Description

  The present invention relates to an anti-evaporation agent composition for sealing water in a water-sealed drain trap attached to a drain outlet, piping, and the like, and a method for preventing evaporation of sealed water using the composition. The present invention relates to an evaporation inhibitor composition that is used by being mixed with water and can prevent evaporation of the sealed water, and an evaporation prevention method.

  2. Description of the Related Art Conventionally, various drainage devices that generate drainage by using a bathtub, bathroom, washstand, sink, and the like have been attached with a drainage device that discharges the drainage generated by use to the sewage side such as an underfloor pipe. These drainage devices are generally provided with a water-sealed drain trap having a function of preventing odors from the sewage side, pests and small animals from entering the indoor side. This water-sealed drain trap is provided with a portion of water drainage in the drainage channel where water is collected, and prevents odors, pests and small animals from the sewage side from entering the room. Examples of such water-sealed drain traps include those described below. For example, in the wash basin 10 of FIG. 5 (a), the pipe immediately below the suction port for drainage of the sink 14 that receives water from the outlet of the water tap 12 is formed into an S-shape, and a water seal is provided to provide the sealed water 18 A stored S-trap water-sealed drain trap is used. The pipe 20 that has passed this S-trap type water-sealed drain trap extends vertically downward. FIG. 5B shows a drainage system 40 using a P-trap water-sealed drain trap. In the pipe 44 bent in such a manner that the P-shaped side is tilted sideways, the receiving portion 42 that receives drainage such as a funnel is similarly provided with a water-sealing portion at a downwardly convex bent portion, and the sealing water 46 Is accumulated. Thereby, the odor etc. which come from the tip 48 of a drain pipe can be interrupted | blocked. FIG. 5C shows a drainage system 60 that uses a U-trap type water-sealed drain trap in which pipes are bent in a U-shape to store sealed water. Here, similarly, the U-shaped pipe forms a water sealing portion, and the left side 62 and the right side 66 of the pipe are blocked by the stored sealing water 64.

  Moreover, as shown in FIG.5 (d), it can be said that the flush toilet 80 is also a kind of water-sealed drain trap. Sealed water 84 is stored in the concave portion of the toilet 82, and the partition plate 86 blocks odors and the like from the drain pipe 86 ahead. Further, FIG. 5 (e) shows a water-sealed drain trap 100 used in a kitchen sink, a drain outlet such as a bathroom floor. Such a drain outlet is provided with a rising portion by allowing the water distribution pipe 110 to enter the substantially central position of the bottom of the bottomed cylindrical main body 106 opened upward. From above the rising portion, a cap member 104 having a hook-like shape or a hook-shaped (bell) shape that is open downward is covered. The rising portion and the bottomed cylindrical main body 106 form a storage portion that can store the sealing water 108, and the side wall of the cap body 104 forms a sealing portion that blocks odors and the like. A disc-shaped eye plate 102 having a large number of openings is disposed on the cap body 104 in order to remove solid matter mixed in the drainage. Such a water-sealed drain trap 100 is usually referred to as a belt wrap or one trap because the shape of the cap body 104 is bell-shaped (hanging-shaped) or hook-shaped.

  As described above, in the water-sealed drain trap, water used as sealed water plays an important role in order to block odors and the like. In these water-sealed drain traps, a part of each drainage is stored in the water-sealed part and sealed, so there is no problem when draining frequently. When the amount of water is reduced, there is a possibility that the function of blocking odors or the like may not be provided due to natural evaporation of water as sealed water. In particular, the belt-wrap type or one-trap type water-sealed drain trap shown in FIG. 5 (e) has a large amount of water to be sealed and a large area of the opening. There is a risk that it will not be able to serve as a trap in a short period of time. In particular, if you are away from home for long periods of time, if the long-term contract for rental housing is not vacant, or if you are not in a villa that is not used for a long period of time, the function deterioration due to water evaporation will frequently occur. In some cases, the room was filled with unpleasant sewage odors, and a large number of pests and small animals entered the room. Further, in a drain trap installed indoors in a high-temperature atmosphere such as a boiler room or a power generation room, the above-mentioned phenomenon occurs in a relatively short period because the evaporation rate of the sealed water is increased.

Therefore, it is necessary to regularly monitor the sealed water in the water-sealed drain trap and replenish the reduced sealed water as appropriate, but periodically visit the vacant space of the rental housing or do not bother to use it. In order to check and replenish the sealing water of all the drain traps, it takes a lot of labor and is not economically preferable. Therefore, for example, in Patent Document 1, there is a drain trap that has a configuration in which the drain suction port can be hermetically sealed so that the intrusion of bad odor can be blocked even if the sealed water in the water seal portion of the water sealed drain trap evaporates and disappears. It is disclosed. Further, Patent Document 2 discloses an automatic water replenisher for automatically replenishing a decrease caused by evaporation of the sealed water in a water-sealed drain trap and maintaining the sealed water for a long period of time.
JP 2000-328625 A JP 2004-332472 A

  However, the drain trap disclosed in Patent Document 1 prevents odor due to a decrease in seal water, and does not restore the function of the water seal drain trap itself. In this technique, not only the function of preventing odor is not sufficient, but also the function as a normal drain is hindered. That is, it is necessary to open and close the drain suction port every time drainage is performed. Therefore, if the water is accidentally drained without opening the drain suction port, the drainage is not performed, and there is a possibility that the water overflows in the vicinity of the drain port.

  In addition, the automatic water sealer disclosed in Patent Document 2 is a device for automatically replenishing the decrease due to evaporation of the sealing water in the drain trap and maintaining the sealed water for a long time. Since there is no stoppage, the water in the automatic water-sealing water replenisher will eventually disappear and the function of the water-sealed drain trap will be lost. If it is to be maintained for a longer period of time, the automatic water sealer must be large, and is not a sufficient solution in terms of ease of installation and cost. In particular, a house usually has at least 3 to 4 drainage traps such as a bathroom, a bathtub, a wash basin, a sink, etc. The labor of will also become enormous.

  In view of the above problems, the present invention provides an evaporation inhibitor composition that can effectively prevent evaporation of the sealing water in the sealing portion of the water-sealed drain trap. Moreover, the method which can prevent effectively the evaporation of the sealing water of a sealing part using this composition is provided.

  The sealing water evaporation inhibitor composition of the water-sealed drain trap of the present invention is used by mixing with water used as sealing water, and can effectively prevent water evaporation in the water-sealed drain trap. Moreover, by evaporating the sealed water evaporation inhibitor composition from water and flowing it from the drain port, it is possible to effectively prevent evaporation of water as the sealed water of the water-sealed drain trap.

This sealed water evaporation inhibitor composition has as its main component an oil-based component having a specific gravity smaller than that of water and a vapor pressure smaller than that of water. Furthermore, the sealed water evaporation inhibitor composition may contain a surfactant. Moreover, the method for preventing evaporation of the sealing water is characterized in that a predetermined amount of the sealing water evaporation inhibitor composition is mixed with water at a predetermined ratio, and after stirring, is allowed to flow to a drain outlet.

Specifically, the following can be provided.
(1) A sealant evaporation inhibitor composition for a drain trap, comprising an oil component having a specific gravity of less than 1.0 and a vapor pressure lower than that of water, and an aqueous component.

(2) The sealant evaporation inhibitor composition according to (1), further comprising a surfactant.

(3) Sealed water as described in (1) or (2) above, wherein the oil component contains at least one or more of fats, liquid paraffin, alcohol, ketone, aldehyde, ester, silicone and hydrocarbon An evaporation inhibitor composition.

(4) A method for preventing evaporation of sealed water in a drain trap, in which an oil-based component having a specific gravity of less than 1.0 and a vapor pressure lower than that of water and an aqueous component are mixed, stirred, and introduced into a drain trap.

(5) The sealing water evaporation prevention method according to the above (4), further mixed with a surfactant, stirred, and put into a drain trap.

Here, in the said sealing water evaporation inhibitor composition, it is preferable to contain 1-99 mass% of said oil-based components . Moreover, about the said aqueous component, it is preferable to contain 1-99 mass%. Therefore, the sealed water evaporation inhibitor composition may contain 1 to 99% by mass of the oil component and the balance may be the water component.

Moreover, in the said sealing water evaporation inhibitor composition, it is preferable to contain 0.001-30 mass% of said surfactant further. And in the said sealing water evaporation inhibitor composition, the said oil-based component and the said water-system component are 70-99 mass% in total, and it is good also considering the remainder as the said surfactant.

Moreover, the said sealing water evaporation inhibitor composition may contain the component which does not belong to any of the said oil-type component , the said water-system component, or the said surfactant. For example, it may contain a liquid that performs a predetermined function such as a dye or a preservative, or a solid component that is dissolved or sufficiently dispersed in the sealed water evaporation inhibitor composition.

The oil component may contain at least one or more of oils and fats, liquid paraffins, alcohols, ketones, aldehydes, esters, silicones, and hydrocarbons. In particular, oils and fats, liquid paraffins, and silicones are preferable. Here, liquid paraffin is a colorless liquid and non-volatile at room temperature, but has a slight odor. Insoluble in water. It is a Class 3 organic solvent and is flammable. It is a chemically stable substance and does not undergo oxidation under normal conditions. It is easy to emulsify and has excellent spread and permeability. Purity can be measured by the absorbance of ultraviolet light. Liquid paraffin is, for example, nujol, mineral spirit, mineral turpentine, white spirit, white oil, white mineral oil, petroleum spirit, mineral thinner, petrolium spirit, water paraffin, mineral oil, mineral oil white, medical paraffin ( medical paraffin), paraffin fax, saxol, USP mineral oil, adepine oil, Albolene, glymol, and the like.

  Silicone is a high molecular organic compound (polymer) having a siloxane bond as a skeleton. Those having a relatively low molecular weight are also called polysiloxanes. Structurally, it is a molecule in which the carbon of the main chain of the ketone is replaced by silicon, and is originally a silica ketone, but is abbreviated as silicone.

In the method for preventing sealing water evaporation of the drain trap, a non-volatile layer can be formed between the interface between the seal water already stored in the drain trap and air (phase). However, in the drain trap, the interface between the sealed water on the drain outlet side and the air (phase) can be easily accessed, but the interface between the sealed water on the sewage side and the air (phase) cannot be easily accessed. On the drain outlet side, an oil component or the like having a specific gravity smaller than that of water forming a nonvolatile layer may be introduced from the drain outlet. However, if there is no means for direct access to the sewage side, and if it can be done deliberately, a bendable pipe or tube can be inserted into the sewage side and oil-based components applied to the pipe or tube can be introduced. Even in this case, it is necessary to prevent the sealing water from flowing into the pipe or tube. It is because the oil-based component which the sealed water which flowed in prevents from moving to the sewage side. In the sealed water evaporation prevention method of the present invention, by mixing and dispersing the oil-based component having such a low specific gravity with the water-based component, the apparent specific gravity of the dispersed mixture is close to the specific gravity of water, and is introduced from the drain outlet. Due to the momentum applied, such dispersed mixture can be moved to the vicinity of the bottom of the sealing trap or beyond it to the sewage side. Thereafter, the oil-based components are separated by buoyancy and rise to the surface of the sealed water, but have already moved to the bottom or the sewage side, so at least a part of the sewage side sealed water and air (phase) It reaches the interface and can prevent direct contact between the sealed water and air (phase). For example, an oil component (1-99% by mass) having a specific gravity of less than 1.0 and a vapor pressure lower than that of water and an aqueous component (1-99% by mass) are mixed, dispersed, and put into a drain trap. . In order to make the dispersion easier, it is more preferable to further add a surfactant (0.001 to 30% by mass) and disperse by stirring or the like.

Here, the boiling point of the oil component is preferably equal to or higher than the boiling point of water. The oil component may be any component that does not substantially dissolve in water. For example, even if it dissolves to some extent , the insoluble part remains undissolved, and it is sufficient that the insoluble part can be phase-separated after mixing and emulsification. The solubility in water is more preferably 1% or less at room temperature. A low vapor pressure can mean that it is difficult to evaporate. For example, it is preferable that the vapor pressure is 20 mmHg or less at room temperature. More preferably, it is 10 mmHg or less. And it is still more preferable if it is 1 mmHg or less. This oil component is a liquid. Further, the specific gravity is preferably smaller than water, for example, 0.999 or less. More preferably, it is 0.95 or less. From the viewpoint of quick phase separation, 0.9 or less is even more preferable. However, when the specific gravity is too small and the fluid has high water repellency, phase separation may occur rapidly, and dispersion may not be sufficiently performed. Such oil-based components may be physically and / or chemically generated by mixing two or more compounds. Moreover, the thing with a comparatively low viscosity which can spread the layer on the surface of water is preferable. Further, it is preferable that the covering property is high so that water is difficult to diffuse and come out on the surface.

  The sealing water evaporation inhibitor composition of the water-sealed drain trap according to the present invention does not require any special equipment, prevents evaporation of the sealing water for a long time, and maintains the function of the original water-sealed drain trap for a long time. Is possible.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the embodiments are described for understanding the present invention and do not limit the scope of the present invention.

  FIGS. 1 (a) to (e) illustrate a drainage system to which the sealed water evaporation inhibitor composition of the present invention is applied. Since the basic configuration of the drainage system is the same as that shown in FIGS. 5A to 5E described above, redundant description is omitted here. In FIG. 1 (a), the sealed water 18 is stored in the sealed water portion, but the component 22 composed of the sealed water evaporation inhibitor composition of the present invention is formed on the portion corresponding to the free surface in contact with the atmosphere. It spreads in layers. This component is a liquid and has a specific gravity smaller than that of the water 18 and forms a layer on the surface of the water 18. This component is harder to evaporate than water, and even if it is exposed to the atmosphere for a long time, the layer does not easily become thin due to evaporation. For example, the vapor pressure is lower at room temperature than water, or the boiling point is higher than water. In addition, the diffusion of water in the layer is a low component so that the water underneath is difficult to diffuse in the layer and evaporate on the surface. Thus, since the path | route in which the sealing water 18 evaporates is covered with this component, the evaporation of the sealing water 18 can be suppressed to an extremely low level.

  In FIGS. 1 (b), (c), (d), and (e), similar components 50, 68, 88, and 112 also cover the surfaces of the sealed water 46, 64, 84, and 108, respectively. It is effectively preventing. Therefore, evaporation of the sealing waters 46, 64, 84, and 108 can be suppressed to an extremely low level. Therefore, it is possible to maintain the function of the water-sealed drain trap for a long time.

  FIG. 2 illustrates a method of applying the sealed water evaporation inhibitor composition of the present invention, taking the wash basin 10 as an example. A predetermined amount of the seal water evaporation inhibitor composition 202 is contained in a container 200 made of a material inert to the water and seal water evaporation inhibitor composition. There, water 206 is mixed from a pipe 204 such as a water supply at a predetermined ratio. When the container 200 is sealed and allowed to stand for a while, a water phase 206, a sealed water evaporation inhibitor composition phase 202, and an air phase 208 are formed from below. When this is stirred up and down together with the container, the water phase 206 and the phase 202 of the sealing water evaporation inhibitor composition are mixed together from below, and an emulsified liquid 210 is formed. When the lid of the container 200 is opened and poured into the sink 14 of the wash basin 10, this mixture flows into the sealed water portion where the sealed water 18 has already been stored. When a large amount of the emulsified liquid 210 is charged, the emulsified liquid 210 is exchanged and collected in the sealed portion as shown in the lower left (b) of FIG. After a while, the sealing water evaporation inhibitor composition having a lower specific gravity spreads on the surface, covers the surface of the sealing water, and prevents evaporation (FIG. 1 (a)).

  On the other hand, when the amount of the emulsified liquid 210 to be added is small, as shown in the lower right (c) of FIG. 2, the emulsified liquid 210 enters the sealed water stored in the sealed water portion, and the bottom of the sealed water portion is removed. It reaches over to the sewage side. After a while, the already accumulated water and the newly added water merge to form an aqueous phase at the bottom, and the sealed water evaporation inhibitor composition having a lower specific gravity spreads on the surface. In this way, the seal evaporation inhibitor composition that has been dispersed and moved together with the water introduced into the sewage side also covers the surface of the sewage on the sewage side, and the seal water evaporates on both sides. Is prevented (FIG. 1A).

  It can be thought that evaporation can be prevented if the surface of the sealed water is covered by any method. However, covering the surface of the sealed water up to the opposite side bent into the S-shape in a narrow water distribution pipe Although this method was extremely difficult, this method can easily cover the surface of the sealed water, and the covering composition is a liquid and can easily flow without clogging the water pipe. it can. Moreover, in the sealing water evaporation inhibitor composition containing an oil-based component, BOD or COD may be deteriorated. As shown in FIG. 2 (c), the sealing water may be sealed with a small amount of the sealing water evaporation inhibitor composition. More preferably, evaporation is prevented.

Here, the components contained in the sealed water evaporation inhibitor composition of the present invention will be described in more detail. The main component of the sealed water evaporation inhibitor composition of the present invention is an oil-based component having a specific gravity smaller than that of water and a vapor pressure smaller than that of water . In addition to various oils and fats, liquid paraffin and other oil-based substances that are usually used for food , alcohols, ketones, aldehydes, esters, silicones (eg, cyclic polyalkylsiloxanes), various essential oils, And oil-based substances such as hydrocarbons. From the viewpoint of use, it is desirable that these have no odor, are weak, or do not have an unpleasant odor. These may be used alone or in a mixture of two or more. That is, in FIG. 2, at the stage of mixing with water, a water-insoluble material having a specific gravity smaller than that of water and a vapor pressure smaller than that of water may be generated. May be used. Such a main component is mix | blended in the ratio of 1-99 mass% in a sealing water evaporation inhibitor composition. If the blending amount is less than 1% by mass, there is a possibility that the intended ability to prevent evaporation is poor. Although it is possible to apply such a composition to a sealing part without water, since it is an oil-based liquid in many cases, the smaller one is preferable from the surface of environmental load.

  Further, as shown in FIG. 2, it is also possible to prepare a sealed water evaporation inhibitor composition that is not added with water later but can be mixed with an aqueous liquid in advance and allowed to flow as it is into a drain pipe. In such a case, the oil component as the main component is preferably 2 to 30% by mass from the viewpoint of environmental load. Examples of the water-based component to be mixed include pure water, soft water, distilled water, and normal tap water. These may be used alone or in combination of two or more. From the viewpoints of economy and storage stability, tap water and ion-exchanged water are preferable. This aqueous component may be blended in the ratio of 1 to 99% by mass in the sealed water evaporation inhibitor composition. More preferably, it is 10-70 mass%.

  The water-sealing type inhibitor composition of the present invention may further contain a surfactant. This surfactant is composed of an oil component as a main component and water added later (when water is added to a sealant evaporation inhibitor composition) or the above-mentioned water component (sealed sealant composition). In which the oil component of the contents can be emulsified and dispersed in water by simply shaking it up and down before use. That is, it is blended so that it can be mixed quickly and uniformly with simple stirring when it is put into the water seal portion. In addition, it is possible to provide an effect of cleaning dirt in the drain trap that is left for a long time. It is also possible to provide an effect of preventing dirt from adhering to the drain trap that is left for a long period of time. Furthermore, when returning the drain trap that has been left for a long period of time to normal use, it is possible to provide an effect that the oil-based component is quickly discharged from the drain trap by simply flowing water. As such a surfactant, any of an anionic surfactant, a cationic surfactant, a nonionic surfactant, and an amphoteric surfactant can be used. Such a surfactant may be used alone or in a mixture of two or more. The oil component that is the main component described above and water added later (when water is added to the seal water evaporation inhibitor composition) or the above water component (sea seal water evaporation inhibitor composition) can be applied as it is. In a case where the surfactant is added to the drain trap, the surfactant is preferably added in such an amount that it can be emulsified and dispersed almost uniformly. That is, the amount of the surfactant is not particularly limited as long as the oil-based component and the water-based component are emulsified and dispersed almost uniformly, and can be put into the drain, but generally 0.001% by mass or more Is preferable, and 30 mass% or less is preferable. More preferably, it is 5 mass% or less.

  Further, in the drain trap sealing water evaporation inhibitor composition of the present invention, in addition to the above-described components, if necessary, the pigment, fragrance, essential oil, pigment, pigment dispersant, antiseptic, as long as the object of the present invention is not impaired. Agent, fungicide, disinfectant, sequestering agent, thickener, oil / water separation accelerator, insecticide, insect repellent, insecticide, bleach, alkali, acid, inorganic salt, organic salt, Solvents, plant extracts, deodorants, deodorants, enzymes such as proteolytic and oil-degrading enzymes, oxidizing agents, reducing agents, abrasives, polymeric water-absorbing agents, bacteria and yeast activators, etc. More than one species can be blended freely.

  The sealed water evaporation inhibitor composition of the present invention may be filled in a polyethylene bottle or the like and used as an evaporation inhibitor for sealed water. When used to prevent evaporation of the sealed water, it is shaken up and down before use to make the oil-based component and aqueous component emulsified or dispersed and put into the sealed water of the water-sealed drain trap. The charged sealing water evaporation inhibitor composition is mixed with the sealing water in a moderate amount, and evenly spreads to the sealing water. As time passes, the oil component separates into the upper part, and the oil component covers the surface of the sealed water. As a result, the effect of preventing evaporation of the sealed water for a long period of time can be obtained, and the function of the water-sealed drain trap can be maintained for a long period of time. Further, even when the actual use state is reached, the oil component is easily emulsified and dispersed by the power of the blended surfactant, so that the oil component is hardly fixed.

  The sealed water evaporation inhibitor composition of the present invention may be filled into a bottle and commercialized as described above, but may be filled into a bag of water-resistant polyethylene or the like, or may be filled into an aerosol. The product form can be freely selected, such as filling in a water-resistant paper pack.

(Experiment 1)
Hereinafter, specific experimental examples will be described. The materials shown in Table 1 were mixed according to the respective blending ratios, and 500 cc of each of Examples 1 to 3 and Comparative Example 1 were prepared and filled in a glass container. The product names, general names, and manufacturer names of each material are summarized in Table 2. The containers filled with these mixtures were sealed, shaken vigorously up and down 20 times respectively, allowed to stand, and the state of emulsification was visually observed after 10 seconds. The results are summarized in Table 1. Example 1 in which an oil agent, a surfactant, a preservative, a pigment, and water were mixed had a very good emulsified state. The emulsified state was also very good in Example 2 in which an oil agent, a surfactant, and water were mixed. In Example 3 to which only the oil and water were added, the emulsified state was slightly good, but separation started immediately after standing.

  Next, the above-mentioned composition after stirring was put into an S-shaped tube 300 shown in FIG. 3, and it was examined whether or not the oil component was moved to the sewage side. An S-shaped drain trap 300 was manufactured by processing a transparent vinyl chloride pipe and a joint. First, water was added, and the sealed water 18 was collected in the same manner as in normal use. Each of the compositions 210 of Examples 1 to 3 and Comparative Example 1 was shaken vigorously up and down 20 times, and 50 cc of each was poured from the drain outlet side, and it was visually observed whether the composition reached the water surface on the sewage side. As a result, as shown in Table 1, in Examples 1 and 2, it was found that the oil component sufficiently moved to the sewage side. In Example 3, it was recognized that the oil component slightly moved to the sewage side. Since Comparative Example 1 did not contain an oil-based component, it was excluded from the evaluation.

  Next, each of the compositions 210 of Examples 1 to 3 and Comparative Example 1 was shaken vigorously up and down 20 times in the transparent vinyl chloride S-shaped drainage trap in which the sealed water was stored, and 50 cc each was charged from the drain outlet side. Then, the water level on the sewage side immediately after was marked and stored at room temperature for 3 weeks, and then the decrease in the water level was measured. As a result, as shown in Table 1, in Examples 1 and 2, it was found that the water level was hardly lowered. In Example 3, although it was 11 mm lower, it was half of 22 mm of Comparative Example 1, and the effect of introducing the composition of Example 3 was recognized.

(Experiment 2)
FIG. 4 is a schematic diagram of a water-sealed drain trap used in the next experimental example. A prototype water-sealed drain trap 330 consisting of a transparent polyvinyl chloride water pipe with an inner diameter of 30 mm opens the drain port 332 vertically upward and extends approximately 250 mm vertically downward, where it bends approximately 90 degrees and is water-sealed drain. After forming the bottom of the trap 330 with a width of 130 mm, the trap 330 is vertically extended 140 mm upward, bent 90 degrees there, and horizontally extended to the sewage side 336. The sealed water portion 334 thus formed can store a sealed water amount of about 190 ml. Five such trial water-sealed drain traps 330 were prepared, and the sealed water 18 was stored in the sealed water portion 334, respectively. Moreover, the same composition as the said Example 1 was measured with the 10 ml, 20 ml, 30 ml, 40 ml, and 50 ml graduated cylinder, respectively, and was set as Examples 4, 5, 6, 7, and 8, respectively. In Experiment 2, the compositions of Examples 4 to 8 were thoroughly stirred in the container 200 to disperse the oil-based component and the water-based component, and from the drain ports 332 of the five prototype water-sealed drain traps 330, respectively. I put it in.

  As a result, in all of Examples 4 to 8, the dispersion composition 202 flowed into the sewage side 336 through the bottom of the water-sealed drain trap 330. After 1 hour, an oil film was formed at the interface between the sealed water and the air on the sewage side and the drain outlet side (that is, the surface of the sealed water). Therefore, 10 ml of the composition as in Example 4 can sufficiently form an oil film to prevent evaporation, but considering the influence of the charging method such as whether the operator is skilled or due to natural fall or injection, Example 5 Alternatively, an input of 20 to 30 ml of 6 is considered preferable. Furthermore, if the influence of dirt inside the piping is taken into account, and if a more complete oil film formation is desired, a larger amount of 50 ml is desirable. However, considering the environmental load, the smaller one is preferable.

  As described above, the optimum input amount varies depending on the composition, physical properties, etc. of the composition to be input, and also varies depending on the sealing amount, shape, dirt, etc. of the target water-sealed drain trap, and also prevents temperature and evaporation. It depends on the power period. However, it can be considered that the amount is approximately 5% or more, more preferably 10% or more, with respect to the amount of sealed water of 190 ml. Moreover, if there are few environmental loads, cost, etc., it is preferable that there are few. In the case of this experimental example, it is considered that an input amount of approximately 10 to 20% is preferable with respect to a sealed water amount of 190 ml.

  As described above, in the drainage trap sealing water evaporation inhibitor composition of the present invention, it was possible to prevent the sealing water from evaporating for a long period of time and maintain the function of the original water-sealed drain trap for a long period of time. In addition, even when a small amount of drainage trap seal evaporation inhibitor composition is added to the place where the oil-based components are more easily emulsified and dispersed by the action of the surfactant and the seal water has already accumulated, The oil-based component moves to the surface of the seal water and covers the surface, thereby preventing the seal water from evaporating. Moreover, not only the preservability of the composition itself is increased by mixing an antiseptic, but also an antiseptic effect on the sealed water after the addition can be expected.

It is a schematic diagram which shows a state when the composition of the Example of this invention is applied to a water-sealed drain trap. FIG. 2 illustrates a method for preventing evaporation of sealed water to which a composition of an example of the present invention is applied. It is a figure which illustrates Experimental example 1 of this invention. It is a figure illustrating Experimental example 2 of the present invention. It is a schematic diagram of the drainage system using the conventional water-sealed drain trap.
