The passivation solution comprises, in percent by weight: 6-8% of modified organic silicon resin, 22-26% of polyurethane resin, 1-2% of cerium nitrate, 3-5% of ammonium persulfate, 2-4% of sodium chloride, 12-14% of silica gel, 3.5-4.5% of sodium sulfide, 2-4% of sodium dihydrogen phosphate, 6-8% of nitric acid, 0.6-0.8% of bis[3-(triethoxysilyl)propyl]tetrasulfide, and the balance water.
Description
Technical field
The present invention relates to technical field of surface, particularly relate to a kind of aluminum alloy surface passivating solution of substitute chromium passivation.
Background technology
Aluminium is that nature stores one of the abundantest metallic element, due to Aluminum-aluminum alloy have that little, the good heat conduction of proportion and electroconductibility, reflective are strong, the physical and chemical performance that is easy to forming process and excellence, the advantage such as cheap, be widely used in the fields such as telecommunications, household electrical appliances, building, automobile, hot-water heating at present.But aluminium alloy moist, containing the alkaline medium such as industrial gasses, fuel gas and salt solution in use time very easily there is the destruction of the forms such as spot corrosion, crevice corrosion, stress corrosion and corrosion fatigue.
In order to prevent Aluminum-aluminum alloy to be corroded, people generally can process its surface, and chromating process is now widely used method.Chromating process can significantly improve the resistance to corrosion on Aluminum-aluminum alloy surface, this passive film has good sticking power to coating simultaneously, in addition with low cost, thus be widely applied, but chromating treatment solution contains the sexavalent chrome be very harmful to human body and environment, not only can produce pollution in treating processes, and the sexavalent chrome in passive film also will cause processed product to use in the future and discarded time secondary pollution is caused to environment.
Along with people are to the enhancing of environmental protection consciousness, chromic application is subject to strict restriction gradually.On February 13rd, 2003, European Union has issued " waste electronic andelectrical equipment instruction " and " using some Hazardous Substances Directive about restriction in electronic electric equipment ".The former came into force from August 13rd, 2004, and the 10 large classes being to the effect that exported to European Union totally 99 kinds of electronic and electrical equipments reclaim and processing costs will be born by manufacturer oneself; Latter came into force from 1 day July in 2006, and mainly forbid the electronic and electrical equipment selling leaded, mercury, cadmium, sexavalent chrome, poly-6 kinds of objectionable impuritiess such as dibromodiphenyl ether and poly-bromo biphenyl to European Union, this instruction will relate to 8 large classes totally 64 kinds of products.
Research and develop material that is nontoxic or low toxicity imperative with substitute chromium hydrochlorate passivation technology.
Summary of the invention
The object of the invention is to the aluminum alloy surface passivating solution proposing a kind of substitute chromium passivation, this passivating solution is not containing chromic salt, but its passivation effect can reach the anticorrosion effect of chromium passivating.
For reaching this object, the present invention by the following technical solutions:
A kind of aluminum alloy surface passivating solution of substitute chromium passivation, the composition of this passivating solution is by weight percentage: modified organic silicone resin 6-8%, urethane resin 22-26%, cerous nitrate 1-2%, ammonium persulphate 3-5%, sodium-chlor 2-4%, silica gel 12-14%, sodium sulphite 3.5-4.5%, SODIUM PHOSPHATE, MONOBASIC 2-4%, nitric acid 6-8%, two-[3-(triethoxy) silicon propyl group] tetrasulfide 0.6-0.8%, surplus is water.
Preferably, the composition of this passivating solution is by weight percentage: modified organic silicone resin 7%, urethane resin 24%, cerous nitrate 1.5%, ammonium persulphate 4%, sodium-chlor 3%, silica gel 13%, sodium sulphite 4.0%, SODIUM PHOSPHATE, MONOBASIC 3%, nitric acid 7%, two-[3-(triethoxy) silicon propyl group] tetrasulfide 0.7%, surplus is water.
The present invention has following beneficial effect:
The alternative chromium passivating of passivating solution of the present invention, this chromate-free passivating solution passivation Al-alloy products can reach the passivation effect of conventional chromic acid passivation solution, and has the incomparable advantage of chromic acid passivation solution:
(1) nontoxicity.The starting material adopted are generally recognized as safe harmful substances, avoid hexavalent chromium environmental pollution and to the able-bodied infringement of workman, improve production environment.
(2) treatment time is shorter, reaches efficient advantage.
(3) excellent passivation effect can be played at normal temperatures, and produce without sediment, reach the advantage of energy-conserving and environment-protective.
(4) economic benefit and social benefit highly significant.This passivating solution price is relatively cheap, and can be user and save writing for the fund of sewage disposal.
