Description
Technical Field
The invention belongs to the field of coatings, and particularly relates to an anti-corrosion powder coating and a preparation method thereof.
Background
The powder coating is a solid powder synthetic resin coating composed of solid resin, pigment, filler, auxiliary agent and the like. Unlike conventional solvent-based coatings and water-based coatings, the dispersion medium is not a solvent and water, but air. It has the characteristics of no solvent pollution, 100 percent film forming and low energy consumption. Powder coatings fall into two broad categories, thermoplastic and thermosetting. The appearance (luster and leveling property) of a coating film of the thermoplastic powder coating is poor, and the adhesion between the thermoplastic powder coating and metal is also poor, so the thermoplastic powder coating is rarely applied in the field of automobile coating. The appearance, various mechanical properties and corrosion resistance of a paint film formed by the paint can meet the requirements of automobile coating. The polyethylene powder coating has excellent corrosion resistance, chemical resistance, electrical insulation and ultraviolet radiation resistance. The disadvantages are low mechanical strength and poor adhesion to the substrate. Can be used for chemical tank, impeller, pump, inner wall of pipeline, meter shell, metal plate, screen plate in refrigerator, automobile parts, etc.
