PURPOSE: A paint composition for thermo-shielding is provided to prevent yellowing phenomenon, to reduce drying time, and to improve alkali resistance and weatherability. CONSTITUTION: A paint composition for thermo-shielding comprises 15-46 parts by weight of an aqueous acrylic emulsion and aqueous epoxy resin which is a curing agent; 5-20 parts by weight of a heat-shielding and insulating material coated with hydrophobic material; and 0.1-40 parts by weight of additives. Application method of the heat-shielding and insulating aqueous material consists of a step of reinforcing the bottom side by spreading aqueous emulsion primer on the concrete; and a step of spreading the aqueous paint composition to form a heat-shielding and insulating layer. |
