| 目的 针对目前广泛应用的传统型保温隔热建筑材料存在的施工困难、体系过厚、装饰性安全性较差等不足，制备力学性能和装饰性优异的隔热节能涂层。方法 使用KH560对硅溶胶进行改性，与苯丙乳液进行复合制备隔热节能涂料的成膜基料，加入质量分数分别为5%、10%、15%、20%的群青、钴蓝颜浆，制备8种隔热节能涂层。采用傅里叶红外变换光谱仪、马尔文Zeta电位仪、扫描电镜和热重分析仪分别对硅溶胶的接枝改性效果、粒径分布、微观形貌及热稳定性进行测试。采用扫描电镜、X射线衍射仪、电子探针分别对2种颜料的微观形貌、晶体特性和元素组成进行分析。采用紫外/可见/近红外分光光度计测试2种蓝色颜料和节能涂层的太阳光反射比和近红外反射比。采用红外热像仪对涂层试板隔热性能进行测试。采用多种涂层力学测试工具和扫描电镜分别对涂层的综合力学性能、微观形貌进行表征。结果 KH560对无机硅溶胶改性效果较好，可以显著降低硅溶胶的团聚，提升硅溶胶的热稳定性及其在有机乳液的分散性。群青和钴蓝颜料的添加量为5%时，2种涂层的节能隔热效果达到最优。添加量为5%群青的涂层的太阳光反射比、近红外反射比分别为0.462、0.533，添加量为5%钴蓝的涂层的太阳光反射比、近红外反射比分别为0.311、0.522。红外热像图显示，添加量为5%群青的涂层和5%钴蓝的涂层的背面热平衡温度分别为68.0、65.5 ℃，较空白板分别降低了4.9、7.4 ℃。颜料的添加量5%时，2种涂层均具有优异的力学性能，经盐溶液浸泡30 d后2种涂层均无明显微观和宏观缺陷，能满足实际使用需要。结论 隔热反射性能测试结果表明，制备的反射型隔热节能涂层的隔热性能较优异，同时兼具较好的力学性能和耐腐蚀性能，符合当下绿色环保的发展理念。 |

| The work aims to prepare a thermal insulation and energy-saving coating with excellent mechanical properties and decoration in view of the shortcomings of the widely used traditional thermal insulation building materials, such as difficulty in construction, too thick system and poor decorative safety. The silica sol was modified by KH560 and compounded with styrene matrix emulsion to prepare the base film forming material for thermal insulation and energy-saving coatings. Ultramarine blue and cobalt blue pigments of 5%, 10%, 15% and 20% were added respectively to prepare 8 kinds of thermal insulation and energy-saving coatings. The grafting modification effect, size distribution, micro morphology and thermal stability of silica sol were tested by Fourier transform infrared spectrometer, Malvin Zeta potentiometer, scanning electron microscope and thermogravimetric analyzer. The micro morphology, crystal properties and element composition of the two pigments were analyzed by scanning electron microscope, X-ray diffraction and electron probe microanalysis. The solar reflectance and near-infrared reflectance of two blue pigments and energy-saving coatings were measured by UV/VIS/NIR spectrophotometer. The thermal insulation performance of coated test panels was tested by infrared thermal imager. The comprehensive mechanical properties and micro morphology of the coating were characterized by a variety of coating mechanical test tools and scanning electron microscope. KH560 had good modification effect on inorganic silica sol, which could significantly reduce the agglomeration of silica sol and enhance the thermal stability of silica sol and its dispersion in organic emulsion. When the amount of ultramarine blue and cobalt blue pigments was 5%, the energy-saving and thermal insulation effect of the 2 coatings was the best. The solar reflectance and near infrared reflectance of 5% ultramarine blue coating were 0.462 and 0.533 respectively, and that of 5% cobalt blue coating was 0.311 and 0.522 respectively. The infrared thermogram showed that the back heat balance temperature of 5% ultramarine blue coating and 5% cobalt blue coating were 68.0 ℃ and 65.5 ℃ respectively, which were 4.9 ℃ and 7.4 ℃ lower than those of empty board. When 5% pigment was added, the 2 coatings had excellent mechanical properties. After soaking in salt solution for 30 days, the two coatings had no obvious micro and macro defects, which could meet the needs of practical use. The test of thermal insulation and reflection performance shows that the prepared reflective thermal insulation and energy-saving coating has excellent thermal insulation performance, good mechanical properties and corrosion resistance, which is in line with the development concept of green environmental protection. |
