Fig. 1 is the tissue for the composite coating that 1 floating coat composite material of Application Example obtains.It can be seen that even tissue causes
It is close.
A coating composite material of the invention has good anti-corrosion capability, while with good stability and practicability,
It can be widely applied to steel field etc..Preparation method of the present invention is simpler, and production cost is low, is suitable for industrialized production.Coating
Composite material contains composite ceramic, has good wearability, therefore ensure that the hardness of coating.Meanwhile composite ceramic
Itself has good corrosion resistance again.Ceramics process is rare earth modified, reduces the brittleness of material.Make zinc powder, two kinds of alloyed powders, answer
It closes ceramic powder to be uniformly distributed in the solution, improves the density of coating, also extend the salt-fog resistant time of coating.Zinc in coating
Powder, alloyed powder, composite ceramic are overlapped mutually composition coating, make to corrode route then tortuous extension, improve material corrosion resistance.
There are the second-class three kinds of alloys of zinc powder, alloyed powder one, alloyed powder, especially alloyed powder one, alloyed powder two by adding rare earth in coating,
Not only make coating that there are more metal protection abilities, protective capability is reinforced, while also improving the electric conductivity of coating.It is added in coating
Ethyl polyoxyethylene ether, nonylphenol polyoxyethylene ether etc., improve the bond strength of material, therefore also improve the anti-corrosion of coating
Property.
