Abstract

The invention discloses a water-based silicone-acrylic mica iron oxide anti-corrosion coating. The anti-corrosion coating is prepared from the following raw materials in parts by weight: 30-50 parts of silicone-acrylic base material, 20-41 parts of pigment, 1-10 parts of auxiliary pigment, 4-15 parts of filler, 5-20 parts of water and 1-20 parts of assistant, wherein the pigment is micaceous iron oxide gray; the auxiliary pigment is at least one of rutile titanium dioxide, nano-titanium dioxide, phthalocyanine pigment, compound pigment and iron oxide pigment; the weight ratio of the auxiliary pigment to the pigment is (1-10):(20-41); the silicone-acrylic base material is water-based silicone-acrylic emulsion, a mixture of water-based silicone-acrylic emulsion and water-based pure silicone-acrylic emulsion or a mixture of water-based silicone-acrylic emulsion and water-based styrene-acrylic emulsion. By adopting the coating, not only is the water, acid and saline resistance increased, but also the corrosion resistance is excellent.

Description

technical field [0001] The invention relates to a medium coating for zinc-rich anticorrosive coatings such as water-based inorganic zinc-rich primer or water-based epoxy zinc-rich primer, in particular to a water-based silicon-acrylic acid anti-corrosion coating, which is suitable for improving the water resistance, acid resistance and corrosion resistance of the coating. Salt water resistance. Background technique [0002] Corrosion of steel structures has spread to all fields of the national economy and brought huge losses to the national economy. Coating anti-corrosion coating on the surface of the steel structure to isolate the corrosive medium from the steel structure matrix is ​​one of the most effective and commonly used methods for steel structure anti-corrosion. Zinc-rich anti-corrosion coatings such as water-based inorganic zinc-rich coatings or water-based epoxy zinc-rich coatings are used for steel structure anti-corrosion, and the anti-corrosion effect is good;...
