Embodiment Construction

[0023] The technical solution of the present invention will be introduced in detail below in conjunction with the accompanying drawings and embodiments

[0024] combine figure 1 with figure 2 As shown, Gorilla Glass 3 glass with a thickness of 0.6mm is selected as the glass body from Corning Corporation, and the method for preparing curved glass of the present invention is introduced in detail. The specific operation steps are as follows:

[0025] Step S1, setting a protective layer on the outside of the glass body. A sheet material having a thermal bending performance similar to that of the glass body 1 and having a certain thickness is selected as the protective layer 2 , and the sheet material is laid flat on the surface of the glass body 1 .

[0026] Preferably, in this embodiment, according to the selected mold and the pre-statistical analysis of the depth of hot bending defects, Corning's Gorilla Glass 3 with a thickness of 0.2 mm is selected as the protective layer. ...

Abstract

The invention belongs to the technical field of preparation of curved glass and specifically relates to a preparation method of the curved glass. In order to solve the problems of low preparation efficiency and poor quality caused by the defects of a glass body in a preparation process when the curved glass is prepared by adopting a hot bending process, the invention discloses the preparation method of the curved glass. The preparation method comprises the following steps: step S1, arranging a protection layer at the outer part of the glass body; step S2, performing hot bending on the glass body; step S3, eliminating the protection layer, so as to obtain the curved glass finally. The curved glass is processed and prepared by adopting the preparation method, so that the preparation efficiency of the curved glass is improved, and the quality of the finally obtained curved glass is also enhanced.

Description

technical field [0001] The invention belongs to the technical field of curved glass preparation, and in particular relates to a method for preparing curved glass. Background technique [0002] In the existing curved glass, the flat glass is passed through a mold or machine equipment, and after being processed with a mold or a cutting tool, the finished product is made into a glass plate with a curved curvature. Among them, glass hot bending with the help of molds is currently the most commonly used process for preparing curved glass. [0003] During the actual processing of curved glass using glass hot bending technology, it is found that due to the influence of high temperature and high pressure and processing errors on the surface of the mold when the glass body is formed, it is very easy to cause defects on the surface of the glass body, such as pitting , indentation, scratches and other problems, at this time, it is necessary to use the subsequent grinding process to de...
