Abstract
A zinc-rich water-based paint blends a binder and a chelating agent in a zinc slurry. The zinc slurry is blended in an amount of 61.7% by weigh. A potassium as the binder is blended in an amount of 30.0% by weight. A blending quantity of an ion exchange water is decreased as a blending quantity of EDTA-4K as the chelating agent is increased such as 0.2, 0.4, 0.7, 1.4 and 2.4% by weigh as, so that a total quantity becomes 100%.
Claims12
A zinc-rich water-based paint, containing a chelating agent added in a zinc-rich water-based paint that contains an alkali silicate and zinc powders,
- wherein an ethylene diamine tetraacetic acid (EDTA) or its salt is used as the chelating agent, and
- wherein the chelating agent is added in an amount of about 0.6% by weight or more to the zinc powders.
A zinc-rich water-based paint containing:
- a zinc slurry prepared by mixing zinc powders as a main component and an alkali silicate as an additive in an ion exchange water;
- a binder mixed in the zinc slurry and a chelating agent mixed in the zinc slurry so as to coordinate to zinc ions to form a stable chelate compound;
- wherein the chelating agent comprises a compound selected from a group consisting of an ethylene diamine tetraacetic acid (EDTA) and a salt of EDTA, and
- wherein the chelating agent is mixed in a proportion of about 0.6% by weight or more to the zinc powders.
A zinc-rich water-based paint, containing a chelating agent added in a zinc-rich water-based paint that contains an alkali silicate and zinc powders,
- wherein an ethylene diamine tetraacetic acid (EDTA) or its salt is used as the chelating agent, and
- wherein the chelating agent is added in an amount of about 1.4% by weight to the zinc powders.
