Description
Technical field
The present invention relates to a kind of methods for improving water paint water resistance, belong to aqueous anticorrosion paint field.
Background technique
Currently, the antirust paint that China uses on the market is substantially also all using gasoline, kerosene or machinery oil as solvent, all
It is the product that petroleum fractionating comes out, because the aromatic hydrocarbon being contained in inside petroleum can not be made to take off, so gasoline, kerosene and machinery oil
All contain aromatic hydrocarbon.Solvent naphtha is done using gasoline, kerosene, first is that its flash-point is low, is easily caught fire, second is that pollution environment, is harmful to
The health of people.
With the continuous propulsion of Environmental Protection in China cause, it has been trend of the times, water paint that oil paint is substituted by water paint
Be free of no or rare three industrial wastes discharge in the substance production being perhaps harmful to the human body containing a small amount of aromatic hydrocarbon, lead etc..
But water paint is still difficult to accomplish heavy antisepsis effect both at home and abroad at present.This is very unfavorable for anti-corrosion.Therefore, it studies
The process for improving aqueous anticorrosion paint performance is just particularly important.
Summary of the invention
The purpose of the present invention is aiming at the problems existing in the prior art, provide a kind of side for improving water paint antiseptic property
Method.
The method that the present invention improves water paint antiseptic property, is by adulterating Fe in water paint3O4Nano particle or/and
Redox graphene improves water paint antiseptic property.The specific method is as follows: by Fe3O4Nano particle or/and oxygen reduction fossil
Black alkene ultrasonic disperse obtains uniform dispersion liquid in water or n,N-Dimethylformamide；Uniform dispersion liquid is added to again
(general 4 ~ 6h) in water paint, is sufficiently stirred, the water paint of antiseptic property raising can be obtained.
Fe3O4Nano particle and/or redox graphene are scattered in N, N- dimethyl formyl with the ratio of 20 ~ 80mg/ml
In amine.
Fe3O4The additive amount of nano particle or/and redox graphene is the 1 ~ 4% of water paint quality.
When dopant is Fe3O4When nano particle and redox graphene, Fe3O4Nano particle and reduction-oxidation graphite
The mass ratio of alkene is 1:2 ~ 1:8.
Below for digging excellent board water paint, water paint antiseptic property is improved to the present invention by the change of microscopic appearance
Ability is described further.
Fig. 1 is the microscopic appearance (SEM figure) for the metal iron plate film that water paint is done, and wherein a is undoped water paint, b
To adulterate redox graphene/ferroso-ferric oxide water paint, c is the water paint for adulterating redox graphene, and d is doping
The water paint of ferroso-ferric oxide.
As seen from Figure 1, undoped water paint film coated surface has many deeper micropores, in doping oxygen reduction fossil
Black alkene/ferroso-ferric oxide, redox graphene or Fe3O4After, film coated surface does not occur more profound and subtle hole, illustrates oxygen reduction
Graphite alkene/ferroso-ferric oxide, redox graphene or Fe3O4Its micropore can be effectively clogged, so that film coated surface more adds
It is whole, it is more advantageous to barrier corrosive medium in this way and reaches metallic matrix, so as to preferably play corrosion-resistant effect.Compare and
Speech, the film surface for adulterating redox graphene/ferroso-ferric oxide water paint are more complete.Main cause, oxygen reduction fossil
The large specific surface area of black alkene has high impermeabilisation ability, and it is high that high obstructing performance has it in terms of corrosion-inhibiting coating
Application value can effectively prevent H2O、O2, the corrosive mediums such as a variety of inorganic ions reach metallic substrates.But reduced graphene is
It is prepared after graphene oxide is restored, in reduction process, redox graphene piece will appear rejected region, therefore,
Its rejected region can be clogged by the way that inorganic nano rice corpuscles is added, keeps it more complete.
Detailed description of the invention
Fig. 1 is that the SEM of water paint film schemes.
