<p>A method for preparing an epoxy microcapsule by using phenolic resin as a wall material comprises the following steps: mixing epoxy resin, an emulsifier and water, and stirring to prepare an emulsion; adding phenol, aldehyde and a pH regulator I into the emulsion, adjusting a pH value to 7 to 9, and stirring; and then, adding polyphenol, a curing accelerator and a pH regulator II to the obtained solution, adjusting the pH value to 2 to 4, reacting for 2 to 3 hours, cooling, standing, filtering and drying to obtain an epoxy microcapsule using the phenolic resin as a wall material. By means of the preparation method, a curing reaction between the wall material and a core material is avoided, and the epoxy microcapsule using the phenolic resin as the wall material, which have a good form and a high coating rate, is successfully synthesized.</p> |
