Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a novel heat-insulating coating for buildings. Background technique [0002] Thermal insulation coating is a kind of coating applied on the surface of buildings, which can effectively reduce the temperature of the surface and interior of buildings. In recent years, with the popularization of building energy saving, thermal insulation coatings have attracted more and more attention because of their advantages of economy, convenience and good thermal insulation effect. Thermal insulation coatings can generally be divided into three categories: barrier thermal insulation coatings, reflective thermal insulation coatings and radiation thermal insulation coatings according to the different thermal insulation mechanisms and methods. Among them, the reflective heat insulation coating generally adopts the design concept of "sparse", which reflects the energy of sunlight ...
