Title:
RESIN COMPOSITION CONTAINING TITANIUM OXIDE HAVING HEAT STORAGE AND RADIATION PROPERTIES, AND HEAT STORAGE MATERIAL OBTAINED USING SAID RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2018/174210
Kind Code:
A1
Abstract:
The present invention provides a heat storage material in which a titanium oxide having heat storage and radiation properties is dispersed in a molded article of a resin having a glass transition temperature of 460K or higher, wherein: the titanium oxide having heat storage and radiation properties has the composition Ti3O5; when the titanium oxide having heat storage and radiation properties is heated or irradiated with light and reaches a temperature of 460K or higher, a β phase transitions to a λ phase; the λ phase does not transition to the β phase when in a temperature range less than 460K, but rather remains as a λ phase; and the λ phase transitions to the β phase when pressure is applied, at which time transition heat is radiated. The heat storage material according to the present invention thereby involves application of lower pressure than conventionally required, whereby the crystal structure of the titanium oxide having heat storage and radiation properties included in the heat storage material can be changed at a desired time, and transition heat can be released in accompaniment therewith, the heat storage material of the present invention also having exceptional utility and durability.
