摘　　要：利用稀土长余辉发光材料的吸光-发光特性,将其应用到道路涂料中以解决夜间、无照明条件下道路标线难以被识别的问题。采用能谱仪、X射线衍射仪、荧光分光光度计分别对2种荧光粉的元素构成与有效含量、矿物组成、荧光性能进行了表征。结果表明:2种荧光粉主要成分均为单斜相SrAl2O4,其中荧光粉B中含有较多的碳元素杂质,受其影响,荧光粉B发光需要较高强度的激发能,发光强度弱于荧光粉A;将2种荧光粉按照5种比例分别与环氧树脂混合,配制出10种荧光涂层,采用长余辉荧光粉测试仪对荧光涂层的发光性能进行表征,获得荧光涂层的最佳工艺:涂层厚度为1.8mm,荧光粉A与环氧树脂的质量比为5∶5,粘结强度为0.54MPa。Based on the light absorption and emission properties of long-lasting phosphor materials,it is often mixed in road coatings to solve the problem that road markings are difficult to be identified at night and without lighting conditions.The elemental compositions,effective contents,mineral compositions and fluorescence properties of the two phosphors were characterized by means of spectrometer,X-ray diffractometer and fluorescence spectrophotometer respectively.Results showed that the main components of both phosphors were monoclinic SrAl2O4,but the Phosphor B contained more carbon impurities.Due to its influence,Phosphor B luminescence required higher excitation energy,and the luminescence intensity was also weaker than that of Phosphor A.10 fluorescent coatings were prepared by mixing the two phosphors with epoxy resins at 5 ratios,and the luminescent properties of the fluorescent coatings were characterized by a long afterglow phosphor tester.The best technology for the fluorescent coatings was 1.8 mm thick,and the quality ratio of fluorescent powder A to epoxy resin was 5:5.The adhesive strength of fluorescent coating was 0.54 MPa under the best technology.
