  • Publication number: 20220298401
    Abstract: An object of the present invention is to provide a latent heat storage body which has a melting point of about 300 to 550° C. and is difficult to cause leakage of a phase changing material, and a product obtained by applying the body. Provided is a microcapsule for latent heat storage materials including a metal core containing Zn and Al and a shell covering the metal core. The shell of the microcapsule includes an oxide film containing Zn and O, and an oxide film containing Al and O adjacent to an inner side of the oxide film. In the microcapsule, a mass ratio of ZnAl2O4 is 4% or less. The mass ratio is determined by analyzing the microcapsule by an XRD (X-ray diffractometer) device and subjecting results to quantitative analysis using a RIR (Reference Integrity Ratio) method.

  • Patent number: 10894907
    Abstract: In the present invention, after a primary coating film is formed by boehmite treatment of the surface of a core particle in a solution comprising Al ions, a secondary coating film is formed by cooling the solution to the supersaturation temperature of the Al ions to cause deposition of a hydroxide of aluminum on the surface of the primary coating film, and an Al oxide film is formed on the surface of the core particle by heat treating the secondary coating film in an oxidizing atmosphere. Consequently, the shell is thickened by the amount of secondary coating film formed, so that the cyclic strength of the capsule can be secured and the composition change of the PCM in the production process is remarkably suppressed.

  • Patent number: 10563108
    Abstract: In the latent heat storage body (100) according to the present invention, the surface of a core particle (10) composed of a latent heat storage material of a metal or an alloy is coated with an oxidized film of a compositional element of the core particle (10). Hence, the step of separately fabricating the core particle and the oxidized film (20) corresponding to a shell accommodating the core particle and accommodating the core particle inside the shell becomes unnecessary. Further since the core particle exhibits no expansion when transforming from a solid phase to a liquid phase, the component of the melted latent heat storage material stays inside the space covered with the oxidized film and the oxidized film is never damaged. Further, the oxidized film (20) can be made chemically stable.
