【摘要】：節(jié)能玻璃已在建筑等領域得到越來越廣泛的關注。目前,市場上的節(jié)能玻璃主要為鍍膜玻璃,存在工藝復雜和成本高等問題,而玻璃貼膜材料大多采用有機相的透明涂料與納米材料或有機顏料涂覆所制,存在環(huán)保等問題,因此采用水相涂料制備的綠色節(jié)能貼膜是建筑用節(jié)能玻璃的主要發(fā)展方向。論文采用水熱法制備透明氧化錫銻(ATO)納米水相分散體,并將其與水性樹脂通過簡單的共混方法,制備透明ATO納米復合貼膜材料。研究制備工藝條件對ATO納米顆粒形貌及其在水相中分散性能的影響,以及分散體和納米復合貼膜材料的光學性能。主要研究結果如下：采用水熱法制備了透明ATO納米分散體,考察了摻雜比、pH值、改性劑用量、改性溫度、水熱溫度和水熱時間對ATO納米顆粒形貌、分散性能和光學性能的影響。研究結果表明：錫銻的摩爾摻雜比約為15 m01%,pH值為8,改性劑用量為1.2 wt%,改性溫度為25℃,水熱溫度為240 ℃,水熱時間為16 h的條件下制備得到的ATO納米顆粒粒徑較小,為6-10 nm,粒度分布均勻、在水相中分散性好；ATO納米分散體在550 nm處的可見光透過率為80%,在1250 nm處的紅外線阻隔率為84%。將納米ATO水相分散體和水性樹脂通過簡單的共混方法,制備得到了具有紅外線阻隔作用的透明納米復合貼膜材料。研究了水性樹脂、ATO含量、涂層厚度對透明復合貼膜材料光學性能的影響。研究結果表明：當ATO與聚氨酯質(zhì)量比為3：10,涂層厚度為4μm時制備得到的納米復合貼膜材料表面平整度好,涂層與PET基底間的附著力較強：納米復合貼膜材料在550 nm處可見光的透過率為80%,在1500 nm處紅外線的阻隔率為92%。測試表明該貼膜材料具有顯著的隔熱效果。
[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，
