Abstract
The invention provides a kind of Zinc-calcium phosphide solution used for no washing before painting under normal temp, its composition weight proportioning is zinc, calcium salt 0.2-4%, the activator 0.7-4% that phosphoric acid salt, oleate etc. and organic acid are formed, passivator 0.2-1.5% such as molybdate, acetate, phosphoric acid salt, additive such as molysite, ferrous salt 0.02-0.08%, water 90-99%.This phosphatization liquid good stability, sediment are few, can use repeatedly and not lose efficacy, and do not discharge, no obnoxious flavour produces, one step was finished table accent, phosphatization, passivation whole process, and do not wash, even film layer, continuously, fine and close, can be used for the bonderizing before iron and steel and the goods application thereof.
Description
The present invention relates to a kind of phosphatization liquid, particularly relate to a kind of normal temperature and do not wash the preceding zinc calcium phosphorization liquid of lacquer.
Before phosphatization liquid is widely used in iron and steel and goods application thereof, for example baking vanish, spray paint, the bonderizing before the electrostatic plastic spraying, electrophoretic enamelling etc., also can be used for antirust between the metal manufacturing procedure.The kind of phosphatization liquid is a lot of at present, wherein Zinc-calcium series phosphatating liquid is a kind of phosphatization effect phosphatization liquid preferably, Chinese patent application 86100516A discloses a kind of Zinc-calcium series phosphatating liquid, and it consists of primary zinc phosphate: nitrocalcite: phosphoric acid: nickelous nitrate: citric acid or gluconic acid: the sodium salt of citric acid or gluconic acid or calcium salt: Sodium Fluoride: water is 2.5-3.5: 4.9-8.4: 0.5-1: 0.02-0.16: 0.015-0.06: 0.002-0.04: 0.002-0.08: 4-60.Contain objectionable impuritiess such as nitrate radical and fluorion in this phosphatization liquid, and owing to contain the strong acid root, will wash after the phosphatization, the phosphatization temperature height is generally 50-75 ℃, and phosphatization liquid sediment is many.
The objective of the invention is to overcome above-mentioned shortcoming, a kind of nitrate radical, fluorion etc. of not containing are provided, can once finish the Zinc-calcium phosphide solution used for no washing before painting under normal temp of table accent, phosphatization, passivation whole process at normal temperatures.
Normal temperature of the present invention is not washed its component of zinc calcium phosphorization liquid and is comprised membrane-forming agent 0.2-4%(weight), activator 0.7-4%(weight), passivator 0.2-1.5%(weight), additive 0.02-0.08%(weight), water 90-99%(weight).Wherein membrane-forming agent is the mixture of one or more zinc salts and calcium salt in phosphoric acid zinc salt, calcium phosphate salt, lightweight carbonic acid zinc salt, the light calcium carbonate salt, zinc: calcium is 1: 0.3-1.2, with zinc is major-minorly to be tied to form film with calcium, can improve the rete crystal structure, improve film adhesion, make the rete densification, evenly, corrosion strength is strong.Activator is mineral acid or salt, as one or more and organic acid in phosphoric acid titanium salt, sodium phosphate salt, phosphoric acid and the oleate etc., as one or more the mixture in vinylformic acid, tartrate, citric acid and the gluconic acid etc., its effect is to quicken phosphatization speed, crystal grain thinning forms the fine and close film that hangs down the hole.Do not contain SODIUMNITRATE, Sodium Nitrite and the fluorion etc. of strong toxicity in the activator of the present invention, use safer.Passivator is at least a in molybdate, acetate and the phosphoric acid salt, its effect be seal effectively become micropore in the phosphatize phosphate coat, make the even film layer densification, improve slushing oil.Additive, be not contain at least a in the molysite of strong acid root or the ferrous salt, its effect is in order to keep the proper metal ion degree of depth, to quicken phosphatization, making rete careful.Nontoxic with water as solvent, do not fire, economy.
The pH value of Zinc-calcium phosphide solution used for no washing before painting under normal temp of the present invention is controlled at 0.5-3.5, the total acidity height, and the phosphatize phosphate coat crystallization is careful, but too high meeting makes phosphatize phosphate coat too thin, crosses low thickness, coarse.
The advantage of Zinc-calcium phosphide solution used for no washing before painting under normal temp of the present invention is:
1, phosphatization liquid good stability, never degenerate, do not discharge, can use repeatedly, only need press the additional new liquid of actual consumption.
2, nontoxic, the no stink of phosphatization liquid, no obnoxious flavour produce, and do not have sediment substantially, do not wash, and be free from environmental pollution.
3, the phosphatize phosphate coat densification that forms after the phosphatization, even, firm, flexible good, thickness is suitable, and preservative property are strong, increase the bonding force of coating and metallic matrix, can improve the gloss of coating to a certain extent and save coating.
4, use this phosphatization liquid that seven procedures of conventional phosphatization are kept to twice (being phosphatization, drying), can finish the phosphatization whole process in a groove, technology is simple, and is easy to operate.
5, phosphatization liquid comprehensive cost is low, can finish the phosphatization whole process apace in a trough, has improved phosphatization efficient.
Zinc-calcium phosphide solution used for no washing before painting under normal temp of the present invention can be used for the lacquer pre-treatment of different shape iron and steel and goods thereof, and is supporting with electrophoretic enamelling, plastic-blasting, baking vanish, coating process such as spray paint.
