Abstract

The invention provides an aerogel composite glass preparation method, wherein the aerogel composite glass comprises a core part and a surface layer, the core part is a composite body formed by an aerogel and a glass phase adhered to the aerogel, and the surface layer is the glass phase. The manufacturing method comprises: (1) preparing a glass melting liquid; (2) preparing a mixed glass melting liquid; (3) pre-molding; (4) preparing an aerogel composite glass; and (5) annealing. According to the present invention, with the manufacturing method, the resources of the float glass production lineare completely utilized, the synchronous online production of the float glass and the aerogel composite glass can be achieved by adding the aerogel online and mixing with the glass melting liquid, andthe prepared aerogel composite glass has advantages of good heat insulation performance, good light transmittance, good safety, good sound insulation and good noise reduction, and is suitable for thedoors, the windows, the curtain wall glasses and the daylighting roofs of environmentally friendly buildings, ultra-low energy consumption buildings and near zero energy buildings, and other fields.

Description

technical field [0001] The invention relates to the technical field of glass preparation, in particular to a method for manufacturing airgel composite glass. Background technique [0002] Airgel is a lightweight nano-solid material that aggregates nanoscale ultrafine particles to form a nanoporous network structure, and fills the network pores with a gaseous dispersion medium. Its porosity is as high as 99.8%, the typical size of pores is 1-40nm, and the specific surface area is 400-1200m 2 / g, while the density can be as low as 3kg / m 3 , the thermal conductivity at room temperature can be as low as 0.010W / (m•K), showing excellent light weight, light transmission, heat insulation, heat preservation, sound insulation, fire resistance, impact resistance, and excellent chemical stability and non-combustibility. It is precisely because of these characteristics that silica airgel materials have broad application potential in thermal, acoustic, optical, microelectronics, and par...
