Abstract
The invention discloses a rusty cold spraying coating zinc paint and a preparation method thereof. The paint adopts rust removal active ingredients and is prepared by compounding the rust removal active ingredients comprising sodium citrate, sodium sulfite and urotropine. According to the rusty cold spraying coating zinc paint and the preparation method thereof, provided by the invention, red rust on the surface of rolled steel can be converted into black iron oxide, a stronger preservative effect is produced through combination of an insulating layer and zinc powder, therefore during spray construction, coating can be performed only after rust and greasy dirt on the surface are cleaned, and besides, the paint provided by the invention has the advantages of simple application, long rust-proof cycle and good rust-proofing effect and the like.
Description
Technical field
The invention belongs to steel just surperficial antirust treatment field, particularly relate to a kind of band rust cold spraying film zinc paint with and preparation method thereof.
Background technology
Steel construction has the series of advantages such as intensity is high, good toughness, easy to make, speed of application is fast, building cycle is short, and obtains applying more and more widely in modern architecture industry.But it holds corrosion-prone feature and but brings huge loss to national economy.Spraying steel structure anti-corrosion paint is one of measure of economical rationality the most in anticorrosion of steel structure measure.
The antirust treatment of steel surface is divided into antirust and finally antirust three kinds of methods and the requirement of rust prevention during manufacture, manufacturability usually.Rust prevention during manufacture process generally adopts aq. type antirust, and dewater antirust corrosion protection method such as grade, and antirust time is short, can meet the antirust requirement of inter process.Manufacturability antirust treatment has that passivation is antirust, phosphatization antirust, dewatering rust preventive oil etc., is different because of the difference of processing requirement.Final antirust treatment is antirust based on oiliness.Because antirust grease is not volatile, so its antirust time is longer.
China's steel rust prevention technological development is scarcely out of swaddling-clothes, and people are short in understanding to antirust consciousness or rust-proofing method, the anti-corrosive technology of employing and product or some traditional concepts.Along with developing rapidly of China's industrial technology, antirust problem becomes the theme that people are concerned about gradually, the series product such as phosphorization product, passivation product, blackout product, water-based antirust, dewatering rust preventive oil, hard film rust preventives and cutting rust protection liquid.
During general steel construction brushing protective system, there is certain thickness corrosion layer at its part surface, for common protective system, thoroughly must remove iron rust, coating has directly been contacted with steel surface, to ensure the antiseptic power of coating.In antiseptic project, executive cost accounts for more than 70%, and the surface treatment (eliminating rust, except wet goods) wherein based on sandblasting accounts for more than 70%.The requirement of current people to environment is more and more higher, and therefore, water-based anticorrosive paint has obtained and developed rapidly, and range of application constantly expands, and product performance also improve constantly.In protective system field, effects on surface process lower than Sa2 level, and is with moisture, the upper protective system applicatory in band oil surface proposes very high requirement.
Just there is much extremely successful metal anticorrosion water-soluble coating system in the world at present, as helped the water-based anticorrosive paint auxiliary plan of honest paint, just have passed NORSOK standard test accreditation the harshest in the world.But existing more successful water-based anticorrosive paint is all the separately brushing of bottom surface paint, construction trouble, but also will consider the matching capacity problem paint bottom surface, bottom surface paint does not match, and by the bonding affecting bottom surface and paint, affects the corrosion resistance nature of coating.And the aqueous corrosion resisting paint without need of cleaning rust of current bottom surface unification has certain requirement to ground, require that rusty scale thickness is lower than 80 μm, and the equal price of selected starting material is higher, adds the cost of coating.As CN1458197A has selected water-latex type synthetic resins and water high light pool varnish, CN1288919A has selected the one in oleum lini, TriMethylolPropane(TMP), m-phthalic acid or phthalic anhydride, and the composition such as MALEIC ANHYDRIDE, trimellitic acid 1,2-anhydride, acrylate, butyl glycol ether, butanols, the starting material that price is relatively high all selected by two kinds of coating, improve coating cost, and rusty scale be there are certain requirements, must make it before brushing to reach required thickness.
Therefore, a kind of band rust of development cold spraying film zinc paint is for being badly in need of.
Summary of the invention
