Hollow glass internally provided with sunshading device

Abstract

The invention provides hollow glass internally provided with a sunshading device. The hollow glass comprises a cavity and the sunshading device in the cavity, wherein the cavity is constituted by twotransparent plates A and a sealing assembly A; the sunshading device comprises a plurality of sunshading blades, linkage parts and an angle linkage adjusting and lifting device; and the multiple sunshading blades are mutually connected through the linkage parts and mounted on the angle linkage adjusting and lifting device. The hollow glass is characterized in that the sunshading blades are each composed of a cavity and aerogel in the cavity, wherein the cavity is constituted by two transparent plates B and a sealing assembly B. The hollow glass internally provided with the sunshading device has the good heat-insulation and heat-preservation properties and the good light transmitting property and the adjustable solar heat gain coefficient, 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 and near-zero energy consumption buildings.

Description

technical field [0001] The invention relates to the technical field of glass preparation, in particular to a hollow glass with a built-in sunshade device and a preparation method thereof. Background technique [0002] Glass is an airtight material with high transparency, strength and hardness. Glass is chemically inert in the daily environment and will not interact with organisms. Therefore, it has a wide range of uses. The glass used for buildings in the prior art is mainly used for sealing and lighting. 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 building doors, windows, and glass curtain walls are getting bigger and bigger, resulting in an increasing proporti...

AI Technical Summary

Problems solved by technology

However, while the existing sunshade device blocks the sunlight, it will also cause a decline in the indoor lighting capacity, which is not conducive to indoor lighting.

Moreover, as my country's building energy-saving requirements become increasingly stringent, the heat insulation performance of existing heat-reflective coated glass and low-emissivity coated insulating glass has become more and more difficult to meet the requirements.
