DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urine treatment material for absorbing urine of pets such as cats and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, as a urine treatment material for pets, sand or zeolite (Japanese Patent Application Laid-Open No. 57-129622) which is used alone.
No. 1), bentonite, pulp, etc. and granulated by adding water (Japanese Utility Model Publication No. 51-133885, Japanese Patent Publication No. 54)
No. 24945, Japanese Utility Model Publication No. Sho 54-17675,
Nos. 5-132753 and JP-B-3-38811) are used, but each of them lacks water-absorbing and deodorizing properties and does not have satisfactory performance. That is, the sand has no water absorption and leaves an odor. The paper is too light and generates static electricity, so pets can stick it on their feet or body and scatter them around the room. In addition, paper has low water absorption of urine, hardly clumps, and has no deodorizing property. Zeolite is excellent in deodorizing properties of ammonia, but has slightly lower water absorption. Bentonite is easy to handle because it swells and clumps with use, but lacks deodorizing properties. In addition, zeolite and bentonite do not become combustible waste and cannot be disposed of in that field.

In order to solve these problems, natural organic substances such as rice husks, peanut shells, and wood powder are mixed with a superabsorbent resin, solidified with a binder and granulated (Japanese Patent Publication No. 3-46089). ), Which absorbs urine with a highly water-absorbent resin and has a deodorizing effect with a natural organic substance. However, there is no working example of the invention, and the deodorizing effect is not specifically shown.

[0004] Further, there is a granulation of papermaking waste and a superabsorbent resin or a mixture of these and a water-soluble inorganic salt (Japanese Patent Publication No. 3-6767). It is said to improve later tackiness, but lacks deodorizing properties. Even so, it is said that the water-soluble inorganic salts can increase the specific gravity and provide a scattering prevention effect. However, when performing toilet treatment, there is a risk of causing water pollution problems. A similar product obtained by adding two types of superabsorbent resins to pulp or paper powder (Japanese Unexamined Patent Publication No. 2-265968). Gelling and viscosity increase after absorption, but lack in deodorizing properties. .

[0005] In addition, there is a method in which bentonite powder is adhered to the surface of a granular material made of paper sludge and a water-absorbing polymer for caking (Japanese Patent Publication No. 3-32967). Therefore, they adhere to each other and form agglomerates, which hinders the water absorption of papermaking sludge and degrades deodorization. A similar product is obtained by granulating a mixture of paper powder, superabsorbent resin and bentonite (Japanese Patent Laid-Open No. 1-191626).
No.).

Further, it is said that a water-absorbing polymer obtained by adding a zeolite powder to a water-absorbing polymer (Japanese Patent Application Laid-Open No. 59-179114) can provide water absorbing and deodorizing properties.
It is not easy to handle before and after use.

In addition, fibrous powders such as zeolite, bentonite and wood flour are mixed with a water-soluble sizing agent such as dextrin and granulated (JP-A-60-102128).
No.), deodorant, easy to agglomerate and easy to handle, but low in water absorption.

[0008] Further, a product containing montmorillinite as a main component and a sodium compound and a magnesium compound added thereto (Japanese Patent Publication No. 6-73419) has high water absorption and gelling properties. Low water absorption.

[0009] In addition to the above, various proposals have been made, but none of the following shows the specific effects of the examples, and therefore, the water absorbing and deodorizing properties to be possessed as a urine treatment agent are required. It is unclear whether or not agglomeration and the like are obtained in a well-balanced manner. That is, there is a combination of papermaking sludge or pulp or paper powder with wood flour, a binder, and a water absorbing agent (Japanese Patent Application Laid-Open No. 6-7051). Also, papermaking sludge and wood flour,
A mixture of zeolite, water-absorbing polymer, surfactant, fragrance, and pH indicator (Japanese Patent Application Laid-Open No. 61-202637)
There is also.

[0010] In addition, a mixture of various pulp and an inorganic filler (Japanese Patent Publication No. 3-8738) prevents scattering of particulate matter,
A pulp sludge comprising 10 to 30% by weight of calcium carbonate (JP-A-2-177833) is said to be easy to handle and deodorizable.

However, it is said that it is agglomerated after use and is easily disposed of.

A beet moss granule coated with a paper powder containing a superabsorbent polymer added thereto, and a beet moss further coated with zeolite powder, activated fly ash or activated carbon powder as a deodorizing aid. There has also been proposed one containing about 3 to 5% (Japanese Patent Laid-Open No. 8-308420). Its features are absorption of moisture and odor and shape retention after moisture absorption.However, the shape retention is actually not good, and it is troublesome to dispose of the cat. There is also a drawback that the urine treatment material after urine absorption is scattered due to the habit of kicking, and there is a practical problem.

[0013]

DISCLOSURE OF THE INVENTION The present invention is a urine treatment material for pets such as cats, which has water absorption and deodorization properties of urine, and is easy to dispose by agglomeration after water absorption, and can be disposed of as combustible waste. They don't offer anything.

[0014]

In order to solve this problem, the present inventor coated a granular inorganic porous material or a pulp sludge with a mixture of paper powder and superabsorbent resin powder as a pet urine treatment material. As a manufacturing method, a mixture of paper powder and superabsorbent resin powder was coated on a diaphragm with water added to either a granular inorganic porous material or pulp sludge, and granulation was performed. In these, the inorganic porous body is any of zeolite, perlite, pumice, akadama, Kanuma soil, and activated carbon, and the crosslinked sodium polyacrylate is most preferable as the superabsorbent resin powder. I found it.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a granular inorganic porous material or pulp sludge can be used as a core material of a urine treatment material. Examples of the granular inorganic porous material include zeolite, perlite, pumice, Akadama, and Kanuma. Earth, activated carbon, cristobalite,
Sepiolite, diatomaceous earth, and the like. Pumice also includes volcanic rock, and diatomaceous earth is used after sintering. In addition, as natural organic powder, wood flour, rice husk, peanut husks and shells can be used as the core material. These have a deodorizing property and a water absorbing property, and zeolite has a large deodorizing effect especially on ammonia. However, these have limited water absorption,
Use alone is not sufficient.

Therefore, in order to supplement the water absorption of the granular inorganic porous material and the like, the surface of the granular inorganic porous material and the pulp sludge are coated with paper powder. Paper powder has micropores, which allow urine to be absorbed by capillary action.

However, since the paper powder alone does not adhere to each other and to the surface of the granular inorganic porous material such as zeolite or the pulp sludge, the superabsorbent resin powder is interposed. Many types of superabsorbent resin powders are known, including crosslinked sodium polyacrylate and starch-sodium acrylate graft copolymers, copolymers of vinyl alcohol and acrylic acid, and as such, It has a very good water absorption capacity and has the property of absorbing a large amount of water and gelling. In particular, it has been found that crosslinked sodium polyacrylate is most suitable for the purposes of the present invention.
In order to adhere paper powder to each other and to the surface of pulp sludge and granular inorganic porous material such as zeolite, a small amount of pulp sludge is added to pulp sludge and zeolite as core material in the manufacturing process of urine treatment material. Of water must be added.

As the urine-treating material for pets of the present invention, while maintaining the balance between water absorption and deodorizing properties, the optimum use amount of relatively expensive paper powder and super-absorbent resin powder is selected, and the size is easy to handle. Into a granular material. From this viewpoint, a granular inorganic porous material such as zeolite or a pulp sludge serving as a core material having a particle size of 0.2 to 10 mm is used. Water is added to the core material in advance, but the water causes the paper powder to adhere to each other via the superabsorbent resin powder, and at the same time, causes the paper powder to adhere to the surface of the granular inorganic porous material such as zeolite or the pulp sludge. Indispensable for coating. In order to achieve this object, it has been found effective to add an appropriate amount of water to such an extent that the surface of the granular inorganic porous material such as zeolite or the pulp sludge is wetted. Paper powder or highly water-absorbent resin powder that coats a granular inorganic porous material such as zeolite or pulp sludge has a particle size of 0.5.
mm or less is suitable. Coupling of these mutual bonds and granular inorganic porous materials such as zeolite and pulp sludge,
In other words, the formation of the granular material used as urine treatment material for pets is performed by supplying a granular inorganic porous material such as zeolite as a core material or a mixture of pulp sludge, paper powder and superabsorbent resin powder to a commercially available circular vibrator. After granulation, the dried product is used.

[0019]

The present invention will be described more specifically with reference to the following examples. 100 parts by weight of zeolite having a particle size of 0.2 to 10 mm serving as a core material and impregnated with 15 parts by weight of water are supplied to one feeder of a circular vibrator.
Paper powder of 5 mm or less (KC Flock W, manufactured by Nippon Paper Industries Co., Ltd.)
-100) 16 parts by weight of 9 parts by weight of crosslinked sodium polyacrylate (Sunfresh SCL-1 manufactured by Sanyo Chemical Industries, Ltd.) having a particle size of 0.5 mm or less was added to another feeder. Supply from By moving these materials along the circumference of the circular vibrator, the cross-linked sodium polyacrylate of the superabsorbent resin powder absorbs the moisture of the zeolite and swells, and becomes sticky to the paper powder. Are adhered to zeolite while adhering to each other, and the granules are obtained and discharged while the adhesion is enhanced by vibration.
The obtained product is dried at 80 to 90 ° C. for 20 minutes to obtain a urine treating material for pets.

When the zeolite is used, the practicable mixing ratio is described as follows.
% By weight, paper powder 5 to 35% by weight, superabsorbent resin powder 3 to 3
5% by weight, and water may be used in an amount of 7 to 35% by weight of zeolite.

In the same manner as in the case of zeolite, a urine-treating material for pets having pearlite, pumice stone, Akadama, Kanuma soil, activated carbon, and pulp sludge as core materials is obtained. Table 1 shows the compounding ratios.

[0022]

[Table 1]

Table 2 shows the water absorption performance and ammonia absorption performance of the obtained urine treating material for pets. For comparison, Table 3 shows the performance of other pet urine treatment materials. Moisture absorption performance was measured by weighing 10.0 g of each sample on a watch glass, sprinkling water gradually from above with a mesipette, saturating the sample, and ending the point where water oozed around the sample. The measurements were taken with water removed.

The ammonia adsorption performance was determined by placing 200 ml of each sample in a 3 L test pack, sprinkling 10 cc of 0.5% aqueous ammonia, and measuring the residual ammonia concentration in the pack after each time with an ammonia detector tube.

[0025]

[Table 2]

[Table 3]

From the measurement results, remarkable effects are recognized on both the water absorption performance and the ammonia adsorption performance. However, when the core material is red ball, the moisture absorption performance is slightly inferior,
Ammonia adsorption performance is excellent, and activated carbon can be put to practical use although both performances are slightly inferior.

Table 4 shows the specific gravity of each of the urine treatment materials for pets in the example, and Table 5 shows the specific gravity of the comparative example. Lighter to some extent is easier to carry and is preferable in terms of transportation costs.

[Table 5]

[0029]

The pet urine treating material of the present invention has a large water absorbing capacity for urine for pets such as cats, and is easy to handle at the time of disposal because it absorbs urine and forms a lump. It is also sanitary because there is considerable. Further, since the surface portion burns, it can be discarded as combustible waste.
