Description
Technical field
The present invention relates to super hydrophobic surface processing technology field, particularly relate to a kind of vehicle glass superhydrophobic films layer and
Its preparation method.
Background technology
Contact angle is that the one of material surface wettability is measured by water, and wettable surfaces has relatively small contact angle, i.e.
Show hydrophilic；Non-wetting surface has relatively large contact angle, i.e. show hydrophobicity (also known as hydrophobicity, scold water
Property).At present, for improving overcast and rainy driving degree of getting a clear view, on market, existing vehicle glass hydrophober product is sold, this product master
Be used for reducing glass surface energy, the water droplet on its surface of landing under wind-force effect can quickly landing, but in little rainy day and low
In the case of speed travels, glass surface can be covered by thickly dotted small water droplet and reduce glass transmission, for safe driving
Bring hidden danger, prepare superhydrophobic films layer on vehicle glass surface and can eliminate this hidden danger.
Super hydrophobic surface water contact angle is more than 150 °, it is thus achieved that super hydrophobic surface generally from material surface microstructure and
Two aspects of chemical composition are set about, it is however generally that, the more smooth surface exhibits in coarse surface goes out higher hydrophobicity.The most
Develop multiple method and there is the nano-scale roughness super hydrophobic surface of " lotus leaf effect " for preparation, such as alumina formwork
Method, sol-gel method, chemical vapour deposition technique, electrochemical deposition method etc., but its application be still limited by complex process, cost high,
The problems such as light transmission difference and poor durability.
Therefore, invent and a kind of can form on vehicle glass surface that to have the low cost of excellent light transmittance and durability super-hydrophobic
Property film layer has important practical significance.
Summary of the invention
The present invention devises a kind of vehicle glass superhydrophobic films layer and preparation method thereof, and it be existing for it to solve the technical problem that
Super hydrophobic surface glass applications is had to be still limited by the problems such as complex process, cost height, light transmission difference and poor durability.
In order to solve the technical problem of above-mentioned existence, present invention employs below scheme:
The preparation method of a kind of vehicle glass superhydrophobic films layer, comprises the following steps: step 1, with organic solvent will etc.
Isotactic polypropylene dissolves, and obtains the solution A that polypropylene content is 0.05wt% ~ 5wt%, and step 2, preparation are containing SiO2The solution B of colloidal sol,
Step 3, then step 1 gained solution A is mixed according to the mass ratio of 1:1 ~ 10 with step 2 gained solution B, wherein SiO2Colloidal sol
Solid content is 0.96% ~ 2.05%, Nano-meter SiO_22Particle diameter is 35.6 ~ 205.1 nm, step 4, by step 3 gained polypropylene and SiO2
Hybrid sol solution is applied to form coating, after 150 ~ 600 DEG C of high-temperature process, with organic through the glass surface of activation processing
Siloxane solution coating is carried out surface modify i.e. can get water contact angle be not less than 150 °, slide angle be not higher than 5 ° durable,
The transparent superhydrophobic films layer with low cost.
Further, isotactic polypropylene granule or fiber are added in organic solvent A by step 1, heating magnetic agitation 1 ~
10 hours, obtain the solution A that polypropylene content is 0.05wt% ~ 5wt%；Wherein, heating temperature range is 60 ~ 180 DEG C, preferably
120~150℃；Magnetic agitation speed is 800 ~ 2400 revs/min, preferably 1000 ~ 1500 revs/min；Organic solvent A is decahydro
Change any one of naphthalene, tetrahydronaphthalene, isoamyl acetate, 1,2,4-tri-chlorination benzene, o-Dimethylbenzene, preferably dimethylbenzene, acetic acid
Isopentyl ester or tri-chlorination benzene solvent.
Further, in step 2, solution B preparation process is as follows: in 40 ~ 60 DEG C of water-baths, by presoma esters of silicon acis Si (OR)4
Add in organic solvent B, magnetic agitation 1 ~ 5 minute, it is slow added into ammonia, when adding while ammonia continuously stirred one section
Between obtain containing SiO2The solution B of colloidal sol；Wherein, presoma esters of silicon acis Si (OR)4In R group carbon atom number be 1 ~ 4, including
Tetramethoxy-silicane, tetraethoxysilane, propyl-triethoxysilicane, isobutyl triethoxy silane, isobutyl trimethoxy
In silane one or more, its addition accounts for the 3.3wt% ~ 7.1wt% of solution B total amount；Organic solvent B is the first in alcohols solvent
One or more in alcohol, ethanol, isopropanol, n-butyl alcohol, organic solvent B is the acetone in ketones solvent or butanone；Organic
Solvent B is the toluene in aromatic solvent or dimethylbenzene, one or both mixture in preferred alcohols kind solvent；Ammonia addition
Accounting for the 1.1wt% ~ 6.9wt% of solution B total amount, its addition rate controlled in 30 ~ 180 μ l/min, the total mixing time of whipping process is
1 ~ 3 hour.Above-mentioned ammonia addition rate controlled is at 30 ~ 180 μ l/min, and preferably ammonia adds speed is 60 ~ 100 μ l/min.
The total mixing time of above-mentioned whipping process is 1 ~ 3 hour, preferably 1 ~ 1.5 hour.
