Problems solved by technology

[0002] With the continuous advancement of technology, there are more and more choices of mobile phone body materials. At present, mobile phone bodies made of alloy materials have attracted the attention of major mobile phone brand manufacturers because of their good thermal conductivity and mechanical strength. However, Because the alloy material is easy to wear, and with the increase of use time, the color paint originally sprayed on the alloy surface is easy to wear off, which greatly affects the appearance of the mobile phone
[0003] At present, the surface ceramic treatment of alloys is often used to overcome defects such as easy wear of alloy materials. In the current process, alloys with surface ceramic effects are generally obtained by directly spraying ceramic paint on the surface of alloy substrates. This method can solve the problem that the alloy material is easy to wear after the surface ceramic treatment of the alloy, but when using the surface ceramic treatment alloy prepared by this method, user fingerprints are easy to stay on it, and this alloy is used to make mobile phones. It will greatly affect the appearance of the mobile phone

preparation example Construction

[0027] The present invention also provides a preparation method of the ceramicized anti-fingerprint coating, comprising:

[0028] Form a ceramic layer on the surface of the alloy;

[0029] An anti-fingerprint layer is formed on the surface of the ceramic layer.

[0030] It should be noted that the method for forming the ceramic layer on the surface of the alloy is as follows: polishing the alloy so that the surface roughness of the alloy is 0.5 μm-1.5 μm; forming a pretreatment layer on the surface of the alloy after polishing; A ceramic layer is formed on the surface;

[0031] Specifically, the method for forming a pretreatment layer on the polished alloy surface is as follows:

[0032] Spray the metal surface treatment agent on the polished alloy surface, and bake it to obtain a pretreatment layer; wherein, the baking temperature is 60°C-70°C, and the baking time is 3min-8min; after the alloy is treated in this way, it can be Enhance the adhesion of the coating in the sub...

Embodiment 1

[0041] This embodiment provides a method for preparing a vitrified anti-fingerprint coating, including:

[0042] Polish the alloy to make the alloy surface flatness 0.5 μm, then spray the metal surface treatment agent on the polished alloy surface, and bake at 60°C for 3 minutes, and form a 3 μm thick alloy surface on the polished alloy surface. Pretreatment layer; then spray paint on the surface of the pretreatment, and bake at a temperature of 70 ° C for 3 minutes to obtain a ceramic layer with a thickness of 15 μm; after the ceramic layer is formed, spray ultraviolet light curing paint on the surface of the ceramic layer, And bake at a temperature of 50°C for 3 minutes, and then use an energy of 550mj / cm 2 The ultraviolet light cured paint after the ultraviolet ray irradiation and baking, obtains the adhesion layer with a thickness of 22 μm; then vacuum electroplating silicon titanium material layer on the surface of the adhesion layer, obtains the brightness enhancement la...

Embodiment 2

[0044] This embodiment provides a method for preparing a vitrified anti-fingerprint coating, including:

[0045] Polish the alloy to make the alloy surface evenness 1.0 μm, then spray the metal surface treatment agent on the polished alloy surface, and bake it at 65°C for 8 minutes to form a 2 μm thickness on the polished alloy surface. Pretreatment layer; then spray paint on the pretreatment surface, and bake at 80 ° C for 8 minutes to obtain a ceramic layer with a thickness of 12 μm; after the ceramic layer is formed, spray ultraviolet light curing paint on the surface of the ceramic layer, And bake at a temperature of 60°C for 8 minutes, and then use an energy of 650mj / cm 2The ultraviolet photocuring paint after the ultraviolet ray irradiation and baking obtains an adhesive layer with a thickness of 18 μm; then, a silicon titanium material layer is vacuum-plated on the surface of the adhesive layer to obtain a brightness-enhancing layer with a thickness of 0.4 μm; after the...
