摘要

对9种浅色涂料的紫外可见光近红外波段反射光谱以及表面温度进行测试

探究颜色对太阳辐射吸收特性的影响机理

明确涂料表面温度与太阳辐射吸收特性的关联。结果表明

9种涂料太阳辐射吸收系数的最高值和最低值相差0.1539;色相对可见光波段的反射光谱曲线波形以及近红外波段的反射比大小影响显著

色相值越大

反射光谱曲线波谷位置向低波长偏移

即对短波段辐射能具有更强的吸收效果;饱和度影响可见光波段光谱曲线波动幅度

高饱和度涂料对波峰处辐射能具有更强的反射能力

对波谷处辐射能具有更强的吸收能力。此外

太阳辐射吸收系数越大

涂料表面温度越高

且可见光波段光谱波长特征亦影响涂料的太阳辐射吸收效果

当涂料的低反射率波带更宽、高反射率波段太阳辐射密度更低时

涂料表面温度更高。

Abstract

The reflection spectra in the ultraviolet

visible and near-infrared bands and the surface temperatures of nine light-colored coatings were tested to explore the influence mechanism of color on the absorption characteristics of solar radiation and clarify the correlation between the absorption characteristics and surface temperature of the coatings. The results show that the difference between the maximum and minimum values of the solar absorption coefficients of the nine coatings is 0.1539. Hue has a significant impact on the waveform of the reflection spectrum curve in the visible band and the reflectance in the near-infrared band. The larger the hue value

the trough of the reflection spectrum curve shifts towards the low wavelength

indicating a stronger absorption on short-waveband radiant energy. Saturation affects the fluctuation amplitude of the spectral curve in the visible band. Coatings with high saturation have a stronger reflection property for radiant energy at the peak and a stronger absorption property for radiant energy at the trough. In addition

the larger the solar radiation absorption coefficient

the higher the surface temperature of the coating. Also

the spectral wavelength characteristics in the visible light band affect the solar radiation absorption of the coating. When the low-reflectivity band of the coating is wider and the solar radiation density in the high-reflectivity band is lower

the surface temperature of the coating is higher.
