The invention belongs to the technical field of coatings and in particular relates to a water-based
bronze-like
coating and application thereof to manufacturing of a
bronze-like door. The water-based
bronze-like
coating of the invention consists of a bronze
powder emulsion and a wire-drawing black, wherein the bronze
powder emulsion comprises the following components in part by weight: 50 to 60 parts of bronze
powder, 120 to 130 parts of white latex and 95 to 105 parts of bone glue solution which contains 2
mass percent of bone glue; and the wire-drawing black comprises the following components in part by weight: 10 to 20 parts of black colour paste, 25 to 35 parts of white latex, 35 to 45 parts of bone glue solution which contains 2
mass percent of bone glue, 100 parts of water and 4 to 6 parts of
ethanol. The method for manufacturing the bronze-like door by using the water-based bronze-like
coating comprises the following steps of: a, performing routine pretreatment on the surface of a steel door to make the surface of the
metal clean, smooth and flat; and b, uniformly coating the bronze powder
emulsion on the surface of the steel door, wherein the thickness of the bronze powder emulsion layer on the surface of the steel door is 0.2 to 0.3mm,
drying the bronze powder emulsion layer, coating the wire-drawing black onto the bronze powder emulsion layer, after
drying the wire-drawing black, drawing wire, and glaring. In the invention, the water-based coating is adopted to manufacture the bronze-like door and only two times of baking are needed, so that the cost is relatively low and the process is environmentally-friendly.
