摘　　要：稀土金属有机配合物转光剂材料具有吸收阳光中短波段紫外线的功能,并能将吸收的紫外线转化为长波段的蓝紫光和红橙光。织物通过转光剂整理可提高抗紫外、防黄化和老化性能,延长使用寿命。为此,采用固相和液相2种合成方法,合成稀土金属有机配合物防紫外转光剂材料。通过对比固相和液相合成转光剂的红外谱图、水溶液中的分散性能和在纺织面料上的防紫外效果,发现液相合成方法中稀土金属铕离子与有机配体分子结合更充分,液相合成的转光剂材料在水溶液中更易于分散均匀,其提升织物防紫外线效果更加显著。Organic ligands rare-earth light conversion agent can absorb the short wavelength ultraviolet rays in the sunlight, and convert it into long wavelength blue purple light and orange light. Anti-UV finished fabrics with the light conversion agent can improve the fabrics＇ UV-resistant, anti-yellowing, and anti-aging properties, and prolong fabrics＇ service life. This paper discusses two synthesis methods for dual organic ligands rare-earth light conversion agent, one is solid phase synthesis method, and the other is liquid phase synthesis method. By contrast of infrared spectra of the two methods, in respect of dispersion properties in aqueous solution and anti-UV effect, it is found that in liquid phase synthesis, europium ionic binding with organic ligands is more fully, the conversion agent made by liquid phase synthesis is easily solved and dispersed uniformly, and its anti-UV effect is better than that prepared by solid phase synthesis method.
