Abstract
The present invention discloses a kind of touch-screen slurry of suitable low temperature flash baking curing process, and it is by nano-silver powder and dendritic micron silver powder hybrid conductive silver powder, organic carrier and inorganic additive, accelerator composition.This touch-screen silver paste has excellent printing performance, meets low temperature drying curing process, with preferable line resistance after solidification, hundred lattice hardness tests, anti-hand scraping ability, the performance such as excellent contact resistance.
Description
Technical field
Produced the present invention relates to the electrocondution slurry that touch-screen is used, more particularly to low temperature flash baking curing process
The making of touch-screen silver paste.
Background technology
With the development of touch screen technology, touch-screen production production man produces the touch-screen of one of raw material to touch-screen
Electrocondution slurry requires also more and more higher, wherein house is much produced in order to save energy consumption, while improving production efficiency,
Touch-screen slurry is claimed in the requirement of 100 degree or so flash baking solidifications, and on the market now absolutely mostly
The touch-screen silver paste of number excellent performance is required for carrying out prolonged baking and curing using more than 130 degree of high temperature
Technique.
This patent, which is provided, has invented a kind of touch-screen silver paste of suitable low temperature flash baking curing process, solves above-mentioned
Nano-silver powder is added in problem, slurry can effectively reduce bulk resistor and contact resistance, while can increase touch-screen
The adhesive force of silver paste and base material, nano silver particles initially enter silver paste and base material in touch-screen silver paste drying course
Combination interface, its diffusivity is better than the Argent grain in other touch-screen silver pastes, generates part nano-particle
Caused by tunnel-effect.
Also there is very excellent performance after low temperature flash baking solidification, industry can be met in low temperature flash baking
The requirement of aspect, the blank filled up in industry.
