Technical Field

The invention relates to the field of metal coating materials, in particular to a metal coating with an anti-corrosion effect.

Background

The metal material is applied to various fields, plays an unfortunate role in the advancement and development of science and technology, is easy to corrode, and has poor anticorrosive effect in the conventional anticorrosive paint for the metal material, so that the metal paint with the anticorrosive effect is urgently needed to be designed.

disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a metal coating with an anti-corrosion effect, and solves the problem that the existing metal coating is poor in anti-corrosion effect.

(II) technical scheme

in order to achieve the purpose, the invention provides the following technical scheme: the metal coating with the anti-corrosion effect comprises the following raw materials in parts by weight:

Epoxy resin: 15-20 parts of a solvent;

30-35 parts of cellulose ester;

Silicon dioxide emulsion: 15-20 parts of a solvent;

titanium dioxide: 7-11 parts;

Calcium carbonate: 2-4 parts;

talc powder: 5-8 parts;

Defoaming agent: 10-15 parts;

0.3-0.6 part of a leveling agent;

wetting agent: 2-4 parts;

toluene: 20-30 parts of a solvent;

An amphoteric compound: 5-10 parts;

chromate: 4-8 parts.

preferably, the cellulose ester is nitrocellulose.

Preferably, the defoamer is polydimethylsiloxane.

preferably, the leveling agent is an alkyl modified organosiloxane.

Preferably, the wetting agent is alkyl polyoxyethylene ether.

Preferably, the amphoteric compound is aluminum hydroxide, barium hydroxide and zinc oxide, and the ratio of 3: 1: 0.5 is mixed.

(III) advantageous effects

The invention provides a metal coating with an anti-corrosion effect, which has the following beneficial effects:

(1) In the present invention, chromate is added to react moisture and oxygen with each other when passing through the anticorrosive paint to form anticorrosive ions, thereby passivating the surface of metal such as steel and preventing the metal ions from dissolving out to achieve the purpose of corrosion prevention.

(2) According to the invention, aluminum hydroxide, barium hydroxide and zinc oxide are added, so that the corrosion prevention effect is realized by easily performing a chemical action with acid and alkali harmful substances, and meanwhile, the aluminum hydroxide has a certain flame retardant effect, thereby being beneficial to protecting metal materials and realizing the purpose of fire prevention.
