Description
Technical field
The present invention relates to a kind of inorganic anti-corrosion paint, be specifically related to a kind of for substituting inorganic anti-corrosion paint of water base zinc-chromium coating and preparation method thereof and using method.
Background technology
Zinc-chromium coating (claiming again Dacromet/steel) is that water base zinc-chromium coating is coated on to metallic surface, the inorganic anti-corrosion coating forming through baking, and its antiseptic principle is the Cr utilizing in water base zinc-chromium coating
6+passivation zinc metal sheet and aluminium flake carry out redox reaction and form unbodied nGr under baking
2o
3mGrO
3composite salt, this composite salt and zinc metal sheet, the stacked metallic surface that covers of aluminium flake, form inorganic anti-corrosion coating.
The disclosed non-electrolytic metal corrosion preventing paint of Chinese patent literature CN1323860A is water base zinc-chromium coating, and it adopts chromic salt and molybdate as dual passivator.Due to Cr
6+be a kind of carcinogenic substance of heavily contaminated, very big to human body and environmental hazard, therefore, Chinese patent literature CN1539890A discloses a kind of improved non-electrolytic metal corrosion preventing paint, adopts tungstate substitute chromium hydrochlorate and molybdate to form dual passivator.
The deficiency of above-mentioned two kinds of inorganic anti-corrosion paints is: (1) adopts three component hybrid modes, and passivator needs preparation separately, thereby has increased process complexity; (2) antiseptic power is not good, and Chinese patent literature CN1323860A reaches salt fog resistance>=800h needs 240mg/dm
2coated weight, Chinese patent literature CN1539890A reaches salt fog resistance>=720h also needs 200mg/dm
2coated weight; (3) although Chinese patent literature CN1539890A has solved Cr
6+heavily contaminated problem, but be there is equally to certain harm in human body and environment as molybdenum and the tungsten of heavy metal, especially the molybdenum of ionic state is larger to harm.
Graphene is a kind of novel material of the individual layer sheet structure being made up of carbon atom, it be at present the thinnest be in the world the hardest nano material also, be the material of resistivity minimum in the world at present, therefore, it is most commonly used to electro-conductive material technical field,
At present, existing by Graphene the bibliographical information for high-molecular coating and zinc-riched epoxy coating, it is to utilize the synergy of the macromolecular compound generations such as Graphene and polyaniline, epoxy resin to improve antiseptic property.
But, not yet find at present Graphene for the bibliographical information on inorganic anti-corrosion paint, thereby especially utilize Graphene passivation zinc metal sheet and aluminium flake to play the bibliographical information of preservative activity.
Summary of the invention
One of object of the present invention is to address the above problem, and a kind of, inorganic anti-corrosion paint that antiseptic property higher less to human body and environmental hazard is provided.
Two of object of the present invention is to provide the preparation method of above-mentioned inorganic anti-corrosion paint.
Three of object of the present invention is to provide the using method of above-mentioned inorganic anti-corrosion paint.
The technical scheme that realizes one of the object of the invention is: a kind of inorganic anti-corrosion paint, and it is to be mixed according to the weight ratio of 1.1: 1～1.3: 1 by first component and second component; Described first component is mixed by the material of following weight per-cent: zinc metal sheet 21.6～27.8%, aluminium flake 3.5～4.6%, Graphene 1.5～4.0%, mixed type organic alcohol solvent 49.0～55.0%, water-soluble titanate coupling agent 8.0～12.0%, nonionic surface active agent 1.0～1.9% and dispersion agent 0.8～1.6%; Described second component is mixed by the mixed type organic alcohol solvent of 30wt～40wt% and the sticky water of 60wt～70wt%, and described sticky water is the deionized water that contains 0.5～1.0wt% thickening material.
Zinc metal sheet in described first component and the weight sum of aluminium flake are 12～16% of coating gross weight.
Described zinc metal sheet, aluminium flake are flakey, and sheet footpath is 5～40 μ m, and sheet is thick is 0.2～0.5 μ m.
Nonionic surface active agent in described first component is isomery undecyl alcohol Soxylat A 25-7, isomerous tridecanol polyoxyethylene ether or alkylphenol polyoxyethylene.
Dispersion agent in described first component is two amber ester sulfonate sodiums or Zinic stearas.
Thickening material in described second component is Natvosol or methylcellulose gum.
Described first component is identical with the mixed type organic alcohol solvent in second component, is two kinds in glycerol, polyoxyethylene glycol and ethanol or three kinds.
Two the technical scheme that realizes the object of the invention is: the preparation method of above-mentioned inorganic anti-corrosion paint, prepare respectively first component and second component, and then mix according to weight ratio; Being prepared as of described first component: first aluminium flake, Graphene, mixed type organic alcohol solvent, nonionic surface active agent and dispersion agent are joined to mix and blend 3～5h in agitator according to formula, then add zinc metal sheet, continue mix and blend 4～6h, finally add water-soluble titanate coupling agent, continue mix and blend 1h; Being prepared as of described second component: first thickening material is joined in deionized water according to formula, then add mixed type organic alcohol solvent to mix.
Three the technical scheme that realizes the object of the invention is: adopt two to be coated with two and to dry techniques inorganic anti-corrosion paint is coated in to metal material surface, coated weight is 100～150mg/dm
2, storing temperature is 280～300 ℃.Wherein, after coating for the first time, do not allowed holiday phenomenon to exist.
The positively effect that the present invention has: (1) inorganic anti-corrosion paint of the present invention adopts Graphene to replace passivator passivation zinc metal sheet and the aluminium flakes such as chromic salt, molybdate, tungstate, so neither contain heavy metals such as human body and the great Cr of environmental hazard, also containing the heavy metal such as Mo, W that human body and environment is had to the ionic state of certain influence, therefore, less to human body and environmental hazard, belong to green environmental friendly coatings.(2) inorganic anti-corrosion paint antiseptic property of the present invention is higher, only has 100～150mg/dm at coated weight
2situation under, can reach salt fog resistance>=720h, more than reaching as high as 1200h.(3) because Graphene of the present invention can be mixed together with zinc metal sheet and aluminium flake, thereby without preparing separately passivator solution, therefore greatly simplified preparation technology.
