Title: PREPARATION METHOD FOR MICROCAPSULE FOR SELF-REPAIRING MATERIAL WITH PHENOLIC RESIN AS WALL MATERIAL
Abstract:
Provided are a microcapsule for a self-repairing material with a phenolic resin as a wall material and a preparation method thereof. The wall material of the microcapsule is a cross-linking cured phenolic resin and the core material is dicyclopentadiene. The preparation method for the microcapsule comprises the following steps: preparing a resol thermosetting resin to obtain a reaction liquid; preparing a core material emulsion; mixing the core material emulsion with the reaction liquid at 60-65°C to obtain a mixing solution; adjusting the pH value of the mixing solution to 2.5-1; increasing the temperature to 70-80°C and reacting for 1.5-2 hours; then increasing the temperature to 85-90°C and reacting for 1.5-2 hours, so as to obtain a microcapsule precipitate; filtrating same by suction and drying at 40-60°C, so as to obtain the microcapsule for a self-repairing material with a phenolic resin as the wall material.
