Title:
VEHICULAR HEAT SHIELDING COMPONENT, HEAT SHIELDING FILM, AND METHOD FOR MANUFACTURING VEHICULAR HEAT SHIELDING COMPONENT
Document Type and Number:
WIPO Patent Application WO/2022/124349
Kind Code:
A1
Abstract:
Provided is a heat shielding film that is free from release or the like even where the heat shielding film is formed on a top surface of a piston and used in a severe environment such as the inside of an engine combustion chamber, and a vehicular heat shielding component on which the heat shielding film is formed. The vehicular heat shielding component of the present invention is one in which a heat shielding film (1) is formed on at least a part of the surface of a heat shielding target component (2) such as a piston of an engine to be given heat shielding properties. The heat shielding film (1) contains at least an inorganic compound layer (10) having a Vickers hardness (HV) of 50 to 100 in which one or a plurality of types of scale-like inorganic particles (12) selected from a group comprising mica, talc, and wollastonite are dispersed in an inorganic compound (11) formed of an alkoxide. By burning the inorganic compound layer (10) through irradiation of light having a wavelength of 500 nm or less, it is possible to increase the hardness of the inorganic compound layer (10) to 50 to 100 HV described above while suppressing an increase in temperature of the heat shielding target component (2).
