Problems solved by technology

However, due to SiO 2 Airgel has low strength and high brittleness, so it is filled with SiO 2 When using an airgel plate, on the one hand, the contact part is often unable to be filled densely. Because there is a gap between the glass and the airgel, there is a heat transfer phenomenon caused by convection, which reduces the thermal insulation properties of the glass, and when the performance of the sealant is not good. Condensation will also occur in winter; on the other hand, it is easy to cause airgel damage during assembly or transportation

Abstract

The invention discloses a building energy-saving glass. The building energy-saving glass comprises two glass sheets and a seal spacer positioned between the two glass sheets, a closed cavity is formed among the seal spacer and the glass sheets, transparent heat insulation SiO2 aerogel plates are filled in the closed cavity, a transparent SiO2 aerogel aqueous rubber is used to seal the transparent heat insulation SiO2 aerogel plates, and a butyl rubber is used to seal the seal spacer and the glass sheets. Convection heat loss and condensation phenomena caused by air transmission are greatly reduced, so compared with a hollow glass and a low-irradiation hollow glass in the prior art, the energy saving glass filled with the transparent heat insulation SiO2 aerogel plates has a high heat insulation performance and simultaneously has a high light transmission rate; and the energy saving glass has a heat insulation performance near to that of a vacuum glass, and has a substantially higher service life than the vacuum glass.

Description

technical field [0001] The invention relates to a building energy-saving glass. Background technique [0002] For the severe cold and cold regions in northern my country, the heating period in winter is long, and a large amount of energy needs to be consumed to meet the heating demand. In the building envelope structure in northern my country, although the area of ​​external doors and windows accounts for about 20-30% of the entire building envelope, the energy consumption through external doors, windows or glass curtain walls has exceeded more than 50% of the energy consumption of the entire building envelope. . The solutions of prior art mainly contain following several kinds: [0003] (1) Insulating glass composed of two or more layers of glass, filled with dry air or inert gas in the middle; [0004] (2) Low-emissivity coated insulating glass composed of insulating glass coated with low-emissivity coating and heat-insulating film glass; [0005] (3) Insulating glass i...
