新型建筑节能镀膜玻璃研究进展

Research progress of new coated glass in energy-saving buildings

“双碳”目标对绿色建筑和节能玻璃提出了更高的要求.我国是浮法玻璃制造大国,平板玻璃年产量占全球总产量的60%以上.普通浮法玻璃不导电、不节能,通过玻璃门窗散失的热量约占整个建筑物散热量的50%.玻璃表面改性是实现玻璃功能化的有效途径,通过镀膜赋予普通浮法玻璃节能功能,对减少碳排放和能源发展战略的实施至关重要.本文围绕课题组在建筑节能镀膜玻璃基础理论、关键技术和工程化应用研究中取得的主要研究成果,系统总结了近年来低辐射镀膜玻璃、阳光控制镀膜玻璃和电致变色智能玻璃的研究进展.低成本、大面积、高效稳定制备技术是建筑节能镀膜玻璃的发展需求,智能化、定制化、系统化是建筑节能镀膜玻璃未来发展趋势.

The aim of the“double carbon”policy puts forward stringent requirements for green buildings and energy-saving glass.China is a large manufacturer of glass,producing>60%of the world’s glass annually.However,ordinary float glass does not conduct electricity and is not energy efficient.Nearly 50%of the heat dispersion in a building occurs through doors and windows.The modification of the glass surface is an effective way to realize glass functionalization.Endowing ordinary float glass with an energy-saving function through coating is important for reducing carbon emissions and implementing energy development strategies.Herein,the research progress of low-emissivity coated,sun-controlled coated,and electrochromic smart glasses in recent years is systematically summarized based on our results related to the basic theory,key technology,and engineering application of coated glass in energysaving buildings.A low-cost,large-area,and high-stability preparation technology is required for energy-saving coated glass,and intellectualization,customization,and systematization are expected to be the future development trends for these glasses.
