Compound vacuum glass

Abstract

The invention discloses compound vacuum glass, comprising upper-layer flat plate glass, lower-layer flat plate glass and toughened glass, wherein the lower-layer flat plate glass is arranged between the upper-layer flat plate glass and the toughened glass; the vacuum glass is formed by the upper-layer flat plate glass and the lower-layer flat plate glass; the lower-layer flat plate glass is exposed from the peripheries of the upper-layer flat plate glass and the toughened glass; a plurality of supporting columns, which are uniformly arrayed, are arranged between the upper-layer flat plate glass and the lower-layer flat plate glass; a connecting piece made of the glass is spliced between the peripheries of the upper-layer flat plate glass and the toughened glass; the connecting piece is stuck with the upper-layer flat plate glass and the toughened glass through a photosensitive adhesive, so that the upper-layer flat plate glass and the toughened glass are firmly sealed together and a phenomenon of leaking gas is not generated; gas and water cannot enter a hollow layer and water fog is not generated, so that the visual effect is good; and each part of the compound vacuum glass has one color and the vision effect is good.

Description

technical field [0001] The invention relates to a vacuum glass, in particular to a composite vacuum glass, which belongs to the technical field of glass manufacturing. Background technique [0002] Existing composite vacuum glass is usually formed by a vacuum layer and a hollow layer. Install a piece of flat glass on one side of the vacuum glass, and an aluminum alloy frame is bonded between the flat glass and the vacuum glass, and then use hollow glass glue to seal the aluminum alloy frame, flat glass, and vacuum glass together from the outside of the aluminum alloy frame . [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art. In the production process of vacuum glass, the aluminum alloy frame, flat glass and vacuum glass are generally sealed by manual operation with hollow glass glue, which is easy to The seal is not tight, and, after a long time of use, the aging of the hollow gla...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art. In the production process of vacuum glass, the aluminum alloy frame, flat glass and vacuum glass are generally sealed by manual operation with hollow glass glue, which is easy to The seal is not tight, and, after a long time of use, the aging of the hollow glass glue will also cause the seal to be not tight

Due to thermal expansion and contraction, the insulating layer glass will breathe. Air and moisture can easily enter the hollow layer, and the moisture in the hollow layer is not easy to come out. In winter, water mist will form on the inner surface of the insulating layer glass, affecting the visual effect.

Furthermore, the current insulating glass glue is black, and it is sealed with black insulating glass glue, forming a black frame around the composite vacuum glass, which affects the appearance
