Cataplasm used for inner electrode and laminated ceramic electronic part using the same

Abstract

The invention relates to a cataplasm used for an inner electrode and a laminated ceramic electronic part using the same, and to be specific, relates to the cataplasm used for the inner electrode comprising dispersant having specific structure, and therefore the compatibility of the solvent is high, and the problem of the gelation phenomenon and the rising of the viscosity of the cataplasm can be solved. The thermal decomposition performance is good, and therefore the cataplasm used for the inner electrode does not generate crackles during the plastification, and in addition, the laminated ceramic electronic part using the cataplasm used for the inner electrode is provided.

Description

technical field [0001] The present invention relates to a paste for internal electrodes and a laminated ceramic electronic component (PASTE FOR INTERNAL ELECTRODE AND MULTI-LAYER CERAMIC CAPACITOR USING THE SAME) prepared using the paste for internal electrodes, and relates in more detail to the The agent contains a dispersant with a specific structure, so it has a high affinity for solvents, and can effectively solve the above-mentioned gelation phenomenon and viscosity increase of the paste for internal electrodes, and because it has good thermal decomposition, it does not occur during plasticization. A cracked paste for internal electrodes and a laminated ceramic electronic component including the paste for internal electrodes. Background technique [0002] A laminated ceramic capacitor as an example of a laminated ceramic electronic component has a structure in which a plurality of dielectric layers and internal electrode layers are alternately laminated. In producing t...

AI Technical Summary

Problems solved by technology

As a result, the gelation phenomenon of the internal electrode paste is caused, and the viscosity stability is reduced, resulting in a decrease in printability (thickness, resolution) at the same time.

[0006] In addition, the ultrafine particles of the above-mentioned electrode material powder and ceramic powder interact with the functional groups of the polymer to degrade the role played by multiple polymers in the adhesive force and adhesive force of the paste printing layer, which can cause lamination damage. Poor alignment, poor delamination, etc.

[0007] Therefore, in order to solve the above-mentioned problems, although a method of increasing the amount of binder in the paste has been developed, in this case, there is a decrease in the density of the printed film and an increase in the thickness of the printed film, resulting in a decrease in electrode connectivity after firing. The problem

In addition, there is a problem that cracks are generated due to the generation of a large amount of high-temperature gas during the plasticization and firing processes for removing high-molecular-weight binder organic matter.

[0008] As another solution, although a method of increasing the amount of dispersant has been developed, according to the type of dispersant used, the cohesive force and cohesive force of the printing film can be reduced. Like the adhesive, there is a large amount of The problem of organic matter, so it is particularly important to choose a suitable dispersant
