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
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 former electricity
Pond is protected, and the normal potential of the zinc in zinc rich paint is low compared with steel, and when corrosive medium penetrates into, steel forms primary battery, zinc with zinc powder
Powder loses electronics as the cathode of primary battery, and steel obtains electronics as anode and protected.Have when on the film of zinc-rich paint
Position by after mechanical damage, in a certain range of area, anticorrosive current can also flow to steel exposed portion, then zinc corrosion production
Object is deposited upon there and forms layer protecting film.With the continuous exposure of steel surface, zinc-rich film is constantly hidden by protective film
Lid, cathodic protection effect are just presented inertia again, but mechanically damaged in film and while exposing new zinc surface then starts to bring back to life.
Zinc rich paint is divided into organic zinc rich paint and inorganic zinc-rich paint, 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-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 is due to its organic solvent-free, with free from extraneous odour, no
Combustion it is not quick-fried, it is free from environmental pollution the advantages that, be widely used.
For aqueous inorganic zinc-enriched coating since 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 it is this
Improvement is often limited, in preparation process, then adds suitable surfactant, then can play better improvement result.
The present invention is by dope preparing process, on the one hand adding γ-glycydoxy trimethoxy silicon
Alkane coupling agent improves the compatibility of metal zinc and silicate, enhances the adhesive force of coating, on the other hand, also adds dodecane
Base benzene sulfonic acid sodium salt surfactant improves metal zinc wettability, comprehensive to promote zinc-rich paint performance.
