The adopted paint system is a water-based paint system which has an excellent anti-corrosive effect in seawater, so the application range of the paint is effectively widened.
Description
Technical field
The present invention relates to technical field of metal anti-corrosion, particularly relate to a kind of high corrosion resistance metal anti-corrosive paint and preparation method thereof.
Background technology
Metallic substance damages by the effect of surrounding medium, is called metallic corrosion.The corrosion of metal is modal etch state.During corrosion, the interface of metal there occurs chemistry or electrochemistry heterogeneous reaction, make metal proceed to oxidation (ion) state.This significantly can reduce the mechanical property such as intensity, plasticity, toughness of metallic substance, destroy the geometrical shape of hardware, increase the wearing and tearing between part, worsen the physicals such as electricity and optics, in the work-ing life of shortening equipment, even cause the catastrophic failure such as fire, blast.The financial loss that U.S. 1975 causes because of metallic corrosion is 70,000,000,000 dollars, account for the 4.2%. of national economy total output value then according to statistics, the indirect loss such as stopping production, power failure that 10 ~ 20%. metallic corrosion accidents that the iron and steel loss of causing due to metallic corrosion every year accounts for output of steel then cause just more cannot calculate.Corrosion of metal phenomenon is very general.As ferrous products gets rusty (Fe
2o
3xH
2o), there is hickie (Al in aluminum products surface
2o
3), brass work surface produces verdigris [Cu
2(OH)
2cO
3], silverware surface stain (Ag
2s, Ag
2etc. O) all belong to metallic corrosion, the corrosion of the metal that wherein consumption is maximum---ferrous products is the most common.Meanwhile, corrosion also may become the obstacle of production development and scientific-technical progress.
Graphene is a kind of novel material of the individual layer sheet structure be made up of carbon atom.Be a kind ofly form with sp2 hybridized orbital the flat film that hexangle type is honeycomb lattice by carbon atom, only have the two-dimensional material of a carbon atom thickness.Graphene is the thinnest in the world is at present the hardest nano material also, and it is almost completely transparent, only absorbs the light of 2.3%; Thermal conductivity is up to 5300W/mK, and higher than carbon nanotube and diamond, under normal temperature, its electronic mobility is more than 15000cm2/Vs, again than CNT (carbon nano-tube) or silicon wafer height, and resistivity only about 10-6 Ω cm, than copper or silver lower, be the material that resistivity is minimum in the world at present.At present, also report that no matter Graphene is directly prepare on copper or nickel, or transfer on other metals, all can provide anti-corrosion protection.Copper coating cultivates single-layer graphene, adopts chemical Vapor deposition process, and slower than naked copper seven times of corrosion meeting, nickel coating cultivates multi-layer graphene, corrodes slower than naked nickel more than 20 times.Single-layer graphene has identical anti-corrosion protection effect, and just as conventional organic coating, but the latter wants thick more than five times.
Summary of the invention
The object of the invention is: a kind of metal anti-corrosive paint with high corrosion resistance is provided, by strictly controlling the consumption of zinc and Graphene, good effect is played to the antirust of metal, metallic corrosion can be slowed down, reduce costs, form uniform passivation layer and corrosion-inhibiting layer in metallic surface simultaneously, make the synchronous inhibition of whole coating, and impart the water-fast, alkaline-resisting of this coating excellence and artificial weathering ageing resistance's antiseptic property.The coating system adopted is aqueous coating system, has the preservative effect of this excellence in the seawater, effectively expands its range of application.
