AI Technical Summary

Problems solved by technology

For example, ordinary hollow and vacuum glass have a small radiation barrier rate and poor heat insulation effect in summer; vacuum glass is prone to self-explosion when the temperature difference between indoor and outdoor is large; coated glass is easy to be oxidized and loses heat insulation and energy saving effects, etc.
Three glass windows with two chambers have been adopted in some areas of our country. Although the heat transfer coefficient is further reduced, the radiation barrier is still small, and the weight of the window is increased, which has higher requirements for the load bearing of the window frame and the building. It also increases the difficulty of construction

Abstract

The invention discloses hollow two-cavity or multi-cavity nanometer composite energy-saving glass, which comprises two pieces of glass, one or more than one transparent nanometer composite sheet material, glass press strips and sealant, wherein the transparent nanometer composite sheet material is clamped in an air layer between the two pieces of glass by the glass press strips, and divides the air layer between the two pieces of glass into two or more than two parts. The high-transparency high-heat-isolation anti-ultraviolet energy-saving nanometer composite sheet material is used for being clamped in the middle of the air layer of the hollow glass and dividing the air layer of the hollow glass into two or more than two parts, so that the heat transmission coefficient K value of window glass is obviously reduced; meanwhile, the sun shading coefficient S<C> value of the window glass is reduced; and the comprehensive energy-saving goal is achieved.

Description

technical field [0001] The invention relates to the technical field of glass windows, in particular to a hollow two-cavity or multi-cavity heat-insulating energy-saving glass and a manufacturing method thereof. Background technique [0002] With the rapid development of society, more and more attention has been paid to energy issues. With the vigorous promotion of national energy conservation and emission reduction policies, my country has further intensified the application of energy-saving materials in new buildings and the energy-saving renovation of existing buildings. Among them, glass doors and windows, as the thin-walled enclosure structure in the building, play the functions of lighting and ventilation. However, just because of the particularity of glass as a material, it has become a relatively large energy-consuming link in construction. It has been demonstrated by many authoritative organizations that the energy lost through glass doors and windows has accounted ...
