Description
Technical field
The invention belongs to cleaning metal surface processing technology field, be specifically related to a kind of multifunctional efficient pickling acid suppression inhibiter of environment-friendly type.
Background technology
Acid pickling and rust removing is the technique that steel product surface cleaning and processing pre-treatment generally adopt, and is widely used in the industries such as metallic substance, metal material surface process, machinery, metallurgy, chemical industry.Hydrochloric acid is most widely used pickling agent, and chlorohydric acid pickling has the advantages such as pickling capacity is maximum, speed is fast.And the industrial difference according to iron and steel component and shaping industry, in order to reach the effect that better eliminates rust, adds a certain amount of nitric acid or processing of rust removing is carried out in hydrofluoric acid mixing usually in hydrochloric acid.But owing to there is chemical reaction between metal and pickle solution in the volatility of these acid and acid cleaning process, the gases such as H2, NOX of producing can carry acid and form acid mist in quick effusion process, Pickling-shop acid mist is caused to fill the air, cause serious environmental pollution, be detrimental to health, and very easily cause the strong corrosion of workshop appliance, facility.In addition, in pickling steel substrate easily with acid-respons releasing hydrogen gas, make steel part surface generation hydrogen embrittlement, and easily cause base metal surface excessive erosion, affect workpiece surface quality and intensity.
In order to reduce acid mist volatilization, cleaning shop environment, improving the surface quality of pickling steel part simultaneously, preventing the generation of hydrogen embrittlement, generally adopt the acid cleaning process adding antifog and corrosion inhibitor for pickling in pickle solution at present.Form the micro-nano rete possessing some strength by tensio-active agent on pickle solution surface on the one hand, stop the volatilization effusion of acid, add inhibiter on the other hand and suppress steel substrate and acid-respons, prevent hydrogen embrittlement from playing the effect reducing acid mist simultaneously.But press down mist corrosion mitigating effect from current, press down the function singleness of mist inhibiter, large to the pickling quality difference of unlike material steel part, undesirable to the pickling effect in nitration mixture pickle solution, adaptive surface is narrow.For this reason, develop the multi-functional efficient mist inhibiter that presses down and there is important economic worth.
Summary of the invention
Object of the present invention is mainly for current antifog and corrosion inhibitor for pickling function singleness, and large to unlike material pickling iron and steel difference in quality, the present situation that nitration mixture result of use is undesirable, provides efficient antifog and corrosion inhibitor for pickling of environment protection type multifunctional and preparation method thereof.
For achieving the above object, the present invention by the following technical solutions:
The efficient antifog and corrosion inhibitor for pickling of a kind of environment protection type multifunctional, primarily of tensio-active agent, inhibiter, permeate agent, the multiple composition such as acid pickling promotor is composite to be formed, and the synergy between each component makes product in pickling, reach best to press down mist corrosion mitigating effect.
The composition number of described each component is: tensio-active agent 2 ~ 6, inhibiter 8 ~ 15, permeate agent 0.5 ~ 1, promotor 2 ~ 4, water 74 ~ 87.5.
Described tensio-active agent is made up of the one in peregal, Sodium dodecylbenzene sulfonate, SDS, alkylphenol polyoxyethylene or two kinds.
Described inhibiter is made up of two kinds or three kinds in urotropine, citric acid, Trisodium Citrate, ethylenediamine tetraacetic acid (EDTA), Tripotassium Citrate sodium, Seignette salt, extra large bath acid sodium, potassiumiodide, benzotriazole.
Described promotor is the one in Sulfothiorine, sodium-chlor, S-WAT.
Described permeate agent is the one in fatty alcohol-polyoxyethylene ether (benzene permeate agent), methyl alcohol, ethanol, propyl alcohol.
Described antifog and corrosion inhibitor for pickling, its preparation method is as follows: be successively added to the water by the tensio-active agent of described weight part and stir until dissolve completely, then add inhibiter successively, promote Liu, permeate agent, limit edged stirs, until dissolve completely, last make up water, to specified amount, namely obtains efficient antifog and corrosion inhibitor for pickling of the present invention.
The using method of described antifog and corrosion inhibitor for pickling is as follows: add antifog and corrosion inhibitor for pickling of the present invention by the amount of 1 ~ 2% in pickle solution, stirs and can use.
Beneficial effect of the present invention is:
(1) speed of derusting is fast, and permeate agent and adding of promotor significantly improve rust cleaning speed, when addition is 2%, generally can remove clean completely at 5-30 minute.(2) press down mist good: after measured, this product in the pickle solution of 25% concentration of hydrochloric acid its press down mist rate up to more than 90%, for hydrofluoric acid, nitric acid etc. also have extraordinary press down mist.(3) rust inhibition is good: after measured, and 45
#steel its corrosion inhibition rate after the pickle solution of 25% concentration of hydrochloric acid adds this product 1.5% reaches more than 99.8%, and for steel part prepared by unlike material and different forming method, all there is extraordinary pickling rust inhibition, pickling part surface whiteness is good, without excessive erosion, and zero defect.
