[Technical Field] The present invention relates to a solvent composition for manufacturing a laminated ceramic part, which is capable of sufficiently exerting an adhesive property of an adhesive resin such as ethyl cellulose in a laminate In the manufacturing process of ceramic parts, it is difficult to cause the phenomenon of sheet immersion and it is easy to evaporate and dry, and it is superior to the coated sheet. [Prior Art] Among laminated ceramic parts, there are capacitors, inductors, varistors, thermal resistors, speakers, actuators, antennas, solid oxide fuel cells (SOFC), etc. 'by making a thin layer of a ceramic layer or a conductor layer Capacitors, inductors, varistors, thermistors, speakers, actuators, and antennas are mainly composed of laminated ceramic layers and conductor layers, and solid oxide fuel cells (SOFC) are laminated with a plurality of ceramic layers. Mainly. The layering method can also be carried out by repeatedly coating and baking a new layer on the calcined layer. Generally, in consideration of productivity and cost, in the state before calcination, multilayer lamination is carried out simultaneously. The laminating method of performing the method of performing the calcination at the same time as the calcination method is to form a laminate by repeatedly applying and drying a liquid which has been incorporated into each layer composition, and further superimposing and pressure-bonding the parts by the parts. And the method of high-layering. An example of a method for producing a laminated ceramic component is a method of producing a laminated capacitor. In general, it is produced by the following steps: 1: using a polyvinyl acetal resin such as polyvinyl butyral or an adhesive resin such as acrylic acid 201245132 or the like, and dispersing the ceramic powder to form a paste, thereby forming a paste. After the sheet is obtained, a soft sheet is obtained. 2: A conductor paste containing a conductive metal material such as nickel or palladium, or an organic solvent such as ethyl cellulose or sinyl alcohol as a main component is applied onto a soft sheet by a screen printing method or the like to form a wiring/coating film. 3: Drying the organic solvent in the above conductor paste. 4: The laminated sheet in which the wiring/coating film has been formed is cut into a predetermined size, and a plurality of sheets are laminated and heated and pressure-bonded to form a laminated body. 5: An electrode or the like is mounted on the laminate, and when it is calcined at a high temperature, a build-up capacitor can be obtained. In the above step, when the conductor paste is applied to the soft sheet, there is a case where the organic solvent in the conductor paste dissolves the adhesive resin contained in the soft sheet. This phenomenon is called a sheet etch phenomenon. The chip etching phenomenon is caused by the occurrence of voids or wrinkles in the ceramic layer of the multilayer ceramic capacitor, which is caused by poor wiring or coating film formation or short circuit. Such a problem occurs in a laminated ceramic part that utilizes the same lamination method. Conventionally, the thickness of each layer of the film is not so large, but in recent years, as the high-performance and miniaturization of the laminated ceramic parts, thin layers of the conductive layer and the ceramic layer constituting the device are being sought. The result 'has made the film dip phenomenon significantly disillusioned. Therefore, as an improvement method of the sheet etching phenomenon, improvements in various organic solvents used for coating paste have been examined. For example, in Patent Documents i and 2, it has been disclosed that a terpineol hydride or a terpineol hydride acetate is used as an organic solvent. However, there are 2 201245132 isomers in the terpineol hydride, and it is a raw material. « „ « α ^ „ Fresh mat is a natural product, because it is CX-L alcohol, β-terpineol and antimony ^ In the case of the mixing ratio or the purity of the right side, the phenomenon is caused by the origin of the product. Further, in the patent literature, a solvent such as hexanoic acid hexahydrate has been disclosed. However, since ethyl hexanoic acid and ethyl bromide (IV) increase the solubility to the coated and C-coated resin as the temperature rises in the drying step, there is a problem that the positive film cannot be effectively prevented. Ϊ Ϊ Ϊ 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 献 已 已 已 已 已 已 已 已 已 已 已 已 已 已 已 已 已 已 已 作为 已 作为 作为 作为 作为 作为The upper limit (four) point of the triacetate (tetra) m is soluble; the tablet etching resistance is improved by using a solvent composition which is low in a specific ratio and is mixed. However, the coating paste containing the solvent composition was subjected to "normal pressure heating under a dry shape". It was confirmed that the coated sheet having polyethylene as the adhesive resin was softened and deformed by heating for a long period of time. The right side is mixed with triacetin in a specific ratio, and the other agent is used to display the solubility of ethyl cellulose, so that the adhesive properties of 2: cellulose can be fully exerted, and at the same time, The ethylene acetal resin showed insolubility. Also, it was found that by balancing the excellent solubility for both the base cellulose and the polyvinyl acetal resin, it is possible to prevent the deformation of the coated sheet by recognizing the time required for evaporative drying, and also Preventing the phenomenon of sheet etch. "However, this = 201245132 is not sufficient for the adhesion of the coated solvent to the coated sheet by a /, eight specific solvents. Further, in Patent Document 5, a polyvinyl acetal resin (trade name "S_LEK BL_S", manufactured by Sekisui Chemicals Co., Ltd.) having a low molecular weight and a low polarity is produced, and a polymerization degree of 360, butyral is disclosed. Degree of chemical conversion: 74% by mole: Hydroxy f amount: 22% by mole] Polyvinyl acetal resin which is blended in a conductor paste and has a high molecular weight (trade name r s_leK ΒΜ·2) Sekisui Chemical Industry Co., Ltd. The degree of polymerization 850, the degree of butyralization of 68 mol%, the basis weight of 3 1 mol%, and the adhesion of coated #, in the examples, n-octanol was used in the conductive paste. However, in the case of n-octanol, there is a solubility in the high molecular weight polyvinyl butyral resin used for the soft sheet, and the sheet etch resistance is insufficient. It is difficult to control the solubility due to the dissolution of the low molecular weight, low polarity polyvinyl acetal resin and the dissolution of the solvent of the high molecular weight, high polarity polyvinyl acetal resin having the same polarity.
