Description
Technical field
Invention relates to technical field of coatings, especially a kind of super-amphiphobic coating.
Background technology
Super-amphiphobic material refers to that various aqueous and oiliness drop is spherical on surface, and contact angle is more than 150 °.Super-amphiphobic material
The coating made, has the excellent properties such as automatically cleaning, anti-adhesive, anticorrosion, drag reduction.Therefore, super-amphiphobic coating can be applicable to build
Build the fields such as beyond the region of objective existence wall, vehicle glass, ship and naval vessels surface, satellite antenna, electric-device housing.This type coating at present
Generally preparation technology is loaded down with trivial details, needs to prepare special structure on certain material, and cannot realize most oiliness drops
Fuel shedding quality；In addition, poor wearability and stability also limit the commercial Application of existing super-amphiphobic coating.
Summary of the invention
Present invention aim to overcome that the deficiencies in the prior art, it is provided that a kind of easily prepared, oleophobic performance more preferably, and has
Excellent wearability and the novel super-amphiphobic coating of stability.
Invention solves its technical problem and be the technical scheme is that a kind of super-amphiphobic coating, including bed material and liftout, and should
Bed material by weight proportion by 0.5-5 part polytetrafluoroethylene powder, 3-4 part ammoniacal liquor, 30-50 part ethanol, 3-5 part tetraethyl orthosilicate and
0.15-0.25 part silicon fluoride form, this liftout by weight proportion by 0.8-1.2 part copolymer from vinylidene fluoride and hexafluoropropylene,
0.3-0.5 part silicon fluoride and 42-52 part dimethylformamide composition.
According to another embodiment of invention, farther include, ammoniacal liquor used, ethanol, tetraethyl orthosilicate and dimethyl methyl
Acid amides is SILVER REAGENT.
According to invention another embodiment, farther include, the average-size of this polytetrafluoroethylene powder be 100 nanometers extremely
10 microns.
The beneficial effect of the invention is, it is super that this super-amphiphobic coating has the tradition such as super-hydrophobic, antifouling, freeze proof, antiseized, drag reduction
Outside the characteristic of hydrophobic material, there is the premium properties such as acid-alkali-corrosive-resisting, friction resistant, life-span length simultaneously.
Detailed description of the invention
