Preparation and Characteristics of Non-ionic Waterborne Emulsifier from Terpinene-maleic Ester Type Epoxy Resin
摘要
Abstract
A series of emulsifiers from terpinene-maleic ester type epoxy resin (TME) were prepared by TME modified with polyethylene glycol (PEG),and the emulsifiers were used to prepare waterborne TME emulsion (WTME) by phase-inversion emulsification.Influences of relative molecular mass (M_r) of PEG,molar ratio of TME to PEG,reaction temperature and time on solubility,surface activity,weight-average relative molecular mass (M_w) of the emulsifier,and particle size distribution,centrifugal stability and viscosity of the emulsion were investigated.It was shown from the results that emulsifier TP- V which was prepared by PEG 4000 reacted with TME,in the molar ratio of TME to PEG 2:1,at about 110 ℃ for 1 h,catalyzed by boron trifluoride diethyl etherate,has a very good emulsifying impact for TME.Particle size distribution of the emulsion was homogeneous and viscosity of the emulsion was small.It was shown from the TEM results that the particles of dilute waterborne TME emulsion which was prepared from emulsifier TP- V,could be dispersed stably in water,under the action of the interfacial layer,which was composed of hydrated electric double layer with the composition of emulsifier and adsorbed water,and adsorbed on the surface of the particles.The particle diameter was less than 200 nm.关键词
