Description
Technical field
The present invention is applicable to the application over rust technical field of steel construction and steel workpiece, is specifically related to a kind of waterborne rusted paint and preparation method thereof.
Background technology
During application, traditional technology requires thoroughly rust cleaning to coating on steel surface, even requires to expose the metallic matrix true qualities fully, and this is very heavy work of part, has not only had a strong impact on production efficiency, and executive cost is high, and rust dirt is detrimental to health; And on some large-scale metal structures such as bridge, traffic guardrail, big machinery and facility, can't carry out thorough surface treatment especially.Therefore just be necessary to develop a kind of new coating-Rust-resisting coating of directly brushing corrosion steel surface.
Rust-resisting coating can not only change into corrosion general on the hardware stable " harmless rust ", and has simultaneously common rust proof paint function concurrently.Begin one's study from the end of the fifties in last century, since the mid-1960s was applied, the research of Rust-resisting coating was very active, developed also very rapid, kind is a lot, has by the film-forming resin classification: alkyd, epoxy, oiliness phenolic aldehyde, epoxy-coal tar, epoxy-polyvinyl butyral acetal etc.Can be divided into by the rust-proofing action principle: osmosis type, transformant and stable form.But judging from the current situation, be that to adopt organism be the oiliness on rust paint of solvent or dispersion medium mostly in the existing kind, big for environment pollution, energy consumption is high, dangerous and be not expected.Thereby the research and development waterborne rusted paint not only is beneficial to environment protection, and has saved a large amount of organic resources, a kind of novel aqueous Rust-resisting coating that the present invention researchs and develops just under these circumstances.
Steel surface first got rusty and the iron and steel ground adheres to jail, but along with the carrying out of corrosion, originally nascent rust is aging gradually, below new rust constantly generate, so the iron rust layer is two-layer inside and outside comprising.Skin is floating rust, and loose porous and iron and steel ground adheres to not firm, and once brushing, internal layer is the jail rust with wire brush, and it and iron and steel ground adhere to more firm.On rust paint is owing to its internal performance can transform iron rust and be stabilized in the coating.
On forming, iron rust is made of the mixture of stable iron cpd and active iron cpd, according to these characteristics of iron rust, on rust paint is except the performance that must have general rust proof paint, also must possess two specific functions, namely transform the function with stable iron rust: (1) coating can fully infiltrate, permeate whole loose porous rusty scale, makes the rusty scale bonding become continuous closure coating, seals whole rusty scale and steel surface; (2) to rusty scale enough reactivities must be arranged, can make iron cpd active in the rusty scale through the filler of conversion or passivation vary stable.
Summary of the invention
The present invention is intended to overcome above-mentioned the deficiencies in the prior art, and a kind of environment-friendly type aqueous on rust paint and preparation method thereof is provided.
The technical solution used in the present invention is as follows:
Waterborne rusted paint is characterized in that, its raw material is comprised of following weight proportion:
Wherein, the preparation method of described Crosslinked Styrene-Acrylate Emulsion is: with 50～60 parts of butyl acrylates as soft monomer, 40～50 parts of vinylbenzene are hard monomer, 3～4 parts of N hydroxymethyl acrylamides, and 2～5 parts of vinylformic acid are altered contents, take 2～2.5 parts of OP-10 as emulsifying agent, ammonium persulphate is initiator, adopts semi-continuous emulsion polymerizing method polymerization preparation, 75～80 ℃ of polymerization temperatures, polymerization time 2～3 hours, the Crosslinked Styrene-Acrylate Emulsion solid content that makes is 45 ± 1%.
Preferably, described transforming agent is oxalic acid and/or tannic acid.
Preferably, described inversion accelerating agent is benzenetriol.
Preferably, described rust-stabilising pigment is one or more in aluminium dihydrogen tripolyphosphate, zinc yellow, iron oxide red, zinc oxide, the barium sulfate.
Preferably, described defoamer is water-based silicone oil.
Preferably, described film coalescence aid is glycol propyl ether or butyl glycol ether.
The preparation method of waterborne rusted paint is characterized in that, comprises the steps:
1., preparation Crosslinked Styrene-Acrylate Emulsion;
2., rust-stabilising pigment being mixed and carries out grinding distribution to fineness with 8～12 parts of water is 20～60 microns;
3., mix 1. and 2., and add transforming agent, inversion accelerating agent, defoamer, film coalescence aid, thickening material and excess water, stir, namely get waterborne rusted paint.
The present invention by the major ingredient such as Crosslinked Styrene-Acrylate Emulsion and other film coalescence aid screening and composite, works out the waterborne rusted paint take Crosslinked Styrene-Acrylate Emulsion as main membrane-forming agent on the basis of Crosslinked Styrene-Acrylate Emulsion membrane formation mechanism.Nontoxic, harmless, pollution-free, simple to operate, the characteristics such as raw material sources are extensive, price is low, cleaner production that product has.
Waterborne rusted paint of the present invention and preparation method thereof, compared with prior art, its advantage shows:
1, product does not contain organic solvent composition substantially, and is environmentally friendly, pollution-free.
2, the product film formation time is short, good leveling property.
3, the preparation method is simple, easy construction, favorable rust preventing effect.
