| description | The invention discloses an emulsifier for preparing a low-viscosity waterborne epoxy emulsion, a preparation method of the emulsifier and the waterborne epoxy emulsion containing the emulsifier. The emulsifying agent is relatively good in hydrophilicity and excellent in emulsifying effect. The preparation method of the emulsifier comprises the following steps: (1) taking resorcinol and trimethylolpropane triglycidyl silicone oil ether as raw materials, taking tetrabutylammonium bromide as a catalyst, and reacting for a certain time to prepare branched epoxy resin; (2) purification treatment of the resin, wherein hot water washing and ethanol water washing are mainly adopted; (3) drying treatment of epoxy resin; and (4) carrying out ring-opening polymerization on the branched epoxy resin and polyethylene glycol in a certain molar ratio. The emulsifier does not contain an organic solvent, has low viscosity, is beneficial to construction and is simple in preparation process.
