PRODUCTION METHOD FOR N-PARAFFIN LATENT HEAT STORAGE MATERIAL COMPOSITION, AND MICROCAPSULE HEAT STORAGE MATERIAL

摘要

Provided are: a latent heat storage material that functions as a high-capacity heat storage material in the low-mid temperature range by use of a latent heat storage material composition (hereinafter "n-paraffin latent heat storage material composition"), which comprises a total of 100 parts by mass of at least one C14-C18 n-paraffin, includes a C20-C24 n-alkyl alcohol and/or n-alkyl amine (hereinafter "n-paraffin derivative") as a supercooling prevention agent, and is obtained by performing step a) below, and then step b) below; a microcapsule heat storage material that includes the latent heat storage material as a core material; and production methods therefor. a) A step in which the n-paraffin derivative and the n-paraffin latent heat storage material composition are melted and homogenized in the 50-100°C temperature range. b) A step in which the homogenized solution obtained from the previous step is cooled, and the n-paraffin derivative precipitates in the n-paraffin latent heat storage material composition.
