Abstract
The invention provides a practical nickel-free sealing agent for aluminum alloy anodic oxidation, which is prepared by compounding primary salt sodium acetate, secondary salt cobalt acetate and a penetrant sorbitol in combination with an assistant. The physical state is powder or water. The practical nickel-free sealing agent for aluminum alloy anodic oxidation, provided by the invention, is affordable and non-toxic to the ecological environment, and realizes an equivalent effect as nickel salt sealing; the sealing effect on an organic dyed film (red or yellow) is better than that of a nickel salt sealing agent.
Description
Technical field
The present invention relates to aluminium alloy anode oxide without nickel hole sealing technology field, be specifically related to a kind of aluminium alloy anode oxide practical without nickel hole sealing agent.
Background technology
Since nickel salt hole sealing agent is born, nickeliferous hole sealing agent occupies the inundatory market share in aluminium alloy anode oxide sealing always, it is relatively low that reason is that nickeliferous hole sealing agent possesses sealing of hole leaching (redness or yellow dyes exception), energy consumption fast, simple to operate, that can effectively prevent dyeing film dyestuff when sealing of hole, through sealing of hole anodic oxidation aluminum products properties out, all can reach relevant criterion.Nickel salt hole sealing agent is many to aluminium processing development contribution, but metallic nickel is undisputable fact to the pollution of environment.In addition, nickeliferous liquor of hole-sealing tank is containing a large amount of nickel ions, workers with long time is exposed under this environment, with workpiece Long Term Contact, supersensitivity contact dermatitis, even carcinogenic risk, for this reason use of the multinational nickeliferous hole sealing agent of keeping under strict control of European Union are brought out in existence, and put into effect specially relevant limit standard, as BSEN12472:2005.No matter, from current environmental requirement angle or from social sustainable development angle, nickeliferous hole sealing agent is banned without nickel hole sealing agent will be the firm fact.At present about a lot of without the relevant report of nickel hole sealing technology, but comparative maturity is also successfully realized the few of industrialization practice, as Henkel KGaA is approved in European market without nickel hole sealing agent, this hole sealing agent is to take cobalt salt as main component, but because cobalt salt is expensive and such hole sealing agent energy consumption is high, the overall cost of its industrial application is higher, so unsatisfactory in Chinese Industrialization application.Therefore, developing practical is current and long-range direction without nickel hole sealing technology.
Summary of the invention
For practicality without nickel hole sealing technology blank at home, the object of the present invention is to provide a kind of price material benefit, to ecotope toxicological harmless effect, suitable with nickel salt sealing of hole effect, the aluminium alloy anode oxide that the sealing effect of organic dyeing film (red or yellow) is better than to nickel salt hole sealing agent is practical without nickel hole sealing agent.
Alloy anode of the present invention oxidation is practical without nickel hole sealing agent, take sodium-acetate as main salt, and Cobaltous diacetate is auxiliary salt, and sorbyl alcohol is permeate agent, then is equipped with additive compound and forms.
The described physical condition without nickel hole sealing agent can be pulvis or aqua.
Preferably,
Its composition is configured to by weight percentage: described sodium-acetate 20～30%, described Cobaltous diacetate 0.3～1.0%, described sorbyl alcohol 3～8%, described auxiliary agent 15～20%, water surplus.
During preparation, sodium-acetate, Cobaltous diacetate, sorbyl alcohol, auxiliary agent is water-soluble, stir.
Described auxiliary agent comprises and presses down grey agent, promotor, tensio-active agent, steady toner.
But described grey agent is dextrin.
Described promotor is one or both in boric acid, citric acid.
Described tensio-active agent is one or more in AES (being polyoxyethylenated alcohol sodium sulfate), trolamine and triethanolamine salt.
Described steady toner is one or both in peach gum, balsam.
Described sodium-acetate is one or both in crystal water sodium-acetate, sodium acetate, anhydrous.
Described hole sealing agent work bath parameters is: concentration 10g/L, pH:5.5～6.0, time: 1.0um/min, temperature: 85～90 ℃.
Not only price material benefit of the present invention, to ecotope toxicological harmless effect, suitable with nickel salt sealing of hole effect, and can substantially improve its sealing of hole net effect, make the sealing effect of organic dyeing film (red or yellow) be better than nickel salt hole sealing agent.
Embodiment
The present invention design is: hole sealing agent can be take sodium-acetate as main salt, and Cobaltous diacetate is auxiliary salt, and sorbyl alcohol is permeate agent, then is equipped with auxiliary agent and carries out that science is composite to be formed.Wherein take sodium-acetate as main salt, and it is according to being: sodium-acetate relative low price, and the source of goods is stable; Sodium-acetate is nontoxic, can not destroy ecotope; Sodium-acetate occurs with auxiliary salt identity, and has confirmed to possess certain sealing of hole effect in nickel salt hole sealing agent.Then adding Cobaltous diacetate is auxiliary salt, and sorbyl alcohol is permeate agent, is equipped with auxiliary agent (containing pressing down grey agent, promotor, tensio-active agent, steady toner), further substantially improves its sealing of hole net effect.
The present invention design realizes by following embodiment, aluminum usedly in operating process is same specification 6063 section bars.By specific embodiments of the invention given below, can further understand the present invention, but they not limitation of the invention.Some nonessential improvement and adjustment of for those skilled in the art, according to foregoing invention content, doing, be also considered as dropping in protection scope of the present invention.
