Description Humidifier and method of using the humectant

TECHNICAL FIELD The present invention relates to a humectant having an anti-termite action and a method for using the same. Background art

Shiroari damage to buildings has become a bigger problem than before. It is well known that people generally prefer to eat wet wood, but in addition to wood, cloth, paper, concrete, soil, rubber, and certain types of It has been known that plastic materials are also extremely omnivorous pests that are harmful or penetrate. Such damage is exacerbated worldwide, both in Japan and abroad, and in both wet and dry climates. As a countermeasure against whitening, synthetic chemicals and natural chemicals have been sprayed or applied under the floor, in the base concrete and surrounding soil, where soil nests are likely to form nests. However, such methods do not provide long-lasting effects on termites due to the volatility of each of the above-mentioned chemicals, and the chemicals are treated many times after a predetermined period of time. There is a problem that it is necessary and it is troublesome and costly, and some medicines are harmful to humans, pets, livestock, etc. Organic compounds may be contained, and such synthetic agents and the like may remain in soil and the like. In addition, the active ingredient may volatilize and diffuse into the room, which is an obstacle to sino and us.

On the other hand, a humid underfloor environment not only causes the growth of mold and other bacteria and the decay of wood, but also the growth of termites that feed on mold wood. . Therefore, a method has been adopted in which a humidity control agent is sprayed under the floor to keep the humidity under the floor appropriately dry and almost constant.

However, it is said that pests such as white mites and fungi such as mold are difficult to breed in buildings using wood such as Aomori Hiba and Taiwan Cypress. It has been found that the hinokitiol component contained in such wood has insect repellent and antibacterial effects. Therefore, a method to obtain the anti-whitening effect by spraying or applying the essential oil of hinokitiol or a liquid solution obtained by diluting it directly under the floor or the foundation of a building, etc. There are various thoughts. However, in such a method, the initial effect is weakened if the hinokitiol component volatilizes once after applying a treatment such as spraying a liquid agent, and then the treatment is repeated and repeated. There is a problem that must be performed. In addition, liquids generally need to be stored and transported in tanks, etc., and handling is inconvenient.

In general, porous particles such as powders of activated carbon, silica gel, natural ore, and the like are used as a humidity conditioner. They exert a humidity control action by adsorbing moisture to or releasing moisture from the pores that open to the surface. However, it is difficult to obtain a sufficient ant-controlling effect only by the humidity control effect of the humidity control agent sprayed under the floor.

That is, in order to properly control the humidity under the floor and termite control, the surrounding environment, residents and construction workers are not adversely affected, and the termite-control effect can be maintained for a long period of time. It would be desirable to take aggressive anti-termite measures and under-floor humidity control at the same time, but at present, only one of them has been implemented, and sufficient effects have been obtained. Hard to say

Under these circumstances, hinokitiol, which does not harm the human body, animals, and the environment, is effectively used, and the hinokitiol plays a repellent effect on the termites for a long time. There is a need for a humectant that can be used. Disclosure of the invention

In view of the above problems, an object of the present invention is to provide a humidity control agent having an effective termitic effect and a method for using the same.

That is, the humectant of the present invention is a mixture of mineral particles having a humidifying effect and porous ceramic particles having hinokitiol-containing liquid or hiba oil in the pores. It is characterized by the fact that it is the subject.

Therefore, this humectant can be applied to the soil under the floor and around buildings. By spraying, etc., the humidity under the floor and the like is kept almost constant by the mineral particles that have a humidity-controlling effect, preventing the growth of mold and the like, and preventing damage by white ants. Not only can create a safe environment, but also prevent the release of liquids and hiba oil contained in the porous ceramic particles due to the action of hinokitiol contained in them. It will be possible to take more thorough and active measures against ants. More specifically, ceramic particles are generally known to be porous, and various substances are irrespective of water-soluble substances or oil-soluble substances in the pores. It has the property of adsorbing. Focusing on the use of such ceramics as a carrier, by holding a liquid containing hinokitiol in the pores, the adsorbed hinokitiol can be used in the pores. If it evaporates gradually, the repellent effect, especially on termites, will be obtained over a long period of time. Here, as the hinokitiol, a liquid agent extracted from wood such as Aomori Hiba or Taiwan hinoki, a solution of chemically synthesized hinokitiol, or the like can be used. In order to more easily obtain the effect of hinokitiol, it is also possible to make the pores of the ceramic particles hold the hiba oil. In this way, since Hiba oil contains a large amount of Hinokitiol, the above-mentioned effects such as antibacterial, antibacterial, and insect repelling effects of Hinokitiol can be obtained. The hinokitiol extraction process can be eliminated, reducing the cost and time involved in producing these ceramic particles. can do.

Ores suitable for use in such humidifiers are generally based on silicon dioxide, but porous ores, particularly those containing calcium borate, are preferred. Combined with the action of hinokitiol released from the wax particles, the termite-controlling effect can be further improved. Examples of the calcium borate-containing mineral include colemanite, which is an ore calculated naturally. Cholemanite contains calcium borate in a relatively high amount as a hydrate, and has a killing effect on the body due to the action of calcium borate dissolved by alcohol secreted outside by the body. Since it exerts its effects, it is also suitable for use as a termiticide. In other words, even after all the hinokitiol held by the porous ceramic particles is released, calcium borate having an anti-termitic effect remains in the colemanite, so that the high siroa for an extremely long period of time. Re-control effect can be expected. On the other hand, the porous ceramic particles that have completely released hinokitiol function as a suitable humectant, so that the humidifying effect as a whole does not decrease. However, considering the concentration of calcium borate remaining in the soil and the safety, it is preferable that the calcium borate component be contained in the range of lmg / l or less.

In addition, as the ore particles, those mainly composed of diatomaceous earth particles can be used relatively easily at a relatively low cost and have excellent humidity control action. On the other hand, the porous ceramic particles are in a state in which a liquid containing hinokitiol or hiba oil is adsorbed in the pores thereof, but the porous ceramic particles are aggregated. Even if the microcapsule capable of gradually releasing the hiba oil is constituted by the outer shell formed and the hiba oil contained in the internal space surrounded by the outer shell, Good. In such a case, the liquid containing hinokitiol or hiba oil inside the microcapsules passes through the pores of the respective porous ceramic particles or a gap between the porous ceramic particles. The hinokitiol release period can be prolonged because it is gradually released to the outside. In order to maintain a certain level of quality, it is appropriate for the porous ceramic particles to use artificial ceramic particles mainly composed of high-purity ceramics.

In order to obtain the above effects sufficiently and to be inexpensive in terms of cost, the porous ceramic particles and the mineral particles must be mixed in a ratio of 1: 9. To 5: 5 in a mixing ratio. The ratio other than the above ratio can be appropriately changed depending on the place where such a humidity control agent is applied.

As a method for appropriately controlling the humidity and termites of a building using the above-mentioned humidity control agent, the method of casting the foundation concrete part of the building is as follows. Another example is a method of using a humectant mixed in the soil underlying the base concrete part. On the other hand, considering the above-mentioned humectant from other aspects, it is considered that the ceramic particles having a liquid containing hinokitiol or hiba oil in the pores and calcium borate-containing particles It can also be called a termite control agent characterized by being mixed with mineral powder. Therefore, according to the present invention, for example, before the foundation concrete part of the building is cast, if the method of use mixed into the soil which is the base of the foundation concrete part is carried out, It is possible to obtain the effect of the other while at the same time aiming at either humidity control or termite control.

As described above, the humidity control agent of the present invention is a mixture of novel ceramic particles having a liquid containing hiba oil or hinokitiol in the pores and mineral particles having a humidity control action. It is composed mainly of. Thus, the combined use of the mineral particles and the ceramic particles, together with the effect of hinokitiol, which is retained and continuously released by the ceramic particles, provides a long-term effect. It can be expected to have a high humidity control effect over a long period of time and a control effect on termites. In particular, if colemanite or the like containing calcium borate is used as the mineral particles, the termite-controlling effect can be further improved. In addition, such a humidifier can be mixed into the soil underneath the base concrete section before casting the base concrete section of the building. The work produces not only a high humidity control effect, but also a repellent effect. BRIEF DESCRIPTION OF THE FIGURES

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The humidifier 1 in the present embodiment is mainly composed of a mixture of ceramic particles 11 described below and a powder of a calcium borate-containing mineral (hereinafter, referred to as “collemanate”; not shown). is there.

As shown in a schematic cross-sectional view of FIG. 1, the ceramic particles 11 contain hiba oil 12 in the pores 11a thereof. As shown in the figure, each of the ceramic particles 11 has an average particle size of about 7 micrometer, and the pores 11 are innumerable micropores. These are super-porous fine particles having a. For example, a predetermined amount of the ceramic particles 11 is put into a container in which the hiba oil 12 is stored, and the hiba oil 12 is adsorbed in the pores 11 a. It is manufactured by drying the Hiba oil 12 to such an extent that it does not evaporate. Alternatively, by using a general microcapsule manufacturing apparatus and spraying Hiba oil 12 and ceramic particles 11 inside the vacuum apparatus, for example, a schematic diagram shown in FIG. As shown in the cross-sectional view, it is possible to produce a microcapsule 10 containing an aggregate of a large number of ceramic particles 11 as an outer shell and containing hiba oil 12 therein. In such a microcapsule 10, the hiba oil 12 is released to the outside through the pores 11 a of the ceramic particles 11, or the hiba oil 12 is released through the gap between the ceramic particles 11. It has the function of releasing oil 12 to the outside. Therefore, ceramic particles 11 having Hiba oil 12 adsorbed in the pores may be used as such, or microcapsules 10 containing Hino oil 12 inside may be used. (Hiba oil 12 is a liquid obtained by applying high-temperature, high-pressure steam to finely ground wood chips, bark, branches and leaves, etc. of Aomori Hiba and Taiwan cypress. In this embodiment, for example, an acidic oil, which is an oily component obtained by steam extraction of Aomori Hiba wood chips and branches and leaves containing a large amount of hinokitiol, is used. Hiba oil 1 obtained in this way contains toroborones, which are 7-membered cyclic compounds unique to the Cypress family, and among them, especially against white clover. high repellent effect Te. component der having Ru a mounting Kichioru (C ₁₀ H ₁₂ O ₂₎ Beauty that is analogue / 3 - quality of about 2% content of the de la yellowtail down (C ₁₀ H ₁₀ 〇 ₂₎ It uses something that is almost constant and stable.

In addition, the colemanite powder is obtained by crushing the collected natural colemanate, and in this case, taking into account the residual amount of calcium borate in the soil and the safety in health. In addition, the one containing calcium borate in the range of 1 mg Zl or less shall be used.

Here, the test for the effect of preventing ceramics particles 11 from siroily effect and the results thereof will be described with reference to FIGS. 2 and 3. FIG. This test complies with the Japan Wood Preservation Association Standard No. 13 (1992) “Method for testing the effectiveness of termites for soil treatment and laboratory tests for performance criteria (1)”. It does. Hereinafter, the test method will be briefly described. As shown in Fig. 3, two test tubes TT1 and TT2 with glass branches are placed with their branches facing each other, and a glass tube GT with both ends opened is inserted between the branches. . The sample X is placed in the glass tube GT, and the sample is scaled from 0 to 5 at regular intervals of about 1 cm in the longitudinal direction of the glass tube from one side (the right side in the illustrated example) in order. The test tube TT 1 on one side (right side in the illustrated example) contains a predetermined number of silliaries (not shown) together with untreated soil Y, and the test tube on the other side (left side in the same example). Tube TT 2 contains scotch shards Z, which is used as a diet for shirori. The upper ends of both test tubes are covered with perforated aluminum foil TTa. That is, in this test, after elapse of a predetermined time at a predetermined temperature, the termite was removed from the test tube TT1 by a pine shredder Z. The purpose of this study is to determine the scale at which the sample X can be advanced in order to eat food.

In this test, seven test categories A to G were set as sample X, and three tests were performed for each test category. Figure 4 (a) shows the contents of sample X in each test category. Specifically, each sample X was placed in a glass tube GT, with 100% ceramic particles 11 in test category A and 40% ceramic particles 11 in test zone B. And Colemanite: 60%, Test Category C: 20% ceramic particles 11 and Colemanite: 80%, Test Category D: Colemanite: 100%, Test Category In E, 20% of ceramic particles 11 and 80% of sandy loam, and in test category F, 100% of sandy loam, respectively. In test category G, ceramic particles 11 are inserted only between scales 3 and 4, and sandy loam is inserted between scales 0-3 and 4-5.

The test results are shown in Fig. 4 (b). The numerical values in the figure indicate the degree of piercing, and the smaller the value, the higher the effect of preventing sig- rials. That is, in the test category A where the ceramic particles 11 in the sample X was 100%, an extremely high anti-white spotting effect was obtained. Also, in test categories B, C, and E, where ceramic particles 11 in sample X are 40% and 20%, the mixture with ceramic particles 11 is the collemanate. Regardless of whether it was sandy or sandy loam, a high siroi prevention effect was obtained. However, ceramic particles 1 In Fig. 1, the effect of colemanite mixed with sand loam was higher than that of sand loam. In addition, it can be said that the Shiroari prevention effect in test categories D and F using samples of colemanite alone or sandy loam alone is low or little. Furthermore, since the siroily prevention effect in the test section G is low, the sandy loam and the ceramic particles 11 are more effective than the ceramics particles 11 in a part of the sandy loam. It was found that a more uniform mixing (test section E) resulted in a higher anti-white spotting effect.

From the above, it has been found that the ceramic particles 11 can exhibit an excellent anti-whitening effect when mixed with other materials, particularly colemanate, at an appropriate ratio.

In view of the above test results, 2 parts by weight of the ceramic particles 11 and 8 parts by weight of the humidity control agent 1 mainly composed of a mixture of such ceramic particles 11 and colemanite were used. It is a mixture of this colemanite. This ratio corresponds to Test Category C, which has achieved extremely high repellent effects as described above. In particular, since the ceramic particles 11 and the colemanite powder are solid, they can be easily stored and transported, and are excellent in handling.

Next, a method of using the present embodiment will be described.

As shown in Fig. 5, before the foundation concrete section B of the building is cast at the building site, first, the soil in a place that can be the underlay of the foundation concrete section B S is stripped off and the top surface of the soil S, which is the base of the base concrete section B When a predetermined amount of Kuriishi a is spread over the stone to form the Kuriishi layer A, the humidifier 1 is poured to almost the height of the upper surface of the Kuriishi layer A, and pressure is applied from above to form the humidifier 1 layer. . After that, the base concrete section B is placed on the layer of the humidity control agent 1 via the moisture-proof sheet WRS. With such an extremely simple operation, the humectant 1 can be mixed into the soil S at a predetermined location, and the following effects are exhibited.

That is, when the humidifier 1 is used by mixing it in the soil S or spraying it on the soil S, first, the hiba oil 12 is removed from the pores 11 a of the ceramic particles 11. It volatilizes, and due to the action of hinokitiol contained in the Hiba oil 12, a whitening-proofing effect and the like is exerted in the soil S. Ali can prevent damage. In addition, the humidity control agent 1 exhibits an extremely good anti-whitening effect, in combination with such an effect of hinokitiol and the natural repellent effect of colemanite. You. In addition, the effect obtained by the released hinokitiol is not only an anti-sickling effect, but also an insect repellent effect against mites and other pests, and a disinfecting and antibacterial effect against mold bacteria and the like. Needless to say, the humidity control effect inherent to colemanite is exerted, and the ceramic particles 11 that have finished releasing hiba oil 12 have pores. Since the surrounding moisture is adsorbed to the part 11a or the adsorbed water is released, the humidity control action is exerted.

Mix humidifier 1 and cement powder in water at a predetermined ratio. Therefore, by pouring it thinly onto the stone bed A laid in the soil S and using it as the base for the base concrete section B, it is possible to use the same excellent escaping method as described above. The effects can be fully exhibited. In addition, the ratio between the ceramic particles 11 and the colleminate can be appropriately changed within a range that does not significantly impair the siroily prevention effect in consideration of cost effectiveness. In addition, it is a matter of course that the above-mentioned humidity control agent 1 may be used as a termite controlling agent, and at the same time, a humidity control effect may be obtained.

In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. Industrial applicability

Since the present invention has the above-described configuration, it is possible to provide a humidity control agent having a long-term high humidity control effect and a long-term control effect. In addition, such a humectant can be mixed into the soil underlying the base concrete part before casting the base concrete part of the building. It is possible to perform both under-floor humidity control and termite control at the same time.
