Abstract
The invention relates to a method for preparing a modified zinc-enriched anti-corrosion coating. Because a general water-based inorganic zinc-enriched coating is few in solvents and low in wetting property, the zinc-enriched coating is low in adhesion force and easy to settle. The method comprises the following steps: adding a trimethyl aluminate coupling agent and an alkylphenol polyoxyethylene ether surfactant in the process of preparing the zinc-enriched anti-corrosion coating, so that the wetting property of the metal zinc powder is synergetically improved, and the fusion property of the zinc powder and inorganic silicate is improved, therefore, the modified zinc-enriched anti-corrosion coating is obtained. The method disclosed by the invention is simple in preparation process, easy to operate and low in cost.
Description
Technical field
The present invention relates to a kind of composite modified coating of anti-corrosion zinc-rich, more particularly to a kind of addition aluminic acid trimethyl and alkyl phenol
Anti-corrosion zinc-rich paint of PEO ether modifying agent and preparation method thereof, belongs to coating synthesis field.
Background technology
Zinc rich paint can not only completely cut off air, and can form galvanic cell protection, the normal potential of the zinc in zinc rich paint
Low compared with iron and steel, when corrosive medium penetrates into, iron and steel forms galvanic cell with zinc powder, and zinc powder loses electronics, steel as the negative pole of galvanic cell
Iron obtains electronics and is protected as positive pole.After the position having on the film of zinc-rich paint is by mechanical damage, in certain model
In the area for enclosing, anticorrosive current can also flow to iron and steel exposed portion, then the corrosion product of zinc is deposited upon there and forms one layer of guarantor
Cuticula.Zinc rich paint is divided into organic zinc rich paint and inorganic zinc-rich paint, and organic zinc-rich paint commonly uses epoxy resin, chlorination rubber
Glue, vinylite and polyurethane resin are film forming binder.But the electric conductivity of the organic binder of organic zinc rich paint is poor.Nothing
Machine zinc rich paint is divided into again solvent-borne type and aqueous two class, and wherein aqueous inorganic zinc rich paint is by aqueous inorganic silicate（Receive,
Potassium, lithium）Resin, zinc powder, auxiliary agent etc. are constituted.
Aqueous inorganic zinc-enriched coating due to its organic solvent-free, with free from extraneous odour, do not fire it is not quick-fried, it is free from environmental pollution etc. excellent
Point, but simultaneously because solvent is few, wetability is low, thus adhesive force is good not as corresponding solvent based coating, and zinc powder is added to painting
In material, due to zinc powder and the more difficult fusion of inorganic silicate, attached power with ground low.For this purpose, it is general in dope preparing process, add
Plus coupling agent, improve the compatibility of metal zinc and silicate, strengthen the adhesive force of coating, but this improvement often has
Limit, in preparation process, then adds appropriate surfactant, then can play better improvement result.
Surfactant molecule is all made up of the hydrophilic group and nonpolar hydrophobic group two parts of polarity, surfactant
One end of molecule is the hydrophobic group of non-pole oleophylic, otherwise referred to as lipophilic group；The other end of molecule is the hydrophilic group of polar hydrophilic,
Otherwise referred to as lipophobic group or visually be referred to as hydrophilic head.Two class formations and the diametrically opposite molecular fragment of performance or group office
It is connected in the two ends of same molecule and with chemical bond, defines a kind of asymmetric, polarity structure, thus imparts such
Particular molecule is not only hydrophilic but also oleophylic, and is not overall hydrophilic or oleophylic characteristic, so as to play the characteristics such as wetting, solubilising.
The present invention is by dope preparing process, adding aluminic acid trimethyl coupling agent and alkylphenol polyethylene oxide ether table
Face activating agent, collaboration improves the wettability of metal zinc, increases the amalgamation of zinc powder and inorganic silicate, so as to prepare one kind
Modified zinc-rich anti-corrosive paint.
