Abstract
Intercalation Zn-Al alloy powder and its zinc-aluminium of preparation collaboration anticorrosive paint and method, the intercalation Zn-Al alloy powder are made of following methods: (1) mixing zinc chloride molten-salt electrolysis liquid and aluminium chloride molten-salt electrolysis liquid, stirring obtains fused salt mixt electrolyte；(2) using copper sheet as cathode, graphite is anode, the electro-deposition in fused salt mixt electrolyte；(3) copper sheet is taken out, is rinsed, deposit cleaning, filtering, vacuum drying obtain intercalation Zn-Al alloy powder.The zinc-aluminium collaboration anticorrosive paint includes the intercalation Zn-Al alloy powder, organic solvent, anti-settling agent and electroconductive resin.The preparation method is to mix the intercalation Zn-Al alloy powder with organic solvent, and anti-settling agent is added in stirring, adds electroconductive resin,.The alloy pattern and microalloying degree of intercalation allumen of the present invention are controllable；It is applied to zinc-aluminium collaboration anticorrosive paint, more existing galvanizing by dipping, zinc aluminum anticorrosive paint antiseptic property are more preferable；The method of the present invention low energy consumption, low pollution.
Description
Technical field
The present invention relates to a kind of Zn-Al alloy powder and its anticorrosive paints and method of preparation, and in particular to a kind of intercalation zinc
Al alloy powder and its zinc-aluminium instead of galvanizing by dipping of preparation cooperate with anticorrosive paint and method.
Background technique
Fused salt electro-deposition prepares electro-deposition coating, is in the inorganic salts, organic salt or ionic liquid of melting, using outer
The voltage and current added, and control current density, obtain a kind of preparation process of the coat of metal or alloy powder on substrate,
The problems such as aquation, hydrolysis and liberation of hydrogen is not present in fused salt electrodeposition process, pollution-free, has been widely used at present.Fused salt electro-deposition
Method is used to plate earliest alclad on steel substrate, and because plated layer compact, thickness is controllable, low energy consumption due to rapid proliferation, then grind
Study carefully discovery to form alloy between iron and aluminium during the deposition process and realize close attachment by the metallic bond in alloy, then theoretically
It only need to change substrate, fused salt electrodeposition process can be used to obtain refined metals powder or prepare alloying pellet.From last century 80
It is gradually mature using fused salt electrodeposition process preparation nickel aluminum alloy, zinc/ferroalloy technique from age, it is 2007 or so, external
Zinc/Al alloy powder is prepared.But alloy is prepared using fused salt electrodeposition process, allotment gold can only be passed through before the deposition
Belong to molten-salt electrolysis liquid concentration to control the content of each metal in alloy, the metal proportion being unable to accurately control in alloy.In addition, molten
The powder of salt electrodeposition process preparation is in prong shape more, and heap poststack bedding void is larger, it is difficult to play the side such as anti-corrosion, anti-halobios adhersion
The effectiveness in face.
In the heavily contaminated environment that heavy industry pollution and adjoint extreme natural environment are formed, Steel structure equipment corrosion is fast
Speed, annual therefore caused loss have been more than the summation of the loss as caused by the disasters such as fire, earthquake.Conventional hot-dip zinc produces
Product have both cathodic protection and shielding action, and Wear resistance and Anti corrosion is good, easily weld, and adhesion property is excellent, and surface-brightening is beautiful, thus quilt
The industries such as traffic, building, electric power, the energy, automobile, petrochemical industry, household electrical appliances are widely used in, are most widely used in global range
Steel structure anti-corrosion technology.
Though hot dip galvanized product has longer service life and lower validity period maintenance cost, the limitation of itself
Property it is also same obvious.For example, (1) galvanizing by dipping energy consumption is high, 500 DEG C or more need to be heated to, therefore process not can avoid oxygen
The defect that rate is high, porosity is high, causes use process point corrosion easily occur, leaves security risk；(2) galvanizing by dipping is difficult to
Thickness of coating is controlled, the processing of precision component is not used to；(3) surface treatment of hot dip galvanized product requires high, and technique is cumbersome,
Both production cycle and the cost for having improved galvanizing by dipping are also easily introduced impurity and cause potential hazard.In addition, galvanizing by dipping produced
Cheng Zhonghui escapes plurality of heavy metal dust, strong acid steam, and welding endangers operator's health, and country has put into effect phase thus
Pass policy limits this production technology of galvanizing by dipping.Therefore, for various comprehensive to performance, production technology, policy, environment etc.
Conjunction is considered, and galvanizing by dipping is not the appropriate method for being anticorrosion of steel structure.
Anticorrosive coating is one of the most effective means for alleviating corrosion, easy to use, cheap.Anticorrosive coating kind
Various, the most excellent with cold-applied zinc, cold-applied zinc dry film Zn content is higher than 96%, and corrosion resistance, heat resistance, durability are all very prominent
Out, gray but after cold-applied zinc brushing, does not have the metallic luster of the bright silver of zinc.And such as a kind of water of CN103952026 A(
Dissolubility zinc aluminum anticorrosive paint and preparation method thereof), a kind of chromium-free zinc aluminum anticorrosive paint of CN101899254 A(and preparation method),
High watersoluble modified anticorrosive paint of intercalation of CN105820677 A(a kind of nanoscale environmental protection and preparation method thereof) etc. patents and its turn
The product of change then improves the appearance of anticorrosive paint, but this measure sacrifice by way of introducing bright metal, reducing zinc content
Part antiseptic property.This kind of zinc aluminum anticorrosive paint is only added into resin using zinc, aluminium as filler by a certain percentage, due to zinc
Powder, the partial size of aluminium powder, shape are different, gap easily occur between particle after the drying, it is difficult to guarantee the consistency of dry coating, also easily
The phenomenon that causing coating shedding.Simultaneously as the corrosion potential of zinc-aluminium is different, corrosion rate is different, it is also difficult to realize zinc-aluminium
Collaboration antisepsis.
