PAINT COMPOSITION IMPROVED OF FLEXIBILITY AND DURABILITY FOR SURFACE SIGN OF PAVED ROAD AND PAINTING METHODS USING THEREOF

摘要

Provided in the present invention is a road marking paint composition comprising 4-20 parts by weight of a styrene-based block copolymer; 4-15 parts by weight of ethylene vinyl acetate; 150-300 parts by weight of a pigment composed of calcium carbonate, dolomite, titanium dioxide, an azo compound or a mixture of the same; 100-270 parts by weight of high brightness glass balls; 2-15 parts by weight of a photostabilizer; 4-25 parts by weight of oil; and 2-20 parts by weight of polyethylene wax, based on 100 parts by weight of a binder resin composed of petroleum resin, modified maleic acid resin, or a mixture of the same. The road marking paint composition forms a coating film which is stable and has high durability by improving flexibility and durability, and provides high visibility to a driver and a pedestrian at night and in rain by improving abrasion resistance and retro-reflection performance.
