摘　　要：采用DSC仪器研究双组份聚氨酯复合材料的反应过程,发现填料改性蒙脱土不仅能增强聚氨酯的物理性能,而且影响该体系的反应速度。实验结果表明:填料量3%为平衡点,应力-应变实验结果表明改性蒙脱土对于聚氨酯具有软增强效果,反应过程也受填料量影响,含量低于3%时,随含量提高,反应速度上升;大于3%时,反应速度随之下降。The curing process of polyurethane composite were studied by DSC. The organoclay affects the strength of the polyurethane at break. It is also a promoting effect on the react rate. This key point was about 3% filler in the polyurethane composite system. The results express that organoclay has reinforce effect without affecting modules increase. When the organoclay content is 3% or less, the catalyst effect is obvious, after 3% point, the catalyst effect decrease.
