Abstract

A highly wear-resistant water-based elastomeric coating for surface decoration of plastic materials, formulated by mixing an A agent as a resin base portion and a B agent as a curing agent portion at a certain ratio; wherein the A agent is obtained by stirring an aqueous polycarbonate polyurethane, an aqueous polyether polyurethane and an aqueous hydroxyacrylic acid, then adding deionized water and a neutralizer, stirring, then adding an aqueous dispersant, an aqueous wetting leveling agent, an aqueous wax slurry and an aqueous thixotropic agent, stirring, then adding an aqueous defoamer, and stirring; and the B agent is obtained by stirring a curing agent and a diluent. Compared with the prior art, fully water-based dispersion resins are selected as main binders to avoid the VOC problem caused by the high solvent volatilization of oil-based elastomeric coatings. The system VOC content is less than 200g\L, and meets the national environmental protection VOC control requirements.
