摘要
Abstract
To reduce energy consumption of buildings, dark blue building energy saving coatings were prepared by using flake cobalt blue as pigment and modified silica sol-styrene acrylic emulsion as adhesive. The influence of the cobalt blue on the properties of the coatings were then tested and characterized by using XRD diffraction, ultraviolet/visible/near infrared spectrophotometry, infrared emissivity measurement, and precision chromatic meter techniques. A custom-made infrared lamp to simulate sunlight heating was used to analyze the properties of heat insulation. The results demonstrate that the average near infrared reflectance of cobalt blue is 49.64% and the average near infrared reflectance of the coatings is 21.47% when the content of cobalt blue is 15%. Meanwhile, the normal infrared emissivity of the coatings in the 8-14μm wave band is as high as 0.96. The equilibrium temperature of the reverse side of the plate coating is 7.5℃ lower than that of blank asbestos cement. Thus, the effective heat resistance obtained with this coating is impressive.关键词
