Description
Technical field
The present invention relates to a kind of water-fast zinc-rich paint, more particularly to the water-fast zinc-rich paint of a kind of addition composite modifier and
Preparation method belongs to coating manufacture field.
Background technology
Loss is countless caused by steel corrosion every year in the whole world, and steel anti-corrosive is of increasing concern, and people pass through
Various modes delay the corrosion rate of steel, wherein coating coating is a kind of common method.Common coating 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 can form original
Battery protection.Since the normal potential of zinc is low compared with steel, when corrosive medium penetrates into, steel forms primary battery with zinc powder, and zinc powder is made
Electronics is lost for the cathode of primary battery, steel obtains electronics as anode and protected.When what is had on the film of zinc-rich paint
Position is by after mechanical damage, and in a certain range of area, anticorrosive current can also flow to steel exposed portion, then the corrosion production of zinc
Object is deposited upon there and forms layer protecting film.With the continuous exposure of steel surface, zinc-rich film is constantly by protective film institute
It covers, cathodic protection effect is just presented inertia again, but and when exposing new zinc surface then beginning mechanically damaged in film
It brings back to life.If exposing new zinc face with sand paper polishing film coated surface, or by film scratch, then potential difference just restores to the original state.In addition, molten
It solves the anion binding in zinc ion and corrosive medium out and forms basic zinc salt and zinc-iron double salt, fill up splitting for film
Seam, and reach the etch-proof purpose of isolation.And it due to being water-based paint, avoids organic solvent from endangering the health of construction personnel, has
There is environmental-protection function.
Zinc-rich paint is divided into organic zinc-rich paint and inorganic zinc coating, and organic zinc-rich paint often uses epoxy resin, chlorination
Rubber, vinylite and polyurethane resin are film forming binder.But the electric conductivity of the organic binder of organic zinc-rich paint is poor.
Inorganic zinc coating is divided into have solvent type and aqueous two class.Wherein aqueous inorganic zinc-enriched coating is by aqueous inorganic silicate
(It receives, potassium, lithium)The compositions such as resin, zinc powder, auxiliary agent.Silicate mainly has lithium metasilicate, Gui Suan Na etc., lithium metasilicate price height and thermal change
Property is poor;Sodium metasilicate is easily carbonized.And using ammonium silicate as base-material, price is low, and water resistance is good.
Since aqueous inorganic zinc-enriched coating 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 in coating, zinc powder with inorganic silicate is more difficult merges, it is low attached power with ground.For this purpose, generally being applied in zinc-rich
Expect in preparation process, add coupling agent, improves the compatibility of metal zinc and silicate, enhance the adhesive force of coating, but this
Kind improvement is often limited, in preparation process, then adds suitable surfactant, then can play better improvement and make
With.
The present invention passes through in dope preparing process, on the one hand, poly alkyl alcohol ethylene oxide ether surface active agent is also added,
Improve metal zinc wettability, on the other hand add γ-methacryloxypropyl trimethoxy silane coupling agent, improves gold
The compatibility for belonging to zinc powder and silicate, enhances the adhesive force of coating, to prepare a kind of water-fast zinc-rich modification haveing excellent performance
Coating.
