Description
Technical field
The invention belongs to technical field of coatings, specifically a kind of super-hydrophobic composite coating and preparation method thereof.
Background technology
In recent years, bionic biology has caused increasing people to pay close attention to, and people's back to nature, is found in nature
New scientific research break-through point.The super-hydrophobicity and automatically cleaning effect on plant leaf surface cause the great interest of people.
The microstructure that Barthlott and Neinhuis passes through observation of plant leaf surface, it is believed that this self-cleaning feature is by coarse
The presence of the mastoid process of micrometer structure and surface wax is jointly caused on surface.Chinese Academy of Sciences researcher Jiang Lei is in this research
On the basis of it has also been found that " nanostructured, this nanostructured and micrometer structure in the mastoid process of lotus leaf surface micrometer structure be present
The dual microtexture that is combined of mastoid process be the basic reason for causing surface soiling self-cleaning.Lotus leaf and Rice Leaf it is this super-hydrophobic
The principle of characteristic, the wetability that artificial super hydrophobic surface and design interface are built for people provide guidance.
People do not get wet this on this lotus leaf, and the phenomenon that water droplet oneself can tumble is referred to as super-hydrophobic phenomenon, will have
The surface for having this property is referred to as super hydrophobic surface, wherein the contact angle of super hydrophobic surface generally more than 150 °, roll angle it is small
In 10 °.The preparation methods of current many super hydrophobic surfaces it has been reported that the method for the collosol and gel such as Rao, using methyl-monosilane as
Presoma, in methanol solution, ammoniacal liquor is catalyst, and the CA of obtained coarse silicon Aerosol Surface is up to 170 °；Lau etc. exists
With one layer of conformal poly tetrafluoroethylene of chemical vapor deposition on the surface of carbon nano pipe array film, obtained material
Surface has good hydrophobicity；Han Yanchun etc. to PTFE rubber strips by simply being stretched, with the increase of extensibility,
The increase of the distance between fibrous PTFE crystal of rubber is formed, causes the roughness on surface to increase, surface C A is consequently increased.
In 190% extensibility, CA is up to 165 °；Erbil etc. using isotactic polypropylene as film forming matter, by select suitable solvent,
Precipitating reagent and film-forming temperature regulate and control the crystalline rate of polymer in solution film forming process, have obtained the polymerization with loose structure
Thing surface, the CA with water is up to 160 °；River thunder etc. squeezes into polyacrylonitrile original solution in solidification liquid by porous alumina formwork
Solidification, the needle-like polyacrylonitrile nanofiber array of preparation and the CA of water are up to 173 °；(7) river thunder etc. is obtained slightly with electrochemical deposition
Rough zinc oxide surface, CA are 128 °, and CA brings up to 152 ° after silicon fluoride is handled；(8) Liu Weimin etc. uses sodium hydroxide solution
The surface for corroding aluminum or aluminum alloy obtains rough surface, respectively after fluothane or vinyl organosilicon hydrophobic modification, obtains gold
Belong to the super hydrophobic surface of substrate.
The super-hydrophobic characteristic of the surface of solids is together decided on by the hydrophobicity and roughness of material, low surface free energy and suitable
Suitable roughness is two indispensable factors.At present, solid material surface coating super hydrophobic coating is typically employed in be formed
The mode of super-hydrophobic coat improves the hydrophobicity of material surface；Super hydrophobic coating, which forms super-hydrophobic coat, typically has low-surface-energy
Hydrophobic surface, suitable surface roughness and low slide angle.Report at present on super-hydrophobic coat is a lot, but super thin

Poor (such as hardness, adhesive force, wearability).Most super hydrophobic surface is easy for losing super thin under the destruction of very little external force
Water-based energy, some is even gently with hand or brush with regard to that can wipe.Up to the present, both at home and abroad on good mechanical properties
Super-hydrophobic coat or coating report it is seldom, and its hardness is all without also can only be in sand paper more than 3H, wearability
Several centimetres or tens centimetres are ground above.Recently, Lu Yao et al. exist《Science》2015,347:Him is reported on 1132-1135
Super hydrophobic material is bonded to different base materials with adhesive, obtained the super hydrophobic surface of super abrasive：It is coated on slide,
Under 100g counterweight pressure, ground on the sand paper of 240 mesh, every time 10 centimetres of mill, still there is superhydrophobic characteristic after grinding 40 times.But
It is that the super-hydrophobic of this double-deck system can make troubles in practice of construction application.Therefore exploitation is good with high rigidity, wearability
Super-hydrophobic coat it is very necessary.
