Etching solution for antiglare glass and preparation method thereof

Abstract

The invention discloses an etching solution for antiglare glass and a preparation method thereof, and relates to antiglare glass. Raw materials of the etching solution for the antiglare glass comprise the following components in mass ratio: ammonium hydrogen fluoride and hydrochloric acid which are in a mass ratio of 5 to (2 to 4), wherein the mass percentage concentration of the hydrochloric acid is 31 to 36 percent. The preparation method of the etching solution for the antiglare glass comprises the following steps of mixing the ammonium hydrogen fluoride with the hydrochloric acid, and curing an obtained mixture, so as to subsequently obtain a product. The defects, that the etching is not uniform, the specific gravity is large, light leaks, a blocky dapple and a current trace are generated, the granularity of the surface of the glass is rough and is not less than 0.15 micron, impurities are many, the purity is insufficient, and the like, existing in an existing etching solution for the antiglare glass are solved. The transformation from an antiglare light reflecting ratio between 0.5 percent and 9 percent can be breezily realized; the finished-product rate is up to 98 percent or above without through multiple other chemical additions any more. The content of acid liquor is few; components are few; discharged water is easily treated; the discharge of sewage easily reaches a standard; the glossiness is 8 to 125 percent; the transmissivity is 5 to 93 percent; the reflection coefficient is 0.5 to 10 percent. The antiglare glass can be used for a television, various instruments, a mobile phone and the like.

Description

technical field [0001] The invention relates to antiglare glass, in particular to an antiglare glass etchant and a preparation method thereof. Background technique [0002] Anti-glare glass, also known as non-reflective glass or anti-reflective glass, is a special surface treatment of the glass substrate, so that it has a lower reflectance than ordinary glass, and basically does not affect the transmission of light. From 8% to below 1%. Anti-glare glass can improve the viewing angle and brightness of the display screen, making the image clearer, the color more vivid, and the color more saturated, thereby significantly improving the display effect. It can be widely used in the production of LCD screens, rear projection TVs, education machine screens, mobile phone covers, electronic photo frames, and instrument display panels.

Problems solved by technology

[0003] Existing anti-glare glass generally uses methods such as glass surface coating or etching with high-depth acid solution, but the method of etching with high-depth acid solution has the following disadvantages in addition to the need for high-depth acid solution: etching is not easy Uniformity, heavy specific gravity, light leakage, blocky mottling, water flow traces, rough glass surface particle size, ≧0.15μm, many impurities, insufficient purity
