| 摘 要： | 以六亚甲基二异氰酸酯三聚体、丙烯酸羟乙酯及羟基含氟丙烯酸酯为原料制备了电子束固化含氟聚氨酯丙烯酸酯预聚物. 通过傅里叶变换红外光谱(FTIR)和核磁共振氢谱(1H NMR)对产物进行了表征. 研究了产物与溶剂组成的两相混合体系的流变性能、电子束固化行为及固化后涂层性能. 结果表明, 产物与溶剂混合体系具有正触变性, 绝对黏度变化符合Sedden公式, 黏流活化能约为44.8 kJ/mol. 电子束固化后涂层性能(如热稳定性、硬度、附着力和光泽度)优良.

| Abstract: | The fluorine-containing electron beam curing polyurethane acrylate was prepared by hexamethy-lene diisocyanate triplolymer,hydroxyethyl acrylate and hydroxyl fluorine-containing acrylate.The expected products were proved by FTIR and 1H NMR.The rheological properties of the two-phase mixed system of the product and solvent,electron beam curing behavior and the properties of the cured coating were studied.The results show that the thixotropy of the mixed system has positive thixotropy,the absolute viscosity follows Sedden formula,and the viscous flow activation energy is about 44.8 kJ/mol.Electron beam cured coating has fine thermal stability,hardness,adhesion and glossiness. |
