Abstract
The invention discloses ultraviolet curing conductive silver paste which is composed of organic silver halide, spherical silver powder, hyperbranched polyurethane acrylate, a photoinitiator, a photopolymerization monomer, an organic solvent and an auxiliary agent. The conductive paste added with the organic silver halide can generate a decomposition reaction under the irradiation of ultraviolet light to generate nano-particle simple substance silver which can be filled among micron-sized silver powder, so that the compactness and the uniformity of a film layer are improved, and the content of solid silver powder is reduced due to the introduction of the organic silver, so that the conductive paste is suitable for film printing. The invention also purposefully selects the polyurethane acrylate with a hyperbranched structure, improves the thixotropy of the paste, meets the requirement of high-precision screen printing, simultaneously uses the polyurethane acrylate as the connecting material resin of the silver paste, not only has the characteristics of good solubility, strong adhesive force, good glossiness and the like of polyurethane, but also has the characteristics of high mechanical strength, good water resistance and the like of the polyacrylate, and greatly improves the comprehensive performance of the UV silver paste.
Description
Technical field: the present invention relates to a kind of organic silver complexes ultraviolet light curing conductive slurries and preparation method thereof.
Background technique:
There are many conductive silver paste type, can be divided into room temperature curing conductive paste, intermediate temperature setting conductive paste, height again according to curing system
Temperature sintering conductive paste, ultraviolet light solidification conductive paste etc..Room temperature curing conductive paste is more unstable, and volume resistivity holds when room temperature storage
Easily change;High temperature silver paste sintering temperature is high, to semiconductor, sensing element and the not substrate of resistant against high temperatures such as flexible base board
Deng not applicable, narrow application range, and process cycle is long, and energy consumption is high;What domestic and international application was more at present is intermediate temperature setting conduction
Silver paste, solidification temperature is moderate, matches with the temperature resistant capability of electronic component and using temperature, and mechanical property is also more excellent,
But heat-sensitive element and flexible parent metal are still limited by.
UV photocuring principle refers to that under the irradiation of ultraviolet light photoinitiator absorbs the photon of specific wavelength, is energized into sharp
Hair-like state, forming free radical or cation then by the transmitting of intermolecular energy makes polymerizing prepolymer and photo-sensitive monomer
Etc. becoming excitation state, charge-transfer complexation body is generated, the continuous cross-linked polymeric of these combinations generates solidification in the extremely short time
At the high molecular polymer of tridimensional network.UV-Curing Electric Conductive Adhesives combine UV-curing technology and electrocondution slurry
Come, imparts the new performance of electrocondution slurry and expand application range, but since traditional solid silver powder is commonly available to thickness
Film printing is difficult to reduce printing film thickness, therefore the present invention uses organic halogenation silver and overspends the combination of urethane acrylate, can
To realize ultraviolet rapid curing and effectively improve the electric conductivity of slurry, which can be printed on electricity by way of printing
Sub- wiring board, thin film switch, radio frequency intelligent label (RFID), flexible coil, wearable product, thin film solar electricity
