摘要

The present invention provides a silane-modified acrylic resin having a weight average molecular weight of 35,000 to 50,000 g/mol and a glass transition temperature (T _g ) of 35 to 50°C, and a fluorine-modified acrylic resin having a weight average molecular weight of 30,000 to 100,000 g/mol. Performance improvement binder comprising a resin mixture, silica, pigments and curing accelerator containing 50 to 90% by weight; 5-40% by weight of a modified filler containing heavy calcium carbonate, barium sulfate, potassium oxide, magnesium fluoride, fine ceramics, silica sand, and pigments; 1 to 20% by weight of an anti-icing agent including 70 to 90% by weight of sodium chloride, 1 to 20% by weight of calcium chloride, and 3 to 20% by weight of a silicone compound in the total weight of the anti-freezing agent; And curing agent 0.1 to 5% by weight; relates to a coating composition for road pavement comprising a.
