Water-based bronze-like coating and application thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based imitation copper coating and its application in the manufacture of imitation copper doors. Background technique [0002] The imitation copper door is made of electrolytic plates, and the surface is sprayed with paint with a color similar to that of the copper door to make it look similar to the copper door, so it is called an imitation copper door. In order to achieve a beautiful and durable effect, most of the domestic anti-theft doors are made of imitation copper doors, and most of them adopt pickling and phosphating process before painting. Plates, forgings and cold plates are welded together, which causes certain difficulties for spraying, so a primer for degreasing and rust removal is required in the early stage. First: Primer. At present, most enterprises use electrostatic powder spraying as primer. Second: finish paint, which is now basically i...
