Description
Technical field
The invention belongs to coating science and technology field, particularly relate to a kind of aqueous large arch dam antistatic coating and preparation thereof
Method.
Background technology
Substantial amounts of electronic product is had to reach more than 10,000,000,000 dollars because of electrostatic damage, loss in recent years every year.With regard to furniture
Speech, is especially easy to the phenomenon that electrostatic shock is numb occur in dry autumn and winter season, because the reason furniture of Electrostatic Absorption
Also it is easy to stain dirty.
Containing substantial amounts of benzene,toluene,xylene and derivant thereof in oil paint product, VOC emission is high, direct harmful to human
Healthy.Pollute big, serious to environmental disruption.Oil paint belongs to highly flammable article, there is pole during storage transport
Big potential safety hazard.Along with appearance and the gradually enhancing of people's environmental consciousness of relevant laws and regulations, the application of environment-friendly type coating is carved
Do not allow to delay.Traditional solvent-borne coating, because a large amount of VOCs (VOC) and hazardous air pollutants contained by it, makes
With being increasingly restricted.Therefore, the attention rate suffered by free of contamination water paint is more and more higher.
Antistatic coating is mainly addition type at present, and the conductive additive used mainly has two classes: a class is antistatic
Filler, another kind of is antistatic additive.Antistatic additive mostly is polarity or the low molecular weight surfactant of ion-type of such as alkylsulfonate etc.
Activating agent, they can only bring relatively low electric conductivity to coating, and service life is short and can constantly move to surface and is consumed.
The coating electric conductivity using antistatic additive is the biggest by the such environmental effects such as humiture, friction.Currently used more antistatic
Filler such as conductive black, graphite, metal and metal oxide powder etc. differ greatly with polymer architecture, poor dispersion
Cause being not easy to generate homogeneous system, thus have influence on the physical property of electric conductivity and coating.
Common water borne coating is not the highest due to solid content, and paint film richness is inadequate, causes the finished product visual effects such as furniture
Not good enough.Therefore aqueous large arch dam antistatic finish paint as a kind of easy antistatic and reaches preferable visual effect
Mode increasingly paid close attention to by people.
Summary of the invention
Based on this, in order to solve the defect that above-mentioned prior art exists, the invention provides one and there is good thing simultaneously
Environment-friendly type aqueous large arch dam antistatic coating of reason mechanical performance and chemical-resistance and preparation method thereof.

Fat and low acid number carboxyl polyester resin.
Wherein in some embodiments, described coating is made up of the raw material of following weight/mass percentage composition:
Wherein in some embodiments, described conductive filler is the mixture of white carbon black, zinc powder and copper powder, wherein said mixing
In thing, content of carbon black is no less than 18%, and described zinc powder uses zinc flake, zinc powder with the weight ratio of copper powder not less than 2:1, zinc powder
Electric conductivity own is excellent, and copper powder with the use of and ratio account for major part can to reduce copper powder significantly oxidized
Probability.
Wherein in some embodiments, described coalescents is dipropylene.
Wherein in some embodiments, described pH adjusting agent is triethanolamine.
Wherein in some embodiments, described function additive includes wetting agent, emulsifying agent, dispersant, defoamer, levelling agent
And leveling auxiliary agent.
Wherein in some embodiments, described wetting agent mass content in described coating is 0.1-0.5%；Described breast
Agent mass content in described coating is 0.2-0.7%；Described dispersant mass content in described coating is 0.5-
1.5%；Described defoamer mass content in described coating is 0.2-0.8%；Described levelling agent matter in described coating
Amount content is 0.1-0.3%；Described leveling auxiliary agent mass content in described coating is 0.3-1.2%.
Wherein in an embodiment, described wetting agent is TEG0245；Described emulsifying agent is T-S；Described dispersant is
BYK-190；Described defoamer is TEG0805；Described levelling agent is BYK-333；Described leveling auxiliary agent is RM2020.
Present invention also offers the preparation method of above-mentioned aqueous large arch dam antistatic coating, comprise the following steps: first will
Hydroxyl polyurethane resin, function additive add in reactor fully emulsified, then functional powder and conductive filler are sequentially added into
Reactor high speed is disperseed, and obtains homodisperse emulsion, finally coalescents, pH adjusting agent and water is added reactor, adjusts
Joint system pH and viscosity, after stable system, to obtain final product.
The aqueous large arch dam antistatic coating of the present invention, raw material include the polyurethane aqueous resin containing oh group,
Waterborne conductive filler and the carboxyl polyester resin powder body of different acid number gradient, the polyurethane aqueous resin containing oh group passes through
Emulsifying agent and dispersant wetting agent emulsifying, add the polyester resin powder body containing carboxylic group according to equivalent relation, in liquid phase
High speed is disperseed, owing in carboxyl polyester resin powder body, carboxyl-content exists certain gradient, and dispersed in the liquid phase, because of
This, by adjusting the pH value of system so that the hydroxyl polyurethane resin in liquid phase and the polyester resin powder body containing carboxylic group
Occur multiple polyester cross-linking to react on one, form a special hybrid, after construction, during drying varniss, along with
The minimizing of moisture, the volatilization of triethanolamine, the pH value of system declines, and polyester resin powder body and some polyurethanes resin crosslink

Every combination property of antistatic coating is the most excellent.Conductive filler used in the embodiment of the present invention 1～6 is flake powder
End, obtains, by use ratio, the film that antistatic property is excellent；Functional powder used, has the splendid transparency, both
Serve as filler, identify oneself with in cross-linking reaction as reactant again so that it is transparent that film compactness is strong, richness is high and splendid
Degree.By in the carboxyl polyester resin power applications of high glass transformation temperature to water paint, water paint and thermosetting are played
The double dominant of powdery paints, has expanded thinking, and has been successfully applied to practice.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
