Solar-shielding fine particle dispersion and its manufacturing method, solar-shielding fine particle-containing masterbatch, and solar-shielding resin molded article using it, solar-shielding resin laminate

摘要

Solar-shielding fine particle dispersion containing solar-shielding fine particles and thermoplastic resin having high visible light transmission, excellent heat-shielding effect and stable weather resistance, solar-shielding fine-grained masterbatch, solar-shielding resin molded product, the above. Provided is a solar shielding resin laminate in which a molded product is laminated on another transparent molded product. A liquid solar-shielding fine particle dispersion in which a mixture of at least one selected from an organic solvent and a plasticizer and a solar-shielding fine particle is dispersed, or a powdery solar-shielding fine particle dispersion in which a liquid component is heat-removed from the dispersion. It is a solar-shielding fine particle dispersion dispersed in a resin component, and the solar-shielding fine particles are solar-shielding fine particles containing calcium lanthanum borohydride fine particles of the general formula CaxLa1-xBm, and the value of x in the general formula is 0. The value of 001 ≦ x ≦ 0.800 and m is 5.0 ≦ m 6.3, the average dispersed particle size is 1 nm or more and 800 nm or less, and the calcium lanthanum borohydride fine particles have a predetermined shape. Shielding fine particle dispersion.
