2. Description of the Related Art Conventionally, for example, the floor is wetted by using a cloth rag or a disposable rag, and a stick rag attached with various absorbents such as a rag, a waste cloth and a sponge. Water-absorbent mats are laid in places such as washrooms that get wet in advance 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 part in contact with the inside of the water-impermeable membrane, and contact with the inside of the water-impermeable thin layer part of the bottom part of the sheet, and the lower water-absorbent film. A paper layer portion is provided, and paper powder containing a highly water-absorbent resin is arranged between the upper and lower paper layer portions. In addition, currently, a large amount of paper products are produced and consumed, but a large amount of cutting waste is generated at the printing stage and the bookbinding stage according to each application, and the amount thereof is enormous and recycled. There is.

[0005]

However, cloth rags and bar rags are used repeatedly, and in order to be able to reuse the used rags, rinsing and adhering water are required. This is a problem because it requires a lot of trouble such as squeezing it out and replacing it, and changing the rinsing water. In addition, paper powder and super absorbent resin are used for conventional disposable sheets, and in particular, pulverized pulp is used for paper powder. However, pulverized pulp products have been difficult to obtain lately and are relatively expensive, so that their use is problematic in terms of cost. Therefore, in disposable sheets, the crushed pulp is reduced, and a super absorbent polymer is used in place of the crushed pulp. However, by reducing the amount of crushed pulp, the absorbent material such as disposable sheets using a superabsorbent resin is formed relatively thin due to the small amount of crushed pulp used, resulting in poor elasticity. Since it becomes a relatively hard absorber, the reduction of pulp crushed matter is a problem for disposable diapers and the like. On the other hand, when transporting marine products, the marine products are placed on straw or paper and transported, but the straw or paper gets wet due to thawing, etc., and the marine products being transported continue to contact the wet straw or paper. That is a problem.

Further, paper diapers and sanitary napkins are manufactured in large quantities and consumed in large quantities, but at the time of cutting at the time of manufacture, a water-absorbing layer portion or plastic containing paper powder and a superabsorbent resin as raw materials. A large amount of film cutting waste is generated.
Plastic film cutting waste has a high combustion heat of the plastic material, and its treatment has been a problem.
The processing is problematic. Furthermore, when recycled waste paper is recycled, it is used as a building material such as wallpaper because mixing of plastic materials and metal materials is a problem.
For example, chemical fiber papers, inorganic fiber papers, metal fiber papers, fiber papers containing metal oxides, plastic film waste materials, and the like are not used as raw materials except for a problem. The present invention is a problem relating to the raw materials and reuse of conventional absorbent materials such as rags and mats, or the problem relating to the raw materials and elasticity of sheets, and the disposal of inorganic fiber paper, plastic film waste materials and paper diaper waste materials. It aims to solve problems.

[0007]

Means for Solving the Problems The present inventor uses an absorbent material which is a crushed material obtained by crushing a sanitary material waste material such as a defective sanitary material containing plastic material and sanitary material cutting waste. It can be used as an absorber without impairing its performance, and the presence of a plastic material increases the heat of combustion of the absorber after use, allows self-combustion to continue, and also saves fuel during incineration. The present invention was accomplished by discovering that a function of removing odors and the like can be imparted to the absorber by using waste titanium paper, waste alumina paper, waste potassium titanate paper, alumina / silica paper and the like as raw materials for the absorber.

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the absorbent body can be used as an absorbent body for various uses, as a direct sheet, or as a direct packaging material. A non-woven fabric is placed, a waterproof sheet is placed on the bottom, and it is formed into a sheet shape, which can be used as a rug, for example, as animal sheets, or as various sheets for rest and sleep, etc. Can be used as mat and packaging material.

In the present invention, a convex portion is formed on the surface of the absorbent body. The convex portion supports the water-permeable thin layer portion forming the upper surface of the sheet or the packaging material, and the water-permeable thin layer portion. It forms a space for accumulating water underneath, whereby the water that is not absorbed in the absorbent body and remains on the surface of the absorbent body is absorbed on the water-permeable thin layer portion of the sheet or the packaging material, for example, the nonwoven fabric. It can be retained and give the nonwoven 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. As described above, with regard to recesses or protrusions such as depressions formed in the absorbent body, the height of the absorbent body including the thickness of the absorbent body is within the range of the thickness that can be used as the absorbent body, sheets, or packaging material, and is circular. Or, it can be formed in a polygonal shape so as to project upward or downward. In this case, the male mold surface of the male mold of the pair of the male mold and the female mold is formed to have a plurality of convex portions, and at the position corresponding to the convex portion of the mold surface of the other molding die. A concave portion having a corresponding shape is formed, and a plurality of convex portions such as protrusions are formed on one surface of the absorber, for example, the upper surface, and the other surface of the absorber, for example, the lower surface, corresponds to the convex portion of the upper surface. Then, a concave portion, for example, a depression is formed. But,
It is possible to form a plurality of protrusions such as protrusions or recesses such as depressions on the mold surface of one of the pair of molds, and form the mold surface of the other mold on 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 an absorber having a thickness of m is used, the height of the protrusions provided, for example, the protrusions is 0.5 to 1.5 mm, and the total 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 thin, 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 convex portion, for example, a protrusion. 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 protrusions such as protrusions provided is 0. The thickness of the absorber provided with the convex portion, for example, the protrusion is 0.8 to 4.5 mm. In this case as well, it is preferred that the thickness of the absorber is thin, so the thickness of the absorber is 0.7
The thickness of the absorber provided with the convex portion, for example, the protrusion is preferably 1.
It is preferably 2 to 3.6 mm.

The size of each of the plurality of hole-shaped recesses or depressions or projections or projections formed independently on the surface of the absorber is, for example, the diameter when the projections or depressions in a plane have a circular shape. 2-12 mm, preferably a chevron-shaped projection with a circular base having a diameter of 4-8 mm, a cylinder having a diameter of 2-12 mm, preferably 4-8 mm or a diameter of 4
In the case where the shape of the projection or the depression on the plane is a quadrangle,
It is preferable that the length of one side is a quadrangle having a length of 2 to 12 mm, preferably 4 to 8 mm. Further, when the shape of the protrusion or the depression on the plane is a polygon, it is measured in the direction crossing the center of the protrusion or the 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 larger than the thickness of the absorber in 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 in this manner, the non-woven fabric covering the absorber is held by the convex portion or the ridge-shaped convex portion, and Since it is positioned stably in the non-woven fabric, a space for storing the liquid is formed under the non-woven fabric, so that the liquid remaining on the non-woven fabric permeates the non-woven fabric and stays in the space of the liquid reservoir, The residence time can be shortened. Therefore, when the concave portion formed on the upper surface of the absorbent body is formed in a shape that surrounds the convex portion and partially communicates with each other, the volume of the liquid storage space can be increased and the retention time of the liquid on the nonwoven fabric can be shortened. preferable.

In the present invention, when compression molding is performed by using a female mold for molding the upper surface and a male mold for molding the lower surface, the upper surface of the absorbent body, for example, the surface is independent. Then, the convex portion can be formed, and the concave portion can be formed on the surface opposite to the convex portion, for example, on the corresponding portion of the rear surface. On the contrary, when 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 concave portion is formed on the front surface, and the opposite surface, for example, the rear surface. The convex portions can be formed at the corresponding positions. However, if a male or female mold is used to mold the upper surface and a flat surface mold is used to mold the lower surface, the upper surface will have multiple independent protrusions or projections or communicate with each other. It is possible to form a concave portion to form a flat lower surface. In the present invention,
Embossing or creping may be performed before forming the convex portion and the concave portion.

In the present invention, the term recess means an independent recess or depression and a recess or trough that is continuous in at least a portion, likewise a protrusion is an independent protrusion or projection and at least a portion. Means a continuous ridge or convex ridge. In the present invention, when an independent recess or depression is formed on one surface, for example, the front surface, surrounded by continuous ridge-shaped projections, correspondingly, the other surface, for example, the back surface, is continuously formed. It can be compression-molded so as to form independent protrusions or projections surrounded by groove-shaped or valley-shaped recesses, and can also be surrounded by continuous valley-shaped recesses on one surface, for example, the surface. When a 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 depression can be formed surrounded by continuous ridge-shaped convex portions or convex stripes. be able to. In these cases, an uneven pattern on one surface or the other surface can be selected and 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 into a cylindrical, conical, prismatic or pyramidal protrusion or a ridge-shaped protruding portion or ridge, while the concave portion is cylindrical, conical, It can be formed in a bottomed hole or groove having a prismatic shape or a pyramid shape.

In the present invention, in order to increase the water absorption capacity of the absorbent body, the upper and lower portions of the absorbent body are formed by the water absorbing paper layer portion. This water-absorbent paper layer portion is formed by laminating or laminating one or more tissue papers, thin papers such as rayon papers or composite papers one by one,
Alternatively, it may be formed of a water-absorbent paper formed by a plurality of thin papers that are previously combined and integrated. If the number of thin paper sheets is increased, the water absorption speed of the absorber can be increased. In this case, the thin paper can be colored with a color former that develops color when wet with water or a color former that reacts with water to form a color. As the water absorbent paper, it is possible to use absorbent composite paper obtained by laminating thin paper and chemical fiber paper. In the present invention, in order to increase the water retention capacity of the absorbent body, between the upper and lower water-absorbent paper layer portions, a plastic waste material pulverized material, a paper waste material pulverized material and a water-absorbent mixed layer portion containing a water-absorbent resin are provided. The upper and lower water-absorptive paper layer portions and the water-absorptive mixed layer portions that are provided may be integrally combined or integrally laminated to form an absorber having a convex portion on at least the upper surface.

When the water-permeable thin layer portion is used, it may 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 permeation function depending on the degree of water permeation. By configuring the absorber in this way, for example, by arranging it on a floor surface that is wet with rain, etc., it is possible to automatically absorb water that wets the floor surface, and there is no need to wipe off the wetness of the floor surface. Can be omitted. Thus, the sheet having the water-permeable thin layer portion can be used as a rug for vehicles, a rug for an umbrella stand, a rug for a washroom, a rug around a toilet bowl, etc. to prevent each floor from getting wet. . Also,

There are used tickets discharged from airplanes and highways, and in addition to these, used paper discharged from various service areas such as highways, leisure facilities, parking lots, and beverage manufacturing plants Containers, such as used paper cups and paper trays, defective paper cups, and the like. These waste paper materials are pulverized into pulverized products having a particle size of 5 mm or less, preferably 3 mm or less. The pulverized product of these paper waste materials is used for an absorber as a pulverized product of one type of paper waste material or a mixture of pulverized products of two or more types of paper waste materials.

As the crushed plastic waste material and the crushed paper waste material used for such an absorber, a crushed product of a defective product containing a plastic material and a pulp material and a cutting waste generated at the time of manufacturing the product, etc. There is a crushed material of the waste material. Examples of such crushed plastic waste materials and crushed paper waste materials include crushed waste products of sanitary goods including paper and crushed scraps thereof, and particularly crushed scraps of defective paper diapers and scraps of paper diapers.

In addition to these, even if the pulp content is small, shredded scraps shredded by a document shredder such as high-quality paper, computer paper, office paper or printing paper, that is, shredder scrap paper, punch scrap paper, titanium paper,
Alumina paper, alumina silica paper, potassium titanate paper or carbon fiber paper or wet or dry non-woven fabric or a combination of two or more of these paper waste materials and / or a combination of these paper waste materials with the above paper waste materials is used as an absorber. It can be used as a waste paper component. In the present invention, titanium paper, alumina paper, alumina silica paper and potassium titanate paper are fiber papers containing titanium dioxide, alumina, alumina silica or potassium titanate, respectively, and are used as wallpaper, for example. Is.

In the present invention, in order to increase the texture and elasticity of the absorbent body, the content of the crushed plastic waste material used in the water-absorbent mixed layer portion is made larger than the content of the crushed paper waste material. be able to. In this case, the water absorption rate of the water-absorbing mixed layer portion will decrease as much as the content of the pulverized waste material of valp will decrease, and water will remain on the surface of the absorber without being absorbed for a while. Therefore, in the present invention, a plurality of independent recesses or recesses that are continuous with each other are formed on the surface of the absorbent body, and the residual water on the surface of the absorbent body is made to flow into the recesses to be accommodated. I am trying. However, the water that has flowed into the concave portion remains without being absorbed in the water-absorbent mixed layer portion because the water-absorbent mixed layer portion has a low water-absorption rate.

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 absorbent resin is mixed to absorb water. The water retention capacity and water absorption capacity of the mixed layer are increased. As described above, by adhering the surfactant to, for example, the front surface and / or the back surface of the absorbent body, the water accumulated in the recesses can be quickly absorbed by the absorbent body, and the water absorbent resin is mixed to absorb the water. Water can be absorbed and retained in the functional mixture layer portion. In the present invention, by forming a concave portion on the surface of the absorbent body, the surface area in contact with water is increased, and by further adhering a surfactant to the concave portion, the water absorption rate of the absorbent body is increased. It is possible to absorb water promptly. As the surfactant, anionic surfactants such as sodium dodecylbenzene sulfonate are preferable, but in addition to these, cationic surfactants such as lauryl trimethyl ammonium chloride, nonionic surfactants such as octyl phenyl ether, etc. is there. In the present invention, by thus forming the concave portion or the convex portion on the surface of the absorber and attaching the surfactant, it is possible to alleviate the residual water on the surface of the absorber.

In the present invention, in the case of forming a sheet, when the nonwoven fabric layer portion is formed on the surface of the absorbent body so that the convex portion formed on the absorbent body supports the nonwoven fabric layer portion, the sheet is formed. This is preferable because it is possible to prevent the non-woven fabric layer on the surface of the substrate from getting wet and water from seeping out from the non-woven fabric layer. In the present invention, in order to increase the water absorbing ability of the absorber and the sheets, a water absorbing paper layer portion formed of thin paper is provided on the upper and lower portions of the absorber. In order to increase the water-retaining capacity of the absorbent body, a water-absorbing mixed layer portion containing crushed plastic waste material, crushed paper waste material and water-absorbing resin is provided between the upper and lower water-absorbing paper layer portions, and the upper portion. The lower water-absorbent paper layer portion and the lower water-absorbent mixed layer portion are integrally bonded to form an absorber.

In the present invention, the upper water-absorbent paper layer portion, the lower water-absorbent paper layer portion, and the crushed plastic waste material, the crushed paper waste material and the water-absorbent resin provided between the upper and lower paper layer portions are used. The water-absorbing mixed layer portion containing the same is embossed and pressure-molded into a relatively flexible plate-like body. Such a relatively flexible plate-like body is preferable because it adheres well to the floor portion and easily absorbs water drops and the like on the floor.
In the present invention, an intermediate water-absorbent paper layer portion can be arranged between the upper and lower water-absorbent paper layer portions. When the water-absorbent paper layer portion is composed of three layers in this way, the water-absorbent resin-containing layer portion can be formed between the upper water-absorbent paper layer portion and the intermediate water-absorbent paper layer portion. If only water absorbency is required and elasticity is not required, only the water absorbent resin can be arranged, but if elasticity is required as well as water absorbency, plastic waste powder is added to the water absorbent resin. In addition, elasticity can be given.

In the present invention, the sheet has a water-permeable thin layer portion forming the upper surface, and this water-permeable thin layer portion is a nonwoven fabric or polyethylene made of plastic fiber such as polypropylene, polyethylene, nylon or vinylon. , A polypropylene, vinyl chloride resin, or other plastic material porous film. The lower part is a water-impermeable plastic film layer part, and the plastic film layer part is polyethylene, as in the case of the absorber. It can be formed of a water-impermeable thin layer made of plastic such as polypropylene. In the present invention, a water absorbing paper layer portion may be provided inside the water permeable thin layer portion so as to be in contact with the inner side surface thereof. In the present invention, it is preferable to use, as the water-permeable thin layer portion, a material to which sterilization and deodorizing properties are imparted, because the odor generated by perspiration or urine attached during use is reduced. 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 body, sheets and packaging material are soiled. It is preferable because it can be buried inside and discarded. In the packaging material of the present invention, when the upper and lower surfaces are water permeable,
Both the upper and lower sides can be water-permeable thin layer portions such as a nonwoven fabric. In the present invention, water permeability means a property of water permeability, and for example, a certain amount of water or simulated urine (25
(ml) is injected into a circle of 2 cm, it is determined by the time (seconds) required for permeation of the entire amount of water or simulated urine,
The shorter the permeation time, the better the water permeability than the longer one. In the present invention, the water-permeable thin layer portion has, for example, 25 ml of water and a diameter of 2 mm within 10 seconds from the nozzle of the washing bottle.
When injected into a circle of cm, it is preferable that the time for the whole to penetrate is within 20 seconds.
That is, the shorter the water permeability is, the more preferable.

In the present invention, it is preferable that the upper, middle and lower water-absorbent paper layer portions are made of thin paper such as absorbent paper, water-absorbent paper or crepe paper because good water absorption can be secured. Further, in the present invention, as the water-absorbent paper, a composite paper manufactured by dispersing pulp and chemical fibers in a liquid and making a paper can be used. It is possible to use a composite paper having a water-absorbing property or a water-permeable property, which is obtained by sticking synthetic fiber paper such as polypropylene-made chemical fiber paper to thin paper. In the present invention, the water-absorbent paper layer portion is provided as an upper water-absorbent paper layer portion in contact with the lower surface of the water-permeable thin layer portion, and the lower water-absorptive paper layer portion is provided on the bottom of the absorbent body. It may be formed, and the bottom surface can be reinforced by forming the bottom surface with a thin layer made of impermeable plastic. In this case, the lower water-absorbent paper layer portion may be provided in contact with the inner surface, that is, the upper surface of the water-impermeable plastic layer portion. When the bottom portion is formed of the water-impermeable plastic thin layer portion, it is preferable to make a hole in the plastic thin layer portion in order to absorb the liquid such as water from the bottom surface. The size of the holes is preferably small in order to maintain the mechanical strength of the bottom surface. The holes can be formed into various shapes such as a square shape and a circular shape, and the size thereof is, for example, 30 mm or less, preferably 20 mm or less, more preferably 10 mm or less.

In the present invention, a water absorbing mixed layer portion containing a crushed plastic waste material, a crushed paper waste 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 substance content rate is set to be higher than the pulp content rate, and it is formed by mixing the pulverized waste paper material with the pulverized waste plastic material. If the pulverized waste paper is paper dust, crushed dairy pad waste, crushed urine pad waste, or crushed sanitary napkin waste, these waste pulverized products have a relatively high content of plastic substances. Since it has a relatively high pulp content and a high water-absorbent resin content, further, a plastic waste material pulverized product, for example, a synthetic resin fiber waste material pulverized material, a rayon fiber waste material pulverized material,
The polyethylene film waste material pulverized product, the polypropylene film waste material pulverized product, and the synthetic rubber waste material pulverized product can be added and mixed. Further, as the crushed paper waste material, a waste paper having a low pulp content, such as punch scraps or cutting scraps of ledger paper, or a crushed paper waste material with a high pulp content rate by classifying the crushed materials is used. it can. Furthermore, in addition to these, as the paper waste material crushed product, paper diaper waste material crushed product,
It is possible to use a pulp-rich classified product obtained by classifying dairy pad waste material crushed material, hip pad waste material crushed material, or sanitary napkin waste material crushed material, or a mixture of two or more waste material crushed materials of the waste material crushed material. it can.

In the present invention, when a defective sanitary material such as a defective paper diaper, a milk pad, a hip pad or a sanitary napkin is used as a waste paper material, it contains a plastic material, paper powder and a water-absorbent resin. The amounts of the crushed plastic waste material and the superabsorbent resin to be added 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 of the dust generated during the cutting contain paper powder of the plastic material and the pulp material powder, and thus, for example, are crushed to be a plastic waste material crushed product. It can also be used as a pulverized product of waste paper. 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 super-absorbent resin, it is necessary to add and mix the water-absorbent resin or the super-absorbent resin. In the present invention, it is possible to use waste of waste pulp material having bactericidal and deodorant properties as the pulp material.

In the present invention, the absorbent body has a water-absorbent paper layer portion formed of thin paper such as water-absorbent paper on each of the front side and the back side thereof. The thin paper such as water-absorbent paper is, for example, a tissue paper having a basis weight of 12.5 g / m @ 2, and can be placed one above the other. In the present invention, when the absorbent body is used as a sheet for humans or animals, for example, two water-absorbent papers on the upper surface can be used, and the water-absorbent paper located at the top can be used as the test water-absorbent paper. In this case, the water-absorbent paper contains, in the ink containing a commonly used pH detection reagent, ink containing a protein detection reagent, ink containing a occult blood detection reagent, ink containing a urobilinogen detection reagent, or two or more of the detection reagents. Can be printed. In this way, at least two water-absorbent paper on the top, and by printing the detection reagent on the water-absorbent paper on the top, it is possible to avoid the influence of paper powder and super absorbent resin on the printed detection reagent. This is preferable because it can be performed and accurate detection can be performed. Further, in the present invention, when a thin paper having sterilizing property is used as the thin paper, in the use of the absorbent body, the sheet and the packaging material, the odor generated by sweat or urine adhering to the absorbent body, the sheet or the packaging material is reduced. preferable.

In the present invention, the water-absorbent resin-containing layer portion is
It may be formed of only the water-absorbent resin, or various water-absorbent materials other than the water-absorbent resin may be blended to form, for example, the absorbent mixed layer portion. A super water-absorbent resin is blended in order for the absorbent body to retain water absorbency. The super absorbent polymer used in the present invention is artificial urine in an amount of 30 to 100 times its own weight.
It is preferable that the resin retains its shape even if it absorbs about twice as much water. Examples of such a super absorbent resin include, for example, saponified copolymer of vinyl ester and ethylenically unsaturated carboxylic acid or its derivative, graft polymer of starch and acrylic acid, crosslinked product of polyacrylic acid, vinyl alcohol. And acrylic acid copolymers, polyacrylonitrile partial hydrolysates, carboxymethyl cellulose cross-linked products, polyethylene glycol cross-linked products, chitosan salts or pullulan gels. These are used alone or in admixture of two or more kinds with the water-absorbing material powder. When used for waste oil treatment and the like, a water absorbent resin having a high oil absorption property is used.

In the present invention, the water-absorbent resin contained in the waste material is preferably a so-called super-water-absorbent resin having a high water-absorbing property because the amount used can be reduced. In the present invention, the term “water-absorbent resin” means, in addition to the high-grade water-based resin, a water-absorbent resin having a lower water-absorbing capacity than the high-grade water-based resin. In the present invention, it is preferable to use only waste waste diaper waste, since the superabsorbent resin accounts for 14 to 28% by weight of the absorber, and can maintain high absorbency. In the present invention, as the superabsorbent resin, for example, a superabsorbent resin-containing material recovered from waste diaper material can be used. It has been found that such a regenerated super absorbent resin has a poor water absorption capacity of 10 to 30 g / g in artificial urine and its water absorption performance is poor, but it can be sufficiently used in an absorber with such a water absorption effect. The particle size of the super absorbent polymer used is preferably 50 to 500 μm.

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

[0035]

In the present invention, the absorbent body comprises the upper water absorbent paper layer portion forming the upper surface, the lower water absorbent paper layer portion forming the lower surface, and the plastic waste material crushed between the upper and lower water absorbent paper layer portions. And a water-absorbent mixed layer portion containing a crushed material of paper waste and a water-absorbent resin, and the upper water-absorbent paper layer portion, the water-absorbent mixed layer portion and the lower water-absorbent paper layer portion are bonded and integrally formed. Since a plurality of recesses or protrusions having a size of 3 mm or more, preferably 4 to 8 mm are formed on one surface thereof, when the absorbent body is placed on the floor,
The absorber absorbs water drops that fall 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, it is laid on the floor of an open-air event venue or the ground of a playground to prevent it 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 drops can be absorbed to prevent wetting of the floor. It can also be used, for example, in a bed mat to prevent bedwetting of patients with nocturnal enuresis. It can be used as a water-absorbent mat for wiping off dew condensation on a ceiling, wall or window of a building to remove dew condensation on windows. Further, when used as a water-absorbent mat for preventing water evaporation for horticulture by preliminarily moistening it and covering it with potted plants or the like, it is possible to prevent water evaporation from the potted plants due to water retention. The water-absorbent mat can be laid, for example, underneath the aquatic product, or the water-absorbent mat can be formed into a bag shape, and the aquatic product can be wrapped so that the aquatic product can be transported without contact with the defrosted water.

Further, according to the present invention, the upper water-absorbent paper layer portion forming the upper surface, the water-impermeable thin layer portion forming the lower surface, and the lower water-absorbing layer provided with the lower surface in contact with the water-impermeable thin layer portion. Water absorbent paper layer portion and an absorbent pulverized material mixed layer containing a crushed plastic waste material, a crushed paper waste material and a water absorbent resin are provided between the upper and lower water absorbent paper layer portions, and the upper water absorbent paper layer portion is provided. 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 bonded and integrally formed, and one surface thereof has a size of 3 mm or more. Since a plurality of recesses or protrusions are formed and a surfactant is attached, a hole is made in the water-impermeable thin layer portion of the plastic film or the like, and the water-impermeable thin layer portion of the plastic film or the like is formed. Water permeable so that wet floor water can also be absorbed from the bottom surface It can be. Further, in the absorbent body and the sheet of the present invention, even when the water invading from the upper surface is a relatively large amount such as urine, it does not form a pool of water on the surface portion, but is stored in each recessed portion, The water stored in the recesses can be absorbed relatively quickly by the action of the surfactant in the water-absorbing mixed layer portion to which the surfactant is attached by coating or the like. As described above, the absorbent body and the sheet of the present invention reduce the amount of pulp material to be used by half, and even when supplemented by the pulverized material of the plastic waste material by that amount, the predetermined mechanical strength is maintained and water drops falling on the floor are retained. It can absorb and eliminate the wetness of the water. Therefore, for example, it is arranged in the receiving part of the umbrella stand and absorbs the water droplets flowing down from the wet umbrella, so that water does not collect in the umbrella stand.

Further, the absorbent body and the sheet of the present invention include, for example, a water-permeable and water-permeable thin layer portion such as a non-woven fabric forming the upper surface,
A water-impermeable thin layer portion such as a plastic film forming a lower surface, an upper water-absorbent paper layer portion arranged in contact with the lower surface of the water-permeable thin layer portion, and a lower surface of the upper water-absorbent paper layer portion. A water-absorbent mixed layer portion containing a mixture of waste plastic powder, waste paper powder and a water-absorbent resin, and a lower water-absorbent paper layer portion disposed in contact with the lower surface of the water-absorbent mixed layer portion. And the water-impermeable thin layer portion is disposed below the lower water-absorbent paper layer portion, and further, the upper water-absorbent paper layer portion, the water-absorbent resin-containing layer portion, and the intermediate water-absorbent paper sheet. The layer portion, the water-absorbent mixed layer portion and the lower water-absorbent paper layer portion are adhered to each other to be integrally formed, and one surface thereof has a 3
Since a plurality of concave portions or convex portions having a size of mm or more are formed and a surfactant is adhered, the plastic waste material can be effectively used as a material for the absorbent body and the sheet, and it was obtained. Absorbents and sheets can prevent urine excreted by humans or animals from visibly accumulating on the surface of the absorbents and sheets, and have good absorption, good water retention, and elasticity. Good to use as bedding. Plastic films such as polyethylene film and polypropylene film have high combustion heat and damage the combustion furnace, which is a problem. By mixing with the paper material contained in to form an absorber, the heat of combustion of the absorber can be increased by the amount including the plastic film, so rainwater, water, urine, sweat, etc. that adhere to the absorber after use Even if the heat of combustion decreases due to water content, mixing of the plastic film can improve the combustion failure of the absorber after use, facilitate the disposal of the plastic film waste material, and reduce the waste material disposal cost.

According to the present invention, the water-absorbent mixed layer portion disposed between the upper water-absorbent paper layer portion and the lower water-absorbent paper layer portion is formed by crushing titanium paper waste material, crushed alumina paper waste material, and titanium. At least a part of the paper waste material is a pulverized product of potassium acid paper waste material, a pulverized product of alumina / silica paper waste material, a pulverized product of inorganic fiber paper waste material such as carbon fiber paper waste material, or a mixture of two or more of the inorganic fiber paper waste material pulverized products. Used as the absorbent material by blending crushed plastic waste material and water-absorbent resin into it.
By the odor removing function of the pulverized waste inorganic fiber paper in the absorber, it can be used as a sheet to remove the odor generated in the sheet during use, and can reduce the odor of the sheet after use. When used for packaging fruits and vegetables, freshness of fruits and vegetables can be maintained by removing ethylene, which is a mature hormone generated from fruits and vegetables.

In the absorbent body 1 of these examples, for example, on the upper surface of the absorbent body 1, a plurality of protrusion-shaped or chevron-shaped convex portions 5 protruding upward are formed, and the convex portions 5 are surrounded so as to be separated from each other. A plurality of groove-shaped or valley-shaped recesses 6 that are partially continuous with each other are formed and integrally molded. In this example, a plurality of concave portions 6 can be formed instead of the plurality of convex portions 5. In this case, it is possible to integrally form the absorber 1 by surrounding the concave portions 6 so as to be separated from each other and forming the ridge-shaped convex portions 5 that are partially continuous with each other. In this case, in order to increase the volume of the concave portion, that is, the volume of the liquid storage space, a ridge-shaped convex portion is formed so that a plurality of concave portions communicate with each other or the height of the convex portion increases. Is preferred.

On the formed water-absorbent mixed layer portion 3, a water-absorbent paper formed of one or more thin papers is placed as an upper water-absorbent paper and pressure-molded to form a plurality of water-absorbent papers on the upper surface of the absorbent body 1. The absorber 1 is formed by forming the protrusions 5, enclosing the formed protrusions 5 so as to be separated from each other, and forming grooves or valley-shaped recesses 6 that are partially continuous with each other. In this case, convex portions and concave portions are formed on the upper surface of the absorber 1, plural concave portions are formed on the lower surface corresponding to the plural convex portions on the upper surface, and ridge-shaped convex portions are formed on the lower surface corresponding to the concave portions on the upper surface. However, it is possible to form the convex portion and the concave portion on the upper surface of the absorber 1 and to form the lower surface flat. In this example, a plurality of recesses 6 can be formed instead of the plurality of projections 5. In this case, the ridge-shaped convex portions 5 are formed so as to surround the concave portion 6 so as to be separated from each other and are partially formed to be integrally formed as the absorber 1. In this example,
In order to increase the water absorption rate of the absorbent body 1, the aqueous surfactant solution may be sprayed and adhered onto the pulverized material mixture layer 3 of the absorbent body 1. In this case, a water-absorbent paper formed of one or more thin papers can be arranged as the upper water-absorbent paper 4 on the pulverized material mixture layer to which the surfactant (not shown) is attached by spraying. In this example, the water-absorbent mixed layer portion is formed by placing a mixture of crushed plastic waste material, crushed paper waste material and water-absorbent resin, but a mixture 16 of crushed plastic waste material and crushed paper waste material It is possible to place the water absorbent paper 2 on the water absorbent paper 2 and sprinkle the water absorbent resin 17 on the entire surface thereof to form the water absorbent mixed layer portion 3 (see the absorbent body 1 in FIG. 13). A water absorption test was conducted on the absorbent body 1 of this example. In the water absorption test in these examples, 25 ml of simulated urine was added to the circle of 20 mm in diameter of the absorber within 10 seconds from the nozzle of the washing bottle for analysis, and the added artificial urine was absorbed on the surface of the absorber in the circle. It was done by measuring the time remaining on the surface without being done. In the case of the absorbent to which the surfactant was not attached, the residual time of the simulated urine was about 3 to 4 seconds, but the absorbent to which the surfactant was adhered had the residual time of the artificial urine of about 2 seconds. ~ 3 seconds, the retention time of simulated urine was shortened by 1/4 to 1/2 compared with the absorbent without the surfactant attached, and it was confirmed that the use of the surfactant is effective. . The artificial urine was prepared by adding 10 g (g) of salt and 10 ml of ammonia water to 1000 ml (ml) of tap water, mixing and stirring to dissolve.

In this case, a plurality of convex portions can be formed on the lower surface corresponding to the plurality of concave portions on the upper surface, but in this case also, the convex portion or the concave portion is formed on the upper surface of the absorber 1 and the lower surface is formed flat. be able to. In any case, the plurality of protrusions 5 or the plurality of recesses 6 may be formed on the upper surface to integrally form the absorber 1. In the absorbent body 1 of this example, on the upper part of the pulverized material layer 3 of the defective paper diaper 3, 1 ml of a sodium dodecylbenzenesulfonate solution prepared by diluting 1 ml of anionic surfactant sodium dodecylbenzenesulfonate with 74 ml of water was used. A layer (not shown) sprayed with 5 ml is formed, and an upper water-absorbent paper 4 (1.4 g) is placed on the water-absorbent mixed layer portion 3 sprayed with this surfactant solution. . For the absorbent body produced in this way, simulated urine 2
5 ml was added to one point of the absorber within 10 seconds by a syringe, and the time required for the total amount to be absorbed was measured by measuring the time that the artificial urine added to one point remained on the surface without being absorbed by the absorber. It was about 1 to 2 seconds. This result is
It was the same as the conventional absorbent body using pulp and super absorbent polymer. The combustion heat of the absorber 1 in this example is 6684.
Although it is kilocaloric (kcal) / kg, for example, even after being used for sheets and mats and absorbing a double amount of water, poor combustion does not occur.
