Method for producing n-paraffin-based latent heat storage material composition and microcapsule heat storage material

摘要

It is a latent heat storage material composition (hereinafter referred to as “n-paraffin-based latent heat storage material composition”) consisting of 100 parts by mass of at least one n-paraffin having 14 to 18 carbon atoms, and as a supercooling inhibitor. , An “n-paraffin-based latent heat storage material composition” comprising an n-alkyl alcohol having 20 to 24 carbon atoms and / or an n-alkylamine (hereinafter referred to as “n-paraffin derivative”), and A latent heat storage material that functions as a high-capacity heat storage material in a medium to low temperature region by an n-paraffin-based latent heat storage material composition obtained by the following step a) and the subsequent step b), Provided are a microcapsule heat storage material included as a core material and a method for producing the same. a) A step of dissolving and homogenizing the n-paraffin derivative and the n-paraffin-based latent heat storage material composition in a temperature range of 50 to 100 ° C. b) A step of cooling the homogeneous solution obtained in the above step to precipitate an n-paraffin derivative in the n-paraffin latent heat storage material.
