Description
Technical field
The present invention relates to a kind of galvanizing environmental protection passivating solution and preparation method thereof, belongs to field of metal surface treatment technology.
Background technology
Hot dipping coating technology is the extensive and simple to operation ferrous materials anticorrosion technique of popularization.Hot dipping is also named in galvanizing
Zinc and galvanizing by dipping, are the steel part after rust cleaning to be immersed in the zinc liquid of 500 DEG C or so fusings, make steel beam column surface attachment zinc layers,
It is a kind of effective anti-corrosion of metal mode so as to play corrosion-resistant purpose, is mainly used on the metal structure facility of every profession and trade.Heat
Zinc-plated developed by more ancient hot-dipping method, and hot dip Zn Cr coating is to send out with the at full speed of cold-strip steel in recent decades
Exhibition just obtains extensive development.Hot dipping zinc-plating workpiece it is water cooled but after, need long period accumulating, in storage and transport process easily
Generation corrosion phenomenon, Surface Creation " white to embroider ", in order to prevent white rust, need to be passivated process, to protect workpiece to exist on its surface
Will not be corroded in transportation.
Now industrial the most frequently used passivation of metal surfaces handling process is chromating technique.Main cause is chromic acid
Salt passivation technology is simple, and cost is relatively low, and etch resistant properties are excellent, and chromate passivation film has stronger self-healing ability, chromate
Chromium in passivating solution is mainly in the form of Cr VI and trivalent chromium, but Cr VI toxicity is larger, and is carcinogen,
Serious environment pollution, injures human body；Though trivalent chromium toxicity is little, in use, trivalent chromium is oxidizable for Cr VI, or
Pollution can not be solved the problems, such as.So research it is a kind of can with replace chromate environmentally friendly passivation mode have far-reaching significance it is wide
Application prospect.
Research both at home and abroad to chromium-free deactivation at present mainly has two big class：One is inorganic matter passivation mode, such as silicate, molybdenum
Hydrochlorate, titanium salt, tungstates, rare earth metal salt etc., two is organic passivation mode, and such as organic silanes, phytic acid passivation, tannic acid are blunt
Change etc..But the passivation effect of both modes is all undesirable, some film layers are loose, and compactness is inadequate, and corrosion resisting property is poor, has
Film formation time it is longer, cumbersome, the mode having in addition is relatively costly, no matter inorganic passivation or organic passivation, all can not
Reach the level of commercial Application.
The content of the invention
The present invention adds acrylic resin in passivating solution, improves the compactness of passivating film, improves passivation film outward appearance,
The corrosion resisting property of galvanized part can be improved.
It is an object of the invention to provide a kind of galvanizing environmental protection passivating solution, including following components：Acrylic resin soln 80-
150mL/L, sodium tungstate 10-30g/L, sodium nitrate 15-25g/L, thiocarbamide 5-20g/L, sodium fluoride 8-22g/L, sodium citrate 5-
20g/L, H2O22-5mL/L, remaining is water.
The acrylic resin soln is acrylic resin, the mixture of the ammoniacal liquor of isopropanol, mass fraction 26% composition,
Wherein the mass percent of acrylic resin be 30-55%, isopropanol mass percent be 25-50%, the ammonia of mass fraction 26%
The mass percent of water is 8-20%.
The sodium tungstate, sodium nitrate, thiocarbamide, sodium fluoride, sodium citrate, H2O2It is commercially available analysis pure chemistry reagent, water
For deionized water.
Further object is that providing the preparation method of the galvanizing environmental protection passivating solution, concrete steps are such as
Under：Sodium tungstate, sodium nitrate, thiocarbamide, sodium fluoride, sodium citrate are dissolved in water in proportion, be heated to during dissolving 50 DEG C-
60 DEG C and stir, mix several solns after being completely dissolved, add H2O2Stir, stand 15min；Proportionally prepare
Acrylic resin soln, acrylic resin soln is proportionally added into mixed solution, is slowly added to using pipette, side edged
Stirring, until being completely dissolved, then adding water, it is volume required to be settled to, that is, obtain galvanizing environmental protection passivating solution.
When using, it is put into after heat zinc coating plate is cleaned in passivating solution and constantly rocks, room temperature passivation 40-60s completes passivation
Take out kept dry.
Beneficial effects of the present invention：Galvanizing environmental protection passivating solution of the present invention, passivation technology is simple, low cost, and is preparing
During do not add harmful substance, toxic gas is not produced in preparation process, pollution is not resulted in environment, human body will not be made
Into injury, and Several Thiourea Derivatives on Zinc Plate Surface generate passivating film densification it is smooth, smooth, passivating film corrosion resistance is good, to matrix have compared with
Good protective effect.
Specific embodiment
With reference to specific embodiment, the present invention will be further described, but protection scope of the present invention and is limited to institute
State content.
