摘要
研究了纳米CaCO3对不饱和聚酯树脂(UP)体积收缩性能的影响及其作用机理。结果表明,随着纳米CaCO3用量的增加,UP/纳米CaCO3复合材料的体积收缩率先下降后上升;用不同偶联剂对填料进行表面处理后,复合材料的体积收缩率较未用偶联剂处理的复合材料低,且用偶联剂硬脂酸处理填料比用偶联剂KH-570更有利于复合材料体积收缩率的下降。
The effect and mechanism of nano-CaCO3 on the volume shrinkage of the unsaturated polyester（UP） was studied. With the increasing of the fillers in the UP/CaCO3 composites, the volume shrinkage ratio of the composites was decreased first, and then increased. Comparing with the composites obtained with the CaCO3 fillers untreated with coupling agent, the composites obtained with the CaCO3 fillers treated with different coupling agent had smaller volume shrinkage ratio. The volume shrinkage ratio of composites applied with coupling agent stearic acid was lower than that of composites applied with coupling agent KH -570.
