Description

  The present invention relates to an excrement disposal material and a method for producing the same.

  As a conventional excrement processing material, there exists a thing described in patent document 1, for example. The excrement disposal material described in the same document is composed of a plurality of particles having water repellency and is laid on a pet toilet. This pet toilet is partitioned into an upper space and a lower space by a mesh-like sheet through which urine passes. The water-repellent particles are disposed in the upper space. A liquid absorbing sheet is disposed in the lower space. When the pet urinates, the urine passes between the water-repellent particles and reaches the lower space through the mesh sheet. The urine that has reached the lower space is absorbed by the liquid absorbent sheet.

JP 2005-110700 A

  Unlike the water-absorbing excrement disposal material, such a water-repellent excrement disposal material hardly absorbs urine and can be used repeatedly. However, when forming a granular material by granulating a pulverized material, it is necessary to subject the surface of the granular material to a water repellent treatment in order to impart water repellency to the granular material.

  Such a water-repellent treatment is necessary not only when a hydrophilic material such as paper is used, but also when a hydrophobic material such as plastic is used. This is because even if a hydrophobic material is used, a gap is generated between the pulverized materials, and moisture enters the inside of the granular material through the gap. The necessity of the water-repellent treatment as described above is a factor that complicates the manufacturing process of the excrement disposal material.

  This invention is made | formed in view of the said subject, and it aims at providing the excrement processing material which can exhibit water repellency even if it omits water-repellent treatment, and its manufacturing method.

  The excrement disposal material according to the present invention is an excrement disposal material comprising a water-repellent granular material, wherein the granular material is laminated on the first layer and the first layer, and is made of a hydrophobic material. A granulated product of a pulverized material including a laminate material having a second layer, and at least a part of the hydrophobic material that has flowed out of the second layer enters the gap between the pulverized materials. It is characterized by being.

  In this excrement disposal material, the granular material is composed of a granulated material of pulverized material including a laminate material. Then, at least a part of the hydrophobic material constituting the second layer of the laminate material flows out of the second layer and enters the gap between the pulverized materials. Thereby, since the said clearance gap is block | closed with a hydrophobic material, it becomes difficult for a water | moisture content to permeate the inside of a granular material. For this reason, the granular material which has water repellency can be obtained even if it does not perform water repellency processing.

  Further, the method for producing a waste treatment material according to the present invention is a method for producing a waste treatment material comprising a granular material having water repellency, which is laminated on the first layer and the first layer, A preparatory step of preparing a pulverized material including a laminate material having a second layer made of a hydrophobic material, and a granule that forms the granule by granulating the pulverized material prepared in the preparatory step And forming the granular material, wherein at least a part of the hydrophobic material is dissolved.

  In this manufacturing method, the granular material is formed by granulating a pulverized material including a laminate material. And at least one part of the hydrophobic material which comprises the 2nd layer of a laminate material melt | dissolves in a granular material formation process. The dissolved hydrophobic material flows out of the second layer and enters the gap between the pulverized materials. Thereby, in the excrement disposal material after manufacture, since the said clearance gap is block | closed with a hydrophobic material, it becomes difficult for a water | moisture content to penetrate into the inside of a granular material. For this reason, the granular material which has water repellency can be obtained even if it does not perform water repellency processing.

  ADVANTAGE OF THE INVENTION According to this invention, even if a water-repellent process is abbreviate | omitted, the excrement processing material which can exhibit water repellency, and its manufacturing method are implement | achieved.

It is a schematic diagram which shows one Embodiment of the excrement disposal material by this invention. 2 is a side view showing a laminate material that constitutes a granular material 10. FIG. FIG. 4 is a side view showing a state in which a dissolved hydrophobic material flows out from a layer 24 in a laminate material 20.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted.

  FIG. 1 is a schematic view showing an embodiment of the excrement disposal material according to the present invention. The excrement disposal material 1 is an excrement disposal material used for the treatment of human or animal excrement, and includes a granular material 10 having water repellency. The granular material 10 has a property that it does not absorb liquid such as urine at all or hardly absorbs it. This excrement disposal material 1 is used, for example, in a two-stage animal toilet (system toilet) partitioned into an upper space and a lower space by a partition member having a hole through which urine passes. The excrement disposal material 1 is laid in the upper space (on the partition member) of the system toilet.

  The granular material 10 is a granulated product of pulverized material including a laminate material. The granular material 10 is mainly made of a laminate material. Here, the main material means a material having the largest weight ratio in the granular material 10 among the materials constituting the granular material 10. The pulverized material may include only the laminate material, or may include the laminate material and other materials. The former means that the granular material 10 consists only of a laminate material. The weight ratio of the laminate material to the granular material 10 is preferably 90% or more. As materials other than the laminate material, for example, papers, tea husks and the like can be used.

  FIG. 2 is a side view showing a laminate material constituting the granular material 10. The laminate material 20 includes a layer 22 (first layer) and a layer 24 (second layer) laminated on the layer 22. The layer 22 may be made of a hydrophilic material such as paper, or may be made of a hydrophobic material. The layer 24 is made of a hydrophobic material. The layer 22 is preferably made of a material having a higher melting point than the hydrophobic material constituting the layer 24. In the granular material 10, at least a part of the hydrophobic material that has flowed out of the layer 24 enters the gap between the pulverized materials.

  As the laminate material 20, for example, photographic paper, release paper, an aluminum vapor deposition film, or the like can be used. Moreover, as a hydrophobic material which comprises the layer 24, a plastics, paraffin, or wax is mentioned, for example.

  Then, an example of the manufacturing method of the excrement disposal material 1 is demonstrated as one Embodiment of the manufacturing method of the excrement disposal material by this invention. This manufacturing method includes a preparation step and a granule forming step.

  The preparation step is a step of preparing a pulverized material including the laminate material 20. In this step, the pulverized material including the laminate material 20 is prepared by pulverizing the laminate material (and materials other than the laminate material) using a pulverizer.

  The granule forming step is a step of forming the granule 10 by granulating the pulverized material prepared in the preparation step. In this step, the pulverized material is granulated using an extrusion granulator. Prior to granulation, the pulverized material is subjected to pretreatment such as kneading and adding water as necessary.

  In the granule forming step, at least a part of the hydrophobic material constituting the layer 24 of the laminate material 20 is dissolved. For example, the hydrophobic material may be dissolved by raising the temperature of the pulverized material above the melting point of the hydrophobic material in an extrusion granulator. Thereby, the pulverized material is granulated in a state where the hydrophobic material is dissolved. The dissolved hydrophobic material flows out of the layer 24 as shown in FIG. 3, and enters the gap between the pulverized materials. Thereafter, when the temperature of the pulverized material is lowered, the hydrophobic material that has entered the gap is re-solidified.

  In the present embodiment, the pulverized material is heated by heating the pulverized material. As a means for heating the pulverized material, for example, a die of an extrusion granulator is heated to a high temperature, or granulation is performed in a high temperature atmosphere. Thereafter, post-treatments such as sieving (sizing) and drying are performed as necessary. Thus, the excrement disposal material 1 made of the granular material 10 is obtained.

  The effect of this embodiment will be described. In the present embodiment, the granular material 10 is formed by granulating a pulverized material including the laminate material 20. In the granule forming step, at least a part of the hydrophobic material constituting the layer 24 of the laminate material 20 is dissolved. The dissolved hydrophobic material flows out of the layer 24 and enters the gap between the pulverized materials. Thereby, in the excrement disposal material 1, since the said clearance gap is block | closed with a hydrophobic material, it becomes difficult for a water | moisture content to permeate the inside of the granular material 10. FIG. For this reason, the granular material 10 having water repellency can be obtained without performing water repellency treatment. Therefore, the excrement disposal material 1 that can exhibit water repellency even if the water repellency treatment is omitted, and a method for manufacturing the same are realized. Actually, in this embodiment, the water repellent treatment is not performed on the granular material 10.

  The granular material 10 is formed by granulating a pulverized material using an extrusion granulator. Thereby, the some granular material 10 can be formed simultaneously. However, when an extrusion granulator is used in this way, it is normal that a gap serving as a moisture intrusion path is generated inside the granule. Therefore, in this case, the present embodiment in which such a gap can be filled with a hydrophobic material is particularly useful.

  The granulation of the pulverized material is performed in a state where the hydrophobic material of the layer 24 is dissolved. Thus, by dissolving a hydrophobic material at the time of granulation, the dissolved hydrophobic material can be spread over a wide range. This is advantageous for evenly filling the gaps between the pulverized materials with the hydrophobic material.

  The granular material 10 has a laminate material 20 as a main material. Thereby, compared with the case where the laminate material 20 is not the main material of the granular material 10, the gaps between the pulverized materials are closed by more hydrophobic material, so that the water repellency of the granular material 10 can be increased. Thus, from the viewpoint of increasing the water repellency of the granular material 10, the weight ratio of the laminate material 20 in the granular material 10 is preferably 90% or more, and the granular material 10 is particularly preferably composed of only the laminate material 20.

  When the hydrophobic material constituting the layer 24 of the laminate material 20 is plastic, there are many kinds of laminate materials having a plastic layer, so that there is an advantage that the selection range of the laminate material 20 is widened. On the other hand, when the hydrophobic material is paraffin or wax, since the dissolved paraffin or wax has high fluidity, there is an advantage that the hydrophobic material is easily spread over a wide range.

  Even when the layer 22 of the laminate material 20 is made of a hydrophilic material, the hydrophobic material dissolved as described above enters the gaps between the pulverized materials, so that the granular material 10 having water repellency is obtained. Thus, since the thing which has a layer which consists of a hydrophilic material as the laminate material 20 can also be used, the breadth of selection of the laminate material 20 spreads.

  When the layer 22 is made of a material having a melting point higher than that of the hydrophobic material constituting the layer 24, the hydrophobic material constituting the layer 24 can be dissolved without dissolving the material constituting the layer 22. Thus, it becomes easy to hold | maintain the shape of the granular material 10 by dissolving only the hydrophobic material which comprises the layer 24. FIG.

  The present invention is not limited to the above embodiment, and various modifications can be made. In the said embodiment, the case where the laminate material 20 was the main material of the granular material 10 was illustrated. However, the granular material 10 may be made of a material other than the laminate material 20 as a main material.

  In the said embodiment, the case where a ground material was heated up more than melting | fusing point of a hydrophobic material by heating the ground material was illustrated. However, the pulverized material may be heated by natural heat generation during granulation without heating the pulverized material.

  In the said embodiment, the case where the hydrophobic material was dissolved at the time of granulation was illustrated. However, in the granule forming step, the hydrophobic material may be dissolved after granulation. For example, the hydrophobic material can be dissolved by heating the granulated material (granulate 10) after granulation to raise the temperature to the melting point of the hydrophobic material or higher.

  In the said embodiment, the case where materials, such as the laminate material 20, were grind | pulverized in the preparation process, was illustrated. However, in the preparation step, a material such as a laminate material 20 that has been crushed in advance may be procured.
