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, is being brought into play irreplaceable vital role in 3C Product printing.For example, conduction current during for antenna for mobile phone received signal, gets rid of the static charge accumulating.But current electrically conductive ink exists under hot and humid condition, and resistance is unstable.And now, along with the conducting wire of 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 guarantee.In addition, the stability in storage of more existing ink is poor, even within short-term, will solidify the phenomenon of layering.Thereby, there is good performance and resistance-stable electrically conductive ink and be people 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 take the gross weight of electrically conductive ink as benchmark, it is mainly made up of the component of following percentage composition:
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 thermoplasticity hydroxyl polyurethane modified bisphenol A type epoxy resin.This kind of resin had both the advantage of urethane resin and epoxy resin, has excellent cohesiveness, can effectively conducting particles be combined.There is good chemically-resistant character, when film-forming, shrink lowlyer, reduced the fragility of coating simultaneously, strengthened elasticity, shock-resistance.Thereby the bonding force that has strengthened resin and base material with a small amount of hydroxyl in modified resin has improved sticking power, can strengthen the wettability of silver powder, promote the dispersion of silver powder in 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 be too soon or is too slow.If solvent evaporates speed is too fast, the viscosity of ink increases, mobility variation, and impact soaks and adheres to base material, also can make application property variation simultaneously.And if solvent evaporates is too slow, the thixotropy variation of ink, ink film sagging and attenuation.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 of the present invention is not limited to the kind of above-mentioned solvent with electrically conductive ink, as long as can be all acceptables with the solvent of realizing the desired electrically conductive ink character of the present invention together with other components in ink.
Preferably, dispersion agent is the silane alcohol base ammonium salt with the block interpolymers of acidic-group.Thereby can effectively prevent that pigment flocculation from settle out pigment form and aspect and tinting strength, reduce the loose colour in pigment composition and grow dim; The stability in storage of system increases; The wettability of pigment improves, and has reduced the viscosity of abrasive.
Preferably, defoamer is Polyether Modified Polysiloxanes Defoaming Agent.This defoamer has certain levelling property in froth breaking, has guaranteed the smooth of system China ink layer.
Preferably, thixotropic agent is aerosil.This thixotropic agent can guarantee that system possesses excellent thixotropic property.When ink is static, viscosity is larger, can effectively prevent the sedimentation of conducting particles; When construction printing, stirred, ink viscosity fast-descending also can keep stable, has guaranteed construction printing.
Preferably, coupling agent is silane coupling agent.Between resin glue and conducting particles silver powder, serve as a connection, effectively silver powder is evenly dispersed in resin, increased electroconductibility.
Antenna for mobile phone of the present invention can directly be buied from commercial channels by each moiety of electrically conductive ink.
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 thermoplasticity hydroxyl polyurethane modified epoxy, the one-tenth such as silver powder are grouped into, and various compositions cooperatively interact, and make ink have good sticking power, electrical property vary stable, 70 ℃ of temperature, under 90-95% humidity, resistance change rate is little.And ink has excellent stability in storage, in 50 ℃ of baking ovens, to place after 3 months, resistance change is little, without demixing phenomenon.Meanwhile, ink also has good application property.There is good application prospect.
