| titleOfInvention | A kind of chromium-free passivation liquid for galvanized sheet, aluminium and copper alloy surface process |
| abstract | The invention discloses a kind of chromium-free passivation liquid for galvanized sheet, aluminium and copper alloy surface process, belong to technical field of metal material surface treatment.The mass percent of this chromium-free passivation liquid is composed as follows: two (trolamine) metatitanic acid diisopropyl ester 0.5-15%, Di(dioctylpyrophosphato) ethylene titanate 0.5-15%, trolamine 0.1-2%, ammonium acetate 0.1-5%, nano silicon oxide 0.01-2%, hydrofluotitanic acid 0.1-5%, ammonium meta-vanadate 0.01-5%, excess water.The component of chromium-free passivation liquid of the present invention is simple, product environmental protection and before using without the need to pre-treatment, cost is low, poisonous chromating technique can be replaced, can be used for galvanized sheet, aluminium and copper alloy metal plate surface passivating treatment, gained passive film even compact, tack are good, solidity to corrosion is strong, have excellent resistance to fingerprint, solvent resistant, alkaline-resisting and coating performance. |
