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
Coating is on steel surface during application, and traditional technology requires thoroughly rust cleaning, and even require to expose metallic matrix true qualities completely, this is part very heavy work, and not only had a strong impact on production efficiency, executive cost is high, and rust dirt is detrimental to health; And at some band large-scale metal structures as bridge, traffic guardrail, big machinery and facility cannot carry out thorough surface treatment especially.Therefore be just necessary to develop a kind of can the new coating-Rust-resisting coating of direct brushing corrosion steel surface.
Corrosion general on hardware can not only change into stable " harmless rust " by Rust-resisting coating, and has common rust proof paint function concurrently simultaneously.Begin one's study from the end of the fifties in last century, since the mid-1960s is applied, the research of Rust-resisting coating is very active, develops also very rapid, kind is a lot, has: alkyd, epoxy, oiliness phenolic aldehyde, epoxy-coal tar, epoxy-polyvinyl butyral acetal etc. by film-forming resin classification.Can be divided into by rust-proofing action principle: osmosis type, transformant and stable form.But judging from the current situation, be adopt organism to be the oiliness on rust paint of solvent or dispersion medium mostly in existing kind, big for environment pollution, energy consumption is high, dangerous and be not expected.Thus, research and development waterborne rusted paint is not only beneficial to environment protection, and has saved a large amount of organic resource, the novel aqueous Rust-resisting coating of the one that the present invention researchs and develops just under these circumstances.
Steel surface first get rusty and the attachment of iron and steel ground more firm, but along with the carrying out of corrosion, originally nascent rust is aging gradually, below new rust constantly generate, therefore iron rust layer is two-layer inside and outside comprising.Skin is floating rust, and loose porous and iron and steel ground adheres to loosely, and with wire brush once brushing, internal layer is jail rust, and it is more firm with the attachment of iron and steel ground.On rust paint due to its internal performance can by rust transformation with stable in the coating.
From composition, iron rust is made up of the mixture of stable iron cpd and active iron cpd, according to this feature of iron rust, on rust paint is except must having the performance of 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, rusty scale is bondd becomes continuous print closure coating, closes whole rusty scale and steel surface; (2) enough reactivities must be had to rusty scale, iron cpd active in rusty scale can be made to pass 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, provides a kind of environment-friendly type aqueous on rust paint and preparation method thereof.
The technical solution used in the present invention is as follows:
Waterborne rusted paint, is characterized in that, its raw material is made up of following weight proportion:
Wherein, the preparation method of described Crosslinked Styrene-Acrylate Emulsion is: using 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, with 2 ~ 2.5 parts of OP-10 for emulsifying agent, ammonium persulphate is initiator, adopts semi-continuous emulsion polymerizing method polymerization preparation, polymerization temperature 75 ~ 80 DEG C, polymerization time 2 ~ 3 hours, obtained Crosslinked Styrene-Acrylate Emulsion solid content is 45 ± 1%.

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., Crosslinked Styrene-Acrylate Emulsion is prepared;
2., being mixed with 8 ~ 12 parts of water and carry out grinding distribution to fineness by rust-stabilising pigment is 20 ~ 60 microns;
1. and 2. 3., mixing, and adds transforming agent, inversion accelerating agent, defoamer, film coalescence aid, thickening material and excess water, stirs, obtains waterborne rusted paint.
The present invention is on the basis of Crosslinked Styrene-Acrylate Emulsion membrane formation mechanism, and by the major ingredient such as Crosslinked Styrene-Acrylate Emulsion and other film coalescence aid screening and composite, working out with Crosslinked Styrene-Acrylate Emulsion is the waterborne rusted paint of main film-former.Product has nontoxic, harmless, pollution-free, simple to operate, the feature such as raw material sources are extensive, price is low, cleaner production.
Waterborne rusted paint of the present invention and preparation method thereof, compared with prior art, its advantage shows:
1, product is not substantially containing Elements in Organic Solvents, environmentally friendly, pollution-free.
2, product film formation time is short, good leveling property.
3, preparation method is simple, easy construction, favorable rust preventing effect.
