Problems solved by technology

The main way for the existing manufacturers to solve the problem of interference flash point on the glass is to increase the gloss of the anti-glare glass; during implementation, the gloss of the anti-glare glass at a 60° angle under normal conditions is raised to 100 from 40 to 85 SGU ~120SGU, although this method solves the problem of interference flash point, but with the increase of gloss, it seriously affects the anti-glare effect of the glass, making the glass lose the anti-glare function

Embodiment 1

[0031] Such as figure 1 , figure 2 , image 3 As shown, the non-interference flash point anti-glare glass described in this embodiment includes a glass substrate 1, the glass substrate 1 has a light incident surface 11, and the light incident surface 11 is the side close to the display screen during application. The other side of the glass substrate 1 opposite to the light incident surface 11 is a light exit surface 12. The light exit surface 12 of the glass substrate 1 is a rough surface with a concave-convex structure formed by etching. The surface roughness of the light exit surface 12 is defined as follows : Ra is in the range of 0.06-0.18 μm, Rsm is in the range of 15-40 μm, Rz is in the range of 0.65-1.5 μm; the glossiness of the light exit surface 12 at an angle of 60° is in the range of 45-85 SGU. The transmittance of the glass substrate 1 is in the range of 83-94%. The haze of the glass substrate 1 is in the range of 5-19%. The clarity of the glass substrate 1 is...

Embodiment 11

[0045] This embodiment provides a method for preparing a glass frosting etching solution, and the preparation steps of the frosting etching solution are as follows:

[0046] Step 1: Stir and fuse 8 parts by weight of ammonium bifluoride, 2 parts of calcium fluoride, 3 parts of potassium chloride and 6 parts of water, then add 3 parts of potassium fluoride solution, and stir and mature for 4 hours;

[0047] Step 2: Pour the matured frosting etching solution obtained in step 1 into the liquid medicine tank equipped with horizontal spraying equipment, and use an acid-resistant pump to circulate and filter to make the frosting etching solution fully react, and then stir for 38 minutes;

[0048] Step 3: Filtration; the frosting etching solution obtained in step 2 is filtered with 80 mesh screen cloth in the tank, and the saturated crystals are isolated outside the extraction area of ​​the acid-resistant pump, thereby obtaining the frosting etching solution with a pH value of 5.5. F...

Embodiment 12

[0052] The difference between this embodiment and Example 11 is that in step two of this embodiment, 9 parts by weight of ammonium bifluoride, 3 parts of sodium fluoride, 2 parts of calcium fluoride, 4 parts of potassium chloride and 6.5 parts of water Stir and fuse, then add 4 parts of potassium fluoride solution, and stir and mature for 5h.

[0053] The roughness parameters and optical characteristics of the glass etching surface etched by the frosting etching solution of this embodiment are those shown in Embodiment 3.

Abstract

The invention relates to interference-flash-point-free anti-dazzle glass. The glass is characterized by comprising a glass substrate, wherein the glass substrate is provided with a light-in surface, and the other side face, opposite to the light-in surface, of the glass substrate is a light-out surface; the light-out surface of the glass substrate is processed through etching to form a rough surface with a concave-convex structure; according to the definition of surface roughness of the light-out surface, Ra is in the range of 0.06-0.18 micrometer, Rsm is in the range of 15-40 micrometer, andRz is in the range of 0.65-1.5 micrometers; the glossiness of the 60-degree angle of the light-out surface is in the range of 45-85 SGU. The glass has the advantages that the glass is simple in structure, good in wear resistance and long in service life, the glossiness of existing anti-dazzle glass can be kept, and no interference flash point appears during application. The invention further relates to a preparation method of a glass frosting etching solution and a production technology of the interference-flash-point-free anti-dazzle glass.

Description

technical field [0001] The present invention relates to a glass plate, especially a non-interference flash point anti-glare glass; the present invention also relates to a preparation method of glass frosting etching solution; the present invention also relates to the production of a non-interference flash point anti-glare glass craft. Background technique [0002] In order to prevent external side light sources from interfering with reflected strong light on the screen of electronic products and affecting the user's visual recognition, existing electronic products generally have an anti-glare cover on the screen to reduce the intensity of externally reflected light. At present, there are two ways of anti-glare treatment in the industry: one is to spray anti-glare film on the surface of the glass. The anti-glare film is made of resin material, which has poor wear resistance and has the disadvantage of short service life. The other is to chemically etch the surface of the gla...
