建筑外饰面材料光反射特性实验研究

摘要

Different kinds of architectural external decorative materials with different light reflection character⁃istics present different color effects, so the systematic research on light reflection characteristics of external decorative materials is needed for researching urban architectural color. This article chose 29 pieces of com⁃monly used architectural external decorative materials as experimental samples including different colors of coating, facing brick, aluminum composite panel and marble. The luminance and chrominance reflection characteristics of these materials have been researched under different illumination/observation conditions. The relationship between building facing material luminance and chrominance reflection characteristics with illumination/observation conditions, material type has been discussed. These results could provide science foundation support on architectural color research.%不同种类的建筑外饰面材料具有不同的光反射特性，其所呈现的外观色彩效果是不同的，因此研究城市建筑色彩需要对外饰面材料的光反射特性进行系统研究。文章选择了不同色彩的涂料、面砖、铝塑板和大理石共29块常用的建筑外饰面材料作为实验样品，研究了不同入射／观测角度外饰面材料的亮度和色度反射特性，探讨了建筑外饰面材料的亮度和色度反射特性与入射／观测角度、材质类型的关系，为建筑色彩研究提供科学基础支撑。
