[Field of Industrial Application] The present invention relates to a ceramic molding method and a ceramic molding composition. Specifically, a resin emulsion is added to a ceramic base soil or a ceramic base soil to prepare a slurry, and this is The present invention relates to a method for molding ceramics, which is characterized by casting, and a ceramic composition for casting, which is characterized in that a resin emulsion is added to ceramic base soil or ceramic base soil. [Prior art] Conventionally, in slurry casting in ceramic molding, appropriate amounts of water, dispersant, etc. are added to the base soil to prepare slurry, and this slurry is poured into a water-absorbing mold such as a plaster mold. A cast body has been formed by depositing slurry along the mold surface due to water absorption in the mold, and removing the mold after depositing the deposit. This molded body is
After that, it becomes a ceramic product through processes such as drying, bisque firing, glazing, and firing, but when using this method, the cast molded product must have enough mechanical strength to be able to be handled during finishing processing and transportation. It is also necessary that the mold can be easily demolded. [Problems to be solved by the invention] In the past, attempts have been made to give ceramic base clay the mechanical strength necessary for work by adding Frogme clay, Kibushi clay, etc.; It was necessary to impart sufficient mechanical strength to cast molded bodies made of such base clay through bisque firing, and the use of clay was also necessary to impart a transparent feel similar to that of white porcelain. The production of high-quality porcelain has become difficult, and with the depletion of high-quality clay resources, we are facing an even more difficult situation. Under these circumstances, there has been a strong desire to develop a strength improver that can impart sufficient mechanical strength to a cast molded product without using a large amount of clay. If the casting method can be applied to the base soil for ceramics, it will be possible to easily form products with complex shapes, but with the base soil alone, it is difficult to form a cast body with sufficient strength. Therefore, there has been a strong desire for the development of a strength improver that provides cast molded products with sufficient mechanical strength for handling such as finishing and transportation. As a result of repeated research to solve the above-mentioned problems, the present inventors discovered that the mechanical strength of a cast molded product can be improved by using a resin emulsion as a strength improver. Completed the invention. [Means for solving the problems] The present invention provides a method for molding ceramics, which includes:
When slurry casting is performed on ceramic base soil or ceramic base soil, resin emulsion is added to the base soil to improve the strength of the cast molding, simplify the process, and efficiently produce ceramic products of excellent quality. The present invention relates to a ceramic composition for cast molding, in which a resin emulsion is added to a ceramic base clay or a ceramic base soil. In the present invention, the base soil for ceramics refers to materials that have been used as base soils for ceramics, such as feldspar, silica, pottery stone, kaolin, and clay, and the base soil for ceramics refers to alumina base soil. , zirconia, silica, ferrite, silicon carbide, silicon nitride, sialon, and other ceramic raw materials. Resin emulsions include, for example, (meth)acrylic ester resin, (meth)acrylic ester-vinyl acetate resin, (meth)acrylic ester-styrene resin, (meth)acrylic ester-
Acrylic resin emulsion whose main component is vinyl chloride resin, vinyl acetate resin emulsion whose main component is vinyl acetate resin, ethylene copolymer resin system whose main component is ethylene-acrylic acid ester, ethylene-vinyl chloride resin, etc. Synthetic rubber emulsion, natural rubber emulsion, etc. whose main components are emulsion, styrene-butadiene resin, methyl methacrylate-butadiene resin, acrylonitrile-butadiene resin, etc. Among these, acrylic resin emulsions are preferred. The amount of resin emulsion added to ceramic base soil or ceramic base soil varies depending on the type of base soil, the type of resin emulsion, the type of ceramic molded product to be manufactured, etc., and cannot be determined uniformly. No, but usually dry bare soil
An appropriate solid content is about 0.1 to 20 parts by weight per 100 parts by weight. The slurry of the present invention, which is prepared by adding a resin emulsion to ceramic base soil or ceramic base soil, is extremely stable, has low viscosity, has good fluidity, and has excellent moldability. has excellent mechanical strength. The scope of the slurry of the present invention includes not only those consisting of base soil and resin emulsion, but also slurries containing dispersants, other ceramic raw materials, etc. in addition to both components. The cast molded body formed by the method of the present invention has sufficient strength to withstand handling or post-processing as it is without performing a subsequent bisque firing step. Therefore, the bisque firing step may be omitted and the ceramic molded body may be produced by glazing and firing, or, if necessary, the cast molded body may be colored and decorated before being glazed and fired. . [Effects of the Invention] As described above, according to the present invention, in addition to being able to omit steps, making post-processing easy, and expanding the range of usable base materials, the objects of molding can be expanded. , excellent effects such as the production of a ceramic molded body with high strength can be obtained. EXAMPLES The present invention will be specifically explained below with reference to examples, but it goes without saying that these examples are only a small part of the present invention. However, % indicates weight %. Example 1 Water Glass No. 1 was added at 0.41% based on the dry solid content of the base soil to a low viscosity base soil (Marui Ceramic Co., Ltd. product, special grade soil) as a ceramic base soil, and water was added and mixed and stirred to reduce the solid content. A slurry of 68.4% was obtained. Resin emulsion A (acrylic resin emulsion containing styrene-2-ethylhexyl acrylate as the main component, solid content 43%) and B (carboxyl-modified acrylic resin emulsion containing styrene-2-ethylhexyl acrylate as the main component) were applied to this slurry. , solids content 43%), C (styrene-methyl methacrylate-
Synthetic rubber emulsion containing butadiene as the main component, solid content 43%) and D (vinyl acetate resin emulsion containing vinyl acetate as the main component, solid content 43%) were added and mixed as shown in Table 1. Stirring was performed to obtain a homogeneous slurry. This slurry was poured into a plaster mold with a length of 90 mm, a width of 20 mm, and a thickness of 5 mm, left to build up, and then removed from the mold. Then, it was dried at room temperature and 110°C to form a cast mold having the strength shown in Table 1. I got a body. This cast molded body was fired to obtain an excellent ceramic molded body. The strength is Tensilon UTM- manufactured by Toyo Baldwin.
-500 was used to measure the bending strength.

Resin emulsion B was added to this slurry in an amount of 5% by weight based on the dry base soil, and casting was carried out in the same manner as in Example 3. The molding time was 40 minutes, and three drying conditions were used: undried, room temperature drying, and 110°C drying. Table 8 shows the results of measuring the strength of the obtained molded bodies. For comparison, molded articles were obtained in exactly the same manner and their strengths were measured in the case where no resin emulsion was added and in the case where a paraffin wax emulsion was used as the resin emulsion. Parafine wax emulsions use sodium lauryl sulfate as a surfactant, and the solid content is
43% by weight was used. These measurement results are also shown in Table 8.
