Abstract
The invention relates to metal oxide conducting ink and a preparation method thereof. The metal oxide conducting ink is characterized by mainly consisting of acrylic resin, chlorinated rubber fluid, Sb/SnO2 coated putty powder, a mixed solvent, aerosol and the like. The metal oxide conducting ink has the characteristics of high melting point, strong anti-oxidation ability, moderate cost, excellent conducting property, small electrical resistivity, good paint film layer toughness, high shock resistance and the like.
Description
Technical field
The present invention relates to a kind of metal conductive oxide printing ink and preparation method thereof, belong to the electrically conductive ink field.
Background technology
Along with developing rapidly and the flat raising of life running water of electronic industry, electrically conductive ink can be given performances such as it is antistatic, electromagnetic shielding as a kind of functional material in the industry such as electronics, machinery, light industry, metallurgy, has caused people's extensive concern.At present, the conductive powder material in the electrically conductive ink of using always mainly is that metal is that powder body material, carbon are powder body material and metal conductive oxide powder body material.Though metal powder material electroconductibility is stronger, their exist and to cost an arm and a leg, and be prone to the shortcoming of oxidation, corrosion-resistant, and metallic conduction powder density of material are big, are prone to the deposition caking thereby dispersed bad in matrix.Though carbon series conductive powder body material electroconductibility and stability are better, more difficult homodisperse, high-temperature oxidation resistance are not strong, and especially goods are prone to blackening and are not accepted.The metal conductive oxide powder body material is strong, moderate and receive publicity with its HMP, resistance of oxidation.
The present invention adopts Sb/SnO
2The coating putty powder is as conductive powder material; Overcome and solved metal powder material and carbon is existing deficiency of powder body material and defective; Provide a kind of and have the fusing point height, stronger, the moderate conductivity of resistance of oxidation is good; Resistivity is little, paint film layer good toughness, the metal conductive oxide printing ink of characteristics such as shock-resistance height.
Summary of the invention
To the effect that of the present invention: this metal conductive oxide printing ink is mainly by vinyl resin, chlorinated rubber liquid, Sb/SnO
2Compositions such as coating putty powder, mixed solvent, aerosil.
By being: vinyl resin 25～35% with mass percent; Chlorinated rubber liquid 10～20%; Sb/SnO
2Coating putty powder 25～35%; Mixed solvent 15～25%; Aerosil 2.0～8.0% is formed.
Its mixed solvent is: phenylcarbinol: diacetone alcohol: toluene: pimelinketone=15: 10: 7: 10.
Its Sb/SnO
2The preparation method of coating putty powder is: SnCl
4.0.5H
2O and SbCl
5Be dissolved in the deionized water respectively; Then two solution are mixed and heating, the NaOH solution 15% slowly adds in the mixed solution and keeps the final pH value of solution is 2, stops heating then; Do not stop to stir cooling 3h, white precipitate through filtration and with behind the deionized water wash more than vacuum-drying 3h.Dried presoma just becomes the conductive nano granules of stannic oxide that particle diameter is 10～15nm after the roasting in air.
The preparation method of its electrically conductive ink is: each material beyond the aerosil is stirred under impeller (pre-dispersed), and slurry is ground to fineness≤20 μ m through sand mill, gets final product in the package encapsulation container of packing into after the assay was approved.
The practical implementation method
1, Sb/SnO
