摘要：用优化工艺合成环氧树脂－丙烯酸酯树脂的混合物乳液，在乳液中加入定量固化剂，形成了环氧树脂－丙烯酸酯ＩＰＮ材料。采用气相色谱（ＧＣ）测定乳液中的单体残留量，用凝胶渗透色谱（ＧＰＣ）证明乳液中环氧树脂的稳定存在。将最终形成的ＩＰＮ材料进行了力学性能和耐水性的测试分析，并以未形成ＩＰＮ结构的同组成样品的数据作对比，突出了该材料的优越性。最后，以热重分析（ＴＧＡ）和差示扫描量热分析（ＤＳＣ）的数据证明ＩＰＮ结构的形成有助于材料的玻璃化转变温度（Ｔｇ）和热分解温度（Ｔｄ）的提高。
The epoxy-polyacrylate emulsion with good stability, which could be easily formed IPN (interpenetrate polymer network) structure after added quantitative curing agtents at 30 ℃, was synthesized by optimum technology. The residual monomers of acrylate were measured by GC and the epoxy groups still remained in the emulsion through GPC were verified also. The tested results of mechanical properties and water resistant data proved the advantages of IPN material, compared with the general compounds which had the same composition. By means of TG and DSC analysis, it was also could be seen that the Tg and Td of polymer both be elevated if IPN structure formed.
