Description

Band rust band wet coating dress anticorrosive coating
Technical field
The present invention relates to a kind of coating, be specifically related to a kind of band rust band wet coating dress anticorrosive coating.
Background technology
Corrosion is arch enemy of man, and silver corrodes and causes the loss of iron and steel to account for national economy total output value and be up to 4%, is institute There are six times of the loss summation that natural disaster caused.
Tackling the most economical maximally effective means of corrosion is to use anticorrosive coating, and etching ground consumption is big, is coatings industry The kind of middle ranking second.The total amount of the anticorrosive coating that China uses for anticorrosion every year is more than million tons.
But before anticorrosive coating is to coating metal surfaces such as iron and steel, it is necessary to the corrosion of metal surface is removed, Er Qieyou A little environment also need to the moisture of steel surface to remove.Such as the application of oceanic tectonic thing, its surface processes and is extremely difficult to attain U.S.;Again Such as ballast tank, cabin is narrow and small, and cabin is narrow and small, the most pleasant suitably operates in cabin.Under these situations, iron and steel table The surface difficult treatment in face is the biggest.This not only to spend a large amount of manpower and materials, and surface is also difficult to clean out.In a word with Corrosion or moisture are difficult to Ex-all.State
There is the anticorrosive coating of low prepared surface in although, but should deposit at surface moisture again in the case of having corrosion Carrying out steel surface anticorrosion under, this is that suggestion is highly difficult and be difficult to the thing proved effective really.
Summary of the invention
It is an object of the invention to, it is provided that a kind of band rust band wet coating dress anticorrosive coating, to overcome prior art to be deposited Disadvantages mentioned above and deficiency.
The present invention provides one can reduce rust cleaning work, can be coated with again protection and make on the iron and steel with moisture of the surface Epoxy anticorrosion coating, so that solve at present can not application asking of carrying out protecting with rust and moisture on steel surface Topic.
For realizing this purpose, the two component epoxy anticorrosive coating that the present invention uses turns added with rust on its first component The component of agent, is to be made up of phosphoric acid, potassium ferrocyanide, tannic acid and butanol, and the rust of steel surface can be carried out molten by it Solving and react, generation does not harms iron and steel surface compact coating thus plays the changing effect to rust.It is transformant, stable type The multi-functional rust transforming agent being integrated in one with certain permeability.
In the two component epoxy anticorrosive coating that the present invention uses, its component B is to use modified by cardanol phenolic aldehyde amine Firming agent, the main source of this firming agent is the garbage Fructus anacardii shell of regenerative Fructus anacardii, thus carries out reaction with phenolic aldehyde amine and obtains. This firming agent is manufactured by Shanghai Jingtian New Materials Technology Co., Ltd., and it can be on surface with the anticorrosive coating that epoxy resin forms Process less demanding, and application can be carried out on moist surface and generate iron and steel is had excellent antisepsis coating.
Thus can solve coating in band rust and the difficult problem with wet steel surface application.
Solve the technical problem that required for the present invention, can be achieved through the following technical solutions:
As a first aspect of the present invention, a kind of band rust band wet coating dress anticorrosive coating, it is characterised in that according to weight Number meter, has a following component:
First component:
Resin: bisphenol A epoxide resin E20;
Color stuffing: titanium dioxide, zinc oxide, zinc phosphate, calcium phosphate, aluminium triphosphate, barium sulfate;
Rust transforming agent: phosphoric acid, potassium ferrocyanide, tannic acid, butanol;
Mixed solvent: methylisobutylketone, dimethylbenzene, butanol;
Auxiliary agent: anti-settling agent, levelling agent, dispersant;
Component B:
Modified by cardanol phenolic aldehyde amine;
Mixed solvent: methylisobutylketone, dimethylbenzene, butanol.
According to ratio of weight and number meter, first component: component B mixes before using with 90~100:1~1.2().
In first component, resin: color stuffing: rust transforming agent: mixed solvent (ratio of weight and number)=25~28:33~36:3.5 ~30~35:0.5~1.5.
In component B, modified by cardanol phenolic aldehyde amine: mixed solvent (ratio of weight and number)=75~80:20~25.
In first component, the ratio of components (ratio of weight and number) of color stuffing: titanium dioxide: zinc oxide: zinc phosphate: calcium phosphate: three Poly aluminium phosphate: barium sulfate=30~32:20~25:8~11:8~11:8~11:9~12.
In first component, the ratio of components (ratio of weight and number) of rust transforming agent: phosphoric acid: potassium ferrocyanide: tannic acid: butanol= 76~90:5~12:3~8:2~6.
In first component, the ratio of components (ratio of weight and number) of mixed solvent: methylisobutylketone: dimethylbenzene: butanol=35~ 40:55~60:5~8.
In component B, the ratio of components (ratio of weight and number) of mixed solvent: methylisobutylketone: dimethylbenzene: butanol=35~ 40:55~60:5~8.
As a second aspect of the present invention, the preparation method of a kind of band rust band wet coating dress anticorrosive coating, its feature exists In, comprise the following steps:
(1) resin, part of auxiliary and partial solvent are stirred, then by whole color stuffings and rust transforming agent, remaining Auxiliary agent and remaining solvent are poured into;
(2) stirring in high speed dispersor, put into sand mill and carry out sand milling after stirring evenly, reach fineness 40 μm, first component fills Bottle;
(3) firming agent is fully mixed by component B before the use with solvent.
As a third aspect of the present invention, the application of a kind of band rust band wet coating dress anticorrosive coating, it is characterised in that be coated with Before dress, first component is sufficiently mixed with the ratio of 90~100:1~1.2 with component B, treats application.
Further, described application uses brushing, spraying and the mode of roller coat.
Beneficial effects of the present invention:
The coating of the present invention, technical ability carries out application in the presence of band corrosion situation surface moisture again and rises steel surface To good protective effect.This has filled up blank for domestic anticorrosive coating undoubtedly.
In the two component epoxy anticorrosive coating of the present invention, the epoxy resin used is bisphenol A type epoxy resin E20.This resin relative molecular weight is low, and after solidification, crosslink density is high, and the coating of formation is fine and close, and hardness of paint film is high, solvent resistance, resistance to Chemicals etc. are strong.The color stuffing used does not contains heavy metal, including titanium dioxide, zinc oxide, zinc phosphate, calcium phosphate, trimerization phosphorus Acid aluminum and barium sulfate, they or strong covering power, or can play steel surface chemical physical action is protected iron and steel, or Economic consideration of going out uses inert filler etc..Adjuvant used for anti-settling agent, levelling agent and dispersant etc., it is to make coating It is smooth and set that system each component is distributed homogeneous, coating surface up and down.
