The invention relates to stone-
crash-resistant automobile
corrosion-resistant
wax and a preparation method thereof, and belongs to the technical field of
metal corrosion prevention. The characteristicthat environment-friendly
phytic acid compounds
inositol hexaphosphoric acid and
tannic acid are liable to be self-assembled on the surface of
metal to form a film is utilized; when the environment-friendly
phytic acid compounds
inositol hexaphosphoric acid and
tannic acid are contacted with the surface of the
metal, the two anti-
rust groups are chelated with the surface of the metal to generateone layer of compact
passivation film, and composite paraffin is met and guided to gradually form a protective
wax film on the surface of plate material; on the other hand, the two anti-
rust groups have optimal compatibility with metal polymers with excellent
corrosion resistance such as
titanium and aluminum in the metal, the two anti-
rust group and a film-forming substance jointly form a corrosion-resistant layer with high compactness on the surface of the metal, and the corrosion-resistant layer has extremely high barrier property on
erosion and corrosion mediums such as water,
oxygen and ions. The corrosion-resistant
wax prepared by the method has extremely high barrier property and high stone
crash resistance, is applied to the surface and the hole gap of the material by a spray-
coating mode, and has high long-time corrosion resistance.
