<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a microcapsule of a thermal storage medium stable to a long-term heat history and share stress by a pump, by which an expensive device such as a pressurized closed container is not needed even when the microcapsule uses a thermal storage medium having a high melting point and to provide the microcapsule of the thermal storage medium. <P>SOLUTION: In the manufacturing method of the microcapsule of the thermal storage medium, an organic solvent solution in which a resin (A1) having an acid group and a hydrolyzable silyl group and an aliphatic hydrocarbon based thermal storage medium (B) are dissolved in an organic solvent (C) and a basic compound (D) are mixed and the acid group in the resin (A1) is neutralized to form a resin (A2) having the neutralized acid group and the hydrolyzable silyl group, then the resultant material and water are mixed to be subjected to phase inversion emulsification, then the hydrolyzable silyl group in the resin (A2) is subjected to hydrolytic condensation and then the organic solvent (C) is removed. The microcapsule manufactured by the manufacturing method is also provided. <P>COPYRIGHT: (C)2009,JPO&INPIT |
