Description
Technical field
The invention belongs to wind energy conversion system manufacturing technologies, relate generally to a kind of in the pneumatic equipment bladess coating anti-icing painting of molybdenum sulfide nanometer
The technical method of layer.
Background technique
In recent years, due to a large amount of energy consumptions of human production life, natural energy source exhaustion has been asking for various countries' extensive concern
Topic.In order to solve energy crisis, renewable resource is made full use of, wind-power electricity generation project has received widespread attention.It is sent out in wind-force
In electric system, aluminium alloy wind turbine blade is the critical elements for obtaining wind energy.However, being exposed under cold wet weather
Often there is icing phenomenon in wind turbine blade.If the ice sheet formed on wind turbine blade is not eliminated in time,
The problem of wind turbine power generation is obstructed may occur.In order to guarantee the maximum reliability of pneumatic equipment bladess, reduce caused by freezing
Economic loss only reduces or eliminates two kinds of main methods of pneumatic equipment bladess accumulated ice, comprising: (1) active deicing method, example at present
Such as mechanical technique or heating, ultrasonic wave；(2) passive deicing method uses hydrophobic coating or plated film on pneumatic equipment bladess surface
Method.Wherein, it is widely used that electric heating active clearing ice technology, but its cost of electricity-generating improves；The passive deicing such as hydrophobic coating
Technology is cheap and environmentally friendly, does not need to complete deicing using extra power or prevents accumulated ice, but due to the deicing properties to coating
It is more demanding.Until up to now, still without the success of ideal pneumatic equipment bladess ice-phobic coating technical research.
Summary of the invention
The purpose of the present invention is to the above-mentioned problems of the prior art, study a kind of in the painting of pneumatic equipment bladess surface
Molybdenum sulfide nanometer ice-phobic coating technical method is covered, reaches that the anti-freeze effect of pneumatic equipment bladess is good, manufacture and use are low in cost, simple
Change anti-frozen structure, low cost utilizes the purpose of renewable energy.
The object of the present invention is achieved like this: a kind of pneumatic equipment bladess coating molybdenum sulfide nanometer ice-phobic coating technical side
Method, the method are: nanoscale vulcanization molybdenum powder being carried out to 0.5-1 hour ball milling, until volume-diminished is original volume
After half, by vulcanization molybdenum powder, the concentration after ball milling be 5% adhesive naphthols, purity be that analytically pure solvent is anhydrous
Ethyl alcohol is mixed with the mass ratio of pure material 8:1:5, the sticky slurries of black is obtained after being stirred by ultrasonic uniformly, by the sticky slurries of black
After being coated uniformly on pneumatic equipment bladess case surface with 8-12 μ m thicks, pneumatic equipment bladess are put into drying box in 50 DEG C of items
Part is 24 hours dry, i.e. coating of the completion black Mo sulfide nano coating on pneumatic equipment bladess surface.
The present invention is on the basis of giving full play to and utilizing material molybdenum sulfide hydrophobic property, processing and processing through science
Afterwards, it is coated onto pneumatic equipment bladess case surface, forms anti-icing coatings, pneumatic equipment bladess case surface is made to generate height
Hydrophobic property, avoid, eliminate and solve the generation of pneumatic equipment bladess icing phenomenon in cold wet environment, have technology
Method is novel, rationally, simple, coating is from heavy and light, the anti-freeze effect of pneumatic equipment bladess and good seal performance, long service life, suitable
Answer the feature that environment capacity is strong.
Detailed description of the invention
Fig. 1 is the static contact angle schematic diagram of uncoated any coating Shi Yushui in pneumatic equipment bladess case surface；
Fig. 2 is to illustrate after coating molybdenum sulfide nano coating in pneumatic equipment bladess case surface with the static contact angle of water
Figure.
Specific embodiment
Embodiment of the present invention is described in detail with reference to the accompanying drawing.A kind of pneumatic equipment bladess coating molybdenum sulfide nanometer
Ice-phobic coating technical method, the method are: nanoscale vulcanization molybdenum powder being carried out to 0.5-1 hour ball milling, until volume contracts
After the small half for original volume, by vulcanization molybdenum powder, the concentration after ball milling be 5% adhesive naphthols, purity be point
It analyses pure solvent absolute ethyl alcohol to mix with the mass ratio of pure material 8:1:5, obtains the sticky slurries of black after being stirred by ultrasonic uniformly,
After the sticky slurries of black are coated uniformly on pneumatic equipment bladess case surface with 8-12 μ m thicks, pneumatic equipment bladess are put into dry
It is 24 hours dry in 50 DEG C of conditions in dry case, i.e. coating of the completion black Mo sulfide nano coating on pneumatic equipment bladess surface.Examination
Test detection:
Referring to Fig. 1.When uncoated any coating on wind energy conversion system aluminum alloy material blade shell surface, outside pneumatic equipment bladess
The static contact angle of shell surface and water is 37.1 °, belongs to hydrophily, pneumatic equipment bladess easily freeze.
Referring to fig. 2.It is quiet with water after coating molybdenum sulfide nano coating on wind energy conversion system aluminum alloy material blade shell surface
State contact angle is greater than 123.5 °, and coating has very hydrophobic characteristic, and pneumatic equipment bladess are not-easy-to-freeze.
Wind-tunnel dynamic ice experiments have shown that, the hydrophily wind-force of uncoated any coating in pneumatic equipment bladess case surface
Machine leaf weight linearly increases, it was demonstrated that the anti-freeze effect of the blade is poor；Molybdenum sulfide is coated in pneumatic equipment bladess case surface
The high hydrophobicity pneumatic equipment bladess weight growth of nano coating is close to zero, and also proves that the coating has the good anti-caking of height
Ice effect.
