| 摘 要： | 本文应用DSC、TG和旋转粘度计等研究了一种稀土有机化合物对酸酐固化环氧树脂体系潜伏性促进作用、固化反应动力学参数及其固化物性能的影响,且与通常叔胺促进的酸酐固化环氧树脂体系进行了研究对比.结果表明,这种稀土化合物是酸酐/环氧树脂体系较为理想的潜伏性促进剂.整个固化反应过程遵循准一级动力学方程.以该稀土化合物作促进剂的酸酐/环氧树脂固化物比叔胺作促进剂的酸酐/环氧树脂固化物具有更优异的机电热性能.

| Abstract: | The latent curing acceleration of the rare-earth organometallic compound (MrAn) for the anhydride/epoxy resin system was studied by DSC,TG and rotation viscometer,etc,and commparisons were made with the curing efficiency of terriary amine (DMP 30) in this paper.The results showed that the rare-earth compound served,an ideal latent accelerator for anhydride/epoxy resin systems,the overall curing process followed quasi-first order kinetics,and all total properties of the MrAn catalyzed/anhydride/epoxy resin system were better than those of a DMP-30 catalyzed one. |
