Preferably, the preservative is one or more of aluminum polyphosphate, aluminum zinc tripolyphosphate and zinc molybdate.
In order to achieve the aim of the invention, the invention also provides a preparation method of the environment-friendly inorganic static conductive anticorrosive paint, which comprises the following steps:
1) And (3) preparation of the component A: weighing silicate solution according to a proportion, putting the silicate solution into a stirrer, slowly pouring the methyl silicate solution into the silicate solution according to a weight proportion under a stirring condition, and continuously stirring for 10-20 min to obtain a component A;
2) And (2) preparing a component B: weighing spherical zinc powder, flaky zinc powder, ferrophosphorus powder, nano metal powder, metal fibers, conductive filler and preservative according to a proportion, putting into a dry powder grinding and dispersing machine, and grinding and dispersing for 20-40 min to obtain a component B;
3) Preparation of the coating: and (3) respectively weighing the component A and the component B according to a proportion, slowly adding the component B into the component A under the stirring condition to fully wet the component A and the component B, adding water accounting for 10-20% of the total amount of the coating, and uniformly stirring to obtain the environment-friendly inorganic static conductive anticorrosive coating.
Preferably, in the step 1), the rotation speed of the stirrer is adjusted to 500-1000 rpm; in the step 2), the rotation speed of the grinding and dispersing machine is adjusted to be 500-1000 rpm.
When the environment-friendly inorganic static-conducting anticorrosive paint is used, the environment-friendly inorganic static-conducting anticorrosive paint prepared by the invention is coated on the surface of metal to be coated by adopting a spraying or brushing process, and the environment-friendly inorganic static-conducting anticorrosive paint is obtained after the environment-friendly inorganic static-conducting anticorrosive paint is dried for 24 hours at room temperature.
The inorganic silicate is used as a film forming material, but not an organic film forming material, a film forming auxiliary agent and an auxiliary agent, so that the problem that formaldehyde and VOC are released from the paint is fundamentally solved, and the environment-friendly performance is excellent; in addition, after the silicate is modified by the methyl silicate, the water resistance and the corrosion resistance of the coating are improved due to the existence of the hydrophobic methyl.
In the invention, the spherical zinc powder improves the corrosion resistance of the coating due to the effect of the sacrificial anode in the corrosion resistance process of the coating; the flaky zinc powder is arranged parallel to the matrix in the coating, so that the corrosion resistance of the coating is improved.
The nano metal powder in the invention is used as rigid particles in the coating to disperse shrinkage stress when the coating is cured, so that the performances of cracking resistance and the like of the coating are improved, and meanwhile, the nano metal powder reacts with silicate to form aluminum silicate to strengthen the coating.
The superfine ferrophosphorus powder used as the cathode component partially replaces zinc powder, has an antirust effect on steel materials, reduces the consumption of the zinc powder, and further reduces the cost of the paint.
The metal fibers with a certain length form a mutually overlapped net structure in the coating, and the metal powder such as zinc powder in the coating and the conductive filler are mutually connected to form a conductive path, so that the static electricity conducting performance of the coating is obviously improved, and the strength of the coating is improved.
On one hand, the preservative is hydrolyzed to release phosphate radical or molybdate radical ions with strong complexing ability with iron ions to form a compact protective film on the surface of steel, so that the steel is prevented from further corrosion; on the other hand H generated by hydrolysis during the curing of the coating + The ions promote the solidification of the coating, strengthen the coating and improve the water resistance of the coating.
