摘要:以自制的聚乙二醇改性萜烯酯型环氧树脂(TP)为乳化剂,采用相反转法乳化萜烯酯型环氧树脂制备了环氧树脂水乳液,分析了乳化过程中体系电导率变化与微观形态转变的关系,讨论了乳化剂质量分数、乳化温度、搅拌速度、乳液固含量等条件对乳液粒子体积平均粒径(D[4,3])及粒径分布一致性、黏度、离心稳定性、环氧值及环氧保留率等乳液性质的影响。实验结果表明,该环氧树脂乳液的最佳制备条件为:TP质量分数16.7%,乳化温度60℃,机械搅拌速度500~900r/min,固含量约45%。在该条件下制备的乳液性质最好,乳液粒子体积平均粒径约200nm,粒径分布100~440nm,黏度850mPa.s,环氧值0.11mol/100g。
A water-emulsified terpinene-maleic ester type epoxy resin (TME) was prepared by phase-inversion emulsification, and a self-designed emulsifier prepared by TME modified with PEG was used as reactive emulsifier in this emulsion. The relationship between conductivity and micro-morphology in the emulsifying process was analyzed. The influences of the emulsifier mass fraction, emulsifying temperature, stirring speed on the volume average particle diameter (D[4,3 ] ), consistency of particle size distribution, centrifugal stability and viscosity of the emulsion were also discussed. The results show that the optimum conditions for preparing this type of water-emulsified epoxy resin were as follows: emulsifier mass fraction 16.7 %, at 60℃ and 500- 900 r/min, and solid content about 45 %. Under these conditions, particle diameter of the emulsion is among 100-400 nm, average particle size is about 200 nm, and viscosity is about 850 mPa·s, epoxy value is 0.11 mol/100 g.
