Abstract

The invention provides a thick rust filled rust treatment solution and a preparation method thereof. The treatment solution comprises the following components in mass percentage: 0.4%-0.6% of tannic acid, 0.4%-0.6% of phytic acid, 4.5%-5.5% of phosphoric acid, 0.8%-1.2% of oxalic acid, 1.7%-2.3% of a zinc layer passivation agent, 0.4%-0.6% of an accelerator, 18%-22% of a penetrating agent, 30%-40% of a polymer filling agent, 1.8%-2.2% of a surfactant, 0.05%-0.15% of a defoaming agent, 0.8%-1.2% of hydrogen peroxide and the balance of water. The treatment solution is used for solving the problems that when the rust treatment solution is used for treatment of a metal with a relatively thick rust layer, an internal rust layer cannot realize complete reaction with the rust treatment solution, the internal rust layer cannot obtain the due chelation, the strength of a whole chelate membrane is affected, and the treatment effect of the rust treatment solution is seriously affected. The invention belongs to the field of metal rust protection.

Description

A kind of thick rust filled-type band rust treatment solution and preparation method thereof

Technical field

The present invention relates to a kind of band rust treatment solution, belong to metal rust preventing field.

Background technology

Iron and steel easily corrodes in atmospheric environment, according to statistics, the annual output of steel in the whole world about has 30% to be corroded, and for the steel anti-corrosive corroded, advancedly must cross manual polishing processing of rust removing and just can carry out anticorrosion and recycling, but manual polishing difficulty is high, cost is high, treatment effect is not satisfactory, and be subject to the factor impacts such as environment, if rust cleaning operation can be polished, significantly can lower painting cost, also greatly can simplify anticorrosion process simultaneously, thus reduce labor intensity and reduce rust dirt to the harm of human body.Based on above object, have developed the band rust treatment solution of water-based, can under the prerequisite without polishing rust cleaning, by active iron rust layer passivation, and chelating is converted into fine and close protective membrane, is attached on base material, thus protects base material, extend the work-ing life of base material.

But aqueous rusty treatment solution conversion capability common is at present limited, under conventional usage quantity condition, only top layer rusty scale chelating can be transformed, for the situation that rusty scale is thicker, inner rusty scale can not get due chelating, immutable densification, have impact on overall chelating film strength, simultaneously, common aqueous rusty treatment solution is in conversion chelating process, due to the chelating sealing process of top layer rusty scale, also have impact on the conversion of inner rusty scale, thus the chelating membrane causing rusty scale surface compact has been formed and has shielded outside band rust treatment solution, and inner rusty scale not yet starts to react with being with the treatment solution that becomes rusty, make conversion thorough not, thus make to be with the treatment effect of rust treatment solution very undesirable.

Summary of the invention

The object of the invention is to: a kind of thick rust filled-type band rust treatment solution and preparation method thereof is provided, to solve existing band rust treatment solution when processing the thicker metal of rusty scale, inner rusty scale cannot react with being with the treatment solution that become rusty completely, inner rusty scale can not get due chelating, affect overall chelating film strength, have a strong impact on the problem of band rust treatment solution treatment effect.

The solution of the present invention is as follows: a kind of thick rust filled-type band rust treatment solution, and by quality proportioning, described treatment solution comprises the Weibull of 0.4%-0.6%, the phytic acid of 0.4%-0.6%, the phosphoric acid of 4.5%-5.5%, the oxalic acid of 0.8%-1.2%, the zinc layers passivator of 1.7%-2.3%, the promotor of 0.4%-0.6%, the permeate agent of 18%-22%, the polymer weighting agent of 30%-40%, the tensio-active agent of 1.8%-2.2%, the defoamer of 0.05%-0.15% and the hydrogen peroxide of 0.8%-1.2%, surplus is water.

Preferably, zinc layers passivator be zirconium white and potassium permanganate in mass ratio 1:1 be composited.

Preferably, described promotor is cupric nitrate, Sodium orthomolybdate.

Preferably, described permeate agent be sodium diethylhexyl sulfosuccinate, part isopropyl and the trimethyl carbinol in mass ratio 1:10:5 mix.

Preferably, polymer weighting agent is that polyvinylpyrrolidone and oligomeric polyacrylamide mix.

Preferably, tensio-active agent is sodium laurylsulfonate.

Preferably, defoamer is polydimethylsiloxane.

The preparation method of above-mentioned band rust treatment solution, comprises the steps:

Step one: water intaking adds tensio-active agent, defoamer post-heating to 60 DEG C;

Step 2: the solution in step one adds Weibull and phytic acid, is stirred to dissolving, to be dissolved completely after add phosphoric acid, oxalic acid, zinc layers passivator and promotor and stir 30 minutes;

Step 3: water intaking adds permeate agent, and polymer weighting agent is stirred to dissolving, is slowly added by this solution in the solution in step 2 and go after dissolving, stirs 30 minutes, period drips hydrogen peroxide.

The present invention compared with prior art, mainly has the following advantages:

1, have employed Low acid system, reduce the shielding effect of chelated surface film, band rust treatment solution is more easily reacted with inner rusty scale;

2, have employed a large amount of permeate agents, add tensio-active agent simultaneously, band rust treatment solution can be made to arrive more rapidly bottom rusty scale, react with bottom rusty scale;

3, with the addition of hydrogen peroxide, control speed of reaction, prevent local reaction too fast and local following and react cause shielding effect, transform not exclusively, the problem such as chelating membrane is imperfect.

4, add a large amount of organic polymers, between the rusty scale being supported in chelating as weighting material, make the rusty scale of chelating membrane and floating pine finer and close, solid.

The present invention in use; without the need to carrying out meticulous polishing to metallic substrate surface; directly rapidly active iron rust layer can be transformed at metallic substrate surface spraying band rust treatment solution and be chelated to fine and close inertia protective layer; even if the thicker rapid conversion that also can realize rusty scale inside of rusty scale; guarantee that rusty scale each several part all transforms completely; substantially increase the changing effect of band rust treatment solution, improve the steadiness that thick rusty scale manages rear chelating membrane everywhere.
