Abstract
The present invention relates to a kind of preparation method of the coating of addition composite modifier.Aqueous inorganic zinc-enriched coating is low because of wettability, and poor adhesive force, and easily there is sedimentation.To overcome the shortcoming, this method is, in zinc-rich paint preparation process, addition amino silicone alkanes coupling agent and alkylphenol polyethylene oxide ether surface active agent, both collaborations improve the wettability of metal zinc, increase the amalgamation of zinc powder and inorganic silicate, so as to prepare a kind of modified zinc-rich anti-corrosive paint.It is its preparation process is simple, easy to operate and with low cost.
Description
Technical field
The present invention relates to a kind of anti-corrosion zinc-rich paint and preparation method, more particularly to a kind of addition amino silicone alkanes coupling agent
With the anti-corrosion zinc-rich paint of alkylphenol polyethylene oxide ether modifying agent and preparation method thereof, belong to coating synthesis field.
Background technology
Zinc-rich paint can not only completely cut off air, and can form galvanic element 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 element with zinc powder, and zinc powder loses electronics, steel as the negative pole of galvanic element
Ferrum obtains electronics as positive pole and is protected.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 two class of solvent-borne type and aqueouss, 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, wettability 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；Hydrophilic group of the other end of molecule for 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 structure of asymmetric, polarity, thus impart such
Particular molecule was not only hydrophilic, but also oleophylic, and was not the characteristic of overall hydrophilic or oleophylic, so as to play the characteristics such as moistening, solubilising.
The present invention is by, in the preparation process of aqueous inorganic zinc-enriched coating, adding amino silicone alkanes coupling agent and alkyl phenol
Poly(ethylene oxide) ether surface active agent, both collaborations improve the wettability of metal zinc, and increase zinc powder is melted with inorganic silicate
Conjunction property, so as to prepare a kind of modified zinc-rich anti-corrosive paint.
