In the course of the preparation of silver nanoparticles, explores the reaction temperature, reaction time on product performance. The results show that,the hydrazine hydrate can be successfully prepared by the excellent performance of nanoscale silver nanoparticles as a reducing agent by chemical reduction. This article also prepared to test the nano silver particles as a conductive filler, urethane resin and acrylic resin as binder, with ethanol and ethyl acetate as the solvent, and adding other additives (defoamers, coupling agents, etc.) Preparation of a conductive ink. The prepared conductive ink applied to the glass sheet and then placed in the oven at different temperatures, it is determined that the preparation of conductive ink curing oven temperature of 100 ℃ stored in 40min, and finally cured after the ink was characterized This paper uses cross hatch a
