In the present invention, the expanded perlite is organic expander perlite.
In the present invention, the organic solvent is benzene kind solvent.
In the present invention, described organic solvent is benzene, toluene or dimethylbenzene, or its mixture, preferably dimethylbenzene.
In the present invention, it is 3 in mass ratio by Mo powders, ZrC powders that the Mn-ZrC composite granules, which are,:(1~2) passes through machine
The realization of tool ball-milling method is uniformly mixed and prepared, wherein, the particle diameter of the Mo powders is 50~100 μm, and purity is more than
95wt%；The particle diameter of ZrC powders is 10~100 μm, and purity is more than 95wt%.
Yittrium oxide particle diameter very little, superficial attractive forces are strong, and surface can be big, chemical purity height, good dispersive property, thermal resistance, resistance
In terms of there is special performance, and with superior stability, reinforcing, thickening property and thixotropy.Yittrium oxide has three
Network structure is tieed up, possesses huge specific surface area, shows great activity, network structure can be formed when coating is dried, together
When add the intensity and finish of coating, and improve the suspension of pigment, the color of coating can be kept not fade for a long time.
Scattered, the electro-wetting principle of dispersant in anticorrosive paint, one be dispersant adsorption in powder particles, by the powder of cohesion
Particle is moistened；Two be that macromolecule dispersing agent is adsorbed on powder particles surface, increase pigment and the interparticle surface charge of inserts,
Interparticle electrostatic repulsion is improved, and effectively increases interparticle steric hindrance, makes stable scattered of powder particles in liquid
It is possibly realized.Divided according to molecular structure, dispersant is generally divided into two major classes：Inorganic dispersant and organic dispersing agent.Inorganic point
It is in the majority with polyphosphoric acid salt in powder, such as calgon, PTPP, sodium polyphosphate and tetrapotassium pyrophosphate.It is acted on
Mechanism be by hydrogen bond and chemisorbed, rise electrostatic repulsion stabilization.Its advantage is scattered to inorganic pigment and inserts
Effect is good, but with the rise of pH value and temperature, polyphosphate is easily hydrolyzed, not good to extended storage stability.It is organic scattered
Agent includes polyacrylate, polyamine/maleic acid salt, polyisobutene/maleic acid salt etc..Their the characteristics of
It is strong absorption or anchorage effect to be produced on powder surface, with longer strand to form steric hindrance, the end of the chain has water-soluble
Property, the also auxiliary result for having electrostatic repulsion, reaching stabilization having.
Organic dispersing agent is different because of its molecular weight, and performance can be different；Low-molecular-weight type dispersant has one or many
The individual polar group being spatially close, they are adsorbed in surface of pigments, and stabilizing powder particle is carried out with spatial masking effect, so that
Decline viscosity, this kind of dispersant is mainly used in inorganic pigment, because inorganic pigment is ionic structure, there is higher surface pole
Property, dispersant is easy to absorption.And organic pigment is because of its surface group containing C, H, O, no ion activity, so often using HMW
Dispersant, there is the more group that sticks to adsorb on the surface of organic pigment, it can form lasting suction on organic pigment
Attached layer.But the molecular weight of dispersant too great Yi flocculates.So should be according to pigment and inserts type during the type of selection dispersant
And select.Dispersant used in the present invention can be organic dispersing agent, preferably acrylic copolymer solution, further preferably
For BYK2020 dispersant.
Molybdenum disulfide micro mist is added in the present invention can assign anticorrosive paint certain thixotropy and structural viscosity, play thickening anti-
Heavy effect.Organic solvent used mainly plays diluting effect in the present invention, with adjusting coating viscosity.
The anticorrosive paint that the present invention is provided, can also include coating in conven-tional adjuvants, such as pigment, thickener, preservative,
Mixture more than one or both of defoamer etc..
The addition of conven-tional adjuvants can make it that obtained anticorrosive paint performance is more outstanding.It is pre- that pigment can have coating
Fixed color and luster, pigment of the invention is preferably free of the anti-corrosion paint of heavy metal, such as red lead, zinc yellow, trbasic zinc phosphate, strontium chromate and molybdic acid
Zinc.Thickener can cause coating to have preferable thixotropy, and the present invention selects nonionic polyurethane class compound.Preservative
The fungus growth in coating can be suppressed, coating is kept steady quality.Preservative of the present invention is preferably OIT.Froth breaking
Agent can suppress foam, make to be not likely to produce shrinkage cavity and flake during coating application, and defoamer of the invention can use hydrophobic titanium dioxide
The mixture of silicon and mineral oil.The addition of conven-tional adjuvants can be added according to the general knowledge of those skilled in the art.
Present invention also offers the preparation method of foregoing anticorrosive paint, comprise the following steps：
First Polybenzoxazine, polyamine, o-dihydroxy aromatised fraction and dispersant are mixed, then by obtained mixture
Enter with yittrium oxide, Brazil wax, talcum powder, Mn-ZrC composite granules, expanded perlite, molybdenum disulfide micro mist and organic solvent
Row mixing, so as to obtain the coating.
Anticorrosive paint provided by the present invention can be also made by other conventional preparation methods, and the present invention does not do special limit
It is fixed.
Compared with prior art, the present invention at least has the advantages that：
The anticorrosive paint that the present invention is provided has excellent mechanical property, when sea water resistance is washed away, sea ice is collided, ship is stopped
Wear resistance it is strong, and with excellent decay resistance, salt-fog resistant time is more than 4200 hours, and the wet-heat resisting time is more than
4200 hours, and with excellent mechanical property.
