摘要/Abstract

摘要： 通过Pickering聚合法，制备了以固态石蜡为芯材、高太阳反射比TiO₂与聚甲基丙烯酸甲酯（PMMA）为壳层的新型双层包覆智能控温相变微胶囊（PCM@TiO₂）；采用饱和氢氧化钙溶液前处理空心玻璃微珠（HGM），以非均相沉淀法成功合成了纳米二氧化钛颗粒包覆空心玻璃微珠（HGM@TiO₂）。通过扫描电子显微镜（SEM）、X-ray衍射仪（XRD）、能量色散光谱仪（EDS）、低温差示扫描量热（DSC）和紫外-可见-近红外分光光度计（UV-Vis-NIR）对样品形貌、结构、成分进行分析，并将新型隔热填料PCM@TiO₂、HGM@TiO₂以及纳米TiO₂添加到硅丙乳液中制成反射隔热水性涂料，测试其涂层的隔热温差。结果表明：固定隔热填料的总质量为10g，当PCM@TiO₂用量为4g时，太阳反射比为85.61%，隔热温差为12.7℃；当HGM@TiO₂用量为6g时，太阳反射比为80.27%，隔热温差为14.1℃。

Abstract: A novel double-coated phase change microcapsule(PCM@TiO₂) with solid paraffin as core and TiO₂/poly(methyl metha-crylate)(PMMA) as shell was prepared by pickering polymerization. TiO₂-coated hollow glass microspheres(HGM@TiO₂) was successfully prepared by heterogeneous precipitation method after hollow glass microspheres(HGM)pretreated with saturated Ca(OH)₂ solution. The structure and property of the materials were analyzed using scanning electron microscopy(SEM),energy dispersive spectroscopy(EDS),low-temperature differential scanning calorimetry(DSC),X-ray diffraction(XRD),and UV-Vis-NIR spectroscopy. To prepare water-based reflective insulating paints,PCM@TiO₂ or HGM@TiO₂ was added to silicone-acrylic emulsion,and thermal insulation temperature difference was measured. The results showed that with the fixed amount of insulating filler of 10g,the solar reflectance was 85.61% and temperature difference was 12.7℃ when the amount of PCM@TiO₂ was 4g,and the solar reflectance was 80.27% and temperature difference was 14.1℃ when the dosage of HGM@TiO₂ was 6g.

Key words: phase change microcapsules, titanium dioxide coated, hollow glass microspheres, solar reflectance, thermal insulation temperature difference
