Vacuum glass with self-regulating flatness and manufacturing method thereof

Abstract

The invention relates to vacuum glass of automatic flatness adjustment and a preparation method thereof, which comprises upper plate glass, basal board glass, supporters and a low melting-point glass powder sealed edge, wherein supporters are uniformly arranged between the upper plate glass and the basal board glass at intervals and are rigid supporters, and a layer of low melting-point glass powder is uniformly wrapped on the outer edge of every rigid supporter. The rigid supporters of the invention combine soft support and rigid support into a whole, the partial stress problem and the supporter sliding problem of metal fixing supporters are overcome, the technical steps of the vacuum glass are reduced, and the low melting-point glass powder wrapped on the rigid supporters can be used for automatically adjusting the flatness of the vacuum glass, the quality of the vacuum glass is guaranteed, the production cost is lowered, and the development of the vacuum glass industry is promoted. The invention is particularly suitable for the industrialized, the scale and the standardized production of the vacuum glass.

Description

technical field [0001] The invention belongs to the field of vacuum glass, in particular to a self-adjusting flatness vacuum glass and a preparation method thereof. Background technique [0002] The sound insulation, heat insulation and thermal insulation properties of vacuum glass are much better than ordinary glass or interlayer glass, and its application prospect is very broad. However, the existing vacuum glass preparation process is very complicated, the production efficiency is low, and the reject rate is high, resulting in high production cost and high sales price, which seriously affects the production of vacuum glass and restricts the wide application of vacuum glass. The existing vacuum glass preparation process mainly includes: 1. On the substrate glass, the low-melting point glass powder support is evenly distributed and bonded at intervals. The purpose of fixedly supporting the upper glass and the substrate glass; 2. Arranging metal fixed supports on the substr...

AI Technical Summary

Problems solved by technology

In the above-mentioned prior art, it is indispensable to set a metal fixed support, but because the material properties of the vacuum glass material and the metal fixed support are different, the two have a large difference in expansion coefficient, and the flatness and thickness of the flat glass itself are difficult. It is difficult to control the consistent height, which often causes local stress on the vacuum glass at the position of the metal support, resulting in cracks and cracks in the vacuum glass, and the sliding displacement of some metal supports due to the different gaps between the glasses, which affects The quality of the vacuum is reduced, and the yield of vacuum glass is reduced
