9. a kind of preparation method of the nano silver wire ink of silk-screen printing as described in claim any one of 1-8, its feature
It is, this method specifically includes following steps：
(1) aqueous solution of hydroxypropyl methyl cellulose is prepared first, takes 1~5 part of hydroxypropyl methyl cellulose to add 70 parts of temperature
For strong stirring half an hour in 80 DEG C of hot water, mixing speed preferably 600~900rpm；Then the water 24~29 of normal temperature is added
Part, stir 4 hours at room temperature, mixing speed preferably 300~600rpm, hydroxypropyl methyl cellulose is completely dissolved to obtain hydroxypropyl
Methyl cellulose cellulose content is 1~5wt% hydroxypropyl methyl cellulose aqueous solution；
(2) composition of the nano silver wire ink as described in claim any one of 1-8 weighs the water of corresponding weight in container, so
After add water-based polyimide resin, stir；Then sequentially added in the state of stirring quantitative polyacrylic resin,
Polyvinyl alcohol, aqueous pigment, auxiliary agent, it is stirred well to each component and is well mixed；
(3) in the state of stirring, the aqueous solution of quantitative hydroxypropyl methyl cellulose is added, is well mixed；Then silver is added
Nano wire, it is well mixed；Acid is eventually adding, is sufficiently stirred, finely dispersed nano silver wire ink is made.
