Description

Have the super-hydrophobic ice-covering-proof aluminum of uneven surface and the surface treatment method of steel
Technical field
The present invention relates to a kind of the have super-hydrophobic ice-covering-proof aluminum of uneven surface and the surface treatment method of steel.
Background technology
The frosting phenomenon extensively is present in the metallic element of refrigeration and cold operation equipment, and for example the wing of the air-coil of heat pump set, aerospacecraft and surface, air-conditioning, refrigerator internal surface etc. have brought harm in various degree for the steady operation of equipment.
The anti-freeze technology in traditional engineering materials surface is utilized machinery or heating technique deicing, ice-melt more, like thermal ice-melting, excess current de-icing, short circuit ice-melt, on-load ice-melt etc.More existing invention technology also are based on the thinking of " ice-melt ", as: adopt high-frequency pulse current to add thermal oscillation the anti-icing of electric line is removed ice-melt, the conductor that the lead of employing and power transmission and distribution together lays generates heat to prevent icing.But these methods can not tackle the problem at its root, and when deicing, need arrestment, and are equipped with special ice removal system and equipment.This has brought inconvenience to production undoubtedly, has also consumed a large amount of energy simultaneously, has increased cost.For this reason, part Study personnel are origin to suppress icing, have explored some and have suppressed icing method.As being coated with at cold surface with wetting ability dope of restraining frost [Okoroafor EU, J Phy.D-App.Phy., 1999,32 (18): 2454-2461; Okoroafor EU, Newborough M, App.Thermal Eng., 2000; 20 (8): 737-758], the thickness that can reduce frost reaches 10-30%, but this coating is thicker, about 0.77mm; Have influence on the cold surface airiness, and the organic composition in the coating is volatile, makes that its work-ing life is lower; The good grade developed a kind of strongly hydrophilic dope of restraining frost among Liu of Beijing University of Technology, and this coating contains absorbent resin, can absorb large quantity of moisture; And the freezing point that sodium-chlor that adds or potassium chloride particle can effectively reduce water; Make the moisture in the absorbing coating keep for a long time not freezing, thereby suppress the appearance of initial hoar crystal, play the effect that presses down frost; But the moisture that this strongly hydrophilic surface absorbs is difficult for volatilization fast; Owing to just reduce the freezing point of water, when temperature is lower, can promote the formation of hoar crystal, the frosting on aggravation surface on the contrary.
Copy to have " lotus leaf effect (Lotus Effect) " special surface microstructure of organism, can construct similar special construction, the metallic surface that obtains having superhydrophobic characteristic in the metallic surface.There are extremely huge application potential and wide application prospect in this super-hydrophobic metallic surface in fields such as self-cleaning, drag reduction, corrosion-resistant, freezings.As inspiration, some hydrophobicity anti-icing coating and coating technique are developed in succession.As with after organosilane and/or fluorine silicon resin, quick-drying solvent, the main body solvent stirring at room; Add polyoxyethylene, silane coupling agent promotor, silicon oxide and/or alumina particle in succession and stir, be coated in specimen surface curing at last and obtain anti-icing coatings, can make frosting degree reduce 40%; But this technology is difficult for applying to some positions of complex-shaped equipment and part; Make that protection is inhomogeneous, and the organic solvent in the coating is volatile, work-ing life is lower; The frosting layer also needs under mechanical vibration, to remove, to some need are anti-freeze but precision instrument, equipment and part that can not vibrate have certain limitation; Through the vacuum evaporation mode, coating n-hexatriacontane hydrophobic layer also can postpone the formation of initial hoar crystal on the feeder cable surface, and the hoar crystal short texture of formation is prone to remove, but it is pointed out that this film coating method need be in vacuum tightness less than 1.3 * 10 -5Vacuum condition under carry out, obviously be difficult for carrying out scale operation.
Research shows [Byeongchul N, Ralph LW, Int.J Heat&Mass Transfer; 2003,46,3797-3808]; The roughness of solid surface can reduce the degree of supersaturation of water vapour; Thereby reduce the nucleation rate and the nucleation rate of the globule, delay the formation of initial hoar crystal, play the effect that presses down frost.Simultaneously, the potential barrier that water repellent surface forms the globule is bigger than hydrophilic surface, so it is little than hydrophilic surface to condense into the quantity of liquid nuclear on the water repellent surface.Therefore, at solid surface, the surface of especially widely used aluminium and steel is constructed roughness and hydrophobicity simultaneously, will more effectively delay the appearance of initial hoar crystal, significantly improves the freezing performance on aluminium and steel surface.But, and do not see as yet that to the surperficial hydrophobicity anti-icing technology of aluminium and steel report is arranged based on this thinking.
Summary of the invention
The present invention provides the treatment process on coarse aluminium of a kind of super-hydrophobic ice-covering-proof and steel surface.
The present invention adopts following technical scheme:
The treatment process on coarse aluminium of a kind of super-hydrophobic ice-covering-proof and steel surface, processed steps is following:
(1) pre-treatment: aluminium flake and steel disc are also dried with acetone, deionized water ultrasonic cleaning successively;
(2) wet-chemical chamber: aluminium flake or steel disc are hung in the closed unit that fills hydrochloric acid soln; Then closed unit is placed constant temperature water bath; Make the hydrochloric acid volatilization under 100 ℃ of boiled water temperatures, and, also dry with flushing with clean water behind taking-up aluminium flake or the steel disc with evaporable salt acid etch aluminium flake or steel disc; The volume(tric)fraction of said hydrochloric acid is 20%-80%, and etching time is 15min-1h;
(3) fluoridation: aluminium flake after the etching and steel disc are put into the encloses container that fills the silicon fluoride hexane solution, and together put into cabinet-type electric furnace 200-300 ℃ of insulation 1-2h down, realize that the silicon fluoride on aluminium flake and steel disc surface is modified; Take out sample subsequently, under 180-300 ℃, in air, be incubated 1-2h, can obtain possessing the aluminium and the steel surface of superhydrophobic characteristic; The frosting experiment on the aluminium of preparation and steel surface shows that there is good anti-icing performance on this surface; The process for preparation of said silicon fluoride solution is: silicon fluoride is dissolved in the normal hexane solvent; The weight percent of silicon fluoride and normal hexane solvent is 1-5%; The 2-4%, the pH value that add silicon fluoride hexane solution weight again are 3 aqueous acetic acid, can use after fully stirring.
The present invention has prepared the super-hydrophobic ice-covering-proof aluminum with uneven surface and the surface of steel.At first, the roughness on aluminium and steel surface can reduce the degree of supersaturation of water vapour, thereby reduces the nucleation rate and the nucleation rate of water droplet, delays the formation of initial hoar crystal, plays the effect that presses down frost.Secondly, there are good ultra-hydrophobicity and very low viscous force in this surface to glassware for drinking water, when contacting with water droplet, has very high contact angle (>150 °) and extremely low roll angle (1 °).Super hydrophobic surface not only can increase the potential barrier that forms the globule; Reduce the quantity that surperficial water droplet condenses into liquid nuclear; Can when contacting, form " air cushion " simultaneously, significantly reduce the real contact area (<10%) of the globule and solid surface at the contact interface entrapped air with water droplet; Thereby when low temperature, effectively reduce the thermal exchange between surface and water droplet; Increase the globule required energy that condenses, finally make water droplet be difficult to condense into karyomorphism and become initial hoar crystal, and be suppressed at the formation and the growth of the frost layer of growing on the initial hoar crystal basis.It is pointed out that water droplet very easily tumbles on this surface because the aluminium and the steel surface of preparation are lower to the viscosity of water droplet; Slight vibration, or even wind might make that all water droplet tumbles, and freezes to form hoar crystal thereby be difficult for absorption; Even form, also very easily landing because viscosity is lower, thus not only played the icing effect that suppresses; Also play the effect of deicing, really realized the anti-icing on aluminium and steel surface.Therefore; The super-hydrophobic ice-covering-proof surface that has certain roughness in widely used aluminium and steel surface preparation; Not only can more effectively delay the appearance of initial hoar crystal; Significantly improve the freezing performance on aluminium and steel surface, can also utilize the low viscosity on surface to come deicing, realize the anti-icing in real aluminium and steel surface.Like this super-hydrophobic ice-covering-proof of preparation on the shell on submarine or naval vessel surface; Automatically cleaning, raising route speed and the resistance to corrosion seawater that not only can keep the surface; Also can make shell under coldcondition, not have icing; Thereby be they under coldcondition, as in the South Pole, the navigation of the arctic or other extremely frigid zones, provide safeguard.
Preparation technology provided by the invention is based on the wet-chemical chamber method; Required starting material are common solvents such as acetone, hydrochloric acid, silicon fluoride, normal hexane, acetic acid; Required equipment is common devices such as Ultrasonic Cleaners, constant temperature water bath, encloses container, cabinet-type electric furnace, and process step and operation of equipment are very simple, and according to production-scale demand; Can meet the demands through suitable adjustment, efficient is high, cost is low.In addition, the treatment process of the anti-icing of this aluminium and steel surface super hydrophobic does not have particular requirement to aluminium and steel itself, and can effectively handle the position that some of complex product are difficult for coating yet.Therefore, the surface treatment method suitability of super-hydrophobic ice-covering-proof aluminum with uneven surface provided by the invention and steel is wider, is prone to industrial applications.
