Description
Technical field
The present invention relates to a kind of super hydrophobic material and preparation method thereof.
Background technology
Airframe icing has high risks to Flight Safety.Mechanical deicing, electro-thermal deicing, the hot deicing of gas and change
It is conventional aircraft surfaces clearing ice technology to learn the technologies such as deicing liquid deicing.Though these technologies solve aircraft table to a certain extent
Face ice formation issues, but all with deicing, ice-melt as thinking, after ice after aircraft surfaces are formed, then it is removed from aircraft surfaces, no
Airframe icing can be solved from root, and there is high energy consumption, the problems such as environmental pollution is big.
Subcooled water clashes into aircraft surfaces, and it is the key for causing airframe icing that can not depart from from aircraft surfaces for a long time.
Airframe icing is fundamentally solved the problems, such as, the time of contact of subcooled water and aircraft surfaces need to be reduced, make it before icing
Come off from aircraft surfaces.By lotus leaf effects, researchers propose super hydrophobic surface concept.Super hydrophobic surface is class tool
There is the surface of specific physical chemical property, its surface contact angle is more than 150 °, and roll angle is less than 10 °, and small sample perturbations can make quiet
Rapid the tumbling of drop only on surface does not remain, and this just provides method to solve airframe icing from source.Ding Guifu
Etc. a kind of nano superhydrophobic surface preparation method (A of CN 101704410) for airplane antifreezing and deicing is proposed, by the method
The aircraft surfaces of preparation reduce the viscous force that water droplet slips over fuselage surface, reduce the quantity that the globule condenses in fuselage surface,
Effectively reduce the icing degree of aircraft surfaces.
However, numerous studies show super hydrophobic surface poor durability, and after multiple icing deicing circulation, surface micro-nano structure
Destroyed, hydrophobic ability declines.(see S.Farhadi, M.Farzaneh, S.A.Kulinich. " Anti-icing
performance of superhydrophobic surface",Applied Surface Science 257(2011)
6264-6269.S.A.Kulinich,S.Farhadi,K.Nose.X.W.Du"Superhydrophobic surface:are
they really ice-repellent"Langmuir Letter 2011,27(1),25-29).More there is research to point out, it is super thin
Water surface is long-term under the irradiation of ultraviolet light, and progressively Yet-have loses hydrophobic ability.The research of Xiu is pointed out, in the purple by hundreds of hours
After outer light aging test, the super hydrophobic surface of the hydrophobic coatings such as polydimethylsiloxane, polybutene, surface contact angle difference are coated with
From 153 °, 162 ° are reduced to 80 °, and 70 °, its hydrophobic ability is still lost on surface completely.(Xiu Yonghao,Fabrication of
Surface Micro-and Nanostructures for superhydrophobic surfaces in electric
and electronic applications,PhD Dissertation,Georgia Institute of Technology,
2008) aircraft is irradiated by ultraviolet for a long time in high-altitude flight, can not such as be solved the above problems, and will be unable to realize super-hydrophobic table
Application of the face on seating plane.United States Patent (USP) US2015/0368496A1 proposes a kind of uvioresistant super-hydrophobic coat and matches somebody with somebody

However, the formula that patent US2015/0368496A1 is proposed only can guarantee that for a long time under the irradiation of ultraviolet light, surface contact angle
Not less than 140 °, rather than 150 ° of (notes：When surface contact angle is more than 90 °, during less than 150 °, the surface is known as hydrophobic table
Face, rather than super hydrophobic surface).Further study show that, the super hydrophobic surface prepared using patent US2015/0368496A1,
When ultraviolet light intensity brings up to 2W/m2, in the senile experiment of 150 hours, surface contact angle is reduced to 120 °, and surface is dredged
Water hydraulic performance decline.According to super hydrophobic surface prepared by patent US2015/0368496A1, though there is a certain degree of wear resistence,
Patent case 8 shows, even if optimization formula, the friction treatment of 4.5 minutes is carried out to surface, and the super-hydrophobic ability on surface is completely still
Lose.Additionally, above-mentioned formula is mainly used in the anti-thin water ice application of cable surface, and when it is applied to aircraft surfaces, may not necessarily be same
