Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urine-treating granule which absorbs urine from pets such as cats and puppies, solidifies and solidifies.

[0002]

2. Description of the Related Art Granular pet urination granules of the type that absorbs and solidifies the urine of pets and discards the solidified product are called cat litter and the like for cats, and are drawn to the urination area of pets. By removing and discarding only the portion solidified by urination of the packed granules, the non-solidified granule portion can be conveniently used without waste.

[0003] Conventionally, these granules are mainly composed of inorganic components such as bentonite having excellent water absorption, and there is a problem that the solidified product cannot be incinerated and discarded. In recent years, investigations have been made into granules using flammable organic substances to improve these problems, but few of the organic substances have water absorption solidification properties comparable to bentonite,
Urination treatment granules disclosed in JP-A-7-96180 and the like are known as those which improve water absorption and solidification performance by using water-soluble hydroxyalkylalkyl celluloses. Here, as a combustible organic substance, wood powder has conventionally been often used, but it is desired to use a white pulp powder having a more clean feeling.

[0004]

However, when a pulp powder is used to produce a pet urinary treatment agent in the form of granules, there is a problem that granules having satisfactory solidification properties cannot always be obtained. Therefore, the object of the present invention is to
An object of the present invention is to provide a combustible urine-treating granule using pulp powder and having suitable solidifying properties.

[0005]

Means for Solving the Problems As a result of intensive studies in view of these problems, the present inventors have prepared granules using pulp powder having a specific particle size, and mainly prepared granules of the finished granules. By controlling the apparent density to a specific range, it was found that a flammable pet urinating agent using pulp having suitable solidifying properties could be obtained, and the present invention was completed.

[0006] That is, in order to achieve the above object, the invention described in claim 1 is a urination-treated granule,
The average particle size measured by IS Z8801 sieving screen is 7
30 to 60% by weight of pulp powder of 0 to 95 μm, 30 to 50% by weight of bentonite powder, 5 to 20% by weight of water-soluble hydroxyalkylalkylcellulose, and surfactant 2
It is characterized in that it is made into a granular form having a diameter of 1 to 8 mm and contains an apparent loose density of less than 0.40.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the urine-treating granules according to the present invention, pulp powder and bentonite powder are used as water-absorbing components. The mixing ratio of pulp powder is 30 to 6
0% by weight and the bentonite powder in the range of 30 to 50% by weight. If the pulp powder or the bentonite powder exceeds this range, the flammable material may not be obtained, or sufficient water absorption and solidification may not be achieved. The pulp powder used in the present invention is JIS Z
The average particle size measured by an 8801 sieving screen is 70 to 9
5 μm. The particle size is defined as an average particle size obtained by a wire mesh specified in JIS Z8801 by, for example, a 20-minute sieving measurement using a low tap sieve machine manufactured by Kansai Net Co., Ltd. The bentonite powder used is not particularly limited, but one having an average particle size of 100 μm or less is suitable for granulation.

In the present invention, a hydroxyalkylalkyl cellulose is used. Examples of the hydroxyalkylalkylcellulose that can be used include hydroxypropylmethylcellulose, hydroxyethylmethylcellulose, hydroxyethylethylcellulose, and the like. The amount of the hydroxyalkylalkylcellulose is preferably in the range of 5 to 20% by weight. Outside this range, necessary solidification may not occur, or granulation may be difficult.

In the present invention, a surfactant is added to improve the wettability of the material. Specifically, any one that improves the wettability of the material can be used, and examples thereof include nonionic or anionic surfactants such as polyoxyethylene oleyl ester or dodecylbenzenesulfonic acid. Surfactant is 2-4% by weight
In a proportion of If the amount is less than this range, the effect is small, and if the amount exceeds this range, it is not economically advantageous.

The urine-treating granules according to the present invention are preferably produced in the form of granules having a diameter of 1 to 8 mm. Granulation is carried out by mixing the raw materials, adding an appropriate amount of water, drying the tumbling granulation or extrusion granulation, and adjusting the particle size by sieving or the like. The apparent loose density of the granules is preferably less than 0.40. The apparent loose density is defined as the volume V (cc) of the container and the weight G of the granules contained.
(G) is defined as the ratio G / V (g / cc). The apparent loose density can be measured, for example, by using a powder tester manufactured by Hosokawa Micron Co., Ltd. to store the powder that has passed through the sieve in a measuring cup. In addition, the mesh of the sieve is appropriately selected and performed according to the particle size of the granule. The granules according to the present invention are most preferably 4 mesh.

At the time of granulation, a water-soluble starch or a water-soluble polymer such as carboxymethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose or polyvinyl alcohol may be added and used as a binder.

EXAMPLES Examples and comparative examples of the present invention will be described below. Examples 1 to 4 and Comparative Examples 1 to 5 Blending materials The following blending materials were blended in the proportions shown in Table 1. (1) Pulp powder A sifted product of KC Flock manufactured by Nippon Paper Industries Co., Ltd. was used. The average particle size is as shown in Table 1 and is in accordance with JIS Z8.
It was measured with a 801 sieve using a low tap manufactured by Kansai Wire Mesh Co., Ltd. (2) Bentonite Neokunibond manufactured by Kunimine Industries Co., Ltd. was used. (3) Hydroxyalkylalkylcellulose Hydroxypropyl methylcellulose 90SH-30000 (shown as MC in Table 1) manufactured by Shin-Etsu Chemical Co., Ltd. was used. (4) Surfactant Polyethylene glycol monooleate was used.

2. Preparation Method of Granules The materials described in Table 1 were mixed for 1 minute at 500 rpm with a 20-liter super mixer mixer manufactured by Kawada Seisakusho Co., Ltd., and then described in Table 1 with respect to 100 parts by weight of the mixed materials. Of water was added in parts by weight and mixed for 3 minutes to granulate. After the granulated product was dried at 100 ° C. for 5 hours, the granules were sieved with sieves having openings of 1 mm and 8 mm to prepare granules of 1 to 2 mm. 3. Measurement of apparent loose density The apparent loose density was measured using a 4-mesh screen with a powder tester manufactured by Hosokawa Micron.

4. Test method of granules The prepared granules are placed in a 2 liter bowl, and 20 cc of 2% saline solution is poured into the granules as artificial urine for pets.
After a minute, the solidified portion was taken out, and the saline solution added to the bottom of the container did not penetrate and the solidified body was manually taken out, and was evaluated as ○. 5. Result All of Examples 1 to 4 in the compounding range of the present invention showed a good solidified state. On the other hand, in Comparative Example 1, the apparent loose density was 0.4, which is the boundary value, but the solidification state was poor. In Comparative Example 2, the average particle size of the pulp powder was small, the apparent loose density was large, and the solidification state was poor. Comparative Example 3 has a large average particle size of the pulp powder,
The solidification state was poor. In Comparative Example 4, the average particle size of the pulp powder was very large, and the solidification state was poor. In Comparative Example 5, the content of the pulp powder was too large, and the solidification state was poor. From the results of the above Comparative Examples and Examples, it is understood that, according to the present invention, urination-treated granules exhibiting a good solidified state can be obtained using pulp powder.
