| 中文摘要: |
| 暴露在太阳光下的物体表面温度较高，影响了其正常的工作状态。在物体表面涂覆反射隔热涂料，因其施工方便、成本较低、隔热性能明显等优点而获得广泛应用。反射隔热涂料中颜料的性能是影响反射隔热涂层隔热性能的关键。然而已经应用的颜料颜色种类单一，反射性能也不够理想，为此需要对其进行表面改性。将常用反射隔热涂层用颜料的改性技术概括为两大类别，即表面包覆改性和离子掺杂改性。对表面包覆改性中的液相沉积法、机械球磨法和单体聚合法进行了介绍和国内外研究现状分析，并指出了适用情形。结合离子掺杂改性中的固相反应法和溶胶凝胶法特点，对各自的优缺点进行了分析和比较，着重介绍了固相反应法和溶胶凝胶法的主要适用情形和近年来国内外研究进展。从颜料的晶体结构出发，阐述了离子掺杂改性增强颜料近红外反射率的机理。最后，结合社会和经济的发展背景，对反射隔热涂层用颜料的改性技术发展趋势作出了展望。 |

| Objects are susceptible to high temperature when being exposed in sunlight, which will affect their working condition. As a widely used heat insulation technology, depositing reflective insulation coatings features in easy construction, low cost and excellent insulation properties. Properties of pigments in reflective thermal insulation coating are key factors determining insulation properties of reflective thermal insulation coating. Pigments already being applied should be modified due to single color and poor reflection properties. Common pigment modification technologies were classified into surface cladding modification and ion doping modification. Liquid deposition, mechanical ball-milling, monomer polymerization in surface cladding modification were introduced, recent research progress at home and abroad was analyzed. What’s more, applicable circumstances were also indicated. Merits and demerits of solid reaction method and sol-gel method in ion doping modification were analyzed and compared by re-ferring to features of both methods. Major applicable circumstances and recent research progress at home and abroad of the two methods were introduced emphatically. Near-infrared reflectance mechanism of ion-doped, modified and enhanced pigments was expounded from crystal structure of pigments. Finally, development trend of modification technology for pigments applied to reflective insulation coating was expected by referring to social and economic development background. |
