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) spreading an aerogel layer, wherein a layer of an aerogel is spread on a mold base plate; (2) filling with a liquid resin, wherein the aerogel layer obtained in the step (1) is filled with a liquid resin in a stepped scanning manner by using a material distribution device having heating function; (3) repeatedly performing the step (1) and the step (2) on the previous deposited layer,and alternately distributing the materials; and (4) curing. 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 aerogel composite materials. Background technique [0002] Aerogel is a kind of lightweight nano-solid material in which nano-scale ultrafine particles aggregate with each other to form a nano-porous network structure, and the network pores are filled with 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 , room temperature thermal conductivity can be as low as 0.010W / (m•K) or less, 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 aerogel materials have broad application potential in...
