Method for preparing novel aqueous fluorescence polyurethane

The invention provides a method for preparing novel aqueous fluorescence polyurethane. The method comprises the following step: enabling a fluorescent agent to react with isophorone diisocyanate, polytetramethylene ether glycol and methyldiethanolamine, so as to synthesize a modified aqueous polyurethane fluorescence material. The prepared novel aqueous fluorescence polyurethane has the advantagesof being friendly to environment, high in stability and good in fluorescence effect, and can be applied to fields such as anti-fake marks, traffic marks, elastic materials, chemical detection, fluorescence inks and fluorescence coatings. 本发明提供了一种新型水性荧光聚氨酯的制备方法，通过荧光剂与异佛尔酮二异氰酸酯，聚四亚甲基醚二醇和甲基二乙醇胺反应，合成和改性水性聚氨酯基荧光材料，制备的新型水性荧光聚氨酯具有环境友好，稳定性高，荧光效应强的优点，可以应用于防伪标识，交通标志，弹性材料，化学检测，荧光油墨，荧光涂料等领域。
