摘要/Abstract

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)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500～900 r/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100～440 nm,黏度 850 mPa·s,环氧值 0.11mol/100g。

Abstract: 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), 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 500-900r/min, and solid content about 45%. Under these conditions, particle diameter of the emulsion is among 100-400nm, average particle size is about 200 nm, and viscosity is about 850mPa·s, epoxy value is 0.11mol/100g.
