Abstract
The invention provides a self-cleaning water-based nano coating and a preparation method thereof. The self-cleaning water-based nano coating is prepared from the following raw materials: water-based polyurethane acrylic emulsion, polyamide-imide resin, modified epoxy resin, diatomite, a catalyst, a coupling agent, a curing agent, a defoaming agent, a rheological agent, a dispersing agent and an anti-corrosion additive. The self-cleaning water-based nano coating with high overall stability and remarkable corrosion resistance can be obtained by optimizing formula components, the coupling agent is prepared by compounding tridecafluorooctyltriethoxysilane, toluene diisocynate, isophorone diisocyanate and isopropyl alcohol, the water resistance and pollution resistance of a coating can be promoted, and the self-cleaning water-based nano coating has the advantages that the self-cleaning water-based nano coating is high in overall stability and remarkable in corrosion resistance; coco fatty acid diethanol amide and 3-propanediol in the anti-corrosion additive are combined for use, the dispersing agent is prepared from zinc oxide, silicon dioxide, bis (hydroxymethyl) propionic acid and calcium carbonate, and then the dispersing agent, the coupling agent and the anti-corrosion additive have a synergistic effect, so that the anti-corrosion and water-resistant effects of the coating are further improved.
Description
technical field [0001] The invention relates to the field of paint preparation, in particular to a self-cleaning water-based nano paint and a preparation method thereof. Background technique [0002] Nano-coatings have a wide range of uses, such as public facilities, household appliances, ships, military and chemical anti-corrosion and other fields. In recent years, with the promulgation of some green environmental protection policies, water-based nano-coatings have attracted more and more attention from researchers and enterprises. Although there are many water-based nano-coatings on the market and have been industrialized, there are still the following problems: the surface tension of water-based nano-coatings is high, and the pigments and fillers cannot be fully dispersed, and water molecules are easy to enter the interior of the matrix and cause corrosion. During the process, the highly hydrophilic coating is easily polluted, which leads to the performance of the water-...
