【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。更多还原

【Abstract】 Nanometer material as an emerging discipline, architectural glass nano thermal insulationcoating preparation synthesis is the hotspot in the nanometer materials application of buildingenergy efficiency. Through a variety of domestic and foreign journals, patents, papers,documents and other information, it can be found that some of the architectural glass heatinsulation paint preparation contents and methods of synthesis.However, based on the existing domestic and foreign existing literature on building glassthermal insulation coatings, disclosed patent, report, academic papers and other data collation,as well as the development of sci-tech novelty retrieval, and the coating of insulating glassconstruction engineering investigation, combined with the building heat insulation coatingglass engineering experience, the current architectural glass heat insulation paint have fourmain problems:(1) Slurry dispersion mode is single, dispersion stability is poor;(2) Thetransmission of visible light and infrared thermal barrier effect index care for this and lose that,photo thermal technique index, physical performance, safety and environmental protection isdifficult taking into account at the same time. Lacking of the comprehensive data in thermalbalance index (visible light transmittance and shading coefficient ratio);(3) the research ofAnti-aging and anti-UV performance is deficient and short;(4) A few researches are on thespecific heat insulation effect and quantitative indicators, but it lacks of thermal parametersetting clear and comprehensive thermal experiments, specific thermal parameters andparameter range of coating insulating glass.In view of the above problems, the experiment explores and synthesis to meet the needfor energy saving, appropriate technology, with the core technology of high performance ATOalcohol formulation of nano building glass thermal insulation coatings, solves some problemsof nanometer thermal insulation coating of architectural glass:(1) Based on the existingcommon physical dispersing method, it proposed the feasible phase dispersing manner toimprove the stability of ATO. The sedimentation rate of phase dispersion mode optimization isin decline, slurry stability can be maintained longer;(2) Based on study of ATO solid contentand thermal properties, physical properties of the coated glass, the hardness is enhanced withexisting alcohol coating glass film hardness in the same thermal index;(3) By adding the short wavelength light eliminating liquid and the amount of alcohol stabilizer, coating glassanti-aging performance improved significantly;(4) Building experimental platform withcomprehensive and systematic thermal parameters, it measured experiment cabinets airtemperature, and calculated the engineering significance of coating insulation glass insulationtemperature range as well as coating glass heat transfer coefficient K value range.Based on the architectural glass nano thermal insulation coatings research anddevelopment as well as coating glass thermal performance, the experiment effectivelyimprove the performance of the existing building glass nano thermal insulation coatings,thermal properties and thermal parameters to quantify the building coating glass, providinggreen building materials of high performance for the development of building energyconservation.
