PREPARATION AND PROPERTIES OF SELF-EMULSIFIED CATIONIC WATERBORNE EPOXY RESIN MODIFIED SIZING AGENT
This article reports a preparation and properties of self-emulsified cationic waterborne epoxy modified resin as a film former of sizing agent.There were two major steps to prepare cationic waterborne epoxy modified emulsion polymers.The first step was to synthesize a linear polymer containing tertiary amine in its main chain by the reaction of epoxy resin with hydrophobic primary aliphatic/aromatic amine and hydrophilic polyetheramine.The second step was to neutralize the polymer synthesized in the first step by acetic acid to produce a cationic polymer and then dispersed it into water to produce cationic waterborne emulsion polymer.A series of parallel experiments of synthetic reaction between epoxy resin and mixture of two kinds of primary amine were completed and the optimal reaction temperature and time were concluded as 110℃ and 3 hours respectively.The amphiphilic properties of cationic waterborne epoxy modified emulsion polymers were adjusted by the ratio of the primary aliphatic/aromatic amine with polyetheramine.The particle size of epoxy modified emulsion polymers prepared in this paper was small and controllable.The emulsion stability was good and was stored at room temperature for more than three months and there was no precipitation and phase separation.
