The present invention relates to a paste for internal electrodes and a laminated ceramic electronic component prepared therefrom. More specifically, the paste for internal electrodes contains a dispersant with a specific structure, so it has a high affinity for solvents and can effectively solve the problem. The gelling phenomenon and viscosity increase of the above-mentioned paste for internal electrodes, and the paste for internal electrodes that do not cause cracks during plasticization due to good thermal decomposition properties, and laminated ceramic electronics including the paste for internal electrodes part.

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 THESAME) prepared using the paste for internal electrodes, and relates in more detail to the above-mentioned paste for internal electrodes. Contains a dispersant with a specific structure, so it has high affinity for solvents, and can effectively solve the above-mentioned gelation phenomenon and viscosity increase of the paste for internal electrodes, and has good thermal decomposition property, so it does not cause cracks during plasticization A 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 alter...

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
