Description
Technical field:
The invention belongs to Metal surface anti-corrosion processing technology field, be specifically related to relate to a kind of steel surface process normal temperature rust cleaning blackening agent for surface and preparation method thereof.
Background technology:
At present, needing to carry out its technique of blackening process at component surface for preventing the rust corrosion of steel-iron components generally adopts oil removing → water rinse → rust cleaning → water rinse → activation → water rinse → blackout → water rinse → leaching dewatering rust preventive oil to close, most room temperature blacking liquids that prior art uses are all containing selenide, selenide price is not only expensive but also have severe toxicity, and life-time service certainly will cause environmental pollution.Chinese patent CN201310199938.6 discloses a kind of self-healing Environmental Blackening Agent At Room Temperature For Steel, this blackening agent for surface adopts the preparations such as cupric nitrate, Ammonium Molybdate Tetrahydrate, Sulfothiorine, SODIUM PHOSPHATE, MONOBASIC, oxalic acid, single nickel salt, dimethyl formamide, lanthanum trioxide, potassium aluminium sulfate, sodium-chlor, citric acid and tensio-active agent, this blackening agent for surface blackout ability is comparatively strong, simple without selenium environmental protection, technique, the Chemical Colouring of Steel at Room Temperature rete of blackout gained has good solidity to corrosion and self-healing, but have that solution precipitation is many, blackout layer and the shortcoming such as matrix metal bonding force is poor.Chinese patent CN201110030425.3 discloses a kind of zinc-chromium membrane blackening agent, and raw material is in mass ratio: trifluorochloroethylene: 78-90%; Blackening agent for surface (carbon black): 2-5%; Vinyl chlorosilane: 0.1-0.5%; Primary zinc phosphate and ferric sulfate: 3-5%; Sodium laurylsulfonate: 0.1-1%; Full methyl-etherified aminoresin: 0.1-0.6% mixes, blackening layer of this invention process is the rete that one deck contains fluoride resin, and rete outward appearance is evenly shiny black, avoids traditional enamelling process and to show money or valuables one carries unintentionally phenomenon, but blackening agent for surface poor stability prepared by this technique, resin and carbon black dispersion are stable not.Both invention disclosed patents all need acid pickling and rust removing above, blackening agent for surface blackening agent for surface of the present invention is simple without selenium environmental protection, preparation technology, directly in steel surface rust cleaning blackout, with techniques such as alternative acid pickling and rust removings, and the feature that blackout speed is fast and antiseptic property is excellent that eliminates rust can be had.
Summary of the invention:
The present invention is directed to the above-mentioned technical problem that rust cleaning blackening agent for surface exists, a kind of normal temperature rust cleaning blackening agent for surface and preparation method are provided, this blackening agent for surface can directly in steel surface rust cleaning blackout, in order to avoid remove the techniques such as acid pickling and rust removing and selenium-containing compound, and there is the rust cleaning blackout speed advantage that blackout is even, antiseptic property is excellent soon.
Composition and the mass percent thereof of a kind of normal temperature rust cleaning blackening agent for surface provided by the present invention are:
Described composite emulsion is modified acroleic acid antirust emulsion, ACURE805 emulsion and epoxy emulsion are composited; Described rust removing solution is that oxalic acid, phosphoric acid, zinc phosphate and deionized water are composited; Described hair blackening liquid is that pyrogallol, Whitfield's ointment, Sunmorl N 60S and deionized water are composited; Described Polyaniline emulsion is with Witco 1298 Soft Acid and Weibull Tree-tea interplantation and employing micro emulsion legal system is standby.
Preparation method's concrete steps of a kind of normal temperature rust cleaning blackening agent for surface provided by the present invention are as follows:
(1) rust removing solution is prepared:
Get 5 parts of oxalic acids to be added in 70 parts of deionizations water and to stir and make it dissolve completely, then the phosphoric acid slowly adding 20 parts of 85wt% stirs, finally add 5 parts of zinc phosphates continue to stir 0.5h under normal temperature condition after obtained described rust removing solution.
(2) hair blackening liquid is prepared:
In 78 parts of deionized waters, first add 10 parts of pyrogallols stir and make it dissolve completely, then add 10 parts of Whitfield's ointments and stir, finally add 2 parts of Sunmorl N 60Ss, obtained described hair blackening liquid after continuing to stir 0.5h under normal temperature condition.
(3) composite emulsion is prepared:
Get 10 parts of epoxy emulsions to be added in 60 parts of modification acrylate antirust emulsions and to stir, then add 30 parts of described ACURE805 emulsions, obtained described composite emulsion after stirring at normal temperature 20min makes it be uniformly dispersed completely.
(4) target product normal temperature rust cleaning blackening agent for surface is prepared:
In the deionized water of specified amount, add described nano imvite, glycerine and Polyaniline emulsion respectively stir, rust removing solution prepared by step (1) is first added when constantly stirring, hair blackening liquid prepared by step (2) is slowly added again after stirring, continue dispersed with stirring 20min, slowly add composite emulsion prepared by step (3) again, finally slowly add lauryl alcohol ester, continue to stir 0.5h at normal temperature condition and obtain described normal temperature rust cleaning blackening agent for surface.
Described modified acroleic acid antirust emulsion is the WH3108 type antirust emulsion that Ningjin, Shandong five lakes Chemical Co., Ltd. produces; Described ACURE805 emulsion is a kind of aliphatics Anionic Polyurethane Dispersion containing polycarbonate of source, Shanghai standing grain Chemical Manufacture; Described nano imvite is the SMP-X40 model nano imvite that Zhejiang Fenghong New Material Co., Ltd. produces.
It is composite cleverly that the present invention adopts rust removing solution, hair blackening liquid and composite emulsion to carry out, directly can eliminate rust on the surface of the steel and iron member got rusty, turn black and film forming thus by rust cleaning, turn black in one, there is the feature of Simplified flowsheet, decreasing pollution; Substitute toxic selenium-containing compound owing to adopting the environment-friendly type hair blackening liquid of pyrogallol, Whitfield's ointment, Sunmorl N 60S composition and create beyond thought blackout preservative effect at compound system, because filming emulsion and Polyaniline emulsion can make film forming after blackout fine and close and due to the fabulous corrosion inhibition of polyaniline, add film coalescence aid lauryl alcohol ester and nano imvite, thus significantly improve blackening agent for surface antiseptic property.In addition, owing to adopting the compound of modified acroleic acid, water-base epoxy and the aliphatics Anionic Polyurethane Dispersion containing polycarbonate, play performance outstanding separately, because urethane, epoxy resin have low, the excellent water tolerance of film-forming temperature and sticking power, acrylic resin, urethane have good weathering resistance, gloss retention, make film forming matter emulsion " maximize favourable factors and minimize unfavourable ones " separately therefore can to produce beyond thought positively effect.
The present invention have rust cleaning and blackout speed fast and evenly, room temperature blackening, easy construction, the rust cleaning that directly can be used in steel beam column surface, blackout, rotproofing and containing features such as toxic substances, therefore product energy-conserving and environment-protective of the present invention.
