Description
Technical field
The invention belongs to ice-removing and ice-preventing fields, and in particular to a kind of aircraft outer surface ice-removing and ice-preventing liquid and preparation method thereof.
Background technique
Under cold wet weather conditions, when aircraft is static its surface easily freeze or formed ice and snow accumulation.These accumulations
Object not only will increase the weight of aircraft, but also aircraft surfaces can be made to become coarse, resistance increase, lift when causing to take off
Reduce, causes to seriously threaten to flight safety, easily lead to aircraft accident.Therefore, international airline standard provides, it is necessary to remove and fly
Aircraft, which could depart from port, after the ice and snow accumulation of machine surface takes off.Although having developed a variety of aircraft surfaces de-icing methods, such as machine at present
Tool deicing, electrical heating deicing, using ice-covering-proof material etc., but using it is most extensive, most effective be still airplane deicing, especially
It is non-Newtonian ice-removing and ice-preventing liquid.Non-Newtonian ice-removing and ice-preventing liquid can not only effectively remove the ice of aircraft surfaces, snow accumulation object, also
Airframe icing can be prevented within a certain period of time.Currently, international airline generally use water soluble polymer thickening alcohol/
Aqueous mixtures prepare non-Newtonian ice-removing and ice-preventing liquid, these polymer include artificial-synthetic copolymer and natural polymer, such as gather
Acrylic acid and its derivative, xanthan gum, guar gum, cellulose etc..It, largely can be after ice-removing and ice-preventing liquid is sprayed on aircraft surfaces
By stripping during aircraft high-speed flight, but still had less in some more covert places (such as the positions such as wing, elevator)
Amount residual.These remaining polymeric liquids easily form hydrated gel, cause a hidden trouble to flight safety.On the other hand, existing
Ice-removing and ice-preventing liquid would generally undergo high speed shear in preparation, transport and operation process, cause centainly to polymer molecular chain
The degradation of degree, and then reduce the performance of ice-removing and ice-preventing.
How being greatly lowered, even avoiding use of the polymer in aircraft deicing anti-freeze fluid is effectively to solve above-mentioned ask
The method of topic.The patent application of Publication No. CN105199671A discloses " a kind of to be increased by low poly-cationic surfactant
Thick anti-freeze fluid and preparation method thereof " obtains a kind of anti-freeze fluid based on low poly-cationic surfactant.However, it is used
Cationic surfactant need under a high concentration condition additional inorganic salts or organic salt can just play the role of increasing stick, obtain it
Described non-Newtonian anti-freeze fluid.The addition of salt significantly increases the hidden danger to body surface corrosion, and be easy to cause
Anti-icing liquid system it is unstable, influence safety in utilization.The patent application of Publication No. CN106883819A discloses a kind of " base
In the ice-removing and ice-preventing liquid and preparation method thereof of overlength chain Surfactant Used in Viscoelastic Fracturing Fluids ", it has obtained a kind of living using overlength chain surface
Property agent increasing stick aircraft deicing anti-freeze fluid, but used surfactant needs artificial synthesized, and preparation process is complicated, and is made
Raw material overlength chain organic acid is expensive.In addition, its used surfactant concentration is higher, further increases and remove
The cost of ice anti-freeze fluid.
