[0004]

2. Description of the Related Art Conventionally, for example, floor wetness has been wiped using a cloth rag or disposable rag, or a rod rag attached with various absorbents such as rags, rags, sponges, and the like. Water-absorbent mats are placed on places that are wetted in advance with water or the like in the washroom to prevent the floor from getting wet. Also,
On the other hand, disposable sheets for humans and animals are provided with an upper water-absorbent paper layer in contact with the inside of the water-impermeable membrane, and in contact with the inside of the water-impermeable thin layer at the bottom of the sheet, to form a lower water-absorbent sheet. A paper layer portion is provided, and paper powder containing a highly water-absorbing resin is disposed between the upper and lower paper layer portions. At present, a large amount of paper products are produced and consumed.However, a large amount of cutting waste is generated in a printing stage and a bookbinding stage, etc. corresponding to each application, and the amount thereof is enormous. I have.

[0005]

However, cloth rags and stick rags are used repeatedly, and in order to be able to reuse used rags, it is necessary to rinse or remove water adhering to the rags. It is a problem that requires much labor such as squeezing out and replacing rinsing water. In addition, paper powder and a highly water-absorbent resin are used in conventional disposable sheets, and in particular, pulverized pulp is used in paper powder. However, pulverized pulp has been difficult to obtain recently and is relatively expensive, so that its use has been problematic in terms of cost. Therefore, in disposable sheets, the pulp pulverized material is reduced, and a super-water-absorbent resin is used instead of the pulp pulverized material. However, by reducing the amount of pulp pulverized material, absorbent materials such as disposable sheets using a superabsorbent resin are formed relatively thinly because of the small amount of pulp pulverized material, resulting in poor elasticity. It becomes a relatively stiff absorber, and reduction of crushed pulp is a problem for disposable diapers and the like. On the other hand, in the case of transporting marine products, the marine products are placed on straw or paper and transported, but the straw or paper is wet by thawing or the like, and the transported marine products continue to contact the wet straw or paper. That is a problem.

[0006] Further, disposable diapers and sanitary napkins are produced in large quantities and consumed in large quantities. A large amount of film cutting waste is generated.
Plastic film cutting waste has a high combustion heat of plastic materials, and its processing is considered a problem.
That process is problematic. Furthermore, at the stage of recycling used paper, since mixing of plastic materials and metal materials is a problem, it is used as a building material such as wallpaper.
For example, chemical fiber papers, inorganic fiber papers, metal fiber papers, fiber papers containing metal oxides, and plastic film waste materials are excluded and are not used as raw materials. The present invention relates to the problems related to the raw materials and reuse of absorbent articles such as conventional rags and mats, the problems related to the raw materials and elasticity of sheets, and the disposal of inorganic fiber paper, plastic film waste and paper diaper waste. It aims to solve problems.

[0007]

Means for Solving the Problems The present inventor uses a crushed material obtained by crushing waste of sanitary materials such as defective sanitary materials containing plastic material and cutting waste of sanitary materials as the absorber to thereby reduce the absorption of the absorber. That it can be used as an absorber without impairing its performance, and that the presence of plastic material increases the heat of combustion of the absorber after use, enabling self-combustion to continue, and saving fuel during incineration, The inventors have found that the use of titanium paper waste, alumina paper waste, potassium titanate paper waste, alumina / silica paper, or the like as a raw material of the absorber can impart a function of removing odors or the like to the absorber, leading to the present invention. In addition, the present invention, as a raw material of various mats or absorbers for human or animal sheets,

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, an absorber can be used as an absorber for various applications, as a direct sheet, or as a direct packaging material. A nonwoven fabric is placed, a waterproof sheet is placed on the bottom, a sheet is formed, and it can be used as a rug, for example, an animal sheet, or various sheets for rest and sleeping, etc. Can be used as mats and packaging materials.

In the present invention, a convex portion is formed on the surface of the absorber. The convex portion supports the water-permeable thin layer forming the upper surface of the sheet or the packaging material, and forms the water-permeable thin layer. To form a space for storing water under the water, whereby water remaining on the surface of the absorbent body without being absorbed in the absorbent body is formed on a water-permeable thin layer portion of a sheet or a packaging material, for example, on a nonwoven fabric. It can be made not to remain and can give the nonwoven fabric a relatively dry feel. In this case, a concave portion can be formed instead of the convex portion. In this case, the ridge-shaped ridges formed between the concave portions support the water-permeable thin layer portion. Thus, the height of the concave or convex portion such as a dent formed in the absorber, including the thickness of the absorber, is circular within the range of the thickness that can be used as the absorber, sheets, or packaging material. It may have a polygonal shape and protrude upward or downward. In this case, the mold surface of the male mold in the pair of molds of the male mold and the female mold is formed with a plurality of convex portions, and is formed at a position corresponding to the convex portion on the mold surface of the other mold. A concave portion of a corresponding shape is formed, and one surface of the absorber, for example, the upper surface, is formed with a plurality of convex portions, for example, protrusions, and the other surface of the absorber, for example, the lower surface, corresponds to the convex portion of the upper surface. Thus, a concave portion, for example, a concave portion is formed. But,
A plurality of projections, such as projections or depressions, such as depressions, can be formed on the mold surface of one of the pair of molds, and the mold surface of the other mold can be formed as a flat surface.

In the present invention, in the case of an absorber having one water-absorbing mixed layer portion, for example, 0.1 to 2.0 m
When using an absorber having a thickness of m, the height of the provided protrusions, for example, the protrusions is 0.5 to 1.5 mm, and the overall thickness of the absorber provided with the protrusions is 0.6. To 3.5 mm. Since it is preferable that the thickness of the absorber is thinner, the thickness of the absorber is preferably 0.3 to 0.9 mm, and in this case, the thickness of the entire absorber provided with a projection, for example, a projection Is preferably 0.8 to 2.4 mm. In the case of an absorber having two upper and lower water-absorbing mixed layer portions, for example, when an absorber having a thickness of 0.3 to 3.0 mm is used, the height of the provided projection, for example, the projection is 0. The thickness of the absorber provided with a convex portion, for example, a protrusion, is 0.8 to 4.5 mm. In this case, too, the thickness of the absorber is preferably smaller.
To 1.2 mm, and in this case, the thickness of the absorber provided with the protrusions, for example, the protrusions, is preferably 1.
It is preferably between 2 and 3.6 mm.

The size of each of the plurality of hole-shaped concave portions, ie, concave convex portions, or projections formed separately on the surface of the absorber is, for example, when the shape of the projection or the concave portion on a plane is circular, A chevron-shaped protrusion having a circular base with a diameter of 2 to 12 mm, preferably 4 to 8 mm, a cylinder or a diameter of 2 to 12 mm, preferably 4 to 8 mm.
To 8 mm can be a circular depression, and when the shape of the projection or depression in the plane is a square,
The length of one side is preferably 2 to 12 mm, and more preferably 4 to 8 mm, and when the shape of the projection or depression in the plane is a polygon, the shape is measured in a direction crossing the center of the projection or depression, respectively. The size of the protrusions or depressions may be 2 to 12 mm, preferably 4 to 8 mm. In any case, the height of the convex portion from the bottom surface of the absorber or the depth of the concave portion from the upper surface of the absorber is preferably equal to or greater than the thickness of the absorber at the flat portion of the absorber. When the height of the convex portion or the depth of the concave portion is formed to be equal to or greater than the thickness of the absorber, the nonwoven fabric covering the absorber is held by the convex portion or the ridge-shaped convex portion, and The liquid remaining on the non-woven fabric penetrates the non-woven fabric and stays in the space of the liquid reservoir, so that the liquid on the non-woven fabric is retained. The residence time can be shortened. Therefore, when the concave portion formed on the upper surface of the absorber surrounds the convex portion and is formed into a shape that is partially connected, the volume of the liquid storage space can be increased, and the residence time of the liquid on the nonwoven fabric can be reduced. preferable.

In the present invention, when a female mold is used for molding the upper surface and a male mold is used for molding the lower surface, the upper surface of the absorber, for example, the surface is independent. Thus, a convex portion can be formed, and a concave portion can be formed on a surface on the opposite side, for example, on a corresponding portion on the back surface. Conversely, if a female mold is used for molding the lower surface and a male mold is used for molding the upper surface, for example, an independent recess is formed on the surface, and the opposite surface, for example, the back surface The convex portion can be formed at the corresponding position. However, when a male or female mold is used for molding the upper surface and a flat mold is used for molding the lower surface, the upper surface has a plurality of independent projections or protrusions or communicate with each other. A concave portion is formed, and the lower surface can be formed flat. In the present invention,
Embossing or creping can be performed before the formation of the convex portions and the concave portions.

In the context of the present invention, the term recess means an independent recess or depression and at least partly a continuous depression or valley-like groove, and likewise a projection is an independent projection or projection and at least a part thereof. Means a continuous ridge or convex ridge. In the present invention, when an independent recess or dent is formed on one surface, for example, the front surface, surrounded by ridge-shaped continuous projections, the other surface, for example, the back surface, It can be compression molded so as to form independent projections or protrusions surrounded by groove-shaped or valley-shaped recesses, and can be formed independently on one surface, for example, the surface, surrounded by continuous valley-shaped recesses. When the formed convex portion is formed, correspondingly, compression molding is performed on the other surface, for example, the back surface so that an independent concave portion or dent surrounded by a continuous ridge-shaped convex portion or ridge can be formed. be able to. In these cases, the uneven pattern on one of the one or the other surface can be selectively used according to the purpose of use, which is preferable. Reducing the size of the recesses gives the feel of a generally continuous surface. In the present invention, the convex portion can be formed as a cylindrical, conical, prismatic or pyramid-shaped protrusion or ridge-shaped protrusion or convex ridge, whereas the concave portion is cylindrical, conical, It can be formed in a prismatic or pyramidal bottomed hole or groove.

In the present invention, the upper and lower portions of the absorber are formed of a water-absorbing paper layer in order to increase the water absorbing ability of the absorber. This water-absorbing paper layer portion is formed by laminating one or more tissue papers, thin papers such as rayon paper or composite paper, one by one, or laminating,
Alternatively, it can be formed from a water-absorbing paper formed by a plurality of thin papers that are integrated together in advance. When the number of thin papers is increased, the water absorption speed of the absorber can be increased. In this case, the thin paper can be colored with a coloring agent that forms color when wet with water or a coloring agent that reacts with water to form a color. As the water-absorbing paper, it is possible to use a composite paper having absorptivity obtained by laminating thin paper and chemical fiber paper. In the present invention, in order to increase the water retention capacity of the absorber, between the upper and lower water-absorbent paper layer portion, a plastic waste material pulverized material, a paper absorbent material pulverized material and a water-absorbing mixed layer portion containing a water-absorbent resin are included. The upper and lower water-absorbing paper layers and the water-absorptive mixed layer are provided integrally, or integrally bonded, to form an absorber having at least a convex portion on the upper surface. In the present invention, when the absorber has a function of removing odor and the like,
In the water-absorbing mixed layer portion, the inorganic fiber paper waste material such as the titanium paper waste material, the alumina paper waste material, the potassium titanate paper waste material or the alumina silica paper waste material, or the inorganic fiber paper waste material Two or more pulverized materials can be blended. Further, in the present invention, an inorganic adsorbent such as talc, zeolite or bentonite can be blended in addition to the above-mentioned pulverized inorganic fiber waste material in order to give the absorbent a function of removing odor and the like.

In the present invention, an intermediate water-absorbing paper layer may be provided between the upper and lower water-absorbing paper layers. In this case, the intermediate water-absorbing paper layer portion, like the upper and lower water-absorbing paper layer portions, can be formed of at least one sheet of thin paper excellent in water absorption, but in order to increase water absorption, A plurality of thin papers can be formed by laminating or laminating one by one, and can also be formed by a plurality of thin papers which are integrated together in advance.
The tissue paper may be colored with a color former that develops color in response to water. A water-absorbent resin-containing layer portion or a water-absorbing mixed layer portion is provided between the upper portion and the intermediate water-absorbing paper layer portion. It is sufficient that the water-absorbent resin-containing layer portion contains a water-absorbent resin, but in addition to the water-absorbent resin, it can contain a crushed plastic waste material and / or a crushed paper waste material. It can be formed by including a pulverized waste paper material and a water-absorbent resin in a different ratio from the part. Also in this case, when the absorbent has a function of removing odor and the like, the waste paper used for the water-absorbing mixed layer portion may be titanium paper waste, alumina paper waste, potassium titanate paper waste, alumina silica paper waste, or the like. Defective inorganic fiber paper or pulverized inorganic fiber paper waste can be used. As such crushed inorganic fiber paper or inorganic fiber paper waste, crushed titanium paper or waste titanium paper waste,

In the present invention, the absorbent can be used for sheets or packaging materials. When the absorbent is a sheet or a packaging material, the member forming the upper surface may be a water-permeable thin layer portion such as a dry or wet nonwoven fabric according to the purpose. The water-permeable thin layer portion can be a plastic film having pores having a size corresponding to the degree of water permeation or a wet or dry nonwoven fabric having a water-permeability function depending on the degree of water permeation. In the present invention, when the absorber is used for a sheet, the lower surface side can be formed of a water-impermeable thin layer portion such as a water-impermeable plastic film. The thus formed water-impermeable thin layer portion is provided in contact with the lower surface of the lower water-absorbing paper layer portion, and may be formed of a water-impermeable plastic film made of a plastic material such as polyethylene resin and polypropylene resin. it can. However, in the present invention, in the case of a packaging material, the thin layer portion serving as the lower surface depends on the material to be packaged,
It can be a thin layer of water permeability. In the case of a water-permeable thin layer portion, a plastic film having pores having a size corresponding to the degree of water permeation or a wet or dry nonwoven fabric having a water-permeability according to the degree of water permeation can be used. When the absorber is configured in this manner, for example, by arranging it on a floor wet with rain or the like, it is possible to automatically absorb water that wets the floor, and it is not necessary to wipe the floor wet. Can be omitted. Sheets having such a water-permeable thin layer portion can be used as rugs for vehicles, rugs for umbrella stands, rugs for toilets, rugs around toilets, etc., to prevent the floors from getting wet. . Also,

It is.

In the present invention, in order to increase the texture and elasticity of the absorber, the content of the plastic waste pulverized material used in the water-absorbing mixed layer portion is increased as compared with the content of the paper waste pulverized material. be able to. In this case, the water absorption rate of the water-absorbing mixed layer portion is reduced due to the reduced content of the crushed pulp waste material, and water remains on the surface of the absorber without being absorbed during formation. Therefore, in the present invention, a plurality of independent concave portions or concave portions that are continuous with each other are formed on the surface of the absorber, and water remaining on the surface of the absorber is flowed into the concave portions and accommodated therein. Like that. However, the water that has flowed into the concave portion remains without being absorbed by the water-absorbing mixed layer portion because the water-absorbing speed of the water-absorbing mixed layer portion is low.

Therefore, in the present invention, a surfactant is attached to at least one surface of the absorber to increase the water absorption rate of the absorber, and a water absorbing resin is mixed to absorb the water. Increases the water retention capacity and water absorption capacity of the mixed layer. As described above, by attaching the surfactant to, for example, the front surface and / or the back surface of the absorber, water accumulated in the concave portion can be promptly absorbed by the absorber. Water can be absorbed and held in the sexual mixed layer portion. In the present invention, by forming a concave portion on the surface of the absorber, the surface area in contact with water is increased, and further, by attaching a surfactant to the concave portion, the water absorption rate of the absorber is increased, whereby the absorber is formed. Water can be quickly absorbed. As the surfactant, an anionic surfactant such as sodium dodecylbenzenesulfonate is preferable, and in addition to these, a cationic surfactant such as lauryltrimethylammonium chloride and a nonionic surfactant such as octylphenyl ether are also used. is there. In the present invention, by forming a concave portion or a convex portion on the surface of the absorber and attaching a surfactant to the surface, it is possible to reduce water remaining on the surface of the absorber.

In the present invention, when the sheets are formed, the nonwoven fabric layer is formed on the surface of the absorber by supporting the nonwoven fabric layer on the projections formed on the absorber. This is preferable because the nonwoven fabric layer on the surface of the nonwoven fabric can be prevented from wetting and water seeping out from the nonwoven fabric layer. In the present invention, a water-absorbing paper layer made of thin paper is provided on the upper and lower portions of the absorber in order to increase the water absorbing capacity of the absorber and the sheets. In order to increase the water retention capacity of the absorber, between the upper and lower water-absorbent paper layers, a water-absorptive mixed layer portion including a crushed plastic waste material, a crushed paper waste material and a water-absorbing resin is provided. The water-absorbing paper layer portion and the water-absorbing mixed layer portion at the lower portion are bonded together to form an absorber.

In the present invention, the upper water-absorbing paper layer, the lower water-absorbing paper layer, and the crushed plastic waste material, the crushed paper waste material and the water-absorbent resin provided between the upper and lower paper layers are used. The water-absorptive mixed layer portion is embossed and pressure-formed into a relatively flexible plate. Such a relatively flexible plate-like body is preferable because it adheres well to the floor portion and easily absorbs water droplets and the like on the floor.
In the present invention, an intermediate water-absorbing paper layer can be provided between the upper and lower water-absorbing paper layers. When the water-absorbing paper layer is made into three layers, a water-absorbing resin-containing layer can be formed between the upper water-absorbing paper layers between the upper and intermediate water-absorbing paper layers. When only water absorbency is required and elasticity is not required, only the water absorbent resin can be arranged.However, when not only water absorbency but also elasticity is required, waste plastic powder is added to the water absorbent resin. In addition, elasticity can be provided.

In the present invention, the sheet has a water-permeable thin layer forming the upper surface. Can be formed of a porous film made of a plastic material such as polypropylene, vinyl chloride resin, etc., the lower part is a water-impermeable plastic film layer, and the plastic film And a plastic impermeable thin layer made of polypropylene or the like. In the present invention, a water-absorbing paper layer may be provided inside the water-permeable thin layer in contact with the inner surface thereof. In the present invention, it is preferable to use a water-permeable thin layer portion provided with bactericidal properties and deodorant properties, since it reduces odors caused by adhering sweat and urine during use. Further, in the present invention, when the water-impermeable membrane and the water-permeable membrane layer portion of the biodegradable plastic material and the water-absorbing mixed layer portion containing the biodegradable plastic material are used, the obtained absorbent, sheets and packaging material can be soiled. It is preferable because it can be buried and disposed. In the packaging material of the present invention, when both upper and lower surfaces are water-permeable,
Both the upper and lower surfaces can be made of a water-permeable thin layer portion such as a nonwoven fabric. In the present invention, the water permeability means the property of water permeability, for example, a certain amount of water or simulated urine in 10 seconds or less (25
ml) into a 2 cm circle is determined by the time (seconds) required for the entire amount of water or simulated urine to permeate,
The shorter the transmission time, the better the water permeability than the longer one. In the present invention, the water-permeable thin layer portion is formed, for example, by adding 25 ml of water to, for example, a nozzle of a washing bottle within 10 seconds from a nozzle having a diameter of 2 ml.
When injected into a circle of cm, it is preferable that the time for transmitting the entire amount is within 20 seconds.
That is, the shorter the water permeability, the more preferable.

In the present invention, the upper, middle and lower water-absorbing paper layers are preferably formed of thin paper such as absorbent paper, water-absorbing paper or crepe paper, since good water absorption can be ensured. Further, in the present invention, as the water-absorbing paper, composite paper produced by dispersing pulp and chemical fibers in a liquid and making paper can be used. For example, a composite paper having water absorbency or water permeability, which is obtained by laminating chemical fiber paper such as polypropylene chemical fiber paper to thin paper, can be used. In the present invention, the water-absorbing paper layer portion is provided as an upper water-absorbing paper layer portion in contact with the lower surface of the water-permeable thin layer portion, and the lower water-absorbing paper layer portion is provided with the bottom of the absorber as it is. Alternatively, the bottom surface may be formed of a thin layer made of water-impermeable plastic to reinforce the bottom surface. In this case, the lower water-absorbing paper layer portion can be provided in contact with the inner surface, that is, the upper surface of the water-impermeable plastic thin layer portion. When the bottom is formed of the impermeable plastic thin layer, it is preferable to make a hole in the plastic thin layer in order to absorb a liquid such as water from the bottom surface. The size of the hole is preferably small in order to maintain the mechanical strength of the bottom surface. The shape of the hole can be formed into various shapes such as a square shape and a circular shape, and the size is, for example, preferably 30 mm or less, preferably 20 mm or less, and more preferably 10 mm or less.

In the present invention, a water-absorbing mixed layer containing a plastic waste material pulverized material, a paper waste material pulverized material, and a water-absorbing resin is provided in contact with the water-absorbing paper layer portion. In this water-absorbing mixed layer portion, the plastic material content is set to be larger than the pulp content, and is formed by mixing the crushed plastic waste material with the crushed paper waste material. When the crushed paper waste is paper powder, crushed milk pad waste, crushed urine pad waste, or crushed sanitary napkin waste, these crushed waste materials have a relatively high plastic substance content, Because of the extremely high pulp content and high water-absorbent resin content, furthermore, plastic waste material pulverized materials, for example, synthetic resin fiber waste material pulverized material, rayon fiber waste material pulverized material,
The crushed polyethylene film powder, the crushed polypropylene film material, and the crushed synthetic rubber material can be added and mixed. Further, as the crushed paper waste material, crushed paper having a low pulp content, for example, waste paper such as punch waste or cutting waste of book paper, or crushed paper waste material in which the pulp content is increased by classifying the crushed material is used. it can. Furthermore, in addition to these, as crushed paper waste materials, crushed paper diaper waste materials,
For crushed milk pad waste material, crushed hip pad waste material, crushed sanitary napkin waste material, or a mixture of two or more waste material crushed materials of the crushed waste material, it is possible to use a pulp-rich classified product obtained by performing a classification treatment. it can.

In the present invention, when a defective sanitary material such as a disposable paper diaper, a milk pad, a hip pad or a sanitary napkin is used as a paper waste material, the waste material includes a plastic material, paper powder, and a water absorbent resin. The amount of the added plastic waste material and superabsorbent resin can be reduced, and the mixing operation is simplified, which is preferable. The cutting waste generated during the production of the sanitary material, and the so-called dust collection loss in which the dust generated during the cutting contains the paper powder of the plastic material and the pulp material powder. And it can be used as crushed paper waste. Since the cutting waste or dust collection loss generated during the production of these sanitary materials has a small content of the water-absorbent resin or the superabsorbent resin, it is necessary to add and mix the water-absorbent resin or the superabsorbent resin. In the present invention, it is possible to use pulp waste having bactericidal and deodorant properties as the pulp material.

In the present invention, the absorbent has a water-absorbing paper layer formed of thin paper such as water-absorbing paper on each of the front side and the back side. The thin paper such as water-absorbing paper is, for example, a tissue paper having a basis weight of 12.5 g / m 2, and can be arranged one by one on each of the upper and lower sides. In the present invention, when the absorber is used as a sheet for humans or animals, for example, two sheets of water-absorbing paper on the upper surface can be used, and the water-absorbing paper positioned at the uppermost part can be used as the water-absorbing paper for inspection. In this case, the water-absorbing paper may contain two or more inks generally containing a pH detection reagent, an ink containing a protein detection reagent, an ink containing an occult blood detection reagent, an ink containing a urobilinogen detection reagent, or the detection reagent. Can be printed. In this way, by making the upper absorbent sheet at least two sheets and printing the detection reagent on the uppermost absorbent sheet, it is possible to avoid the influence of paper dust and superabsorbent resin on the printed detection reagent. This is preferable since accurate detection can be performed. Further, in the present invention, when tissue paper having a sterilizing property is used as the tissue paper, the odor generated by sweat, urine, etc. attached to the absorber, the sheets or the packaging material is reduced in the use of the absorber, sheets and packaging material. preferable.

In the present invention, the water-absorbent resin-containing layer portion comprises:
It may be formed only of a water-absorbing resin, or may be mixed with various water-absorbing materials in addition to the water-absorbing resin to form, for example, an absorbent mixed layer portion. In order to make the absorber retain water absorbency, a super water absorbent resin is blended. The superabsorbent resin used in the present invention is 30 to 100 times its own weight with artificial urine.
The resin is preferably a resin capable of retaining its shape even when absorbing about twice as much 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. When used for waste oil treatment or the like, a water-absorbent resin having high oil absorbency is used.

In the present invention, it is preferable to use a so-called superabsorbent resin having high water absorbency as the water absorbent resin contained in the waste material, since the amount of use can be reduced. In the present invention, the term water-absorbent resin also means a water-absorbent resin having a lower water-absorbing ability than a higher-water-based resin, in addition to a higher-water-based resin. In the present invention, when only the waste paper diaper waste material is used, the high water-absorbing resin is preferably 14 to 28% by weight of the absorber and can maintain high water absorption, which is preferable. 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 has a poor water absorption performance of 10 to 30 g / g in artificial urine, but it has been found that the absorbent can be sufficiently used with such a water absorbing effect. The particle size of the superabsorbent resin used is preferably from 50 to 500 μm.

When a pulverized material of the punch dust is added to the paper dust of the waste material, the particle size of the pulverized material of the punch dust is reduced, and the used amount thereof is 3 to 20% by weight or less of the paper powder, preferably. The content is preferably 3 to 10% by weight or less. In the present invention, plastic waste material, pulp waste material and water-absorbent resin waste material used in the water-absorbing mixed layer portion are each 5 mm or less, preferably 3 mm or less, in order to increase the water absorption and water retention.
It is preferably used after being ground to a particle size of mm. In the present invention, the composition of the absorber when the water-absorbing paper is arranged vertically one by one (12% by weight of the total weight of the absorber) is such that the content of the water-absorbing resin is 14 to 28% by weight. The pulp content of the crushed waste material (paper powder) is 40% by weight or less,
The content of the crushed plastic waste material is preferably 50% by weight or less.

In the present invention, the absorbent comprises an upper water-absorbing paper layer forming an upper surface, a lower water-absorbing paper layer forming a lower surface, and a plastic waste material pulverizing material between the upper and lower water-absorbing paper layers. Material, a paper waste material pulverized material and a water-absorbing mixed layer portion containing a water-absorbing resin, and the upper water-absorbing paper layer portion, the water-absorbing mixed layer portion and the lower water-absorbing paper layer portion are laminated and integrally formed. And, on one surface thereof, a plurality of recesses or protrusions having a size of 3 mm or more, preferably 4 to 8 mm are formed, so when the absorber is arranged on the floor,
The absorber absorbs water drops falling on the floor, but the surface of the absorber can be kept relatively dry, and the floor can be prevented from getting wet.

Therefore, for example, the floor of an open-air event venue or the ground of an athletic ground is prevented from getting wet by rain, the floor of a kitchen, the floor of a washroom, the floor around a refrigerator, the floor of a toilet, etc. Water droplets can be absorbed to prevent the floor from getting wet. Further, for example, it can be used as a bed mat to prevent the bed of a patient with enuresis from getting wet. It can be used as a water-absorbent mat for wiping dew on a ceiling, a wall or a window of a building to remove dew on a window or the like. When used as a water-absorbing mat for preventing evaporation of water for gardening, which is moistened in advance and covered with a potted plant, the evaporation of water from the potted plant due to water retention can be prevented. The water-absorbent mat can be laid, for example, under the marine product, or the water-absorbent mat can be formed into a bag to wrap the marine product and transport the marine product without contact with thawing water.

The present invention also provides an upper water-absorbing paper layer forming an upper surface, a water-impermeable thin layer forming a lower surface, and a lower water-absorbing sheet provided with the lower surface in contact with the water-impermeable thin layer. And an absorbent pulverized material mixture layer containing a pulverized waste plastic material, a pulverized paper waste material and a water-absorbent resin between the upper and lower water-absorbent paper layer parts, and the upper water-absorbent paper layer part. The water-absorbent resin-containing layer portion, the intermediate water-absorbent paper layer portion, the water-absorbent mixed layer portion, and the lower water-absorbent paper layer portion are laminated and integrally formed, and one surface has a size of 3 mm or more. Since a plurality of concave portions or convex portions are formed and a surfactant is attached, a hole is made in an impermeable thin layer portion such as a plastic film, and the impermeable thin layer portion such as a plastic film is formed. Water permeable so that water from the wet floor can be absorbed from below It can be. Further, in the absorbent body and sheets of the present invention, even if the water entering from the upper surface is a relatively large amount such as urine, the water is not formed on the surface portion, but is stored in each concave portion, The water stored in the concave portion can be relatively quickly absorbed by the water-absorbing mixed layer portion to which the surfactant is attached by coating or the like by the action of the surfactant. As described above, the absorber and the sheets of the present invention reduce the amount of pulp material to be used by half, and even if supplemented with the crushed material of plastic waste material, maintain the predetermined mechanical strength and remove water drops falling on the floor. It can absorb and eliminate the wetting of water. Therefore, for example, the umbrella stand is disposed at the receiving portion to absorb water drops flowing down from the wet umbrella, so that water does not accumulate in the umbrella stand.

Further, the absorbent body and the sheet of the present invention are characterized in that the absorbent body and the sheet have a water-permeable thin layer portion such as a nonwoven fabric forming the upper surface,
A water-impermeable thin layer portion such as a plastic film forming a lower surface, an upper water-absorbing paper layer portion disposed in contact with the lower surface of the water-permeable thin layer portion, and a lower surface of the upper water-absorbing paper layer portion. Water-absorbing mixed layer portion containing a mixture of plastic waste material powder, paper waste material powder and water-absorbing resin, and a lower water-absorbing paper layer portion disposed in contact with the lower surface of the water-absorbing mixed layer portion. Further, the water-impermeable thin layer portion is disposed below the lower water-absorbent paper layer portion, and the upper water-absorbent paper layer portion, the water-absorbent resin-containing layer portion, and the intermediate water-absorbent paper. The layer portion, the water-absorbing mixed layer portion, and the lower water-absorbing paper layer portion are laminated and integrally formed.
Since a plurality of recesses or protrusions having a size of at least mm are formed and a surfactant is attached, the plastic waste material can be effectively used as a material for the absorber and the sheets, and furthermore, it was obtained. Absorbents and sheets can prevent human or animal excreted urine from visibly accumulating on the surfaces of the absorbents and sheets, have good absorption, good water retention, and are also resilient. Good to use as bedding. Plastic films such as polyethylene film and polypropylene film have a high combustion heat and are considered to damage combustion furnaces. By mixing with the stock contained in the absorbent to make the absorbent, the heat of combustion of the absorbent can be increased by the amount including the plastic film, so that rainwater, water, urine, sweat, etc. attached to the absorbent after use Even if the heat of combustion is reduced due to moisture, poor mixing of the absorbent after use can be improved by mixing the plastic film, and the processing of the plastic film waste can be facilitated, and the cost of processing the waste can be reduced.

According to the present invention, a water-absorbing mixed layer portion provided between an upper water-absorbing paper layer portion and a lower water-absorbing paper layer portion can be formed by pulverized waste titanium paper, pulverized alumina paper waste, A crushed product of potassium acid paper waste material, a crushed product of alumina / silica paper waste material or a crushed material of inorganic fiber paper waste material such as a carbon fiber paper waste material, or a mixture of two or more of the crushed materials of the inorganic fiber paper waste material is used as at least a part of the paper waste material. It is used to mix the waste plastic waste material and the water-absorbent resin into an absorber,
The odor removing function of the crushed inorganic fiber paper waste material in the absorber can be used as a sheet to remove the odor generated in the sheet at the time of use, thereby reducing the odor of the sheet after use. When used for packaging fruits and vegetables, freshness of the fruits and vegetables can be maintained by removing ethylene, which is a mature hormone generated from the fruits and vegetables.
