Coated hollow composite glass and manufacturing method thereof

Abstract

Disclosed are coated hollow composite glass and a manufacturing method thereof. The coated hollow composite glass comprises an upper glass substrate, a lower glass substrate, a spacer frame and hollow filling, wherein the spacer frame is respectively and peripherally adhered to the upper glass substrate and the lower glass substrate and gaps among the spacer frame, the upper glass substrate and the lower glass substrate are sealed via sealant, a hollow cavity is enclosed by the upper glass substrate, the lower glass substrate and the spacer frame, the hollow filling is filled into the hollow cavity, the hollow filling is a honeycombed board, and aerogel is filled into cells of the honeycombed board. The manufacturing method includes steps of pretreating the upper glass substrate and the lower glass substrate, preparing the middle filling, attaching the spacer frame, filling with the hollow filling and attaching the lower glass substrate. The coated hollow composite glass and the manufacturing method can meet the construction requirement and the energy-saving requirement of public buildings, and the coated hollow composite glass has good thermal insulation property.

Description

technical field [0001] The invention relates to a coated glass, in particular to a heat-insulating airgel coated hollow composite glass and a manufacturing method thereof. Background technique [0002] Green energy saving is a concept vigorously advocated by the state at present, and my country's building energy consumption accounts for about 1 / 3 of energy consumption. In building energy consumption, daylighting glass windows and daylighting roofs account for about 50% of the total energy consumption. At present, the main energy-saving solution is to use coated insulating glass, and the coating mostly uses low-emissivity coated glass to achieve the purpose of heat insulation. Low-emissivity coated glass is mainly coated with one or more layers of oxide film and functional metal layer on the surface of off-line glass, so that it has low reflectivity for near-infrared radiation and high reflectivity for far-infrared rays, and can maintain its good light transmission performan...

Problems solved by technology

But it also has its limitations. The most important thing is that simply filling the airgel into the hollow cavity cannot solve the settlement phenomenon after long-term use of the substance. At the same time, airgel is a brittle substance. It needs to go through the processing process of transportation, framing, hoisting and installation, which can easily cause powdering and damage of unprotected airgel

The application number is "201110046646", and the name is "Integrated Transparent Thermal Insulation SiO 2 Airgel composite glass and its preparation method” Chinese invention patent application discloses a design method and preparation method for the integration of airgel and insulating glass, but the above-mentioned hollow products cannot meet the needs of high-end products such as large-area curtain walls , its bonding method cannot withstand the shear force and wind pressure resistance required by large-area insulating glass, and at the same time it cannot realize the filling of large-area insulating glass, and the size of processing and implementation has its inherent limitations
