Abstract
A method for manufacturing and processing a flexible glass product comprises the following steps; step one; attaching the glass raw material to the carrier plate I through the adhesive composition, so that the glass raw material and the carrier plate I are fixed; step two; carrying out chemical etching thinning and/or physical grinding and polishing on the fixed glass raw material and the carrier plate I to thin the glass raw material to a specified thickness, and removing surface appearance defects of the glass raw material to obtain flexible glass fixed by the carrier plate I; step three; laminating one or more pieces of flexible glass fixed by the carrier plate I with the carrier plate II through the bonding composition, and then cutting and CNC (computer numerical control) molding to obtain the flexible glass I fixed by the carrier plate II; step four; the flexible glass I fixed by the carrier plate II is subjected to ultraviolet irradiation and/or heating treatment to separate the carrier plate I and the carrier plate II from the flexible glass, so that the flexible glass I is obtained; step five; and D, tempering the flexible glass I obtained in the step four to obtain a flexible glass product.
Description
Technical Field
The invention relates to the technical field of flexible glass, in particular to a manufacturing and processing method of a flexible glass product.
Background
The flexible glass product is the development direction of ultra-thin glass in recent years, has good bendable and flexible performance, and meets the requirements of intellectualization and lightness and thinness of electronic products.
According to the research at home and abroad, the main preparation methods of the existing flexible glass product (generally, the thickness is between 10 and 200 um) are two:
firstly, the direct forming method heats and melts all components for manufacturing glass, and then directly manufactures the flexible glass with the appointed thickness by adopting a float method/overflow method, but in the batch production, the method is mainly used for manufacturing the glass with the thickness more than 100um, has high cost and is not easy to manufacture in a large area;
second, the thinning method thins the thicker glass to the flexible glass with the designated thickness by a liquid etching method such as HF or a grinding/polishing method. The method has low cost and can be manufactured in a large area, but the glass is very easy to crack in the manufacturing process because the target thickness of the glass thinning is very thin;
and secondly, the processing of the flexible glass product mainly comprises cutting, surface micro-etching, surface grinding and polishing, CNC forming, edge polishing, edge etching, tempering and the like. The flexible glass is thin and has the characteristic of being fragile before tempering.
Disclosure of Invention
The invention aims to solve the technical problem of providing a manufacturing and processing method of a flexible glass product.
In order to solve the technical problem, the invention adopts the following technical scheme:
a method for manufacturing and processing a flexible glass product comprises the following steps;
step one; attaching the glass raw material to the carrier plate I through the adhesive composition, so that the glass raw material and the carrier plate I are fixed;
step two; carrying out chemical etching thinning and/or physical grinding and polishing on the fixed glass raw material and the carrier plate I to thin the glass raw material to a specified thickness, and removing surface appearance defects of the glass raw material to obtain flexible glass fixed by the carrier plate I;
step three; laminating one or more pieces of flexible glass fixed by the carrier plate I with the carrier plate II through the bonding composition, and then cutting and CNC (computer numerical control) molding to obtain the flexible glass I fixed by the carrier plate II;
step four; the flexible glass I fixed by the carrier plate II is subjected to ultraviolet irradiation and/or heating treatment to separate the carrier plate I and the carrier plate II from the flexible glass, so that the flexible glass I is obtained;
step five; and D, tempering the flexible glass I obtained in the step four to obtain a flexible glass product.
Further, the adhesive composition includes a pressure-sensitive type, a thermosetting type, a UV curing type, a two-liquid mixing curing type adhesive.
Further, the adhesive composition includes a composition mainly composed of a photo-shrinkable/expandable resin.
Further, the adhesive composition includes a composition using a heat shrinkable/expandable resin as a main body.
Further, the chemical etching thinning mode comprises a soaking mode, a spraying mode and a horizontal spraying mode, and the etching liquid adopts one or more of hydrofluoric acid, fluosilicic acid, ammonium fluoride, ammonium bifluoride, hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, oxalic acid, citric acid, tartaric acid and sulfamic acid to react with the glass raw material for etching thinning.
