PH is 10.5, is aged 20min；Add 12wt% sulphuric acid and adjust pH to 4.7, add hydroxy silicon oil 45 parts, after stirring 1h, be aged 1.5h
Rear filtration, filter cake, after sequentially passing through washing and washing with ethanol, is dried and to obtain white powder；2nd step, by weight, by anhydrous
Reactor put into by ethanol 30 parts, then drips silester 5 parts, after stirring, then drips ammonia, continues stirring 1 hour, then drips
Add 5wt% hydrochloric acid solution 5 parts, temperature rising reflux 2 hours；3rd step, add in the mixture that the 1st step obtains butyl titanate 3 parts, the
The white powder that 1 step obtains 10 parts and acetylacetone,2,4-pentanedione 2 parts, after stirring, add dehydrated alcohol 5 parts and 6wt% hydrochloric acid be molten
Liquid, stirs 30 minutes, sequentially adds DMF 3 parts and Polyethylene Glycol 12 parts, after stirring 40 minutes, is coated with
Material.
Beneficial effect
Printing opacity hydrophobic coating prepared by the present invention can be at the windshield such as automobile, aircraft, solar energy baffle plate, glass of building table
Face forms transparent hydrophobic coating, is provided simultaneously with preferable light transmission and hydrophobicity.
Detailed description of the invention
The preparation process of printing opacity hydrophobic coating:
1st kind:
1st step, by weight, adds 45 parts of sodium silicate, 6 parts of sodium sulfate and 466 parts of water in four-neck flask, stirs at 30 DEG C
Mixing 30min, be warming up to 85 DEG C, sulfuric acid solution to system pH of dropping 12wt% is 10.5, is aged 20min；Add 12wt% sulphuric acid to adjust
Whole pH to 4.7, adds hydroxy silicon oil 45 parts, after stirring 1h, filters after ageing 1.5h, and filter cake is washed through sequentially passing through washing and ethanol
Afterwards, white powder it is dried to obtain；
2nd step, by weight, puts into reactor by dehydrated alcohol 30～40 parts, then drips silester 5～7 parts, stirring
After Jun Yun, then drip ammonia, continue stirring 1 hour, then drip 5wt% hydrochloric acid solution 5～7 parts, temperature rising reflux 2 hours；
3rd step, adds butyl titanate 3～5 parts, white powder 10 parts that the 1st step obtains and second in the mixture that the 1st step obtains
2 parts of acyl acetone, after stirring, adds dehydrated alcohol 5 parts and 6wt% hydrochloric acid solution, stirs 30 minutes, sequentially add N,
Dinethylformamide 3 parts and Polyethylene Glycol 12 parts, after stirring 40 minutes, obtain coating.
2nd kind:
Difference with the 1st kind is: do not add hydroxy silicon oil to powder modification in the 1st step.
1st step, by weight, adds 45 parts of sodium silicate, 6 parts of sodium sulfate and 466 parts of water, at 30 DEG C in four-neck flask
Lower stirring 30min, is warming up to 85 DEG C, and sulfuric acid solution to system pH of dropping 12wt% is 10.5, is aged 20min；Add 12wt% sulfur
The sour pH to 4.7 that adjusts, filters after ageing 1.5h, and filter cake, after sequentially passing through washing and washing with ethanol, is dried and to obtain white powder；
2nd step, by weight, puts into dehydrated alcohol 30～40 parts reactor, then drips silester 5 parts, stir
After, then drip ammonia, and continue stirring 1 hour, then drip 5wt% hydrochloric acid solution 5 parts, temperature rising reflux 2 hours；
3rd step, adds white powder 10 parts and acetyl that butyl titanate 3 parts, the 1st step obtain in the mixture that the 1st step obtains
2 parts of acetone, after stirring, adds dehydrated alcohol 5 parts and 6wt% hydrochloric acid solution, stirs 30 minutes, sequentially add N, N-
Dimethylformamide 3 parts and Polyethylene Glycol 12 parts, after stirring 40 minutes, obtain coating.
The coating of gained, after still aging 24 hours, uses czochralski method film on K9 glass, and the rate of pulling is 10cm
Min, can use after dry.
Result of the test
As can be seen from the table, after being applied with the coating that the present invention provides, substrate still there is preferable light transmittance, especially
It is that silicon oxide powder has been carried out hydroxyl silicon oil modified by the 1st kind of coating, improves the light transmission of coating.Meanwhile, coating is also
Having preferable hydrophobicity, contact angle is less.
