Abstract

The invention provides a metal protective paint which is prepared by uniformly mixing a raw material mixture, wherein the raw material mixture contains water-soluble silicate, silicon oxide filler, accelerator, water-soluble film-forming resin, thiopropyl silane coupling agent and water; and the accelerator is polyethylene wax water-based emulsion and / or oxidized polyethylene wax water-based emulsion. The invention also discloses application of the metal protective paint in preparation of metal materials. The invention also provides a hot-dip metal material which comprises a hot-dip metal substrate and a coating attached to the hot-dip metal substrate, wherein the coating is the cured product of the metal protective paint. The protective film formed by the metal protective paint provided by the invention has very excellent corrosion resistance, water resistance, heat resistance and fingerprint resistance.

Description

technical field [0001] The invention relates to the field of metal protection, in particular to a metal protection coating, the application of the 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 alco...
