Method for producing vacuum glass by using 3D (three dimensional) printing technology and use of vacuum glass

Abstract

The invention discloses a method for producing vacuum glass by using a 3D (three dimensional) printing technology. The method comprises the following steps: placing two pieces of flat glass with a same size into a toughening furnace to be toughened or placing into a bending toughening furnace to be bent and toughened, and obtaining flat or curved toughened glass; (2) arranging supports in a dot matrix arrayed manner on the surface of one piece of the toughened glass by using the 3D printing technology; (3) placing the other piece of the toughened glass onto the supports and aligning the toughened glass with the toughened glass with the supports in step (2); (4) pouring an edge-sealing material to the periphery of a gap between the two pieces of toughened glass, rapidly heating and curing the edge-sealing material, and encapsulating edge portions of the two pieces of toughened glass; and (5) extracting air between the two pieces of toughened glass by virtue of extractor vents to form a vacuum cavity between the two pieces of toughened glass, rapidly sealing the extractor vents by virtue of infrared heating or laser radiation, and completing the preparation of the vacuum glass. The displacement of the supports in a subsequent processing process is avoided; the requirement on the temperature resistant performance 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 a method for arranging vacuum glass supports by 3D printing technology. Background technique [0002] Vacuum glass is a closed vacuum chamber formed between two pieces of glass, which achieves multiple functions such as heat insulation and moisture reduction, and noise reduction. In order to form a stable vacuum cavity between the two pieces of glass, it is necessary to make a support point between the two pieces of glass to withstand the external pressure. At present, the supporting points are generally evenly dispersed on the glass surface, and then the supporting points are fixed on the glass surface. For example, Chinese patent CN2010101159835 discloses a production process of tempered glass, which adopts the screen printing method to uniformly disperse the glass frit on the flat glass. On the surface, the glass glaze is naturally dried or dried ...

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.
