Abstract
The invention discloses a high-toughness ultraviolet-resistant aqueous copper zinc alloy powder. According to a preparation method, copolymerization modification is adopted for coating copper zinc alloy powder; acrylic acid, phenylethylene, and trihydroxymethylpropyl trimethylacrylate are taken as monomers, and other effective additives are added at the same time; at 80 DEG C, the surfaces of flake-like zinc alloy powder are coated with a layer of impact copolymer membranes with benzene rings and carboxy groups via copolymerization, wherein the shell layer formed on the surfaces possesses shielding effect on copper zinc alloy powder, and is capable of improving corrosion resistance and ultraviolet resistance of the copper zinc alloy powder, changing surface charge characteristics, functional characteristics, and surface chemical reaction characteristics of copper zinc alloy powder, and increasing toughness and strength. The high-toughness ultraviolet-resistant aqueous copper zinc alloy powder can be applied to water-based ink; color is bright; dispersity is excellent; hardening is not easily caused; and the high-toughness ultraviolet-resistant aqueous copper zinc alloy powder possesses wear resistance and ultraviolet resistance.
