Abstract

The invention relates to a method of preparing water resistant inorganic zinc-rich paint by adding a zirconium carbonate hardener. The paint is prepared by dropwise adding aluminum modified silicasolinto a low modulus potassium metasilicate solution to form a high modulus potassium metasilicate solution as an adhesive agent of the zinc-rich paint, adding a benzyltrimethylammonium hydroxide catalyst, dodecyl diol amide, isopropyl dioctyl tetra-oleophosphoric titanate and silicone acrylic emulsion to achieve uniform particle size distribution of the potassium metasilicate solution and no gelation reaction for a long time, and then adding the zirconium carbonate hardener to improve early water resistance of a paint film.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based inorganic zinc-rich coating and a preparation method thereof, belonging to the field of coating chemical industry. Background technique [0002] The annual economic loss caused by steel corrosion in the world accounts for about 2%-4% of the GDP of each country, and more than 100 million tons of metals are scrapped due to corrosion. Steel corrosion will significantly reduce the mechanical properties of steel metal materials such as strength, plasticity, and toughness. Destroy the geometric shape of metal components, increase the wear between parts, deteriorate the physical properties such as electricity and optics, shorten the service life of equipment, and even cause catastrophic accidents such as fire and explosion. [0003] Zinc-rich anti-corrosion coatings are widely used. Zinc-rich anti-corrosion coatings can not only isolate air, but also form primary battery protection. Zinc-rich...
