Material and preparation method thereof.
Background technology
Flue gas desulfurization apparatus system has been the environmental protection dress that power plants and other stoves cellar for storing things, sintering machine requirement must have
Put, in sulfur removal technology wet desulfurization of flue gas by limestone-gypsum method be at present in the world technology it is most ripe, be adapted to China's national situation and
The most high-efficiency desulfurization technique of domestic application（Refer to large desulfurization device）, but find in actual applications, flue gas desulfurization contains powder
Dirt, SO2, HF, HCl, NOx, vapor, H2SO3、H2SO4Deng complicated component, soda acid alternating colds and heat succeed each other, alternation of wetting and drying, rotten
Erosion is with wearing and tearing and depositing, and desulphurization plant subjects diversified physics, chemistry, temperature and mechanical load, particularly liquid phase ingredient
SO3 2-、SO4 2-、F-、Cl-The complicated desulfurization corrosive environment such as strong corrosion to equipment and materials.
The coating of existing flue gas desulfurization device is typically with bisphenol A type epoxy resin, novolac epoxy resin, phenolic aldehyde bisphenol-A
Type modified epoxy class, bisphenol-A unsaturated polyester (UP) class, vinyl acrylate class, methacrylate vinyl matrix class, epoxy novolac
The glass flake plasticine that a few resinoid systems such as vinyl ester are done.But there is following lack when in use in glass flake class coating
Fall into：1st, after constructing, due to being stopped by glass flake layer, solvent is difficult to volatilize, and easily produces the various films related to solvent
Defect, such as：Foaming, hollowing, come off；Solvent-borne type flake paint is only suitable for thin coatings.2nd, glass flake class coating is due to adding
Enter a large amount of glass flakes（Usually more than 30%）And other wear resistant fillers, cause adhesive force of the coating on base material poor, easily
Come off, especially during long-term use, easily large area is peeled off.
In order to solve the above-mentioned technical problem, following technology is proposed in the prior art：
China Patent No. notification number disclosed a kind of " resistance to height for the prior art of " CN105694658A " on June 22nd, 2016
Warm graphene/vinylite anticorrosive paint and preparation method thereof ", its technical scheme is：By graphene content 10wt% stone
Black alkene/vinylite masterbatch is added in vinylite, adds diluent and auxiliary agent stirring is allowed to be uniformly dispersed to form A
Component；B component is curing agent, and component C is curing accelerator.By weight percentage, component A accounts for 52.8 ~ 92.7%, and B component is accounted for
3.3 ~ 33.0%, component C accounts for 3.1 ~ 24.7%；In component A, the content range of graphene is 0.064 ~ 4.7wt%.By three components
It is mixed evenly and can be made into graphene/vinylite composite coating, applies can be made into tool after drying according to a conventional method
There is the corrosion protective coating of high temperature resistant acidic flue gas corrosion.The graphene composite coating that the patent is prepared can take into account resistance to height
Warm, acidproof, resistance to HF corrosion, coating combination property is better than Conventional glass scale composite coating.But in actual use, this is special
Profit still has following defect：First, the coating that the patent is obtained is liquid, in practice of construction application, there is construction technology
Problem, because inner wall of stack is closed state, no matter spraying, is brushed, roller coat can all produce coating cloud or solvent volatilization pollution, pole
Workmen's poisoning problem is easily caused, construction is difficult；In addition, liquid coating can not form sufficiently thick film, in fire
Desulfurizing tower of electric power plant construction field, coating thickness is usually 0.5-4mm, and its product can not be realized in application technology, it is impossible to be reached
Construction requirement.2nd, graphene is carried out decentralized processing by the patented product in advance in the preparation, is fabricated to graphene masterbatch, then
It is added to again in coating system, there is the complicated defect of manufacturing process.3rd, the patent coating is three components, and workmen exists
It is cumbersome during addition, simultaneously as curing accelerator addition is few, if metering is inaccurate, it may result in film performance
There is relatively large deviation.
