Description
Technical field
The present invention relates to a kind of ink, relate more specifically to a kind of antenna for mobile phone electrically conductive ink.
Background technology
Electrically conductive ink, as the important materials of printed wiring, plays irreplaceable vital role in 3C Product printing.Such as, for conduction current during antenna for mobile phone received signal, get rid of the static charge of accumulation.But current electrically conductive ink exists under hot and humid condition, resistance is unstable.And conducting wire now along with printing is more and more thinner, resistance is also increasing, even there will be bonding force bad, broken string, with the problem such as the sticking power of base material cannot ensure.In addition, the stability in storage of more existing ink is poor, even will solidify within short-term, the phenomenon of layering.Thus, there is good performance and resistance-stable electrically conductive ink be people institute in the urgent need to.
Summary of the invention
For overcoming the problems referred to above of the prior art, the invention provides a kind of antenna for mobile phone electrically conductive ink, its electric conductivity is high, and resistance change is little under hot and humid condition.The not only environmental protection of this electrically conductive ink, but also there is excellent sticking power, endurance, stability in storage.
The technical solution used in the present invention is: a kind of antenna for mobile phone electrically conductive ink, and with the gross weight of electrically conductive ink for benchmark, its component primarily of following percentage composition forms:
Modified epoxy, 10 ~ 20%;
Silver powder, 50 ~ 70%;
Solvent, 10 ~ 30%;
Dispersion agent, 0.5 ~ 2%;
Defoamer, 0.5 ~ 2%;
Thixotropic agent, 0.5 ~ 1%;
Coupling agent, 2 ~ 5%.
Preferably, modified epoxy is the polyurethane-modified bisphenol A type epoxy resin of thermoplastic hydroxy.This kind of resin has had both the advantage of urethane resin and epoxy resin, has excellent cohesiveness, can effectively be combined by conducting particles.There is good chemically-resistant character, shrink lower during film-forming, reduce the fragility of coating simultaneously, enhance elasticity, shock-resistance.Enhance the bonding force of resin and base material with a small amount of hydroxyl in modified resin thus improve sticking power, the wettability of silver powder can be strengthened, promoting silver powder dispersion in the coating.
Preferably, silver powder is nano-scale silver powder, and the particle diameter of described silver powder is 15 ~ 30nm.Wherein not halogen-containing in this silver powder, the feature of environmental protection of energy guarantee system.
Further, solvent is one or both in ketone, esters solvent.Solvent evaporates speed should not too soon or too slow.If solvent evaporates speed is too fast, the viscosity of ink increases, and mobility is deteriorated, and impact is with the wetting of base material and adhere to, and application property also can be made to be deteriorated simultaneously.And if solvent evaporates is too slow, the thixotropy of ink is deteriorated, ink film sagging and thinning.So the present invention selects ketones solvent or esters solvent, or their mixing.
Further, ketones solvent is one or both in pimelinketone, your ketone of different fluorine.
Further, esters solvent is one or both in ethylene glycol ether acetate, 1-Methoxy-2-propyl acetate.
Certainly, antenna for mobile phone electrically conductive ink of the present invention is not limited to the kind of above-mentioned solvent, as long as the solvent of the electrically conductive ink character that can realize together with other components in ink desired by the present invention is all acceptables.
Preferably, dispersion agent is the silane alcohol base ammonium salt of the block interpolymers with acidic-group.Effectively can prevent pigment flocculation thus pigment form and aspect and tinting strength are settled out, reduce the loose colour in pigment composition and grow dim; The stability in storage of system increases; The wettability of pigment improves, and reduces the viscosity of abrasive.
Preferably, defoamer is Polyether Modified Polysiloxanes Defoaming Agent.This defoamer has certain levelling property while froth breaking, ensure that the smooth of system layer of ink.
Preferably, thixotropic agent is aerosil.This thixotropic agent can guarantee that system possesses excellent thixotropic property.When ink is static, viscosity is comparatively large, effectively can prevent the sedimentation of conducting particles; During construction printing, stirred, ink viscosity declines fast and can keep stable, ensure that construction printing.
Preferably, coupling agent is silane coupling agent.Serve as a connection between resin glue and conducting particles silver powder, effectively silver powder is evenly dispersed in resin, adds electroconductibility.
Each moiety of antenna for mobile phone electrically conductive ink of the present invention can directly be buied from commercial channels.
Compared with prior art, the present invention has following advantages: the invention provides a kind of antenna for mobile phone electrically conductive ink, it is by thermoplastic hydroxy's polyurethane modified epoxy resin, silver powder etc. become to be grouped into, and various composition cooperatively interacts, and makes ink have good sticking power, electrical property vary stable, 70 DEG C of temperature, under 90-95% humidity, resistance change rate is little.And ink has excellent stability in storage, place after 3 months in 50 DEG C of baking ovens, resistance change is little, without demixing phenomenon.Meanwhile, ink also has good application property.There is good application prospect.
