Description

The present invention relates to a biodegradable composition and various substrates using the same. More specifically, the present invention relates to a biodegradable composition used for deodorization, adhesion, interior / bedding, medical care, cosmetics, agriculture, household goods, or packaging / distribution-related base materials.

At present, plastics made from petroleum are widely used in various fields. Regarding this, the disposal method after use is a major problem. In other words, in landfill disposal, the space left at the disposal site is running short because it remains indefinitely. In addition, incineration disposal generates intense heat to damage the incinerator and, depending on the incineration situation, generates extremely harmful dioxin or bromo-based dioxin analogues, so that disposal of the incineration ash is troublesome.
In contrast, microbial plastics such as polyhydroxybutyrate or biodegradable chemically synthesized polylactic acid, polycaprolactone, polyalkylene succinate or polyvinyl alcohol, chemically modified cellulose or starch have been proposed. However, they are expensive, inferior in workability, inadequate in mechanical strength, and inferior in biodegradability, and thus do not completely satisfy the market requirements. Further, a mixture using a mixture of starch and a petrochemical plastic has been proposed, but the amount of added starch is small, and many of them have essentially no biodegradability, which is a problem. Further, Japanese Patent No. 2804523 proposes a mixture of starch and urea, which is reversibly disintegrated by water, and is therefore of little practical use in the field aimed at by the present invention.

On the other hand, interest in health, the environment, effective use of renewable resources and rationalization of logistics is increasing in society at large, such as products for sick houses, products for the elderly, products using reproducible materials, etc. Is required. In addition, people are more sensitive to odors and antibacterial activity, and products for deodorizing various antibacterial odors and antibacterial products are being actively developed. In addition, there is a growing demand for external beauty, regardless of gender, and there is also a need to develop products that respond to this. Many products have been sold and many proposals have been made in response to such market needs, but they have not yet completely met the market requirements.

The present invention is inexpensive, can be produced by a simple method, and when used in landfill disposal or in the natural world, it is biodegraded by bacteria in the soil, etc., and its capacity is greatly reduced. Is a biodegradable base material that does not generate harmful substances such as dioxin and has a function of absorbing aldehydes by itself, absorbing and releasing moisture, and being gentle on fruits and vegetables and humans (skin).

The biodegradable composition of the present invention and various substrates using the same are suitable for deodorization, adhesion, interior / bedding, medical care, cosmetics, agriculture, household goods or packaging / distribution-related substrates, and are gentle on the human body. It is inexpensive, easy to dispose of and can be produced in a simple manner.

Hereinafter, the present invention will be described in detail. In the present invention, starches, urea or urea derivatives and polyhydric alcohols are used as basic materials. As a feature of the present invention, the content of inexpensive urea or a urea derivative is as high as 60 to 300% by weight with respect to starch, which is effective in lowering the price of the composition, and has a high deodorizing property of aldehyde odor. It has high moisture absorption and desorption properties, and is effective for softening the stratum corneum of the skin or alleviating drug barrier properties related to the transdermal absorption of drugs. In addition, the mixture gels at room temperature in the presence of a small amount of water (up to 300% by weight with respect to the starch) to form a temporary molded product (agar-like, gelatin-like), which is advantageous in production, and is also advantageous in heat. It becomes easy to add a material that is easily volatilized and decomposed. Also, if necessary, by heating to 50 to 70 ° C., it is possible to form a highly flexible, dry-molded product, and in addition to having a moisture-absorbing and releasing property, Since it is heat retroactive, it can be used in many forms as commercial products. When the dried molded article is immersed in water, unlike the case of Japanese Patent No. 2880423, it absorbs and swells. However, since the molded article retains its original shape and does not collapse, it can be applied to a wide range of products.

Examples of the starch used in the present invention include potato, corn, tapioca, those derived from cereals such as wheat or rice, and from the moldability, mechanical strength and the like, tapioca and starch derived from rice are particularly preferable. For rice, old rice and old rice can be used effectively. Examples of the acetylated starch include acetylated potato starch, acetylated corn starch, and acetylated tapioca starch, and preferably acetylated corn starch and acetylated tapioca starch, more preferably acetylated starch, from the viewpoint of moldability and mechanical strength. Tapioca starch. Further, acetylated starch is preferable to unmodified starch from the viewpoint of strength and water resistance as a base material, and the mixing ratio of unmodified starch and acetylated starch is from 0: 100 to 40; 60. Acid-treated starch is the same as raw starch or acetylated starch in strength and water resistance as a base material, but has a low viscosity at the time of gel formation, and may be appropriately mixed and used when used as a cream or paint. preferable. Hydroxypropylated starch is excellent in strength and water resistance as a base material, but is expensive, so that it is preferable to appropriately use it according to the purpose.

The urea or urea derivative used in the present invention includes urea, dimethyl urea, dihydroxyethyl urea and the like. The amount used is 60 to 300, preferably 80 to 250, more preferably 100 to 200% by weight based on the starch. If it is less than 60, the gelation rate is low and the uniformity is poor. If it is more than 300, the formed gel becomes brittle.

The polyhydric alcohol used in the present invention is added for imparting plasticity to the gel molded body, and specifically, polyethylene glycol such as ethylene glycol, diethylene glycol, polyethylene glycol # 200, polyethylene glycol # 400 Glycerols such as glycerol, diglycerol, polyglycerol # 4, propylene glycol, dipropylene glycol, butanediol, glucose, sorbitol and the like. The amount used is 10 to 150, preferably 20 to 100% by weight based on the starch. If it is less than 10, the plasticity becomes insufficient, and if it is more than 150, the strength of the gel decreases. In addition, glucose and sorbitol are suitable for the field which does not like stickiness of the dry molded product.
In the present invention, in addition to the above-mentioned starches, ureas and polyhydric alcohols used as basic materials, an aqueous resin can be added to improve the mechanical strength or water resistance of the base material. Specifically, polyvinyl alcohol (many brands are commercially available from Nippon Gosei Co., Ltd. or Kuraray Co., Ltd.), and among them, Gohsenol GH17, NH20 (both products of Nippon Gosei Co., Ltd.) or Kuraray Poval PVA 220 and 120 (both products of Kuraray Co., Ltd.) or a polyethylene-vinyl alcohol copolymer (Nippon Gosei Co., Ltd. or Kuraray Co., Ltd.) )), Many brands are commercially available, and these can be used), or methoxymethylated nylon (Tresin FS350, FS500, EF30T, etc., commercially available from Nagase Chemtex Co., Ltd. can be used) or aqueous polyester polyol Resin (commercially available from Nagase ChemteX Corporation) Such Gabusen ES901,905, or Toyobo Co. such as VYLONAL MD1100,1400 are commercially available from, or the like manufactured by Dai such Paogen PP15 commercially available from, Ltd. is available) and the like. The amount added is 0 to 100, preferably 10 to 50% by weight based on the starch. When it is 50 or less, the biodegradability is good. If it is more than 50, the biodegradability decreases, but if it is less than 100, biodegradation is substantially possible.

Further, aluminum hydroxychloride or colloidal silica may be added to improve the surface hardness or water resistance of the base material. The amount added is 0 to 20, preferably 2 to 20% by weight based on the starch. Even if the number is more than 20, the effect will level off.

Further, in order to improve the mechanical strength or commercial properties of the base material, a thread, cloth or granule derived from a natural material may be added. The addition amount is 0 to 1000, preferably 10 to 1000% by weight based on the starch. Examples of natural materials include paper, cotton, hemp, wool, silk, kenaf, copra, coco, cork, and the like. These yarns or cloth or cloth are finely torn, defibrated (fluffed), or ground. Object is used. Examples of the supply source of such materials include rejected products and wastes in producing fibers and paper, and used clothes or used paper.

Phosphoric acid may be added in order to improve the flexibility or flame retardancy of the substrate. Phosphoric acid alone has a flame retardant effect, but when used in combination with urea, the flame retardant effect is further enhanced. The addition amount is 0 to 200, preferably 10 to 200% by weight based on the starch. Even if it exceeds 200, the effect will level off.

In addition, in order to improve the flame retardancy of the base material, 0 to 300, preferably 10 to 300% by weight of folic acid and / or aluminum hydroxide and / or calcium hydroxide and / or magnesium hydroxide and And / or melamine and / or bow salt (decahydrate) may be added.

It can be used by attaching.
In addition, when the base material of the present invention is attached to a granular, thread-like, or cloth-like material derived from a synthetic resin, the surface of the synthetic resin is subjected to a corona discharge treatment or the surface is separately anchor-coated with a resin. It is preferable to improve the adhesiveness.

The basic substrate of the present invention composed of the above-mentioned materials can be used as a heat-removing sheet or mask (can maintain a suitable humidity, and can also hold a drug for the throat and nose) without adding an active agent as described below. It can be used for creams and sheets for repairing bulkiness (especially heels), cracks, etc., housings for home appliances and miscellaneous goods, hot melt type adhesives, solidifying agents for aqueous harmful substances, and the like.

Hereinafter, various activators used in the present invention will be described. First, the active substance used in the composite deodorant used in the present invention will be described. The group A substances used in the present invention are effective in absorbing aldehydes. The starches and ureas used in the basic substrate also have the ability to absorb aldehydes, but the addition of substances of group A further enhances the ability to absorb aldehydes. Examples of the aldehydes include formaldehyde released from a formaldehyde condensation-based adhesive used for furniture and building materials, acetaldehyde contained in cigarette smoke, and nonylaldehyde emitted by the elderly.
Among the substances in Group A, polyallylamine (for example, PAA commercially available from Nitto Boseki Co., Ltd. can be used), monoethanolamine, polyoxyalkylene polyamine (for example, commercially available from San Techno Chemical Co., Ltd.) JEFFAMIN), basic amino acids such as lysine or arginine, guanidine salts such as guanidine hydrochloride, guanidine sulfate, guanidine sulfamate or guanidine phosphate, gallic acid, tannic acid, ammonium sulfate , Sodium sulfite, casein and sericin are effective. In particular, polyallylamine, monoethanolamine, polyoxyalkylenepolyamine, lysine, arginine, guanidine hydrochloride, guanidine sulfate, guanidine sulfamate or guanidine phosphate and citric acid, organic acids such as lactic acid, polyacrylic acid or swelling The composite with the clayey mineral is effective because the stability of the aldehydes is kept as it is and the stability is improved. The amount of the organic acid or polyacrylic acid used may be 0.6 to 1.2 weight ratio with respect to the amines. If it is less than 0.6, the effect is weak, and if it is more than 1.2, the effect level out. The amount of the swellable clay mineral to be used is 1 to 10 weight ratio with respect to the amines. If it is less than 1, the effect is low, and if it is more than 10, the effect level out. Long-chain aliphatic amines such as stearylamine or oleylamine are particularly effective in absorbing aging odors such as nonylaldehyde, and are ortho, meta or paraphenylenediaminesulfonic acid, phenylenediaminedisulfonate, orthoaminophenolsulfonic acid. Besides, dialkoxyanilines such as dimethoxyaniline and diethoxyaniline, alkoxyacylaminoanilines such as methoxyacetylaminoaniline and ethoxyacetylaminoaniline, and aminonaphthalenes such as 2-aminonaphthalene-6,8-disulfonate Aminonaphtholsulfonic acids such as sulfonic acid and H acid are effective for absorbing formaldehyde and acetaldehyde. Composites of these amino group-containing compounds with basic acids, polyacrylic acids or swelling clay minerals are more effective because they have improved stability in addition to aldehyde absorption. The amount of the organic acid or polyacrylic acid used is, for example, 0.6 to 1.2 weight ratio with respect to the amines. If it is less than 0.6, the effect is weak, and if it is more than 1.2, the effect level out. The amount of the swellable clay mineral to be used is 1 to 10 weight ratio with respect to the amines. If it is less than 1, the effect is low, and if it is more than 10, the effect level out. 1,8-dihydroxynaphthalene, chromotropic acid, 2-hydroxy-4-methyl-5-cyano 6-pyridone, 2-hydroxy-4-methyl-5-carbamido-6-pyridone, acetoacetylaminobenzenesulfonic acid, acetoacetylaminobenzenecarboxylic acid Is effective in absorbing aldehydes in general. Composites of these compounds and swellable clay minerals are more effective because they have improved stability in addition to aldehyde absorption. The amount of the swellable clay mineral to be used is 1 to 10 weight ratio to these compounds. If it is less than 1, the effect is low, and if it is more than 10, the effect level out.

Swellable clay minerals include bentonite, smectite (montmorillonite), vermiculite, hydrotalcite, etc. The complex structure with such clay minerals is unknown, although the detailed structure and theory are unknown. Its use is advantageous because it is stabilized without reducing the reactivity to the aldehyde.

The addition amount of these substances (including the composite) is 1 to 30, preferably 3 to 20% by weight based on the basic substrate. If it is less than 1, the effect is poor, and if it is more than 30, the strength of the substrate is reduced.

The basic substrate of the present invention has high hygroscopicity and depends on the use environment conditions. However, since it contains humidity (moisture) in a normal state, it easily absorbs (dissolves) aldehydes, and the activator ( The reaction with the (reactant) is also facilitated, which is effective for removing aldehydes.

The group B substances used in the present invention are effective in neutralizing amine-based malodors. Organic acids include lactic acid, citric acid, glycolic acid, malic acid, sorbic acid and the like. The polyacrylic acid is used as a free acid (for example, julimer AC10L commercially available from Nippon Pure Chemical Co., Ltd. can be used). The addition amount of these substances is 1 to 20, preferably 3 to 15% by weight based on the basic substrate. If less than 1, the effect is poor, and if it is more than 20, the strength of the substrate decreases.

The group C substances used in the present invention are effective for the adsorption and decomposition of hydrocarbons such as toluene, thinner and ethylene. As the divinylbenzene-based polymer, Diaion HP 20, 21 or Sepabeads SP 825, 850 available from Mitsubishi Chemical Corporation can be used. These are water-insoluble fine particles having many hydrophobic fine pores, and have a high ability to adsorb hydrocarbons. However, if the characteristics and the entire surface of the particles are covered with the basic base material, the ability cannot be sufficiently exhibited, so it is necessary to devise a method for exposing the surface of the particles. Specifically, it is possible to adjust the film thickness of the basic substrate to be smaller than the particle diameter, or to sprinkle the particles on the basic substrate and perform thermocompression if necessary.

As a styrene-maleic acid copolymer effective for adsorption of hydrocarbons, SMA 1000, 2000, 3000 or the like manufactured by Arco Chemical Co., Ltd. may be used as it is or hydrolyzed, or SMA 1440, 2625 which is a half ester Etc. can be used. Among them, SMA 2000, 3000, 2625 having a high styrene content is advantageous. A wide range of commercially available styrene-acrylic acid copolymers can be used, and those having a high styrene content are also advantageous. As the sulfonated polystyrene, Polyty PS available from Lion Corporation can be used. For long-chain unsaturated aliphatic acids such as abietic acid, soybean oil, oleic acid, and alpha-olefin sulfonic acid, those widely available commercially can be used. Commercially available products such as cinnamic acid, diallyldimethylammonium chloride, acetylene glycol or an ethylene oxide adduct thereof, and cyclodextrin can also be used. Those substances which can be dissolved in water can be used as they are in the basic substrate of the present invention, and those which are hardly soluble in water can be emulsified and used. It is more effective when used in combination with the above-mentioned divinylbenzene polymer.

As a decomposing agent for ethylene or amines, hypochlorite includes sodium salt, which can be used in the state of being dissolved in water contained in the basic substrate of the present invention. However, since it also has decomposability with respect to the base material, it is preferable to use it as a complex with hydrotalcite. The amount of hydrotalcite to be used may be 3 to 10 weight ratio to sodium hypochlorite. If it is less than 3, the damage to the basic substrate is large, and if it is more than 10, the decomposition ability is reduced.

The addition amount of these substances (including the composite) is 1 to 25, preferably 3 to 20% by weight based on the basic substrate. If less than 1, the effect is poor, and if it is more than 25, the strength of the substrate decreases.

The group D substances used in the present invention are effective for oxidative decomposition of sulfur-containing substances such as mercaptans or sulfides. KI3, folic acid or sodium folic acid is preferred because it can be stably present in moisture and starch in the basic substrate. A complex of KI3 and hydrotalcite is more preferred. The amount of hydrotalcite to be used may be 1 to 5 weight ratio to KI3. If it is less than 1, the damage to the basic substrate is large, and if it is more than 5, the decomposition ability is reduced.
Potassium iodate can be suitably used as the halogenate, and a complex of potassium iodate and hydrotalcite is more preferable. The amount of the hydrotalcite to be used is, for example, 2 to 10 weight ratio to potassium iodate. If it is less than 2, the damage to the basic substrate is large, and if it is more than 10, the decomposition ability is reduced.

The addition amount of these substances (including the composite) is 1 to 15, preferably 3 to 10% by weight based on the basic substrate. If less than 1, the effect is poor, and if it is more than 15, the strength of the substrate decreases.

The group E substances used in the present invention are effective in absorbing oxygen or carbon dioxide gas. The amount of addition is 5 to 30, preferably 10 to 25% by weight based on the basic substrate. If less than 5, the effect is poor, and if it is more than 30, the strength of the substrate decreases.

The substance of Group F used in the present invention is effective in releasing carbon dioxide gas, if necessary, in combination with an organic acid. The amount of addition is 5 to 30, preferably 10 to 25% by weight based on the basic substrate. If less than 5, the effect is poor, and if it is more than 30, the strength of the substrate decreases.

The substances of the groups A, B, C, D, E, and F used in the present invention are all water-soluble or hydrophilic (even hardly soluble), and have a high basic moisture-absorbing and desorbing property. Have good compatibility, and there is no harm when mixed and used. For example, when the amines of Group A are used in a free form, the solubility in water is low or unstable, but when used in combination with the organic acids of Group B or Group C or polyacrylic acid, a weak salt is formed. Thus, the above problem is solved. In the present invention, by combining three or more substances from the groups A, B, C and D, a complex odor containing an aldehyde odor, an acid odor, an amine odor, a hydrocarbon odor or a sulfur-containing compound odor is mixed. Deodorization can be performed efficiently.

As the disposable diaper base material or the elderly care base material, a base material which is effective in absorbing urine odor and aging odor by using a large amount of the above-mentioned composite deodorants, especially the substances of the A, B and D groups. For example, it can be used in the form of granules or strips mixed with the superabsorbent resin particles, or in the form of a film or fabric, used as a pillow cover, futon cover, sheets, underlaying sheets, or as a support medium for superabsorbent resin particles. It is effective to use it for the outermost phase of a diaper by utilizing its high moisture absorbing and releasing properties.

As a building substrate, it can be used as an adhesive, a paint, a wall material or a wallpaper. As an adhesive, formaldehyde can be suppressed by adding it to a commercially available formaldehyde condensed resin-based adhesive in the form of a cream, or used as a new hot-melt adhesive in the form of gelatin, granules or films. it can. By using a large amount of the substances in Groups A, C, and D and coating it as a wall material itself, or as a paint on the surface of the wall material, or using it as a wallpaper, the odor of formaldehyde or organic solvent (hydrocarbon) It is effective for sick house measures due to odor, etc. or for deodorizing complex odors such as body odor, tobacco odor and pet odor.

As a base material for interior or bedding, it is used for sofa cushions and cushions, curtains, carpets, carpet underlays, bedspreads, etc., and measures against sick houses due to formaldehyde odor or organic solvent odor (hydrocarbon odor), body odor, and tobacco odor It is effective for deodorizing household odors such as pets and pets. As a form, a form suitable for a product such as a thread form, a granular form, a film form, or a knitted fabric form is possible.

When the base material of the present invention is used in a situation where human eyes can see it, coloring is also an important factor as a product. Since the base material of the present invention does not use activated carbon or the like, it is almost white, but if necessary, is colored with a synthetic dye or a dye derived from a natural material having a high affinity (directness) with starches. It is possible to do. In particular, the use of natural dyes has high ecology suitability and is advantageous as a commercial product.

The basic substrate of the present invention is water-absorbing, in which case an endothermic effect is observed, presumably due to the dissolution of urea. By applying water to the dried basic substrate and then applying it to the forehead or the affected part of the heat, it is possible to effectively remove the heat in combination with the heat removal by the latent heat of evaporation of the water.

The basic substrate of the present invention has a high concentration of urea or a polyhydric alcohol, and has a strong ability to penetrate the active substance by softening the stratum corneum of the skin while absorbing and releasing moisture. Therefore, it is useful as a disposable diaper substrate, a wound covering substrate, a percutaneous medical substrate or a cosmetic substrate. For example, as a base material for disposable diapers, a base material to which sericin, fibroin, amino acid, casein, gelatin, chitosan, hyaluronic acid, chondroitin sulfate, etc. are added as an active substance to a basic base material, in a film form or a knitted form. By using the diaper at the site where the diaper comes into contact with the skin, it is possible to prevent skin soreness and pressure sores. The addition amount of the active substance is 1 to 20% by weight based on the basic substrate. If less than 1, the effect is poor, and if it is more than 20, the mechanical strength of the substrate decreases. As described above, the basic base material of the present invention alone has a strong keratin softening force, but salicylic acid may be added for further strengthening. The addition amount is 0 to 10, preferably 1 to 10% by weight based on the basic substrate.

As a base material for wound covering, an active substance such as sericin, fibroin, amino acid, casein, gelatin, glucosamine, chitosan, collagen, atelocollagen, hyaluronic acid, chondroitin sulfate, pectin, heparin, glucuronic acid, or alginic acid is used as a basic substrate. Such a biocompatible material or a substrate to which antibacterial agents such as silver nitrate, silver sulfadiazine, gentamicin, hinokitiol, allyl isothiocyanate, and hiba oil are added, as a highly flexible non-dry gel (jelly-like) By using this, it is possible to bring the affected area into close contact without causing pain. As the antibacterial agent, natural products derived from hinokitiol, allyl isothiocyanate, and hiba oil are preferable.These products can be used as they are, or as aqueous solutions such as ethanol, ethylene glycol, glycerin, diethylene glycol monobutyl ether, triethylene glycol dimethyl ether, and cellosolve acetate. By dissolving it in a hydrophilic or hydrophilic organic solvent and impregnating it with a porous material such as divinylbenzene polymer or diatomaceous earth as it is or with a solution to form a composite, the effect can be maintained for a long time. Is more preferable. As for the antibacterial agent, a highly hydrophobic and highly compatible divinylbenzene-based polymer is more preferable as the porous material. The amount of the biocompatible material to be added is 2 to 20% by weight. If less than 2, the effect is poor, and if more than 20, the effect levels off. The usage ratio of the porous material to the antibacterial agent may be 10 to 100 weight ratio.

Various kinds of packaging by adding a volatile rust inhibitor, ethylene gas absorbing / decomposing agent, carbon dioxide absorbing / generating agent, oxygen absorber, antibacterial / antifungal / insect / miticidal agent to the basic substrate of the present invention.・ Substrates for distribution, storage, interior use or water-based paints are obtained. In any case, these base materials are easy to dispose and have high moisture absorption / desorption properties, so that they are particularly useful for precision equipment, logistics and storage of fruits and vegetables, fresh fish, meat, etc., interior materials, and water-based paints. Examples of the vaporizable rust preventive include dicyclohexylamine nitrite, diisopropylamine nitrite, cyclohexyl ammonium cyclohexyl carbamate and the like. Such a vaporizable rust inhibitor is impregnated into a porous material such as diatomaceous earth or preferably a highly hydrophobic and highly compatible divinylbenzene-based polymer, and this is added to a basic substrate, A substrate for packaging / distribution or for water-based paint is obtained. In addition to being able to have both functions of absorbing moisture and preventing rust when moisture infiltrates when transporting equipment, it is effective for painting rust-resistant iron products.

As the ethylene gas adsorbing / decomposing agent, the above-mentioned group C substances are used. It is said that the ripening of fruits and vegetables such as apples and bananas and flowers such as roses and carnations is related to ethylene gas generated by themselves, and the removal of this ethylene gas maintains the freshness of fruits and vegetables and flowers. (In distribution process, home refrigerator, etc.). It is also important to maintain an appropriate humidity in the system during transportation of fruits and vegetables and flowers, and the basic substrate of the present invention has high moisture absorption and release properties and is suitable. In addition, since there is a buffering action, there is little damage to the individual. The addition amount of the group C substance (including the composite) is 5 to 25% by weight based on the basic substrate. If it is less than 5, the effect is poor, and if it is more than 25, the strength of the base material decreases.

Carbon dioxide gas is generated by the contact between the carbonate and the acid. Both magnesium carbonate and calcium carbonate have low water solubility, exist as particles in the base material, react with coexisting acids while dissolving a trace amount of water in the base material, and generate carbon dioxide gas. The particle size of the carbonate is preferably 0.5 mm to 3 mm. The water solubility of the organic acid also decreases as the organic acid increases. That is, it is considered that the amount of generated carbon dioxide is intricately entangled with the water content in the base material, the water solubility of the carbonate, the particle size of the carbonate, the water solubility of the acid, and the diffusion rate of the acid. Polyacrylic acid is preferred in the sense that the diffusion rate is slow in order to maintain the effect for a long time.

As a specific utilization method, there are a system in which a carbonate and an acid coexist and a system in which a carbonate and an acid do not coexist during the production of a base material. When carbonates and acids coexist at the time of production, the operation at the time of use is simple, but carbon dioxide gas starts to be produced from the time of production, and storage is complicated. The basic substrate of the present invention is dried at the time of production to suppress the water content to a low level. Even if stored as it is, the generation of carbon dioxide gas is very small and there is little problem. On the other hand, when mixed with the fruits and vegetables as described above, the moisture generated by the fruits and vegetables is absorbed, the moisture in the base material is increased, and the generation of carbon dioxide gas is increased, so that practicality can be exhibited. At the time of use, water may be separately provided as necessary. In addition, a substrate having only carbonates is prepared, and when used, by applying an aqueous solution of the acid to the substrate, it takes time and effort to use, but it is easy to store, and only when it is necessary to generate carbon dioxide gas. And efficient. The concentration of the acid is preferably as high as possible. The basic substrates of the present invention are suitable for absorbing aqueous solutions of acids.

The amount of the carbonate added is 3 to 10% by weight based on the basic substrate. If it is less than 3, the effect is poor, and if it is more than 10, the mechanical strength of the substrate becomes insufficient. The amount of the acid to be added is 2 to 20% by weight based on the basic substrate, including when the aqueous solution is applied. If it is less than 2, the effect is poor, and if it is more than 20, the mechanical strength of the substrate becomes insufficient.

At the time of distribution, as for the cushioning material for preventing the contents from being damaged, etc., the basic substrate of the present invention is flexible itself, as it is, has a buffering effect, and utilizes the fact that it is thermoplastic. The base material can be made circular or twisted to enhance the buffering effect. It is also possible to heat the finely cut object (tip, strap, etc.) and fuse it at the contact point of the cut object to further improve the buffering property. In order to further enhance the buffering property, foaming is performed by generating carbon dioxide gas in the base material using baking soda and organic acids (citric acid, tartaric acid, oxalic acid, succinic acid, polyacrylic acid, etc.) when forming the base material. Thus, a cushioning material can be obtained. The amount of baking soda is 3 to 30% by weight based on the basic substrate, and the amount of acid is 2 to 25% by weight.

A material impregnated with a porous material such as a mineral or preferably a highly hydrophobic and highly compatible divinylbenzene polymer is used in addition to the basic substrate. The amount of the porous material used is 10 to 100 weight ratio to the antibacterial and antifungal agent. Since this base material is made of a highly safe substance and has high moisture absorption and desorption properties, it can be used in refrigerators or cupboards, or bedding such as bedding, bedding or bed sheets, or carpet bedding. It can be used for interior materials. The amount of the antibacterial / antifungal agent added is 0.1 to 10% by weight based on the basic substrate. If it is less than 0.1, the effect is poor, and if it is more than 10, the mechanical strength of the substrate becomes insufficient or odor becomes a problem.

Examples of insecticides and acaricides include methoxadiazon, permethrin, phenothrin, phthalthrine, resmethrin, hiba oil, eucalyptus oil and the like. Pyrethroids act as contact poisons for insects and mites. These agents are added to a basic substrate to form a film, and the surface is covered with a thin cloth (sandwich). Then, an insecticidal / miticidal substrate excellent in moisture absorption / release properties can be obtained by using it as a carpet underlay under a tatami mat. The insecticide and acaricide can be used as it is or dissolved in a water-soluble or hydrophilic organic solvent such as ethylene glycol, glycerin, diethylene glycol monobutyl ether, triethylene glycol dimethyl ether, or cellosolve acetate to obtain a clay mineral or a divinylbenzene polymer. A material impregnated in a porous material such as described above is used in addition to the basic substrate.

Preparation of patch: To 200 parts of water, 100 parts of acetyl tapioca starch, 100 parts of urea, 10 parts of glycerin, 20 parts of glycerin monolaurate, and 20 parts of SP850 containing nicotine were added, and a uniform slurry mucus was prepared using a homogenizer. The mucus was applied on an aluminum-evaporated PET film having a thickness of 150 μm to a thickness of 3 mm using an applicator, and then left at room temperature for 3 hours to gel into a gelatinous state (patch A). Similarly, a gelatinous gel was prepared using nicotine-containing diatomaceous earth (patch B).
Application: As a result of attaching 20 square cm of the patch to the chest of an addicted smoker, patch A withstood 24 hours of non-smoking. On the other hand, it took 18 hours for patch B. Both patches A and B showed high practicality. Regarding the difference between the two, it is considered that Sepabeads had higher lipophilicity (hydrophobicity) and higher compatibility with nicotine than Keiso earth, and could release nicotine for a long time. Sepabeads are considered to be more advantageous for stable release over a long period of time.
Storage stability: A non-smoking test was conducted using a patch that was covered with a 200 micron thick polypropylene (PP) film on the gel of the patch, sealed in a PP bag, and stored at room temperature for 6 months. On patch A, Patch A survived 24 hours of non-smoking. Patch B was 15 hours. The gel state of both patches A and B was as good as before the storage test. This is probably because Sepabeads SP850 has a high affinity for volatile and lipophilic nicotine. Further, it is supposed that Sepabeads SP850 (divinylbenzene-based polymer fine particles) has few polar groups, has a chemically stable structure, has a high degree of crosslinking, and withstands chemical attack by nicotine. Such stable divinylbenzene-based polymer fine particles are not biodegraded at the time of disposal, which is contrary to the purpose of the present invention. However, it is considered that the amount used is small and does not pose a practical problem. . Conversely, these fine particles contain water, have high water retention, are breathable, and are useful for soil improvement.
