Field of the Invention The present invention relates to a method for manufacturing a pavement board, and more particularly to a ceramic pavement board with a hard and beautiful surface, which is used for sidewalks, parks, parking lots, building approaches and the like.
The present invention relates to a method for producing a permeable pavement board that has good walkability because no water pools are formed on the surface when it rains, has good plant growth in the vicinity due to water infiltration, and reduces the sewage treatment load during rainfall. .

Description of the Related Art As an attempt to manufacture a water-permeable pavement board using a ceramic material, for example, there is a pavement board of Japanese Patent Publication No. 62-20321. This pavement board is made by mixing a large number of ceramic shards, glass shards, and sodium silicate and press-molding them, while maintaining the shape due to the adhesiveness of sodium silicate.
By firing at a temperature of 00 ° C. or higher, glass fragments and sodium silicate are melted by heat to bond the ceramic fragments to each other.

るので十分な透水性が得難くなる。Although it seems possible to obtain pavement boards having a considerable water permeability by this method, glass fragments are expensive as a raw material for paving materials. Therefore, in order to obtain long-term durability against breaking load and surface peeling, it is necessary to increase the ratio of glass shards to porcelain shards, which not only makes it an expensive product, but also increases the ratio of glass shards. Since the porosity of is decreased, it becomes difficult to obtain sufficient water permeability.

ことは経済的ではない。Further, when the surface of such a ceramic pavement plate is colored with a pigment, when the pigment is applied only to the surface and baked, the pigment is worn out in a few months after the construction. Further, since the price of pigment is much higher than that of porcelain shards, it is not economical to mix the pigment in the whole porcelain raw material.

板を得ることができる。As shown in the formulation P in Table 1, as the porous ceramic matrix, 5 coarse particles of inorganic raw material having a diameter of 2 mm to 7 mm (in the formulation example P, selben having a grain size of 3 mm to 5 mm) are used.
If a material containing 0% by weight or more is mixed with a small amount of a material having a heat-sealing action (Hatoshi feldspar in Formulation Example P), the material is molded into a plate and baked at an appropriate temperature. Since many through holes are formed at the grain boundaries of the grains, almost uniform water permeability can be obtained over the entire surface of the plate. Increasing the grain size of the raw material grains improves the water permeability, but reduces the smoothness of the product plate surface and increases the required thickness as a porous ceramic substrate when laminated with a dense ceramic substrate. . From the viewpoint of use as a water-permeable pavement board, the particle size of the coarse particles for the porous ceramic base material is suitably 2 mm to 7 mm. Further, when the coarse particles in the raw material are 50% by weight or less, it is difficult to obtain sufficient water permeability. When two or more kinds of coarse particles are used, it is possible to obtain a plate having a beautiful pattern on the surface on which the coarse particles naturally form during molding.

(In this case, the drainage hole may penetrate to the lower layer.) In this case, the width (minor diameter) of the hole is preferably 5 mm or less in order to prevent rush accidents such as high heels and bulk. Further, even when a beautiful glaze is applied to the surface layer, there is an effect of preventing pedestrians and vehicles from slipping due to the number and arrangement of the holes. Furthermore, by using a dense ceramic material also in the lower layer of the peripheral portion of the pavement plate, an inexpensive material having coarser grains can be used as a main raw material inside the lower layer.

Therefore, the cost of the porous ceramic material is relatively high as compared with the case of the product examples 1 and 2. However, since the porous ceramic material penetrates from the front surface to the back surface of the pavement plate, as shown in Table 2, a pavement plate having much better water permeability than that of Product Examples 1 and 2 is obtained. be able to.
