High-conductivity writing type conductive gel pen ink

Abstract

The invention provides a high-conductivity writing type conductive gel pen ink. The high-conductivity writing type conductive gel pen ink is composed of the following components by mass: 1 to 2 partsof formamide, 1 to 2 parts of ethanolamine, 4 to 16 parts of acrylic resin, 1 to 7 parts of conductive carbon black, 3 to 10 parts of graphite, 1 to 10 parts of a dispersant, 10 to 60 parts of water,1 to 3 parts of an antifoaming agent, 0.1 to 0.8 part of xanthan gum, 10 to 20 parts of propylene glycol methyl ether and 10 to 50 parts of carbon nanotube with a solid content of 5 parts. The high-conductivity writing type conductive gel pen ink provided by the invention has the advantages of low cost, strong adhesion force, excellent electrical conductivity, rapid forming at a normal temperature, smoothness in writing, insusceptibility to pen plugging and easy storage trough organic combination of the above-mentioned components, is specifically applicable to application in writing by being perfused into a conventional gel pen, and meets the increasing demands of the market.

Description

technical field [0001] The invention relates to a high-conductivity writing water-based conductive ink, which belongs to the technical field of water-based ink compositions. Background technique [0002] Printed electronics is one of the fastest growing technologies in the world today. Specifically, this technology is a method of manufacturing electronic devices on various substrates using traditional printing processes. The printing process generally only requires the use of ordinary printing equipment that can print patterns on the surface of materials. These printing equipment can realize, for example, screen printing. Printing, flexographic printing, gravure printing, offset printing or inkjet printing and other processes. The coordinated development of printing process and ink materials is the core research work in this field. Conductive inks have so far been deposited mainly by methods such as screen printing, sputter coating, inkjet printing, and airbrush spraying. ...

Problems solved by technology

Third, most of these inks contain nanoparticles, and nanoparticles require a high curing temperature, and the particle-type conductive ink may agglomerate and block the nozzle, which largely limits the product and reduces the large-scale availability of

This kind of conductive ink can achieve normal temperature brush writing condensation, but due to the high viscosity of the conductive ink body, long drying time, and high hardness, it needs to be written with a specially designed conductive pen tube and nib, and cannot be used in common gel pens. The production cost is greatly increased, which is not conducive to popularization and use
