摘　　要：通过添加具有红外阻隔能力的填料,将建筑物内部发射的红外线反射回去,降低能量的损失,从而达到节能的效果。本文使用傅里叶变换红外光谱仪、导热系数仪和智能数字式巡回检测温度测试仪分别测试了添加具有红外阻隔能力填料的内墙涂料的红外吸收光谱、导热系数和温度变化情况,通过测试结果得出结论:水滑石和硫酸镁在质量比为4∶10的时候,红外阻隔性能最优,其温差变化较没有添加水滑石/硫酸镁复合体系时提高5℃左右,而对内墙涂料的导热系数几乎没有影响,这是由于填料对涂料的保温机理不同所致,同时也进一步验证了填料是通过红外阻隔来达到保温效果的。Filles that present strong infrared blocking ability is added into interior wall coatings to reflect the IR within buildings for reduction of energy losses, resulting in heat insulation. FTIR, thermal conductivity device and smart digital rounding temperature testing device are used to test the infrared absorption spectrum, thermal conductivity and temperature changes of the title coatings, It is concluded that when hudrotalcite and magnesium sulfate is mixed by 4 to 10, the heat insulation property is the best, and the temperature changes of Nizi increased by 5℃ approximately compared with those without hydrotalcite and magnesium sulfate compound system, but the heat conduction coefficient is hardly increased because of the different mechanism of heat insulation of the fillers, which further prove that heat insulation with fillers is based on Infrared barrier.
