以环氧树脂E-44、2-氨基-5-磺酸基苯甲酸、乙二醇丁醚和正丁醇为原料,合成一种新型阴离子环氧乳化剂EP-D；同时,E-44和聚乙二醇6000(PEG6000)以摩尔比2∶1反应,合成端环氧基非离子环氧乳化剂EP-PEG；将EP-D与EP-PEG按不同质量比复配获得不同配比的EP-D/EP-PEG水性环氧复合乳化剂.分别研究了EP-D/EP-PEG及EP-PEG在环氧树脂中加入质量分数为6％～12％时的乳化性能及形成乳液的表面张力、电导率和胶粒的Zeta电位、粒径.结果表明,当EP-D和EP-PEG以质量比3∶5复配,总加入质量分数为9％时,制备的环氧乳液性能最佳.与EP-PEG形成的环氧乳液相比,复配环氧乳化剂用量少,乳液铺展性好、稳定性高,且乳液在相反转时的固含量提高了10％以上.复配环氧树脂乳液中胶粒的Zeta电位为-41.9 mV、粒径为342 nm、表面张力为25.5 mN/m、粘度为14 mPa·s.这表明利用乳化剂EP-D与EP-PEG复配新合成的EP-D/EP-PEG水性环氧复合乳化剂可制备稳定性好,固含量高的乳液.
