In the present invention, it is preferable to add a surfactant to the core portion, the coating layer portion, or both, since the water absorbing performance can be increased. The surfactant is the same as that of the granulated material alone, and a surfactant such as a cationic surfactant, an anionic surfactant, an amphoteric ionic surfactant and a nonionic surfactant can be used. . Since a cationic surfactant has a bactericidal effect, it can be used as a substance having a bactericidal action.

In the present invention, the crushed waste wood at the core is:
It is mainly a pulverized waste wood containing fibrous waste wood particles having a particle size of 2 to 5 mm. In the present invention, the pulverized waste wood material at the core mainly contains fibrous waste wood particles having a particle size of 5 mm or less, preferably 3 mm or less, more preferably 2 mm or less. In the coating layer portion, the fibrous waste wood pulverized material can be easily coated, for example, by reducing the particle size to 0.5 mm or less, for example, fibrous particles having a particle size of 0.1 mm or less. It is preferable to use a fiberized waste wood pulverized material mainly containing waste wood particles. Since the fine particles are easily peeled off during storage, the pulverized waste wood material of the coating layer portion has a particle size of 0.1 to 0.5 mm, preferably a waste material containing fibrous waste wood particles. Pulverized wood is preferred. In the present invention, the core is
The particle size can be 2 mm or more, preferably 3 mm or more. The animal excrement disposal material can be formed to a particle size of 3 mm or more, and can be formed to a particle size of 6 mm or less.

In the present invention, fibrous particles of waste wood having a particle size of 5 mm or less, a particle size of 3 to 5 mm and a particle size of 3 mm or less are mixed with a superabsorbent resin and water and extruded and granulated. It is difficult to granulate the waste wood pulverized material that is not made into fibers, even if it is mixed with a superabsorbent resin.
In the present invention, the use of the superabsorbent resin can be reduced by fiberizing the wood flour. In the present invention, the amount of the superabsorbent resin used should be sufficient to maintain the water absorbing ability, water retaining ability, and adhesion property between wet granulated particles as an excrement disposal material. In order to facilitate the adhesion between the granulated particles and the adhesion of the fibrous particles, a paste may be used instead of the superabsorbent resin. As such a paste, an adhesive such as polyacrylamide, α-starch, polyvinyl alcohol (PVA), and carboxymethyl cellulose (CMC) can be used. In the present invention, it is preferable to use polyacrylamide and α-starch in the form of fibers for adhering particles.

In the present invention, a crushed plastic waste material containing pulp, a superabsorbent resin and a plastic substance can be used as the crushed plastic waste material. Examples of such pulverized plastic waste materials include pulverized materials of defective paper diapers, pulverized materials of defective milk pads, pulverized materials of defective urine pads, pulverized materials of defective sanitary napkins, pulverized materials of defective sanitary sheets, and production of these sanitary sheets. There are pulverized pieces of cutting waste of sanitary sheets generated at times, and in addition to these, the pulp and the superabsorbent resin contained in the pulverized material of the plastic waste material are classified and collected, and the collected residue is rich in plastic. There are pulverized materials.

Includes crushed products of plastic products and waste of used plastic products.

In the present invention, for the extrusion granulation, a mixture of fibrous particles of fibrous waste wood pulverized material, pulverized plastic waste material, superabsorbent resin and water is used. In the case of particles of waste wood pulverized material which is not fiberized and is simply pulverized to a particle size of 3 to 5 mm, the content of the fibrous particles is 20% by weight or less, and a mixture of a superabsorbent resin and water is mixed. In such a case, it is difficult to granulate into granules by extrusion granulation. In the present invention, to form fiberized waste wood particles, the crushed waste wood particles are fiberized and crushed by a defibrator, for example, a commercially available dry paper defibrator. Particle size of 3 to 5 m defibrated by defibrating machine
m contains the fibrous particles in a content of 70% by weight or more. It is preferable that wood powder such as sawdust is defibrated and used by a defibrating machine because granulation work can be smoothly performed when granulating without mixing paper materials such as paper powder. In the present invention, the granular excrement disposal material for animals has a particle size of 2 m.
It is manufactured by granulating into particles of m or more, for example, 2 mm, 3 mm, 4 mm or 5 mm or more. For example, it is stored in a dry state with a water content of 10% or less, preferably 5% or less. In the present invention, the granular animal excrement disposal material is
By drying to a moisture content of 15% by weight or less, preferably 10% by weight, the occurrence of mold during storage can be prevented. When granulating with a water content of 20% by weight or more, It is preferable to dry until the water content in the final stage becomes 10% by weight or less.

In the present invention, as the waste wood generated from a construction site and a sawmill, both coniferous and hardwood waste woods can be used. In the present invention, the waste wood used for the animal excrement disposal material is preferably a waste wood containing hinokitiol as a component in order to avoid generation of mold during storage. Hinoki thiol is contained in cypress wood, and such cypress wood includes, for example, Asunaro and Hinoki asunaro (Hiba) in the genus Asunaro.
As wood of the genus Sorbus, there are Ibuki and Heine, and as wood of the genus Kurobe, there are Kurobe (mouse) and Western Red Cedar. There is Taiwan cypress.

In the present invention, the excrement disposal material gives the animal a dry and dry feel when used,
In order to prevent the occurrence of mold, etc. when storing the excrement disposal material,
Stored in a dry state. In the present invention, the granulated material of the waste wood pulverized material and the plastic waste material pulverized material which is used as the excrement disposal material is dried and stored. Therefore, in the present invention, the granulated material of the colored fibrous waste wood pulverized material and the plastic waste material pulverized product is preferably dried until the water content becomes 10% by weight or less, more preferably 5% by weight or less. Thus, it is used as an animal excrement disposal material. However, in the case of animal excrement disposal materials used in a relatively humid atmosphere, if a substance having a bactericidal action is blended with the fibrous wood flour and / or crushed plastic waste material and granulated, a long term This is preferable because it can be stored as an animal excrement disposal material while avoiding the occurrence of mold and the like.
However, as the fibrous waste wood pulverized material, when the collected slag from which hinokitiol is collected is used as waste wood, hinokitiol slightly remains in the waste wood pulverized material. The use of the substance having a bactericidal action can be reduced or omitted.

In the present invention, the surface of the granulated waste wood pulverized material that has been fiberized has the color inherent to the waste wood pulverized material and the plastic waste material pulverized material, and the granulated material is excreted as it is. Although it can be used as a material treating material, it can be specially colored with a coloring material to hide the original color of the granulated waste wood material with the coloring material, thereby producing various colors of excrement treating material. In the present invention, the granulated material of colored wood flour can be used as it is as an excrement disposal material. In this case, in order to avoid becoming dust, for example, a fine particle having a particle size smaller than 1 mm is used. Preferably, the powdery parts are separated.

In the present invention, the granulated wood flour is colored with a coloring substance for the purpose of harmonizing the excrement disposal material with the use atmosphere. In the present invention, pigments and dyes can be used as the coloring substance. Such pigments and dyes include, for example, calcium carbonate, titanium oxide and synthetic pearl as white ones, and cyanine blue, azo blue and patent blue as blue pigments and dyes, and green pigments and dyes. Include cyanine green and emerald green, and yellow pigments and dyes include azo yellow, acid yellow and Hansa yellow.

[0021] In the present invention, the excrement disposal material particles form an aggregate by contacting the urine with each other to form an aggregate.
It is possible to make it easy to take out the part that has touched urine. In this case, in addition to the superabsorbent resin to be mixed, polyacrylamide and / or α
-Starch can be incorporated. However, in addition to these, a material having an adhesive function of easily adhering powder particles to each other by contacting urine to form a lump can be selected. Further, in the present invention, in order to avoid powdering of the excrement disposal material at the time of use, it is preferable to mix a substance having an adhesive function with the pulverized waste wood. Examples of the substance having such an adhesive function include polyvinyl alcohol (PVA), flour, starch, and water-soluble or water-dispersible substances.
Corn starch, carboxymethylcellulose (CM
C), pullulan, gelatin and the like, which can be used alone or as a mixture of two or more of them. In addition, as the alcohol-soluble compounding substances, hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC)
Or polyvinylpyrrolidone or (PVP), and in this case as well, each of them can be used alone, or two or more of them can be used in combination.

Further, in the excrement disposal material of the present invention, the superabsorbent resin is blended in order to enhance the water absorption function, water retention function, and adhesion function between particles after use of the excrement disposal material for animals. Preferably, the amount is less than 30 weight percent. In the present invention, the mixing ratio of the superabsorbent resin in the animal excrement disposal material is 5 to 30% by weight. It can be less than or equal to percent. In the present invention, the term "highly water-absorbent resin" also means a water-absorbent resin that absorbs about 30 times as much water. In the present invention,
By making the wood flour into a fiber, the use of such a water-absorbing resin that is not a highly water-absorbing resin is facilitated. In the present invention, when a plastic waste material containing a superabsorbent resin is used, the superabsorbent resin can be supplied together with the plastic waste material pulverized material. in this case,
The insufficient amount of the superabsorbent resin can be added separately. The superabsorbent resin blended in the present invention is generally a resin capable of retaining its shape even when absorbing water of several tens to 2,000 times its own weight, for example, vinyl ester and ethylenically unsaturated carboxylic acid. Saponified copolymer with acid or derivative thereof, graft polymer of starch and acrylic acid, cross-linked product of polyacrylic acid, copolymer of vinyl alcohol and acrylic acid, partially hydrolyzed product of polyacrylonitrile, cross-linked of carboxymethyl cellulose , A crosslinked product of polyethylene glycol, a gel of chitosan or a gel of pullulan, and the like, and these can be blended with the crushed waste wood material singly or as a mixture of two or more.

In the present invention, the excrement treating material can be used also as an excrement indicator. In this case, if the colors of the coloring substance and the compounding substance are set to, for example, only white, it is easy to confirm the coloring of the indicator, and an appropriate excretion test indicator is mixed to facilitate examination of animal excrement. This is preferable because it can be carried out in a short time. The urine test indicator for animals used in the present invention may be a human urine test indicator, that is, a urine pH indicator, a urine protein indicator, a urine sugar indicator, urine hemoglobin, in the same manner as a conventional animal urine test indicator. Indicators and other human urinalysis indicators can be used.

In the present invention, when the surface of the granulated and dried particles of the crushed waste wood is colored white in order to mix such an indicator for urinalysis, the white or non-added indicator is added. The substantially white colored substance can be blended into the fibrous waste wood pulverized material and / or the plastic waste pulverized material. In this case, a substance exhibiting a white color or a substantially white color can be used in place of the above-mentioned white pigment and dye. Thus, for example, the white substances of the minerals listed above, such as bentonite, zeolites, calcium carbonate and gypsum, and the white substances such as flour and CMC,
It can be used as a coloring substance for whitening the surface of the fibrous waste wood particles. In the case of urine pH indicators, the coloring substances used do not affect the pH. For example, titanium white or the like can be used.

In the present invention, the granulated dried product of fibrous waste wood and plastic waste material does not have the deodorizing ability itself, so that urine and the like excreted by animals are decomposed and contaminated. In order to minimize odor, the animal excrement disposal material of the present invention contains 10% by weight as an auxiliary deodorant.
In the following amounts, coffee liquid extraction residue, bentonite or zeolite having adsorption capacity can be used. In the present invention, together with the fibrous waste wood pulverized material, it can be used as a main component of the animal excrement disposal material in an amount of 10% by weight or less. In the present invention, in order to avoid powdering of the excrement treating material at the time of use, it is preferable to mix a substance having an adhesive function with the fiberized waste wood pulverized material.

In the present invention, the excrement disposal material has a size of 1 mm or more in order to minimize the presence of fine dust of raw materials such as raw fibrous waste wood, plastic waste, and superabsorbent resin. It is preferable to granulate into granules having a particle size (for example, on a 1 mm sieve). However, it is easy to pick up and collect particles, which is preferable in keeping indoor hygiene. However, in these cases, the presence of particles having a particle size of 1 mm or less or the presence of particles having a particle size of 2 mm or less is not completely excluded. The granulated material can be formed into various shapes such as a sphere, a column, a granule, and a granule.
