Abstract
The present invention adopts the innovation scheme, a kind of iron and steel surface painting preprocessing liquor-one step phosphorus liquid that contains tannic acid is provided, be applicable to straight carbon steel, low alloy steel, the Coating Pretreatment of iron member, the steel and iron member that adopts the present invention's one one step phosphorus liquor to handle, can a step finish oil removing at 7～30 minutes, rust cleaning, phosphatization, the passivation whole process, and at the surperficial corrosion prevention film that forms 4～9 μ of steel part, the copper sulfate test rating is 3～14 minutes, soak 8 hours no rusty stains with 3% sodium chloride solution, indoor storage a year and a half non-corroding, reach one-level with PASS, treatment process adopts drill traverse, spray and brush and all can.
Description
The present invention relates to iron and steel surface painting preprocessing liquor, particularly a step is finished an one step phosphorus liquor of oil removing, rust cleaning, phosphatization, passivation, is applicable to the finish coatings pre-treatment of steel and iron member such as straight carbon steel, low alloy steel, cast iron.
The protective coating of steel and iron member relates to every field such as metallurgy, building, machinery, shipbuilding, oil, chemical industry, railway, water conservancy, electric power, light industry and national defense industry, and the protective coating technology that improves steel and iron member has become many departments problem anxious to be solved.The useful life of the erosion shield of steel surface depends on the preconditioning technique before the application, selects the pretreating scheme of excellent property most important.The preconditioning technique of phosphorization technology before as coating iron and steel member is very general, and it has anticorrosion, lubricated, insulation and increases characteristic such as PASS.At present, domestic many producers are still using the multistep phosphating process, because complex process, processing cost height, seriously polluted and progressively replaced by a step phosphating process.One step phosphating process can be finished oil removing, rust cleaning, phosphatization, one step of passivation, but the steel and iron member rust-proof effect that an existing step phosphating process is handled is poor and the powder that whitens, influence adhesive force of coatings, anticorrosion ability is poor, the copper-bath test rating is mostly below 60 seconds, indoor storage had corrosion in 2～4 months, and contain objectionable impuritiess such as nitrite and dichromate mostly, seriously polluted.Study a kind of favorable rust preventing effect, to pollute the low one step phosphorus liquor of little processing cost very necessary.
31 DC series metal surface treatment liquids at above-mentioned existing problems development of Ministry of Astronautics Industry are made up of degreaser, rust-preventive agent, phosphorization agent, passivator, do not contain objectionable impuritiess such as nitrite, dichromate, a step is finished oil removing, rust cleaning, phosphatization, passivation all processes.Treated steel and iron member copper sulfate test rating is about 30 seconds, soaks 2 hours no rusty stains with 3% sodium chloride solution at 25 ℃, reaches 2 grades with PASS, in air, deposit ten surplus day non-corrosive.
The objective of the invention is to adopt the innovation scheme, a kind of iron and steel surface painting preprocessing liquor that contains tannic acid-an one step phosphorus liquor of excellent property is provided.
The present invention is made up of degreaser, rust remover, phosphorization agent, passivator, and adding contains the material of tannic acid (as tannin, tannin extract ...) make it contain 0.01～25%(weight %) and tannic acid, can one the step finish oil removing, rust cleaning, phosphatization, passivation all processes.The blue or green brown corrosion prevention film that treated steel and iron member surface forms with matrix and is connected as a single entity, is evenly distributed, Zu Zhi Cause is close, crystal grain is thin.
The weight of the present invention's one one step phosphorus liquor optimum formula consists of: phosphoric acid 5～48%, tannic acid 0.01～25%, zinc oxide or zinc phosphate 0.02～7%, amine molybdate or Sodium orthomolybdate 0.001～4%, sulphur urine or urotropine 0.01～4%, sodium alkyl benzene sulfonate or alkyl sodium sulfonate or OP～10 emulsifying agents 0.01～5%, tertiary sodium phosphate or trisodium phosphate 0.01～5%, all the other are water.
The present invention also can add the material that contains tannin in right amount to existing many one step phosphorus liquors and adjust except that adopting above-mentioned optimum formula, can improve the over-all properties of phosphatize phosphate coat.
The present invention's one step phosphating process flow process is as follows:
Pending steel and iron member immersion is filled in the groove of the present invention's one one step phosphorus liquor, in 10～90 ℃ of temperature ranges, soak and to remove whole rusty stains in 1～8 minute, soak and to finish oil removing, rust cleaning, phosphatization, passivation all processes in 7～30 minutes, take out seasoning at room temperature then and got final product in 5～24 hours.
The present invention's one step phosphating process also can adopt and spray and brushing except that drill traverse.
The present invention's one one step phosphorus liquor is through regulating renewable use.
The present invention uses tannic acid in iron and steel surface painting preprocessing liquor-an one step phosphorus liquor, makes the over-all properties of an one step phosphorus liquor obtain obviously to improve.The steel and iron member surface of adopting the present invention's one one step phosphorus liquor to handle forms the corrosion prevention film of 4～9 μ, and the copper sulfate test rating is 3～14 minutes.Soak 8 hours no rusty stains with 3% sodium chloride solution at 25 ℃.Indoor storage above non-corroding of a year and a half, the no white powder in surface, the sticking power of film and paint reaches one-level.
The present invention's one one step phosphorus liquor also is applicable to the surface anticorrosion brushing liquid of stock's steel; Also be applicable to need not the painted steel container anticorrosion masking liquid; Also be applicable to the removing of stocking iron scale.
