Description

A kind of anti-corrosion zinc-rich paint of addition neopelex composite modifier
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
According to statistics, the steel being directly lost due to corrosion every year accounts for about a quarter of steel annual output.People pass through Various modes delay the corrosion rate of steel.Wherein coating coating is a kind of common method, and 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 The normal potential of battery protection, the zinc in zinc rich paint is low compared with steel, and when corrosive medium penetrates into, steel forms former electricity with zinc powder Pond, zinc powder lose electronics as the cathode of primary battery, and steel obtains electronics as anode and protected.When the painting of zinc-rich paint The position having on film is by after mechanical damage, and in a certain range of area, anticorrosive current can also flow to steel exposed portion, then zinc Corrosion product be deposited upon there formed layer protecting film.With the continuous exposure of steel surface, zinc-rich film constantly by Protective film is covered, and cathodic protection effect is just presented inertia again, but it is mechanically damaged in film and when exposing new zinc surface Then start to bring back to life again.If exposing new zinc face with sand paper polishing film coated surface, or by film scratch, then potential difference just restores former Shape.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, 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 is often film forming binder with epoxy resin, chlorinated rubber, vinylite and polyurethane resin.But organic zinc rich paint Organic binder electric conductivity it is poor.Inorganic zinc-rich paint is divided into have solvent type and aqueous two class, wherein aqueous inorganic rich Zinc 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 dodecyl benzene sulfonic acid Natrium surfactant improves metal zinc wettability, comprehensive to prepare a kind of composite modified zinc-rich anti-corrosive paint It can will greatly improve.
