[Technical Field] The present invention relates to a method for manufacturing a glazed inorganic material with a high design quality for use in exterior materials and the like. [Background Art] Conventionally, the surface finishing of concrete panels has usually been done by painting. However, since paints are inferior in weather resistance, chemical resistance, and stain resistance, there is a problem that the painted surface changes color and fades over time, resulting in poor appearance. In order to solve this problem, a method has been proposed in which the surface of the concrete panel is glazed. In other words, a cement mixture made by adding water to cement and aggregate is poured into a predetermined mold and formed, and the surface of the resulting concrete panel is glazed and fired at high temperature to form a ceramic layer. be. However, when a formed concrete panel is dried and then treated with a glaze, problems such as peeling of the glaze occur. [Object of the Invention] An object of the present invention is to provide a method for producing a glazed inorganic material that prevents the occurrence of glaze flaking during glazing treatment. [Disclosure of the Invention] The method for producing a glazed inorganic material of the present invention involves creating an inorganic material in a predetermined shape from an inorganic material material containing aggregate in a dry state, then applying a glaze to the surface of this inorganic material and firing it. It is something to do. In other words, as a result of extensive research into the causes of glaze flaking during glaze treatment, the present inventors found that
It was found that the moisture contained in the aggregate in the inorganic material raw material was involved. This water is difficult to evaporate and cannot be completely removed even by drying, which is the pre-glaze process, so it turns into water vapor in the temperature range where the glaze melts during firing, and the glaze flakes where this water vapor comes out. It was happening. Therefore, in this invention, by using aggregate in a dry state, a good glazed surface can be obtained for glazing treatment, and defective phenomena such as glaze flaking can be eliminated, resulting in a beautiful appearance. A ceramic layer is formed. As the aggregate used, any of the various lightweight aggregates that have been used conventionally can be used. The aggregate may be dried by forced drying using a drying oven or the like, or by natural drying. At that time, the content of aggregate after drying is 4%
The following are effective in preventing glaze flaking, etc. Examples of the inorganic materials include concrete,
Examples include slate and multifoam ceramics.
For example, in the case of concrete, the main raw materials for inorganic materials are cement, aggregate, and water.
After adding water to cement and aggregate and kneading them, they are poured into a mold and shaped. A glaze is applied to the surface of the molded inorganic material. As the glaze, any fritted glaze used for manufacturing tiles, ceramic roof tiles, etc. can be used. After glazing, it is fired. Firing time and temperature are determined depending on the type of glaze, but usually 600-900℃
It takes 5 minutes to 2 hours. After firing, if necessary, the product is immersed in water, cured, and then manufactured. Next, the results of experiments in which the present inventors actually manufactured glazed concrete panels will be explained. A cement mixture prepared by kneading the following ingredients was poured into a predetermined mold (100 mm long, 100 mm wide, 70 mm thick) to form a concrete test specimen. (Components) (Parts by weight) Cement 35.8 Fine aggregate 45.8 Coarse aggregate 18.2 Water 0.51 Water reducing agent 0.2 All aggregates used were inorganic foamed lightweight aggregates (shale-based), and the water content was adjusted as shown in the table below. Test specimens 1 to 6 were created using the respective materials. The molded concrete specimens were dried at 300°C for 5 hours, treated with glaze, fired at 850°C for 1 hour, immersed in water for 30 minutes, and then steam-cured for 3 days. The condition of the glazed surface of the concrete surface thus obtained was observed. The results are shown in the table below.
