【 摘 要 】

Based on the existing preparation process of common thermal insulation coatings, a kind of high reflectance color solar heat-reflective insulation coatings was developed by improving the thermal insulation coatings. The effects of hollow glass beads, titanium dioxide and other factors on the properties of the coatings were discussed, and the thermal insulation properties of the coatings were characterized by solar reflectance ratio. The results show that the water-based color solar heat-reflective insulation coatings with high solar reflectance, high weathering resistance and high stain resistance can be prepared by using pure acrylic emulsion and silicone acrylic emulsion as the film-forming base material, using the rutile type titanium dioxide, calcined kaolin, precipitated barium sulphate and hollow glass beads as the insulated function pigments and fillers, and using the auxiliaries for coatings.
