CN101659781A 一种环氧树脂微粒子、分散液及其制备方法 无效 - 撤回

一种环氧树脂微粒子、分散液及其制备方法
摘要：
本发明公开了一种环氧树脂微粒子，该微粒子由环氧树脂在固化剂的作用下固化而成，其平均粒径为50-400nm。本发明还公开了一种由环氧树脂微粒子、表面活性剂、固化剂和水组成的环氧树脂微粒子的分散液。本发明还公开了一种环氧树脂微粒子的分散液的制备方法。本发明采用聚氧乙烯醚及其衍生物作为环氧树脂的表面活性剂，由于其具有更合适的HLB值(亲水疏水平衡值)，通过与环氧树脂微粒子之间的相互作用，使得获得的水分散液具有长期分散稳定特性，可在涂料、粘合剂、精细化工助剂等领域获得广泛应用。本发明所得的环氧树脂微粒子粒度小且粒径分布窄。
摘要（英）：

The invention discloses an epoxy resin micro-particle. The micro-particle is prepared by curing epoxy resin under the function of a curing agent, and has an average grain size of between 50 and 400nm.The invention also discloses a dispersion liquid for the epoxy resin micro-particle consisting of the epoxy resin micro-particle, a surfactant, the curing agent and water. The invention also discloses a method for preparing the dispersion liquid for the epoxy resin micro-particle. The method uses polyethenoxy ether and a derivative thereof as the surfactant for the epoxy resin; since the surfactant has a more appropriate HLB value (a hydrophobicity-hydrophilicity balance value), through the interaction between the surfactant and the epoxy resin micro-particle, the prepared aqueous dispersionliquid has long-term dispersion stability and can be widely applied in the fields such as coatings, adhesives and fine chemical additives. The epoxy resin micro-particle prepared by the method has small granularity and narrow particle size distribution.
