Abstract

The invention provides a preparation method for aerogel composite glass. The aerogel composite glass is composed of an aerogel and a glass phase which is used for bonding the aerogel. The preparationmethod comprises the following steps: (1) mixing: uniformly mixing glass powder with the aerogel; (2) melting: heating the glass powder in a mixture obtained in the step (1) to a molten state so as toobtain semi-solid mixed glass melt; (3) calendaring molding: subjecting the mixed glass melt obtained in the step (2) to calendaring molding between rollers or roller plates, and then carrying out cooling; and (4) annealing. The aerogel composite glass disclosed by the invention has good heat insulation performance, light transmittance, safety performance, sound insulation performance and noise reduction performance, and is applicable to the field of doors and windows, curtain wall glass, lighting roofs and the like of green buildings, ultralow-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 preparation method of 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 partic...
