Design of thermal insulation energy-saving coatings for exterior wall

Abstract

Thermal insulation coatings can effectively prevent coatings and substrate from solar radiation under the condition of zero-energy consumption, which could improve the working conditions and reduce the energy consumption. A kind of thin layer thermal insulating energy-saving coatings with high performance was designed by synergistic effect of thermal insulation mechanisms during the process of light and heat transfer. The excellent performance of coatings had characterized with low thermal conductivity, good insulation effect, high reflectivity, and so on. Moreover, double insulation system as an optimized thermal insulation coating structural model was proposed and designed. The reflection-insulation type thermal insulation coating was used as the top-coat to form reflection-insulation layer, and the radiation-insulation type thermal insulation coating was used as the intermediate-coat to form radiation-insulation layer. The double system had advantages of good thermal insulation and convenient process, and it is also easy to rush, save energy and reduce energy consumption. Some issues of insulation coatings were explored and explained, such as coating strength, filler arrangement and coating thickness.
