Abstract
The invention discloses a high-solid content jet-printing conductive ink. The high-solid content jet-printing conductive ink comprises, by mass, 20 to 70% of a solvent type silver complex solution, 10 to 40% of a nano-silver particle, 1 to 20% of a viscosity modifier, 0.1 to 5% of a surfactant and 0.5 to 10% of a water retaining agent. The high-solid content jet-printing conductive ink provided by the invention inherits advantages of solvent type conductive ink and granule type conductive ink, overcomes the problems of high solid content and great viscosity of traditional conductive ink, has high solid content while guaranteeing low viscosity, meets requirements of jet-printed circuits and has good dispersibility, high stability, low temperature sinterability and excellent conductivity after molding.
Description
Technical field
The present invention relates to electrically conductive ink, relate in particular solvent-particle compound-type conducting ink of high solids content, high conductivity, belong to printed electronic field.
Background technology
In electronic industry, the manufacture of conducting wire (circuit) is most important, and the various electric equipment productss such as computer, electronic tag, thin film switch, flexible display, solar cell, military weapons system all be unable to do without the manufacture of circuit.The technological process of welding, etching and silk-screen technology that tradition is manufactured circuit is loaded down with trivial details, consume energy high, cost is high, it is high to pollute, also limited to the selectivity of substrate, cannot meet gradually the needs of hyundai electronics industry.Spray printing circuit engineering is a noncontact, full addition, the direct imaging technique of material without the Digital Control of forme, in recent years, design simple and direct, with low cost with environmental protection, technique flexibly, the substrate of undertaking the printing of compatible strong, be applicable to the significant advantages such as multilayer manufacture and become the research and development focus in the fields such as electronics, material, biology.
The core of spray printing circuit engineering is shower nozzle technology and electrically conductive ink technology, and in various shower nozzle technology quite ripe today, the electrically conductive ink of exploitation high-quality becomes the key point of spray printing circuit engineering.Traditional spray printing electrically conductive ink is divided into solvent-borne type and nanoparticle form.In solvent-borne type electrically conductive ink, electro-conductive material is metal complex, and this electrically conductive ink viscosity is low but stability is not good enough; The electro-conductive material of granule type electrically conductive ink is metal nanoparticle, and nano particle has unique nanometer size effect, and sintering temperature is low, good dispersity, but along with the increase of the solid content of particle, the viscosity of ink also can increase, and easily stops up printing nozzle.Chinese patent CN102321402A discloses a kind of agranular type electrically conducting transparent ink and preparation method thereof, mainly formed by solvent organic amine or ammoniacal liquor and organic salt, when preparation, obtain with other solvent, in this conductive ink, the massfraction maximum of silver reaches 40% again.Chinese patent CN102766371A discloses a kind of preparation method of conductive ink, is made up of nano particle, solvent and the dispersion agent of nucleocapsid structure.Wherein the nano particle of nucleocapsid structure is by the complexes preparation of two or more different nano particles, and this electrically conductive ink cost is low, good stability, but metal solid content is less than 30%.Solid content is low, and print circuit thickness is just little, and circuit impedance is very large, does not reach electron trade and uses standard.
Therefore, the present invention is in conjunction with the advantage of solvent-borne type and granule type electrically conductive ink, the solvent-particle compound-type conducting ink that develop a kind of high solids content, low viscosity, low-temperature sintering, conducts electricity very well.
Summary of the invention
The object of the invention is to the defect existing for above-mentioned technology, the spray printing electrically conductive ink of a kind of low viscosity, high solids content, high conductivity is provided.Electrically conductive ink of the present invention is in conjunction with the advantage of solvent-borne type and granule type electrically conductive ink, and the solid content that has overcome the existence of conventional conductive ink is high, and the problem that viscosity is large has lower viscosity in ensureing higher solids content, meets spray printing circuit requirement; Electrically conductive ink good dispersity of the present invention, there is higher stability and low-temperature sintering performance.
The present invention is achieved through the following technical solutions: a kind of high solids content spray printing electrically conductive ink, it is characterized in that, and formed by following component and mass percent:
Solvent-borne type silver complex solution: 20～70%
Nano-Ag particles: 10～40%
Viscosity modifier: 1～20%
Tensio-active agent: 0.1～5%
Wetting Agent for Printing Inks: 0.5～10%
