摘要： 为了获得较高的热反射性能，大多数热反射隔热涂料为白色或浅色。单调的颜色很难满足现代建筑对不同色彩的需求。文章研究了彩色热反射涂料制备过程中原材料对性能的影响。通过 试发现，添加冷颜料的彩色热反射涂料与普通外墙涂料相比，除了具备同样的色彩装饰效果，更重要的是具有优异的热反射性能，能有效节省能源。实验中，普通深灰外墙涂料的太阳光反射比为 0.092，而相同颜色的热反射涂料太阳光反射比为 0.297，两者 1h、1.5h隔热温差达到 8.5°C和 8.7°C。

Abstract:

Most of solar reflective thermal insulation coatings have white or light color to provide higher heat reflective performance But white or light color is difficult to meet the demand of modern decoration. This article has discussed the influence of raw materials on the performance of color solar reflective thermal insulation coatings. Color solar reflective thermal insulation coatings with cool pigments could give excellent heat reflection properties, the same decorative effect as that of the normal exterior wall paints, showing effective energy saving advantage. In this experiment,

the total reflectance of ordinary dark gray exterior paint was 0. 092, while the total reflectance of solar reflective thermal insulation coatings with the same color was 0.297. The thermal insulation temperature difference between them after 1 h and 1.5h could be 8.5 ℃ and 8.7 ℃.
