Description

Be used for metal pretreated surface to form the regulator solution and the control method of phosphate layer

The present invention relates to a kind of treatment solution and surface modulation method that is used for surface modulation, form phosphate layer in order to the ground of chemical on the metallic surface, can be applicable to such as steel, steel plate galvanized, aluminium and magnesium alloy etc.,, the phosphate crystal in the phosphate layer is attenuated to promote and to quicken chemical reaction.

Recently, a kind of demand that forms fine and closely woven phosphate crystal in phosphate layer is arranged,, and reduce the friction of this metal under cold operation in order to the erosion resistance after the improvement coating.Therefore use the surface modulation method earlier before often forming phosphate layer,, and make the nucleus that is suitable for producing fine and closely woven phosphate crystal with the activated metal surface in chemical ground.Hereinafter illustration is commonly used to obtain the method for fine and closely woven phosphate crystal.The phosphoric acid salt series of strata produce according to following steps.(1) removes fatty oil (2) washing (multiple-step form) (3) surface modulation (4) chemical ground and form phosphate layer (5) washing (multiple-step form) (6) rinsing in pure water.

The surface modulation method is suitable for making phosphate crystal to become fine and closely woven.The chemically composited material of Shi Yonging is disclosed in the United States Patent (USP) No. 2874081, No. 2322349 and No. 2310239 traditionally, wherein shows a kind of regulator solution, contains titanium, pyrophosphate ion, former phosphate ion and sodium ion etc.This matrix material is called Ztel's salt (Jernstedt salt), and the aqueous solution of this matrix material contains titanium ion and titanium colloid.

When metal impregnation sprays in aforementioned regulator solution or with aforementioned regulator solution, this metallic surface absorption titanium colloid.Adsorbed titanium colloid will become nucleus in the process of chemical ground formation phosphate layer, promote chemical reaction, and produce fine and closely woven crystallization.At present, the surface modulation matrix material of all industrial application all uses Ztel's salt (Jernstedt salt).Yet the industrial application of Ztel's salt (Jernstedt salt) produces problem miscellaneous.

First problem is that this surface modulation solution is degraded with the process of work time.Apply when using surface modulation solution always, at making phosphate crystal become fine and closely woven immediately after this aqueous solution of preparation, this salt has shown suitable obvious effects.But after the preparation a few days, no matter, all lose this kind effect whether through using, and the chap because of the titanium colloid condense in the regulator solution of the phosphate crystal of gained.

Hereat, JP63-76883A has disclosed a kind of method, and this surface modulation liquid of a configuration part also adds new surface modulation liquid continuously, periodic measurement and make titanium colloidal mean diameter keep enough little values.Though this kind method can be controlled this surface modulation liquid quantitatively, this part surface regulator solution need be handled to keep this kind effect.Therefore, this method need dispose a large amount of these surface modulation liquid and have jumbo water configuration device.

Second problem has very big relation for the effect of this surface modulation liquid and life-span and quality in order to the water for preparing.Usually, use tap water to prepare this surface modulation liquid.But known tap water contains positively charged ion such as calcium, magnesium etc. usually.And cationic content is decided on the water source.In the case, the known titanium colloid does not precipitate to keep dispersion because of the electric repulsion of the electric charge in the negatively charged ion.Therefore, if tap water contains excessive cationic composition, then the titanium colloid can be neutralized by the cationic composition, and loses its repulsive force so that condense and precipitate.

Someone is set forth in the phosphoric acid salt of interpolation condensation in this surface modulation liquid such as pyrophosphate salt, with the cationic composition of blockading, and keeps titanium colloidal stability.But when adding excessive condensed phosphate in this surface modulation liquid, may produce inert coating because of the reaction of the metallic surface in this condensed phosphoric acid and this regulator solution, the process of formation phosphate layer has problems with making in the subsequent disposal on metal chemical.The place of containing excessive calcium or magnesium in tap water needs to use pure water to make this regulator solution, causes shortcoming economically.

The 3rd problem is temperature and the pH when applying.For example, the titanium colloid promptly condenses in the scope that is higher than 35 ℃ temperature and exceeds pH8.0-9.5, forfeiture surface modulation effect.Therefore, Chang Yong surface modulation liquid must use in the specified temp and the pH scope of close limit.Therefore, can't be as making as the single-liquid type this surface modulation liquid produce cleaning effect.

The miniaturization that the 4th problem is phosphate crystal is restricted.The miniaturization of phosphate crystal forms from the titanium colloid nucleus that is adsorbed on this metallic surface, helps the detailed-oriented of phosphate crystal.Therefore, the titanium colloid that adsorbs on the metallic surface the more can obtain the fine and closely woven phosphate crystal of healing.

In order to solve this problem, be easy to expect that suggestion increases the titanium colloidal number in the regulator solution.But density is higher, and the frequency of bump is higher each other in this regulator solution for the titanium colloid, causes condensing and sedimentation the more.The titanium colloidal upper limit of using is lower than 100ppm at present, can't use higher density titanium colloidal regulator solution.

JP56-156778A and JP57-23066A have disclosed and have a kind ofly depressed the soluble phosphatic suspension that will contain divalence or trivalent metal and spray method on this steel face in adding.But only depress when spraying this suspension just display effect in adding, so method can't be applied to the general control method that makes this metal impregnation or spray this regulator solution.

JP40-1095B2 has disclosed another kind of surface modulation method, steel plate galvanized be impregnated in the soluble phosphatic suspension of divalence or trivalent metal.But the application example of this method only is confined to steel plate galvanized, and needs to use at least up to the soluble phosphoric acid salt of the high-density of 30 grams per liters.

Illustrated as preamble, the method relevant with Ztel's salt (Jernstedt salt) presented so various problem.Yet, the method that can replace this Ztel's method (Jernstedtmethod) is not arranged at present yet.

(1) in conjunction with the method for degreasing and surface modulation

(2) chemical ground forms phosphate layer

(3) washing (multiple-step form)

(4) rinsing in pure water

The phosphate particle of divalence or trivalent metal and acceleration composition are neccessary composition of the present invention.As mentioned before, purpose of the present invention is that a kind of surface modulation liquid is provided, and it activated this metallic surface before forming phosphate layer, and produced the employed nucleus of phosphorus supply hydrochlorate crystalline deposit.People such as present inventor find, phosphate particle with the divalence of preferable diameter or trivalent metal is when preferable content, be adsorbed in and await helping to produce the nucleus that the crystallization of phosphorus supply silicate layer is used, and quickening the formation of phosphate layer with on the metallic surface of containing the aqueous solution processing of quickening composition.

The phosphate particle of divalence of the present invention or trivalent metal is a solid and soluble.Yet, chemically, they be with in order to form the similar composition of chemical substance of phosphate layer, also chemically be similar to formed phosphate layer.They continue in the dipping bath even the part of this regulator solution is inserted the solution that is equipped with in order to form phosphate layer afterwards for not having negative impact in order to the solution that forms phosphate layer, also can not have a negative impact for this phosphate layer.The phosphate particle of divalence of the present invention or trivalent metal has for example following.Zn ₃(PO ₄) ₂, Zn ₂Fe (PO ₄) ₂, Zn ₂Ni (PO ₄) ₂, Ni ₃(PO ₄) ₂, Zn ₂Mn (PO ₄) ₂, Mn ₃(PO ₄) ₂, Mn ₂Fe (PO ₄) ₂, Ca ₃(PO ₄) ₂, Zn ₂Ca (PO ₄) ₂, FePO ₄, AlPO ₄, CoPO ₄, Co ₃(PO ₄) ₂And the hydrate of this compounds.

The increase of sedimentary crystallization number diminished when phosphate layer crystalline particle diameter began with the work reaction.Because when adjacent crystallization contacted with each other, crystallization promptly stopped growing.And the crystallization number that reacts when beginning is higher, and the knot intergranular is apart from littler, so this metallic surface can be covered by less crystallization in the short period.Therefore, for the thinner phosphate crystal of precipitation in the short period of time, be preferable over and form the more nucleus of phosphate layer elder generation's manufacturing before.

With regard to the viewpoint in stably being scattered in this aqueous solution, the phosphatic particle diameter of divalence of the present invention or trivalent metal is preferably less than 5 microns.Even may contain diameter in the regulator solution of the present invention greater than 5 microns the divalence or the phosphoric acid salt of trivalent metal, but when this liquid also contain capacity less than 5 microns phosphate particle the time, do not destroy effect of the present invention.

The phosphate particle of divalence of the present invention or trivalent metal itself also has the sedimentary effect of promotion.Promptly, the phosphate particle of this divalence or trivalent metal can be adsorbed on this metallic surface in regulate process, and wherein some itself is dissolvable in water in the phosphate layer formation bath of subsequent step, near the metallic surface, provide phosphate component, and significantly promote the precipitation of phosphate layer this phosphate layer.

Ideally, divalence or trivalent metal phosphate particle total amount are between 0.001～30 grams per liter.When the phosphate particle total amount of divalence or trivalent metal is lower than 0.001 grams per liter, the phosphate particle amount that is adsorbed in divalence on the metallic surface or trivalent metal reduces, and can't promote the precipitation of phosphate crystal, and more a spot of particle also can't promote this chemical reaction.

When the phosphate particle amount of divalence or trivalent metal is higher than 30 grams per liters, only produce disadvantageous cost factor, and can't obtain further to promote again the effect of phosphatic formation.
