Description
Technical field
The present invention relates to a kind of hydrophobic film material, relate in particular to a kind of super-hydrophobic polypropylene film, belong to the based superhydrophobic thin films technical field.
Background technology
PP SHEET FOR OPP TAPE has application widely owing to have characteristics such as nontoxic, tasteless, that cost is low, the transparency is good in packing, industrial, agricultural and daily life.Yet present business-like PP SHEET FOR OPP TAPE does not have self-cleaning property.
Owing to receive the inspiration of lotus leaf effect, in recent years, caused extensive interest in the industry greater than the preparation and the research of 150 ° super-hydrophobic macromolecule membrane with the contact angle of water.Because the contact area of liquid on based superhydrophobic thin films is very little, can suppress phenomenons such as surface oxidation, burn into frost, conduction of current effectively; Therefore, based superhydrophobic thin films all is with a wide range of applications in fields such as outdoor antenna, exterior coating, steamer, biologic medical apparatus, microfluid, windshields.
Obviously, if give the PP SHEET FOR OPP TAPE super-hydrophobicity,, will enlarge the use range of PP SHEET FOR OPP TAPE greatly with the self-cleaning property and the water-repellancy that obtain the not available excellence of general thin.Yet, super-hydrophobic polypropylene film is really used in actual industrial and agricultural production and daily life, the preparation of super-hydrophobic polypropylene film is crucial, also is the basis.In recent years; Developed the technology of a large amount of preparation based superhydrophobic thin films, like sol-gel method, fluorinated coating method, chemical Vapor deposition process, electrochemical deposition method, polyelectrolyte alternating deposit method, anonizing, mechanical stretching method, plasma method, chemical method for etching, electrostatic spinning method etc.Yet, existing these methods or expensive material such as the extremely low fluorinated siloxane of surface energy of use, or need special processing units such as plasma processing equipment or complicated technological process, thereby cost is higher, is difficult to industrialization.Therefore inventing a kind of simple and low super-hydrophobic polypropylene film of preparation cost is necessary.
Like " a kind of super-hydrophobic polypropylene film and preparation method thereof " that Chinese patent provided, its Granted publication number is CN101531764B, makes PP SHEET FOR OPP TAPE through the method for in Vestolen PP 7052 solution, adding acetone in this patent; Utilize acetone to induce Vestolen PP 7052 solution to produce microphase-separated; Form irregular structure, thereby obtain super hydrophobic surface, the surface of the PP SHEET FOR OPP TAPE that it makes is poroid crystalline network class Bird's Nest structure; The controllability of its preparation is relatively poor, and process is more complicated also.

The superhydrophobic property of super-hydrophobic polypropylene film of the present invention is stable, is that 0～40 ℃, relative humidity are to place 2 years in 20%～90% the environment in TR, and superhydrophobic property does not change.
In above-mentioned a kind of super-hydrophobic polypropylene film, described super-hydrophobic polypropylene film adopts the following step to be prepared from:
(1) take by weighing a certain amount of polypropylene granules, it is dissolved in the solvent, forming concentration is the Vestolen PP 7052 solution of 1～100mg/ml;
(2) with above-mentioned Vestolen PP 7052 solution casting in substrate, be 75～85% in relative humidity, ethanol vapor concentration is that drying obtains super-hydrophobic polypropylene film under 5～20% the environment.
The present invention adopts polypropylene granules as starting material; Form uniform solution in the solvent through being dissolved into; Be 75～85% in relative humidity again; Ethanol vapor concentration is a drying and volatilizing solvent under 5～20% the environment, in drying process, utilizes airborne alcohol vapour and water vapour to penetrate into the Vestolen PP 7052 solution surface and forms honeycomb structure, thereby obtain super hydrophobic surface.The present invention adopts casting method in addition, can prepare large-area PP SHEET FOR OPP TAPE.Relative humidity is extremely important among the present invention, under the condition of above-mentioned relative humidity, can further induce microphase-separated to form similar lotus leaf surface nanostructure, and be difficult to obtain super hydrophobic surface under other the relative humidity condition.
In above-mentioned a kind of super-hydrophobic polypropylene film, the temperature when dissolving in the step (1) is 10～140 ℃.
In above-mentioned a kind of super-hydrophobic polypropylene film, the solvent described in the step (1) is one or more the mixing in YLENE, toluene and the benzene.
In above-mentioned a kind of super-hydrophobic polypropylene film, the substrate described in the step (2) is a kind of in glass, pottery, metal, the silicon wafer.
In above-mentioned a kind of super-hydrophobic polypropylene film, the temperature in the step (2) when dry is 80～120 ℃, and be 2～30 hours time of drying.
Compared with prior art; The superhydrophobic property of super-hydrophobic polypropylene film of the present invention is stable; Preparation is convenient, and technical process is simple, favorable reproducibility, need not any expensive device, also do not need the complex chemical treatment process, and cost is lower; Have the good industrial application prospect, be fit to large-scale industrial production.
