Problems solved by technology

The traditional frosted glass preparation process uses the process of spraying resin to achieve the anti-glare effect on the glass surface. The frosted glass realized by this physical spraying process has defects such as easy aging, easy scratching, poor adhesion, and short life cycle. And the cost is high, the production capacity is low, and it is difficult to meet the needs of the current smart phone back cover
Frosted glass etched by other frosting liquids have the disadvantages of average hand feeling, uncharacteristic iterative products, and single effect, which cannot meet the increasing requirements of modern consumers.

Abstract

The invention belongs to the technical field of glass etching, and discloses glass frosting liquid with an AG effect as well as preparation and application of the glass frosting liquid. The frosting liquid comprises the following components in percentage by weight: 25-30% of fluoride, 25-30% of acid, 12-16% of inorganic salt and the balance of water. According to the AG glass treated by the frosting liquid, surface crystals are regularly distributed, the roughness is 0.8-1.5 microns, the haze is greater than 60%, the light transmittance is greater than 80%, and the micromorphology is large maple-leaf-shaped microcrystal particles and is a microcrystal form obviously different from that of other existing products on the market; correspondingly, different visual effects are presented macroscopically, and the texture is similar to that of leather; different from the microcosmic polyhedral form of AG glass prepared from the flashing sand frosting liquid in the market, the AG glass treated by the frosting liquid disclosed by the invention has the advantages of smaller roughness, better anti-falling performance, low haze and higher glass permeability.

Description

technical field [0001] The invention belongs to the technical field of etching glass, and particularly relates to a novel glass frosting liquid with AG effect and its preparation and application. Background technique [0002] As smart reading becomes more and more fashionable, consumers have higher and higher requirements for the appearance and feel of electronic products, and the demand for more novel back cover glass with anti-scratch, anti-fingerprint, anti-glare effects, and more has increased significantly. The traditional frosted glass preparation process adopts the process of spraying resin to achieve the effect of anti-glare on the glass surface. The frosted glass realized by this physical spraying process has defects such as easy aging, easy scratching, poor adhesion, and short life cycle. In addition, the cost is high and the production capacity is low, which makes it difficult to meet the current demand for the back cover of smartphones. The frosted glass etched ...
