MULTI-FUNCTIONAL PAINT COMPOSITION AND METHOD OF MANUFACTURING PAINT FILM USING THE SAME

摘要

PURPOSE: A paint composition is provided to increase solar heat-reflecting and heat-radiating effect, to exhibit heat-insulating effect and to reduce energy consumption. CONSTITUTION: A paint composition comprises 0.3-5 weight% of a powder polymer which has an average particle diameter of 10-150 micron, has a hollow sphere shape with a core portion filled with air and the surface coated with calcium carbonate; 2-15 weight% of a heat-shielding color pigment, 40-75 weight% of a resin binder, 10-45 weight% of a filling pigment, 1-10 weight% of an additive and diluent. The resin binder is at least one selected from a polyurethane resin, a polyurea resin and polyether resin. [Reference numerals] (AA) Solar light reflection; (BB) Concrete/asphalt; (CC) Heat insulation
