In order to protect the articles in buildings from ultraviolet radiation and save air-conditioning energy, polyvinyl butyral laminated glass are employed and produced in large quantities. Several inorganic particles with blocking effect have been doped into PVB, such as TiO 2 , ZnO, and ATO. T-ZnOw is a widely used functional structural material with excellent absorption properties. Herein, T-ZnOw was lipophilic modified with silane coupling agent KH-570, and T-ZnOw/PVB composite films were prepared via subsequent solution blending. As per the FTIR spectrum, a characteristic peak of Si–O–Zn at 1165 cm −1 was observed, indicating that T-ZnOw was successfully modified by KH-570. T-ZnOw before and after modification was separately mixed with the St/H 2 O mixed solution. The modified T-ZnOw could be dispersed in styrene instead of water, displaying a certain lipophilicity. On the other hand, from a microscopic perspective, the SEM images suggest that filling the filler in the form of a suspension can disperse the modified T-ZnOw in PVB in an independent four-needle form, which contributes toward improvement of the agglomeration of T-ZnOw in the PVB matrix. The UV–Vis–NIR spectrum shows that the addition of T-ZnOw reduced the UV transmittance of T-ZnOw/PVB composite films from 50.84 to 25.77%, resulting in a decrease in near-infrared transmittance from 82.14 to 43.22%. The ultraviolet and near-infrared light barrier properties of composite films were more than twice that of the ordinary PVB films. Moreover, the modified T-ZnOw endowed composite films with stronger ultraviolet light and near-infrared light-blocking properties, or better visible light transmittance. And the falling ball impact test proved that there was no clear relationship between the thickness of the film and the adhesion. This work proposes a new solution and preparation method for the production of energy-saving glass. Therefore, it is expected that using composite films instead of traditional PVB films to make laminated glass can greatly contribute toward energy conservation and environmental protection.

T-ZnOw的亲油改性及T-ZnOw/PVB复合薄膜的光学性能

为了保护建筑物内的物品免受紫外线辐射和节约空调能源，聚乙烯醇缩丁醛夹层玻璃被大量采用和生产。PVB中掺杂了多种具有阻挡作用的无机颗粒，如TiO 2 、ZnO和ATO。T-ZnOw 是一种应用广泛的功能性结构材料，具有优异的吸收性能。在本文中，T-ZnOw 用硅烷偶联剂 KH-570 进行了亲油改性，并通过随后的溶液共混制备了 T-ZnOw/PVB 复合薄膜。根据 FTIR 光谱，在 1165 cm -1 处观察到 Si-O-Zn 的特征峰，表明 T-ZnOw 被 KH-570 成功改性。改性前后的T-ZnOw分别与St/H 2 O混合溶液混合。改性的 T-ZnOw 可以分散在苯乙烯中而不是水中，显示出一定的亲脂性。另一方面，从微观角度来看，SEM 图像表明以悬浮液形式填充填料可以将改性 T-ZnOw 以独立的四针形式分散在 PVB 中，这有助于改善 T-ZnOw 的团聚。 PVB 基体中的 -ZnOw。UV-Vis-NIR光谱表明，T-ZnOw的加入使T-ZnOw/PVB复合薄膜的紫外透射率从50.84%降低到25.77%，导致近红外透射率从82.14%降低到43.22%。复合薄膜的紫外和近红外光阻隔性能是普通PVB薄膜的两倍以上。此外，改性T-ZnOw赋予复合薄膜更强的紫外光和近红外光阻隔性能，或更好的可见光透射率。落球冲击试验证明膜厚与附着力无明显关系。该工作为节能玻璃的生产提出了一种新的解决方案和制备方法。因此，预计用复合薄膜代替传统的PVB薄膜来制造夹层玻璃，可以为节能环保做出巨大贡献。
