Description

  The present invention relates to a curable termite control composition and a kneaded product using the same.

  Conventionally, various measures have been studied in order to protect buildings from damage caused by termites.

  As an example of the above measures, Patent Document 1 describes a curable termite control composition in which a hydraulic component, an earth and sand component, and a termite control component are blended and kneaded, and this curable termite control composition is described as follows. For example, it is described that a termite intrusion is prevented by laying on a foundation portion of a building to form a dense termite control layer.

  Patent Document 2 describes a termite control method using a granular carrier containing a non-repellent insecticide.

International Publication No. 2005/032253 Pamphlet JP 2005-154364 A

  In the curable termite control composition described in Patent Document 1, as earth and sand components, a gravel component having a particle size of 2 mm or more, a fine particle component (crude sand having a particle size of about 0.2 to 2 mm, and a particle size of 0.02 to 2 mm). And a mixture of at least one selected from fine sand of about 0.2 mm).

  On the other hand, in the termite control method described in Patent Document 2, as the granular carrier, a granular carrier having a large particle diameter of 3 mm or more and 8 mm or less, or a granular carrier having the above large particle diameter, and a longest particle diameter of 1 mm or more and less than 3 mm A mixture with a granular carrier is used.

  However, as in Patent Document 1, when a gravel component having a particle size of 2 mm or more is blended as an earth and sand component, the termite control layer having a small thickness can be produced without causing variations in thickness or coating defects. It becomes difficult to form.

  In Patent Document 2, an attempt is made to control termites with a layer of a granular carrier formed by spreading the granular carrier. However, although the granular carrier having a large particle size as described above can physically prevent termite penetration when a layer is formed, for example, a gap between a double foundation (an existing building by extension and an extension building foundation) It is not possible to process the gap between the outer heat insulating material and the base bonding part, so that a sufficient ant protection layer cannot be formed, and it is sufficient because the particle size is large for the joints of concrete that termites are likely to enter However, there is a problem that an effective control effect cannot be obtained.

  Accordingly, an object of the present invention is to provide a curable termite control composition that has an excellent termite control effect and can form a uniform layer having a small thickness when cured, and a kneaded material using the same. There is.

  As a result of earnestly examining the curable termite control composition that can achieve the above-mentioned object, the present inventors have found that the above problem can be solved by using earth and sand having a specific particle size distribution as the earth and sand component.

  In addition, the termite control layer obtained can sufficiently exert the termite control effect due to the termite control component, and even when the termite control component is not included, the termite control layer has an appropriate hardness. Therefore, harm can be applied to the termites that have eaten them to penetrate the termite control layer. In addition, the hydraulic component in the curable termite control composition is often a strong alkali component. Therefore, when a termite eats the termite control layer, a large amount of strong alkali component is taken into the termite body. The environment (acidity) inside the termite body is destroyed, and termites can be killed. That is, as a result, it is possible to highly suppress the damage caused by termites and the invasion of termites.

  The curable termite control composition can be applied to the above-described treated area by various methods.

  Next, the termite control method of the present invention using the curable termite control composition of the present invention will be described.

  The first termite control method of the present invention includes a kneading step for kneading the first or second curable termite control composition and a curable liquid, and a kneaded product obtained in the kneading step for controlling damage caused by termites. And a curing step in which it is applied to the site to be cured and cured.

  In the kneading step, the first or second curable termite control composition and the curable liquid are blended and kneaded to obtain a kneaded product.

  The curable liquid is a liquid used when the first or second curable termite control composition is cured. Specifically, for example, water, a termite control solution containing a termite control component, a polymer And liquids containing

  The termite control component of the termite control solution containing the termite control component (hereinafter sometimes simply referred to as “termite control solution”) includes any component of the first curable termite control composition or the second component. The same termite control component as exemplified as an essential component of the termite control composition is included.

  Examples of the solvent or dispersion medium for the termite control solution include water, methanol, ethanol, propylene glycol, and the like.

  As the polymer in the liquid containing the polymer, the kneaded product with the first or second curable polymer, or the liquid containing the polymer itself is applied to the site to control the damage caused by termites (coating, Polymers that can be cured with the first or second curable polymer when sprayed, sprayed, injected, etc.

  Specific examples include ethylene-vinyl alcohol (EVA) resin, acrylic resin (for example, acrylic ester, methacrylic ester, etc.), styrene-butadiene rubber (SBR), and the like.

  Examples of the liquid solvent or dispersion liquid containing the polymer include water. The liquid containing the polymer is specifically supplied as a dispersion, suspension or emulsion containing the polymer, more specifically, for example, as a resin emulsion or rubber latex. .

  The blending ratio of the first or second curable termite control composition and the curing liquid may be within a range in which the kneaded product can be cured to form a termite control mortar. Therefore, although not particularly limited, for example, the amount of the water, solvent or dispersion contained in the curable liquid is preferably based on 100 parts by weight of the first or second curable termite control composition, It is 15 to 65 parts by weight, more preferably 15 to 45 parts by weight, and still more preferably 15 to 35 parts by weight.

  For the kneading of the first or second curable termite control composition and the curable liquid, for example, a mixer or the like may be used, or the mixture may be stirred by hand. Examples of the kneading method include a method in which a curable liquid is put in a container in advance and the curable termite control composition is gradually added while stirring the solution.

  In the said hardening process, the kneaded material obtained by the said kneading | mixing process is applied to the site | part which controls the damage by a termite, for example, Then, it leaves still in the state which refused the contact with the surface of the applied kneaded material. Thereafter, the kneaded product is cured by being left still or by absorbing moisture in air or soil. Thereby, termite control mortar is formed.

  Specific examples of the application of the kneaded product include coating, spreading, spraying, pouring, embedding, and the like of the kneaded product.

  The specific method of the construction is not particularly limited, for example, a method of coating the kneaded material with a tool such as a spatula or a spatula, the kneaded material with a machine / equipment such as a sprayer, a sprayer, or a pump.

  In addition, when using a spreader, the above-mentioned kneaded material and the like can be sprayed from the tip of the hose by a certain amount, so that, for example, the work efficiency of the termite control composition is particularly low when constructing a termite control composition under an existing house floor. Can be increased. In addition, when a spray gun is used, spray coating of the kneaded material or the like is possible, and furthermore, construction with a uniform thickness is possible. Furthermore, for example, work efficiency can be improved even in construction in a very narrow construction area such as a double foundation.

  The curable termite control composition used in the kneading step of the first termite control method may be one that does not contain a termite control component (first curable termite control composition) and contains a termite control component. (Second curable termite control composition) may be used.

The termite control component is contained in the control mortar), and the termite control effect can be surely exhibited. On the other hand, when the termite-controlling composition does not contain a termite-controlling component and the curable liquid is a liquid containing water or a polymer, termites are added to the cured product (termite-controlling mortar). Although the control component is not contained, the termite that harms the cured product as described above can exert the termite control effect by incorporating a large amount of the cured product in the affected area. In order to exert such an effect, it is preferable to set the compression strength of the cured product (termite-controlling mortar) obtained by curing the kneaded product to be in the above range.

  In the first termite control method, the construction area in the case where the kneaded product obtained in the kneading step is applied, sprayed or sprayed is a site for controlling damage (including extermination) due to termites.

  Even if the termite-controlling composition does not contain a termite-controlling component, the termite-controlling composition is cured when the curing solution sprayed or injected in the spraying / injecting step is a termite-controlling solution. The termite control component is contained in the cured product (termite control mortar) obtained in this manner, so that the termite control effect can be surely exhibited. On the other hand, when the termite-controlling composition does not contain a termite-controlling component, and the curable liquid sprayed or injected in the spraying / injecting step is a liquid containing water or a polymer. The termite-controlling component is not contained in the cured product (termite-controlling mortar) obtained by curing the termite-controlling composition. However, as described above, the termites that damage the cured products are the above-mentioned curing in the affected area. By taking in a large amount of substances, the termite control effect can be exhibited.

  For forming and solidifying the kneaded product, for example, a method of pouring the kneaded product into a plastic container or a wooden frame to solidify and taking out is used. At that time, for example, the kneaded product can be molded and solidified according to the shape of the portion actually damaged by termites or the shape of the portion drilled with a drill or the like.

  In the embedding step, for example, the molded body obtained in the molding and solidifying step may be subjected to damage caused by termites, in particular, sites that are actually damaged by termites (damaged parts) or may be damaged by termites.

  In Reference Examples 16 and 17, although the test sample layer 5 was not penetrated, several mm perforations were observed. However, in both Reference Examples 16 and 17, all termites died one week after the release.

  In contrast, in Comparative Example 1, about 15% of termites were healthy after one day, and in Comparative Example 2, all of the termites were healthy.

In the above control, when the mixture A was used, several mm perforation was observed in the test sample layer 5, and the effect of termite control was slow, and even after 3 weeks, about 80 %Met. When the mixture B was used, penetration was observed in the test sample layer 5 on the day after the start of the test, and even after 3 weeks, the termites were all healthy within the range in which the appearance could be observed. When the mixture C was used, no perforation was observed in the sample layer 5 (compressive strength: about 28 N / mm ² ), and even after 3 weeks, the termites were healthy in the range where they could be observed by appearance. there were.

In addition, in the other control, no perforation of the cube (compressive strength of about> 30 N / mm ² ) was observed, and even after 3 weeks, the termites were healthy in the range where they could be observed by appearance. .

  From these test results, by setting the hardness of the test sample layer and the particle size of the earth and sand component in the curable termite control composition forming the test sample layer to a range suitable for termites to harm, It was found that a certain termite control effect was obtained.

  In addition, it penetrated similarly to the case where the termite control composition of Reference Example 1 was used except that the test sample layer 5 was formed using only untreated silica sand instead of the curable termite control composition. When the test was performed, it was observed that the termites 7 reached the pine feed tree (untreated test piece) 6 one day after the release.

(2) Scooping-up test The scooping-up test is a test that can confirm the effectiveness on the surface on which the termite control agent has been applied. it can.

  FIG. 5 is a front view showing the test apparatus used in the scooping test.

  In the test apparatus shown in FIG. 5, an untreated hydrous sand (water content: 10% by weight) is spread on a polycup (inner capacity: 500 mL) 10 having a bottom diameter of about 8 cm, and a hydrous siliceous layer 11 having a thickness of 3 cm. A concrete block 12 having a rectangular parallelepiped (bottom surface 30 mm square, height 60 mm) was placed in the center of the obtained hydrous siliceous layer 11. On the side surface of the concrete block 12, in the region of width 50 mm from the edge on the top surface side to the bottom surface side, the above Reference Examples 1 to 12, Example 13, Reference Examples 18 to 23 and Comparative Examples 1, 2, and 4 The obtained curable termite control composition was applied to form mortar 13.

  The curable termite control composition was applied to the side surface of the concrete block 12 after blending 20 parts by weight of water with 100 parts by weight of the curable termite control composition and after 2 hours with occasional stirring. Moreover, after application | coating, after storing the concrete block 12 at 40 degreeC for 2 weeks, it used for the scooping up test.

The coating amount of the curable termite control composition was adjusted to be 300 g / m ² . Moreover, in the side surface of the concrete block 12, about 10 mm in width | variety from the edge of the bottom face side to the top | upper surface side, in order to prevent a termite prevention component etc. eluting to the hydrated siliceous sand layer 11, it did not process. .

  After the concrete block 12 was installed at the center of the hydrous siliceous layer 11, two pine feeding trees 14 having a tip of 1 cm × 1 cm and a length of 2 cm were arranged on the concrete block 12.

  Next, 100 ants of termites were released on the hydrous siliceous layer 11 and the opening of the polycup 10 was sealed with a wrap. After the release, the behavior of the termite 7 was observed all day and night. Moreover, the behavior of the termite 7 after 3 weeks from the release was observed.

  In this test, for several hours after the start of the test, it was observed that the termite 7 was surprised by the environmental change and climbed up the side of the concrete block 12 to reach the bait 14. However, when one day passed, the behavior of the termite 7 was settled, and as a result, the influence by the curable termite control composition (mortar 13) became observable.

  The results of the scooping test are shown in Table 1.

  In Table 1, “moving” indicates that termites go back and forth (up and down) between the hydrous siliceous layer 11 and the bait tree 14 through the surface of the concrete block 12. “Non-treatment” indicates a case where the curable termite control composition was not applied to the side surface of the concrete block 12 (the mortar 13 was not formed).

(3) Construction test Termite habitats (eg, the first and second floors of a building, places where there is a risk of termite damage such as underground, and termite nests and ant roads other than buildings). A construction test was conducted as a target.

  The construction site is not particularly limited as long as it is a place where termites are generated or a place where there is a possibility of occurrence, but as a place where it is likely to occur, for example, a foundation structure part of a building (for example, a heat insulating material, a concrete crack, etc. Gaps, for example, heat insulating materials in walls, for example, xylem that forms the foundation part of the foundation, for example, xylem that forms the underfloor, such as oiki, jota, floor bundles, rooting, such as door frames, pillars , Xylem that constitutes living space such as closet, for example, timber that constitutes ceiling such as trunk difference, two-storied floor, for example, xylem that constitutes the back of a hut such as a shed, haze, etc. Eaves, window frames, entrances, kitchens, etc., which are partly or entirely exposed to the outside, etc.), for example, underground structures of buildings (for example, timbers, cracks in concrete) For example, underground as ancillary equipment for buildings設物 (e.g., wire and cable, such as a gas pipe underground installations) include, for example, garden stump.

Construction test 1
90 parts by weight of the above-mentioned dry earth and sand A and 10 parts by weight of Blast Furnace Cement Type B (manufactured by Taiheiyo Cement Co., Ltd.) are mixed, and 100 parts by weight of the resulting mixture is used for termite control agents (Takelock MC50E, Nippon Enviro Chemicals Co., Ltd.). 2) parts by weight were blended. Next, the obtained curable termite control composition and 18 parts by weight of water were blended and kneaded.

  Next, a penetration test was performed in the same manner as in the above (1) except that the kneaded material thus obtained was used as a test sample.

  Further, a scooping test was performed in the same manner as in the above (2) except that the kneaded material was applied to the side surface of the concrete block 12 to form the mortar 13.

  As a result, in both the penetration test and the scooping test, after one day from the termite release, all of the heads had fallen and then died. Further, in the penetration test, no perforation of the kneaded material layer by termites was observed.

Construction test 2
90 parts by weight of the dry earth and sand A and 10 parts by weight of blast furnace cement B type (manufactured by Taiheiyo Cement Co., Ltd.) were mixed, and the resulting curable termite control composition was subjected to the penetration test of (1) above.

  Then, 20 parts by weight of a termite control agent (Takelock MC50E) diluted 50 times with water is applied to 100 parts by weight of the sample layer 5 from above the sample layer 5 in the cylinder 3. Furthermore, the behavior of termites was observed. The test sample layer 5 was solidified.

  As a result, one day after the termite was introduced, all the termites fell and then died. Moreover, no perforation of the test sample layer 5 by termites was observed.

  According to the construction tests 1 and 2, it was confirmed that a sufficient effect of termite control can be obtained even when a termite control component is blended in the mortar construction site.

Construction test 3
As shown in FIG. 6 (a) and FIG. 6 (b), of one surface (10cm square) of a concrete block (cuboid with a thickness of 3cm, a width of 10cm, and a height of 10cm) 30, the height from the bottom surface side is about An adhesive (Super X, manufactured by Cemedine Co., Ltd.) 31 was applied at a distance of 5 cm from each end of the concrete block 30 with a length of 2 cm and a width of 1 cm. Then, the concrete block 30 and a heat insulating material 32 (Kanelite Foam FI, manufactured by Kaneka Corporation) having the same size as the concrete block 30 were bonded with the adhesive 31 interposed therebetween. At this time, a gap 33 of 0.5 mm was generated between the heat insulating material 32 and the concrete block 30. The adhesive consisting of the concrete block 30 and the heat insulating material 32 is a 2 mm acrylic plate so that there is no gap on the surface (excluding the surface of the heat insulating material 32 that faces the bonding surface with the concrete block 30). 34 was adhered.

  In addition, on the surface side of the heat insulating material 32 facing the bonding surface with the concrete block 30, the side surface is so that the upper part protrudes 1 cm from the bottom part, and the bottom part protrudes 3 cm to the heat insulating material side. The acrylic plate 34 was bonded so that the bottom on the heat insulating material side protruded at a height of 3 cm and a width of 3 cm, and further the upper portion protruded by 1 cm. The acrylic plate 34 was bonded to the portion that protruded from the front surface of the portion that protruded from the bottom and side surfaces of the lower portion. An untreated hydrated siliceous sand (water content 10 wt%) 35 was spread over the part that protruded over the entire surface.

  Next, 5 g of the curable termite control composition obtained in Reference Example 4 was sprayed from the upper part of the gap 33 between the heat insulating material 32 and the concrete block 30, and water was sprayed to such an extent that it was moistened from above. The curable termite control composition was then solidified.

  Furthermore, when 300 state ants are released on the untreated hydrous silicic sand 35 and the state is observed, the termites damage the heat insulating material 32 through a gap of 2 mm below the heat insulating material 32.

  Further, in place of the curable termite control composition obtained in Reference Example 4, 5 g each of the curable termite control composition obtained in Comparative Example 1 and the termite control granule obtained in Comparative Example 3 were used. In the same manner as above, the state of the termites was observed.

  As a result, when the curable termite control composition of Reference Example 4 was used, the termites fell 100% after 1 day, and the death of all the termites was observed after 2 days.

  On the other hand, when the curable termite control composition of Comparative Example 1 was used, the termites fell about 20% after 1 day, and about 70% fell after 3 days. During this time, damage to the heat insulating material 32 was observed. One week later, all animals died.

  In addition, when the termite control granule of Comparative Example 3 was used, the fall of the termites was not observed after one day, the damage of the heat insulating material 32 progressed, and the termites that reached the top of the heat insulating material 32 were observed. It was. One week later, the fall of termites was observed, and after 10 days, all deaths were observed.

  From the above results, it was observed that in the case of the gaps as described above, higher efficacy was obtained with the powdery preparation. Moreover, it was suggested that the longer the time until the tipping over, the more the damage to the heat insulating material proceeds and the function as the heat insulating material may be impaired.

Construction test 4
The double foundation by renovation tends to cause gaps and tends to be an entry route for termites. In addition, gaps such as cracks that occur in underfloor concrete, including gaps in double foundations, are not attacked by external enemies and require less labor for building ant roads.

  As shown in FIG. 7, two concrete blocks (a rectangular parallelepiped having a thickness of 3 cm, a width of 10 cm, and a height of 10 cm) 40 were provided with a gap 41 having a width of 1 mm. Next, 5 g of each curable termite control composition obtained in Reference Example 4 was sprayed from above the gap 41.

  Also, the curable termite control composition obtained in Comparative Example 1, the termite control granule obtained in Comparative Example 3, the carrier A described in Reference Example 4, and 5 g of water, respectively, Similarly, it sprayed in the clearance gap 41 between a pair of concrete blocks 40. FIG.

  After spraying, the pair of concrete blocks 40 were turned over, one concrete block 40 was removed, and the sprayed state was observed.

  As a result, as shown in FIG. 8A, it was observed in Reference Example 4 that the curable termite control composition 42 was uniformly treated in the gap 41.

  On the other hand, in Comparative Example 1, as shown in FIG. 8B, the large particles 43 became an obstacle, and the amount of the termite control composition 42 in the gap 41 was small.

  Moreover, in the comparative example 3, as shown in FIG.8 (c), the termite control composition was not observed in the clearance gap 41. FIG. The carrier A was treated uniformly as in Reference Example 4 (see FIG. 8A). Since the amount of water 44 absorbed by the upper part of the concrete block 40 is large, the water 44 is only allowed to sag and cannot be uniformly treated (see FIG. 8D).

Construction test 5
The test sample (a pair of concrete blocks 40) in which the reference example 4 and the carrier A were processed in the gap in the construction test 4 was placed on the tray as it was, and the condition was 1 under the conditions of humidity 100% RH and temperature 28 ° C. Stored for months. One month later, when the sample was lifted from the tray, as shown in FIG. 9, it was observed that a large amount of the processed material 45 spilled from the adhesion surface of the specimen (concrete block 40) treated with the carrier A. On the other hand, in Reference Example 4, no spilling state was observed, and a state in which a uniform treatment layer was formed while remaining solidified in the gap was observed. This means that even if the space is opened by other organisms such as moles under the treatment construction surface, the soil is washed away by infiltration of groundwater or rainwater, the space is opened, or the gap is opened by an earthquake, etc. Although the treatment layer is not lost, it shows that the preparation layer that does not solidify may collapse and dissipate.

  From the construction tests 3, 4 and 5, it was confirmed that in a narrow space such as a gap, a preparation having a fine particle size and solidifying can be expected to have a clearly higher effect than a preparation having a large particle size or a preparation that does not solidify. .

Construction test 6
An untreated hydrated siliceous sand (water content: 10% by weight) is spread on a polycup (with an internal volume of 500 mL) having a bottom diameter of about 8 cm to form a 3 cm thick hydrated siliceous sand layer.
