Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. In addition, those skilled in the art can make corresponding combinations of features in the embodiments in this document and in different embodiments according to the descriptions in this document.

[0043] An example of the present invention is as follows, a method for preparing composite glass with built-in airgel, comprising the following steps:

[0044] (1) sealing and welding the lower surface of the spacer 3 to the surface near the edge of a piece of glass 1 by using the low-temperature sealing material 4 while heating until melting, so as to obtain an open glass cavity;

[0045] (2) Then fill the airgel support body 2 in the glass cavity;

[0046] (3) Another piece of glass 1 is covered on the glass cavity, a...

Abstract

The invention provides composite glass internally provided with aerogel. The composite glass comprises a glass sealing body and a vacuum air pumping device arranged on the glass sealing body; the glass sealing body is composed of two pieces of glass, a spacing body between the two pieces of glass, and an aerogel supporting body arranged in a glass cavity; and the upper surface and the lower surface of the spacing body are connected with the two pieces of glass through low-temperature sealing-in materials. A preparation method of the composite glass comprises the following steps of (1) manufacturing of the glass cavity, filling of the supporting body, welded sealing and vacuumizing. The composite glass internally provided the aerogel has the good heat insulation property and the good lighttransmitting property, and is suitable for the fields of door windows, curtain wall glass, daylighting roofs and the like of environment-friendly buildings, ultra-low energy consumption buildings andnear-zero energy consumption buildings.

Description

technical field [0001] The invention relates to the technical field of glass preparation, in particular to a built-in airgel composite glass and a preparation method thereof. Background technique [0002] The glass used for buildings in the prior art is mainly used for sealing, daylighting and heat preservation. However, in winter in cold regions, the thermal insulation effect of glass is not ideal, and in summer in hot summer and cold winter regions or hot summer and warm winter regions, the thermal insulation effect of glass is not ideal. With the rapid development of my country's economy, people's requirements for quality of life are getting higher and higher, and the area of ​​building doors, windows, and glass curtain walls is getting larger and larger, resulting in an increasing proportion of heat exchange through doors, windows, and glass curtain walls in the heat exchange between buildings and the outside. bigger. In order to reduce the heat exchange through glass d...
