Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manure disposal floor for treating manure of pets such as dogs and cats housed indoors.

[0002]

2. Description of the Related Art As a treating agent for treating pet excrement, for example, zeolite is mixed with bentonite and fibrous material powder, and a water-soluble sizing agent is added and mixed.
This is granulated or granulated (Japanese Patent Application Laid-Open No. 6-58200)
No. 0-102128), or one in which a water-absorbent polymer composite and a deodorant are enclosed between two sheets (Japanese Patent Laid-Open No. 1-1998)
No. 120234), a papermaking sludge is mixed with a highly water-absorbing / water-retaining resin such as an acrylic acid / vinyl alcohol copolymer or a sodium acrylate polymer, and bentonite is added to the mixture and mixed and stirred. Granulated and dried (Japanese Patent Laid-Open No. 2-308736 and Japanese Patent Publication No.
No. 6767)), and further known is toilet sand (JP-A-2-171126) in which a water-insoluble, water-repellent, non-toxic waterproofing agent is attached to the entire surface of the sand. Has been. Further, in Japanese Utility Model Laid-Open No. 1-142660, in order to solidify the urine of the breeding animal by absorbing the urine of the breeding animal, on the bottom surface of the excrement processing case for the breeding animal formed in a non-water-immersive state so that the urine of the breeding animal is not permeated. An excrement disposal device for domestic animals has been proposed which is provided with the water absorbing member made of the water absorbing agent.

[0003]

[Problems to be Solved by the Invention] Zeolite or bentonite blended with fibrous material powder, blended highly water-absorbing / water-retaining resin with bentonite, or treatment material having water-absorbent polymer composite enclosed between sheets Both have the advantage that they can be flushed to the toilet, but if pet urine or the like adheres to the treatment material, leaving it for a long time easily decomposes and ferments the urine, etc. Therefore, it has to be replaced frequently, which requires a lot of troublesome labor and is economically disadvantageous. On the other hand, toilet sand with a water-insoluble and water-repellent waterproofing agent attached to the surface of sand is used as a filtering material on the upper part of a double-layered toilet to remove malodorous components contained in urine. Since it impregnates or adheres to the surface of the container, it emits less odor than the above-mentioned treated materials, but since urine passes through the toilet sand and is simply received by the non-immersed container, this container Since the unpleasant odor is surely generated from the treated urine collected in (1), frequent post-treatment is required as in the above case.
In addition, the sand used for toilet sand needs to have a large number of fine pores on the surface because it is necessary to impregnate or attach the malodorous component contained in urine, and thus it must be expensive. I have a problem. In addition, a net-like frame is provided on the bottom of the non-water-immersible case, cat sand is laid on top of this frame, and absorption / dispersion / deodorant sand is provided at the bottom of the frame. Since the urine adheres to the cat sand and gives off an offensive odor, the container also has no difference from the urine processing means by the above-mentioned processing material.

In view of the above situation, the present invention makes it possible to keep the upper layer of sand in a double-layer pet manure treatment floor always dry, and to prevent urine from adhering at all. The lower layer urine absorbent absorbs urine quickly,
The object is to provide a bed for treating feces and urine of pets that does not emit an offensive odor.

[0005]

In order to achieve the above-mentioned object, a pet dung treatment bed of the present invention has a water-absorbing / water-retaining absorbent having a water-repellent sand treated with a water-absorption inhibitor as an upper layer. It is characterized in that the urine members are arranged so as not to mix in the lower layers.

More specifically, a porous member is interposed between the upper layer sand having a water repellent function and the lower layer urine absorbing member so that the sand and the urine absorbing member are not mixed with each other. It is a feature.

In the present invention, the pet excrement treatment floor has a two-layer structure of sand having a water-repellent function and a urine absorbing member, and is laid so that the two do not mix when used.

As the upper layer sand, river sand with a small amount of clay,
Crushed sand, natural sand such as land sand, or crushed products of ceramic materials such as tiles and bricks, colored sand, marble, crushed products such as granite, Bennite, and natural or synthetic zeolites can be used. The average particle size is preferably 0.01 to 10 mm, particularly preferably 0.5 to 5 mm. Such sand is an inorganic waterproofing agent such as a silane compound, a silicone resin or a silicone resin for imparting a water-repellent function, or an organic waterproofing agent such as paraffin, wax, fluororesin, SBR resin or acrylic resin. Waterproof with a water absorption inhibitor such as a waterproofing agent. Among these, it is preferable to use silane compounds such as alkylalkoxylanes and oligomers thereof from the viewpoint of adhesion to sand.

As a method of coating the sand surface with these water-absorbing and waterproofing agents, a case of using a silane compound will be specifically described as an example. In a conventional mixer for stirring powder, sand and silane compounds are used. Mixing and stirring the compound, its organic solvent solution or its aqueous emulsion. When a silane-based compound is used in the coating process, the content in the sand is 0.01 to 1
It is preferably 0% by weight, more preferably 0.01 to 1% by weight, and particularly preferably 0.05 to 0.3% by weight. If the content is less than 0.01%, it may be difficult to impart water repellency to the sand, and if it exceeds 1% by weight, the performance of the obtained sand may deteriorate. In addition, 0.1
An aqueous emulsion containing 20% by weight of silane-based compound was added to the sand, and the silane-based compound in the aqueous emulsion was adjusted to 0.
The mixing amount can be appropriately selected so as to be 01 to 10% by weight.

The sand, which has been surface-treated by mixing an aqueous emulsion containing a silane compound, is naturally dried by the sun or forcedly dried by a dryer or a kiln (temperature 50 to 1).
00 ° C.) to evaporate the water content to reduce the water content to 8% or less,
It is preferably adjusted to 3% or less before use. At that time, the step of drying the sand treated with the silane compound or the organic solvent solution of the silane compound is only the step of volatilizing the volatile substance such as the solvent, and the drying for adjusting the water content is not necessary.

The sand thus coated on the surface has no affinity for water and urine and does not get wet.
When a pet urinates on this sand, the urine quickly permeates the sand and always maintains a dry, dry state.
During the surface treatment of the sand, the sand may be attached with an antibacterial agent using a binder, or may be simply mixed with an organic or inorganic antibacterial agent. Furthermore, fungicides, preservatives, deodorants, odorants such as fragrances, biocides and the like may be mixed in the sand.

The water absorbing / water retaining urine absorbing member disposed in the lower layer is a water absorbing resin composed of a highly water absorbing / water retaining resin such as sodium acrylate polymer or acrylic acid / vinyl alcohol copolymer, or these water absorbing agents. It contains a resin and has a form that can be separated from the sand in the upper layer for easy disposal. Specifically, it is a sheet in which a water absorbent resin is sandwiched with a non-woven fabric, or a water absorbent resin is kneaded. It is a sheet or sponge, a sheet made of a water-absorbent resin, or a lump. In this case, newspaper, cloth, water-permeable sheet, or the like can be placed between the sand and the urine absorbing member. When the porous member is interposed between the sand and the urine absorbing member, powder or granules of the water absorbing resin, or powder or pellets of bentonite and the water absorbing resin can be used as the urine absorbing member. Such a water absorbent resin may be used in combination with a deodorant such as zeolite or activated carbon, if necessary.

[0013]

Since the pet excrement treatment floor of the present invention has a double structure in which sand treated with a water absorption inhibitor is provided in the upper layer and a urine absorbing member having water absorption and water retention is arranged in the lower layer so as not to be mixed, Urine excreted by a pet is absorbed by the lower layer urine absorbing member after touching the upper layer sand, but since the upper layer sand has water repellency, the urine does not adhere to the surface of the sand. There is no offensive odor due to decomposition and fermentation, and a dry, dry state is always maintained. In addition, since urine that has passed through the sand is immediately absorbed by the urine absorbing member arranged in the lower layer, there is no odor emitted from urine, and the urine absorbing member can absorb a large amount of urine, so frequent replacement is required. You don't have to.

[0014]

Embodiments of the pet excrement treatment floor of the present invention will be described below in detail with reference to the accompanying drawings. Each of the examples is a cat manure treatment floor, and the manure treatment floor 1 shown in FIG. 1 is a rectangular toilet 2 whose upper portion is partitioned by a porous member 3 such as a wire mesh or punching metal. Below the porous member 3, a dish-shaped container 4 that can be freely taken in and out is provided. 100 parts by weight of an aqueous emulsion containing 1% by weight of hexyltriethoxysilane as a silane compound was mixed and stirred on 100 parts by weight of river sand having an average particle size of about 1.0 mm on the porous member 3. The sand 5 having a water repellent function having a water content of about 5% obtained by drying was laid, and the lower dish-shaped container 4 was made of sodium acrylate polymer and had a particle size of about 2.0 mm. The member 6 is laid.

The manure processing floor 11 shown in FIG. 2 has a sheet member 14 formed by sandwiching a water absorbent member 13 of the same quality as that laid on the toilet of FIG. 1 and the water permeable sheet 15 is interposed on the upper surface of the sheet member 14
The sand 16 having the same water-repellent function as that laid on the porous member 3 is laid.

[0016]

EFFECTS OF THE INVENTION The pet excrement treatment bed of the present invention prevents the upper layer of sand having a water-repellent function treated with a water-absorption inhibitor from mixing with the lower layer of a urine-absorbing member made of a water-absorbent resin or the like. Since the urine excreted from the pet comes in contact with the upper sand, the urine excreted by the pet passes through the sand and is absorbed by the lower urine absorbing member. Since it does not get wet even if it comes into contact with it, and urine does not adhere to its surface, there is no generation of odor due to decomposition of urine or fermentation, and it is always hygienic because it keeps a dry and dry state. In addition, since urine that has passed through the sand is immediately absorbed by the lower urine absorbing member, there is almost no odor emitted from the urine, and the urine absorbing member has an extremely high water-absorbing resin or water-absorbing resin such as sodium acrylate polymer. Frequent replacement is not required by using a sheet-shaped member containing a resin. Further, since the upper layer sand and the lower layer urine absorbing member are laid so as not to mix with each other, the treatment of the lower layer urine absorbing member is extremely simple and easy, and the indoor environment protection and handling are excellent.
