Description
Technical field
The present invention relates to a kind of zinc-rich paint, more particularly to the anti-corrosion zinc-rich paint of a kind of addition 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 by 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.Wherein coating coating is a kind of common method, common to apply
Material is coated in steel surface, only prevents steel corrosion in a manner of completely cutting off air, and zinc rich paint can not only completely cut off air,
And primary battery protection can be formed, and the normal potential of the zinc in zinc rich paint is low compared with steel, when corrosive medium penetrates into, steel and zinc
Powder forms primary battery, and zinc powder loses electronics as the cathode of primary battery, and steel obtains electronics as anode and protected.Work as richness
The position having on the film of spelter coating is by after mechanical damage, and in a certain range of area, anticorrosive current can also flow to steel dew
Go out part, then the corrosion product of zinc is deposited upon there and forms layer protecting film.With the continuous exposure of steel surface, zinc-rich applies
Film is constantly covered by protective film, and cathodic protection effect is just presented inertia again, but mechanically damaged in film and expose new
Zinc surface when then again start to bring back to life.If exposing new zinc face with sand paper polishing film coated surface, or by film scratch, then potential difference
Just it restores to the original state.In addition, anion binding in the zinc ion and corrosive medium that are dissolved out and form basic zinc salt and zinc-iron
Double salt, fills up the crack of film, and reaches 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 is often film forming binder with epoxy resin, chlorinated rubber, vinylite and polyurethane resin.But have
The electric conductivity of the organic binder of machine zinc rich paint is poor.Inorganic zinc-rich paint is divided into have solvent type and aqueous two class.Wherein
Aqueous inorganic zinc rich paint is by aqueous inorganic silicate（It receives, potassium, lithium）The compositions such as resin, zinc powder, auxiliary agent.
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, improves 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, removing 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 adding methoxyl group fatty acid amide
Base benzene sulfonic acid sodium salt surfactant improves metal zinc wettability, to prepare a kind of composite modified zinc-rich anti-corrosive paint,
Its comprehensive performance will greatly improve.
