[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a house humidity conditioning material, and more particularly to a house humidity conditioning material having a humidity conditioning function and a deodorizing function and used under the floor or behind the ceiling.
[0002]
[Problems to be solved by the invention]
In Japan, the temperature and humidity vary greatly with the seasons, with high temperatures and humidity in summer and low temperatures and low humidity in winter. In particular, the rainy season is a very unpleasant season for humans, but there are also problems for houses. In other words, during the rainy season, it is rainy and humid, so that the under floor gets wet, the house structural material rots, and white ants are damaged. For this reason, various measures have been taken to prevent the floor from getting wet. For example, improving the ventilation under the floor, laying concrete under the floor, laying ant-proof sheets under the floor, and the like have been performed.
[0003]
However, the lower the floor, the better. If the underfloor dries, not only will the indoor humidity be affected, the habitability will deteriorate, but also the structural materials that make up the house, especially wood such as pillars and wallboards, will be deformed and cracked. Therefore, it is desirable that the underfloor is neither high humidity nor dry, and is adjusted to an appropriate humidity.
[0004]
Conventionally, charcoal has been laid to reduce the humidity under the floor. Charcoal has a deodorizing function as well as a hygroscopic function, and is an excellent material as a hygroscopic material. However, charcoal has a relatively small amount of moisture absorption and a poor moisture-releasing function, so that there are problems such as insufficient respiration for adjusting humidity.
[0005]
It is also important to adjust indoor humidity as well as under-floor humidity. When the indoor humidity is high, not only is it uncomfortable for residents, but there is also a problem that mites and molds are generated. On the other hand, if the humidity is too low, there are problems that the body becomes dry and hurts the throat, the skin becomes rustled, and it is easy to catch a cold. Therefore, it is desirable that the indoors be adjusted to an appropriate humidity.
[0006]
For such indoor humidity adjustment, a method of adjusting humidity by an air conditioner, a humidifier, a dehumidifier, or the like has been adopted. However, there are many people who do not match the constitution with the artificial adjustment method, and a gentle adjustment method similar to the natural environment is expected.
[0007]
However, in recent years, the degree of sealing has increased in order to increase the efficiency of air conditioning, and natural ventilation has become increasingly difficult. In addition, with the development of new building materials, the generation of volatile components harmful to the body has become a problem, and the development of a method for removing these harmful volatile components is also important.
[0008]
Therefore, the present inventor has arrived at the present invention as a result of earnest study on a house humidity control material having a humidity control function and an adsorption / deodorization function.
[0009]
The present invention takes the following means to solve the above problems. That is, the house moisture conditioner according to the present invention is a humidity conditioner composed of 10 to 90 parts by weight of expanded obsidian and 90 to 10 parts of charcoal , and the expanded obsidian and the charcoal have a diameter or 1 The side length is 3 mm or more and 5 cm or less.
[0010]
Next, the house moisture conditioner according to the present invention is characterized in that the expanded obsidian and the charcoal have a diameter or a side length of 1 cm or more and 3 cm or less.
[0011]
Moreover, in this house humidity conditioning material, the said humidity conditioning material exists in being wrapped with the air-permeable and water-impermeable sheet-like material.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The purpose of the house moisture-conditioning material according to the present invention is to fully utilize each other's advantages by combining charcoal with moisture absorption / deodorization function and expanded obsidian with excellent moisture absorption / moisture release function. . That is, the charcoal alone has a poor moisture release function, so that the humidity control action is insufficient, and the expanded obsidian alone does not have an adsorption / deodorization function, so that a clean atmosphere cannot be obtained. By combining the two, it is possible to obtain a house humidity conditioning material having a humidity control function and a deodorizing function.
[0013]
Here, the expanded obsidian referred to in the present invention means a product obtained by firing and expanding obsidian to reduce the weight and weight, and is called so-called pearlite. The expanded obsidian is preferably a material whose apparent specific gravity is 0.3 to 0.6 and whose bulk density is reduced to about 0.1.
[0014]
It is also called pearlite, and there is a porous weight-reduced product fired from pearlite, but it is not preferable to use it in the present invention because of its poor moisture release function. Zeolite is a humidity control material that has an excellent moisture absorption and moisture release function, but its specific gravity is larger than that of expanded obsidian, so its use is limited and it is not preferable to use it in the present invention. Only by the combination of expanded obsidian and charcoal, it is possible to construct a house moisture conditioning material having the most preferable light weight, humidity conditioning function and deodorizing function.
[0015]
The charcoal means a carbide baked from wood, bamboo, rice husks, etc., and its raw material is not particularly limited. However, charcoal using wood as a raw material is preferable because of its excellent moisture absorption and deodorizing function. Charcoal has various forms of raw materials such as those obtained by firing and pulverizing thinned wood, and those obtained by firing crushed wood scraps, and are not limited.
[0016]
The house moisture conditioner of the present invention is composed of 10 to 90 parts by weight of expanded obsidian and 90 to 10 parts by weight of charcoal, and a ratio of about 70% by weight of expanded obsidian and about 30% by weight of charcoal is particularly preferred. The apparent specific gravity of charcoal is about 0.4 to 1.2, which is larger than the apparent specific gravity of expanded obsidian, so that the composition ratio by volume is smaller for charcoal than for the above weight ratio. If the expanded obsidian is less than 10 parts by weight, the humidity control function is insufficient, and if the charcoal is less than 10 parts by weight, the deodorizing function is insufficient. The expanded obsidian and charcoal may be stacked in layers, but work is easier if they are mixed and laid.
[0017]
The expanded obsidian and charcoal are used in the form of a granule or lump having a diameter or length of about 3 mm to 5 cm, and more preferably about 1 cm to 3 cm. In order to mix uniformly, it is good to make the particle size of both into about the same magnitude | size. When the particle size is about 3 mm or less, the air permeability is deteriorated, and when the particle size is about 5 cm or more, the surface area becomes small and the humidity control / deodorizing function is lowered.
[0018]
The use place of the house moisture-conditioning material of the present invention can be used both outdoors, such as under the floor, and indoors, such as inside a closet or behind a ceiling, and is not particularly limited. When laid under the floor, its excellent humidity control function can remove moisture under the floor, prevent decay of house structural materials and damage by white ants, and maintain proper humidity, so that deformation and cracking of wood can be prevented. Can be prevented. In addition, when used indoors, it can prevent the occurrence of mites and molds, and the humidity is adjusted naturally and gently, making it an ideal environment for the human body, increasing resistance to colds and the skin and throat. Drying can be prevented.
[0019]
As mentioned above, although the embodiment of the house humidity control material which concerns on this invention was described, this invention is not limited to the above-mentioned form.
[0020]
For example, the house humidity conditioner according to the present invention can be configured as a house humidity conditioner used for the ceiling. In other words, it is an effective means to lay a humidity control material on the back of the ceiling in order to control the humidity of the entire interior. However, if the humidity control material is heavy, the structure of the house must be reinforced and the economic burden is increased. large. The expanded obsidian has a bulk density of 0.1 and is very lightweight, so there is no need to consider the structure of the house. In addition, since the expanded obsidian is a humidity control material as well as a heat insulating material, laying the expanded obsidian on the back of the ceiling can provide an effect that is useful for heat insulation in the room. Conventionally, it can function as an alternative or supplement to heat insulation that has been performed with glass wool or the like.
[0021]
As the house moisture conditioner used for the ceiling, expanded obsidian may be used alone or together with charcoal or the like. By using charcoal in a mixed manner, various odors or harmful gases generated from the building materials of the house, odor of excrement such as firewood, etc. can be removed by the deodorizing function of charcoal.
[0022]
The house moisture-conditioning material according to the present invention may be laid directly, for example, by spraying it under the floor or under the ceiling, but it is preferably wrapped in a breathable sheet and used as a mat or cushion. If it is not wrapped in a sheet, the transportation is very troublesome and the workability during construction is poor. In addition, when laying outdoors under the floor or the like, the expanded obsidian is light and may be blown off by the wind, which is not preferable.
[0023]
In particular, it is possible to wrap the humidity control material in a breathable and non-water-permeable sheet to improve workability during transportation and construction, and to more efficiently express the functions of humidity control and deodorization. Breathability is a necessary property for the purposes of the present invention. There are two effects obtained due to the non-water permeability. One point, especially when used outdoors, such as under the floor, even when the mat-like material containing the humidity control material gets wet with water, the humidity control material inside is prevented from getting wet, and the moisture absorption function is quickly restored. There is to make it. In addition, it cannot be overemphasized that water | moisture content, such as water vapor | steam contained in air, can pass through with the water-impermeable sheet here.
[0024]
Another point is to prevent the fine powder of the humidity control material from slipping out of the mat-like material. Expanded obsidian is very light and brittle, so it collapses to a fine powder with a slight force. In addition, charcoal is also relatively soft and easily crushed and easily becomes a fine powder. Therefore, when a mat-like material is formed by wrapping it in a sheet, even if it is about 3 mm to 5 cm in size, fine powder may be generated during storage or transportation, and measures must be taken. It becomes. In particular, the charcoal fine powder is black and stains the surroundings, so a sufficient measure is necessary. The air-permeable and non-water-permeable sheet-like material does not have a large hole through which fine powder can escape, so that the above object can be sufficiently achieved.
[0025]
Various commercially available sheets can be used as the air-permeable and water-impermeable sheet material. That is, a fine woven fabric, a film having fine holes, a non-woven fabric, a laminate thereof, or the like can be used for the air-permeable and water-impermeable sheet-like material. Of these, non-woven fabrics are preferred, and so-called spunbond nonwoven fabrics, flash spinning nonwoven fabrics, melt blown nonwoven fabrics, and the like are suitable. These nonwoven fabrics are preferable because they are excellent in physical properties such as flexibility, air permeability and toughness, and are relatively inexpensive.
[0026]
FIG. 1 shows an example of a usage state of a house humidity control material according to the present invention. A floor mat 12 is laid under the floor 10 and a ceiling mat 22 is laid under the ceiling 20. FIG. 2 schematically shows how the underfloor mat 12 is laid.
[0027]
In addition, the present invention is carried out in a mode in which various improvements, corrections, and modifications are added based on the knowledge of those skilled in the art, such as the properties of expanded obsidian and charcoal, the packaging form of the humidity control material, and the like without departing from the spirit of the present invention. To get.
[0028]
Examples of the present invention are described in detail below.
[0029]
Example 1 A house moisture conditioner was manufactured by mixing 70 parts by weight of expanded obsidian and 30 parts by weight of charcoal. The expanded obsidian had a bulk density of 0.1, the charcoal had a bulk density of 0.5, and each particle size was about 1 cm to 2 cm. Houses tone Shimezai 18 liters of this example, 50 cm × 50 cm of the nonwoven fabric (trade name UniCel® BT2109W 70 g, material polyethylene, manufactured by Teijin Ltd.) packed in a bag made of, as shown in Figure 2, the 4 bags per 1 m ² Laying under the floor at a rate. As a result, the humidity under the floor decreased and no white ants were observed.
[0030]
Second Example 14 liters of house moisture-conditioning material used in the first example was packed in a 40 cm × 40 cm bag and laid on the back of the ceiling at a rate of 6 bags per 1 m ² . As a result, changes in indoor temperature and humidity decreased throughout the year, improving comfortability.
[0031]
Third Example The house moisture-conditioning material used in the second example was packed in a 80 cm × 170 cm mat-like bag with a thickness of 3 cm, and was used by putting it in a close-in width. As a result, moisture in the closet was reduced and odor was eliminated.
[0032]
【The invention's effect】
According to the house moisture-conditioning material of the present invention, the hygroscopic / moisture-releasing function of expanded obsidian and the hygroscopic / adsorption / deodorizing function of charcoal act synergistically. For this reason, when used outdoors such as under the floor, the structure of the house can be prevented from being rotted and white ant damage can be prevented from occurring. In addition, when used indoors such as in closets and ceilings, generation of mites and molds can be suppressed, and comfort is improved because the humidity is adjusted to a natural and comfortable humidity.
[0033]
Furthermore, according to the usage that uses a house moisture-conditioning material for the ceiling, in addition to the effects of humidity adjustment, deodorization, and removal of harmful gases in the house, the house-conditioning material functions as a heat insulating material. The heat insulation and heat insulation effect can be improved, and the utility cost associated with air conditioning can be reduced.
[0034]
Moreover, the effect which improves workability | operativity of conveyance and construction is acquired by wrapping a house moisture-conditioning material with a breathable and non-water-permeable sheet. In addition, since the humidity control material of the house does not get wet with water, an effect of stabilizing the humidity control function can be obtained, and further, an effect of preventing the fine particles of expanded obsidian and charcoal from spilling out and soiling the surroundings can be obtained.
