Problems solved by technology

This type of technology has the following disadvantages: the precision of spraying or silk screen printing is not enough, and the edge is jagged obviously, which cannot meet the needs of high-end products; It is very easy to be corroded and severely jagged, resulting in low production yield
This method is not easy to operate, the edge of the protective film is easy to warp, and it is easy to enter the liquid to corrode the glass during chemical etching, which fails to achieve the purpose of protection, and the production yield is not high, so it is not suitable for large-scale production

Embodiment 1

[0030] The invention relates to a local anti-glare treatment process for glass surface. The method comprises the steps of:

[0031] 1. Cut the glass substrate according to the specified size (the size is 400mm × 500mm), and then clean it. The glass has a first surface and a second surface opposite to each other. The glass is float glass, the air side is the first surface, and the tin side is the second surface; if it is overflow glass, there is no need to distinguish;

[0032] 2. Spin-coat an acid-resistant photoresist (the specific photoresist is DIR620-09) on the first surface, then bake and cure at a temperature of 100°C for 10 minutes, then expose and develop, and retain Photoresist for local non-glare areas and target positions;

[0033] 3. Attach an acid-resistant film on the second surface;

[0034] 4. Frosting treatment is carried out on the first surface. Frosting powder is prepared from the following materials and matured for more than 24 hours: 11.65Kg ammonium b...

Embodiment 2

[0042] 1. Cut the glass substrate (size is 400 × 500) according to the specified size, and then clean it. The glass has a first surface and a second surface opposite to each other;

[0043] 2. Spin-coat an acid-resistant photoresist on the first surface (the specific photoresist is GIR2708), and then bake and cure at a temperature of 105°C for 10 minutes, then expose and develop, and keep the parts that are not exposed Photoresist for anti-glare areas and target locations;

[0044] 3. Attach an acid-resistant film on the second surface;

[0045] 4. Frosting treatment is carried out on the first surface. Frosting powder is prepared from the following materials and matured for more than 24 hours: 14.5Kg ammonium bifluoride, 3.85Kg citric acid, 1.5Kg barium sulfate, 2.4Kg starch, 1.2Kg bentonite, trioxide 5Kg of iron, 3Kg of calcium fluoride, 4Kg of potassium nitrate, 1.2Kg of hydrofluoric acid and 8Kg of water; wash after frosting treatment for 90S;

[0046] 5. Removing the ph...

Embodiment 3

[0052] 1. Cut the glass substrate (size is 400 × 500) according to the specified size, and then clean it. The glass has a first surface and a second surface opposite to each other;

[0053]2. Spin-coat an acid-resistant photoresist on the first surface (the specific photoresist is GIR2708), and then bake and cure at a temperature of 100°C for 10 minutes, then perform exposure and development, and keep the parts that are not exposed Photoresist for anti-glare areas and target locations;

[0054] 3. Attach an acid-resistant film on the second surface;

[0055] 4. Frosting treatment is carried out on the first surface. Frosting powder is prepared from the following materials and matured for more than 24 hours: 12Kg ammonium bifluoride, 2.5Kg citric acid, 1Kg barium sulfate, 1.8Kg starch, 1.0Kg bentonite, 4.5 kg iron oxide Kg, calcium fluoride 2.5Kg, potassium nitrate 4.0Kg, hydrofluoric acid 1.0Kg and water 8Kg; wash after frosting treatment for 60S;

Abstract

The invention provides a local AG glass processing method which comprises the following specific steps: S1, cutting a glass substrate which is provided with a first surface and a second surface which are oppositely arranged; s2, coating the first surface with an acid-resistant photoresist, baking and curing, exposing and developing, and reserving the photoresist at the local non-anti-dazzle area and the target position; and pasting an anti-acid film on the second surface; s3, frosting treatment is carried out on the first surface, cleaning is carried out after frosting treatment, and the photoresist on the first surface is removed; and s4, polishing the first surface, and then cleaning; and the anti-acid film on the second surface is removed, peelable glue blue films are subjected to silk-screen printing on the first surface and the second surface, and local AG treatment is completed. According to the method provided by the invention, the position precision of the local AG can be greatly improved, meanwhile, the sawtooth effect at the junction of the AG area and the non-AG area is obviously improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of glass surface treatment; more specifically, it relates to a partial AG glass processing method. Background technique [0002] AG (Anti-glare) glass is also called anti-glare glass. It is a kind of glass with special treatment on the glass surface. Its feature is to change the specular reflection of the original glass surface into diffuse reflection, reduce the interference of ambient light, improve the clarity and visibility of the picture, and allow viewers to enjoy better visual effects. AG glass can not only beautify the appearance and structure of decorations, but also widely used in TV splicing walls, TVs, LCD monitors, touch screens and industrial instruments. At present, there are two main technologies for producing AG glass in the market: coating method and chemical etching method. The former is less reliable due to the large investment and the film layer is easily affected by the external envir...
