METHOD OF MANUFACTURING MICROENCAPSULATED PHASE-CHANGE MATERIAL-CONTAINING GYPSUM PLATE CAPABLE OF FLAME RETARDATION AND TEMPERATURE VARIATION ATTENUATION

摘要

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. Due to the microencapsulated phase-change material, dispersing agent, and foaming agent, gas generated from the microencapsulated phase-change material heated at high temperature is quickly discharged from the gypsum plate without destructing original structure thereof.
