Problems solved by technology

The existing water-based chlorine-biased coatings are all one-component products. After the coating is hard-dried, it has good dielectric shielding performance, but it has the problems of low mechanical strength and low adhesion to the substrate, and it is easy to be scratched and cause coating damage. Defects affect the anti-corrosion effect

Abstract

The invention provides a manufacturing method of a double-component cationoid normal-temperature cross-linked water-based chlorine partial metal anti-corrosion coating. The manufacturing method is characterized in that the coating comprises a component A and a component B, wherein the component A is chlorine partial latex, which is prepared by polymerizing a vinylidene chloride monomer and a acrylate monomer high-pressure emulsion containing an acetoacetic acid group; and the component B is a composition of a nanometer anti-rust pigment, a filler, a water-based amine cross-linking agent, a water-based hydrazide cross-linking agent, water and an auxiliary. During use, the component A and the component B are mixed and uniformly stirred; in the film forming process, an acetoacetic acid group can react with metal ions in base metal, metal ions in the nanometer anti-rust pigment and the cross-linking agents and can be cross-linked with the metal ions in the base metal, the metal ions in the nanometer anti-rust pigment and the cross-linking agents so as to form a compact coating; the problem that the mechanical performance of a common chlorine partial coating is solved; binding forces and adhesion forces between the coating resin and the base material and between the resin and the filler are further enhanced; the environment friendliness and better medium shielding performance are kept; and the excellent corrosion resistant function is also obtained.

Description

technical field [0001] The invention relates to a method for manufacturing a water-based chlorine-biased metal anti-corrosion coating, in particular to a method for manufacturing a two-component normal-temperature cross-linked water-based chlorine-biased metal anti-corrosion coating containing acetyl groups for water-based metal anti-corrosion coatings. Background technique [0002] Water-based coatings are safe and environmentally friendly, and are used to replace heavily polluted solvent-based coatings, and are widely used in many fields. In the field of metal anti-corrosion coatings, the water-based resins that are currently studied mainly include water-based acrylate resins, water-based epoxy resins, water-based polyurethane resins, water-based fluorocarbon resins, water-based inorganic silicate resins, and water-based chlorine partial resins. Among them, chlorine Partial resin has dense film formation and low water absorption, and the coating has excellent alkali resist...
