Abstract
The invention relates to a high temperature resistant metal passivator, wherein the main raw materials thereof comprise the following components in percentage by mass: 93-95 percent of water, 1-2 percent of phosphate, 0.5-1 percent of accelerant, 0.05-0.1 percent of surfactant and 3-4 percent of high temperature resistant passivation component. The phosphate is one of disodium hydrogen phosphate, monobasic sodium phosphate and sodium phosphate; the accelerant is one of cerium carbonate dehydrate, cerium nitrate and cerous nitrate; the surfactant is one or the mixed compound of OP-10, TX-100 and NP-5, and the mass ratio of the mixed compound is 2:1:1; the high temperature resistant passivation component is one of zirconyl chloride and zirconyl nitrate; and the passivator is regulated through a phosphoric acid, and the pH value thereof is 3.0-5.0. A layer of uniform and compact passivation film is rapidly formed on the surface of a steel material processed through the high temperature resistant metal passivator, the film has strong corrosion-resistant performance, and a passivated steel part has good corrosion-resistant performance whether blow-dried or dried at the temperature of 200-250 DEG C.
Description
Technical field
The present invention relates to a kind of passivator, particularly a kind of high temperature resistant metal passivator.
Background technology
The steel material surface spraying is a kind of common technology, sprays preceding sticking power for raising coating and metallic matrix, prevents surface corrosion, just must take phosphatization, deactivating process for the treatment of.
At present, the passivator that is used for the iron and steel Passivation Treatment generally has three classes, that is: chromic salt, molybdate and organic passivates.
Though make low, the corrosion resistance and good of passivator cost with chromic salt, its toxicity height, and easily carcinogenic, great pollution is caused to environment in the discharging back, is difficult to administer, so the use of chromic salt is subjected to strict restriction.
The organic passivates price is expensive, and can give out various irritating smells, and long-term contact has carcinogenesis, and passivator is easy to generate bacterium, water body is gone bad and the generation problem of environmental pollution.
Molybdate is a kind of effective film forming accelerating and sustained release dosage, and is with high costs because of it, and corrosion resistance nature makes most of enterprises not accept not as good as chromic salt after the passivation.
Simultaneously, because steel-iron components is after phosphatization, passivation, powder spraying needs to carry out under 200 ℃ or above temperature condition, adopts the production line of automatic spraying, need make the passivation workpiece dry under 200 ℃ or above temperature condition before spraying, cause the steel-iron components surface can partial corrosion.
Therefore, seek a kind of do not contain chromic salt, organic passivation composition and can resistant to elevated temperatures passivator treatment process before for metal spraying significant.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of and can at high temperature avoid being corroded after making the iron and steel passivation, be mainly used in the passivation technology after iron and steel parts is shaped, and can be high temperature resistant, do not bring the high temperature resistant metal passivator of environmental pollution.
The objective of the invention is to be achieved through the following technical solutions:
A kind of high temperature resistant metal passivator, the mass percent of its each component of main raw material is:
Water 93～95%,
Phosphoric acid salt 1～2%,
Promotor 0.5～1%,
Tensio-active agent 0.05～0.1%,
High temperature resistant passivation composition 3～4%.
Described phosphoric acid salt is a kind of in Sodium phosphate dibasic, SODIUM PHOSPHATE, MONOBASIC, the sodium phosphate.
Described promotor is a kind of in the inferior cerium of two hydration carbonic acid, cerous nitrate, the cerous nitrate.
Described tensio-active agent is a kind of among OP-10, TX-100 and the NP-5.
Described tensio-active agent is the mixing compound of OP-10, TX-100 and NP-5, and the mass ratio of described mixing compound is 2: 1: 1.
Described high temperature resistant passivation composition is a kind of in zirconyl chloride, the Zircosol ZN.
Described passivator is regulated with phosphoric acid, and its pH value is 3.0～5.0.
The present invention can reach following beneficial effect after adopting technique scheme:
1, performance is good.Through the steel that the present invention handles, the surface forms the passive film of one deck even compact fast, and this film corrosion resistance nature is strong, no matter the steel-iron components after transpassivation is to dry up, still dries under 200～250 ℃ of temperature condition, and excellent corrosion resisting performance is all arranged.
2, energy-conservation.Owing to added a spot of nonionogenic tenside among the present invention, greatly reduced the surface tension of solution, make the passivating solution that remains in steel surface in the extremely short time, to come off, can effectively reduce water for cleaning.
3, environmental protection.The present invention is nontoxic, with low cost, preparation is simple, and the steel-iron components after the passivation satisfies European ROHS command request.
4, economic benefit is wide.The present invention has overcome the defective of prior art, has solved problems such as energy consumption height in the prior art, passivation effect be undesirable, has the wide society economic benefit.
