Description

The present invention relates to a method for temporarily fixing an absorbent sheet and a double-sided anti-slip sheet used in the method.

  2. Description of the Related Art Conventionally, pet absorbent sheets (hereinafter sometimes simply referred to as pet sheets) for absorbing urine excreted by pets such as dogs and cats have become widespread. The pet urinates on the pet sheet, but since the pet sheet is light, when the pet moves, the pet sheet also moves and may not be able to urinate on the pet sheet. In addition, if the pet is moving around on the pet sheet, the pet sheet may be turned over or over, and it is necessary to set the pet sheet under the pet over and over again.

In order to solve this problem, a leisure sheet or newspaper with larger dimensions is laid under the pet sheet, or the pet sheet and newspaper are stopped with staples to make it difficult to move, but this is not sufficient. Furthermore, a non-slip sheet (Patent Document 1) in which a non-slip portion is formed by partially applying a resin such as a thermoplastic elastomer on the surface of the nonwoven fabric, and a liquid-impervious surface is formed by applying the resin to the entire back surface; An absorptive auxiliary sheet for pets (Patent Document 2), which has an absorbent layer that absorbs water, an impermeable layer underneath, and a non-slip layer that contacts the floor surface has been proposed.
In addition, blood and body fluids leak into the floor during surgery performed in hospitals apart from pets, so absorbent sheets can be placed on the floor for absorption, and water absorbent sheets can be placed in place of mats in kitchens. In some cases, it absorbs moisture and oil that splatters and prevents floor dirt.

However, although the above-mentioned pet sheet is multi-layered and expensive, the surface has urine absorbability, so it may be disposable after absorbing urine. In this case, there is a problem that it is difficult to use.
In addition, when an absorbent sheet is laid on the floor in a hospital or a kitchen and a person works on the floor, there is a problem that the absorbent sheet is slippery.

  The object of the present invention is to absorb the waste liquid that leaks on the floor using the absorbent sheet to prevent contamination, and even if a moving object such as a pet or a person gets on the absorbent sheet, the absorbent sheet moves. It is to provide an inexpensive method and its material that can be temporarily fixed so as to prevent contamination of the floor while reducing the risk of moving objects.

In view of the above-mentioned problems, the present inventors have found that the problem can be solved by laying a double-slip non-slip sheet under the absorbent sheet as a result of intensive studies, and have reached the present invention.
That is, the present invention is a method of temporarily fixing the absorbent sheet when a moving body is on the absorbent sheet that absorbs the waste liquid,
Under the absorbent sheet, a double-sided non-slip sheet having non-water absorption on both sides is laid, and the absorbent sheet does not move even when the moving body moves on the absorbent sheet. This is a method of temporarily fixing the sheet.

Furthermore, the present invention is characterized in that the moving body is a pet, and the absorbent sheet is an absorbent sheet for pets that absorbs water such as urine excreted from the pet.

Furthermore, the present invention is characterized in that the double-sided non-slip sheet has a double-sided adhesive tape affixed to a part of the surface in contact with the absorbent sheet.

Furthermore, the present invention is characterized in that the double-sided pressure-sensitive adhesive tape is a strong and weak double-sided pressure-sensitive adhesive tape having different adhesive strengths on both sides.

Moreover, this invention is a double-sided slip prevention sheet used for the method of temporarily fixing an absorptive sheet | seat, Comprising: Both surfaces have a micro uneven structure, It is a nonslip sheet characterized by the above-mentioned.

According to the present invention, even if the moving body rides on the absorbent sheet that absorbs the waste liquid, the absorbent sheet does not move, and the lower anti-slip sheet does not move. Further, since the non-slip sheet is non-water-absorbing, it does not absorb waste liquid and can be easily reused if it is washed and dried.
Moreover, if a double-sided adhesive tape is affixed to a part of the surface of the non-slip sheet, even if the moving body touches the non-slip sheet, the work of re-laying the absorbent sheet without moving can be saved.

(A) is a conceptual perspective view which shows the state by which the absorbent sheet was placed on the double-sided slip prevention sheet which concerns on one Embodiment of this invention, (b) is XY axis | shaft in (a). It is a conceptual sectional view (b) when it cut | disconnects by the perpendicular | vertical surface containing.

 Hereinafter, embodiments of the present invention will be described in detail. Note that the present invention is not limited to the following embodiments. Various modifications can be made to the following embodiments within the same and equivalent scope as the present invention.

In the present invention, the moving object refers to a moving object such as a human or a pet such as a dog or cat, but is not limited thereto.
Temporary fixation means that the absorbent sheet does not move when the moving body moves on the absorbent sheet.

The present invention is intended to prevent the absorbent sheet from moving even if the absorbent sheet is laid on a double-sided non-slip sheet that is non-water-absorbing on both sides and moves on the absorbent sheet.
The non-water-absorbing property in the double-sided anti-slip sheet means that the surface does not substantially absorb water. When the surface is non-water-absorbing, even if the surface is contaminated with waste liquid, it can be cleaned by washing or washing, and reuse becomes easy.

The anti-slip function of the double-sided anti-slip sheet is not limited as long as the absorbent sheet can be temporarily fixed when the moving body is placed on the absorbent sheet and moves. If both sides have anti-slip function, the upper absorbent sheet will not move, and the double-sided anti-slip sheet will not move from the floor below.

The double-sided anti-slip sheet is preferably made of a soft resin, and both sides preferably have a micro uneven structure. If the surface has a micro uneven structure, even if it rides through the absorbent sheet, the surface of the anti-slip sheet is relatively smooth, so that the moving body does not feel uncomfortable and can remain on it without being caught.

Examples of the fine concavo-convex structure on the surface include, for example, those produced by applying fine inorganic particles and organic particles to the surface of a soft resin sheet, and those obtained by polishing the resin surface with an abrasive such as a grindstone. Among them, those obtained by dispersing and slicing fine organic particles in a resin and those obtained by foaming and slicing a resin are particularly preferable.

By slicing a soft resin in which organic particles are dispersed or a foamed soft resin, irregularities can appear on the surface of the slice. For example, in the case of organic particles, a convex portion remaining without being sliced or a concave portion where the particles are removed is formed on the slice surface. This becomes an uneven structure and exhibits an anti-slip function. In this case, the organic particles may be hollow particles.
Further, if the resin is a foam, by slicing, a suction cup structure can be formed on the slice surface, which becomes a kind of uneven structure. A product obtained by slicing organic particles dispersed in a foam may be used.
Here, the diameter of each unevenness in the micro uneven structure is preferably 5 μm or more and 200 μm or less.

The organic particles are not particularly limited as long as they have a specific average volume particle diameter and do not melt at the temperature during the manufacturing process of the soft resin. The material may be epoxy-based crosslinked particles, urethane-based crosslinked particles, etc., but acrylic-based crosslinked particles, styrene-based crosslinked particles, and acrylic-styrene-based crosslinked particles are preferable in production.

Known polymerization for obtaining resin particles such as suspension polymerization, seed polymerization, and multi-stage seed polymerization of monomers having the above unsaturated bond, for example, monomer components including the following polyfunctional monomers: Mention may be made of crosslinked particles obtained by the method.
Examples of the polyfunctional monomer include polymerizable unsaturated carboxylic acid esters of polyhydric alcohols such as ethylene glycol diacrylate and ethylene glycol dimethacrylate; polymerizable unsaturated alcohol esters of polybasic acids such as triallyl cyanurate A monomer containing two or more α, β-unsaturated groups, such as an aromatic compound substituted with two or more vinyl groups such as diallyl terephthalate and divinylbenzene; Species or two or more can be used.
When polymerizing, a known monomer used in this field such as a carboxyl group-containing monomer such as acrylic acid, methacrylic acid, crotonic acid or maleic acid; a hydroxyl group-containing monomer such as 2-hydroxyethyl acrylate is used. One or two or more of the monomers can be used in combination.

The size of the organic particles is not limited, but the average particle size is preferably an average volume particle size of 5 μm or more and 200 μm or less, more preferably 10 μm or more and 150 μm or less. May be.
The content of the organic particles is preferably 2 to 20% by weight based on the solid content of the following soft resin. If it is 2% by weight or more, the surface has sufficient irregularities and good anti-slip properties, and if it is 20% by weight or less, physical properties such as impact resistance are not greatly lowered. Preferably, it is 2 to 12% by weight.

The soft resin is not limited to its molecular structure, the type of functional group contained, and its production method, and may be any soft resin, either a thermoplastic resin or a thermosetting resin.

Examples of soft thermoplastic resins include soft vinyl chloride resins, styrene elastomers such as styrene-butadiene block copolymers and styrene-butadiene-styrene block copolymers, and styrene-alkyl (meta ) Acrylate-acrylonitrile copolymer, graft copolymer in which vinyl monomer is graft-polymerized on composite rubber composed of polyorganosiloxane and alkyl (meth) acrylate, acrylonitrile-butadiene-styrene copolymer with high rubber content, high rubber Content Acrylonitrile-acrylate-styrene copolymer, silicone resin, acrylic modified silicone resin, low density polyethylene-methyl methacrylate graft copolymer, low density polyethylene-glycidyl methacrylate graft copolymer , Polyester-polyether block copolymer, urethane resin elastomer, ethylene-propylene copolymer, ethylene-α-olefin copolymer, acid group-containing ethylene-propylene copolymer, epoxy group-containing ethylene-propylene copolymer , Ethylene-vinyl acetate copolymer, ethylene-methyl methacrylate copolymer, amide resin elastomer and the like.

As the soft thermosetting resin, a softened curable resin can also be used. For example, urethane resin, unsaturated polyester resin, vinyl ester resin, epoxy resin, phenol resin, urea resin, melamine resin, alkyd resin, silicone resin and the like can be mentioned. The above resins can be used alone or in combination of two or more.

Of these, the lower the viscosity of the resin, the easier it is to disperse in terms of mixing organic particles. In this respect, a thermosetting resin is preferable. That is, since the raw material before manufacturing the thermosetting resin has a low viscosity, organic particles can be uniformly dispersed by blending organic particles in a part thereof and blending the resin raw material before curing. it can.
Among thermosetting resins, urethane resin is particularly preferable. Thermosetting urethane resin tends to make the sheet flexible, and it is easy to adjust the hardness of the resin, making it easy to process into a sheet.

A soft resin can be applied in the same manner when it is produced by a known production method. Further, when the thermoplastic resin is melted and the organic particles are dispersed and cooled, a thermoplastic resin in which the organic particles are dispersed can be obtained.
The urethane resin is obtained by reacting a polyol and / or polyamine with an isocyanate. The polyol, polyamine, and isocyanate are not limited as long as they are conventionally used for urethane reactions.

The production method of the urethane resin is not limited. Even if it is produced by a direct reaction between an isocyanate and a polyol, once the isocyanate group-terminated urethane prepolymer is produced, the isocyanate group-terminated urethane prepolymer is reacted with the polyol. May be.

A specific example of the method for producing the urethane resin is as follows. First, if necessary, a polyol (or polyamine) is blended with a urethanization catalyst, an antifoaming agent, a desiccant, an additive, a foam, a foaming agent, a foam stabilizer, and the like. (Including polyamine compounding liquid). At the same time, if necessary, additives and the like are blended with the isocyanate to obtain an isocyanate blended solution. Next, using a mixing device or a foaming device, the polyol compounded solution and the polyisocyanate compounded solution are rapidly mixed. The obtained liquid mixture is put into a predetermined container (mold), taken out after resinification, and a urethane resin is obtained.

In addition, when manufacturing urethane resin to improve the hardness and texture of the anti-slip sheet, various softeners, inorganic and organic reinforcing agents, fillers, and aging due to sunlight and heat are used as additives. Anti-aging agents for preventing, various oils and lubricants for improving processability, colorants such as dyes and pigments, antibacterial agents, fungicides and the like may be added.

Although the compounding quantity of the organic particle to a urethane resin is not specifically limited, It is preferable to set it as 2-20 weight part with respect to a total of 100 weight part of the raw material of a urethane resin. The organic particles are preferably blended and dispersed in a polyol and / or polyamine. In order to mix | blend organic particles uniformly, since it takes time, it is preferable to carry out in stable raw materials, such as a polyol and / or a polyamine. When the added amount of the organic particles is 2 parts by weight or more, an anti-slipping effect is recognized on the sheet, and when it is 20 parts by weight or less, mixing with the urethane resin is easy and the sheet processability is also good.

When the resin is foamed, there are a method using a foaming agent, an air loading method in which a gas such as air is mixed in advance, and a method using both in combination. Examples of foaming agents used in the production of urethane foams include water, carbon dioxide gas, hydrocarbons, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), hydrofluoroethers (HFEs), and the like. One type or two or more types of known foaming agents can be used. As a foam for slicing into a non-slip sheet, the foam density is preferably 40 to 150 kg / m ³ . It is preferable to disperse organic particles in the foam.

Next, the urethane resin obtained by cooling is sliced to a desired thickness and cut to a desired thickness to obtain an anti-slip sheet. However, the method for slicing and cutting is not particularly limited. A sheet with both sides sliced becomes a double-sided non-slip sheet.
For slicing, an apparatus for slicing rubber or the like can be applied. It can be manufactured by placing a soft resin material on a moving table or conveyor and slicing it in the horizontal direction with a horizontally rotating blade (band knife / saw).

Although the thickness of a sheet | seat is also decided by an application and there is no limitation, Preferably it is 1 mm or more and 50 mm or less. As the thickness increases, it becomes a mat shape, but the surface has a minute uneven structure, and those in contact with the surface become less slippery and have the same effect, so even if the thickness is only a mat shape, the sheet of the present invention To be included.

Depending on the slice: 1. Recesses due to holes caused by organic particles dispersed in soft resin coming off the slicing surface; 2. a recess in which organic particles remain; The organic particles are not cut, and irregularities such as convex portions remaining on the slice surface are generated. The concave portions in these minute irregularities are mainly single holes, and the convex portions are spherical and have a sucker structure. The above effect is presumed to be due to these characteristic uneven structures. Since the unevenness obtained in this manner is greatly affected by the organic particles as described above, the diameter of the unevenness on the sheet surface is preferably 5 μm or more and 200 μm or less. When the thickness is 5 μm or more, an anti-slip effect is exhibited on the sheet surface, and when the thickness is 200 μm or less, the feel to the human body is good. More preferably, the diameter of the irregularities on the sheet surface is 10 μm or more and 150 μm or less.

The reason why the anti-slip effect can be obtained is that the slice surface has a concavo-convex structure. In addition, when the soft resin is a urethane resin, it becomes more difficult to slip. In addition, the following is added. For example, if the soft resin is a urethane resin and the acrylic organic particles are dispersed in the soft resin, a convex portion of the hard acrylic resin is also generated in the soft resin, and the concave portion from which the organic particles are removed is formed of the urethane resin. Yes. Since the cut organic particles have a hard acrylic resin as a dot in a soft urethane resin, there is a possibility that a function as a stopper is generated. Since such a complex concavo-convex structure is formed, it can be presumed that the concavo-convex structure is not simple and can be widely used. When the foam is sliced, it is obvious that a concave portion is formed, but a convex portion is also formed around the foam. The concavo-convex structure by the foam produces a similar function. When the organic particles are dispersed in the foam, a concavo-convex structure in which the above concavo-convex structure is formed is generated, so that the anti-slip effect is considered to be improved.

Furthermore, it is preferable that the double-sided non-slip sheet has a double-sided pressure-sensitive adhesive tape affixed to a part of the surface in contact with the absorbent sheet. It is preferable to apply a double-sided pressure-sensitive adhesive tape to the non-slip sheet, because even if the moving body, for example, the moving body touches the anti-slip sheet without riding on the anti-slip sheet, the absorbent sheet does not move and the time for temporary fixing is widened. The position where the double-sided pressure-sensitive adhesive tape is pasted is not particularly limited, but it is preferably pasted at the four corners in order to obtain the maximum effect with the minimum amount.

Moreover, it is more preferable that the double-sided pressure-sensitive adhesive tape is a strong and weak double-sided pressure-sensitive adhesive tape having different adhesive strengths on both sides. If a strong adhesion surface is affixed to a non-slip sheet and a weak adhesion surface is affixed to an absorbent sheet, the absorbent sheet can be removed after use and a new absorbent sheet can be affixed to its adhesive tail. Conversely, if the weak adhesive surface is attached to the non-slip sheet and the strong adhesive surface is attached to the absorbent sheet, the absorbent sheet can be removed together with the adhesive tape after use. If both sides of the adhesive tape have the same strength, the adhesive tape is attached to the absorbent sheet when it is removed after use, or remains on the non-slip sheet, and the work after removal is troublesome.

The absorbent sheet in the present invention is not limited as long as it absorbs waste liquid containing water and oil, but a water absorbent sheet is preferable because it absorbs these well. Among these, a water absorbent sheet containing a water absorbent resin is particularly preferable.
The water-absorbing resin is not particularly limited, whether natural or synthetic, but is preferably inexpensive, excellent in absorbability, safety and durability, and free from the risk of spoilage.
Examples of such materials include synthetic water-absorbing resins, such as polyacrylic acid partially neutralized crosslinked products, starch-acrylic acid graft polymer neutralized products, and starch-acrylonitrile graft polymer hydrolysates. Saponified product of vinyl acetate-acrylic acid ester copolymer, crosslinked product of isobutylene-maleic anhydride copolymer, hydrolyzate of acrylonitrile copolymer or acrylamide copolymer, or crosslinked product thereof, acrylate-acrylamide copolymer Crosslinked product, polyvinyl alcohol crosslinked product, modified polyethylene oxide crosslinked product, acrylamide-2-methylpropanesulfonate copolymer crosslinked product, (meth) acryloylalkanesulfonate copolymer crosslinked product, crosslinked carboxymethylcellulose salt, cationic monomer Examples include cross-linked polymers It is. Among these, a polyacrylic acid partial neutralized product cross-linked product and a starch-acrylic acid graft polymer neutralized product are particularly preferable.

The above water-absorbent resin is obtained by drying and then pulverizing the water-containing gel-like polymer of the water-absorbent resin obtained by polymerization, and further adjusting the particle size if necessary, in the vicinity of the surface of the particles, with acid groups such as carboxyl groups and Alternatively, a surface-crosslinked water-absorbing resin may be obtained by surface-crosslinking with a crosslinking agent having at least two functional groups capable of reacting with the base.
Such a surface-crosslinked water-absorbing resin is preferable because it is excellent in absorption performance and absorption speed and not only under normal pressure but also under pressure, and the gel strength is increased. In particular, when the absorption performance under pressure is excellent, it is difficult to discharge the absorbed waste liquid even when a moving body gets on the absorbent sheet.

  As a crosslinking agent used for surface crosslinking, a polyglycidyl ether compound, a polyamine resin, an aziridine compound, and the like, which are known crosslinking agents that have been conventionally used, can be used. The amount of the crosslinking agent in the surface crosslinking can be variously changed depending on the kind of the crosslinking agent, the condition for crosslinking, the target performance, and the like.

These water-absorbing resins may be used alone or in combination of two or more. The water-absorbent resin may be granulated in a predetermined shape, and may be in various shapes such as irregularly crushed, spherical, scaly, fibrous, rod-like, massive, powdery, In order to improve the absorption performance of the waste liquid, it is more preferably in the form of powder.

Although there is no limitation in particular about the average particle diameter of particle | grains, Preferably it is 30-850 micrometers, More preferably, it is 60-400 micrometers. If it is larger than 30 μm, it becomes difficult for the water-absorbent resin powder to leak from the absorbent sheet, and if it is smaller than 850 μm, the absorption rate of the waste liquid is good.

The water absorbent resin preferably has an absorption ratio of water (ion exchange water) at 25 ° C. under normal pressure of 20 to 1000 times, and more preferably 80 to 600 times. When the water absorption under normal pressure is 20 times or more, the waste liquid can be sufficiently absorbed. Gels containing water with a ratio of 1000 times or less have an appropriate hardness and are difficult to leak out. The amount of water absorption can be controlled by various production conditions for the above water-absorbent resin.
The average particle diameter of the particles and the water absorption magnification can be measured by a known method for measuring water-absorbent resin.

The water-absorbing resin preferably has a low molecular weight water-soluble component, for example, a low molecular weight molecule such as an oligomer of acrylic acid. These water-soluble components give a slimy feeling when the moving body comes into contact with the water-containing gel and do not feel good. When the water-soluble component in the water-absorbent resin is 5% by weight or less, the feeling of sliminess is felt less, and the content of 1% by weight or less is more preferable because there is no feeling of slime when touched. The water-soluble component can be measured by a method such as a gravimetric method or an electrodrop method described in JP-A-2005-445.

The absorbent sheet preferably has a water-absorbing resin powder immobilized on one or both sides of a water-permeable substrate such as fabric (particularly preferably non-woven fabric) or paper, and particularly preferably paper or non-woven fabric. A water-absorbing resin is integrated by embossing method and needle punching method after sandwiching between water-permeable base materials such as embossing method; water-absorbing resin powder water is applied to one side of plastic film using adhesive or binder resin Fixed and covered with the above water-permeable substrate as it is or on one side, for example, using cellophane or vinyl adhesive tape, spraying water-absorbing resin powder on the adhesive surface and covering it directly or with a non-woven fabric or other breathable substrate. And fixed with a pressure roll. Particularly preferred is a resin in which a water-absorbing resin is sandwiched and fixed by a non-woven fabric or paper by an embossing method, and can be manufactured at low cost and has a good deodorizing effect.

The amount of the water-absorbent resin in the absorbent sheet is preferably 1.0~200g / ^{m 2,} more preferably 2.0~100g / ^{m 2.}

In the case of making an absorbent sheet, a water-insoluble water-absorbing / water-retaining material may be included together with the water-absorbent resin powder. Water-insoluble water-absorbing and water-retaining materials are those other than water-absorbing resins that swell when absorbed, such as pulp, water-absorbing fibers, coconut shells, rice straw, wood chips, wood flour, cotton, sawdust, straw, and coconut shell activated carbon. Examples thereof include inorganic water-insoluble water-absorbing / water-retaining materials and inorganic water-insoluble water-absorbing / water-holding materials such as pearlite, rock wool, porous ceramics, vermiculite, and pumice.

Moreover, it is preferable that an absorptive sheet contains at least one of a deodorizer or an antibacterial agent, since the deodorizing effect of the absorptive sheet is improved. Deodorants can deodorize odors, but antibacterial agents can suppress bacterial rot and prevent odors caused by rot. A combination of a deodorant and an antibacterial agent is preferable.

Either one side or both sides of the absorbent sheet may be absorbent, but it is preferable that only one side is water absorbent and the other side is non-absorbable. The non-absorptive surface should be formed of a water-impermeable layer such as polyethylene sheet or polypropylene sheet, and this surface does not allow waste liquid to pass through. If this surface is on the lower side, the upper absorption surface absorbs waste liquid. Even so, the double-sided anti-slip sheet on the lower side is not soiled.
The size of the absorbent sheet is not particularly limited. It is preferable to decide according to the application and the size of the non-slip sheet.

 The method of temporarily fixing the absorbent sheet of the present invention when a moving body gets on the absorbent sheet that absorbs the waste liquid, is simply laying a double-sided non-slip sheet on both sides under the absorbent sheet. Therefore, even if the moving body moves on the absorbent sheet, the absorbent sheet does not move. Therefore, even if the waste liquid leaks, the floor or the like is not soiled, and the risk of the moving body slipping is reduced.

FIG. 1 is a conceptual perspective view showing a state in which an absorbent sheet is placed on a double-sided non-slip sheet according to an embodiment of the present invention, and a vertical plane including the XY axes in (a) and (a). It is a conceptual sectional drawing (b) when cut | disconnecting by.

One non-slip sheet 2 is placed on the floor 1, and two absorbent sheets 3 are placed on the floor 1 so as to touch the center of the non-slip sheet 2 and cover the anti-slip sheet 2. In FIG. 1A, the double-sided tape 4 is shown although it is not actually visible. The double-sided tape 4 is below the absorbent sheet 3 and is attached to the four corners of the anti-slip sheet 2 and two central edges (total of six places). Although the moving body is not shown in the drawing, even if the moving body rides on the moving body, the upper surface has an anti-slip function, so that the absorbent sheet 3 does not move. Even if the anti-slip sheet 2 is soiled by a moving body or a waste liquid resulting therefrom, the anti-slip sheet 2 is non-water-absorbing and can be reused if it is taken out, washed and dried. The bottom of the double-sided anti-slip sheet 2 also has an anti-slip function, so that even if a moving body moves, it does not slide on the floor. Moreover, even if the double-sided adhesive tape 4 is affixed to the non-slip sheet 2, even if the moving body touches the non-slip sheet 2 without riding on the non-slip sheet 2, the absorbent sheet 3 does not move and the time for temporary fixing increases.

  The waste liquid in the present invention refers to a liquid that is no longer necessary and should be discarded. For example, human and pet body fluids and blood, lubricating oil that leaks to the floor from machines and equipment, waste oil such as engine oil, water and cooking oil that leaks to the floor in kitchens and kitchens, liquid seasonings, photodevelopment wastewater, paint wastewater, etc. Is mentioned. Therefore, an absorbent sheet is laid in a place where waste liquid is generated and there is a risk of leakage to prevent contamination underneath. It can be applied to a place where a moving object may be particularly placed in such a place. The method of the present invention can be suitably used in any place such as a pet residence, a hospital, a factory, a kitchen, and a kitchen.

EXAMPLES The present invention will be described below with reference to examples, but is not limited thereto.

X: The surface feels rough and feels bad.

The 30 cm × 60 cm × 2 mm non-slip sheet produced as described above is placed as shown in FIG. 1, and a 33 cm × 45 cm pet sheet (front: water absorbent sheet, back: polyethylene sheet) is placed thereon as shown in FIG. Two were placed side by side. On top of this, an 8-year-old Labrador Retriever could move freely, but the pet seat did not move. In this case, the double-sided adhesive tape is not used.

In addition, as shown in FIG. 1 above, “strong double-sided tape” (for carpet, manufactured by Nitoms Co., Ltd.) (2 cm × 5 cm) (total 2 cm × 5 cm) (6 places) Affixed strongly adhering side, affixing a pet sheet to a non-slip sheet on both sides and letting a 3 month old Labrador retriever play freely on and around it, but urine is excreted and absorbed into the pet sheet The lower side non-slip sheet was not dirty. The pet sheet was not moving. The pet touched the pet sheet from the outside of the double-sided non-slip sheet, but the pet sheet did not move.

(Comparative Example 1)
In Example 1, a sheet for pets was laid without a double-sided anti-slip sheet, and the same dog was used and allowed to play freely for half a day. The pet sheets were scattered and urine was excreted and absorbed by the pet sheets, but the floor was dirty.

(Example 2)
In the hospital, 16 sheets of the non-slip sheet used in Example 1 were spread on the floors on both sides of the operating table without gaps, and the absorbent sheet was spread with no gaps so as to cover all of them. On top of that, the operation was performed for 3 hours. During that time, there was no slipping of the absorbent sheet, and the surgeon was able to operate safely. After the operation, blood leaked underneath and the absorbent sheet was soiled, but when it was removed, the anti-slip sheet was not soiled by blood.

(Comparative Example 2)
In Example 2, only the absorbent sheet was laid without any gaps without placing the double-sided slip-proof sheet around the operating table.
