To transmit the solar radiation shielding resin backing material and the solar radiation shielding compound backing material null visible light which can making use of the particulate dispersing element and the solar radiation shielding resin material which for the solar radiation shielding are used for the production of the solar radiation shielding resin material and the solar radiation shielding resin material where the particulate and this particulate for the solar radiation shielding

摘要

PPROBLEM TO BE SOLVED: To provide solar radiation shielding particulates having transmission performance of a high solar radiation shielding function and a high visible light region and having a color tone of blue, a solar radiation shielding resin material dispersed with the particulates in the resin component, and a solar radiation shielding particulate dispersing element used for manufacturing the solar radiation shielding resin material, and a solar radiation shielding resin base material and solar radiation shielding composite base material obtained by using the solar radiation shielding resin material. PSOLUTION: The solar radiation shielding particulates are composed of titanium nitride particulates which have a crystal structure of a face-centered cubic crystal of 0.423 nm in lattice constant, is 250 nm in average grain size, and is L*=35 to 60, a*=-0.1 to 10.0, and b*=-0.5 to 15.0 in powder color due to diffused reflected light in an L*a*b* color system. Also, the solar radiation shielding resin material is prepared by dispersing the solar radiation shielding particulates into the resin component. The solar radiation shielding resin base material and the solar radiation shielding composite base material are obtained by molding the solar radiation shielding resin material.
