Embodiment 1

[0028] A kind of manufacturing method of the vacuum glass that this embodiment relates to specifically comprises the following steps:

[0029] (1) Tempering: Put two pieces of flat glass of the same size into a tempering furnace for tempering to obtain flat tempered glass;

[0030] (2) Setting up the support: (A1) Cover the pre-designed position of the support, the reverse side of the glass, and the side of the glass on the front of a piece of tempered glass with a protective material that is resistant to hydrofluoric acid or sodium natrium; (A2) put the hydrofluoric acid Put the acid or sodium hydroxide into the corrosion-resistant box or pool, heat the hydrofluoric acid or sodium hydroxide to a certain temperature, put the tempered glass into the box or pool with corrosion-resistant lifting tools, and The glass surface is chemically corroded until the part of the tempered glass that is not covered with the protective material is corroded to a thickness of 0.1-0.3mm to termin...

Embodiment 2

[0039] A kind of manufacturing method of the vacuum glass that this embodiment relates to specifically comprises the following steps:

[0040] (1) Tempering: Two pieces of flat glass of the same size are put into a bending tempering furnace for bending and tempering to obtain the same two pieces of curved tempered glass. One of the flat glasses is low-emissivity glass (LOW-E glass), low-emission Glass is formed by coating LOW-E film on the original glass sheet;

[0041] (2) Set up the support: (A1) Set the laser irradiation temperature, operating speed and transmission thickness according to the power of the laser generator; (A2) Laser the other parts of the glass surface except the support according to the set thickness For cutting, the height of the support is the thickness of laser cutting; further, the thickness of laser cutting is 0.1-0.3mm, more preferably 0.15mm. (3) another piece of tempered glass is placed on the support and aligned with the tempered glass on which t...

Abstract

The invention discloses a preparation method of vacuum glass. The method comprises the steps of (1) placing two pieces of plain glass with same size into a tempering furnace for tempering or placing into a bending and tempering furnace for bending and tempering so as to obtain plain or curved tempered glass; (2) adopting a chemical corrosion way or a laser etching way for setting support objects arranged in a dot matrix way on the surface of one piece of tempered glass; (3) placing the other piece of tempered glass on the support objects, and aligning the tempered glass at the tempered glass provided with the support objects in the step (2); (4) filling an edging material around a gap between the two pieces of tempered glass, quickly heating and curing the edging material and accomplishing sealing side parts of the two pieces of tempered glass; (5) pumping air between the two pieces of tempered glass through an air pumping hole so as to form a vacuum chamber between the two pieces of tempered glass, and quickly sealing the air pumping hole through an infrared heating or laser radiation way so as to accomplish the preparation of the vacuum glass. The movement of the support objects during a subsequent processing process is avoided, the requirement on temperature resistance of the material is reduced, and the noise is reduced.

Description

technical field [0001] The invention belongs to the technical field of vacuum glass preparation, and in particular relates to the formation of a support integrated with one piece of glass in vacuum glass by using chemical corrosion technology or laser etching technology. The glass is suitable for building door and window glass and automobile glass. Background technique [0002] Vacuum glass is a closed vacuum cavity formed between two pieces of glass to achieve multiple functions such as heat insulation, moisture retention, and noise reduction. In order to form a stable vacuum cavity between the two pieces of glass, it is necessary to make a supporting point between the two pieces of glass to withstand the external pressure. At present, the support points are generally evenly dispersed on the glass surface, and then the support points are fixed on the glass surface. For example, Chinese patent CN2010101159835 discloses a production process of tempered glass, which uses a scr...
