Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a high water-resistant electrostatic spray coating. Background technique

[0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic electric field to make negatively charged paint particles move in the direction opposite to the electric field, and adsorb the paint particles on the surface of the workpiece. Due to its high utilization rate, it can realize mechanization, automation, and assembly line The advantages of production, strong adhesion, smooth coating surface, small roughness, and little pollution to the environment have gradually replaced the traditional painting process in recent years. At present, the electrostatic spray coatings used in the market are mainly oil-based alkyd amino paints and acrylic paints, which have the disadvantage of poor water resistance during use, which limits the application of electrostatic spray coatings.
