摘　　要：以异佛尔酮二异氰酸酯、聚乙二醇1000、2,2-二羟甲基丁酸(DMBA)、荧光单体盐酸吖啶黄(AH)、季戊四醇三丙烯酸酯(PETA)和中和剂三乙胺(TEA)为原料合成了光固化型荧光聚氨酯染料(UFPD-0~UFPD-3),然后将盐酸吖啶黄掺杂到UFPD-0中混合均匀制备了UFPD+3。并通过丝网印刷和紫外光聚合的方式得到了不同的光固化涂层织物。同时对光固化涂层织物的干燥时间、光照条件进行了研究。结果表明,荧光单体盐酸吖啶黄成功接枝到聚氨酯分子链上,接枝样品具有良好的热稳定性能。UFPD-3的水乳液表现出最大为1 793的相对荧光发射强度,相比之下UFPD+3的水乳液仅仅表现出505的荧光发射强度。干燥时间为20 min、光照强度为100%和光照时间为80 s时得到的织物具有最大的相对荧光发射强度和鲜艳的颜色。以UFPD-3水乳液进行印花后得到的光固化涂层织物的紫外防护系数(UPF值)达到了66.89,色牢度达到了4~5级。A series of UV-curable fluorescent polymer dyes(UFPD-0-UFPD-3)were synthesized from isophorone diisocyanate,polyethylene glycol 1000(PEG1000),2,2-dihydroxymethylbutyric acid(DMBA),fluorescent monomer acridine yellow hydrochloride(AH),pentaerythritol triacrylate(PETA)and neutralizer triethyla mine(TEA),then acridine yellow hydrochloride was doped into UFPD-0 and mixed homogeneously to prepare UFPD+3.Different UV-curable coated fabrics were obtained by screen printing and UV-light polymerization.The drying time and light conditions of UV-curable coated fabrics were also investigated.The results showed that the fluorescent monomer acridine yellow hydrochloride was successfully grafted onto the polyurethane molecular chain and the grafted samples showed good thermal stability.Aqueous emulsion of UFPD-3 exhibited a maximum relative fluorescence emission intensity of 1793,compared with only 505 for UFPD+3.The fabrics obtained with a drying time of 20 min,a light intensity of 100%and a light time of 80 s displayed the highest relative fluorescence emission intensity and bright colors.The UV protection factor(UPF value)of the UV-curable coated fabric obtained after printing with UFPD-3 aqueous emulsion reached 66.89,and the color fastness reached 4-5 grade.
