Abstract

The invention provides outdoor type water-based corrosion-resistant finish paint and a preparation method thereof, and relates to the field of coating. The outdoor type water-based corrosion-resistantfinish paint comprises a component A and a component B, wherein the component A comprises polyvinyl alcohol, water-based acrylic resin, water-based epoxy resin and distilled water; and the componentB comprises polyimide with low molecular weight, a water-based polyurethane curing agent, a dispersing agent sodium dodecyl benzene sulfonate, a mildewproof agent dodecyl dimethyl benzyl ammonium bromide, a flatting agent organic modified polydimethylsiloxane, a defoaming agent water-based polysiloxane, a flame retardant ammonium polyphosphate, an ultraviolet light absorbent nanometer cerium dioxide, pigment and distilled water. The outdoor type water-based corrosion-resistant finish paint provided by the invention has the advantages of high brightness, high weather resistance, water tolerance, alkali tolerance, ultraviolet radiation resistance and the like, and is widely applied to corrosion-preventing and decoration industries of outdoor articles.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an outdoor water-based anti-corrosion finish paint and a preparation method thereof. Background technique [0002] Water-based anti-corrosion topcoat is an environmentally friendly coating that uses water as a diluent without adding organic solvents. It does not contain toxic solvents, so the water-based anti-corrosion topcoat is non-toxic, has no irritating odor, is harmless to the human body, and will not pollute Surroundings. In real life, most ships, outdoor power facilities, steel bridges and other mechanical equipment are often damaged by sun and rain corrosion, so spray paint is usually used for protection. The top coat is the last layer of paint in the entire coating, which plays a major decorative and protective role throughout the coating and determines the durability of the coating. [0003] First of all, weather resistance is an important indicator of the topcoat. It is requ...
