A modified epoxy resin composition obtainable by:
i) reacting one or more epoxy resin compound(s) with a dibasic acid, to obtain an epoxy group conversion of from 10 to 70%, and
ii) reacting the resulting dibasic ester group containing epoxy resin with a trihydric primary aliphatic alcohol having of from 5 to 12 carbon atoms, to obtain a conversion of remaining epoxy groups of from 30 to 80%.
Said modified epoxy resin compositions have high reactivity and provide cured products having a good balance of adhesion, flexibility and impact strength.
一种改性环氧树脂组合物,可通过以下方法获得
i) 将一种或多种环氧树脂化合物与二元酸反应,以获得 10%至 70%的环氧基 转化率,以及
ii) 将得到的含有二盐基酯基团的环氧树脂与具有 5 至 12 个碳原子的三水伯脂肪 醇反应,以获得 30%至 80%的剩余环氧基团转化率。
上述改性环氧树脂组合物具有很高的反应活性,固化后的产品在粘附性、柔韧性和抗冲击强度之间具有很好的平衡。
