DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for applying a water-permeable resin pavement to a sidewalk or the like.

[0002]

2. Description of the Related Art As a pavement such as a sidewalk, a resin pavement in which an aggregate is solidified with resin on open-grained ascon or concrete has been used. This resin pavement is made of natural stone, quartzite, colored porcelain,
It is made by mixing aggregates such as spherical ceramics with pavement resin such as epoxy resin and constructed in layers on roads, etc., and has the advantage of being able to freely select the type and color of aggregates and having water permeability. There is.

[0003] However, the aggregate used for resin pavement is sorted by sieving in order to obtain the desired particle size. However, when the aggregate is sorted after pulverization, a large amount of undesired particle size is generated. The granulation efficiency of the aggregate is extremely poor. On the other hand, in the case of rolling granulation, there is a drawback that the granulation efficiency is poor because it is necessary to repeat the selection and the granulation.

When the size of the sieve is increased to increase the granulation efficiency of the aggregate, the average particle size of the aggregate fluctuates and the quality of the aggregate varies, and the aggregate obtained in this way has a large particle size. Due to the width, even when mixed with a resin and laid in layers, there is a problem that the water permeability is lower than in the case of a single-grain aggregate.

[0005]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention provides a resin pavement having high granulation efficiency of aggregate and having extremely high water permeability as compared with the prior art. An object of the present invention is to provide a method of paving a conductive resin.

[0006]

In order to achieve the above object, the present invention provides a method for paving a water-permeable resin, comprising the steps of: forming a ceramic material paste into a substantially constant diameter within a range of 1 to 6 mm; Are extruded and granulated into a column shape or a prism shape of 1 to 4 and fired to obtain fired ceramic particles, and thereafter, a resin is mixed with the fired ceramic particles to form a layer. In the present invention,

[0007]

The aggregate used in the present invention is composed of fired ceramic particles, and a ceramic raw material paste obtained by mixing and kneading feldspar, pottery stone, clay, pigment, etc., is extruded into a columnar or prismatic column having an almost constant diameter. It is obtained by cutting into an arbitrary length during or after the drying step and baking.

The raw material paste may be used for the production of ceramic products such as porcelain and ceramics, for example, tiles, and is extruded into a cylindrical or prismatic column having a substantially constant diameter according to a known extrusion molding method. . If the extrusion diameter at the time of extrusion molding is less than 1 mm, the molding efficiency is poor, and the extrusion diameter is 6 mm.
Exceeding the molding efficiency is good, but the pavement surface after construction becomes rough, so the extrusion diameter is in the range of 1 to 6 mm, preferably 1.5.
The diameter is set to be substantially constant within a range of ４4 mm.

The raw material paste extruded into a cylindrical or prismatic shape is cut into arbitrary lengths during or after the drying step by a known means, for example, by applying an impact. It is difficult to keep the aspect ratio of the cut particles constant, but if the aspect ratio is more than 4, it will be difficult not only to press and spread the work during construction, but also to break the aggregate at that time. The aspect ratio is 1
４4, preferably 3 or less.

[0010] The ceramic particles obtained by extrusion granulation are fired at a temperature and for a time according to the composition and the like to become fired ceramic particles to be used as aggregates for pavement. If the ceramic fired particles thus obtained have a large number of pores, the amount of the resin used increases and the strength is unfavorable. Therefore, it is preferable to fire the ceramics so that the water absorption is 5% or less.

The aggregate thus obtained is made of ceramics such as porcelain or pottery, and is made of cylindrical or prismatic fired particles having a predetermined diameter and an aspect ratio and having substantially the same size. . Accordingly, the diameter is constant and hardly varies, and the loss of the aggregate due to the sorting is extremely small, so that the granulation efficiency of the aggregate is very excellent.

Although the aspect ratio of the aggregate has some variation, it is surprising that the resin pavement obtained by using the aggregate has a conventional single-grain size granular bone. It was found to exhibit excellent water permeability equal to or higher than that of the resin pavement using the material, specifically, to have a water permeability coefficient of 4 × 10 ⁻¹ cm / sec or more.

In the method of the present invention, such aggregates are mixed with a commercially available pavement resin such as an epoxy resin in a usual ratio, and the mixture is applied in a layered manner according to a usual resin pavement application method, thereby having excellent water permeability. A resin pavement can be formed.

[0014]

Example 1 After adjusting the water content of a commercially available tile material to a water content suitable for extrusion, this was extruded into a columnar shape having a diameter of 1.8 mm as a raw material paste, dried and subjected to an impact to impart an aspect ratio. Was cut such that the main body was 2. By firing the obtained columnar particles so that the water absorption is 5% or less,
An aggregate having a diameter of about 1.5 mm, an aspect ratio of 1 to 3 and a main body of 2 was obtained. The yield in the granulation step during this time was 95%.

Next, 93 parts by volume of the aggregate and 7 parts by volume of the epoxy resin were mixed and applied in a layered manner as usual.
The obtained resin pavement had an excellent texture in appearance, and its water permeability was 5 × 10 ⁻¹ cm / sec.

COMPARATIVE EXAMPLE 1 Commercially available No. 3 silica sand (6 to 20 mesh) having an average particle size of 1.5 mm was used as an aggregate, and 93 volume parts of this aggregate were epoxy resin 3
When the capacity part was added and mixed, and the work was performed in the same manner as in Example 1, the work could be performed without any problem. However, the water permeability of the obtained resin pavement was an extremely low value of 2 × 10 ⁻¹ cm / sec.

Example 2 After adjusting the moisture content of a commercially available tile material to a moisture content suitable for extrusion, this was extruded into a columnar shape having a diameter of 1.8 mm as a raw material paste, dried, and subjected to an impact to adjust the aspect ratio. Cutting was performed so that the main body was 3. The obtained columnar particles were fired in the same manner as in Example 1 to obtain an aggregate having a diameter of about 1.5 mm, an aspect ratio of 2 to 4, and a main constituent of 3.
The yield in the granulation step during this time was 95%.

Next, 93 parts by volume of the aggregate and 7 parts by volume of the epoxy resin were mixed and applied in layers in the same manner as in Example 1. As a result, although a small amount of adhesion to the iron was observed, it could be spread evenly. The resulting resin pavement had an excellent appearance and a water permeability of 6 × 10 ⁻¹ cm / sec.

Example 3 After adjusting the water content of a commercially available tile material to a water content suitable for extrusion, this was extruded into a 4 mm-diameter column as a raw material paste, dried, and subjected to an impact to adjust the aspect ratio. It was cut to obtain 2. The obtained columnar particles were fired in the same manner as in Example 1 to obtain an aggregate having a diameter of about 3.5 mm, an aspect ratio of 1 to 3, and a main constituent of 2. The yield in the granulation step during this time was 95%.

Next, 93 parts by volume of this aggregate and 7 parts by volume of the epoxy resin were mixed and applied in layers in the same manner as in Example 1. As a result, they could be uniformly spread without sticking to the iron, and thus obtained. The resin pavement had an excellent texture in appearance, and its water permeability was 5 × 10 ⁻¹ cm / sec.

COMPARATIVE EXAMPLE 2 After adjusting the water content of a commercially available tile material to a water content suitable for extrusion, this was extruded as a raw material paste into a columnar shape having a diameter of 1.8 mm. Cutting was performed so that the number of subjects was 4 or more. The obtained columnar particles were fired in the same manner as in Example 1 to obtain an aggregate having a diameter of about 1.5 mm and a main body having an aspect ratio of 4 or more. The yield in the granulation step during this time was 97%.

Next, 93 parts by volume of this aggregate and 7 parts by volume of the epoxy resin were mixed and constructed in the same manner as in Example 1.
Adhesion to the iron was remarkable, and it was difficult to spread the layer uniformly. Although the resulting resin pavement was not satisfactory as a road pavement due to severe unevenness, the permeability was 7%.
The value was as high as × 10 ^-1 cm / sec.

[0023]

According to the present invention, the granulation efficiency of the aggregate is very high, so that the waste of the aggregate raw material can be eliminated, and the appearance has an unprecedented superior texture. A resin pavement having extremely high water permeability as compared with the resin pavement described above can be obtained.
