Anti-dazzle coating composition, and preparation and application thereof

A related anti-dazzle coating composition comprises a) a base material; b) a nanometer-level core shell structural microballoon which accounts for 1-10% by mass of the coating composition and used as an anti-dazzle modifier, wherein the core of the microballoon is one or more selected from nanometer SiO2, nanometer CaCO3 and nanometer poly(C1-C8 alkyl methacrylate), and the shell material is polystyrene and/or polymethyl methacrylate; and c) an other optional coating auxiliary agent. Compared with conventional anti-dazzle modified coating compositions, the coating composition helps to substantially reduce dazzle, and the transparency of a coating layer is substantially improved. The invention also relates to a preparation method of the coating composition and application of the coating composition to provide an anti-dazzle coating layer, and especially application to provide an anti-dazzle coating layer for road isolation strips or tunnels.
