Process for Production of Resin-Coated Heat Accumulator Particles

The present invention provides a method of producing resin-coated latent heat storage particles which can be continuously supplied to a producing step of a water-curable-type inorganic material (gypsum, cement, and the like), with a latent heat storage component in the particles hard to volatilize.The above-mentioned method is a method of producing particles comprising a step of dispersing a latent heat storage component, isocyanate, and porous particles in water under stirring condition, said particles comprising as core said latent heat storage component and as shell a resin.
