Its preparation method is: ethyl orthosilicate is added to the absolute ethyl alcohol of its total consumption half,Fully be mixed to get the first solution; Again ammoniacal liquor and second half absolute ethyl alcohol are fully mixed to get toTwo solution, slowly add the second solution in the first solution uniform stirring. sealing, room temperatureDisplay 5-8;
(3) prepare mixed sols liquid
Sol solutions A and sol solutions B are mixed by weight the ratio of 2:2, make colloidal sol mixedClose liquid, preparation method slowly drips sol solutions A in sol solutions B, after mixing, closeEnvelope, room temperature is displayed 10-25 hour.
The Best Times that described room temperature is displayed is 17 hours.
Applicant finds in preparation practice, the assembly time of mixed sols liquid and the increasing of makingThe light transmittance of permeable membrane has direct relation, for this reason, applicant's specialize mixed sols liquid notLight transmittance experiment under same assembly time, different optical bands. Experimental result is in table 1.
Light transmittance under the different assembly time of table 1 mixed sols liquid, different optical band
From table 1 can, in the time that mixed sols liquid is displayed 15-2O hour at ambient temperature,Its light transmittance at each wave band is higher, and while particularly displaying 17 hours, light transmittance reachesHigh value. For this reason, mixed sols liquid prepared by the present invention is all displayed 17 hours, to obtain maximumLight transmittance.
Beneficial effect of the present invention:
(1) it is high that the anti-reflection film of being prepared by mixed sols liquid of the present invention has light transmittance,Mechanical performance is strong, can be attached to preferably on solar energy vacuum tube outer tube wall.
(2) thin-film refractive index making is controlled between 1.20～1.35, after film, can makeCan make solar energy vacuum tube vestlet in 400-1000nm wave band mean transmissivity from 89.02%Bring up to 94.15%, amplification is 5.13%, and peak transmittance can reach more than 99%.
(3) found out the best assembly time of mixed sols liquid, to obtain maximum printing opacityRate, is convenient to batch production simultaneously and produces.
