| 目的 提高建筑节能涂层的隔热性能，为多种隔热机理于一体的建筑节能涂层提供借鉴意义。方法 自制复合乳液作为复合涂层的粘合剂，将含空心微珠填料的涂层做底面涂层，含镍钛黄颜料的涂层做表面涂层，制备了底-表面复合型建筑节能涂层，并探究了镍钛黄掺量对涂层性能的影响。采用X射线衍射仪、紫外/可见光/近红外分光光度计、长波发射率仪、精密色差仪和扫描电子显微镜对镍钛黄和涂层性能进行表征，采用红外灯模拟太阳热源测量涂层的隔热性能。结果 镍钛黄晶体结构为金红石型，且具有优异的可见光和近红外反射特性，其在可见光和近红外波段的平均反射率达72.61%。镍钛黄掺量对复合涂层在可见光和近红外波段平均反射率具有一定的影响，当镍钛黄掺量为20%时，复合涂层在近红外波段的平均反射率最高为66.75%，此时涂层在3~5 μm和8~14 μm波段的长波发射率分别为0.95和0.94，试板背面平衡温度比仅含相同掺量镍钛黄的表面涂层试板背面平衡温度降低2.4%，隔热性能得到提升。结论 采用阻隔-反射型/底-表面复合结构可以提升建筑节能涂层的隔热性能，实际应用时颜料掺量以20%为宜。 |

| The work aims to improve insulation performance of building energy-saving coatings and providing certain reference significance for building energy saving coatings featuring in multiple thermal insulation mechanisms. Undersurface/surface composite building energy-saving coatings were prepared with hollow glass micro-bead as undersurface coatings, coatings containing nickel titanium yellow as surface coatings and self-made composite emulsion as adhesive. What’s more, effects of content of nickel titanium yellow on properties of coatings were investigated. Properties of nickel titanium yellow and coatings were characterized using XRD, ultraviolet/visible/near-infrared spectrophotometer, infrared emissivity measurement device, precise colorimeter and scanning electron microscope. Infrared lamp was used to simulate sunlight heat source and analyze insulation performance of the coatings. Rutile nickel titanium yellow was a rutile-type structure exhibiting excellent reflective characteristic in visible light and near-infrared light, its average reflectance in visible light and near-infrared band was 72.61%. The average reflectance of coatings in visible light and near-infrared band was influenced by content of nickel titanium yellow to a certain extent. Provided that nickel titanium yellow was 20%, near infrared average reflectance of the composite coatings could be up to 66.75%. Meanwhile, long wave emissivity of coatings in wave band of 3~5 μm and 8~14 μm was 0.95 and 0.94, respectively. Equilibrium temperature on reverse side of the composite coatings was 2.4% lower than that of surface coatings with the same content of nickel titanium yellow. Thus, insulation performance of building energy-saving coatings can be improved by using barrier-reflection type/subface-surface composite structure, optimum content of the pigment shall be 20% in practical application. |
