COMPOSITION FOR MANUFACTURING HEAT RAY-SHIELDING VINYL CHLORIDE FILM AND METHOD OF MANUFACTURING THE SAME, AND HEAT RAY-SHIELDING VINYL CHLORIDE FILM

摘要

PROBLEM TO BE SOLVED: To provide a composition for manufacturing a heat ray-shielding vinyl chloride film which can apply to an ordinary vinyl chloride film manufacturing process and method of manufacturing the same.

SOLUTION: The method of manufacturing the composition for manufacturing a heat ray-shielding vinyl chloride film comprises: a process of obtaining a dispersion liquid by dispersing into an organic solvent tungsten oxide fine particles represented by the general formula, WOxand/or multiple tungsten oxide fine particles represented by the general formula, MyWOzand having a hexagonal crystal structure, and a dispersant; a process of obtaining a mixture by mixing the dispersion liquid with a plasticizer for manufacturing a vinyl chloride film; and a process of obtaining the composition for manufacturing the heat ray-shielding vinyl chloride film by removing the organic solvent until to a concentration of the solvent of not greater than 5 wt.% by a vacuum distillation method.
