背景技术 Background technique
叠层电容器一般是经过下面的步骤制造的。首先，在有机溶剂中溶解聚乙烯醇缩丁醛或丙烯酸树脂的粘合树脂，加入陶瓷进行混合。进而将该混合物形成薄片状，获得生片(グリ一ンシ一ト)。A multilayer capacitor is generally manufactured through the following steps. First, polyvinyl butyral or acrylic resin binder resin is dissolved in an organic solvent, and ceramics are added and mixed. Furthermore, this mixture was formed into a sheet form to obtain a green sheet.
接着，将以镍、钯等导电性金属材料、乙基纤维素和萜品醇等有机溶剂作为主要成分的电介质浆料通过网板印刷法等涂布在生片上，形成配线。Next, a dielectric paste mainly composed of a conductive metal material such as nickel and palladium, and an organic solvent such as ethyl cellulose and terpineol is coated on the green sheet by screen printing or the like to form wiring.
进而，干燥上述电介质浆料中的溶剂，以一定尺寸裁断形成配线的生片，多个板重叠加热施压来叠层。在该叠层体上安装电极等后，高温下烧成，获得叠层电容器。Furthermore, the solvent in the above-mentioned dielectric paste is dried, and the green sheet on which the wiring is formed is cut to a certain size, and a plurality of plates are stacked by heating and pressing. After mounting electrodes and the like on this laminate, it is fired at a high temperature to obtain a multilayer capacitor.
上述步骤中，如果在生片上涂布电介质浆料，有时产生电介质浆料中的有机溶剂将生片中含有的粘合成分溶解的现象。该现象称为片浸蚀(シ一トアタツク)现象。片浸蚀现象是引起叠层陶瓷电容器的陶瓷层上产生洞或摺痕、配线形成不良、短路等产率降低的原因。目前几乎没有因为生片层加厚而在生片上产生缺陷的问题。In the above steps, when the dielectric paste is coated on the green sheet, the organic solvent in the dielectric paste may dissolve the binder component contained in the green sheet. This phenomenon is referred to as the phenomenon of sheet erosion. The chip erosion phenomenon is a cause of yield reduction such as holes or creases in the ceramic layers of multilayer ceramic capacitors, poor wiring formation, and short circuits. At present, there is almost no problem that defects are generated on the green sheet due to thickening of the green sheet layer.
但是，伴随叠层电容器的高容量化、小型化，要求构成装置的陶瓷层的薄层化、多层化。结果，片浸蚀现象显著发生了。However, with the increase in capacity and miniaturization of multilayer capacitors, it is required to reduce the thickness and increase the number of layers of ceramic layers constituting the device. As a result, the sheet erosion phenomenon remarkably occurred.
因而，作为片浸蚀现象的改善方法，正在研究改善使用的有机溶剂的各种方法。例如，在专利文献1中公开了作为有机溶剂，使用萜品醇加氢产物的内容。并且，在专利文献2中公开了使用己酸乙酯、醋酸2-乙基己基酯等溶剂。Therefore, various methods for improving the organic solvent used are being studied as methods for improving the sheet erosion phenomenon. For example, Patent Document 1 discloses the use of a terpineol hydrogenation product as an organic solvent. Furthermore, Patent Document 2 discloses the use of solvents such as ethyl hexanoate and 2-ethylhexyl acetate.
但是，萜品醇是天然物，是α-萜品醇、β-萜品醇和γ-萜品醇的混合物。因此，混合比或纯度会因为产地等而变动。并且，上述萜品醇加氢产物也存在2种异构体，再加上由于源于原料的品质不同，会有不易稳定地抑制片浸蚀现象的情况。此外，使用己酸乙酯、醋酸2-乙基己基酯等溶剂时，由于干燥步骤中温度的上升，溶剂的温度也上升，对于生片中含有的粘合成分的溶解度增加，因此存在不能有效地防止片浸蚀现象等问题。However, terpineol is a natural product and is a mixture of α-terpineol, β-terpineol, and γ-terpineol. Therefore, the mixing ratio and purity vary depending on the production area and the like. In addition, the terpineol hydrogenation product also has two types of isomers, and due to the difference in quality of raw materials, it may be difficult to stably suppress the chip erosion phenomenon. In addition, when solvents such as ethyl caproate and 2-ethylhexyl acetate are used, the temperature of the solvent also rises due to the temperature rise in the drying step, and the solubility of the adhesive components contained in the green sheet increases, so there is a problem that it is not effective. To prevent sheet erosion and other problems.
此外，如果使用以仅仅不溶解粘合树脂为标准的混合溶剂，存在溶剂的沸点和叠层电容器干燥步骤时的加热温度之间的平衡变差，在干燥步骤中耗费时间的情况。In addition, if a mixed solvent is used that only does not dissolve the binder resin, the balance between the boiling point of the solvent and the heating temperature in the drying step of the multilayer capacitor becomes poor, and the drying step may take time.

发明效果Invention effect
使用本发明的溶剂组合物能有效地抑制和防止片浸蚀现象。并且，在制造步骤中无需严格的时间管理，能使生片进一步薄膜化。而且，因为三乙酸甘油酯是合成品，品质稳定，毒性低，臭味少，从操作安全上考虑容易操作。The use of the solvent composition of the present invention can effectively suppress and prevent the sheet erosion phenomenon. In addition, it is possible to further reduce the thickness of the green sheet without strict time management in the production steps. Moreover, because triacetin is a synthetic product, it has stable quality, low toxicity, and less odor, and is easy to handle in terms of operational safety.
具体实施方式 Detailed ways
在本发明的溶剂组合物中使用的三乙酸甘油酯，单独存在时具有不溶解乙基纤维素、聚乙烯醇缩丁醛和丙烯酸树脂粘合树脂的性质。因此，本发明中，通过混合三乙酸甘油酯以外的溶剂(下面称为“溶剂A”。)，发挥对于乙基纤维素的充分的溶解性。Glyceryl triacetate used in the solvent composition of the present invention, when present alone, has the property of not dissolving ethyl cellulose, polyvinyl butyral and acrylic binder resins. Therefore, in the present invention, sufficient solubility with respect to ethyl cellulose is exhibited by mixing a solvent (hereinafter referred to as "solvent A") other than triacetin.
此外，如果在三乙酸甘油酯中混合其他溶剂，可显示对于乙基纤维素充分的溶解性，但是因为对于聚乙烯醇缩丁醛和丙烯酸树脂几乎不显示溶解性，因此能有效地抑制片浸蚀现象。In addition, if triacetin is mixed with other solvents, it can show sufficient solubility for ethyl cellulose, but since it shows little solubility for polyvinyl butyral and acrylic resin, it can effectively suppress sheet leaching. erosion phenomenon.
因而，本发明中作为在三乙酸甘油酯中混合的溶剂，适合使用对于乙基纤维素溶解度高的溶剂，例如乙基纤维素在室温的溶解度为5g/100g以上的溶剂。Therefore, in the present invention, a solvent having a high solubility in ethyl cellulose, for example, a solvent in which ethyl cellulose has a solubility of 5 g/100 g or more at room temperature is suitably used as the solvent to be mixed with triacetin.
而且，作为本发明中在三乙酸甘油酯中混合的溶剂，由于能用通常的电容器制造设备干燥的溶剂的沸点上限为260℃左右，而且三乙酸甘油酯的沸点也是260℃，因此适合使用沸点不到260℃的溶剂。Moreover, as the solvent mixed with triacetin in the present invention, since the upper limit of the boiling point of the solvent that can be dried with ordinary capacitor manufacturing equipment is about 260°C, and the boiling point of triacetin is also 260°C, it is suitable to use a boiling point of 260°C.
