Title:
PHASE CHANGE ENERGY STORAGE MICROCAPSULE USING POLYURETHANE MODIFIED ORGANIC SILICONE RESIN AS SHELL MATERIAL, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/109891
Kind Code:
A1
Abstract:
A phase change energy storage microcapsule using a polyurethane modified organic silicone resin as a shell material, and a preparation method therefor. The preparation method comprises the following steps: (1) uniformly mixing monomers from which an organic silicone resin is generated, and adding a catalyst for prepolymerization to obtain a prepolymer of polysiloxane; (2) adding a urethane prepolymer to (1) and reacting to obtain a polyurethane modified organic silicone resin prepolymer; (3) uniformly mixing a core material with a shell material prepolymer to obtain a mixture of the core material and the shell material prepolymer; (4) formulating an aqueous solution of a surfactant; and (5) mixing the mixture of the core material and the shell material prepolymer with the aqueous solution of the surfactant and emulsifying same to obtain an emulsion, adding the catalyst until the reaction is ended, and separating and drying to obtain the phase change energy storage microcapsule having a polyurethane modified organic silicone resin shell.
