The preparation method of oleophylic lubricant coating.
Background technology
Super hydrophobic surface is in automatically cleaning, water-oil separating, anticorrosive, anti-icing, antifog, antifouling, fungi-proofing, antireflection and drag reduction etc.
Aspect has a wide range of applications potentiality.Sol-gal process, photoetching process, chemical corrosion method, chemical vapor deposition, mould are developed
The multiple technologies such as plate method and dip coating methods manufactures super hydrophobic surface.Yet with most method, there is complexity consumption
When, the problems such as needing expensive equipment and base material species limited, it is difficult to for manufacturing super hydrophobic surface on a large scale.Simply
Brushing, dip-coating and spraying method can overcome drawbacks described above well, but the micro-nano structure that manufactured surface has easily is broken
It is bad, so as to lose super-hydrophobicity.It is to solve that coating, which is adhered in substrate to strengthen the firm wearability of coating, using adhesive
The important method of this problem, is widely paid close attention to.In the operating process of reality, one layer of glue can be first coated in substrate
Glutinous agent, then coating process, but this two steps finishing time and effort consuming, large-scale application are restricted.Adhesive is blended in painting
Disposable painting, which is attached in substrate, in material can efficiently reduce the operating time, be advantageous to large-scale application.For the hydrophobic of enhancing coating
Property, the fluorination material of low-surface-energy is often added into coating, but fluoride is not only expensive, is also easy to accumulate in vivo
It is tired, human health is influenceed, also there is very big harm to environment.Therefore, cheap, environmentally friendly low-surface energy substance such as alkyl silicon
Alkane and Long carbon chain organic matter are favored by people.
In actual application, super-hydrophobic coat surface is easy to lose automatical cleaning ability after being polluted by the oil, although system
This problem can be overcome by making super-double-hydrophobic surface (super-hydrophobic superoleophobic), but is for example needed oil lubrication to realize in some specific areas and subtracted
The bearing that rubs, gear, chain etc. do not apply to simultaneously.In addition, the manufacture on nearly all super-amphiphobic coating surface is required for using at present
Fluorination reagent, it is unfavorable for environmental protection.Few document reports are prepared not fluorine-containing and robust super-hydrophobic super using one-step method
Oleophylic lubricant coating, and this coating can possess self-cleaning function in atmosphere, in oil or after being polluted by the oil.
Super oleophylic lubricant coating has special application in many fields.In mechanical field, some machine components such as axle
Hold, gear, chain, the work such as worm screw when need to add lubricating oil, to realize the lubrication antifriction of working surface.Led in anticorrosion
Domain, air and moisture can be completely cut off well by the metal surface of oil lubrication, prevent the generation of electrochemical reaction, to reach anticorrosion
Purpose.Meanwhile if super oleophylic lubricant coating be also equipped with self-cleaning function will have in these areas widely application before
Scape.
The oil spill disaster for increasing and taking place frequently of oily waste water causes water-oil separating in world wide in industry, life
Inside all suffer from huge challenge.Super-hydrophobic super-oleophylic coating surface has very big application potential in terms of water-oil separating, but
The problems such as reducing there is separative efficiency after reuse, it is difficult to be carried out continuously efficient profit point in actual application
From.
A kind of firm wear-resisting super-hydrophobic super-oleophylic lubricant coating is prepared using simple, environment-friendly technical method, no
It is only capable of solving the problems, such as that surface is dipped in oil or loses automatical cleaning ability after being polluted by the oil, moreover it is possible to realizes needed for some special surfaces
Oleophylic lubricating function, and the water-oil separating for continuous high-efficient is significant in large-scale practical application.
