2. Description of the Related Art Conventionally, permeable pavement materials (including those generally referred to as permeable horizontal plates, permeable plates, and permeable pavement boards, including those having irregularities on the surface and those having a flat surface) have been used as aggregates. Gravel, sand, slag, colored glass, crushed rubber, urethane chips, shells, porous volcanic rock, tourmaline ore, etc. are mixed with cement, epoxy resin, tar, asphalt, urethane resin, vinyl acetate resin as an adhesive, After compression molding, it was manufactured by solidifying or mixing and firing with water glass. Among the raw materials of the above-mentioned aggregates, gravel, sand, slag, colored glass, crushed rubber, urethane chips, etc. are recycled products in some cases.

[0003]

These permeable pavement materials are
When it is discarded after use, there is a problem that it cannot be treated as industrial waste because the permeable pavement material itself is not considered for recycling. Further, these pavement materials have a problem that even if a defective product having a size smaller than a predetermined size is generated after being solidified, recycling of the water-permeable pavement material itself is not taken into consideration, and therefore the pavement material can only be treated as industrial waste. That is, an object of the present invention is to provide a water-permeable pavement material that can be recycled and a method for producing the same.

[0004]

[Means for Solving the Problems] As an adhesive, a thermoplastic resin that softens and fluidizes when heated is used as a material, and an aggregate is reused by reheating an inorganic material such as a waste material of tile porcelain or a waste glass material. By using a material that can
Provide recyclable water-permeable pavement material.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION FIG. 1 shows the structure of a recycled ceramics permeable pavement material of Example 1. a is a block-shaped permeable pavement material, for example, a thickness of 60 to 80 mm, a length of 300 mm,
The width is 300 mm. The aggregate b is joined with an adhesive to provide water permeability by providing a water-permeable gap c between the aggregates. As the aggregate b, waste glass or waste material of tile porcelain is used. The material is not limited to the above materials as long as it can be reheated and reused. As the adhesive, a thermoplastic resin that softens and fluidizes when heated is used. For example, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate, nylon,
Examples thereof include polypropylene, polyethylene, polyphenyl ether, polystyrene, methacrylic resin, polyamide, polyacetal, and acrylonitrile-butadiene-styrene resin (ABS). In particular, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polycarbonate, nylon, polypropylene, and polyethylene can be recycled products used for other purposes. The thermoplastic resin is not limited to these examples, and any other resin may be used as long as it is a thermoplastic resin. In the water-permeable pavement material a in FIG. 1, aggregate b
Was used waste glass and tile porcelain waste, and polyethylene terephthalate (PET) resin was used as the adhesive.

[Embodiment 1] A manufacturing method will be described with reference to the manufacturing process chart of FIG. As the aggregate b, waste of hard ceramic material such as magnetic tiles and waste glass are used at a weight ratio of 90:10, and a crushed material having a particle diameter of about 0.01 to 10 mm is used (process 1). As the polyethylene terephthalate (PET) resin, pellets having an average particle size of 1 mm or less were used. This aggregate b
The polyethylene terephthalate (PET) resin was used after being kept at 140 ° C to 150 ° C for 5 hours or more to prevent residual water (Processes 2 and 3). When water remains, it causes a hydrolysis reaction with the polyethylene terephthalate (PET) resin and causes strength deterioration. Therefore, the water was prevented from remaining as much as possible. It is desirable that the water content be 100 ppm or less. This aggregate b is polyethylene terephthalate (PET)
Heat to the resin melting point of 245 ° C to 290 ° C (process
Four). At 245 ° C or lower, the adhesiveness of the polyethylene terephthalate (PET) resin cannot be exhibited because it is below the melting point. 2
Above 90 ℃, polyethylene terephthalate (PET) resin decomposes and is not suitable for use.

Polyethylene terephthalate (PET) resin is mixed in the heated aggregate b in an amount of 2 to 30 wt% (inner ratio: the same applies hereinafter) and poured into a mold frame having a thickness of 60 mm and a size of 300 mm × 300 mm (process 5). If it is less than 2 wt%, good adhesion cannot be obtained, and therefore molding is difficult. When it is 30 wt% or more, the amount of polyethylene terephthalate (PET) resin is excessive, and the water permeability as a water permeable pavement material cannot be secured. To ensure the smoothness of the surface layer when pouring, 3.9 × 10 ^{6 to} 9.8 × 10 ⁷ Pa (40 to 1
000kgf / cm ² ) is pressed (Process 6). 3.9 x 1
Molding is difficult at pressures below 0 ⁶ Pa (40 kgf / cm ² ).
Even if it is molded, appropriate strength cannot be obtained. 9.8
At a pressure of × 10 ⁷ Pa (1000 kgf / cm ² ) or more, the space of the aggregate b is crushed and water permeability cannot be ensured. The mold is at room temperature.
Cool at room temperature, solidify, and remove from mold (process 7, 8). Table 1 shows the three-point bending strength, water permeability, and slip resistance of the ceramics permeable pavement material a obtained in Example 1. The 3-point bending strength was measured according to the test method of JIS A-5304 "Pavement concrete flat plate". The water permeability was measured according to JASS 7 M101 "Interlocking block quality test" of the Japan Institute of Architecture. Regarding the slip resistance, the slip resistance was measured by a portable tester according to ASTM E303.

【table 1】

From the results shown in Table 1, equivalent performance was obtained as compared with the conventional water-permeable pavement material that does not take recycling into consideration.
Furthermore, in the case of Example 1, it was possible to add defective products such as dimensional defects in the aggregate mixing and heating steps. Therefore, the yield rate for the raw material at the final stage could be significantly improved. Furthermore, when conventionally molded with a thermosetting resin, curing time of about several hours was required until it solidifies after press molding, whereas when the thermoplastic resin of the present invention is used, the molding material has a resin temperature It is possible to take out the formwork sufficiently with a curing time of a few minutes, as shown below. Therefore, the manufacturing running time can be shortened and the manufacturing cost can be reduced.

FIG. 3 shows the structure of the recycled ceramics water-permeable pavement material a of Example 2. As the aggregate b, waste glass and tile porcelain waste materials were used. Polybutylene terephthalate resin (PBT) was used as the adhesive. Water-permeable pavement material a
It has a two-layer structure of d and lower layer e. In the surface layer d, the amount of the waste glass mixed was 10 wt% or less of the waste material of the tile porcelain. As a result, a large amount of waste material of the tile porcelain having a higher strength and a higher frictional resistance than the waste glass is contained, so that the frictional resistance increases. The surface layer d has a thickness of 5 to 20 mm, and the lower layer e has a thickness of 40 to 75 m.
The m, length and width are each 300 mm.

[Embodiment 2] FIG. 4 shows a manufacturing method according to a manufacturing process chart. The surface hard material used as the surface layer d uses waste of hard ceramic materials such as magnetic tiles, and the particle size is
Use a crushed product of about 0.01 to 10 mm (process 17). In order to improve the slip resistance of the surface layer, the waste of ceramic material is 90 wt% and the waste glass is 10 wt%.
It was set to wt% or less (process 20). As the aggregate of the lower layer e, waste of hard ceramic material such as magnetic tiles and waste glass are used, and crushed material having a particle size of about 0.01 to 10 mm is used.
(Process 10). The mixing ratio was 20:80 by weight. Polybutylene terephthalate (PBT) resin has an average particle size of 1 mm
The following pellets were used. This aggregate and polybutylene terephthalate (PBT) resin were used after being kept at 120 ° C to 150 ° C for 3 hours or more to prevent residual water.
(Process 11, 12). When water remains, it causes a hydrolysis reaction with the polybutylene terephthalate (PBT) resin and causes strength deterioration. Therefore, the water was prevented from remaining as much as possible. It is desirable that the water content be 100 ppm or less. This aggregate is heated to the melting point of PBT resin, 225 ° C. to 270 ° C. (process 13). At 225 ° C or lower, the adhesiveness of the PBT resin cannot be exhibited because it is below the melting point. Above 270 ° C,
Not suitable for use because PBT resin decomposes. 2-30 wt% PBT resin is mixed with heated aggregate b, thickness 60 mm, 300 mm x 300
Pour into a mm square formwork (process 13-14). If it is less than 2 wt%, good adhesion cannot be obtained, and therefore molding is difficult. Above 30 wt%, polybutylene terephthalate (PBT)
Since the amount of resin is excessive, the water permeability as a water permeable pavement material cannot be secured. In order to ensure the smoothness of the surface layer d during pouring, a pressure press of 3.9 × 10 ^{6 to} 9.8 × 10 ⁷ Pa (40 to 1000 kgf / cm ² ) is performed (process 15). 3.9 × 10 ⁶ Pa (40kgf / cm ² )
Molding is difficult with the following pressures. Even if it is molded, appropriate strength cannot be obtained. 9.8 × 10 ⁷ Pa (1000kgf /
Above cm ² ), the space of the aggregate b is crushed and water permeability cannot be secured. The formwork is at room temperature. After pouring the aggregate of the lower layer e, press-molding and cooling and solidifying, the aggregate b of the surface layer d is pouring-pressing, cooling and solidifying, and taking out from the mold to obtain a two-layer ceramic permeable pavement material a ( process
16-24).

Point bending strength is JIS A-5304 "Pavement concrete flat plate"
It carried out according to the test method of. Regarding the water permeability, it was carried out in accordance with JASS 7 M101 "Interlocking block quality test" of the Japan Institute of Architecture. Regarding the slip resistance, the slip resistance was measured by a portable tester according to ASTM E303.

[Table 2]

The same performance was obtained as compared with the conventional water-permeable pavement material that did not take recycling into consideration. Further, in the case of Example 2, it was possible to add defective products such as defective dimensions to the aggregate mixing and heating steps again. Therefore, the yield rate for the raw material at the final stage could be significantly improved. Surface
By using waste of hard ceramic material such as magnetic tile for d, the strength was improved by 10% and the slip resistance was increased. Furthermore, when conventionally molded with a thermosetting resin, curing time of about several hours was required until it solidifies after press molding, whereas when the thermoplastic resin of the present invention is used, the molding material has a resin temperature It is possible to take out the formwork sufficiently with a curing time of a few minutes, as shown below. Therefore, the manufacturing running time can be shortened and the manufacturing cost can be reduced.

FIG. 5 shows a ceramic permeable pavement material a of Example 3
Shows the structure of. As the aggregate b, waste glass and tile porcelain waste materials were used. As the adhesive, a material obtained by pulverizing waste polyethylene terephthalate resin (PET) recycled from a beverage container or the like to an average particle size of about 1 mm was used. Water-permeable pavement material a

The surface layer d has a thickness of 5 to 20 mm, the lower layer e has a thickness of 40 to 75 mm, the wire mesh has 1 to 10 layers, and the length and width are 3 respectively.

It is a shape in which thin plates intersect each other, for example, a wire mesh, a grating material, and a fence material. For the adhesive, waste polyethylene terephthalate (PE
T) A material obtained by crushing a resin to an average particle size of about 1 mm was used.
In particular, among the waste polyethylene terephthalate (PET) resins, colored ones are suitable for the use of the present invention because they cannot be reused in beverage containers and can only be incinerated.

[Embodiment 3] A manufacturing method will be described with reference to the manufacturing process chart of FIG. The surface hard material used as the surface layer d uses waste of hard ceramic materials such as magnetic tiles, and the particle size is

Use a crushed product of about 0.01 to 10 mm (process 30). The mixing ratio was 20:80 by weight. Polyethylene terephthalate (PET) resin is collected from a beverage container and has an average particle size of 1 mm.
The crushed product was used in the form of pellets. In particular, among the waste polyethylene terephthalate (PET) resins, colored ones are suitable for use in the present invention because they cannot be reused in beverage containers and can only be incinerated. Wire mesh f has a wire diameter of 1.8 m
m, mesh 18 mm crimp wire mesh (a mochi wire mesh grid) was used. This aggregate b, wire mesh f,
Waste polyethylene terephthalate (PET) resin was used after being held at 140 ° C to 150 ° C for 5 hours or more to prevent residual water (process 31 to 35). If water remains,
Since it causes a hydrolysis reaction with polyethylene terephthalate (PET) resin and causes strength deterioration, we tried to keep as little water as possible. It is desirable that the water content be 100 ppm or less. This aggregate b is heated to 245 ° C. to 290 ° C. which is the melting point of polyethylene terephthalate (PET) resin (process 33). At 245 ° C or lower, the adhesiveness of the polyethylene terephthalate (PET) resin cannot be exhibited because it is below the melting point. Above 290 ℃, polyethylene terephthalate (PET)
Not suitable for use because the resin decomposes.

Polyethylene terephthalate (PET) resin is mixed in an amount of 2 to 30 wt% with the heated aggregate b, and the mixture is poured into a mold having a thickness of 60 mm, 300 mm × 300 mm square (1 to 10 layers of wire mesh f is installed). Process 36). For 10 layers or more, the aggregate b
Since it becomes difficult to flow in, a good adhesive effect cannot be obtained. If less than 2 wt%, good adhesion cannot be obtained,
Molding is difficult. When it is 30 wt% or more, the amount of polyethylene terephthalate (PET) resin is excessive, and the water permeability as the water permeable pavement material a cannot be secured. To ensure the smoothness of the surface layer d when pouring, 3.9 × 10 ^{6 to} 9.8 × 10 ⁷ Pa (40 to 1000

^{0 7 Pa (1000kgf / cm 2} ) or more, can not be ensured permeability will collapse the space aggregate b. The formwork is at room temperature. After pouring the lower layer aggregate b, mold pressing and cooling to solidify, the surface layer aggregate b is poured and pressed to cool and solidify, and taken out from the frame to obtain a wire mesh reinforced ceramic water-permeable pavement material a. (Process 43-46). This Example 3 is shown in Table 3.

[Table 3]

The same performance was obtained as compared with the conventional water-permeable pavement material that did not take recycling into consideration. Further, in the case of Example 3, it was possible to remove defective products such as defective dimensions by removing the wire netting f and adding them again to the aggregate mixing and heating steps. Therefore, the yield rate for the raw material at the final stage could be significantly improved. By using the reinforcement in the wire net h, the strength was improved by about 10%. Although the crimp wire mesh was used for the reinforcing material for the time being, there is no problem with wire meshes of other structures, and the same reinforcing effect will be exhibited if a metal material other than the metal mesh has an opening in which the wire of the wire mesh is replaced with a thin plate material. It is possible. Furthermore, when conventionally molded with a thermosetting resin, curing time of about several hours was required until it solidifies after press molding, whereas when the thermoplastic resin of the present invention is used, the molding material has a resin temperature It is possible to take out the formwork sufficiently with a curing time of a few minutes, as shown below. Therefore, the manufacturing running time can be shortened and the manufacturing cost can be reduced. As compared with the conventional method, the strength is improved by stacking the wire nets, and when the wire nets are damaged, scattering of the ceramic permeable pavement material fragments can be prevented due to the presence of the wire nets.

FIG. 7 shows a ceramic permeable pavement material a of Example 4a.
Shows the structure of. As the aggregate b, the ceramic permeable pavement material a manufactured in Example 3 was actually used for one year and crushed into a raw material, and new aggregate b was added to this at a weight ratio of 90:10. Then, an adhesive was added to produce a recycled product. The thickness of the regenerated ceramic layer g is 60 to 80 mm, the wire mesh h is 1 to 10 layers, and the length and width are each 300 mm.

[Embodiment 4] A manufacturing method will be described with reference to the manufacturing process chart of FIG. Used ceramic permeable pavement material
For a, the one from which dust and dirt have been removed through the washing treatment was used (processes 50 to 51). After washing, it was dried at 150 ° C. for 5 hours (process 52). After drying, the wire netting f is locally heated with warm air of 250 ° C. to separate the wire netting f from the ceramics permeable pavement material a (process 53). After separation, average particle size with a crusher
Crushed to a size of about 10 mm and used as recycled material (Process 5
Four). As the aggregate b, waste of hard ceramic material such as a magnetic tile and waste glass are used as the above-mentioned recycled material, and a crushed material having a particle diameter of about 0.01 to 10 mm is used (process 55).
The mixing ratio was 20:80 by weight. The polyethylene terephthalate (PET) resin was recovered from the beverage container, pulverized to an average particle size of 1 mm or less, and pelletized. In particular, among the waste polyethylene terephthalate (PET) resins, colored ones are suitable for use in the present invention because they cannot be reused in beverage containers and can only be incinerated. Wire mesh h is the wire diameter
A 1.8 mm, 18 mm open crimp wire mesh (a mochi wire mesh grid) was used (process 60, 61). This aggregate b, wire mesh h, waste polyethylene terephthalate (PET)
The resin should be heated at 140 ° C-150 ° C to prevent residual moisture.
Used after holding for more than an hour. If water remains,
Since it causes a hydrolysis reaction with polyethylene terephthalate (PET) resin and causes strength deterioration, we tried to keep as little water as possible. It is desirable that the water content be 100 ppm or less. The aggregate b is heated to 245 ° C. to 290 ° C., which is the melting point of polyethylene terephthalate (PET) resin. 245
At below ℃, since it is below the melting point, the adhesiveness of the polyethylene terephthalate (PET) resin cannot be exhibited. Above 290 ° C, polyethylene terephthalate (PET) resin decomposes and is not suitable for use.

This time, the mixing ratio of recycled materials and waste glass
Aggregate b was used as 6: 4. 2 to 30 wt% of polyethylene terephthalate (PET) resin is mixed with the heated aggregate b, and 1 to 10
Pour the wire mesh h of the layer into a mold of 60 mm thick and 300 mm × 300 mm square (process 62). When the number of layers is 10 or more, it is difficult for the aggregate b to flow into the inside of the wire netting h, so that a good adhesive effect cannot be obtained. If it is less than 2 wt%, good adhesion cannot be obtained, and therefore molding is difficult. When it is 30 wt% or more, the amount of polyethylene terephthalate (PET) resin is excessive, and the water permeability as a water permeable pavement material cannot be secured. To ensure the smoothness of the surface layer when pouring, 3.9 × 10 ^{6 to} 9.8 × 10 ⁷ Pa (40 to
A pressure press of 1000 kgf / cm ² ) is performed (process 63). 3.9 x 1
Molding is difficult at pressures below 0 ⁶ Pa (40 kgf / cm ² ).
Even if it is molded, appropriate strength cannot be obtained. 9.8
At a pressure of × 10 ⁷ Pa (1000 kgf / cm ² ) or more, the space of the aggregate b is crushed and the water permeability cannot be secured. The formwork is at room temperature.
The aggregate b was poured and pressed, cooled and solidified, and taken out from the frame to obtain a wire mesh-reinforced ceramic permeable pavement material a with a two-layer structure (processes 62 to 65). Table 4 shows the three-point bending strength, water permeability, and slip resistance of the ceramic water-permeable pavement material a obtained in Example 4. The three-point bending strength was measured according to the test method of JIS A-5304 "Pavement concrete flat plate". Regarding the water permeability, the Japan Institute of Architecture JASS 7 M101
It measured according to the "interlocking block quality test." Regarding the slip resistance, the slip resistance was measured by a portable tester according to ASTM E303.

[Table 4]

The same performance was obtained as compared with the conventional water-permeable pavement material that did not take recycling into consideration. Furthermore, in the case of Example 4, it was possible to remove the wire mesh from defective products such as defective dimensions and to add them again to the aggregate mixing and heating steps. Therefore, the yield rate for the raw material at the final stage could be significantly improved. By using the reinforcement in the wire net h, the strength was improved by about 10%. Although the crimp wire mesh was used for the reinforcing material for the time being, there is no problem with wire meshes of other structures, and the same reinforcing effect will be exhibited if a metal material other than the metal mesh has an opening in which the wire of the wire mesh is replaced with a thin plate material. It is possible. Furthermore, when molded with conventional thermosetting resin,
While curing time of several hours was required until solidification after press molding, when the thermoplastic resin of the present invention was used, a curing time of several minutes at which the molding material was below the resin temperature was sufficient for molding. The frame can be taken out. Therefore, the manufacturing running time can be shortened and the manufacturing cost can be reduced.
As compared with the conventional method, the strength is improved by stacking the wire nets, and when the wire nets are damaged, scattering of the ceramic permeable pavement material fragments can be prevented due to the presence of the wire nets.

As compared with the conventional water-permeable pavement material that does not take recycling into consideration, the same performance is obtained. Further, when the thermosetting resin is used, it is possible to take out the mold sufficiently within a curing time of about several minutes when the temperature of the molding material becomes equal to or lower than the resin temperature. Therefore, the manufacturing running time can be shortened and the manufacturing cost can be reduced. Also, by stacking wire mesh,
When the strength is improved and further broken, there is a wire mesh, which makes it possible to prevent the scattering of the ceramic permeable pavement material fragments.
