Description

A kind of preparation method of surface modified graphite alkene aqueous polyurethane anticorrosive paint
Technical field
The present invention relates to anti-corrosion polyurethane coating more particularly to a kind of surface modified graphite alkene aqueous polyurethane anticorrosive paints Preparation method.
Background technique
There are also a large amount of organic solvent, organic solvent has inflammable, explosive, toxicity and endangers ring conventional urethane coating Border, so that conventional urethane coating high pollution high risk；Aqueous polyurethane coating has nontoxic, non-ignitable, free from environmental pollution, saving The advantages that energy.But aqueous polyurethane is not so good as solvent in many performances such as chemical-resistant, wearability, hardness, water resistance etc. Type polyurethane coating.
Graphene is a kind of two dimension (2D) stratified material of novel single-layer laminated structure being made of carbon atom, is by C original The hexangle type that son is formed with sp2 hybridized orbit is in the flat film of honeycomb lattice.There are 3 σ keys in each lattice, connection is very Closely, stable regular hexagon structure is formed, and is played during its conductive and heat-conductive perpendicular to the pi bond of crystal plane direction important Effect.
Unique structure makes graphene present huge potentiality in corrosion and wear field.Firstly, the sp2 that graphene is stable Hybrid structure can form Physical barriers between metal and active medium, prevent the progress of scattering and permeating；Secondly, graphene With good thermostabilization and chemical stability, no matter under the high temperature conditions, or in gas, the liquid for having corrosion or oxidisability Stabilization is able to maintain in body environment.In addition, graphene good conductive, heating conduction metal Service Environment is provided it is advantageous Condition.Still most thin so far material, the influence to substrate can be ignored graphene；It also has both simultaneously very high Intensity and good tribological property, can not only improve electric conductivity or fume resistance, moreover it is possible to further decrease coating layer thickness, enhance To the adhesive force of substrate, the wearability of coating is improved.The physics such as toughness, adhesive force, water resistance, the hardness of anti-corrosion material can be enhanced Chemical property.
But the conjugated structure of graphene causes it poor with the compatibility of water, organic solvent and polymer, works as additional amount When very little, the hardness and wearability of coating improve unobvious；When graphene additional amount is excessive, graphene is easy in coating It causes to agglomerate into hole, causes defect, this does not only improve performance, instead to hydrone, oxygen, chloride ion etc. Corrosion factor, which enters coating and penetrates into substrate, provides channel, accelerates the corrosion of substrate, thus it is in the application of paint field It is very restricted.
Summary of the invention
The present invention is directed to the problem of existing aqueous polyurethane coating anti-corrosion effect difference, provides a kind of surface modified graphite alkene water The preparation method of property anti-corrosion polyurethane coating.
The technical scheme to solve the above technical problems is that a kind of surface modified graphite alkene aqueous polyurethane anti-corrosion The preparation method of coating, which comprises the following steps:
1) it prepares graphite oxide powder: 10g ground graphite powder being immersed in 200ml concentrated nitric acid, impregnates 1- at 0 DEG C 2h is cooled to -15 DEG C, and 1ml concentrated phosphoric acid and 40g potassium ferrate is added, is centrifugated after -10 DEG C of -60 DEG C of reaction 0.5-24h, will It is 6-7 that filter cake, which is washed with deionized to washing lotion pH, is placed in a vacuum drying oven, 60 DEG C -70 DEG C dry 4-6h, and oxidation stone is made Ink powder end；
2) it prepares Multi-layer graphite powder: graphite oxide powder is being contained into NaBH4And CaCl2Solution in impregnate 8-10h after Filtering, after filter cake is washed with deionized in drying box 60 DEG C of dry 6h, obtain multilayer powdered graphite；
3) it prepares modified graphene powder: 8- will be impregnated in hydrazine hydrate under Multi-layer graphite powder room temperature obtained by step 2) 10h is filtered after immersion, filter cake be washed with deionized after in drying box 60 DEG C of dry 4h, be made contain carboxyl and hydroxyl The modified graphene powder of base；
4) it prepares modified graphene isocyanates composite solution: after powder obtained by 5g step 3) is fully ground, adding to 30ml is gone in water DMF, and 1h is stirred at 30 DEG C -80 DEG C, and excess of polyisocyanate is added, and catalyst is added and stirs 2h, uses every time 100ml acetone is washed, the side's of removing dark solution, takes lower layer's dark solution to get modified graphene isocyanates composite solution；
5) it prepares the isocyano group tripolymer containing modified graphene: acetone is added in hydrophilically modified polyisocyanates tripolymer In, composite solution obtained by step 4) is added at 20 DEG C -50 DEG C, after mixing evenly, vacuum distillation removes acetone, is made containing modified stone The isocyano group tripolymer of black alkene；
6) two-component anticorrosive paint is prepared: by the isocyano group tripolymer and polyalcohol point obtained by step 5) containing modified graphene Anticorrosive paint is made in granular media barrier packaging.
Further, polyisocyanates described in step 4) is one of MDI, TDI, HMDI or IPDI or a variety of.
Further, in the isocyano group tripolymer described in step 6) containing modified graphene-NCO group and the polyalcohol In the ratio between the amount of substance of hydroxyl-OH be (0.8-1.9): 1.
Surface modified graphite alkene aqueous polyurethane anticorrosive paint that the above method is prepared is also claimed in sea in the application The application in the standby surface anticorrosion field of Western-style clothes.
The beneficial effects of the present invention are: graphite stable in surface modified graphite alkene aqueous polyurethane coating of the invention Sp2 hybrid structure is attached to substrate surface, and Physical barriers can be formed between substrate and active medium, prevents scattering and permeating Progress, prevent the infiltration of the corrosion sex factor such as hydrone, oxygen, chloride ion, make coating that there is good weatherability, durable Property, gloss retention and colour retention, are not pulverized easily, yellowing, good decorative property.Graphene surface is after isocyanate-modified without acutely stirring Mixing uniform and stable can be dissolved in aqueous polyurethane coating, solve the problems, such as that graphene dissolubility is poor, enhance coating The performances such as anticorrosion antiwear.The modified multi-layer graphene in surface contained by surface modified graphite alkene aqueous polyurethane coating of the invention Intensity is high, reduces coating layer thickness, increases coating to the adhesive force of substrate, improve wearability, water-fast and resistance toization of coating Learn moral character energy.Surface modified graphite alkene aqueous polyurethane anticorrosive paint VOC free, heavy metal free obtained by of the invention meet country to sea The health of foreign heavy antisepsis, environmental protection, safety requirements are widely used in the production corrosion-resistant field such as ship, drilling platform, artificial reef, apply The coating method that work mode can select according to demand painting, spraying etc. different.
