Abstract

The invention relates to anti-Ag diffusion phototonus electro-conductive slurry and a preparation method thereof. The anti-Ag diffusion phototonus electro-conductive slurry contains the following ingredients (based on weight percentage): 50-80%of Ag power, 2-20%of function metal powder, 2-15%of adhesion promoter and 16-30%of photosensitive organic system. The function metal powder is the powder of zincum, stannum, bismuth or plumbum or the mixture of two or more of above metals. The photosensitive organic system contains photopolymerization initiator monomer, active thinner, preformed polymer and inert solvent. The conditions for the preparation method are easy to reach and the invention can effectively prevent the Ag from diffusing into the transparent medium layer if the phototonus electro-conductive slurry is used to prepare a BUS conductive electrode and an ADD conductive electrode for a plasma display, thus avoiding the phenomenon that the transparent medium layer turns yellow and remarkably improving the image display quality of the plasma display.

Description

technical field [0001] The invention belongs to the technical field of gas discharge, and relates to a photosensitive conductive paste, in particular to an anti-Ag diffusion photosensitive conductive paste and a preparation method thereof. Background technique [0002] A plasma display panel is a self-emissive flat panel display that has excellent characteristics such as light weight, small size, wide viewing angle, and fast response. The plasma display panel has a front glass substrate and a rear glass substrate, wherein a BUS electrode, a transparent dielectric layer and a MgO layer are prepared on the front glass substrate; ADD electrodes, a backplane dielectric layer, a barrier structure and a phosphor coating are prepared on the rear glass substrate layer. The BUS electrode on the front glass substrate of the plasma display panel and the ADD electrode on the rear glass substrate form a PDP three-electrode surface discharge structure. [0003] After preparing BUS elect...
