Abstract

The invention discloses a preparation method for printing machine oil ink with improvable electrical conductivity. The preparation method comprises the following steps: firstly, adding modified epoxyresin into a reaction kettle; raising the temperature to 135 to 145 DEG C, and preserving heat for 35 to 45 minutes; then, adding propanediol butyl ether into the reaction kettle; continuing stirringfor 6 to 10 minutes, and then, adding glacial acetic acid to regulate the pH to 6.0; adding an adhesion promoter, increasing the stirring rotating speed to 115 to 125 r / min, wherein the stirring timeis 25 minutes; then cooling to a room temperature to obtain a mixture A. The invention aims to provide the printing machine oil ink with the improvable electrical conductivity. Compared with the priorart, the electrical conductivity of the prepared oil ink is greatly improved; the oil ink has high use value and a good application prospect.

Description

technical field [0001] The invention relates to the technical field of printing ink preparation, in particular to a preparation method of ink for printers whose electrical conductivity can be improved. Background technique [0002] Conductive ink is a paste ink made of conductive materials (gold, silver, copper and carbon) dispersed in a binder, commonly known as paste ink, which has a certain degree of conductivity and can be used for printing conductive points or conductive lines. Ink refers to the ink printed on conductive substrates to enable it to conduct current and eliminate the ability to accumulate static charges. It is generally printed on non-conductive substrates such as plastic, glass, ceramics or cardboard. The printing method is very wide, such as screen Printing, letterpress printing, flexographic printing, gravure printing and lithographic printing can all be used, and different printing methods can be selected according to the requirements of film thickness...
