摘　　要：以蒙脱石为原料,通过HDTMAB改性制备纳米粘土,得到的最佳制备条件为:反应温度90℃,矿浆浓度5%,反应时间2h。在环氧树脂中加入5重量份纳米粘土,制得的纳米粘土/环氧树脂复合材料的冲击强度和弯曲强度,分别比纯环氧树脂提高303.2%和45.5%。实验证明纳米粘土对环氧树脂具有显著的增韧和增强效果。It prepared nano-clay with montmorillonite used as raw material and modified by HDTMAB, and obtained the optimal preparation conditions: reaction temperature is 90℃, pulp concentration of montmorillonite is 5pph and reaction time is 2h. The impact strength and bending strength of epoxy resin with the addition of 5% nano-clay are increased by 303.2% and 45.5% over the pure epoxy resin respectively. The experiment results showed that the nano-clay has strong toughening and reinforcing effects on epoxy resin.
