Embodiment 1

[0012] 1. Preparation of modified nano-zirconia

[0013] And the modified nano zirconium dioxide is prepared by the following method: Weigh 10g of zirconium carbonate, add excess sulfuric acid and stir to obtain zirconium sulfate; prepare 1N ammonium bicarbonate solution, add dropwise to zirconium sulfate at a speed of 10-15ml / min solution; keep stirring until the precipitation is complete, after standing still, filter with suction, wash, then extract with absolute ethanol, dry the obtained solid, then burn at a high temperature above 350°C, cool and grind, after measurement, more than 90% The particle size of the particles is less than 100nm to obtain nano zirconium dioxide; put 10g of the above-prepared nano zirconium dioxide in 300mL of absolute ethanol, stir and reflux for 30min, stop the reflux, keep the temperature at 70°C, add stearic acid, and continue stirring 1h, cooling, filtering and drying to obtain modified nano zirconia.

Abstract

The invention provides an anticorrosive nanometer aqueous architectural coating which is prepared by using modified nano-scale pigment (particularly modified nano-zirconia) as a basis and then mixing with other nonpoisonous materials, has good anticorrosive effect, particularly resists ultraviolet rays, does not contain solvents, is nonpoisonous and environment-friendly and is particularly applicable for the anticorrosion of metals, particularly, outdoor metal components.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof. Specifically, the present invention relates to a nanometer water-based architectural coating for preventing metal corrosion and a preparation method thereof. Background technique [0002] Metal corrosion has brought huge losses to the national economy. In my country, the economic loss caused by metal corrosion is as high as 30 billion yuan, accounting for 4% of the gross national product. Various techniques have been used to protect metals from corrosion for a long time. One of the most effective and commonly used methods for metal equipment is to coat the metal surface with a protective coating to isolate the contact between the corrosive medium and the metal substrate. At present, the anti-corrosion coatings coated on metal surfaces are usually solvent-based coatings. Although they have an effect of inhibiting corrosion, they pose an environmental pollution problem because they ...
