Abstract

The invention discloses a screen printing conductive printing ink composition which comprises the following components in percentage by mass: 20-70 percent of conductive material powder, 1-20 percent of epoxy resin, 0.2-15 percent of epoxy resin latent curing agent, 1-30 percent of thermoplastic resin, 5-60 percent of organic solvent and 0-5 percent of epoxy resin flexibilizer. The preparation method comprises the following steps: mixing the thermoplastic resin powder and the organic solvent, mixing the epoxy resin, the epoxy resin flexibilizer and the epoxy resin latent curing agent to obtain a thermoplastic resin system, adding the conductive material powder to the thermoplastic resin system, mixing the conductive material powder with the thermoplastic resin system; and finally, adding the organic solvent to regulate the viscosity, thus obtaining the screen printing conductive printing ink composition. The product has the advantages of high mechanical strength, stable electrical properties, excellent chemical resistance, high base material adhesion force, low volatile organic compound (VOC) content and the like.

Description

technical field [0001] The invention relates to a printing ink composition and a preparation method thereof, in particular to a conductive ink composition and a preparation method thereof. Background technique [0002] Conductive ink is a special ink with a certain degree of conductivity. It is a conductive composite material formed by dispersing conductive particles (silver, copper, carbon) in the connecting material. After printing on the substrate, it acts as a wire, antenna, etc. role. [0003] In general, conductive ink should have good bending resistance, and the conductive lines printed on flexible substrates (PET and other plastic films) should not be broken at the bend or have a large change in resistance; in addition, conductive ink It should have a wide range of adaptability to various substrates and have strong adhesion to the substrate; the lower the resistivity of the conductive ink itself, the better, which is conducive to reducing costs; because some plastic...
