In the present invention, the waste wood pulverized product of the core portion mainly contains fibrous waste wood particles having a particle size of 5 mm or less, preferably 3 mm or less, and more preferably 2 mm or less. In the coating layer portion, the pulverized waste wood pulverized can be easily coated by making it finer to have a particle size of, for example, 0.5 mm or less. It is preferable to use a fiberized waste wood crushed product mainly containing waste wood particles. Since fine fine particles are easily peeled off during storage, the pulverized waste wood pulverized product of the coating layer portion has a particle size of 0.1 to 0.5 mm, preferably a waste product containing fibrous waste wood particles. Preference is given to crushed wood. 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, waste wood is pruned branches, bark of wood, used building materials from construction sites of wood, wood pieces and wood chips generated from sawmills, and sawdust, etc. It is crushed to size.
The crushed waste wood pieces are subjected to electrostatic separation and magnetic separation in order to separate those having metal. Iron pieces and / or metal pieces separated by electrostatic separation and magnetic separation 50 to 3
A piece of waste wood with a size of 00 mm is coarsely crushed into particles with a size of 5 to 30 mm. For the coarsely crushed waste wood grains,
Since a certain amount of metal particles are contaminated, the metal particles to be contaminated are separated by wind separation (air elutriation) or magnetic separation (magnetic separation), and the waste wood particles separated from the metal particles are separated by a defibrator. Three
Fiberized to a particle size of ˜5 mm. In the present invention, the pulverized waste wood pulverized product contains fibrous particles and is excellent in water absorption and water retention as compared with the pulverized waste wood pulverized product which is not fibrillated. Here, in the fibrous particles, the length of the long axis of the particle, that is, the length of the particle with respect to the width 1 of the particle, that is, the width 1 of the particle, is 4 or more, and preferably 6 or more. In the present invention, the fibrous pulverized waste wood contains 50% by weight of fibrous particles having such a size ratio.
The above content is preferably 70% by weight or more.

In the present invention, the 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 super absorbent resin and water and extrusion granulated. It is difficult to granulate the pulverized waste wood that is not fibrillated into granules even as a mixture with the superabsorbent resin.
In the present invention, the use of the super absorbent polymer can be reduced by fiberizing the wood powder. In the present invention, the amount of the highly water-absorbent resin used is sufficient to maintain the water absorbing ability, the water retaining ability, and the adhering ability of the wet granulated particles to each other as the excrement treating material. In order to facilitate the adhesion of the granulated particles to each other and the adhesion of the fibrous particles, a sizing agent can be used instead of the superabsorbent resin. As such a sizing agent, an adhesive agent such as polyacrylamide, α-starch, polyvinyl alcohol (PVA) or carboxymethyl cellulose (CMC) can be used. In the present invention, it is preferable to use polyacrylamide and α-starch for attaching particles in a fibrous form.

In the present invention, a mixture obtained by mixing the fibrous particles of the pulverized waste wood pulverized with the super absorbent resin and water is used for the extrusion granulation. In the case of particles of the waste wood pulverized product which are not fibrillated and are simply pulverized to a particle size of 3 to 5 mm, the content of the fibrous particles is 20% by weight or less, and the mixture is a mixture of the super absorbent polymer and water. Then, it is difficult to granulate by extrusion granulation. In the present invention, the crushed waste wood particles are fibrillated and crushed by a defibrating machine, for example, a commercially available dry paper piece defibrating machine, to form fibrous waste wood grains. The waste wood pulverized product having a particle size of 3 to 5 mm disintegrated by a disintegrator contains fibrous particles at a content of 70% by weight or more. It is preferable that the wood powder such as sawdust is defibrated by a defibrating machine and used, since the granulation work can be performed smoothly 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 mm or more, for example, 2 mm, 3 m.
m, 4 mm or 5 mm or more is produced by granulating, for example, the water content is 10% or less, preferably 5
It is stored in a dry state of not more than%. In the present invention, the granular animal excrement disposal material can prevent the development of mold during storage by drying it so that the water content is 15% by weight or less, preferably 10% by weight. ,
When granulating with a water content of 20% by weight or more, it is preferable to dry at the final stage until the water content of 10% by weight or less.

In the present invention, as the waste wood generated from construction sites and sawmills, any of the coniferous wood and the hardwood can be used. In the present invention, the waste wood used as the animal excrement disposal material is preferably waste wood containing hinokitiol as a component in order to avoid the generation of mold during storage. Hinoki thiol is contained in the wood of the cypress family, and such woods of the cypress family include, for example, Asunaro and Hinoki Asunaro (Hiba) in the genus Asunaro.
There are, as woods of the genus Murida, Ibuki and Heine, woods of the genus Kurobe include kurobe (mouse) and Western Red Cedar, and in the genus Incense, there are Incense Cedar, which is the genus Cypress. There is Taiwan cypress.

In the present invention, the excrement disposal material gives the animal a dry and silky feel when used, and
In order to prevent the generation of mold etc. when storing excrement disposal materials,
It is stored dry. In the present invention, the granulated product of the waste wood crushed material used as the excrement disposal material is stored in a dried state. Therefore, in the present invention, the granulated product of the colored fibrous waste wood pulverized product is dried until the water content is preferably 10% by weight or less, more preferably 5% by weight or less, and It is used as an 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 mixed with the fibrous wood powder to granulate a waste wood pulverized product, it will take a long time. Further, it is preferable since it can be stored as an animal excrement disposal material while avoiding the generation of mold and the like. However, as the pulverized waste wood pulverized material, when using a slag obtained by collecting hinokitiol as waste wood, hinokitiol remains in the waste wood pulverized material to a small extent, so depending on the residual amount, The use of substances having a bactericidal action can be reduced or omitted.

In the present invention, the surface of the granulated product of the pulverized waste wood pulverized product has the original color of the pulverized waste wood product, and the granulated product is used as a container for treating the excrement. However, it can be specially colored with a coloring substance, and the original color of the granulated product of the pulverized waste wood can be hidden with the coloring substance to provide an excrement disposal material of various colors. In the present invention, the colored wood powder granules can be used as a masking material and excrement disposal material, but in this case, in order to avoid becoming dust, for example, fine particles having a particle size smaller than 1 mm are used. It is preferable to separate the powdery portion.

In the present invention, the wood powder granules are colored with a coloring substance for the purpose of matching the excrement disposal material with the use atmosphere. In the present invention, the coloring substance may be a pigment or a dye. Such pigments and dyes include, for example, white ones such as calcium carbonate, titanium oxide and synthetic pearls, blue pigments and dyes include cyanine blue, azo blue and patent blue, and green pigments and dyes. Include cyanine green and emerald green, and yellow pigments and dyes include azo yellow, acid yellow and Hansa yellow.

In the present invention, in the excrement disposal material particles, the parts in contact with urine adhere to each other to form an aggregate,
It is possible to make it easy to take out the part that comes into contact with urine. In this case, in addition to the superabsorbent resin to be mixed, polyacrylamide and / or α is included in the pulverized waste wood that has been made into fibers.
-Starch can be included. However, in addition to these, it is possible to select a material having an adhesive function of easily contacting urine and adhering the powder particles to each other to form a lump. Further, in the present invention, in order to avoid pulverization of the excrement-treating material at the time of use, it is preferable to add a substance having an adhesive function to the pulverized waste wood. Examples of the substance having such an adhesive function include polyvinyl alcohol (PVA), wheat flour, starch, and water-soluble or water-dispersible substances.
Corn starch, carboxymethyl cellulose (CM
C), pullulan, gelatin and the like, which can be used alone or as a blended substance by mixing two or more kinds thereof. In addition, alcohol-soluble compounding substances include hydroxyethyl cellulose (HEC) and hydroxypropyl cellulose (HPC).
Alternatively, polyvinylpyrrolidone or (PVP) may be used, and in this case as well, these may be used alone or as a mixture of two or more thereof.

In the excrement-treating material of the present invention, the highly water-absorbent resin is blended in order to enhance the water-absorption function, the water-retaining function and the adhesion function of particles after use of the excrement-treating material for animals. Preferably the amount is less than or equal to 30 weight percent. In the present invention, the mixing ratio of the super absorbent polymer in the excrement disposal material for animals is 5 to 30% by weight. When the adhesive function is performed by the adhesive, the amount of the super absorbent polymer is 5% by weight. It can be less than or equal to a percentage. 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 powder into fibers, it becomes easy to use such a water-absorbing resin that is not a highly water-absorbing resin. The superabsorbent resin to be blended in the present invention is generally a resin capable of retaining its shape even when absorbing several tens to 2,000 times its own weight of water, such as vinyl ester and ethylenically unsaturated carboxylic acid. Saponified copolymer of acid or its derivative, graft polymer of starch and acrylic acid, crosslinked product of polyacrylic acid, copolymer of vinyl alcohol and acrylic acid, partial hydrolyzate of polyacrylonitrile, crosslinked of carboxymethyl cellulose , Cross-linked polyethylene glycol, chitosan salt or pullulan gel, etc., and these can be blended alone or as a mixture of two or more kinds in the pulverized waste wood fiber.

In the present invention, the excrement treating material can also be used as an excrement indicator. In this case, if the colors of the coloring substance and the compounded substance are all white, for example, it will be easier to check the color development of the indicator, and it will be easy to check the animal's excrement by mixing an appropriate excretion test indicator. This is preferable because it can be carried out. The urine test indicator for animals used in the present invention is, like the conventional urine test indicators for animals, a human urine test indicator, that is, a urine pH indicator, a urine protein indicator, a urine sugar indicator, and urine hemoglobin. Indicators and other human urinalysis indicators can be used.

In the present invention, when the surface of the granulated dry particles of the waste wood pulverized product is colored white for the purpose of blending such an indicator for urinalysis, white or no indicator is added. A substantially white coloring material can be added to the fibrous waste wood pulverized product. In this case, a white or substantially white substance can be used instead of the white pigment and dye. Thus, for example, white substances such as those listed above, for example, mineral substances such as bentonite, zeolites, calcium carbonate and gypsum, and white substances such as flour and CMC, make the surface of the fibrous ground waste wood particles white. It can be used as a coloring substance. In the case of urine pH indicator, the coloring substance used is pH
Will not be affected. For example, titanium white or the like can be used.

Further, in the present invention, since the dried granulated product of the fibrous pulverized waste wood itself does not have a deodorizing ability, urine excreted by the animal is decomposed into a dirty odor. In order to avoid it as much as possible, the animal excrement disposal material of the present invention, as an auxiliary deodorant, in an amount of 10% by weight or less, a coffee liquid extraction residue, bentonite or zeolite having an adsorbing ability, in the present invention, a fibrous It can be used in an amount of 10% by weight or less as a main component of the animal excrement disposal material together with the waste wood pulverized product. In the present invention, in order to avoid pulverization of the excrement-treating material at the time of use, it is preferable to add a substance having an adhesive function to the pulverized waste wood pulverized product.

In the present invention, the excrement treating material has a particle size of 1 mm or more (eg
It is preferable to granulate the granules on a 1 mm sieve), but 2
Granulation into particles having a particle size of mm or more makes it difficult to disperse into a room, for example, from a box for animal toilets, and even if the particles disperse temporarily, it is easy to collect the particles, which is preferable in maintaining indoor hygiene. However, in these cases, the existence of particles having a particle size of 1 mm or less and the existence of particles having a particle size of 2 mm or less are not completely excluded. Granules are spherical, columnar,
It can be formed into various shapes such as a granular shape and a granular shape.

In the present invention, the mixture of the pulverized waste wood and the superabsorbent resin is granulated by a granulator. As the granulating apparatus, a conventionally well-known extrusion granulating apparatus can be used. However, other than this, various granulating devices such as a pan type, a drum type, a fluidized bed type, and a tablet molding machine can be used. In these granulators, the adherence of a coloring substance such as white powder to the surface of the granulated granulated product is such that when the granulated product is formed, for example, the white powder is directly contacted with the granulated product surface. It can be carried out by adhering it, or by making a white powder into a solution or suspension and adhering it by spraying or the like.

In the present invention, the surfactant is applied in order to improve the wetting of the plastic coating covering the surface of the waste wood and to increase the water absorption rate of the granulated product of the waste wood pulverized product. And cationic, nonionic or anionic, anionic or zwitterionic surfactants can be used. Examples of anionic surfactants include dodecylbenzene sulfonic acid and sulfosuccinic acid type anionic surfactants, and examples of nonionic surfactants include octyl phenyl ether and polyoxyethylene derivatives, and cations. Examples of the surfactant include lauryl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, and coconut amine acetate.

In the present invention, a pulverized waste wood pulverized product, a mixture of superabsorbent resin and water is granulated.
