Description
Technical field
The present invention relates to a kind of environmentally friendly anticorrosive paint and preparation method, belong to anticorrosive coating field.
Background technology
Metal erosion is a kind of very universal phenomenon, and it is seldom because simple machinery or physical factor are drawn to corrode
Rise, most damage all has close relationship with its surrounding enviroment.Corrosion of metal is present in national economy and national defence is built
If every field, not only the facility in national economy and national defense construction is caused greatly to damage, but also in metal erosion
Stress corrosion and corrosion fatigue caused by accident can endanger personal safety.Metal erosion causes substantial amounts of energy resources wave
Take and environmental pollution.
To metal protect most practical, economic, effective method using coating.Therefore the research one to anticorrosive paint
It is directly the important topic of metal coating and coating industry.Traditional anticorrosive metal paint is almost solvent based coating, into
Volatilize in membrane process with substantial amounts of solvent.The solvent of volatilization not only damages to the environment of human body and periphery and dirt
Dye, while also result in the waste of resource.And the rust resisting pigment added in traditional anticorrosive paint is all harmful containing lead, chromium etc.
Material, equally damages human body and environment.With the continuous improvement to environmental requirement, environmental consciousness it is continuous strengthen and
The stringent control of laws and regulations environmental pollution, there is an urgent need to environmentally friendly coating at present.Therefore to the anti-corrosion of environment-friendly type
The cry of coating is increasingly apparent.
To reduce the pollution to environment, the research to environment-friendly type coating at present concentrates on water paint and low solvent-borne type applies
Material.Epoxy coating is the environment-friendly type coating of current application prospect maximum.Except coating in itself, the selection of rust resisting pigment and make
With a very important factor for being also decision coating property quality.In order to substitute the poisonous pigment such as traditional chrome yellow, red lead,
People have studied such as trbasic zinc phosphate, aluminium triphosphate, and the rust resisting pigment of scale class, such as Chinese patent literature CN102382494A
（Application number：201110226841.0）Disclosed glass flake anticorrosion paint, but these rust resisting pigments disperse there are of high cost
Property is bad, than it is great the shortcomings of.Polyaniline has very excellent performance, such as Chinese patent literature in anticorrosive paint
CN102634276A（Application number：201210125211.9）Disclosed a kind of polyaniline anti-corrosive paint and preparation method thereof, this is anti-
Rotten coating has used polyaniline-modified montmorillonite Composite filler, play good anti-corrosion effect, but montmorillonite is in itself
Anti-corrosion effect is simultaneously bad, and modifying process is cumbersome.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of environmentally friendly anticorrosive paint and preparation method.The present invention's is anti-
Rotten coating, easily dry, safety and environmental protection, unharmful substance, corrosion resistance is strong, strong acid-base resistance, non-aging peeling, has excellent
Adhesive force, pliability is good, hardness is high.The preparation method of the anticorrosive paint is simple, cost is low, can produce and apply at normal temperatures and pressures
Cover, paint film physical property and excellent anti-corrosion performance after curing, asepsis environment-protecting, paint stability is high.
Technical scheme is as follows：
A kind of modified environment-friendly anticorrosive paint, the raw material which includes following mass percent form：
Epoxy resin latex 30%-60%, curing agent 5-10%, polyaniline-modified FeOCl 5-15%, aluminium triphosphate 5-
10%, trbasic zinc phosphate 2-5%, iron oxide red 2-8%, titanium dioxide 1-5%, mica powder 1-5%, Meteorological Act white carbon 0.1%-2%, silane are even
Join agent 0.1%-2%, defoamer 0.1%-3%, anti-settling agent 1%-3%, anti-flash rusting agent 0.1%-5%.
, according to the invention it is preferred to, the polyaniline-modified FeOCl is made as follows：
（i）FeOCl is dried, grind after be distributed in aniline, ultrasonic disperse 10-30min, under lucifuge, nitrogen environment
1-7d is stirred, the 60-90 DEG C of drying under nitrogen protection of filtering obtained solid, grinds to obtain FeOCl-An composite powders；
（ii）FeOCl-An composite powders are dispersed in water, ultrasonic disperse 10-30min, then stirs 1-4h；
（iii）By step（ii）Gained system is slowly added dropwise under agitation（0.1-1）The ammonium persulfate solution of mol/L, so
After continue stir 4-12h, ammonium persulfate：The mass ratio of FeOCl-An is 1:（10-20）；Solid is obtained by filtration, is dried at 60-90 DEG C
It is dry, grinding, up to polyaniline-modified FeOCl.
, according to the invention it is preferred to, the epoxy resin latex is MU-601 epoxy resin latexes.
, according to the invention it is preferred to, the silane coupling agent be one kind in KH550, KH560, KH602, KH792 or
Two or more mixing.
, according to the invention it is preferred to, the anti-flash rusting agent is the anti-flash rusting agent of CH07A.
, according to the invention it is preferred to, the anti-settling agent is inorganic gel anti-settling agent.
, according to the invention it is preferred to, the curing agent is water-soluble triethylene tetramine.
According to the present invention, the preparation method of above-mentioned environmentally friendly anticorrosive paint, including step are as follows：
（1）FeOCl powder is distributed in aniline, ultrasonic disperse 10-30min, 1- is stirred under lucifuge, nitrogen environment
