Problems solved by technology

At present, the water-based resins that have been studied more 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. Alkaline, superior water resistance and moisture resistance, will be more and more valued, but the existing chlorine partial coatings are mostly stabilized by adding a large amount of anionic emulsifiers to stabilize the latex of chlorine partial polymers, and mechanical Poor stability, adverse reactions with anti-rust pigments during the manufacturing and storage process, and the polymerization technology of cationic emulsifiers and active emulsifiers can solve this problem, making the quality and anti-corrosion performance of coating products more stable, and the formulation more flexible and changeable , the applicability is stronger

Abstract

The invention discloses a manufacturing method of cationic room-temperature crosslinking water-based vinylidene chloride metal anti-corrosion paint, which is characterized in that resin of the paint is cationic vinylidene chloride latex; an cationic emulsifier is polymerized with high pressure emulsions of a vinylidene chloride monomer and an acrylate monomer; an initiator is mixed by an oil-soluble initiator and a water-based initiator; the prepared vinylidene chloride latex is good in mechanical stability, and can be grinded together with a rust-resistant pigment; the cationic durability is good; cations dissociated from the rust-resistant pigment do not influence the storage stability of the water-based paint; and the anti-corrosion effect is excellent.

Description

technical field [0001] The invention relates to a method for manufacturing chlorine-biased latex, in particular to a method for manufacturing a cationic water-based chlorine-biased paint used for water-based metal anti-corrosion paints. 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, there are still many technical problems in the development and application of water-based coatings. The most critical technology lies in the development of high-performance water-based resin products. The function of the resin in the coating is to bond the pigments and fillers, and at the same time combine the substrate and the topcoat into a firm whole to prevent the erosion of anti-corrosion media. Generally speaking, the wet adhesion between the coating and the metal surface and the coating Water permeabi...
