preparation example Construction

[0043] One embodiment of the present invention provides a method for preparing 3D anti-glare glass (i.e. 3D AG glass), comprising the following steps:

[0044] S100: Provide 2D glass substrate, 2D glass substrate contains AG layer.

[0045] It can be understood that the 2D glass substrate containing the AG layer in step S100 can be prepared by methods acceptable in the art, and there is no special limitation here, and it should be understood that all are within the protection scope of the present invention.

[0046] Further, the following method is used to obtain a 2D glass substrate containing an AG layer:

[0047] S110: coating protective oil on the glass surface.

[0048] By printing protective oil on the surface of the glass to prevent scratches and the like in the subsequent process, the type of protective oil can be the type of protective oil commonly used in this field, as long as it does not conflict with the purpose of the present invention, it can be determined acco...

Embodiment 1

[0133] The preparation method of 3D AG glass is as follows:

[0134] (1) Print protective oil on the surface of a large 2D glass substrate (1.8m*1.5m) to prevent scratches;

[0135] (2) Cut the large piece of glass into small pieces of glass, the size of which is 1mm larger than the length and width of the CNC carving shape;

[0136] (3) Frosting: the concentration is 7.5Kg water / 25kg frosting powder, the temperature is 30°C, the time is 8min; deoiling: the reagent is sodium hydroxide, the concentration is 15%, the temperature is 85°C, and the time is 6min; Throwing: the temperature is 20°C, and the time is 5 minutes;

[0137] (4) CNC engraving the desired shape;

[0138] (5) Polish and clean the burrs generated on the CNC edge;

[0139] (6) Preheating, hot-bending and cooling the polished 2D glass substrate in sequence, wherein the preheating step includes the first, second, third, fourth and fifth preheating stages, respectively Preheating 1-preheating 5, the mold temper...

Embodiment 2

[0152] Substantially the same as Example 1, the difference lies in the acid strength formula (mass percentage composition) of the acid strengthening treatment of step (8): sodium fluoride 10%, citric acid 10%, fatty alcohol polyoxyethylene ether sodium sulfate 0.5%, water balance.

Abstract

The invention relates to 3D anti-dazzle glass, a preparation method of the 3D anti-dazzle glass and a mobile phone cover plate. The preparation method of the 3D anti-dazzle glass comprises the following steps: providing a 2D glass substrate containing an AG layer; performing hot bending forming treatment on the 2D glass substrate containing the AG layer, and preparing a 3D glass crude product; performing strengthening treatment on the 3D glass crude product, and preparing the 3D AG glass, wherein the step of hot bending forming treatment comprises at least one hot bending forming stage, and in each hot bending forming stage, the temperature of a mold close to an AG layer does not exceed 660 DEG C; and in at least one hot bending forming stage, the temperature of the mold close to the AG layer is higher than 630 DEG C. According to the preparation method, AG particle damage can be effectively avoided, so the 3D AG glass prepared by the method has a higher anti-dazzle effect and is particularly suitable for preparing a mobile phone cover plate.

Description

technical field [0001] The invention relates to the technical field of glass preparation, in particular to 3D anti-glare glass, a preparation method thereof and a mobile phone cover plate. Background technique [0002] Etched glass is the use of etchant to corrode the engraved glass. Etched glass with text or patterns and patterns is used as decorations. It is beautiful and generous. It is a glass product commonly used in architectural decoration. With the development of technology, AG glass (anti-glare glass) is more and more widely used. After special chemical treatment of the glass surface, the microscopic particle structure of the glass surface changes into uneven particles (ie AG particles), thus The specular reflection of the glass is artificially converted into diffuse reflection, and at the same time, the rough particles on the glass surface are turned into smooth particles through the chemical process of enhancing the light transmittance, which improves the light tr...
