Description
Technical field
The present invention relates to a kind of zinc-rich paint, more particularly to a kind of anti-corrosion zinc-rich paint for adding complexing agent and its preparation side
Method belongs to coating manufacture field.
Background technology
The economic loss caused by metal erosion accounts for about the 2%-4% of various countries GDP, the gold scrapped due to corrosion every year in the whole world
Belong to up to hundred million tons or more.Metal erosion can significantly reduce the mechanical properties such as the intensity, plasticity, toughness of metal material, destroy metal structure
The geometry of part increases the abrasion between part, deteriorates the physical properties such as electrical and optical, shortens the service life of equipment, very
To causing the catastrophic failures such as fire, explosion.Steel is similarly faced with corrosion as a kind of most common metal material used
This problem mesh.According to statistics, the steel being directly lost due to corrosion every year accounts for about a quarter of steel annual output.People
Delay the corrosion rate of steel by various modes.
Common coating is coated in steel surface, only prevents steel corrosion in a manner of completely cutting off air, and zinc rich paint
Air can not only be completely cut off, and primary battery protection can be formed, the normal potential of the zinc in zinc rich paint is low compared with steel, corrosive medium
During infiltration, steel forms primary battery with zinc powder, and zinc powder loses electronics as the cathode of primary battery, and steel obtains electronics as anode
And it is protected.After the position having on the film of zinc-rich paint is by mechanical damage, in a certain range of area, anticorrosive current
Also steel exposed portion can be flowed to, then the corrosion product of zinc is deposited upon there and forms layer protecting film.With steel surface
Constantly exposure, zinc-rich film are constantly covered by protective film, and inertia is just presented, but in film by machine in cathodic protection effect again
Tool then starts to bring back to life when damaging and exposing new zinc surface.If expose with sand paper polishing film coated surface or by film scratch new
Zinc face, then potential difference just restore to the original state.In addition, anion binding in the zinc ion and corrosive medium that are dissolved out and formed
Basic zinc salt and zinc-iron double salt, fill up the crack of film, and reach the etch-proof purpose of isolation.Zinc rich paint is divided into organic zinc-rich
Paint and inorganic zinc-rich paint, organic zinc-rich paint are often with epoxy resin, chlorinated rubber, vinylite and polyurethane resin
Film forming binder.But the electric conductivity of the organic binder of organic zinc rich paint is poor.Inorganic zinc-rich paint be divided into for have solvent type and
Aqueous two class.Wherein aqueous inorganic zinc rich paint is by aqueous inorganic silicate(It receives, potassium, lithium)The groups such as resin, zinc powder, auxiliary agent
Into.
Aqueous inorganic zinc-enriched coating has free from extraneous odour, non-ignitable not quick-fried due to its organic solvent-free, free from environmental pollution etc. excellent
Point, but simultaneously because solvent is few, wetability is low, thus adhesive force not as good as corresponding solvent based coating it is good, and zinc powder is added to painting
In material, due to zinc powder with inorganic silicate is more difficult merges, it is low attached power with ground.For this purpose, generally in dope preparing process, add
Add coupling agent, improve the compatibility of metal zinc and silicate, enhance the adhesive force of coating, but this improvement often has
Limit, in preparation process, then adds suitable surfactant, then can play better improvement result.
The present invention is by dope preparing process, except addition N-2- (aminoethyl) -3 aminopropyltriethoxy dimethoxysilane
Coupling agent improves the compatibility of metal zinc and silicate, enhances the adhesive force of coating, while also add dodecyl benzene sulfonic acid
Natrium surfactant improves metal zinc wettability, comprehensive so as to prepare a kind of composite modified zinc-rich anti-corrosive paint
It can will greatly improve.
