HIGH FUNTIONAL PAINT COMPOSITION FOR ROAD SURFACE SIGN HAVING EXCELLENT THERMOCHROMIC AND THERMO-SHIELD FUNCTION AND CONSTRUCTING METHOD FOR ROAD SURFACE SIGN USING THE SAME

摘要

The present invention relates to 100 parts by weight of an unsaturated polyester resin, 10 to 30 parts by weight of a thermochromic pigment, 30 to 50 parts by weight of a polyurethane resin, 30 to 50 parts by weight of an acrylate group-containing silane coupling agent, and 10 to 30 parts by weight of a hydrochromic dye. Containing 10 to 30 parts by weight of magnesium carbonate and 0.1 to 5 parts by weight of an ultraviolet stabilizer; The polyurethane resin, the acrylate group-containing silane coupling agent, the hydrochromic dye, and the magnesium carbonate include a core including an acrylate group-containing silane coupling agent, a hydrochromic dye, and magnesium carbonate; Using one having a micro-encapsulated structure consisting of; a porous polyurethane resin shell that surrounds the core and is foamed to have porosity; The present invention relates to a high-functional paint composition for road marking having excellent thermal color development and heat shielding performance, and a road marking construction method using the same.
