Abstract

The invention provides an aerogel composite material preparation method, wherein the aerogel composite material comprises an aerogel and a resin phase adhered to the aerogel. The preparation method comprises: (1) mixing materials, wherein an aerogel and a liquid resin are uniformly mixed; (2) spreading the material, wherein a layer of the mixed melting material obtained in the step (1) is spread on a mold base plate, and curing is performed; and (3) repeatedly spreading the material, wherein the step (2) is repeatedly performed on the previous deposited layer. According to the present invention, the prepared aerogel composite material has advantages of good heat insulation performance, good light transmittance, good safety, good sound insulation and good noise reduction, and is suitable for the doors, 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 preparation of composite materials, in particular to a preparation method of airgel composite materials. 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, microel...
