Water-based ultraviolet curing coating

Abstract

The invention relates to water-based ultraviolet curing coating, containing water-based ultraviolet curing resin, a photo initiator, accessory ingredients and water; the water-based ultraviolet curingcoating is characterized in that: the water-based ultraviolet curing coating also comprises acrylic emulsion and corrosion inhibitors, all constituents are as follows by mass fraction: 15-45 percentof the water-based ultraviolet curing resin, 15-45 percent of the acrylic emulsion, 2-10 percent of photo initiators, 2-5 percent of the corrosion inhibitors, 0.2-1 percent of the accessory ingredients, and the balance of water; wherein the acrylic emulsion has the function of enhancing adhesive force, so as to greatly improve the adhesive force of the coating on a metal surface, be beneficial toimproving the anti-corrosion performance of coatings without needing reactive diluent to adjust the adhesive force of the coating and reduce the harm of the reactive diluent to environment and human body; wherein the defined amount of the corrosion inhibitors increases the anti-corrosion performance of the coating. The water-based ultraviolet curing coating is particularly suitable for protectivedecoration of the surfaces of metal bases,such as iron, aluminum, copper, nickel and the like, for a medium to long period.

Description

technical field [0001] The invention relates to a water-based ultraviolet light curing paint, which is especially suitable for medium and long-term protective decoration of metal surfaces. Background technique [0002] Metal anti-corrosion has always been a hot and difficult point in the field of metal anti-corrosion research. Although there were some measures to control corrosion in the past, metal corrosion still seriously troubled people. About 30% of the world's annual total steel is turned into useless scrap iron due to corrosion. The losses caused by corrosion all over the world are greater than the sum of losses caused by natural disasters such as volcanoes and earthquakes. At present, most of the anti-corrosion coatings developed and produced at home and abroad are solvent-based. Due to the volatility of solvents, they seriously damage the living environment to varying degrees. Therefore, reducing the solvent in anti-corrosion coatings has become an important resea...

However, although the diluent contained in this paint will not volatilize into the atmosphere and cause pollution, it is irritating to human skin and brings some inconvenience to use, and it can only play an initial protective effect on metals; ZL02138207. 7 Using maleic anhydride modified epoxy acrylate as active oligomer, adding adhesion promoting resin with epoxy groups, effectively improves the adhesion of the coating to metal, but still needs a certain amount in the formula the active diluent; CN1696226 disclosed water-based UV-curable coating, although the irritation of the diluent to the human body has been reduced, the water-based acrylic monomer used is still harmful to the human body, and is only applicable to flexible surfaces such as leather or artificial leather, and no corrosion protection
