Abstract

The invention provides a metal protecting coating. The metal protecting coating is obtained after mixing a raw material mixture uniformly, wherein the raw material mixture contains water soluble silicate, an accelerant, a silane coupling agent, a silicon oxide filler, water soluble film-forming resin and water; the accelerant is water-based emulsion of polyethylene wax and/or water-based emulsion of oxidized polyethylene wax; the silane coupling agent contains first silane derivatives shown in a formula (1) in the specification; and in the formula (1), R1, R2 and R3 are respectively methoxy or ethoxy, and n is an integer from 1 to 4. The invention also provides a hot-dipped metal material. The hot-dipped metal material comprises a hot-dipped metal substrate and a coating attached to the hot-dipped metal substrate, wherein the coating is a cured product of the metal protecting coating. Protective films formed by the metal protecting coating provided by the invention have excellent corrosion resistance, water resistance, heat resistance, fingerprint resistance and lubricating property.

Description

technical field [0001] The invention relates to the field of metal protection, in particular to a metal protection coating and a hot-dip metal material. Background technique [0002] Hot-dip metal materials, including hot-dip galvanized metal materials and hot-dip galvanized metal materials, in order to prevent corrosion, a layer of metal protective paint will be coated on the surface of the hot-dip metal materials to form a protective film. Therefore, the performance of metal protective coatings is very important for the anti-corrosion of hot-dip metal materials. [0003] For example, CN101608306A discloses a passivation solution, which also belongs to a metal protective coating, and is characterized in that the passivation solution is an aqueous solution containing a water-soluble molybdenum compound, boric acid, water-soluble organic matter and silica sol, wherein the water-soluble The organic compound is a mixture of alcohol and organic carboxylic acid.
