Preparation method and application of vacuum glass

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...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages of the prior art, to find a method for making a plane or arc-shaped vacuum glass, and to solve the problems of complicated support point fixing process and high performance requirements of support point materials in the existing vacuum glass production process. The arc-shaped vacuum glass has high safety performance and avoids the frost and condensation phenomenon that occurs when the existing automobile glass is used.
