| 摘 要： | 通过在不饱和聚酯树脂中加入活性端基聚氨酯橡胶来降低树脂的体积收缩.树脂固化前,橡胶与不饱和聚酯树脂相溶性好;树脂固化时橡胶中的不饱和双键反应可参与反应,并呈一定粒径的胶粒析出.本文研究了几种活性端基聚氨酯橡胶对不饱和聚酯树脂收缩控制的影响.

| Abstract: | Activated terminated polyurethane rubber(PU) is used to reduce shrinkage of unsaturated polyester resin(UP). Before UP curing, PU and UP can dissolve each other very well. During UP curing the unsaturated pairs in PU react with UP. Meanwhile, PU separates from the UP. The paper has studied the change of UP shrinkage caused by PU. |
