An energy-saving, heat-insulating, UV-resistant building curtain wall glass

Abstract

The invention discloses energy-saving, thermal-insulation and anti-ultraviolet building curtain wall glass. The building curtain wall glass comprises a first glass substrate on the outer side, a second glass substrate in the middle and a third glass substrate on the inner side, wherein an anti-ultraviolet coating is arranged on the outer surface of the first glass substrate, a silicon dioxide aerogel layer is arranged between the first glass substrate and the second glass substrate, and a transparent conductive film layer is arranged between the second glass substrate and the third glass substrate and connected with a controller; the anti-ultraviolet coating is prepared from, in parts by weight, 3.8-6.4 parts of dimethyl formamide, 5.1-8.6 parts of polyurethane, 2.2-4.5 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate and 0.03-0.12 parts of nano-alumina. The curtain wall glass has the characteristics of being good in thermal insulation and anti-ultraviolet effects, adjustable in light transmission and capable of protecting privacy without a curtain.

Description

technical field [0001] The invention relates to a building curtain wall glass, in particular to an energy-saving, heat-insulating and ultraviolet-proof building curtain wall glass. Background technique [0002] Architectural curtain wall glass is a kind of glass installed on the periphery of the building. It has the characteristics of high structural strength. However, in the actual application of architectural curtain wall glass, in addition to the requirements for strength, because it is directly used as a curtain wall, its light transmittance , heat insulation, anti-ultraviolet, etc. have high requirements, but the heat insulation and anti-ultraviolet function of the current building curtain wall glass are poor, which cannot meet the needs of use. In addition, because of its good light transmission, in When users need to protect the privacy of the building, they need to use curtains and other devices, which are inconvenient. At the same time, after the curtains are closed...

[0002] Architectural curtain wall glass is a kind of glass installed on the periphery of the building. It has the characteristics of high structural strength. However, in the actual application of architectural curtain wall glass, in addition to the requirements for strength, because it is directly used as a curtain wall, its light transmittance , heat insulation, anti-ultraviolet, etc. have high requirements, but the heat insulation and anti-ultraviolet function of the current building curtain wall glass are poor, which cannot meet the needs of use. In addition, because of its good light transmission, in When users need to protect the privacy of the building, they need to use curtains and other devices, which are inconvenient. At the same time, after the curtains are closed, the house cannot receive natural light, so it loses the function of installing glass curtain walls, which also cannot satisfy the needs of users. need
