Description
Technical field
The invention belongs to aluminium shape surface processing technology field, more particularly, relate to a kind of aluminium section bar encapsulant and preparation method thereof, application and methods for using them.
Background technology
Anodic oxidation is as Al and Alalloy surface applications the most a kind for the treatment of technology, the corrosion resisting property of Aluminum-aluminum alloy can be improved significantly, improve Aluminum-aluminum alloy surface hardness and wear resistance. closing is anodised a kind of post-treating method, improve the corrosive required technique of anode oxide film, it can also prevent dyestuff from fading simultaneously, improves the photostabilization of dyeing film.Anodised closing process is often classified differently: according to the composition of confining liquid, closure temperature and Seal property, the encapsulant of commercial is generally made up of Multiple components, they play a part different, and there is synergy to closed process and anti-corrosion capability, in closed process, in fenestra, different reactions occurs simultaneously, concerning composite encapsulant, Seal property is quite complicated.At present, the equal fluoride ion of cold sealing agent that most section bar factory of China is used, although sealing process can be played at a lower temperature, but actually operating gets up to have many unfavorable factors, first chemical examination accurately and strict control is needed, simultaneously very high to water quality requirement, and production cost is higher.
If Chinese Patent Application No. is 200810120737.1, publication number is that the patent application document of CN 101665970 A discloses a kind of Al and Alalloy anode oxide film normal-temperature sealer, comprises following component and concentration proportioning: Ni
2+0.8 ~ 1.3g/L, F
-0.4 ~ 0.8g/L, trolamine 0.1 ~ 5.0g/L, hexamethylenetetramine 0.1 ~ 1.0g/L, sodium laurylsulfonate 0.001 ~ 0.1g/L, pollen inhibitor 0.01 ~ 2.0g/L, all the other are water.The use of fluorine-containing encapsulant can to environment, do not meet the requirement of national environmental protection, and the ash that may produce other form closed by nickelous fluoride, this ash mainly to change into the katalysis in oxyhydroxide at aluminum oxide due to nickelous fluoride, pH change and excessive fluoride ion or nickel ion cause, therefore fluorine-containing encapsulant in use strictly will control the pH value, temperature, nickel ion, fluorinion concentration etc. of lock solution, and complex operation, production cost is high.Chinese Patent Application No. is 94111540.2, publication date is that the patent application document on June 26th, 1996 discloses a kind of aluminum and its alloy low temperature quick sealer and closing process, this encapsulant is primarily of metal-salt I, closed stablity agent II and closed promotor III and water composition, feature is that pH value can adjust between 6.3 to 8.4 and solution is not muddy, and envelope thick film can be closed at 20 more than μ, metal-salt I is vitriol or the acetate of nickel or cobalt; Closed stablity agent II is that one or more and the cobalt salt in Monoethanolamine MEA BASF, diethanolamine, trolamine is mixed to get; Closing promotor III is six first tetramines, polyoxyethylene glycol, p-aminophenol, organic phosphonate, tween-80 and water form, and this sealant components is too complicated, and containing gas chromatography, the waste water that later stage produces not easily processes, big for environment pollution and have injury to human body in use procedure.Therefore, need to study a kind of actually operating easy, low to water quality requirement, do not play pollen and the low encapsulant of production cost.
