摘要
有机脲类化合物一般作为一种有效固化促进剂使用。但作者经大量的实验得出,有机脲类可以单独作为一种优良的快速固化剂,其固化速度快,并且有优良的附着性能。研究结果表明,有机脲类化合物ND作为快速潜伏性环氧树脂固化剂,在环氧粉末涂料中加入4%时,固化温度为180℃,粉料55秒可以完全固化。
The organic urea compound is used as a kind of effective accelerator, but now a conclusion is put forward that the organic urea compound is independently used as a sort of rapid and excellent solidified agent, which solidifies rapidly and has outstanding performance of adherence. ND, which is a rapid latent epoxide resin, solidified agent and accelerator, is a kind of organic urea compound. When 4 wt% ND is added to epoxy powder coating, it can be solidified in 55 sec.
