Description

DETAILED DESCRIPTION OF THE INVENTION (1) Object of the Invention [Field of Industrial Application] The present invention relates to a defecation bed material for animals kept indoors, so-called pets.

Here, the defecation laying material includes not only toilet bowls for domestic animals but also those laid on the bottom of cages (birdhouses) or cages for domestic animals.

The breeding animals are mainly cats and dogs, which are often bred as pets in general, but the litter according to the present invention can also be used for other breeding animals.

[Conventional technology]

Conventionally, sand has been generally used as this kind of flooring material, but when entering or leaving a breeding box, toilet bowl, etc., there is a disadvantage that sand containing excrement is scattered outside the breeding box, toilet bowl, etc. It was Therefore, recently, it has been proposed to use a granular clay mineral that agglomerates due to water absorption such as bentonite to prevent the above scattering and to facilitate the treatment work after use. Further, an adsorption type deodorant such as zeolite is used alone or mixed with sand or the like in order to remove a bad odor released from animal excrement.

However, a mixture of a clay mineral and a chemical deodorant other than the adsorption type, as in the present invention described below, has not yet been known.

[Problems to be solved by the invention]

According to the study of the present inventor, when a clay mineral such as bentonite is mixed with an adsorption type deodorizing agent such as zeolite, a sufficient deodorizing effect cannot be obtained due to leakage due to excreted liquid (urine), On the other hand, it was found that when a water-soluble chemical deodorant was mixed, the deodorizing property was obtained, but the water retention capacity and agglomeration of the clay mineral decreased. This is because when a clay mineral is added with an aqueous solution other than neutral, its water retention capacity and agglomeration are weakened. When it drops that way,
It becomes a "sticky" mud. By the way, urine is
This is not the case in the initial state of excretion, since it is almost neutral.

Therefore, an object of the present invention is to provide a flooring material that can sufficiently exert the deodorizing effect without inhibiting the water retention ability and the agglomeration of the clay mineral based on the above findings.

(2) Configuration of the invention [Means for solving the problems] In order to solve the above problems and to achieve the above object, the gist of the means of the present invention is to provide a granular clayey mineral with a chemical deodorant. In the defecation laying material for domestic animals, which comprises a solid organic acid or a salt thereof as the chemical deodorant, the deodorizing bed material is supported in at least the pores of the granular porous material. Exists in bedding.

In a preferred embodiment of the present invention, as the chemical deodorant, an organic acid or a salt thereof, particularly oxalic acid, citric acid,
At least 0.02% by weight of malic acid, gluconic acid and their salts are used, 3-40% by weight of zeolite and pumice alone or as a mixture is used as the porous substance, and bentonite is used as the clay mineral. To be done. The particle size of the clay mineral and the porous material is 0.5 to 10 mm, and the particle size ratio is 1: 2.
~ 2: 1 is used.

Examples of the granular clay mineral that is a component of the present invention include bentonite and kaolinite. Bentonite is preferable, but not particularly limited. This is preferably used after crushing the clay minerals, sieving to obtain the particles of the required particle size with a sieving device, and appropriately drying.

As the granular porous material which is another component of the present invention, zeolite or pumice is used alone or as a mixture, and those having relatively large pore diameter and pore volume are preferable. As a particularly preferred porous substance, the adsorption effect decreases when it is wet with urine, but considering that it still has some adsorption effect, and that a relatively large pore diameter / pore volume can be obtained, zeolite Is mentioned. As the zeolite, natural clinoptite or mordenite type zeolite and various synthetic types can be preferably used. The exchangeable cation (Na, Ca, etc.) contained in the zeolite is not particularly limited.

Since these zeolites are commercially available, they can be easily obtained. Of these, synthetic zeolites (Y type, 13x type, etc.) with large pore diameter and volume are used, considering the quality and the surface of chemical deodorant to be described later, and if the cost may be somewhat higher. can do. The content of zeolite in the flooring material is preferably 3 to 40% by weight,
If it is less than 3% by weight, it is impossible to evenly mix and disperse a predetermined amount in the clay mineral in a state where the chemical deodorant described later is supported, so the deodorizing effect cannot be obtained, and more than 40% by weight is not necessary. In addition, when the content is too large, the content of the clay mineral decreases, and thus the agglomeration of the mineral decreases.

The particle size of the clay mineral and the porous material is 0.5-10 m
m, preferably 2 to 7 mm. The particle size ratio of these is preferably 1: 2 to 2: 1. If the particle size ratio is large, that is, if it is out of the above range, not only homogeneous mixing cannot be obtained, but also the agglomeration of the flooring material is reduced.

As the solid chemical deodorant (or deodorant, hereinafter simply referred to as chemical deodorant), which is another component of the present invention, there are various kinds, and only the performance as a flooring material is considered. Then, a water-insoluble or poorly water-soluble organic acid or a salt thereof is preferable, but in view of the supporting treatment surface for the porous substance, etc., a water-soluble organic acid, a salt thereof, particularly oxalic acid, citric acid, malic acid, At least one of these salts such as gluconic acid is preferred. By the way, here, with chemical deodorant, its components chemically contact with urine,
It has the property of suppressing or eliminating odor.

The chemical deodorant is supported on the pores or the surface of the porous substance. In order to carry it in this manner, the chemical deodorant may be dissolved in water or / and a highly volatile solution such as ethyl alcohol, and sprayed on the porous material to dry it. The content of the chemical deodorant thus carried in the floor covering is 0.02 to 1.5% by weight,
Particularly, 0.05 to 1% by weight is preferable, and 0.02% by weight
If the amount is less than 1.5% by weight, the effect is not increased even if the amount is more than 1.5% by weight, and the effect is not increased, and since it is an acid or a salt thereof, water retention and agglomeration of the clay mineral are reduced. .

In the present invention, when zeolite is used as the porous substance, it is needless to say that it does not have to be a pure substance as long as it has at least the main component. This is because natural zeolite may contain a small amount of other components depending on the purification method, but it does not hinder the achievement of the intended purpose of the present invention.

〔Example〕

 As shown in the table below.

After dissolving oxalic acid in water and spraying this solution so that it is evenly distributed over the entire zeolite,
It was dried. Then, the oxalic acid-supporting zeolite was mixed with bentonite with stirring to obtain a flooring material. In addition,
It was observed by a microscope that oxalic acid also invaded and adhered to the pores of the zeolite.

The evaluation tests in the above table are as follows.

0.1% ammonia water was poured into 100 g of the flooring material, which was placed in a glass bottle of 5 and sealed and stored for 1 hour, and immediately after that time, evaluation was performed.

Evaluation of nodule state ○: Feels firm when lightly pressed with fingers.

△ means that it is hard but slightly soft.

× indicates that when the mouth of the bottle is turned down, it will fall apart.

Evaluation of deodorization (deodorization) ○ indicates that the ammonia gas concentration is less than 5 ppm and no ammonia odor is felt.

Δ: When the concentration is 5 ppm or more, a slight ammonia odor is felt, but there is no discomfort.

× indicates that there is no irritating odor.

Note that citric acid, malic acid, and gluconic acid were used in the same amounts as oxalic acid in the above table, but they were the same in the evaluation of the agglomeration state and deodorization.

(3) Effect of the invention The flooring material of the present invention has the composition as described above, and in particular, since the chemical deodorant is supported on at least the pores of the porous material, even when wet with urine, etc., Even if the chemical deodorant is water-soluble, immediate elution of the chemical deodorant is suppressed, and the elution is gradually performed according to the excretion amount of urine or the like and the contact amount. Therefore, the chemical deodorant, which is an acid or a salt thereof, is prevented from decreasing in water retention and agglomeration of the mineral by dissolving in a large amount into the clay mineral at one time by urine and the like, and the chemical deodorant is effectively used. It Moreover, when the porous substance is zeolite, even if it has a lower adsorption effect due to wetting, since it has a certain adsorption effect, the deodorizing effect increases with the effect of the chemical deodorant, and, Therefore, as compared with the case where the zeolite and the chemical deodorant are used alone, they can be used in a small amount, which is economically advantageous.
