纳米晶体与蓄光型发光材料复合改性水性聚氨酯木器涂层的物理力学性能研究

Study of Physical and Mechanical Properties of SrAl_2O_4:Eu,Dy/CNC Waterborne Polyurethane Wood Coatings

随着人们环保意识的逐步提高,用于木器清漆涂料的产品标准也越来越严格,安全环保无污染的水性涂料在木器清漆行业的应用逐渐成为趋势。本文主要以水性聚氨酯木器涂料展开研究,采用高强度、高比表面积的纤维素纳米晶体(CNC)和蓄光型发光材料(Sr Al2O4:Eu,Dy)对其进行改性,以求开发出以安全指示为目的的功能型涂层、综合性能更优的水性PU木器涂料,为扩大水性PU木器涂料的产业化应用提供必要的理论依据。

With the gradual improvement of people＇s awareness of environmental protection,the specifications of coatings applied in wood varnish coating products have become increasingly stringent,and the application of environmentally friendly,pollution-free water-based coatings in the wood varnish industry has gradually become a trend. This paper mainly focuses on waterborne polyurethane wood coating research,which was modified by cellulose nanocrystals（CNC）and luminescent materials（SrAl2O4：Eu,Dy）with high specific surface area to develop a functional coating based on safety instructions. A PU wood coating with better comprehensive performance was developed and the research behind it will provide the necessary theoretical basis for expanding the industrial application of waterborne PU wood coating.
