【摘要】 采用E-Ⅱ型乳化剂和相反转技术制备水溶性双酚A型环氧树脂乳液,研究了乳化剂的用量、乳化时间、搅拌速率和乳化温度对乳液稳定性的影响。得出了最佳乳化工艺条件:乳化剂质量分数为7.25%~8.0%、乳化温度为60~70℃、搅拌速度为700~900 r/min、乳化时间为40~50 min。采用激光粒度衍射分析仪表征了水溶性环氧乳液的粒径为400~500 nm。更多还原

【Abstract】 Using self-synthesized E-Ⅱemulsifier the waterborne bisphenol-A epoxy resin emulsion was prepared by phase inversion technology.Effect of emulsification temperature,emulsification time,emulsifier concentration and shear rate on the stability of prepared waterborne bisphenol-A epoxy resin emulsion was discussed and analyzed.The optimum preparation condition of the waterborne bisphenol-A epoxy resin emulsion are as follows:emulsification temperature of 60～70 ℃,emulsification time of 40～50 min,emulsifier concentration of 7.25%～8.0% and the shear rate of 700～900 r/min.And the particle diameter of the waterborne bisphenol-A epoxy resin emulsion was about 400～500 nm from laser diffraction particle size analyzer.更多还原
