[0006] In the present invention, the animal sheets are used for excretion, like the conventional pet sheets, but are also used for rest and sleeping. In the present invention, the animal sheet has a porous layer portion, for example, a polypropylene resin, a polyethylene resin, a nylon resin, a nonwoven fabric layer portion made of a plastic fiber such as a vinylon resin, or a polyethylene resin, a polypropylene resin, a vinyl chloride resin, or the like. It can be formed with a plastic porous membrane, the lower surface is polyethylene resin,
It can be formed of a plastic impermeable film layer such as a polypropylene resin. In the present invention, a first water-absorbing paper layer may be provided below the porous layer in contact with the lower surface thereof. This water-absorbing paper layer is preferably formed of water-absorbing paper or crepe paper because good water-absorbing properties can be ensured.

In the present invention, a mixed layer portion of a highly water-absorbent resin and a water-absorbing material powder can be provided in contact with the lower surface of the water-absorbing paper layer portion. In the mixed layer portion, a so-called polymer sheet in which a highly water-absorbent resin is sandwiched between the cotton-like pulp layers and water-absorbing paper is provided on both front and back surfaces thereof can be used. When a polymer sheet is used, the water-absorbing paper layer in contact with the lower surface of the porous layer and the water-absorbing paper layer in contact with the upper surface of the water-impermeable membrane layer can be omitted. In the present invention, it is preferable to use a highly water-absorbent resin having high water absorbability, because the amount of use can be reduced. As the water-absorbing material, a crushed material of waste paper such as cottony pulp, wood flour, paper powder, and punch waste having relatively high water absorption can be used. When the pulverized material of wood flour and punch dust is added to the floc pulp, the amount of the pulverized material of wood flour and punch dust is 3 to 20% by weight or less, preferably 3 to 20% by weight of the floc pulp.
10% by weight or less. In the present invention, a water-absorbing material layer may be provided in contact with the lower surface of the mixed layer, and a second water-absorbing paper layer may be provided in contact with the lower surface of the flocculent pulp layer. it can.

In the present invention, as the insect repellent, a pyrethroid insect repellent having a transpirable contact toxic action or a pyrethroid insect repellent having a non-transpirant contact toxic action can be used. As a transpirable pyrethroid insecticide having contact poison, for example, empentrin can be used, and as a non-transpirant contact toxic pyrethroid insecticide, permethrin [3- (2,2-dichloroethenyl)- 2,2-dimethylcyclopropanecarboxylic acid (3-phenoxyphenyl) methyl ester (3-
(2,2-) Dichroethenyl) -2,
2-dimethylcyclopropanecar
boxic acid (3-phenoxyphe
nyl) methylester] can be used. Also, other pyrethroid insect repellents, for example, arethrin, phenothrin, phthalthrine, framethrin,
Resmethrin, extractin, permethrin and the like can also be used in place of the above-mentioned empentrin and permethrin, or mixed with at least one of them.

The pyrethroid insecticides permethrin and empentrin used in the present invention have a contact toxic effect and are insecticidal components, but are relatively harmless to warm-blooded animals. Is what is being done. Empentrin contacts the animal's body and acts to expel pests such as mites and fleas from the animal's body, and its structural formula is represented by the following formula.

The transpirable pyrethroid-based insecticide can be contained in the water-absorbing paper layer or the mixed layer of the superabsorbent resin and the water-absorbing material powder. In this case, the amount used for the sheet is 0.05% by weight or more, preferably 0.4% by weight, based on the weight of the sheet, in the case of any of the non-transpirable and transpirable pyrethroid-based insecticides. % Or more.
However, pyrethroid-based insect repellents are relatively expensive, and their content is preferably 1% by weight or less. Empentrin and permethrin are insecticides that have an excellent insecticidal effect on harmful insects such as moths, beetles, mites, ticks, mosquitoes, house flies and cockroaches, have no odor, and are longer than dichlorobenzene at low concentrations. The effect can last for a long time.

In the present invention, the non-transpirable pyrethroid insect repellent permethrin and the transpirable pyrethroid insect repellent empentrin are used as animal repellent components in animal sheets. In the present invention, when a transpirable pyrethroid-based insect repellent, such as empentrin, is added to animal sheets, for example, during excretion, the empentrin in the animal sheets evaporates and comes into contact with the animal at the time of excretion, The pests that adhere to the animal body can be repelled. In this case, empentrin sprays an empentrin-containing liquid onto a water-absorbing paper layer and / or a mixture layer of a superabsorbent resin and a water-absorbing material powder, or coats the paper layer and / or the mixing section with the empentrin. It can be immersed in an empentrin-containing liquid to impregnate the empentrin-containing liquid. When permethrin, a non-transpirant pyrethroid-based insecticide, is used, the water-absorbent paper layer can be impregnated with a permethrin-containing liquid by a spraying method or a dipping method.

When an animal sheet is impregnated with a transpirable or non-transpirable pyrethroid insect repellent, the insect repellent is printed on a water-absorbing paper layer with a printing ink containing the pyrethroid insect repellent. Can be impregnated.
A printing ink containing a transpirable and / or non-transpirable pyrethroid insecticide can be produced by dissolving or dispersing the pyrethroid insecticide in a pH test printing ink. In the case of other color inks, if a suitable coloring material is blended, desired patterns and characters can be printed on the printing surface, and for example, decorative patterns and patterns and characters for commercial advertisement can be printed.

In the above case, when the animal sheet is impregnated with the transpirable pyrethroid-based insecticide, for example, empentrin, which is the transpirable pyrethroid-based insect repellent in the animal sheet, evaporates, and the animal sheet is immersed in the animal sheet. And the evaporative pyrethroid-based insect repellent empentrin in the animal sheets evaporates, and the evaporated empentrin comes into contact with the animal at rest, at bedtime, or at the time of excretion. The pests adhering to the soil can be repelled.

Further, a non-transpirable pyrethroid-based insect repellent is used,
When impregnating the animal sheets, the pests that come into contact with the body hair and adhere to the animal body at the time of use can be controlled, and the pests in the animal sheets can be controlled at the time of use. further,
When impregnating the non-transpirable pyrethroid insect repellent and the transpiring pyrethroid insect repellent into animal sheets, for example, the emptolin of the transpirable pyrethroid insect repellent in the animal sheets evaporates, at rest, at bedtime At the time of excretion, at the same time as exterminating the pests in the animal sheets, at rest,
The pest which comes into contact with the animal at the time of bedtime or excretion and adheres to the animal can be repelled.

In the present invention, the animal sheet is produced by mixing a pyrethroid-based insecticide in a far smaller amount than the mixture layer of the superabsorbent resin and the water-absorbing material powder, alone or in combination with other insect repellent components. Can be. In this case, when impregnating a non-transpirable and / or transpiring pyrethroid-based insect repellent, a water-absorbing paper layer portion, or a mixture of a superabsorbent resin and a water-absorbing material powder, or a water-absorbing paper layer portion, The mixture of the superabsorbent resin and the water-absorbent material powder is immersed in the pyrethroid-based insecticide solution in which the non-transpirable pyrethroid-based insecticide and / or the transpirable pyrethroid-based insecticide is dispersed or dissolved in a solvent, or the pyrethroid is used. The pyrethroid-based insecticide solution in which the insecticide is dispersed or dissolved in a solvent can be impregnated by spraying the mixture.
Further, by printing an ink containing the pyrethroid-based insecticide solution on the water-absorbing paper layer, the pyrethroid-based insecticide can be blended into animal sheets.

In the present invention, as a repellent for other insects,
For example, powder of hiba wood and hinoki wood can be used.
Hiba wood and Hinoki wood contain hinokitiol and Hiba oil, which have insect repellent action, so that by adding waste materials such as Hiba wood chips and Hinoki wood chips together with pyrethroid-based insect repellents to animal sheets. In addition to the insect repellent action of the pyrethroid-based insect repellent, the insect repellent action of Hiba oil and / or hinokitiol can be added to increase the insect repellent action.

As described above, when hinokitiol and hiba oil-containing, for example, hiba wood chips and hinoki wood chips are used together with a pyrethroid-based insect repellent as insect repellent components, hiba wood chips and hinoki wood are used. Wood chips as it is, or a certain particle size, for example, 0.5 mm or less, preferably
It is preferable to pulverize it to 0.3 mm or less and to mix it into a mixture of a superabsorbent resin and a powder of a superabsorbent material. In the present invention, the amount of wood chips of the hiba wood and / or wood chips of the hinoki wood is not more than 20% by weight of the animal sheets. In order to maintain a high water absorption effect and strengthen the action as insect repellent,
Preferably, an amount of 3 to 10% by weight is added.

In the present invention, wood chips containing hinokitiol and / or hiba oil such as hinoki or hiba wood have deodorant properties, insect repellency and a unique aroma. Sheets can have a deodorizing function, an insect repelling function and a fragrance function. It is preferable to mix wood material of hiba wood or cypress wood with animal sheets because the insect repellent function of the animal sheets can be enhanced and the production cost can be reduced. In the present invention, activated carbon can be blended as an auxiliary deodorant in an amount of 5% by weight or less.

In the present invention, the content of the superabsorbent resin is 5 to 15% by weight or less of the animal sheet, but is preferably 7 to 12% by weight.
% By weight. In the present invention, a super-water-absorbing resin is blended in order to keep the animal sheets kept water-absorbing. The superabsorbent resin used in the present invention is preferably a resin capable of retaining its shape even when artificial urine absorbs about 30 to 100 times its own weight of water. Such superabsorbent resins include, for example, saponified copolymers of vinyl esters and ethylenically unsaturated carboxylic acids or derivatives thereof, graft polymers of starch and acrylic acid, crosslinked products of polyacrylic acid, vinyl alcohol And a polyacrylonitrile, a partially hydrolyzed product of polyacrylonitrile, a crosslinked product of carboxymethylcellulose, a crosslinked product of polyethylene glycol, a chitosan salt or a gel of pullulan. These are used alone or as a mixture of two or more of them with the water-absorbing material powder.

In the present invention, as the superabsorbent resin, for example, a superabsorbent resin-containing material recovered from waste paper diapers can be used. Such a regenerated superabsorbent resin is
The artificial urine has a water absorption capacity of 10 to 30 g / g, which is poor in water absorption performance. However, it has been found that this kind of water absorption effect can be sufficiently used in animal sheets. The particle size of the superabsorbent resin used is 50 to 500 μm.
