Description
Technical field
The present invention relates to super-amphiphobic coating preparation field, more particularly to a kind of wear-resisting fluorine silicon resin/composite modified nanometer
SiO2-TiO2Hydridization super-amphiphobic coating and preparation technology.
Background technology
Super-hydrophobic coat refers to coat one or more layers super hydrophobic material in the surface of solids, with high water contact angle (>
150 °) and low roll angle (<10 °), realize the function such as its anticorrosion, waterproof, ice-covering-proof.Super-hydrophobic coat is due to excellent
Hydrophobicity, coating hardware outside, reduce aqueous vapor and surround, anti-corrosion function can be realized；In sleet Snowfall situation
Under, super hydrophobic surface keeps not icing condition or reduces the adhesive force of ice sheet, prevents or delays powerline ice-covering, in wire table
Face prepares the super-hydrophobic coat with durability anti-icing performance, is to realize actively ice-covering-proof economically viable technology.With people
To new material exploitation require gradually step up, the material only with single super-hydrophobicity can not meet the need of people
Ask, therefore multi-functional super-amphiphobic material is arisen at the historic moment.The design of super-double-hydrophobic surface is based primarily upon following two principles:When according to
Migrated by fluorine atom to surface, make surface that there is extremely low surface energy, greasy dirt is not easy to bond on its surface；Second, rely on photocatalysis
Degradation, make organic oil stain decomposition.The key for preparing super-double-hydrophobic surface is low-surface energy substance and surface roughness.It is super double
Open coat can be realized super-hydrophobic with superoleophobic function simultaneously, can significantly reduce the surface free energy of solid, have it is anti-pollution,
The characteristic such as automatically cleaning, hydrophobic, oleophobic, lower resistance, low friction, super-amphiphobic coating is coated on power transmission and transforming equipment insulator, can
Effectively reduce filthy attachment and keep drying not wetted state, reinforced insulation performance, prevent pollution flashover accident.
But super-hydrophobic or super-amphiphobic coating is extended in practical application, still suffer from larger obstacle：(1) prepare at present
Super hydrophobic surface coarse structure is unstable, resistance and fingerprint resistance or wears no resistance, and super-hydrophobic phenomenon can be caused to disappear when being worn, this
Be due to super hydrophobic surface intolerant to greasy dirt, by oil pollution, so as to cause contact angle to reduce；This surface wear can cause micro-
When seeing structure by destroying, surface roughness can reduce, furthermore, surface abrasion may result in the low-surface energy substance on surface
Chemical composition changes, and causes the hydrophobic performance of super hydrophobic surface to reduce or lose.But surface roughness is unstable
The binding strength that basic reason is between micro-rough structure and substrate, micro-rough structure is mutual is low, and coarse structure is easy
It is destroyed, Given this there is not the super-hydrophobic coat for obtaining broad practice also at present；(2) super-double-hydrophobic surface usually requires to hold high
Expensive plant equipment, preparation technology is complicated, and production cost is higher, significantly limit the application of super-hydrophobic coat；(3) super-amphiphobic
Coating usually requires being applied in combination, it is necessary to special complete curing agent is used in combination of two layers of bottom surface paint, and makes in actual applications
Maintenance must be repaired to be difficult to；(4) coating needs thermally treated, and crosslinking curing temperature is higher, is entered in actual applications using high temperature
Row curing of coatings undoubtedly adds difficulty of construction.
Fluorine silicon resin is organically combined the weatherability of the low-surface-energy of fluororesin and organic siliconresin, be prepare it is super double
A kind of typical low-surface-energy material of open coat.But the research on fluorine silicon super-hydrophobic coat is limited to single nanometer mostly
