Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an antibacterial humidity control material which is a mixture of a softwood processed product having an antibacterial function, a phytoncide function and a humidity control function, and a porous material having a humidity control function, and to various products. It is about application.

[0002]

2. Description of the Related Art In recent years, as an agent for preventing mold, termites, and wood rot fungi that are generated under the floor of a house in the rainy season and in winter.
Conditioning coal using wood charcoal that keeps the humidity under the floor low is used. Generally, humidified coal is laid directly in the soil between roses. This humidified charcoal only has a humidity control action of absorbing and releasing humidity, and cannot be expected to have a bactericidal action and repellent action against mold, termites, and wood rot fungi. In addition, although it is manufactured industrially, it is not economical and widely used in ordinary houses because there is no low-cost carbonization furnace and it takes time to carbonize.

[0003] As houses become highly insulated and airtight, harmful gases such as formaldehyde and ammonia gas in the rooms have a problem on the human body. Also,
The air humidity in the room tends to be excessively humid, and allergic patients due to molds and ticks that abnormally reproduce in high humidity environments are increasing. In particular, rice straw is used as the core material of the tatami mat.
Many kinds of mites are breeding from the beginning in large quantities in the material of rice straw using the sugar content of straw as a nutrient source. Also. A large number of blue molds can be generated from tatami rushes in the rainy season in a closed house without a long-term absence. On the other hand, because of the difficulty in obtaining rice straw, tatami mats using lightweight styrofoam as a core material are widely used. The disposal of old and new tatami mats is currently being incinerated. Disposal of incinerated ash generated by the combustion of styrofoam and smoke pollution have become problems.

[0004] As the long-term storage of agricultural products is increased, low-temperature refrigerators are introduced in the agricultural storages, and the small refrigerators are packed in plastic bags capable of controlling gas exchange related to the metabolism of the agricultural products to maintain the freshness. Furthermore, an adsorbent for adsorbing ethylene gas is placed in a plastic bag to prevent quality deterioration. This method has a drawback that the adsorbent is individually packed in a plastic bag, and a labor-saving method has been desired. On the other hand, in large-scale storages such as cereals, a freshness preserving agent is generally not used to avoid trouble.

[0005]

SUMMARY OF THE INVENTION A first object of the present invention is to provide a humidity control effect in order to prevent molds, termites, and wood rot fungi from forming under the floor of a house during the rainy season or winter.
It is an object of the present invention to disclose a low-cost antibacterial humidity control material having a combined effect such as a bactericidal effect and a building material for antibacterial humidity control. A second object of the present invention is to improve the living environment in a house by removing harmful gases generated from new building materials, disinfecting molds and ticks generated under excessive humidity, and respiratory diseases caused by excessive dry humidity. An object of the present invention is to disclose an antibacterial humidity control panel material having a combined effect such as a preventive effect on illness and a relaxing effect on a human body by conifer phytoncide. A third object of the present invention is to remove ethylene gas generated from agricultural products, adjust oxygen and carbon dioxide to control the metabolism of agricultural products, and promote overdry humidity to promote quality deterioration in order to maintain long-term freshness of agricultural products storage. It is an object of the present invention to disclose an antibacterial humidity control panel material having a combined effect such as a humidity control effect for preventing humidification and a bactericidal effect for putrefactive bacteria by conifer phytoncide.

[0006]

The first gist of the present invention is as follows.
An antibacterial humidity control material and a building material for antimicrobial humidity control, which is a mixture of a porous material and a coniferous processed material used to suppress the generation of mold, termites, and wood rot fungi generated under the floor of a house. It is in.

[0007] Charcoal mixed with large and small charcoal is produced in a stationary carbonization furnace for about one week from bark, Sega, and the like discarded from a wood sawmill. Also, relatively fine charcoal is continuously produced by a continuous carbonization furnace using heavy oil as a fuel, using chips and wood chips of thinned wood as raw materials. In both cases, labor costs and carbonization furnaces are expensive, and it is difficult to significantly reduce costs. On the other hand, coniferous tree bran is used in large quantities at low cost as a medium component for artificial cultivation of mushrooms.
In mushroom cultivation, prevention of drying of the culture medium and maintenance of an appropriate water content are important issues for the growth of mycelia. Coniferous tree bran has a large surface area and relatively high water retention capacity due to the powder. Therefore, we investigated the water retention capacity of wood bran for fine-grained charcoal. A medium consisting only of wood bran,
About water retention by the medium which mixed the wood bran and the fine coal,
There are reports of mushroom cultivation research conducted by public testing laboratories comparing the degree of difference. In this report, it was found that wood bran also had water retention equal to that of pulverized coal. On the other hand, coniferous tree bran, which has a large amount of ligulin and tree oil such as pine and cedar, has a property that it is hard to rot for a long time even if it is discarded in the open-air after mushroom cultivation and piled up in the field,
Composting takes several years, causing open-air pollution,
Mushroom farmers are worried.

[0008] As understood from these, coniferous tree bran has a combined effect such as water retention, immortalization and bactericidal effect of phytoncide. In particular, hinoki, hiba and cedar are preferably excellent in antibacterial activity. By making use of this combined effect, it becomes an antibacterial moisture conditioner that is less expensive than charcoal. However, there is a danger of decay when long-term use of over-moisture wood bran. Therefore, the wood bran is mixed with a porous substance so as not to be immortalized, and is controlled to be equal to or less than the upper limit of immortal water content. Therefore, as a general-purpose use method, an antibacterial humidity control material, which is a mixture of a processed softwood and a porous material, is used. As a processed product of softwood, a wood bran, its essential oil, and a mixture of the wood bran and its essential oil having a moisture controlling effect and an antibacterial effect are used. In particular, Kinukan,
As the essential oil, hinoki, hiba and cedar having antibacterial activity are preferable. As the porous material, fine-grained plant charcoal such as charcoal, firgar charcoal, mushroom waste sawdust and the like are used. Or perlite,
Use fine-grained porous minerals such as zeolite and diatomaceous earth. The mixing ratio of wood bran to the porous material is set to 10 to 50% by volume. Preferably, it is around 20%.
The mixing ratio of the essential oil to the porous substance may be about 1% by weight. This mixture is an antibacterial moisture conditioning material characterized by being laid under the floor in the state of roses, or
It is a building material for antibacterial humidity control characterized by being housed in a non-woven fabric bag and laid between floors and joists under the floor.

[0009] A second aspect of the present invention is to remove harmful gas generated from new building materials in a house, to suppress the generation of mold and ticks in an over-humid environment, and to treat respiratory diseases caused by an over-dry environment. A panel for antibacterial humidity control, characterized in that it contains a mixture of a coniferous processed product that has a preventive effect of phytoncide and a relaxing effect on the human body by the tree phytoncide, and a porous substance that prevents the coniferous processed product from becoming stuffy. In the wood.

[0010] As a kind of conifer, hinoki, hiba and cedar having excellent antibacterial activity are particularly desirable. The processed material of the conifer is preferably made of wood bran produced by a sawmill. Alternatively, an essential oil obtained by carbonizing and refining this wood bran may be used. Cypress,
The fragrance of hiba and the like has the function of strongly preventing the reproduction of mites, which cause allergies. Dermatophagoides and dust mites increase 100 times a month on human dandruff and red mosquitoes and cause allergies to sensoku and rash. If mites are placed in cypress or kiba tree bran, they die in one day. Also, it has been reported by the Forestry Research Institute that only 1% of the essential oil extracted from the tree bran was sprinkled, and no mites were found after 6 days.

[0011] An antibacterial humidity control panel characterized in that a mixture of a softwood processed product and a porous material is packed in a honeycomb placed on a base plate, covered with a nonwoven fabric, and the honeycomb is sandwiched between porous upper plates and sewn with synthetic fibers. Material. As the processed product of the conifer, it is preferable to use wood bran, its essential oil, or a mixture of wood bran and essential oil. In particular, hinoki, hiba, and cedar having excellent antibacterial activity are desirable. The material of the honeycomb may be ordinary strength pulp paper or aluminum. The shape of the honeycomb is not particularly limited, but is preferably a hexagonal honeycomb. The nonwoven fabric on the back surface of the porous upper plate prevents the wood bran and the porous substance packed in the honeycomb from the plate holes from spilling.
The base plate and the upper plate are preferably made of a wooden board such as a passing board. As the porous material, fine-grained plant charcoal such as charcoal, firgar charcoal, mushroom waste sawdust and the like are used. Alternatively, fine-grained porous minerals such as pearlite, zeolite, and diatomaceous earth are used. The mixing ratio of the wood bran to the porous substance is 10 to 50% by volume. Preferably, it is around 20%.
The mixing ratio of the essential oil to the porous material is 1% by weight.
Before and after. Accordingly, the panel material for antibacterial humidity control has a combined effect of the antibacterial effect of phytoncide of wood bran, the humidity control effect of the porous substance, and the immortal effect of wood bran due to the humidity control effect.

More specifically, in recent years, highly insulated and airtight houses have adopted an active system which has an energy saving function and forcibly ventilates room air with the outside air. Large amounts of carbon dioxide are generated. For this reason, there is a concern about global warming, and a passive system that does not use electricity has been used. Thus, natural wood decorative boards have been employed as much as possible on the inner wall of the room, and the function of the wood to absorb and release moisture naturally has been attempted to avoid the above problems, but it has not been sufficient. In particular, harmful gases such as formaldehyde and ammonia generated from the adhesive are trapped in the room, causing eye pain and allergic symptoms. Also, the air humidity in the room is too dry, causing respiratory disorders. In addition, if the air humidity in the room becomes excessive, ticks and molds occur, which causes allergic symptoms. As a measure against mites that occur on tatami mats,
Organophosphate pesticides have been used, but pose a significant problem of inhaling from the respiratory system as infants advance their prostheses.

As a countermeasure, various problems can be solved by using the antibacterial humidity control panel material of the present invention for a wall material of a room or a core material of a folding room. When the room is over-humidified, the excess humidity contained in the air is adsorbed on the porous material through the holes in the upper plate of the antibacterial humidity control material, and the humidity of the room is maintained at an appropriate level. When the room is over-dried, the insufficient humidity is supplied from the porous material through the holes in the upper plate of the antibacterial humidity control material, and the humidity of the room is appropriately maintained. However, porous materials such as vegetable charcoal and porous minerals have little antibacterial effect. Therefore, a porous substance mixed with coniferous tree bran and essential oil such as hinoki and cypress is used. Controls the disinfection and generation of molds and ticks on walls and folds. In addition, molds and mites that are alive in the porous material are also suppressed. Tatami with rice straw as core material,
It has an ecosystem in which the number of red mites and the number of house dust mites that feed on the mites are increased by feeding on sugar contained in rice straw. As the humidity in the room increases, the number of mites increases rapidly. In a closed house that has been absent for a long period of time, blue mold can grow abnormally on the surface of tatami mats using the nutrients of rush.
Furthermore, by releasing phytoncide, a coniferous tree component, into a room, the antibacterial humidity control panel material has a synergistic effect of creating a comfortable living environment with a relaxing effect.

[0014] A third aspect of the present invention is to provide a long-term freshness maintaining material for agricultural products required for storage of agricultural products, a processed product of softwood having a bactericidal effect on rot fungi of agricultural products by conifer phytoncide, and a freshness maintenance of agricultural products. A panel material for antibacterial humidity control, characterized in that it is a mixture with a porous substance having a combined effect such as an ethylene gas adsorption effect, a humidity control effect, and an effect of preventing stuffiness of a softwood processed product.

As a kind of softwood, cypress and cypress which are excellent in antibacterial activity are desirable. The processed product of the conifer is a wood bran produced from a conifer using a sawdust manufacturing machine. An essential oil obtained by carbonizing and refining this wood bran may be used. Cypress, Hiba tree bran and essential oil
It has the effect of preventing the propagation of putrefactive bacteria on agricultural products and sterilizing it.

[0016] An antibacterial effect, characterized in that a honeycomb placed on a porous lower plate is filled with a mixture of coniferous tree bran or its essential oil and a porous substance, covered with a nonwoven fabric, sandwiched between porous upper plates, and sewn with synthetic fibers. It is a wet panel material. The material of the honeycomb may be ordinary strength pulp paper or aluminum. The shape of the honeycomb is not particularly limited, but is preferably a hexagonal honeycomb. The nonwoven fabric on the back surface of the porous upper plate prevents the wood bran and the porous substance packed in the honeycomb from the plate holes from spilling. The base plate and upper plate are made of
A wood board such as a passing board is preferred. The porous material is
Fine-grained plant charcoal of 5 mm or less such as charcoal, fir charcoal, mushroom waste sawdust, or fine-grained porous mineral of 5 mm or less such as perlite, zeolite, or diatomaceous earth is used. The mixing ratio of wood bran to the porous material is 10 to 50 in volume ratio.
%, Preferably around 20%. The mixing ratio of the essential oil to the porous substance may be around 1% by weight.
Thereby, long-term freshness of agricultural products can be maintained due to the sterilizing effect of phytoncide, which is a tree component, and the moisture control effect of tree bran, which is immortalized by the moisture absorbing and releasing power of the porous substance.

More specifically, in recent years, low-temperature refrigerated storage has become widespread in the storage of agricultural products, and shipping is aimed at high prices. For long-term storage, it is important to suppress the metabolism of crops. In order to maintain long-term freshness, it is stored in low-temperature refrigeration to adjust the concentration of oxygen and carbon dioxide that suppress metabolism, and to remove ethylene gas that causes quality deterioration. Therefore, in a small low-temperature refrigerator, containers containing agricultural products are stacked and stored on a sawboard. Zeolite or charcoal powder paper for the purpose of adjusting the oxygen concentration and carbon dioxide concentration and removing ethylene gas is put in a plastic bag together with agricultural products and sealed. However, packing agricultural products in plastic bags one by one was troublesome and labor saving was desired. Further, large-scale storage for storing grains such as rice is troublesome and does not use a freshness preserving agent.

As a countermeasure, various problems can be solved by using the panel material for antibacterial humidity control of the present invention for a wall material, a pallet, and a sawboard of an agricultural product storage. When the humidity in the storage is too low, the produce is dry.
Therefore, in the storage using the antibacterial humidity control material of the present invention, the insufficient humidity is supplemented from the porous material through the holes of the upper and lower plates of the antibacterial humidity control material, and the humidity of the storage is appropriately maintained. Other functions of the porous material include an effect of preventing quality deterioration due to adsorption of ethylene gas and an effect of maintaining the freshness of agricultural products by suppressing metabolism by appropriately adsorbing carbon dioxide and oxygen. However, since the porous material has a weak antibacterial effect, coniferous tree bran such as hinoki and hiba, its essential oil, and a mixture of the tree bran and the essential oil are used. By using a mixture of a coniferous processed product and a porous material, it has a labor-saving and synergistic long-term freshness preserving effect capable of sterilizing and suppressing spoilage germs occurring in agricultural products. It is a panel material for antibacterial humidity control.
