Problems solved by technology

However, although the current glass with gradually changing haze achieves a gradient effect, the greater the haze of the glass, the stronger the diffuse reflection of light and the lower the light transmittance. In electronic equipment that requires high optical performance In application, especially when the glass with gradient haze is used as the cover plate of electronic equipment, it will be subject to many restrictions and cannot meet the requirements of use

Embodiment 1

[0038] Using aluminosilicate glass, the thickness is 0.6mm, the length is 160mm and the width is 75mm. Clean the glass, cover one side of the glass with acid-resistant ink, fix the A side of the glass, and lower the B side (the other side opposite to the A side) at a speed of 1.2mm / S until the glass is completely immersed in the frosting treatment liquid (ammonium bifluoride mass ratio of 25%, potassium fluoride mass ratio of 5%, and barium sulfate mass ratio of 8% aqueous solution), and then quickly pull out the liquid surface, and then wash with a large amount of water. The surface of the glass forms a gradient frosting effect, the surface roughness RA of the A end is 0.15 microns, and the haze is 35%. The percentage of the ratio of the scattered luminous flux Td at an angle of 2.5° to the luminous flux T2 passing through the gradient glass, the haze test method in this paper is the same), the surface roughness RA of the B-end is 0.35 microns, and the haze is 90%. Fix the B...

Embodiment 2

[0040] Using aluminosilicate glass, the thickness is 0.6mm, the length is 160mm and the width is 75mm. The glass is cleaned, and the whole glass is directly immersed in frosting acid solution (an aqueous solution with a mass ratio of 30% of ammonium bifluoride, 5% of potassium fluoride, and 8% of barium sulfate) to uniformly corrode the glass, and the surface roughness RA of the glass is 0.4 micron, 99% haze effect, wash and dry for later use. Fix the A side of the glass, and drop the B side (the other side opposite to the A side) at a speed of 0.12mm / S until the glass is completely immersed in the chemical polishing acid solution (aqueous solution containing 5wt% hydrofluoric acid and 2wt% sulfuric acid) , and then quickly pull out the liquid surface, and then wash with plenty of water. The surface roughness RA of end A is 0.36 micron, and the haze is 90%, and the surface roughness of end B is 0.1 micron, and the haze is 15%. Achieve uniform gradient etching on the entire s...

Embodiment 3

[0042] Using aluminosilicate glass, the thickness is 0.6mm, the length is 160mm, and the width is 75mm. The glass is cleaned, one side of the glass is covered with acid-resistant ink, the A side of the glass is fixed, and the B side (the other side opposite to the A side) is lowered at a speed of 1.2mm / S until the glass is completely immersed in the frosting treatment solution (ammonium bifluoride 30% by mass, 5% by mass of potassium fluoride, and 8% by mass of barium sulfate in an aqueous solution), and then quickly pulled out of the liquid surface, and then cleaned with a large amount of water. The surface of the glass forms a gradient frosting effect, the surface roughness RA of the A-end is 0.15 microns, and the haze is 35%, and the surface roughness RA of the B-end is 0.35 microns, and the haze is 90%. Then immerse the glass as a whole in a chemical polishing acid solution (containing 5wt% hydrofluoric acid and 2wt% sulfuric acid aqueous solution) for 10 minutes, the surf...

Abstract

The invention provides gradient glass and its preparation method and application. The gradient glass comprises: a glass body, the haze of at least a part of the outer surface of the glass body is greater than 0, the haze gradually changes in a predetermined direction, and the The light transmittance at any position of the glass body is greater than 85%. The gradient glass can achieve higher light transmittance while having a gradient effect, and can meet the requirements for use of electronic equipment, especially the use requirements for cover plates of electronic equipment, greatly expanding the application range of the gradient glass.

Description

technical field [0001] The invention relates to the technical fields of glass and electronic equipment, and in particular, to gradient glass and its preparation method and application. Background technique [0002] With the rapid development of electronic equipment, people put forward higher and higher requirements on the performance and appearance of the electronic equipment. At this stage, in order to avoid the signal shielding problem of metal shells, more and more glass shells are applied to electronic equipment shells, and in order to meet the different needs of users for fashion and personality, a variety of glass shells have been developed. The glass housing with decorative effect, among which, the glass with gradient haze is favored by many users. However, although the current glass with gradually changing haze achieves a gradient effect, the greater the haze of the glass, the stronger the diffuse reflection of light and the lower the light transmittance. In electro...
