| Abstract: | 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. |
