Description

[Detailed description of the invention] The present invention aims to solve the following problems.

(Industrial Application Field) This invention relates to flooring materials used on pavements and other surfaces, and more specifically, to water-permeable flooring materials that are water permeable and allow rainwater to seep into the ground. It is related to.

(Prior art) Conventional water-permeable flooring materials that are hardened by molding a large number of aggregates using fine particle cement or resin with many voids left have low surface hardness. Furthermore, since the bending strength is low, there is a problem that it is easily worn out or damaged during use.

Furthermore, conventional shoes tend to absorb dirt when splashed with dirty water, resulting in a problem in that they lose their aesthetic appearance in a short period of time.

(Problems to be Solved by the Invention) This invention eliminates the above-mentioned conventional problems, and has a structure that has high surface hardness and bending strength, can be used robustly, is resistant to staining, and can maintain good appearance for a long period of time. The aim is to provide a water-permeable flooring material with a high level of water permeability.

The configuration of the present invention is as follows.

(Means for Solving the Problems) The present invention takes the measures as described in the claims above, and its effects are as follows.

(Function) Water falling on the surface of the flooring material can pass through a large number of continuous pores formed inside the flooring material.

In this case, since both the aggregate and the molten solidified material in the birth month are glassy, the dirt of the water passing through is less likely to be adsorbed to the aggregate and the molten solidified material. Furthermore, since the above-mentioned flooring material is formed by firing, its surface hardness and bending strength are extremely high.

(Embodiments) The drawings showing the embodiments of the present application will be explained below. In the flooring material A shown in Figure 1, 1 is a granular aggregate such as anti-flinder stone (produced from Niijima, Tokyo), blast furnace slag (ground water), ceramic waste, etc. The material used has the ability to withstand heat and maintain its original shape.

Reference numeral 2 is a molten solidified material that connects a large number of aggregates 1 together. Reference numeral 3 denotes a large number of continuous pores formed between the aggregates, which are formed in a continuous state to allow air, water, etc. to flow between them. 4 is the fourth part on the surface of flooring material A,
Bilateral continuous pores 3 are formed with portions exposed on the surface of the flooring material A.

Next, the manufacturing procedure of the flooring material A described in - will be explained.

(a) After dry crushing aggregate 1 such as anti-flinder rock or blast furnace slag (water granulated), it is passed through an 8 to 40 mesh sieve using a sieve classification method or the like.

(b) After dry crushing general feldspars, glass cullet, and clays (foamstone may be used), they are passed through an 80 to 150 mesh sieve using a sieve classification method, or are passed through a trommel mill. etc. to form a fine particle slurry.

(C,) Weigh, stir, and mix the raw materials with appropriate particle size structure obtained in (a) and (b) above into a predetermined formulation, and if necessary, add an organic binder, water, etc., and thoroughly mix and manufacture. Grind and create clay.

(d) Using the clay obtained in (c) above,
00kg/co! Pressure molding is performed at a pressure of As the cross section of this molded product is shown in FIG. 2, the above aggregate 1, the above raw material (b) and (C)
It is mixed with the particulate raw material 5 consisting of an organic binder etc. added in step 1, and is formed into a dense state by the pressure of two feet.

(8) Dry the molded product to the extent that it will not explode during firing, and
Temperature range from 00°C to 1250'C for 10-30 hours in tunnel kilns and 4 hours in roller hearth kilns.
The above-mentioned flooring material is obtained by firing on a schedule of 0 to 200 minutes. In the firing as described in -, the surface of the aggregate 1 is slightly melted, and the particulate raw material 5 is entirely melted. Then, these molten materials are solidified by cooling after firing in a continuous state, and become a molten solidified material 2 in the floor material A after firing. In this process, the fine particle raw material 5 melts and solidifies, thereby reducing its volume. As a result, as shown in FIG. 1, continuous pores 3 are formed between a large number of aggregates 1.

In addition, when molding clay to obtain a molded product like the two pairs, there are the following effects. That is, since the continuous pores 3 are formed in the floor material A by firing, when molding the -F clay to obtain a molded product, high pressure is applied to form the molded material as shown in Figure 2. There is no problem in molding it into a dense state. Therefore, by molding at such high pressure, the strength of the molded product can be increased, and as a result, when the molded product is transported for firing or put into a kiln,
This has the effect of making it extremely easy to handle.

The floor material A formed as described above is used by being spread on a piece of ground. If it rains and rainwater falls on flooring material A during its use, the rainwater will flow through the continuous pores 3.
It can pass through the flooring material and soak into the ground. Furthermore, if a person walks on the flooring material A in the above-mentioned state of use, the flooring material A may be damaged because it is formed by firing the above-mentioned raw materials in the above-mentioned manner and has a high hardness. Very few things happen. In that case, since many recesses 4 are formed on the surface of the flooring material A, the feet can slip and the user can safely walk on the surface of the flooring material A.

Furthermore, even if fine particles of mud or colored sewage flow on the surface of flooring material A under the conditions of use described above, flooring material A is formed using glass-rich raw materials as aggregate; The molten solidified product 2 is also formed by adjusting the raw materials as described above and is glassy, so that it is difficult to adsorb the dirt and stain. Furthermore, even if it gets dirty, it can be easily cleaned.

Next, a specific manufacturing example will be explained.

Production Example 1 Aggregates and particulate raw materials were stirred, mixed, and granulated in the formulation shown in Table 1 below as described above to prepare clay.

Next, it is fired in a tunnel kiln at 1100°C for 25 hours. The characteristics of the product obtained above are shown in Table 4 below.

Table 4 (Effects of the Invention) As described above, the present invention has the feature that when it rains when it is used spread on the ground, the rainwater is allowed to permeate through the continuous pores 3 and soak into the ground. be.

Furthermore, when used in the manner described above, the water permeable flooring material of the present invention has the advantage of being a fired product, having high surface hardness and bending strength, and being able to be used robustly.

Furthermore, even though water passes through it as described above, since the aggregate 1 is made of a material rich in glass, it is difficult to adsorb mud and colored sewage under the above conditions of use, resulting in less dirt and maintaining a beautiful state for a long period of time. effective.

Moreover, even though the water-permeable flooring material of the present invention has many effects such as ``two feet'', its raw material is a mixture of granular aggregate and fine particle raw material with high moldability.
There is also the advantage that molding can be easily performed during manufacturing.
