Test example
The preparation of coating:
(1) coating prepared by embodiment 1 and embodiment 3 is sprayed one deck under the pressure of 0.6 ~ 0.8MPa, dry film film thickness controls at 35 ~ 40 μm, unsuitable blocked up, and normal temperature self-drying 24 hours is to be measured, dry 1 hour to be measured;

The object of oil transportation drag reduction is to reduce skin friction coefficient, and coefficient is exactly relevant with medium contact area, relative movement between liquid and solid also depends on surface tension, be 18N/m by the surface tension measuring embodiment 1 ~ embodiment 3 coating, and then explain why all embody very high contact angle at water oil.First physical process forms a large amount of nanometer micropores by the spatial configuration of coating in essence and causes water can not enter guarantee liquid interface and be coated with interlayer leaving a part of rarefied air, due to ultralow surface tension can make oil body on surface with very low resistance quickly through, experimental result display tests through the decay of 3 years the contact angle still keeping 150 °, because current domestic in be all phoenix feathers and unicorn horns more than 6 months, the popularization of achievement will be the important topic in the coming years.
Fig. 5 display surface tentacle is all reunited, and be complete spread apart, unimolecular layer can not embody completely, and its effect is slightly poor.
Fig. 6 display surface uniformity, tentacle distribution is consistent, and monomolecular coating is formed, and effects on surface energy tension force reduces synergy.
The present invention is mainly the distribution of the host molecule structure of draft reduction material, common silane, perfluor analog assistant can reduce coating surface tension really to realize drag reduction, but majority has the degree of branching of a large amount of by product and principal product high, effective content is truly not high, and form almost not having of unimolecular layer perfluor base, correlative study is had although domestic, but all can not realize commercialization, and the present invention to be exactly the problem that should solve unimolecular layer realize commercialization is simultaneously worth, by reducing frictional coefficient, reduce transport resistance, improve the persistence of this special drag-reduction effect of coating, suppress the deposition of incrustation scale, improve transport efficiency at cooperation liquid pipe transportation technology simultaneously, reduce actual operation cost, and then realize the new ideas of pipeline corrosion protection.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
