る。BACKGROUND ART As a method for molding ceramics, there is a method of laminating and molding green sheets made by thinly applying ceramic slurry to a carrier film using a doctor blade or the like. In this method, the adhesion between the stacked green sheets is important for forming the ceramic. It is known that the amount of plasticizer present in the sheet greatly influences the lamination adhesion of the ceramic green sheet.

加していた。Figure 2 shows the conventional process of stacking and adhering green sheets. Plasticizer is ceramic raw material powder φ binder resin.
It is put into a dispersion machine together with a solvent, and is kneaded and dispersed to create a slurry. This slurry is thinly applied onto a carrier film, and the dried green sheet is rolled up and stored. Next, in the lamination process, the green sheets were cut, peeled off from the carrier film, laminated, and pressed together repeatedly to achieve the desired thickness. Conventionally, in the green sheet lamination process, a large amount of plasticizer has been added to the slurry so that the sheet surface has sufficient lamination adhesion.

がる。Problems to be solved by the invention In the conventional technology, plasticizer is added in a slurry state.
In the green sheet 1, the plasticizer 40 exists uniformly in the thickness direction within the sheet 1 as shown in FIG. Therefore, the amount of plasticizer required to obtain a certain level of sheet lamination adhesion is required to be approximately the same as that of the binder resin. When the sheet laminate is fired to form the sintered body 8, this large amount of plasticizer 40 causes the degreasing process to take a long time and the degreasing to be insufficient, as shown in FIG. This leads to the generation of void 7.

える影響は非常に大きい。In addition, in the conventional technology, the plasticizer volatilizes during the solvent drying process after applying the slurry, resulting in poor sheet lamination adhesion, and delamination 8 (delamination) in the sintered body 6 during firing, as shown in FIG. leading to the occurrence of In particular, the thinner the sheet, the greater the amount of volatilization, which will become a bigger problem in the future direction of sheet thinning. Since the volatilization of the plasticizer from the sheet occurs on the sheet surface, it has a very large effect on the lamination adhesion.

する。As in the process shown in FIG. 1, a slurry is prepared by adding no plasticizer or adding less than the amount conventionally required. A method in which this slurry is applied onto a carrier film to form a ceramic green sheet, and after this sheet is dried, a plasticizer is added to the sheet surface immediately before the sheet is cut, peeled, and laminated to laminate the ceramic green sheet. Use. There are two methods of adding plasticizer to the sheet surface: one is to apply a plasticizer solution dissolved in a solvent that does not dissolve the binder resin and is easy to dry, and the other is to spray the plasticizer directly onto the sheet surface. Can be mentioned. In this way, the problem is solved by using a method of imparting lamination adhesion to the sheet using a plasticizer added to the sheet surface.
