Abstract

The invention provides a preparation method of a conductive pigment for art. The preparation method comprises the following steps: S1, preparing ultrafine conductive graphite; S2, preparing an ultrafine conductive graphite-nano silver material; S3, preparing coating modified graphite; S4, carrying out graft copolymerization of epoxy resin and conductive graphite; and S5, preparing the conductive pigment. The invention aims to provide an educational conductive pigment for children. When the water-based ink product is used, the water-based ink product only needs to be coated on the surface of abase material, a solid conductive connecting line can be formed after a solvent is evaporated, the connecting line is connected with a power supply, and a luminous body or other electric light sourcesor small toys are arranged at the joint of the two conductive connecting lines, so that the effects of serving as an electric lead, being convenient and safe and achieving educational entertainment are achieved.

Description

technical field [0001] The invention relates to the field of pigments, in particular to a preparation method and application of conductive pigments for art. Background technique [0002] Conductive ink is a paste pigment made by dispersing conductive materials (gold, silver, copper and carbon) in a binder. It has a certain degree of conductive properties and can be used for printing conductive points or conductive lines. Gold-based conductive inks, silver-based conductive inks, copper-based conductive inks, and carbon-based conductive inks have reached practical use. Conductive ink manufacturers are all used in printed circuits, electrodes, electroplating bottom layers, keyboard contacts, and printed resistors. However, this type of conductive ink is generally only used in industrial production. With the development of science and technology and the improvement of living standards, people's investment in children's education is also gradually increasing, and various educat...
