Description
Technical field
The invention relates to a kind of wear-resisting ultra-hydrophobic papers and preparation method thereof, are related to nanotechnology, functional paper
Field.
Background technique
The water contact angle that super hydrophobic material generally refers to material surface is greater than 150 ° and material of the roll angle less than 10 °.It is super
Hydrophobic phenomenon is determined by Wettability of Solid Surface, and surface of solids wettability is its important property, mainly by solid
This 2 factors of surface microstructure and chemical property influence, and liquid is in the surface of solids when wettability of solid leads to common static
Contact angle characterizes, and when contact angle is greater than 150 °, the surface of solids shows super-hydrophobicity.Lotus leaf, gecko foot in nature
The animals and plants organ such as bottom, watermelon leaf and cicada's wings all has a super-hydrophobicity, super hydrophobic surface have good anti-ice jelly, anticorrosion,
The performances such as drag reduction, biological assay.By the inspiration of nature super hydrophobic surface specific function, scientific research personnel prepares various performances
Super hydrophobic material is applied to the fields such as automatically cleaning, water-oil separating, anti-rotten candle, surface motions drag reduction.Super hydrophobic surface is constructed to need
Two conditions: micro-/to receive the building and low-surface energy substance of surface texture.The micro-nano structure of lotus leaf surface complexity and low surface
The main reason for energy waxy substance is super-hydrophobic automatic cleaning, by the inspiration of lotus leaf effect, preparing super hydrophobic surface, there are two types of approach:
It is a kind of to construct certain rough surface on substrate, then modified with low-surface-energy material；Another kind is in low-surface-energy material
Surface constructs suitable coarse structure.The method for being usually used in constructing ultra-hydrophobic paper has phase separation method, wet etching, infusion process etc..
Paper has the excellent characteristic such as cheap, from a wealth of sources, nontoxic, pollution-free, applies pole on packaging material
It is extensively.Since paper fiber contains hydrophilic functional group, there is good hydrophily, it is hygroscopic in a humid environment, it reduces
The intensity of paper loses its use value.If moisture resistance, the self-cleaning property of paper can be improved to paper surface imparting superhydrophobic energy
And other characteristics etc., be conducive to the application field for expanding paper.
For paper base super hydrophobic material as a kind of new material with very big practical potentiality, it can overcome fiber easily to inhale
It is wet, use limitation caused by stability is poor etc., and flexibility difference that can overcome traditional waterproof material etc. uses disadvantage.So
And show some drawbacks that super hydrophobic material is also inherited while superiority: binding force is poor between hydrophobic layer and substrate,
Preparation process is cumbersome.Super hydrophobic material used in everyday will receive the mechanical failures such as stretching, bending, shearing to which hydrophobic layer occur
It is fallen off between substrate, falling off for hydrophobic layer will lead to the hydrophobicity decline of material, to influence the reuse of material
Property.The scale application of super hydrophobic surface is always by limitations such as the weak mechanical endurance of its own, Gao Chengben, difficult maintenances.Closely
Nian Lai, in order to overcome the problems, such as this, people start the mode for considering to combine using organic and inorganic, by inorganic super-hydrophobic nano grain
Son is bonded on organic resin, to improve its wearability, to expand its application.
Nano silica is a kind of environmentally friendly material, its structure is special, a large amount of activated silica hydroxyl is contained on surface
Base, specific surface area are very big, therefore show some special physicochemical characteristics, such as special photoelectric characteristic, high Magnetoresistance Phenomena
With nonlinear resistance phenomenon etc..In addition, nano-silicon dioxide particle has surface-interface effect, small-size effect, quantum size
Effect and macro quanta tunnel effect, and still there is very high intensity, toughness and good stability at high temperature, thus it is wide
It is general to be applied to the fields such as coating, rubber, pharmaceutical carrier.But nano silica is higher so that very due to surface free energy
It is easy to reunite, it is compatible as being difficult when functional stuffing filled polymer matrix between inorganic phase and organic phase, lead to nanometer
Silica disperses unevenly, the lot of advantages of nano silica to be made to be difficult to give full play in organic phase.For this reason, it may be necessary to right
Nano silica carries out surface physics or chemical modification.By certain technique, make the silicon hydroxyl of group and silica surface
Base and unsaturated bond reaction, the various active groups needed for introducing on its surface make so as to improve the performance of nano silica
The content of its surface silanol group reduces or eliminates, and improves the compatibility of nano silica and organic polymer matrix.
Preparation super-hydrophobic paper at present mainly carries out modifying super hydrophobicity in paper surface.There is researcher to prepare one kind
Novel has super-hydrophobic and super-oleophilic matter super hydrophobic functional paper (SFP).Paper handkerchief is immersed and contains silica nanometer
The solution of grain and dimethyl silicone polymer (PDMS), makes nano SiO 2 particle reunite on paper handkerchief, increases surface roughness,
And solidify PDMS drop low-surface-energy, super hydrophobic functional paper SFP is thus made.Number of patent application is 200710192404.5 a kind of super
It is mentioned in hydrophobic paper and preparation method thereof patent, first a certain amount of paraffin is dissolved in dehydrated alcohol, hot water is added thereto
And it stirs, then paper is impregnated in resulting paraffin solution, ultra-hydrophobic paper is made.But paper is vulnerable to environment made from the method
Temperature change influences ultra-hydrophobicity, and stability is poor；Number of patent application is a kind of AKD modified Nano two of 201410487707.X
It is mentioned in the paper that silica is manufactured paper with pulp and preparation method thereof patent, first impregnates filter paper with certain density aluminum sulfate solution, then will
Filter paper after immersion lifts dipping for several times in the AKD- ethanol solution containing nano silica, and gained paper has good
Hydrophobic performance.But paper obtained does not achieve the effect that super-hydrophobic；Number of patent application is 201710816908.3 a kind of super
It is mentioned in hydrophobic paper and preparation method thereof patent, it is modified to carry out hydroxylating to paper first；Using plasma etching method to paper
It performs etching；Plasma pretreatment is carried out to paper with Ar gas source；Using plasma chemical vapour deposition technique is in paper table
Face deposits based superhydrophobic thin films.Gained paper has the advantages that certain intensity and scratch-resistant, but preparation process is at high cost, it is difficult to do
To industrialized production.
To sum up, the preparation process of the super-hydrophobic paper of the prior art is relative complex, the cost is relatively high, most of super-hydrophobic
Paper scraping and wiping resistance performance is poor, and super-hydrophobic stability is poor, and existing super-hydrophobic paper is in addition to having certain hydrophobic performance
Outside, there is no other additional properties.
