Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for fumigating a cultural property with an alkyl iodide-containing fumigant for achieving protection of a cultural property while contributing to environmental protection with a fumigant with less ozone layer destruction. About.

[0002]

2. Description of the Related Art The preservation and utilization of cultural properties contributes to the cultural improvement of the people and contributes to the progress of world culture. Cultural assets that are paintings, sculptures, crafts, titles, ancient documents, and other tangible cultural products include the National Museum of Modern Art, the National Museum of Western Art, the National Institute for Japanese Language, the Japanese Art Academy, the National Museums of Tokyo, Kyoto, and Nara, Fumigation for insect repellent and fungicide is performed at various places such as the National Research Institute for Cultural Properties in Tokyo and Nara as part of its preservation and maintenance work.

[0003] Considering the properties of cultural properties, fumigants do not cause harm to cultural properties, are not adsorbed on cultural properties, have excellent diffusion and permeability, have low flammable explosive properties, adult pests, pupae. It is necessary to satisfy requirements such as the effect on larvae and eggs, that is, strong insecticidal activity and low toxicity to humans and animals.In Japan, methyl bromide / ethylene oxide combination, carbon disulfide, hydrocyanic acid, Hydrogen phosphide, chloropicrin, methyl bromide, carbon tetrachloride, ethylene oxide and the like have been used. Among them, a mixture of methyl bromide and ethylene oxide is particularly widely used because of its excellent insecticidal and bactericidal effects.

In recent years, however, methyl bromide has been cited as a substance causing ozone layer depletion, and its use has been restricted.

On the other hand, US Pat. No. 5,518,692 discloses that methyl iodide can be used as a soil fumigant as a substitute for methyl bromide. Both bromine and iodine are halogen compounds, but the rate at which iodide reaches the ozone layer is because iodide is more unstable than bromide and most of the iodide is absorbed by seawater and quickly disappears from the atmosphere. And the ozone depletion ability is extremely low.

[0006] However, methyl iodide is originally a methylating agent, and is used as a raw material for synthesizing pharmaceuticals and agricultural chemicals.
It is a compound with extremely high reactivity. When used as a soil fumigant, the effect of the fumigant on the soil itself is not a problem, but it is problematic for use as a cultural property. That is,
The purpose of fumigation of cultural properties is to prevent fungi and insects, but the purpose is to preserve and preserve the cultural properties themselves for posterity.
Therefore, the impact on cultural properties itself is of paramount importance.
However, this publication only discloses a bactericidal action and an insecticidal action when methyl iodide is fumigated into soil, and does not evaluate the effect on soil itself.

Further, the soil has a humidity of 5.85% to 32%.
In general, cultural properties are stored at a humidity of 50 to 70% while the humidity is extremely low. This is because lacquerware cracks when the humidity is low, so that careful control of humidity is required. On the other hand, since methyl iodide has a higher boiling point than methyl bromide, it is difficult to vaporize and is absorbed in moisture. Therefore, in a cultural property protection environment, methyl iodide itself may be a cause of contamination of cultural properties due to its physical properties in addition to the chemical reactivity of methyl iodide. In this regard, in the case of soil fumigation, coloring of the soil with a fumigant is unlikely to be a problem, which is different from the use for cultural properties in which slight coloring contamination is not allowed. However, in the above publication, it is completely unknown how the alkyl iodide affects the cultural property under high humidity for the cultural property protection environment.

[0008] Further, since soil and cultural properties have different materials, molds and insects generated on these soils generally differ naturally. For this reason, the effect of methyl iodide on molds and insects generated on cultural properties is completely unknown from the above publication. In particular, cultural assets include cloth, paper, wood, metal, etc.
Often composed of different materials. Therefore,
Selection of fumigants for cultural properties should be used unless the physical and chemical reactivity of the fumigants, as well as the type of fungi and insects to be targeted, is actually evaluated for the target cultural properties Cannot be done.

In addition, from the viewpoint of environmental protection, it is not preferable to release such a substance into the atmosphere after use such as fumigation treatment. Therefore, there is a demand for a method of fumigating a cultural property with the use of a fumigant as small as possible while keeping the viewpoint of environmental protection and cultural property protection in mind.

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to control humidity and temperature as needed, minimize damage to cultural properties, and reliably increase the fumigation effect with a small amount of use. It is to provide a method of fumigation of cultural properties that can be done. In particular, the present invention provides a method for fumigating a cultural property which is excellent in germicidal and insecticidal effects without destroying the ozone layer and is suitable for maintaining and protecting the cultural property itself, from the viewpoints of environmental protection and protection of cultural properties.

[0023]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is characterized in that a cultural property is housed in an isolated container and fumigated with a fumigant containing alkyl iodide. In general, alkyl halides are considered to have a bimolecular nucleophilic substitution reaction on NH ₂ groups and SH groups in amino acids and peptides contained in organisms, and to exert a biocidal effect. On the other hand, since alkyl iodide itself is used as an alkylating agent, its reactivity is extremely high, and there is a concern that the quality of the cultural property itself may be altered. In this environment, we conducted detailed investigations on the reactivity, biocidal properties, and environmental impact of using alkyl iodide as a fumigant in a cultural property protection environment. It has been found that fumigation with alkyl does not cause discoloration or deterioration of cultural properties, and has a broader and stronger antibacterial effect than the conventional product methyl bromide. As a result, the amount of ethylene oxide compounded for the purpose of sterilization can be reduced. Ethylene oxide requires advanced technology to avoid the danger to explosive people and cultural assets when used, and reducing the amount of ethylene oxide is an extremely excellent method for fumigating cultural assets. It can be said that it is a method. In addition, the amount of the alkyl iodide itself can be reduced because the alkyl iodide is excellent in biocidal properties. This can be said to be excellent from the viewpoint of environmental protection and cultural property protection. Furthermore, some cultural properties, such as lacquerware and paintings, are severely damaged by drying, and humidity control is indispensable. However, when cultural assets are stored in an isolated container and fumigated under the required temperature control, the cultural assets are not colored due to the reaction between moisture and alkyl iodide within the range of the amount used. It turned out to be excellent for cultural property protection. Hereinafter, the present invention will be described in detail.

The isolation container of the present invention is not particularly limited as long as it is a container in which the confidentiality of the fumigant is maintained during the fumigating treatment of the fumigant. Further, even if it is a container, it is only necessary to secure an isolated space in which the hermeticity of the fumigant is maintained. Therefore, when a fumigant is wrapped with a resin film or sheet so that the hermeticity is maintained (coated fumigation or wrapped fumigation), the cultural property is stored in a container created by laminating the resin film or sheet using an adhesive or the like. The case (closed fumigation) also corresponds to storage in an isolated container. further,
It may be a fumigation facility such as a chamber, a fumigation room, or a fumigation warehouse. From the viewpoint of fumigation preparation, it is preferable to use a chamber or a fumigation chamber. According to the present invention, the use of the isolated container in this manner can reduce the amount of the fumigant used, and further suppresses the release of the fumigant into the atmosphere and enables the recovery process. In addition, if the isolation container is equipped with a temperature and humidity control device, it is possible to fumigate cultural properties without considering changes in the weather, and to perform fumigation processing that matches the properties such as the material and size of cultural properties It becomes.

In the present invention, a fumigant containing an alkyl iodide is used. As the alkyl iodide, alkyl monoiodo having 1 to 4 carbon atoms, for example, methyl iodide, ethyl iodide, butyl iodide, and normal propyl iodide are preferable. These have relatively little action such as corrosion over the entire material used for cultural properties, have a certain biocidal effect, and have high volatility even at a boiling point or lower. It does not liquefy because of its excellent antibacterial properties than the conventional methyl bromide. Particularly preferred is methyl iodide. It is because it is more excellent in antibacterial property than methyl bromide and also excellent in insecticidal effect on black elephants. In the fumigant containing an alkyl iodide, the alkyl iodide contains 5-95 wt%, more preferably 10-90 wt%, and especially 15-85 wt%.
% Is preferably contained. This is because, in this range, the biocidal properties are particularly excellent, and the influence of alteration and corrosion on cultural properties is small.

In the present invention, in addition to using the alkyl iodide alone, other fungicides and insecticides can be used together with the alkyl iodide. Fungicides that can be used include ethylene oxide, propylene oxide, formaldehyde, glutaraldehyde, propionaldehyde, crotonaldehyde, acrolein, methacrolein, butyraldehyde, valeraldehyde, allyl alcohol, butyl alcohol, and hydrogen peroxide. These can be used in combination with the alkyl iodide, and the other bactericidal effects are not impaired by the combination. In the present invention, when one kind of these fungicides is used in combination, two or more kinds may be used in combination.

Further, in the present invention, the insecticide can be fumigated with the alkyl iodide. Examples of the insecticide include chlorpicrin, carbon disulfide, sulfuryl fluoride, methyl bromide and hydrocyanic acid. In the present invention, two or more of these can be used in combination with one of these.
In the present invention, among these insecticides, it is preferable to use sulfuryl fluoride and methyl bromide. They are,
This is because the impact on cultural properties is relatively small. In the present invention, one or more of the above-mentioned fungicides may be used in combination with one or more of the above-mentioned insecticides together with the alkyl iodide. This is because it is possible to fumigate a cultural property having an excellent insecticidal and bactericidal effect while paying attention to environmental conservation.

In the isolated container, the fumigation treatment is performed within a temperature range suitable for preserving the cultural property. However, while paying attention to the flammability of the gas components in the sterilization area, it is preferable to use a thick resin film or the like having a high heat retaining property. It is preferable to use a sheet or cover the sheet with a heat insulating material and use a temperature controller or a humidity controller. Therefore, the fumigation temperature can be appropriately selected depending on the target cultural property, but is preferably from 0 to 40 ° C, more preferably from 20 to 30 ° C.

The fumigant is preferably fumigated using a vaporizer. This is because it is suitable for vaporizing alkyl iodide and is effective for shortening the fumigation time. Also, when the alkyl iodide is a liquid, the alkyl iodide may directly contact the cultural property, which may lead to contamination of the cultural property. The fumigation time can be appropriately selected depending on the type of the target cultural property and the type of fumigant.
Time is enough.

In the fumigation, a mixture of an alkyl iodide and a bactericide or an insecticide is administered and used, and the alkyl iodide and the bactericide or the insecticide are separately administered in the same isolated container and sealed. May be used. In the present invention, the concentration of the alkyl iodide in the isolation container is 0.005 to 0.005.
It is preferably 1.5 mM / L, more preferably 0.02 to 1.0 mM / L, particularly 0.05 to 0.5 m / L.
M / L. The concentration of the fungicide is 0.005 to
It is preferably 1.5 mM / L, more preferably 0.02 to 1.0 mM / L, particularly 0.05 to 0.5 m / L.
M / L. The concentration of the insecticide is 0.005 to
It is preferably 1.5 mM / L, more preferably 0.02 to 1.0 mM / L, particularly 0.05 to 0.5 m / L.
M / L. Within this range, sufficient biocidal properties can be obtained, and there is little alteration or corrosion of cultural properties.
The fumigation concentration can be appropriately selected within the above range in consideration of the material of the target cultural property. This makes it possible to perform fumigation treatment that further prevents deterioration of cultural properties.

In the method for fumigating a cultural property of the present invention, the humidity can be selected in consideration of the characteristics of the cultural property. Therefore, when the cultural property is mainly metal, the humidity 60
%, The corrosion of the metal during the fumigation process can be prevented. On the other hand, for cultural properties that are vulnerable to drying, such as folding screens, scrolls, books, books, paper, lacquerware and paintings, shrinkage of cultural properties by fumigation at a humidity of 60 to 80%, more preferably 60 to 70%, Damage due to drying such as cracks can be prevented.

In the present invention, it is preferable that the cultural property to be fumigated is decomposed in advance for each constituent material, and the same material is subjected to fumigation treatment using a fumigant suitable for the material. In particular, for cultural properties, for example, even if a single piece of metal is used, the alloy composition differs depending on the place of excavation and the age of excavation, and the reactivity to the fumigation conditions used also differs. For this reason, the cultural properties, which are the objects of fumigation, are separated as much as possible, and those with the same reactivity to the fumigation process are collected and fumigated, thereby further preventing corrosion and alteration of the cultural properties. is there. As a result, the gloss, discoloration, corrosion,
This is because rust and the like can be suppressed as much as possible.

For example, for dyed products, a temperature of 15 to 22 ° C.
A humidity of 20 to 40% is preferred. Further, the temperature is preferably 20 to 24 ° C. and the humidity is 55% or less for metalwork.

In the present invention, the cultural property is a tangible cultural property specified in item 1 specified in Article 2 of the Cultural Property Protection Act and a folk cultural property specified in item 3, excluding buildings. Means something. Therefore, it can be generally used as a target of fumigation treatment of cultural properties. In particular,
