Description
Technical field
The present invention relates to a kind of superhydrophobic fabrics and its preparation method and application, specifically prepare one kind using infusion process and exist
The fabric of ultra-hydrophobicity is all had in air and in oil, to expand the use scope of superhydrophobic fabric.
Background technique
Superhydrophobic fabric is increasingly subject to the favor of people, is current function by performances such as its unique automatically cleaning, antipollutions
One of the hot spot of energy textile.Researcher has passed through nanometer particle load method (Chinese invention patent CN102321974A), has connect
Branch polymeric method (Adv. Mater. 2010,22,5473-5477), sol-gel method (Chinese invention patent
) etc. CN102277720A it is prepared for a large amount of superhydrophobic fabrics.However, these preparation superhydrophobic fabrics mechanical endurance compared with
Difference, after by friction, even finger is touched, fabric is easy to lose ultra-hydrophobicity.It is durable in order to solve superhydrophobic fabric machinery
Property difference problem, researchers at home and abroad have carried out a series of exploratory developments.Such as: Chinese invention patent CN103074768A is logical
It crosses lye etching and low-surface energy substance modification is prepared for the super-hydrophobic dacron of wash resistant and rub resistance.S. Seeger etc.
People is by being prepared for stable ultra-hydrophobic fabric in fabric surface growth in situ silicon nanowires.But these methods also have
Disadvantage, such as preparation process are relatively complicated, need expensive chemicals and particular instrument.Therefore, develop a kind of simple, economical
Method seem particularly significant to prepare durable super-hydrophobic property fabric just.
The ring that when if superhydrophobic fabric is in oil environment still there is ultra-hydrophobicity superhydrophobic fabric will be greatly improved
Border durability, and the added value and practicability of superhydrophobic fabric can be greatly improved, surpass its application range to widen.But mesh
Preceding resulting fabric only has ultra-hydrophobicity in air, and there are no the research reports about superhydrophobic fabric in oil.Cause
This, invention in the oil superhydrophobic fabric be it is extremely necessary, also there is important meaning for the promotion and application of superhydrophobic fabric
Justice and have potential great market.
Summary of the invention
The present invention solves the problems, such as that superhydrophobic fabric stability exists the prior art, provides a kind of durable super-hydrophobic property and knits
Object and its preparation method and application, it is the method simple process, low in cost, reproducible.
There is ultra-hydrophobicity fabric and its preparation method and application in the oil it is a further object of the present invention to provide a kind of,
To improve the application range of superhydrophobic fabric.
The preparation method of the fabric of ultra-hydrophobicity is all had in a kind of air provided by the present invention and in oil, including such as
Lower step:
The preparation of A alkylation silica:
Under room temperature, organochlorosilane is added dropwise into the toluene solution uniformly containing silica dioxide granule, then magnetic agitation
6h；
To after reaction, centrifugal treating simultaneously removes supernatant, then being removed using ethanol washing product unreacted is had
Machine chlorosilane, again centrifugal treating obtain alkylation silica dioxide granule after desciccate at 70 DEG C；
The mass ratio of silica used, organochlorosilane and toluene is 1:0.5 ~ 1:35 in the step；
Organochlorosilane used is any one in trichlorine octadecylsilane or trim,ethylchlorosilane in the step；
The preparation of B alkylation silicon dioxide-poly tetrafluoro wax toluene solution:
Silica dioxide granule will be alkylated and Polytetrafluoroethylene emulsion particle is added in toluene, magnetic agitation 1h makes to be alkylated under room temperature
Silica and Polytetrafluoroethylene emulsion are uniformly dispersed in toluene, obtain alkylation silicon dioxide-poly tetrafluoro wax toluene solution；
Alkylation silica used in the step, Polytetrafluoroethylene emulsion and toluene mass ratio be 4~1.5:1:85；
The preparation of C superhydrophobic fabric:
Soak the fabric into alkylation silicon dioxide-poly tetrafluoro wax toluene solution and take out after 1 ~ 30min, then 108 ~
After drying removes toluene at 150 DEG C, the fabric that ultra-hydrophobicity is all had in air and in oil is obtained.
It is preferred that the partial size of silica used in step A is 5~70 nanometers.
It is preferred that the partial size of Polytetrafluoroethylene emulsion used in step B is 5~15 microns.
It is preferred that the drying temperature of step C is that effect is optimal at 130 DEG C.
It is preferred that any one in dacron fabric or cotton fibre fabric of the fabric used selected from commercialization.
It is super the present invention also provides being all had in a kind of air being prepared using made as described above method and in oil
The fabric of hydrophobic performance.
The fabric that ultra-hydrophobicity is all had in air prepared by the present invention and in oil can be applied in water or in oil.
The superhydrophobic fabric as made from this method, contact angle of the droplet on its surface is 155.5o~158 o, roll angle
It is 5 o~7 o。
The surface free energy of fabric surface can be reduced the principle of the invention lies in Polytetrafluoroethylene emulsion and alkyl can be enhanced
Change the adhesive force between silica and fabric fibre.Roughness and further can be improved in alkylation silica
Reduce the surface energy of fabric surface.The roughness of the too high levels of Polytetrafluoroethylene emulsion, fabric surface will reduce, and fabric cannot achieve sky
Gas neutralizes ultra-hydrophobicity in oil.The too high levels of silica are alkylated, the adhesive force decline between fabric fibre is knitted
Object cannot achieve lasting ultra-hydrophobicity.
After fabric surface impregnates Polytetrafluoroethylene emulsion and alkylation silica, it is heated.Heat treatment temperature
Degree, which is higher than 108 DEG C of fusing point of Polytetrafluoroethylene emulsion, makes its melting, and such Polytetrafluoroethylene emulsion will be wrapped in fabric fibre melt surface
It is alkylated silica, thus improve Polytetrafluoroethylene emulsion and be alkylated adhesion strength of the silica on fabric fibre surface, this
Fabric prepared by sample will show stable ultra-hydrophobicity.When heating temperature is lower than the fusing point of Polytetrafluoroethylene emulsion, although
Fabric can show ultra-hydrophobicity, but its ultra-hydrophobicity and unstable, be easy to lose under the effect of external force.
The positive effect of the present invention is that:
1, superhydrophobic fabric of the invention through finger touch, blade scribing and with after 30 opposite grindings of sand paper (pressure at right angle,
Friction velocity), 150 are still greater than with the contact angle of water droplet o。
2, superhydrophobic fabric preparation method simple process of the invention, preparation cost is cheap, does not need specific instrument sets
It is standby.
3, superhydrophobic fabric preparation method of the invention is not limited by fabric substrate type, to cotton, terylene and other fabrics
All adapt to.
4, superhydrophobic fabric of the invention still has ultra-hydrophobicity in oil environment.
