Description
Technical field
The present invention relates to printing material technical fields, and in particular to a kind of raising Nano silver grain is in aqueous, environmental protective ink
The method of dispersiveness.
Background technology
Ink（Ink, printing ink）It is the important materials for printing, it is by printing or air brushing by pattern, text
Word shows on the substrate.Ink includes main component and auxiliary element, they equably mix and are formed through repeat-rolling
A kind of stickiness colloidal fluid.For various printings such as books and periodicals, packing and decorating, building decoration and electronic circuit plates.With society
Demand increases, ink kind and yield also respective extension and growth.The constituent of common ink mainly includes：Pigment, connection
Material, auxiliary agent mineral oil etc., wherein pigment include colored pigment and filler material.The fineness of ink is higher, and concentration is bigger, and printing comes out
Picture and text just become apparent from full, printing effect is preferable.Nanoparticle is added in ink, can not only improve the fineness of ink,
Also make ink that there are the specific functions such as anti-fake, conductive simultaneously.
The constituent of nano ink and common ink it is essentially identical, difference part is the size of pigment particle size,
The pigment particle size of nano ink is nanoscale, and the pigment particle size of common ink is only micron order, and the two size differs nearly 1000
Times.Molecule in nano ink has good wettability, these particles can not only improve the lipophile of ink, but also
It can guarantee the stability of ink.The particle shape of pigment is smaller, then will not block site, and it is also thinner thus to print off the pattern come
It is greasy, rich in full power.In addition, some nano inks also have in noctilucence ability and good covering.Conductive nano
Ink is the indispensable material of printed electronic device, and key position is occupied in the upstream of printed electronic industrial chain, is printed electronic production
The core technology of industry chain upstream.At present, nano conductive printing ink is mainly used in flexible transparent conductive film, RFID antenna, crystal
The making of the electronic devices such as pipe, paper battery.
Nano silver has good electric conductivity and inoxidizability, therefore, nano-Ag particles is added in printing ink to manufacture nanometer
Silver-colored electrically conductive ink becomes first choice prepared by electrically conductive ink.Nano silver conductive ink preparation method is generally divided into dispersed nano-silver particles
The preparation of liquid, the drying and concentration of dispersion liquid, add in needed for solvent and auxiliary agent disperseed again, receiving required by finally obtaining
The silver-colored electrically conductive ink of rice, still, nano particle has very high surface area, when the grain size of nano particle is in below 10nm, surface
The ratio of atom increases sharply, and when grain size is down to 1nm, surface atom ratio is up to more than 90%, and atom almost all focuses on
The surface of particle in advanced activation state, causes surface atom ligancy deficiency and high surface energy, so that these atom poles
It is easily combined and settles out with other atoms.In addition, nano-particle has very high surface/volume, solution is suspended in
In particle generally acted on be subject to Van der Waals force, therefore, the problem of Nano silver grain is easily reunited in ink, cause
It is scattered uneven, influence the quality of ink.
Chinese invention patent application number 201410075506.9 discloses a kind of Nano silver conductive ink and its preparation side
Method, Nano silver conductive ink include the nano silver of 79.3%-82.7%, graphene 0.001%-0.02%, phenolic resin 3%-7%,
Butyl acetate 10%-13%, stabilizer 1%-1.8%；The granularity of nano-Ag particles is 2-40nm；Stabilizer includes table
Face activating agent, dispersant, antioxidant and levelling agent.But nano-silver powder and graphene are all easily reunited in scheme, ink
Quality depends on the preparation of stabilizer.
Chinese invention patent application number 201010033973.7 discloses a kind of Nano silver conductive ink, by nano-silver powder,
Terpene alcohol compound solvent and auxiliary agent mixed preparing form electrically conductive ink.It is molten to prepare terpene alcohol compound used during electrically conductive ink
Agent can be uniformly dispersed nano-silver powder, and can keep prolonged stabilization.The terpene alcohol compound solvent can to lead
Electric ink keeps good with substrate and sprawls state.But terpene alcohol compound solvent has special odor and certain physiological activity,
It is unfavorable for long-term a large amount of uses.
Said program adds stabilizer from ink and selects that the compound solvent that disperses of nano-silver powder is suitble to is portable
High nano silver dispersiveness, although the ink prepared has an exploitativeness, the dispersities of nano silver particles to additive and
Compound solvent is more demanding, is unfavorable for the raising of ink comprehensive performance.
