Description

  The present invention relates to an animal excrement disposal material composed of a water-absorbing granular material compression-molded into a granular form, for example, an excrement disposal material for pets represented by cats and dogs.

  The following Patent Document 1 discloses a technique for utilizing a coconut as a composition of the water-absorbent granular material. In this preceding example, the coconut is pulverized, in particular, the fiber layer is crushed. It is supposed to be used as a body composition.

JP 2001-95410 A

  As shown in FIG. 1, the fruit of the coconut consists of an outer shell portion 1 and an inner shell portion 2, and the outer shell portion 1 is composed of an outermost skin 3 and a fiber layer 4 covered with the outermost skin 3. 2 includes a shell 7, a pulp 8 (endosperm) covered with the shell 7, and a coconut water 9 in a cavity formed by the pulp 8. The fiber layer 4 is a layer mainly composed of insulator fibers 5 formed between the outermost skin 3 and the shell 7.

That is, the fiber layer 4 is composed of a number of insulator fibers 5 and a substance 6 (interfiber substance) made of a soft tissue existing between the insulator fibers 5.
Here, the parenchyma refers to a tissue composed of soft parenchyma that is rich in cytoplasm and has a thin cell wall.

  In Patent Document 1, the above-described coconut fiber layer 4 is peeled off from the inner shell 2, the fiber layer 4 is pulverized into short fibers, and the pulverized fiber layer is used as a composition of the water-absorbent granular material. Yes.

  Therefore, the pulverized product of the fiber layer is mainly composed of the short fibers of the insulator fiber 5 constituting the fiber layer 4 of the insulator.

The shell 7 of the inner shell portion 2 is used as a raw material of activated carbon, and the insulator fiber 5 of the fiber layer 4 of the outer shell portion 1 is hard and rich in rigidity and toughness, and is frequently used as a material such as scrubbing.
The insulator fiber 5 itself is poor in water absorption and water retention, and is therefore unsuitable as a composition for improving the water absorption ability and water retention ability, which are the original purposes of the water absorbent granular material.

  Since the fiber layer pulverized product of Patent Document 1 contains a large amount of cocoon fiber 5, the cocoon fiber 5 induces cracks and agglomerates after use (granulates together to form aggregates). There is a problem that obstructs the work of taking out the lump and replacing it with a new excrement disposal material.

In the preceding example, it is suggested that “the pulverization is performed to 2 mm or less so as not to hinder the solidification performance”, suggesting that the hard and rigid and toughness of the insulator fiber itself hinders agglomeration, and thus hinders granulation. Even if it is a short fiber of 2 mm or less, it is not a measure for effectively solving the above problems.
Also, the use of a cutting device that cuts long insulator fibers 5 which are the main constituents of the insulator fiber layers 4 into necessary short lengths is inevitably associated with high costs.

  The present invention drastically removes the coconut fibers, which are the main constituent of the coconut fiber layer, and drastically eliminates the problems of hindering the above-mentioned agglomeration and granulation by using an interfiber material composed of soft tissue. An excrement disposal material that solves the problem is provided.

  In addition, the present invention provides an excrement treatment material that improves the water absorption capacity and water retention capacity by blending the interfiber material as a water absorption material into a water absorbent granular material.

  Further, the composition of the water-absorbing granular material of Patent Document 1 is mixed with an antibacterial agent composed of essential oil (aromatic oil) to suppress spoilage that generates a strange odor after use.

  The present invention removes as much as possible the coconut fiber 5 which is the main constituent of the coconut fiber layer 4, and uses the interfiber material 6 made of soft tissue (parellate cells) as a composition of the water-absorbent granular material. In addition to improving the water absorption capacity and water retention capacity, the present invention provides an excrement treatment material capable of enhancing the odor absorption capacity of a water-absorbent granular material and effectively suppressing the generation of a strange odor.

  The present invention provides an excrement treatment material that does not contain an antibacterial agent or that requires limited mixing of the antibacterial agent, and therefore does not increase the cost of using the antibacterial agent.

  The present invention relates to an excrement treatment material comprising a water-absorbent granule that is compression-molded in a granular form, and a composition of the water-absorbent granule includes a soft tissue obtained by removing the palm fiber from a palm fiber layer. A pulverized material was included.

  The pulverized product of the interfiber material contains the cocoon fibers of the fiber layer poorly. Therefore, the pulverized product of the interfiber material containing a small amount of cocoon fibers is not prevented from forming a composition of the water-absorbent granular material.

  The pulverized material of the interfiber material composed of the soft tissue and a piece of paper, or organic fiber typified by wood pulp or waste paper pulp, or wood powder that is a cut piece of wood can be included.

  Preferably, the pulverized product of the inter-fiber material is rich in a size of 1 mm to 5 mm.

  The surface of the water-absorbing granular material can be covered with a surface layer that binds the granular materials and promotes agglomeration.

  When the surface layer is provided, the composition may contain a pulverized product of an interfiber material having a size of 1 mm or less.

  The present invention can provide an excrement disposal material that effectively solves the problems of the preceding examples.

It is explanatory drawing which outlines an example of the component of the water absorptive granular material which concerns on this invention.

  Hereinafter, the present invention will be described in detail based on a preferred embodiment shown in the drawings.

  First, the eggplant fruit will be described. As shown in FIG. 1 or 2, the eggplant fruit is composed of an outer shell portion 1 and an inner shell portion 2, and the outer shell portion 1 is composed of an outermost skin 3 and a large number of insulator fibers 5. And a substance 6 (interfiber substance) composed of a soft tissue existing between the coconut fibers 5, and the inner shell portion 2 fills the shell 7, the pulp 8 (endosperm), and the lumen of the pulp 8 coconut water 9. (FIG. 2 shows a magnification of 25 times).

  In the present invention, only the interfiber substance 6 from which the insulator fiber 5 is removed from the fiber layer 4 composed of the numerous insulator fibers 5 is extracted, and the pulverized product of the interfiber substance 6 is used as the composition of the water-absorbing granular material. It is intended to obtain excrement disposal materials for pets that are excellent in water absorption, water retention and odor absorption.

  The embodiment will be described in detail. The fiber layer 4 is sun-dried for a predetermined time and mechanically beaten to separate the fiber layer 5 into the interstitial fiber 5 and the inter-fiber substance 6, and the inter-fiber substance 6 is sieved. Then, a pulverized product of the interfiber material 6 having a size of 1 mm to 5 mm shown in FIG. 3 is obtained (FIG. 3 shows a magnification of 50 times).

  Therefore, by this, an interfiber material 6 of 5 mm or less that has passed through the mesh of the sieve is extracted, and this is used as a composition of the water-absorbing granular material.

  Preferably, an interfiber material 6 from which the highly rigid insulator fiber 5 is removed as much as possible is used as the composition of the water-absorbent granular material.

  At this time, a part of the short insulator fiber 5 is not prevented from being mixed into the pulverized material of the interfiber material 6. That is, it is important that the insulator fiber 5 is poorly blended within a range that does not inhibit the agglomeration and granulation. For example, it is preferable to keep the insulator fiber 5 to 30 or less with respect to the pulverized material 100 of the interfiber substance 6 by weight ratio.

  Further, since the inter-fiber substance 6 has a parenchyma and a multi-void structure, the step of cutting the insulator fiber 5 which is mainly made of the highly rigid insulator fiber 5 is not necessary, and the cost is low. .

  In the production of excrement disposal materials, as a composition of the water-absorbent granular material, together with the pulverized product of the interfiber material 6, paper pieces, or organic fibers represented by wood pulp or waste paper pulp, or wood flour that is a wood cut is selected. The mixed water is agitated by a shower or the like, and the stirring material is applied to a compression granulator such as a disk pelleter, so that the water absorption has a particle diameter of about φ2 mm to φ10 mm and a length of about 5 mm to 15 mm. A granular excrement treatment material rich in water absorption and water retention can be obtained by compressing and granulating the granular material, and then compressing and granulating the granulated material and drying it by applying it to a hot air dryer. In addition, this invention is not limited to this, It is also possible to carry out non-hydrolysis granulation using a tableting machine.

In the first to third blending examples of the water absorbent granular material 10 and the first and second blending examples of the surface layer 11, the bentonite blended in the first and second blending examples of the water absorbent granular material 10 is agglomerated. It is a material for promoting, and does not prevent mixing in the surface layer 11.
The vegetable adhesive material 12 is a material that promotes granulation or agglomeration of starch or / and CMC (carboxyl methylcellulose).
Further, the water-absorbing polymer 13 is a material that swells and retains about 50 to 1000 times when it absorbs water.

The organic fiber 15 includes wood pulp, waste paper pulp, straw pulp, bamboo pulp, kenaf pulp, and the like.
A piece of paper is a small piece that retains the appearance of paper as a paper.
Paper dust is a fiber produced by pulverizing paper or pulp or a pulverized product of the same.
In addition, FIG. 5 is an enlarged explanatory view outlining the excrement disposal material manufactured based on the third blending example of the water-absorbent granular material 10, and here, the bentonite is not blended.

  According to the first blending example of the surface layer 11, when the interfiber material 6 of insulator is mixed, a pulverized product of the interfiber material 6 having a size of 1 mm or less is selected.

  In addition, for the excrement disposal material covering the water-absorbent granular material 10 as a core portion with the surface layer 11, after the above-described compression granulation, again spray water or a liquid in which the adhesive is dissolved in water by a shower or the like, The compounding material of the surface layer 11 is thinly applied to the outer surface of the core part. In order to increase the spraying efficiency, the pulverized product of the interfiber material 6 to be blended in the surface layer 11 preferably has a size of 1 mm or less. In addition, the pulverized product of the interfiber material 6 having this size is advantageous in improving the initial water absorption speed.

  According to the present invention, in addition to obtaining an excrement disposal material having water absorption ability, water retention ability, and odor absorption ability, the insulator fibers 5 are removed without using the highly rigid insulator fibers 5 that require cutting. Since the inter-fiber substance 6 made of a soft tissue is used, the cutting work is not necessary, and the cost is low.

  In addition, since the inter-fiber substance 6 has a multi-void structure, it is possible to improve the void formation of the water-absorbing granular material 10 (core part) and to secure the water absorption capability essential to the water-absorbing granular material 10.

  Further, the present invention is not limited to the first to third blending examples of the water-absorbing granular material 10 and the first and second blending examples of the surface layer 11, and further blends other substances and blends antibacterial agents. It doesn't prevent it.
