【摘要】：纳米材料作为新兴学科，建筑玻璃纳米隔热涂料的制备合成是目前纳米材料在建筑节能应用上的热点。通过对目前国内外各种期刊、专利、学术论文、文献等资料的查阅，可以发现一些关于建筑玻璃隔热涂料制备合成的研究内容及研究方法。然而通过对国内外现有关于建筑玻璃纳米隔热涂料的文献、已公开专利、报告、学术论文等资料的整理，以及科技查新工作的开展，并对涂膜隔热玻璃建筑工程进行的实地考察，结合涂膜隔热玻璃建筑工程实践经验的总结发现，目前建筑玻璃隔热涂料主要存在以下四个方面的突出问题:（1）浆料分散方式较为单一，分散稳定性较差；（2）可见光透过与红外阻隔光热指标顾此失彼，光热性能、物理性能和安全环保性难以同时兼顾，缺乏光热平衡指标（可见光透过率与遮阳系数比值）下的综合数据；（3）抗老化及抗紫外性能研究较少且抗老化时间短；（4）建筑玻璃隔热涂料的具体隔热效果及量化指标方面的研究较少，缺乏热工参数设定清晰而全面的热工实验，欠缺涂膜隔热玻璃具体的热工参数及参数范围。针对以上问题，论文探索并制备合成了满足节能改造需要，技术适宜，具有核心技术配方的高性能ATO醇性纳米建筑玻璃隔热涂料，较好的解决了建筑玻璃纳米隔热涂料中存在的一些问题:（1）在现有常见物理分散方式的基础之上，提出了提高ATO稳定性较为可行的阶段化分散方式，进一步降低了浆料的沉降率，延长了保存时间；（2）在ATO固含量与涂膜玻璃光热性能、物理性能的研究基础之上，制得的涂膜隔热玻璃在同样光热指标下，，较目前现有醇性涂膜玻璃的膜层硬度有了一定程度的提升；（3）通过添加短波波段光线消除液和适量的醇类稳定剂等助剂，大幅度提升了涂膜玻璃的抗老化性能；（4）搭建热工参数全面而系统的实验平台，测试实验箱体内空气温度，计算出了具有工程意义的涂膜隔热玻璃的隔热温差范围和涂膜玻璃传热系数K值范围。本文围绕建筑玻璃隔热涂料研发以及涂膜隔热玻璃热工性能所开展的工作，有效的提升了现有建筑玻璃隔热涂料的性能，量化了建筑涂膜隔热玻璃的热工性能及热工参数，为建筑节能的发展提供了高性能的绿色建材，论文及其结论具有理论价值和应用价值。
[Abstract]:Nanomaterials as a new subject, the preparation and synthesis of architectural glass nano-thermal insulation coatings is a hot spot in the application of nano-materials in building energy conservation. Through the domestic and foreign various journals, patents, academic papers. By consulting the literature, we can find some research contents and research methods on the preparation and synthesis of building glass insulating coatings. However, through the existing domestic and international literature on architectural glass nano-thermal insulation coatings, has been published patents, reports, academic papers and other materials, as well as the development of scientific and technological novelty. And the field investigation of the coated insulating glass construction project, combined with the practical experience of the coated insulating glass construction project summary and discovery. At present, there are four main outstanding problems in the building glass insulation coatings: the slurry dispersion mode is relatively single, and the dispersion stability is poor; (2) visible light transmission and infrared barrier photothermal index, the photothermal performance, physical performance and safety and environmental protection are difficult to take into account at the same time. Lack of comprehensive data under the light and heat balance index (ratio of visible light transmittance to shading coefficient); (3) the anti-aging and anti-ultraviolet properties are less studied and the anti-aging time is short. 4) the specific thermal insulation effect and quantitative index of building glass insulation coatings are less studied, and lack of clear and comprehensive thermal experiment of setting thermal parameters. Lack of coating thermal insulation glass specific thermal parameters and parameters range. Aiming at the above problems, the paper explored and prepared the high performance ATO alcohol nano-building glass insulation coatings which meet the needs of energy-saving transformation, suitable technology and have the core technology formula. On the basis of the common physical dispersion methods, a feasible method of improving the stability of ATO was put forward. The sedimentation rate of the slurry is further reduced and the preservation time is prolonged. 2) on the basis of the study of ATO solid content and the photothermal and physical properties of the coated glass, the coated heat-insulating glass is prepared under the same photothermal index. Compared with the existing alcohol-coated glass film hardness has a certain degree of improvement; The anti-aging property of the coated glass was greatly improved by adding some additives such as short-wave band ray elimination solution and proper amount of alcohol stabilizer. Build a comprehensive and systematic experimental platform of thermal parameters to test the air temperature in the experimental box. The range of thermal insulation temperature difference and the K value range of heat transfer coefficient of coated glass are calculated. This paper focuses on the research and development of building glass thermal insulation coatings and thermal properties of coated glass insulation, effectively improve the performance of existing building glass thermal insulation coatings. The thermal properties and thermal parameters of the coated insulating glass are quantified, which provides high performance green building materials for the development of building energy saving. The paper and its conclusions have theoretical value and application value.
