Solvent composition for manufacturing laminated ceramic component

Abstract

The invention provides a solvent composition for manufacturing laminated ceramic components, wherein the adhesive property of ethyl cellulose and other adhesive resin can be fully exerted and high-precision fine patterns or films are generated with the proviso that the coating surface member is not eroded.The solvent composition is easy to be subject to evaporation and drying, thereby remarkably improving the production efficiency of laminated ceramic components.The solvent composition for manufacturing laminated ceramic components comprises at least one of the following components: alkylene glycol alkyl ether (end asynmmetric ether chain ), alkylene glycol alkyl ether (end asynmmetric ether chain ) and lactic acid alkyl ester dictyoprolene.

Description

technical field [0001] The present invention relates to a solvent composition for manufacturing a laminated ceramic part, the solvent composition is contained in a paste, and in a step of manufacturing a laminated ceramic part, by applying the paste to a surface to be coated Wiring or a coating film can be formed on the member (hereinafter also referred to as "coated surface member"). Background technique [0002] As laminated ceramic components, capacitors, inductors, varistors, thermistors, speakers, drivers, antennas, solid oxide fuel cells (SOFCs) and the like are known. These components are formed by laminating ceramic layers or thin layers consisting of ceramic layers and conductive layers. Capacitors, inductors, varistors, thermistors, speakers, drivers, and antennas are mainly formed by combining and laminating ceramic layers with conductive layers, while solid oxide fuel cells (SOFC) are mainly formed by laminating only multiple ceramic layers. get the parts.

Problems solved by technology

However, the following problems have been found: when the paste containing the solvent composition is coated and dried by heating under normal pressure, it is necessary to heat for a long time, but after heating for a long time, the polyvinyl acetal resin will be Softening and deformation of the laminated sheet of the binder resin

In addition, in recent years, there is a tendency to increase the number of laminated layers by reducing the thickness per layer in laminated ceramic parts, but it has also been pointed out that there is a problem that if the same drying process is applied to each layer as in the past, time, it will increase the time required to manufacture each laminated ceramic part, which will lead to lower production efficiency

Therefore, it is desired to provide a paste that can be evaporated in a short time under low-temperature drying conditions (for example, 40 to 100° C.) when the paste for forming wiring or a coating film is applied to the surface member to be coated without evaporating. However, for the solvent composition described in Patent Document 4, since it contains a large amount of triacetin that evaporates slowly under the above-mentioned low-temperature drying conditions, it is difficult to shorten the drying time under low-temperature conditions.
