  • METHOD OF MANUFACTURING MICROENCAPSULATED PHASE-CHANGE MATERIAL-CONTAINING GYPSUM PLATE CAPABLE OF FLAME RETARDATION AND TEMPERATURE VARIATION ATTENUATION
    Publication number: 20150329783
    Abstract: A method of manufacturing a microencapsulated phase-change material-containing gypsum plate capable of flame retardation and temperature variation attenuation is introduced, such that an organic microencapsulated phase-change material is uniformly distributed in an inorganic gypsum plate. The method involves putting a microencapsulated phase-change material in a dispersing agent solution, blending the dispersing agent solution to form a first solution, putting the foaming agent in the first solution, putting gypsum powder and starch in the first solution, blending the first solution to form a microencapsulated phase-change material gypsum mixture solution, molding the microencapsulated phase-change material gypsum mixture solution to finalize the manufacturing of a microencapsulated phase-change material-containing gypsum plate capable of flame retardation and temperature variation attenuation.

  • Phase-changing material microcapsules by using PMMA prepolymer and organic-solvent free synthesis process
    Patent number: 9150769
    Abstract: Phase change material microcapsules are obtained using a PMMA prepolymer and an organic-solvent free synthesis process. A polymer monomer and an initiator are subject to pre-polymerization in a water bath to form Polymethyl methacrylate (PMMA) prepolymer which is then prepared to be a stabilizer aqueous solution. A phase change material is added to the stabilizer aqueous solution and liquefied in advance, and stirred to form an emulsion by a homogenizing mixer. A starting agent, a cross-linking agent and a Polymethyl methacrylate methyl ester prepolymer are added to the emulsion containing the phase-change material. The emulsion is further stirred by the homogenizing mixer for micro-emulsification which then aggregates in water bath.
