Technical Field

The invention relates to the technical field of glass processing, in particular to glass with a combined matte effect and a preparation method thereof.

Background

Along with the development of science and technology, people's standard of living's improvement, people are more and more high to the requirement of cell-phone outward appearance, in order to promote the back lid decorative effect of setting at the cell-phone back, generally can adopt to decorate the lining support in whole AG matte, flash of light sand or diaphragm and embody the effect.

However, the existing decoration is a whole AG fog surface or a smooth surface and glittering sand, and then films with different colors are set off to have various effects. The mode is still single, and the diversified effect can not be reflected. Therefore, a new mobile phone rear cover product is needed to increase the diversification effect of the rear cover glass.

Disclosure of Invention

Based on the technical problems in the background art, the invention provides glass with combined matte effect and a preparation method thereof.

The invention provides a preparation method of glass with a combined matte effect, which comprises the following steps:

s1, forming a protective film on one side surface of the glass, wherein the area without the protective film on the side surface of the glass forms a preset pattern;

s2, atomizing the area without the protective film on the side surface of the glass, and etching and thinning the atomized area;

and S3, removing the protective film on the surface of one side of the glass, and performing AG etching on the surface of the side of the glass to obtain the glass with the combined matte effect.

Preferably, the protective film is obtained by printing or yellow light processing on one side surface of the glass.

Preferably, the printing is by a screen printing process.

Preferably, the yellow light process specifically comprises: and forming a photosensitive protective film on one side surface of the glass, exposing the photosensitive protective film, and developing to obtain the protective film.

Preferably, before forming the protective film on one side surface of the glass, ultrasonic cleaning is further performed on the side surface of the glass.

Preferably, the atomization is achieved by a sand blasting process.

Preferably, the thickness of the etching reduction is 5-20 μm.

Preferably, the AG etching is obtained by reacting one surface of the glass with an AG chemical solution.

The invention also provides glass with a combined matte effect, which is prepared by the preparation method.

The invention provides glass with a combined matte effect and a preparation method thereof, wherein the surface of the glass is firstly subjected to printing or yellow light process treatment, so that a preset pattern is formed on an area without a protective film on the surface of the glass; then, sand blasting is carried out on the surface of the glass, so as to form atomization in the area without the protective film on the surface of the glass, and then the area after atomization is etched, so that the thickness of the area is reduced by 5-20 mu m; finally, the protective film is removed, and AG etching is performed. Here, since the region of the glass surface from which the protective film is removed is not subjected to the blast treatment before the AG etching (has a smooth surface), and the region not covered with the protective film before is subjected to the blast treatment (has a rugged result), the matte effect of the corresponding regions after the same AG etching treatment is different, and the combined matte effect is exhibited. And because the area which is not covered by the protective film on the glass surface is thinned to a certain thickness, the finally presented matte effect and the area which is not thinned have more distinct contrast effect, and finally, the effect of a plurality of clearly defined matte contrast combinations is formed on the glass surface.

Therefore, the novel glass combined matte (well combined) product method provided by the invention can form different effects according to combined patterns when being used on the rear cover of the mobile phone glass combined matte; therefore, the mobile phone rear cover is not limited by a single process and can not show diversified effects. Compared with the existing effect that the decoration is a whole AG matte surface or a glossy surface and glittering sand, the preparation process is more novel, and the yield of the combined matte surface can be effectively improved.
