摘　　要：以纳米蒙脱土为原料,采用插层聚合法制备了改性增韧环氧树脂。通过正交实验考查了混合时间、混合温度、蒙脱土类型、蒙脱土含量对改性环氧树脂断裂伸长率的影响。实验结果表明混合时间对改性环氧树脂的断裂伸长率影响最大,当混合时间为2h,混合温度为70℃,采用DK1类型的蒙脱土,添加量为2%时,制备的改性环氧树脂断裂伸长率为12.11%,冲击强度为13.61MPa。The modified toughened epoxy resin was prepared with using nano montmorillonite as materials by intercalation polymerization method. The effects of reaction temperature, reaction time, montmorillonite type and content on the elongation at break of the modified epoxy resin were investigated by orthogonal experiment. The results showed that reaction time had a great effect on elongation at break of the modified epoxy resin. When the reaction temperature was 70℃, reaction time was 2h, montmorillonite type was DK1 and content was 2%, the elongation at breaking of the modified epoxy resin was up to 12.11% and the impact strength was 13.61MPa.
