Description

  The present invention includes a paste capable of forming a wiring or a coating film by applying to a member having a surface to be coated (hereinafter sometimes referred to as a “surface member to be coated”) in a multilayer ceramic component manufacturing process. The present invention relates to a laminated ceramic component manufacturing solvent or solvent composition.

  Multilayer ceramic parts include capacitors, inductors, varistors, thermistors, speakers, actuators, antennas, solid oxide fuel cells (SOFC), etc., and parts are created by superposing thin ceramic layers and conductive layers. Capacitors, inductors, varistors, thermistors, speakers, actuators, and antennas are mainly laminated with a ceramic layer and a conductor layer, and solid oxide fuel cells (SOFC) are mainly laminated with a plurality of ceramic layers.

  As a lamination method, it is possible to apply a new layer on the fired layer and repeat the firing, but considering the productivity and cost, it can be fired at the same time after multiple layers are laminated before firing. It is common.

  In the method of laminating by simultaneous firing, the liquid containing the composition for forming each layer is repeatedly applied and dried to form a laminated sheet, and depending on the part, the obtained sheets are stacked and pressed to increase the number of layers. Use the method to do.

A method for manufacturing a multilayer capacitor will be described as an example of a method for manufacturing a multilayer ceramic component. Generally, it is manufactured through the following steps.
1: Ceramic powder is dispersed in a polyvinyl acetal resin such as polyvinyl butyral or a binder resin such as an acrylic resin and a solvent to form a slurry, which is formed into a sheet to obtain a green sheet.
2: Conductive metal material such as nickel and palladium, conductive paste mainly composed of an organic solvent such as ethyl cellulose and terpineol is applied on a green sheet by a printing method or the like to form a wiring / coating film.
3: The organic solvent in the conductor paste is dried.
4: The laminated sheet on which the wiring / coating film is formed is cut into a predetermined size, and a plurality of sheets are stacked and thermocompression bonded to obtain a laminated body.
5: An electrode or the like is attached to the multilayer body and fired at a high temperature to obtain a multilayer capacitor.

  In the above process, when the conductor paste is applied on the green sheet, a phenomenon may occur in which the organic solvent in the conductor paste dissolves the binder resin that forms the green sheet. This phenomenon is called a sheet attack phenomenon. The sheet attack phenomenon causes holes and wrinkles in the ceramic layer of the multilayer ceramic capacitor, and causes a decrease in yield due to poor wiring / coating film formation or a short circuit.

  Such a problem occurs in a multilayer ceramic component using a similar lamination method. In the past, the effect of the thickness of each layer was not so great, but in recent years, with higher performance and smaller size of multilayer ceramic parts, the conductor layers and ceramic layers constituting the device have been required to be thinner. Yes. As a result, the sheet attack phenomenon is noticeable.

  Accordingly, various methods for improving the organic solvent used in the conductor paste have been studied as methods for improving the sheet attack phenomenon. For example, Patent Documents 1 and 2 disclose that terpineol hydrogenated product, terpineol acetate or terpineol hydrogenated acetate is used as the organic solvent. However, it is difficult to completely prevent the sheet attack phenomenon only by using the above organic solvent, and it is necessary to select and use a polyvinyl acetal resin having a low degree of acetalization as a binder resin for forming a green sheet. was there. In addition, as a binder resin contained in the conductor paste, ethyl cellulose has a low solubility in the organic solvent, so that there is a problem in that it tends to cause defects during printing due to a change in viscosity of the coating paste over time.

  Patent Document 3 discloses that a solvent such as ethyl hexanoate or 2-ethylhexyl acetate is used as the organic solvent used in the conductor paste. However, these solvents have a problem in that the sheet attack phenomenon cannot be effectively prevented because the solubility of the binder resin contained in the green sheet is increased by the temperature increase in the drying process.

  In Patent Document 4, as an organic solvent used for the conductive paste, polyvinyl acetal resin (for example, polyvinyl butyral), acrylic resin, and ethyl cellulose show insolubility, and the boiling point is close to the upper limit of the temperature range that can be used in the manufacturing process. Disclosed is an invention for improving sheet attack resistance by using a solvent composition based on triacetin (boiling point: 260 ° C.) having a low-boiling organic solvent in which ethyl cellulose is soluble and added at a specific ratio. Has been. However, when the conductive paste containing the solvent composition is applied and then dried by heating at normal pressure, the content of triacetin having a low evaporation rate is large, so a long heating time is required. It was recognized that the green sheet using the binder resin was softened and deformed.

  Further, in recent years, the thickness per layer of the multilayer ceramic component tends to decrease and the number of layers increases, and if the same drying time is applied to each layer, the manufacturing time per multilayer ceramic component increases. The problem that production efficiency falls is also pointed out. Therefore, there is a demand for a solvent that evaporates in a short time under low temperature drying conditions (for example, 40 to 100 ° C.) without evaporating at the time of applying the paste. It was difficult to shorten.

  On the other hand, as a method of applying a conductor paste on a green sheet to form a wiring / coating film, for example, it is generally performed by a printing method such as a gravure printing method or a screen printing method. However, if the initial shear viscosity of the conductor paste is too low, it becomes difficult to form a fine wiring pattern. Therefore, the conductor paste is required to have a certain initial shear viscosity. As a method for increasing the initial shear viscosity, there is a method for increasing the amount of the binder resin added. In this case, there is a problem in that the residue of the binder resin generated at the time of firing increases to cause a decrease in conductivity.

Japanese Patent Laid-Open No. 07-240340 Japanese Patent No. 07-021833 JP-A-2005-116504 JP 2009-147202 A

  Accordingly, an object of the present invention is to provide a solvent or a solvent contained in a paste (hereinafter sometimes referred to as “coating paste”) for forming a wiring or a coating film by applying it to a surface member to be coated in a multilayer ceramic component manufacturing process. A binder composition that is excellent in solubility of the binder resin contained in the paste, can impart an initial shear viscosity suitable for a printing method to the paste, and forms a coated surface member. An object of the present invention is to provide a solvent or a solvent composition for producing a multilayer ceramic component that does not dissolve, that is, does not cause a sheet attack phenomenon, and can be quickly dried under low temperature drying conditions.

  As a result of intensive studies to solve the above problems, the present inventors have found that alkylene glycol dialkyl ethers and dialkylene glycol dialkyl ethers having at least one branched alkyl group at the end have a solubility in a binder resin such as ethyl cellulose. Polyvinyl acetal resin having a high degree of acetalization is insoluble, that is, it has an excellent balance of solubility in ethyl cellulose and polyvinyl acetal resin, and its boiling point is not so high. Solvent or solvent composition for producing multilayer ceramic parts containing dialkyl ether and / or dialkylene glycol dialkyl ether is excellent in solubility of binder resin contained in coating paste, and sheet attack phenomenon The initial shear viscosity of the coating paste can be easily adjusted to be suitable for each printing method without increasing the binder resin, and can be quickly dried even under low temperature drying conditions. I found. The present invention has been completed based on these findings.

（式中、Ｒ¹、Ｒ²は、同一又は異なって、直鎖状又は分岐鎖状アルキル基を示し、Ｒ¹、Ｒ²のうち少なくとも一方は分岐鎖状アルキル基である。Ａはアルキレン基を示す。ｎは１又は２である）
で表される化合物を含有する積層セラミック部品製造用溶剤又は溶剤組成物を提供する。 That is, the present invention provides the following formula (1):

(Wherein R ¹ and R ² are the same or different and represent a linear or branched alkyl group, and at least one of R ¹ and R ² is a branched alkyl group. A is an alkylene group. N is 1 or 2)
A solvent or a solvent composition for producing a multilayer ceramic component containing a compound represented by the formula:

  The solvent or solvent composition for producing a laminated ceramic component preferably contains at least dipropylene glycol methyl isobutyl ether or dipropylene glycol methyl isopentyl ether.

  As the multilayer ceramic component, a multilayer ceramic capacitor is preferable.

  Since the solvent or solvent composition for producing the multilayer ceramic component of the present invention contains the above alkylene glycol dialkyl ether and / or dialkylene glycol dialkyl ether (compound represented by the above formula (1)), a coating paste such as ethyl cellulose. The binder resin to be blended can be easily dissolved, and the polyvinyl acetal resin such as polyvinyl butyral, which is the binder resin forming the coated surface member, is not dissolved. Therefore, the effect of suppressing or preventing the sheet attack phenomenon can be exhibited. In addition, the alkylene glycol dialkyl ether and dialkylene glycol dialkyl ether are obtained by mixing the binder resin into a coating paste obtained by mixing a conductive metal material such as nickel or palladium or a ceramic material and a binder resin such as ethyl cellulose. Appropriate initial shear viscosity can be imparted without increasing the amount, fine patterns can be accurately formed by each printing method, and it is possible to cope with finer wiring / coating pattern and higher density wiring. .

  Furthermore, high initial shear viscosity can be imparted to the paste containing a binder such as ethyl cellulose by means of alkylene glycol dialkyl ether and dialkylene glycol dialkyl ether, so that the amount of binder resin added can also be reduced. As a result, it becomes possible to reduce the amount of residue derived from the binder resin produced by firing, which hinders the material function. Furthermore, since the alkylene glycol dialkyl ether and dialkylene glycol dialkyl ether have a low boiling point, they can be dried quickly even under low temperature conditions, and the drying time can be shortened. Thereby, softening and deformation of the coated surface member in the heat drying process can be prevented, and the production efficiency of the multilayer ceramic component obtained by highly laminating the coated surface member after drying can be remarkably improved. .

It is a figure which shows the relationship between the shear viscosity in 25 degreeC, and a shear rate about the 5 weight% ethylcellulose solution obtained by melt | dissolving 5 weight% of ethylcellulose in the solvent for multilayer ceramic components manufacture or a solvent composition.

  The solvent or solvent composition for producing a multilayer ceramic component according to the present invention can sufficiently exhibit the binder performance of a binder resin such as ethyl cellulose, and does not cause erosion to the coated surface member. In addition, the binder resin is excessively added to the coating paste obtained by mixing a conductive metal material such as nickel or palladium or a ceramic material and a binder resin such as ethyl cellulose in the solvent or solvent composition for producing the laminated ceramic component. Even if it is not added or even if the amount of binder resin added is reduced, an appropriate initial shear viscosity can be imparted, depending on the printing method used when coating on a green sheet to form a wiring / coating film. Can be adjusted easily.

  For example, in the case of a coating paste for gravure printing, one having a low initial shear viscosity is preferable, and the amount of binder resin added can be reduced compared to the case of using a conventional solvent composition, and a fine pattern can be formed with high accuracy. And while being able to respond to refinement | miniaturization of wiring and a coating-film pattern, and high-density wiring, since the residue of the binder resin produced at the time of baking can be reduced, a conductive fall can be prevented.

Further, in the case of a coating paste for screen printing, one having a higher initial shear viscosity than that for gravure printing is preferable. For example, the initial shear viscosity at 25 ° C. is 1200 mPa · s or more (in particular, 1500 mPa · s or more, In particular, 1800 mPa · s or more) is preferable. If the initial shear viscosity at 25 ° C. of the coating paste is below the above range, the elasticity becomes too low and it becomes difficult to form a fine pattern with high accuracy. When the multilayer ceramic component manufacturing solvent or solvent composition according to the present invention is used as a coating paste, the initial shear viscosity can be easily imparted without forming an excessive amount of a binder resin, and a fine pattern can be formed with high accuracy. In addition, it is possible to cope with finer wiring and coating pattern and higher density wiring, and it is possible to prevent an increase in the binder resin residue generated during firing, and to suppress a decrease in conductivity due to the binder resin residue. be able to. The initial shear viscosity in the present invention is the shear viscosity (mPa · s) at zero point of the shear rate (s ⁻¹ ) obtained by drawing an approximate line on a graph showing the relationship between the shear viscosity at 25 ° C. and the shear rate. is there.
