Description
Technical field
The invention belongs to conductive ink field, be specifically related to a kind of silver-colored conductive ink of size uniform.
Background technology
In all metals, the conduction of silver and heat conductivility the best, therefore it is widely used in fields such as electronic information.In such applications, silver occurs with forms such as silver powder, silver nano-grain, nano silver wires.Wherein, the neutral gear between nano silver wire makes its consumption much smaller than other ag materials, and then can significantly reduce costs.Meanwhile, the neutral gear between nano silver wire also gives a lot of peculiar property of its film, as good light transmission.Therefore, it is considered to the ideal material that conducting wire builds, and is extensively studied.Such as, in patent CN103008679A, CN104650653A, CN103627255A and CN104464880A, people's nano silver wire and various auxiliary agent have been mixed with the silver-colored conductive ink of difference in functionality, and then prepared silver-colored conductive film with these inks, in a lot of, achieve application.
But different occasion needs the nano silver wire mating different size just can reach the requirement of low cost and high conduction performance.Such as, the nano silver wire for spraying touch-screen conductive film is distinguished, mostly at 10-20 μm to some extent according to the difference of shower nozzle; Nano silver wire for some fine-line (< 6 μm) then requires at 1-5 μm; Nano silver wire for blade coating then can reach 40 μm.But above-mentioned patent nano silver wire used then can not ensure size uniformity.Patent at present about silver nanoparticle ink size uniformity does not then have substantially.Meanwhile, in conventional silver-colored ink preparation process, the silver nano material that a lot of size departs from requirement is rejected, and this greatly adds silver-colored ink cost, is unfavorable for that it is applied.
Therefore, exploitation can be close to the homogeneous silver-colored conductive ink of the silver nano material that 100% utilizes reaction to produce is the problem that solution is needed in conductive ink field badly.
Summary of the invention
The object of the present invention is to provide a kind of silver-colored conductive ink of size uniform, solve the silver nano material waste problem in silver nano material yardstick heterogeneity in current ink and ink production process.In the ink of the present invention's exploitation, silver nano material yardstick is homogeneous.Meanwhile, the silver nano material that reaction produces is close to 100% utilization, greatly reduces the cost of ink.These make these inks can in electronic information field large-scale application.The feature of this ink is, its preparation process is:

(3) separation of ink inside relates to our homemade many sized nanostructures material separation returnable bottle.This bottle has large, medium and small three kinds of specifications, and total size of the appendage of its tank body and outside corresponds to the centrifugal bottle size of conventional large, medium and small whizzer.In often kind of returnable bottle, at the bottom of from bottleneck to bottle, have 7 metafiltration films.Filter sizes size is respectively 50 μm, 40 μm, 30 μm, 20 μm, 10 μm, 5 μm and 1 μm from top to bottom.Meanwhile, there is an osculum that can open and shut every metafiltration film position on the upper side a little, and is used for releasing ink;
(3) sepn process of ink inside is: joined by the ink that (2) obtain in Separation and Recovery bottle, centrifugal twice.Then Separation and Recovery bottle is carefully taken out, do not vibrate.From top to bottom, the ink of different layers is released respectively, obtain the conductive ink of size uniform;
(4) in, existing body deterministic process is: choose a small-sized centrifuge tube, weigh m
1.Then from certain ink, take out 2ml ink, weigh m
2.Then add alcohol dilution centrifugal, outwell upper solution, continue repetition twice.Then vacuum drying oven is put into dry 10 minutes.Take out and weigh m
