Problems solved by technology

[0004] The preparation of metamaterials by printing has been partially disclosed. For example, patents with publication numbers CN106427115A and CN106220211A have prepared metamaterials by screen printing process, but the screen printing materials they use are all ruthenium dioxide-based glass powders. The cost of ruthenium is extremely high, the particles are large, and the processing accuracy is poor; the patent with the publication number CN102718576A prepared a metamaterial resistive surface by screen printing a mixture of strontium lanthanum manganate powder and organic solvent, but its resistance is relatively high And it is not easy to control, the organic solvent used in the preparation process is cracked under high temperature conditions, which affects the performance

Abstract

The invention discloses a high-temperature-resistant printing material which is prepared by mixing 10 to 15 mass parts of an inorganic bonding material and 0.5 to 6 mass parts of a conductive material, wherein the inorganic bonding material is one or a mixture of water glass, silica sol, alumina sol, aluminum silicate or aluminium dihydrogen phosphate; the conductive material is one or a mixture of graphite powder, graphene, a carbon nano tube, carbon black, titanium nitride powder or ruthenium dioxide powder. The high-temperature-resistant printing material disclosed by the invention can be applied to a high-temperature condition of 700 DEG C or higher; after being subjected to high-temperature thermal treatment of the inorganic bonding material, an oxide film can be formed on the surface of the conductive material to prevent oxidization of the conductive material; meanwhile, the high-temperature-resistant printing material further has the advantages of small thermal expansion coefficient, high heat stability and high thermal matching performance with a ceramic substrate.

Description

technical field [0001] The invention relates to a high-temperature-resistant printing material, and also relates to the application of the above-mentioned high-temperature-resistant printing material, which belongs to the technical field of printing materials. technical background [0002] Since the invention of woodblock movable type printing technology in China, the printing methods have changed with each passing day and are all-encompassing. The most commonly used industrial printing methods today are: offset printing, flexographic printing and screen printing. In the traditional printing process, ink is widely used as printing materials due to its good adhesion and uniformity. Traditional organic solvent-based inks consist of organic solvents, pigments, organic binders, fillers and auxiliary agents. [0003] With the cross-infiltration of printing technology and other industry technologies, the development of ink functionalization has been promoted to meet the applicat...
