Title:
COMBINED STRUCTURE FOR SOLAR RADIATION SHIELDING AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/054497
Kind Code:
A1
Abstract:
Provided is a combined structure for solar radiation shielding, which uses solar radiation shielding fine particles that have high visible light transmittance, excellent solar radiation shielding characteristics and weather resistance at the same time, and which thus has high visible light transmittance, solar radiation shielding characteristics and low haze value, while having high environmental stability and low production cost. The present invention provides a combined structure for solar radiation shielding, which is obtained by sandwiching an intermediate layer that comprises one or more intermediate films which are selected from among a resin sheet that contains solar radiation shielding fine particles and a resin film that contains solar radiation shielding fine particles between two combining plates which are selected from among a plate glass that does not contain solar radiation shielding fine particles and a resin board that does not contain solar radiation shielding fine particles. This combined structure for solar radiation shielding is a solar radiation shielding fine particle dispersion which is configured such that: the solar radiation shielding fine particles contain calcium lanthanum boride fine particles represented by general formula CaxLa1-xBm, wherein x satisfies 0.001 ≤ x ≤ 0.800 and m satisfies 5.0 ≤ m < 6.3; the calcium lanthanum boride fine particles have an average dispersed particle diameter of from 1 nm to 800 nm (inclusive); and the calcium lanthanum boride fine particles have a predetermined shape.
