Description
Technical field
The invention belongs to the organic-inorganic hybrid coatings field on weathering steel surface, particularly relate to Surface Rust stabilization coating.
Background technology
Weathering steel has good weather-resistant performance, and it in use can form fine and close and stable rusty scale in surface, and this rusty scale has good erosion resistance, can effectively hinder corrosive medium to enter.The exposed use of weathering steel eliminates application and regularly rotproofing, therefore can produce good economic benefit and environmental benefit.But, during the exposed use of weathering steel, also there are some problems.First, the formation of weathering steel surface stabilization rusty scale needed for 4 to 10 years, before this, exposed weathering steel is the same with plain carbon stool produce red rust and yellow become rusty etc. loose rusty scale with become rusty liquid, the liquid sagging that becomes rusty disperses and affects outward appearance, contaminate environment.Secondly, the liquid sagging that not only becomes rusty when weathering steel uses under the marine atmosphere condition of high salt problem of dispersing is serious, and is difficult to form stable protective rust, causes that it is anti-corrosion, environment-friendly advantage can not get playing.
At present, the problem of initial stage rust liquid sagging is used to develop some weathering steel surface treatment agents for weathering steel.Publication number is that CN86103534 patent describes a kind of weather resisting anti-rust film for weathering steel and general carbon steel and forms method fast, the treatment agent of the method contains oxalic acid, tannin extract, tannic acid, hydrogen peroxide, ammonium molybdate, potassium bichromate, potassium permanganate, Sodium Nitrite, S-WAT etc., and its main process process comprises surface acid-washing, purification, oxidation, stabilization and fully sends out rust.The method processes with immersion way, is not suitable for large-scale component, complex procedures, treatment time long, and therefore this treatment agent and treatment process are not suitable for applying in environment at the scene.
Publication number is that CN102191492A patent discloses a kind of converting agent of iron rust, this transforming agent is made up of pretreatment liquid and aftertreatment fluid, pretreatment liquid contains iron powder, urotropine, G & W etc., and aftertreatment fluid contains polyphosphoric acid, manganous carbonate, acetic acid, Weibull and water; Although this transforming agent can effectively suppress corrosion by suppressing the anodic reaction process of iron and steel, but its treatment time is longer, steel part need be brushed pretreatment liquid and be sprayed aftertreatment fluid again after 1 hour, after this need placement just can obtain complete process film in 24 hours, be therefore unsuitable for implementing in the working-yard of smelter and steel and iron member.
Different on forming with above-mentioned treatment agent is a kind of compound Surface Rust of Weathering Steel stabilization treatment coating (Liu Lihong be made up of phosphatize phosphate coat, resin and silicon sol; Li Ming; Li Xiao is firm; Acta Metallurgica Sinica; 2004; 40 (11): 1195-1199), this coating can prevent rust liquid sagging and promote that protective rust generates.Weathering steel is first carried out pre-treatment by this technology in Zn-Ca based phosphatization liquid, then applies the composite coating that is made up of water soluble acrylic resin and silicon dioxide gel and at about 120 DEG C film-formings.Obviously, this treatment technology operation is loaded down with trivial details and film needs hot setting, therefore is unsuitable for on-the-spot practical application.
Summary of the invention
The object of the invention is to overcome the problems referred to above and not enough and provide a kind for the treatment of process simple, be adapted at the Surface Rust of Weathering Steel stabilization treatment coating that uses in site environment.
A kind of Surface Rust of Weathering Steel stabilization coating, it is characterized in that, its composition is by mass percentage: polyvinyl butyral resin 4.1% ~ 6.5%; Chromium sulphate 8.5% ~ 8.7%; Rust inhibitor 3.7% ~ 5.7%; Iron oxide red 12.9% ~ 13.2%; Barium sulfate 28.3% ~ 28.9%, surplus is solvent dehydrated alcohol;
Rust inhibitor is Sodium orthomolybdate, also can containing at least one in phosphorus zinc white and talcum powder in rust inhibitor, and phosphorus zinc white is 0 ~ 1.0% by mass percentage, and talcum powder is 0 ~ 2.0% by mass percentage.
Polyvinyl butyral resin is the organic film former in coating, this resin ambient temperature curable, forms organic network, and the inorganic components in parcel, adhesive coating material is also attached to steel substrate; When polyvinyl butyral resin content is too low, coating film-forming properties is poor, stable Organic-inorganic hybrid can not be formed, cause coating performance not good, be unfavorable for the stabilization of rusty scale during too high levels, therefore in coating, polyvinyl butyral resin controls 4.1% ~ 6.5%.
Chromium sulphate is as the properties-correcting agent in coating, and its effect is the structural state changing steel surface film, improves the stability of coating and corrosion product, and makes corrosion product possess self-reparing capability; When chromium sulphate content is too low, corrosion product stability is not good, and worsen coating film-forming properties during too high levels, therefore in coating, chromium sulphate controls 8.5% ~ 8.7%.
When rust inhibitor content is too low, coating corrosion resistance is not good, and too high levels is unfavorable and increase coating cost to coating adhesion, and therefore, rust inhibitor controls 3.7% ~ 5.7%.At least containing Sodium orthomolybdate in rust inhibitor, also can containing at least one in phosphorus zinc white and talcum powder; Sodium orthomolybdate and phosphorus zinc white all can form passivation product at steel surface, thus hinder corrosive medium to the infiltration of steel substrate, and especially Sodium orthomolybdate can effectively suppress chlorion to the disadvantageous effect of corrosion product compactness; Talcum powder can form multibarrier in the coating, delays the diffusion of corrosive medium to coat inside.
Iron oxide red adds in coating as pigment, the core of stabilization oxide compound in tarnishing processes also can be become except playing covering effect, thus be conducive to the formation of stabilization rusty scale, when its add-on is too low, not good, the coating stabilization of coating opacifying power turns into not obvious, when add-on is too high, coating film-forming properties is deteriorated, and therefore in coating, iron oxide red controls 12.9% ~ 13.2%.
Barium sulfate is for adjusting the rheological property of coating and serving as film forming matter, and when its content is too low, paint flow levelling is not good, and during too high levels, coating becomes film uniformity to be deteriorated, and therefore in coating, barium sulfate controls 28.3% ~ 28.9%.
Surface Rust of Weathering Steel stabilization coating of the present invention adopts general Paint preparation technology method to obtain, and coating composition of the present invention and treatment process are simply, adopts brushing mode to apply, does not need multi-step process; Namely curable and set time is short under coating normal temperature condition, be adapted at smelter and working-yard is implemented.Coating can improve the solidity to corrosion of weathering steel matrix, and improves surface rust liquid sagging phenomenon.
