Description
Technical field
The present invention relates to a kind of anti-corrosion zinc-rich paint, more particularly to a kind of oleophosphoric acid base metatitanic acid of addition isopropyl dioctyl four
Anti-corrosion zinc-rich paint of ester and alkylphenol polyethylene oxide ether modifying agent and preparation method thereof, belongs to coating manufacture field.
Background technology
Common coating is coated in steel surface, simply to completely cut off air in the way of and prevent steel corrosion, and zinc rich paint
Air can not only be completely cut off, and galvanic cell protection can be formed, the normal potential of the zinc in zinc rich paint is low compared with steel, corrosive medium
During infiltration, steel forms galvanic cell with zinc powder, and zinc powder loses electronics as the negative pole of galvanic cell, and steel obtains electronics as positive pole
And protected.After the position having on the film of zinc-rich paint is by mechanical damage, in a range of area, anticorrosive current
Also steel exposed portion can be flowed to, then the corrosion product of zinc is deposited upon there and forms layer protecting film.Zinc rich paint is divided into be had
Machine zinc rich paint and inorganic zinc-rich are painted, and organic zinc-rich paint often uses epoxy resin, chlorinated rubber, vinylite and polyurethane
Resin is 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 again molten
Formulation and aqueous two class.Wherein aqueous inorganic zinc rich paint is by aqueous inorganic silicate（Receive, potassium, lithium）Resin, zinc powder, auxiliary agent
Deng composition.
Aqueous inorganic zinc-enriched coating is free from environmental pollution etc. excellent with free from extraneous odour, non-ignitable not quick-fried due to its organic solvent-free
Point, but simultaneously because solvent is few, wetability is low, thus adhesive force not as corresponding solvent based coating it is good, and zinc powder is added to painting
In material, merged because zinc powder and inorganic silicate are more difficult, it is low attached power with ground.Therefore, 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.Molecular fragment or group office that two class formations are completely contradicted with performance
It is connected in the two ends of same molecule and with chemical bond, forms 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 the oleophosphoric acid base titanate coupling agent of isopropyl dioctyl four and alkane
Base phenol PEO ether surface active agent, improves metal zinc wettability, prepares a kind of modified zinc-rich anti-corrosive paint.
The content of the invention
It is an object of the invention to provide a kind of modified zinc-rich anti-corrosive paint, to realize this purpose, the coating include with
The raw material of lower mass percent：
Potassium silicate 5%-10%；
Sodium metasilicate 5%-10%；
Ludox 20%-40%；
The oleophosphoric acid base titanate esters 3%-7% of isopropyl dioctyl four；
Alkylphenol polyethylene oxide ether 2%-3%；
Silicone acrylic emulsion 20%-30%；
Zinc powder 20%-30%.
A kind of preparation method of modified zinc-rich anti-corrosive paint comprises the following steps：
(1) a certain amount of potassium silicate solution and sodium silicate solution are poured into Hybrid Heating in container, temperature control is at 50-70 DEG C；
(2) in the case where ceaselessly stirring, the Ludox of metering is slowly added dropwise, is sufficiently mixed it；
(3) again toward the oleophosphoric acid base titanate esters of isopropyl dioctyl four and alkylphenol polyethylene oxide of the certain metering of addition in container
Ether, high-speed stirred is uniform；
(4) stop heating, when temperature is down to room temperature, add silicone acrylic emulsion；
(5) finally add a certain amount of super-fine zinc dust, after persistently stirring by a kind of modified zinc-rich anti-corrosive paint.
Preferential, in preparation process, the size of super-fine zinc dust particle is for more than 700 mesh.
The present invention has following advantages and characteristic：
(1) the zinc-rich anti-corrosive paint good stability for preparing；
(2) preparation process is simple, easy to operate；
(3) raw material sources enrich, with low cost.
