HEAT RAY SHIELDING POLYCARBONATE SHEET, HEAT RAY SHIELDING POLYCARBONATE SHEET LAMINATE, AND MANUFACTURING METHOD FOR HEAT RAY SHIELDING POLYCARBONATE SHEET

摘要

PROBLEM TO BE SOLVED: To provide a polycarbonate sheet to be manufactured in a simple method without the need of using a physical film forming method of a high cost while performing a high heat ray shielding ability by absorbing a heat ray of a 800 to 2,500 nm wavelength (near infrared ray) while maintaining excellent visible ray transmitting ability so as to achieve various shapes with a heat ray shielding function.SOLUTION: The heat ray shielding polycarbonate sheet includes as a heat ray shielding component at least lanthanum hexaboride fine particles and antimony-added tin oxide fine particles. The weight ratio of the lanthanum hexaboride fine particles and the antimony-added tin oxide fine particles is in a range of 2/100lanthanum hexaboride fine particles/antimony-added tin oxide fine particles15/100. A high heat resistant dispersant having an acrylic main chain of a 230°C or higher thermal decomposition temperature is included therein. The weight ratio of the high heat resistant dispersant and the heat ray shielding component is in a range of 0.5dispersant/heat ray shielding component10.
