for 10 minutes;

[0025] S2, after the washed shell is naturally air-dried, spray black paint on the inside of the shell and bake at 40° C. for 20 minutes to form a black paint surface on the inside of the shell;

[0026] S3, performing laser laser engraving at 500° C. on the black painted surface to form a required transparent pattern layer, spraying white paint on the transparent pattern layer, and then baking at 50° C. for 30 minutes;

[0027] S4, spraying silver paint on the polished surface of the shell to form a silver paint layer with a thickness of 10 μm and baking it at a temperature of 60° C. for 30 minutes.

[0028] In this embodiment, the above steps can make the overall effect of the product shell more beautiful than existing products. When the light inside the product in the embodiment of the present application is off, no icon will be displayed on the shell, and only when the light inside the product is on will a pattern be displayed on the shell.

[0029] Specifically, the outer surface includes an outer surface and an inner surface. A silver paint layer is sprayed on the outer surface, while black paint is first sprayed on the inner surface. After forming a black paint surface, a transparent pattern layer of the pattern content to be displayed is formed on the black paint surface by laser engraving, and then white paint is sprayed on the transparent pattern layer. In this way, the outer shell will not display anything when there is no light inside the product. The silver paint layer will cover the transparent pattern layer inside the outer shell sprayed with white paint. When the light inside the product is on, the brightness of the light will penetrate the silver paint layer to display the values ​​and icons displayed by the transparent pattern layer.

[0030] Among them, the transparent pattern layer is the numerical value and icon that needs to be displayed on the product shell, which is set according to the needs of the user. The content of the transparent pattern layer is not limited here and is set according to actual production needs.

[0031] Among them, white paint is sprayed on the transparent pattern layer so that the light can better and evenly display the content on the transparent pattern layer on the product shell.
