Preparation and performances of SiO2 aerogel heat-insulation coatings

In this paper, the SiO 2 aerogel heat-insulation coatings with high performance-price ratio are prepared by making use of SiO 2 aerogel prepared under the normal temperature and pressure drying process as the functional filler. The effects of such factors as SiO 2 aerogel amount, infrared powder, film thickness and emulsion varieties on coating performance are studied. As shown by the experimental results, SiO 2 aerogel significantly can improve the heat insulation properties of coatings, and can be widely applied in energy-saving of buildings, industrial pipelines and chemical storage tanks.
