【摘要】：节能玻璃已在建筑等领域得到越来越广泛的关注。目前,市场上的节能玻璃主要为镀膜玻璃,存在工艺复杂和成本高等问题,而玻璃贴膜材料大多采用有机相的透明涂料与纳米材料或有机颜料涂覆所制,存在环保等问题,因此采用水相涂料制备的绿色节能贴膜是建筑用节能玻璃的主要发展方向。论文采用水热法制备透明氧化锡锑(ATO)纳米水相分散体,并将其与水性树脂通过简单的共混方法,制备透明ATO纳米复合贴膜材料。研究制备工艺条件对ATO纳米颗粒形貌及其在水相中分散性能的影响,以及分散体和纳米复合贴膜材料的光学性能。主要研究结果如下：采用水热法制备了透明ATO纳米分散体,考察了掺杂比、pH值、改性剂用量、改性温度、水热温度和水热时间对ATO纳米颗粒形貌、分散性能和光学性能的影响。研究结果表明：锡锑的摩尔掺杂比约为15 m01%,pH值为8,改性剂用量为1.2 wt%,改性温度为25℃,水热温度为240 ℃,水热时间为16 h的条件下制备得到的ATO纳米颗粒粒径较小,为6-10 nm,粒度分布均匀、在水相中分散性好；ATO纳米分散体在550 nm处的可见光透过率为80%,在1250 nm处的红外线阻隔率为84%。将纳米ATO水相分散体和水性树脂通过简单的共混方法,制备得到了具有红外线阻隔作用的透明纳米复合贴膜材料。研究了水性树脂、ATO含量、涂层厚度对透明复合贴膜材料光学性能的影响。研究结果表明：当ATO与聚氨酯质量比为3：10,涂层厚度为4μm时制备得到的纳米复合贴膜材料表面平整度好,涂层与PET基底间的附着力较强：纳米复合贴膜材料在550 nm处可见光的透过率为80%,在1500 nm处红外线的阻隔率为92%。测试表明该贴膜材料具有显著的隔热效果。
[Abstract]:Energy-saving glass has been paid more and more attention in construction and other fields. At present, the main energy-saving glass in the market is coated glass, which has many problems such as complicated process and high cost. However, most of the glass coating materials are made of transparent coating of organic phase and nano-materials or organic pigments, and there are some problems such as environmental protection. Therefore, the green energy-saving film prepared by water-phase coating is the main development direction of building energy-saving glass. In this paper, transparent tin antimony oxide (ATO) nano-aqueous dispersion was prepared by hydrothermal method, and transparent ATO nanocomposite film was prepared by a simple blending method. The effects of preparation conditions on the morphology of ATO nanoparticles and their dispersion in aqueous phase, as well as the optical properties of dispersions and nano-composite films were studied. The main results are as follows: transparent ATO nanoparticles were prepared by hydrothermal method. The effects of doping ratio pH value, modifier dosage, modification temperature, hydrothermal temperature and hydrothermal time on the morphology, dispersion and optical properties of ATO nanoparticles were investigated. The results show that the molar ratio of tin to antimony is about 15m01g, the pH value is 8, the modifier dosage is 1.2 wt%, the modification temperature is 25 鈩，
