Distribute system with be to hydroxyl benzoic acid and propylene acyl amine, synthesized europium - to hydroxyl benzoic acid - 3 yuan of rare earth cooperate propylene acyl amine content, the hydroxyl of the dissociate in using these 3 yuan of rare earth to cooperate content regards active radical as the group, with 2 butyl laurel is acerbity in Feburary stannum (T-12) is activator, with the toluene that has root of cyanic acid of active radical round different - 2, 2 different of 4- cyanic acid ester (material of glow of polyurethane of high polymer of the bond with TDI) reaction new preparation rare earth. Analyse token through infra-red, hot analysis and fluorescent spectrum the structure of glow material, thermal stability and glow function, the result makes clear, the diagnostic 2270 Cm-1 of root of cyanic acid of the different in TDI absorbs a peak to disappear, the europium that contains hydroxyl cooperates content and monomer of ester of different cyanic acid to react complete; is aroused in 214 Nm wavelengh, cooperate content and glow material to all can give out stronger diagnostic fluorescence in 619 Nm and 592 Nm place, predict in new-style glow coating the respect is having wide applied perspective.
