Locally anti-dazzle processing process of glass and product thereof

Abstract

The invention discloses a locally anti-dazzle processing process of glass. The process comprises the following steps: firstly covering the part which does not need anti-dazzle treatment on the surface of to-be-treated glass with an acid-resistant impact-resistant protective layer; then impacting silicon carbide sands which are over 2000 meshes by using compressed air to the surface of the glass which is not covered by the acid-resistant impact-resistant protective layer, wherein the sand spray time is 30-60 minutes; and after sand spray, putting the sprayed glass into a 10-25% strong acid mixed solution to etch for 25-30 minutes. The process is simple to operate and refine in step and fully satisfies the technique requirements of optical level flat panel display and subtle touch of a touch screen.

Description

technical field [0001] The invention relates to a glass surface treatment process, in particular to a glass partial anti-glare processing process. Background technique [0002] In our daily life, we all have the experience of being attacked by dazzling glare, partly from the glare light source, and partly from the reflection of glare: for example, when we operate a computer, we often cannot see the displayed content clearly because of the reflection of the scenery outside the monitor on the monitor surface And trouble; another example is that a layer of cover glass will be added on many LCD screens for protection, and the surrounding edges of these cover glass will be exposed outside. Since the glass cover is processed by mechanical cutting and edging, the surrounding edges are very If it is smooth, the light on the display screen will shine through the edge of the glass to form a dazzling edge light line. These are all caused by light reflection on the glass surface. To r...

Problems solved by technology

The disadvantages of these anti-glare glasses are: the glass surface is not corrosion-resistant, the anti-scratch performance is poor, after a long time of use, it will wear and shine, the coating layer will fall off or change color, and many problems will affect the appearance of the product.

Not only the process steps are cumbersome, but the most important thing is that the frosting paste used in the etching in the technical solution can only achieve the roughening of the glass surface, which will lead to the formation of uneven spots and blocks on the glass surface after etching, and the transparency is low. Then choose 1600-2000 mesh sandblasting silicon carbide sand for sandblasting, and make the glass surface rougher

The anti-glare surface of the glass produced by the method disclosed in this patent has low precision and cannot meet the technical requirements of optical-grade flat display and touch screen subtle tactility
