| 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, (CH3O)3Si(CH2)2Si(OCH3)3 and water; and the accelerator is dimethyl silicon oil water-based emulsion and/or polyether modified polysiloxane. 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. |
