▎ 摘　　要

NOVELTY - A two-component urea-bond-containing coating composition comprises a main agent comprising 40-60 pts. wt. diethyl aspartate, 5-10 pts. wt. acrylate modified amine, a polyaspartic acid ester amine, a chain extender amine, 1-5 pts. wt. functionalized graphene oxide, 0.5-1.5 pts. wt. silane-modified amine, a pigment, and calcium carbonate, and a curing agent comprising an aliphatic polyisocyanate, an isocyanate prepolymer, and an isocyanate-functional component. USE - Two-component urea-bond-containing coating composition is used for forming coating film for marking pavement surface (claimed). ADVANTAGE - The two-component urea-bond-containing coating composition has excellent adhesiveness with glass beads, so it has the effect of maintaining more than 400 mcd/m2.lx in retroreflective performance after 4 million cycles of abrasion resistance, and marks pavement surface with high mechanical property, excellent durability and visibility. Due to its excellent moisture resistance, it is possible to stably maintain the performance of the coating film for pavement marking even in an environment exposed to humid weather such as snow or rain. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for construction method for forming a coating film for marking pavement surface, which involves forming a coating surface by spraying the two-component urea-bond-containing coating composition on the road surface, and mixing 60-80% low refractive index glass beads with a relative refractive index of 1.13-1.43 and 20-40% high refractive index glass beads with a relative refractive index of 1.43-1.8 in the wet film before solidification.
