Abstract

The invention discloses a photosensitive aluminium paste for plasma display site-selection electrodes. The aluminium paste includes the following components: by a weight ratio, 36-59 parts of aluminium powder, 2-20 parts of conductive oxygen-free ceramic powder, 2-7 parts of an inorganic binder, 12-28 parts of an organic carrier, 6-15 parts of a photopolymerization monomer, 3-8 parts of a photoinitiator, and 2-3 parts of an additive. The photosensitive aluminium paste of the invention is added with the conductive oxygen-free ceramic powder, reducing the amount of used aluminium powder and the cost.

Description

technical field [0001] The invention relates to a conductive coating composition and a preparation method thereof, in particular to a photosensitive conductive silver paste used for addressing electrodes of a plasma display and a preparation method thereof, belonging to the technical field of electronic materials. Background technique [0002] Conductive ink is an important electronic material, which is more and more widely used in membrane switch panels, keyboards, flexible conductive cables, electronic shielding, radio frequency identification (RFID) and other fields. [0003] Conductive inks usually consist of conductive fillers, organic polymer carriers, modifying additives and solvents. Among them, conductive fillers include carbon powder and metal powder, wherein carbon powder includes carbon black, graphite, etc., and the cost is low, but the conductivity is poor and the application range is small. Metal powders have good electrical conductivity, and the common ones ...
