Description
Technical field
A kind of hydrophobic fusion spray cloth with rough surface of the present invention and preparation method thereof
Background technology
20 century 70s, botanist's William's Bartelot of Univ Bonn Germany proposes lotus leaf effect.Lotus leaf
Effect is primarily referred to as lotus leaf surface to be had super-hydrophobic (superhydrophobicity) and self-cleaning (self-cleaning)
Characteristic.Because lotus leaf has hydrophobic surface, the rainwater on blade face that falls can form the globule, water and leaf because of the effect of surface tension
The contact angle in face is more than 150 °, as long as blade face is slightly tilted, the globule will be rolled off blade face.Bartelot finds under the microscope,
There are one layer of fine hair and some small wax particles in the surface of lotus leaf, and water will not be to lotus leaf on these nano level molecules
Other directions of surface are spread, but form droplet one by one.Knowable to lotus leaf effect water repellent principle, with height water repellent energy
The material of power must possess two primary conditions：Material surface must have basic water repellency first；Have simultaneously certain
The surface of roughness.
It is no lack of the example of super hydrophobic surface, such as leg of lotus leaf, Rice Leaf, the wing of cicada and water skipper in nature.Seek
The problem of interest with the new material always people that possess ultra-hydrophobicity are developed, is also bionics field for many years
One of focus of research.Superhydrophobic fabric enjoys the green grass or young crops of people because of properties such as excellent anti stick, antifouling and automatically cleanings
Look at, can be widely used in rain-proof/antifouling outdoor clothes, diving suit, indoor decorative fabric, camping tent, military battle-dress uniform, industrial
The aspects such as waterproof cloth, medical and health textile.
, as the highly crystalline polymer of nontoxic, odorless, tasteless milky, it is particularly stable to water, in water for polypropylene sheet
In water absorption rate be only 0.01%, hardly absorb water.And the fusion spray cloth with polypropylene as primary raw material, fibre diameter can reach
1~5 micron, these superfine fibres with unique capillary structure can increase the quantity and surface area of unit area fiber,
So that fusion spray cloth is while with good gas permeability, also with good water repellency.
In recent years, water-repellent breathable fabric demand in industry and life is more and more, and researchers are using at various methods
Reason fabric face, in the hope of reaching preferable hydrophobic permeable effect.The existing super-hydrophobic treatment to fusion spray cloth, mainly in cloth table
Face coats or one layer of super-hydrophobic coat of dipping, cloth surface is had low-surface-energy, while reduce fusion spray cloth aperture, so that molten
Spraying reaches super-hydrophobic effect.But these processing methods often occur that fusion spray cloth gas permeability is deteriorated, and cloth cover is hardened, and thickness becomes
Big problem.
Many studies have shown that, it is the major reason to form super-hydrophobic effect with micro-nano coarse structure surface.Improve material
Expect the roughness on surface, can to a certain extent obtain bigger contact angle, obtain more preferable hydrophobic effect.
The content of the invention
To be solved by this invention is low fusion spray cloth porosity caused by common hydrophobic processing method, and poor air permeability is thick
Degree is big, the hard problem in surface.
In order to solve the above problems, the invention provides a kind of hydrophobic fusion spray cloth with rough surface, it is characterised in that
The fusion spray cloth surface has concavo-convex coarse structure, assigns the more preferable hydrophobic performance of fusion spray cloth.
Preferably, the fibre diameter of the fusion spray cloth is 2-4 μm, and surface roughness parameter Ra is 0.03 μm~0.3 μm.
Preferably, the material of the fusion spray cloth is any one in polypropylene, polyester, polyamide and PLA.
It is highly preferred that the material of the fusion spray cloth is polypropylene.
Present invention also offers the preparation method of the above-mentioned hydrophobic fusion spray cloth with rough surface, it is characterised in that specific
Step is as follows：
The first step：Fusion spray cloth is clipped in the screen cloth that two-layer mesh number is 300-700 mesh；
Second step：By hot rolling in the screen cloth/fusion spray cloth of the first step/screen cloth feeding hot-rolling mill；
3rd step：Fusion spray cloth after second step hot rolling is taken out from two-layer screen cloth, obtaining final product surface has concavo-convex coarse knot
The hydrophobic fusion spray cloth of structure.
Preferably, the material of screen cloth is stainless steel or fibre fabric in the first step.
Preferably, the hot-rolling mill in the second step is flat board hot-rolling mill or roller-type hot rolling mill；When using flat board hot rolling
During machine, its pressure is 2-4MPa, and the time is 10-20s；When using roller-type hot rolling mill, its line pressure is 1.0 × 103-3.0
×103N/cm, speed is 10-70m/min.
Preferably, fusing point 15-50 DEG C of the hot-rolled temperature in the second step less than the polymer that fusion spray cloth is used.
, by padding screen cloth in the hot rolling, while fusion spray cloth surface hairiness is offseted, formation is concavo-convex not for the present invention
Flat coarse structure, substantially increases the surface roughness of fusion spray cloth, increases the contact angle of fusion spray cloth so that molten after hot rolling
Spraying has more preferable hydrophobic effect.
Specific embodiment
To become apparent the present invention, hereby with preferred embodiment, it is described in detail below.
The present invention chooses the arithmetic mean deviation Ra of profile as the evaluating of fusion spray cloth surface roughness, the definition of Ra
For：In a sample length, on profile each point to center line apart from absolute value average arithmetic deviation.It is aobvious using laser co-focusing
Micro mirror obtains the surface scan image of sample, and the height coded image of sample is obtained with computer image processing technology, then uses tricks
Calculation machine assisted image analysis technology obtains the contour curve and surface roughness Ra value of sample.
