Description
Technical field
The present invention relates to field of metal surface treatment technology, and in particular to a kind of organic without chromium and nickel heavy metal
Passivator.
Background technology
Aluminium alloy is a kind of good heat conduction and conductive metal, good mechanical performance and relative inertness, in electronics, is handed over
It is widely used in many fields such as logical, instrument, aviation and industry.Aluminium alloy is usually used in cooling fin, lamps and lanterns, wind in the electronics industry
Flabellum, electric appliance etc.；Transportation industry is also commonly used for chemical industry container, building materials, print in addition for body of a motor car, label, part etc.
Brush version, billboard, kitchen tools etc..Since reform and opening-up, China's aluminum i ndustry is quickly grown, and has formed collection research and development and processing integrated modern
The aluminum i ndustry system of change；China's aluminium consumption is more than 8,000,000 tons within 2006 simultaneously, it has also become aluminum i ndustry production and consumption in the world
Big country.
Aluminium is a kind of amphoteric metal, but it is also being easy to happen the material of corrosion.Aluminium alloy autoxidation in an atmosphere
Layer protecting film can be generated, but the film is thin and loose porous, destructible.The corrosion of aluminium alloy is spontaneous known to thermodynamic consideration
And the phenomenon that generally existing, corrosion rate depend on the media environment residing for it.Aluminium alloy corrosion rate in different environments
It is different to be primarily due to the corrosion failure factor in different medium for difference.Corrosion rate of the aluminium alloy in atmospheric environment mainly by
The influences such as oxygen, water and atmosphere pollution sulfur dioxide, dust in air；In addition to oxygen, water in by air in industrial environment
Equal influences also suffer from the influence of acidic environment or alkaline environment in industrial production, and acid-base environment can improve the corrosion of aluminium alloy
Rate；In marine environment in addition in by solution water and oxygen influenced also to be influenced by chlorion, a large amount of chlorion is easy broken
The oxidation film of bad aluminum alloy surface so that metallic matrix, which is exposed in corrosive environment, accelerates metal erosion.Aluminium alloy seldom occurs
General corrosion, typically occurs local corrosion, and type of localized corrosion attack mainly has：Stress corrosion, Pitting corrosion, intergranular are rotten
Erosion, galvanic corrosion, crevice corrosion etc..After aluminium alloy corrodes, can all it occur in shape, color and luster and mechanical properties huge
The problems such as big variation, generation pipe leakage, equipment damage and environmental pollution, causes resource and the serious waste of the energy, or even makes
At serious accidents such as fire or explosions so that national economy takes a bath.It is therefore prevented that, mitigate or control aluminium alloy
Corrosion is studied and is protected aluminium alloy with the method for Sciences Economics safety, has ten to the development of the national economy and development
Divide the hot and difficult issue studied in great meaning, and current technical field of aluminum alloy surface treatment.
Using being most simply and effectively passivation of metal surfaces treatment technology in corrosion of aluminium alloy protective treatment at present, actually
Exactly metal and Korrosionsmedium are separated by generating one layer of passivating film, prevent Korrosionsmedium penetrating into metallic matrix to drop
Low metal corrosion rate.The technical operation is convenient, it is simple to save the energy, equipment, has been widely used in electronic equipment, household
The numerous areas such as electric appliance, construction material, packing business.It, usually will be with other protective layers (as painted when passivating film is used for metal protection
Deng) it is used together the polynary protection system of composition, enhance the anti-corrosion capability of metal.The effect of passivating film is mainly reflected in two at this time
Aspect：1) enhancing protecting metallic surface layer keeps protective layer not easily to fall off with the binding force of metallic matrix；2) metal erosion is prevented
Extension can stop the extension of corrosion when passivating film when the damaged or medium that is corroded penetrates locally occurs for protecting metallic surface layer.
Traditional passivation treatment technology is chromating.Chromate is as outstanding corrosion between past more than 100 years
Inhibitor is widely used in metal finishing industry.Chromating technique is very ripe, chromate treated metal
Corrosion resistance of surface is very good, and specious, of low cost, easy to use, has obtained everybody and has generally accepted and be widely used.But
It is that can generate fatal threat to biology and human body since Cr VI has carcinogenicity.Cr VI is that a kind of toxicity is very big simultaneously
Substance, it seriously pollutes environment, and Long Term Contact can cause number of people pain, stupor, rhinitis, nasal perforation, skin ulcer and cause each
The symptoms such as kind canceration, it is very harmful to people's health.Therefore on 2 13rd, 2003, European Union has promulgated that WEEE and ROHS refer to
Enable, it is specified that from 1 day July in 2006, it is new into EU market electronic apparatus must not contain the lead of the requirement that is above standard, mercury, cadmium,
Six kinds of Cr VI, poly- dibromodiphenyl ether (PBDE) and poly- bromo biphenyl (PBB) harmful substances.
Cr VI has carcinogenicity, and can cause environmental pollution, in addition European Union uses stringent limitation to Cr VI, bans
Possessing the chromic acid salt treatment process of one-hundred-year history becomes the inexorable trend of metal finishing industry, therefore develops non-toxic or low-toxic
Non-chromium inactivating technique replace chromating technique extremely urgent, and that walks environment sustainable development road must go it
Diameter.Emerging chromium-free deactivation technology is broadly divided into three classes at present, respectively inorganic passivation, organic passivation and composite passivated.At present
Inorganic passivating technique or organic passivation technology is used alone, corrosion resistance is unable to reach chromium passivating effect.And existing nothing
The film-formation result of chromium passivating technology is unstable, and it is poor with the associativity of other coating to exist, and binding ability is not strong, and durability is bad,
The problems such as being easy blistering, falling off.
