Description
Technical field
The present invention relates to anticorrosion coating material technical fields, more specifically, it relates to a kind of ceramic filler epoxy zinc-rich
Anticorrosion coating material and preparation method thereof.
Background technique
Metal erosion is a spontaneous process, all brings serious loss to the production and living of the mankind all the time, very
To being catastrophic accident.Corrosion is actually to the havoc of natural resources earth polar and waste, and the breakage or fracture of metal are not only
It may cause the leakage of harmful substance, while also resulting in the pollution of environment.In addition, if being corroded in a certain key position
Situation is destroyed, and does not obtain timely concern processing, the catastrophic failure of burst may be caused, jeopardize the peace of daily life
Entirely, greatly loss and harm, this point is brought to embody in metal anti-seismic material especially vivid to national economy.
Metal anti-seismic material in the world, such as para-seismic support, antidetonation hanger fail in antidetonation very crucial one because
Element is exactly to receive corrosion, according to incompletely statistics, in the world the every annual meeting of metal para-seismic support because caused by corrosion 2,000,000,000 loss.With
Metal erosion protection project conduct a research, the research applied to the anti-corrosion material in para-seismic support is also of concern, mesh
Before generally believe organic coating be it is most effective, most economical, using most common anti-corrosion measure.
However, coating is not a perfect physical barriers layer, although because coating organic coating energy in metal surface
Enough delay diffusion of the corrosive media to metallic matrix, but cannot completely inhibit.Once corrosive media reaches gold through coating
Metal surface, then the corrosion of metallic matrix is still inevitable.Therefore, it is necessary to be modified to coated substrate, to ensure
Corrosion-inhibiting coating can effectively keep apart corrosive media and metallic matrix during use.But what general material was prepared into
Often there are biggish gaps for coating and metallic matrix, do not have good physical shielding and act on, are easy to cause corrosive medium
Metallic matrix is entered, to cause corrosion failure.
Epoxy zinc-rich coating material is a kind of anticorrosion coat material of excellent anti-corrosion performance, is widely used in metal
Heavy antisepsis field.Zinc is sacrificing positive pole in epoxy zinc-enriched paint, and the content in coating is typically larger than 70%, however, due to
Zinc content is excessively high in coating, coating be easy it is porous, adhesive force decline, and zinc-rich coating generated when playing cathodic protection compared with
More zinc salts influences the binding force between upper coating and zinc-rich coating, reduces so as to cause the antiseptic property of coating.
Summary of the invention
The first object of the present invention is to provide a kind of epoxy zinc-rich anticorrosion coating material that ceramic filler is modified, gained anti-corrosion
Coating material coating adhesion is good, antiseptic property is good.
To achieve the above object, it is realized by following technological means: a kind of ceramic filler epoxy zinc-rich anticorrosion coating material,
Group including following parts by weight is grouped as:
The modified epoxy is orthophthalic modified epoxy resin.
Advanced optimize are as follows: the ZnO conductivity ceramics powder the preparation method comprises the following steps: by analytically pure ZnO, Al2O3、TiO2、
MgO is 1:0.3:(0.1-1 according to mass ratio): after (0.1-0.8) proportion ingredient, appropriate distilled water and poly amic acid is added to disperse
Agent ball mill grinding 2h adds appropriate PVA solution and is granulated, is then pressed into green compact, green compact dumping is placed in air 1250 DEG C
2h is sintered up to ZnO conductivity ceramics, is finally 20 μm of ceramic powders below by the broken partial size of wearing into of ceramics.
It advanced optimizes are as follows: the epoxy resin of the orthophthalic modified epoxy resin is epoxy resin SM6101.
It advanced optimizes are as follows: the complexing agent is one or more of EDTA, CDTA, NTA, EGTA.
It advanced optimizes are as follows: the auxiliary agent is the dispersing agent for including 0.5-1 parts, 0.2-0.5 parts of defoaming agent, 0.3-0.5
The levelling agent of part, the dispersing agent are one of BYK191, BYK190, BYK180 or BYK110 or a variety of, the defoaming
Agent be one of polypropylene glycerol aether and polyoxyethylene polyoxypropylene glycerin ether, dimethyl silicone polymer or a variety of, it is described
Levelling agent is one of polyacrylic acid, carboxymethyl cellulose and butyl cellulose or a variety of.
It advanced optimizes are as follows: the modified amine curing agent is 60-80wt%, active hydrogen equivalent weight 300- to consolidate part
350 polyamide-based curing agent.
It advanced optimizes are as follows: the organic solvent is one in ethylene glycol ethyl ether, butyl glycol ether or dipropylene
Kind is a variety of.
The second object of the present invention is to provide the epoxy zinc-rich that the ceramic filler that a kind of adhesive force is good, antiseptic property is good is modified
The preparation method of anticorrosion coating material.
Described method includes following steps:
(1) raw material is weighed according to each group distribution ratio；
(2) weighed ZnO conductivity ceramics powder and complexing agent, a part of solvent are added in reaction kettle, are heated to 70-
It is 90 DEG C, cooling after persistently stirring insulation reaction 5-8 hours；
(3) weighed modified amine curing agent, auxiliary agent and another part solvent are mixed and stirred for uniformly, then successively added
Enter zinc powder, modified epoxy and step (2) resulting slurries, high-speed stirred is dispersed more than half an hour, and viscosity is adjusted, and is made
Ceramic filler epoxy zinc-rich anticorrosion coating material.
The present invention having the beneficial effect that compared with prior art
(1) ZnO ceramic powder electric conductivity is good, and the usage amount of zinc powder in coating can be greatly reduced, as zinc content can be down to
50% hereinafter, far below 70% in usual content；
(2) synergistic effect of ZnO conductivity ceramics powder and zinc powder, plays the role of cathodic protection jointly, overcomes common zinc-rich
Coating is to sacrifice anti-corrosion mode of the zinc powder as cost, while the zinc salt that zinc-rich coating is generated when playing cathodic protection can be by network
Mixture complexed absorption is fallen, and will not be deposited between upper coating and zinc-rich coating and influence between upper coating and zinc-rich coating
Binding force to enhance the binding force and compatibility for applying interlayer, while greatly reducing the zinc oxide fume generated when welding,
It is environmental-friendly, there is good water resistance, acid resistance, salt spray resistance, significantly improve mechanical strength, the attachment of film
Power, anticorrosive property, weatherability, the service life is longer for coating；Ceramic powder has been complexed in complexing agent in advance, also functions to sustained release zinc source
Effect, when needing zinc source as cathodic protection, can release zinc source；
(3) the ZnO conductivity ceramics powder being added in coating material makes during ceramic powder is deposited on the lower layer of paint film or is suspended in
Between, physical barrier action is played, moisture and corrosive substance can be obstructed through coating, further enhance the water resistance of coating
And anti-corrosion capability；
(4) hydroxyl of epoxy resin and phthalic anhydride are reacted by modified epoxy, the phthalic acid asphalt mixtures modified by epoxy resin of generation
Rouge inherently at the extremely strong dispersing agent of dispersibility, can efficiently divide due to introducing highly polar carboxyl, epoxy resin
It dissipates and chelating zinc powder and ceramic powder containing zinc has reached best and prevented so that zinc powder or zinc source are evenly dispersed in corrosion-inhibiting coating
Rotten effect；
(5) present invention only needs first contain zinc ceramic powder and complexing agent, a part of organic solvent elder generation hybrid reaction, allows part zinc
Source first " complexing ", then makes zinc powder in coating material under modified epoxy and promoter effect containing dispersing agent again
In it is evenly dispersed, form the good corrosion-inhibiting coating of antiseptic property, this method prepare it is simple, at low cost, be easy to industrialized mass production.
