Description

  The present invention relates to an organic material finishing material removal method for removing an existing organic material finishing material sprayed or adhered to, for example, a wall or a floor.

  Generally, as a wall or floor renovation work, for example, after removing the paint film sprayed on the wall or tiles stuck on the wall or floor to expose the ground surface, a new finishing material is applied to the ground surface. Construction to construct is carried out.

  In particular, in recent years, in view of the asbestos problem, renovation work has been carried out in which an existing organic material finishing material containing asbestos is removed and replaced with a finishing material not containing asbestos. For example, as a method of removing the existing coating film in the above-described renovation work, it is common to scrape the existing coating film using a wire brush, scraper, disc grinder or the like. On the other hand, as a method for removing the existing tile in the above-described renovation work, it is common to remove the existing tile while crushing the existing tile with a turning device such as a small breaker or chipper. Thus, when removing an existing coating film and an existing tile, since there exists a possibility that asbestos dust may fly, it is necessary to take the countermeasure which suppresses scattering of asbestos dust. In particular, it is necessary to take strict measures when performing renovation work while using the facilities.

  As a conventional countermeasure against scattering of asbestos dust, there is a means of scraping an existing coating film or crushing an existing tile while discharging water with a hose or the like. According to this means, scattering of asbestos dust is suppressed by water.

  Further, as a conventional countermeasure against scattering of asbestos dust, there is a means of using a negative pressure dust removing device with a HEPA filter (High Efficiency Particulate Air Filter). According to this means, the existing coating film can be scraped off or the existing tiles can be crushed while collecting the asbestos dust by the negative pressure dust remover, so that the asbestos dust can be prevented from being scattered.

  Conventionally, as shown in Patent Document 1 below, for example, there has been proposed a floor tile removing device that collects fragments of existing tiles while crushing existing tiles. According to this floor tile removing device, asbestos dust can be sucked and collected together with the above-mentioned crushed pieces, so that asbestos dust can be prevented from being scattered.

  However, in any of the above-mentioned conventional techniques, all workers have asbestos-related special education (or asbestos-working chiefs) and special in order to remove existing paint films and tiles (finishing materials for organic materials). A medical checkup (asbestos) is required. Moreover, in order to prevent dust from being scattered, there is a problem that a curing work is required to enclose the work area with a curing sheet or the like, which takes time.

  In addition, when the existing coating film is scraped off with a disc grinder or when the existing tile is crushed with a scraping device, a loud noise is generated, and further, noise is generated due to water discharge sound or operating noise of the negative pressure dust removal device or floor tile removal device. This problem is increased, and there is a problem that it has a great influence on the surrounding environment.

  Moreover, when it is going to scrape off the adhesive between an existing tile and a slab surface (tile attaching surface) with an existing tile, a slab surface will be shaved with an adhesive agent, and a slab surface will become a rough surface. Therefore, it is necessary to work to polish the slab surface with a grindstone (polisher), which is very laborious.

  In particular, in the above-described conventional technology for discharging water, it is necessary to continuously discharge water while scraping the existing coating film or crushing the existing tile, and it is necessary to collect or drain the discharged water. The work is complicated.

  Moreover, in the prior art using the negative pressure dust removal device and the floor tile removal device described above, it is necessary to carry in and out a large device, and the collected dust is disposed of, or after the work is finished or during the work. Since it is necessary to clean the apparatus, work other than actual removal work (preparation before starting work and cleaning up after work) is complicated.

  The present invention has been made in consideration of the above-described conventional problems, and it is possible to easily remove the existing organic material finishing material, and to reduce the noise and labor associated with the construction. It aims to provide a finishing material removal method.

  An organic material finishing material removal method according to the present invention is an organic material finishing material removal method in which an existing organic material finishing material is removed from a base surface. A release agent application step for applying a release agent not applicable to the law, a standing step for allowing the release agent to penetrate into the finishing material and allowing the finishing material to soften, and a removal for removing the softened finishing material. And a process.

  Due to these characteristics, after the standing step, the release agent penetrates into the finishing material of the organic material, and the finishing material that is a hard material (non-flexible) is softened (flexible). In this case, the finishing material can be easily peeled off.

  Moreover, it is preferable that the removal method of the finishing material of the organic type material which concerns on this invention makes the application | coating thickness of the said releasing agent more than the thickness dimension of the said finishing material at the time of the said releasing agent application | coating process.

  As a result, when the release agent is applied to the surface of the finishing material, the release agent penetrates into the finishing material and the finishing material swells, but the finishing material can be made to have a thickness equal to or greater than the thickness of the finishing material. The release agent can be permeated throughout the thickness direction. If the coating thickness of the release agent is less than the thickness dimension of the finishing material, the release agent does not penetrate the entire thickness direction of the finishing material, and the finishing material may not be sufficiently softened.

  In the organic material finishing material removal method according to the present invention, in the standing step, the release agent is interposed not only between the finishing material but also between the finishing material and the base surface. It is preferable to stand until it penetrates into the intermediate layer.

  As a result, the release agent penetrates not only the finishing material but also the intermediate layer after the standing step, and the intermediate layer is softened (flexible), so that the intermediate layer can be easily removed during or after the removal step. It can be removed.

  Further, the organic material finishing material removal method according to the present invention includes, before the release agent coating step, installing a surrounding material on the finishing material so as to surround a range in which the finishing material is removed, and removing the peeling material. In the agent application step, it is preferable to apply the release agent on the inside of the surrounding material.

  As a result, the release agent is applied only to the surface of the finishing material in the inner region of the surrounding material among the large-area wall surface or floor surface, and the release agent is not applied to the surface of the finishing material in the surrounding region. Accordingly, it is possible to soften and remove only the finishing material in a part of the region, and leave the finishing material in the surrounding region without being softened. That is, when the finishing material is partially removed, peeling and deterioration (softening) of the surrounding finishing material due to the release agent are prevented.

According to the organic material finishing material removal method according to the present invention, the existing organic material finishing material can be easily removed. Therefore, the noise accompanying the construction can be reduced and the influence on the surrounding environment can be reduced.
Moreover, since dust is not generated, curing work and the like are simplified, and preparation before the start of work and cleanup after the end of work are easy. Thereby, the effort concerning the removal work of the finishing material of the organic material can be reduced.
In addition, since dust does not occur, even if the existing finishing material contains asbestos, the above-mentioned special education on asbestos, asbestos workers, and special health checkup (asbestos) are not required. It is easy to remove the finishing material.

It is a flowchart figure for demonstrating 1st and 2nd embodiment of the removal method of the finishing material of the organic type material which concerns on this invention. It is a top view of the range which removes the finishing material of the organic type material for demonstrating 2nd embodiment of the removal method of the finishing material of the organic type material which concerns on this invention. It is sectional drawing between AA shown in FIG. It is a compounding table showing an example of a release agent.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a method for removing a finishing material of an organic material according to the present invention will be described based on the drawings.

[First embodiment]
The organic material finishing material removal method shown in FIG. 1 is performed by applying an existing coating film (finishing material of organic material, not shown) containing asbestos from a coating base surface (base surface, not shown). How to remove. Specifically, the above-mentioned coating film is a finishing material such as a wall generally called spray coating, and covers, for example, the surface (undersurface) of a concrete wall (not shown).

  The method for removing the above-described coating film will be described in detail.

First, as shown in FIG. 1, a preparatory process 100 is performed before the coating film removing operation is performed.
More specifically, the release agent to be described later contains a small amount of an organic solvent that does not correspond to the organic law and is low in odor but not odorless. Therefore, a ventilation means in the construction area is secured. In addition, curing is performed on the places where peeling is not performed. In particular, the floor is a three-layer curing, and after the release agent coating step 101 described later, one upper layer is peeled off and collected.

Next, a release agent coating step 101 for applying a release agent not applicable to organic rules is performed on the surface of the existing coating film.
More specifically, the release agent is sprayed onto the surface of the coating film (the surface of the painted wall) using a spraying device (Risin Gun) or the like. In addition, the method of apply | coating a peeling agent on the surface of a coating film using a roller, a brush, etc. is also possible. The coating thickness of the release agent is determined by the standing step 102 described later, and the release agent penetrates throughout the thickness direction of the coating film. The thickness should be sufficient to penetrate the intermediate layer between the film and the coating film.

Next, a standing step 102 is performed in which the release agent permeates the coating film or the like and the coating film is softened.
More specifically, first, after the release agent coating step 101 is completed, the release agent only penetrates through the entire thickness direction of the coating film, and further only for a sufficient time to penetrate into the putty and sealer under the coating film. Leave still. This standing time (open time) is the coating thickness of the release agent, the thickness dimension of the coating film, the thickness dimension of the putty and sealer described above, the permeability of the release agent to the coating film, putty and sealer, and the temperature. Allow to stand for about 16 hours, depending on humidity and humidity.

Next, softening confirmation 103 for confirming the softened state of the coating film is performed.
More specifically, it is confirmed whether or not the coating film is peeled off using a scraper with a blade (gold spatula) or the like. When the coating film is not peeled off, it is allowed to stand for a while (a standing step 102) and waits for the coating film to be peeled off by the confirmation method described above.

When it is confirmed by the softening confirmation 103 described above that the coating film has been softened, a removal step 104 for removing the entire softened coating film is performed.
More specifically, using a kelen tool such as a scraper with a blade, the softened coating film is peeled off together with the putty and sealer, and the existing coating film is removed.

Next, a post-processing step 105 for finishing the base surface from which the coating film has been removed is performed.
More specifically, when the putty remaining on the base surface is small, the remaining putty is scraped off by the nonwoven fabric abrasive (nonwoven fabric polishing step 105A). Thereafter, the base surface is wiped with a waste cloth to remove coating residue, remaining release agent, moisture, and the like (water wiping step 105B). Finally, the base surface is sufficiently dried (drying process 105C).

  On the other hand, when there are many putty remaining on the base surface, after water curing, the remaining putty is scraped off by a water jet (polishing process 105A ′ by water jet). Thereafter, the base surface is wiped dry with a waste cloth to remove the coating film residue, the remaining release agent, moisture, and the like (dry wiping step 105B ′). Finally, the base surface is sufficiently dried (drying process 105C).

In addition, if there is a lot of putty remaining on the ground surface, but water curing is not possible, spray the water on the ground surface where the putty remains by spraying with water spray, etc., soften the putty, and then use a kelen tool such as a scraper with a blade Then, the remaining putty is removed so as to be scraped off (fogging / keren process 105D). Thereafter, a polishing step 105A, a water wiping step 105B and a drying step 105C with the above-described nonwoven fabric abrasive are performed.
Thus, the removal of the existing coating film is completed.
In addition, construction of a new finishing material is performed after this ground surface is completely dried.

  According to the organic material finishing material removal method described above, after the standing step 102, the release agent penetrates into the existing coating film, and the coating film softens (flexes). In this case, the existing coating film is easily peeled off. Therefore, the existing coating film can be easily removed without using a disc grinder or the like, noise due to construction can be reduced, and the influence on the surrounding environment can be reduced. Moreover, since dust is not generated, curing work and the like are simplified, and preparation before the start of work and cleanup after the end of work are easy. Thereby, the effort which concerns on a coating film removal construction can be reduced. Moreover, since asbestos dust is not generated, special education regarding asbestos, asbestos workers, and special health checkup (asbestos) are unnecessary, and the paint film removal work can be easily performed.

  In addition, according to the method for removing the finishing material of the organic material described above, in the standing step 102, the release agent is allowed to stand until it penetrates not only into the coating film but also into the putty and sealer below it, During the removing step 104, the putty and sealer are softened (flexible), and the putty and sealer can be removed together with the coating film. Accordingly, the putty and sealer can be easily removed without damaging the base surface, and the subsequent polishing work can be reduced.

[Second Embodiment]
The organic material finishing material removal method shown in FIG. 1 is a method of removing an existing tile 1 containing asbestos (an organic material finishing material, shown in FIG. 2) and a tile adhering surface 2 (base surface, FIG. 3). 2), and only tiles 1 in a part of the area (tile removal area Y) are removed from tile surface area X in which a plurality of tiles 1 are arranged in a grid as shown in FIG. It is a method to do. Specifically, the tile 1 described above is a floor finish generally called a P tile, and an adhesive layer 4 (intermediate layer) is provided on the upper surface (tile attachment surface 2) of the concrete slab 3 as shown in FIG. It is stuck through.

  A method for removing the tile 1A in the tile removal area Y will be described in detail.

First, as shown in FIG. 1, a preparatory process 100 before performing tile removal work is performed.
If it demonstrates in detail, since the release agent 5 mentioned later contains a small amount of the organic solvent which does not correspond to an organic rule, and it is low odor but is not odorless, the ventilation means of a construction area is ensured. Further, as shown in FIG. 2, a surrounding material 6 that surrounds a range (tile removal area Y) from which the tile 1 </ b> A is removed is installed on the tile 1. The surrounding material 6 is a rod-shaped partition material having a rectangular cross section disposed in a frame shape (rectangular ring) so as to partition the tile removal region Y, and uses a polyethylene backup material that is not affected by the release agent 5. be able to.

  Further, as shown in FIG. 3, when the surrounding material 6 is disposed, the inner surface 6a of the surrounding material 6 is the outer edge of the tile removal area Y (the outer edge of the tile 1A to be removed disposed on the outer periphery of the tile removal area Y). And the surrounding material 6 is extended along the outer edge of the tile removal area Y. In addition, the surrounding material 6 is temporarily fixed (adhered in a peelable manner) to the upper surface of the tile 1 around the tile removal region Y with an adhesive tape (for example, a double-sided tape) or an adhesive. In addition, it is necessary to select the thing of predetermined cross-sectional shape as the surrounding material 6 so that the height dimension H may become more than application | coating thickness T1 of the peeling agent 5 mentioned later, Preferably, the height of the surrounding material 6 is preferable. The dimension H is set to be slightly higher than the coating thickness T1 of the release agent 5.

Next, as shown in FIG. 1, a release agent application process 101 for applying the release agent 5 not applicable to the organic rule is performed on the surface of the tile 1 </ b> A in the tile removal region Y.
If it demonstrates in detail, as shown in FIG. 2, the peeling agent 5 is apply | coated to the inner side of the surrounding material 6 arrange | positioned at frame shape. As shown in FIG. 3, the application thickness T1 of the release agent 5 is such that the release agent 5 penetrates throughout the entire thickness direction of the tile 1A by a stationary process 102 (shown in FIG. 1) described later. Furthermore, the thickness is set such that the release agent 5 penetrates not only the tile 1A but also the adhesive layer 4.

Specifically, the application thickness T1 of the release agent 5 is set to be equal to or greater than the thickness dimension T2 of the tile 1A, and is preferably thicker than the thickness dimension T2 of the tile 1A. For example, when the thickness dimension T2 of the tile 1A is 2 mm, the application thickness T1 of the release agent 5 is set to 3 mm (2 mm (T2) +1 mm).
At this time, care must be taken so that the release agent 5 does not adhere to other tiles 1 (tiles other than the tile removal region Y). If the release agent 5 adheres to other tiles 1, After removing with a dry waste, wipe with a wet waste.

Next, as shown in FIG. 1, a standing step 102 is performed in which the release agent 5 permeates the tile 1 </ b> A and the tile 1 </ b> A is softened.
More specifically, first, after the release agent application step 101 is completed, a sheet (not shown) is covered and protected on the release agent 5 applied on the tile 1 in the tile removal region Y. Then, the release agent 5 is allowed to stand for a sufficient time so as to penetrate the entire thickness direction of the tile 1 </ b> A and further penetrate into the adhesive layer 4. This standing time includes the coating thickness T1 of the release agent 5, the thickness dimension T2 of the tile 1A, the thickness dimension of the adhesive layer 4, the permeability of the release agent 5 to the tile 1A and the adhesive layer 4, and the temperature. Depending on the humidity and humidity, the normal standing time is about 16 hours.

Next, softening confirmation 103 for confirming the softened state of the tile 1A is performed.
More specifically, a part of the sheet (not shown) is peeled off, and a gold spatula or the like is put in the corner of the tile 1A to check whether the tile 1A is peeled off. When the tile 1A is not peeled off, the tile 1A is allowed to stand for a while (a standing step 102) and waits for the tile 1A to be peeled off by the above-described confirmation method.

When it is confirmed that the tile 1A is softened by the softening confirmation 103 described above, a removal step 104 for removing the softened tile 1A in the entire tile removal region Y is performed.
More specifically, first, all the sheets (not shown) are peeled off. Next, the excess release agent 5 remaining on the upper surface of the tile 1A without penetrating the tile 1A is removed by scraping with a gold spatula or the like. Further, the surrounding material 6 is peeled off from the upper surface of the tile 1 and removed. Next, the softened tile 1A is peeled off by scraping the adhesive layer 4 together with a gold spatula or the like, and the tile 1A in the entire tile removal area Y is removed. Note that the adhesive layer 4 may not be removed together with the tile 1A, and the adhesive layer 4 may be removed after the tile 1A is removed.

Next, the post-processing process 105 which finishes the tile sticking surface 2 from which the tile 1A was removed is performed.
This post-processing step 105 is the same as the post-processing step in the first embodiment described above, and cleans the remaining adhesive layer 4 like the “remaining putty” in the first embodiment.
As described above, the removal of the tile 1A in the tile removal area Y is completed.
In addition, a new tile is stuck after this tile sticking surface 2 is completely dried.

  According to the tile removal method described above, after the standing step 102, the release agent 5 penetrates into the tile 1A, and the tile 1A, which is a hard material (non-flexible), is softened (flexible). In the step 104, the tile 1A can be easily removed without being crushed. Therefore, the existing tile 1A can be easily removed without crushing, noise caused by construction can be reduced, and the influence on the surrounding environment can be reduced. Moreover, since dust is not generated, curing work and the like are simplified, and preparation before the start of work and cleanup after the end of work are easy. Thereby, the effort concerning the removal work of tile 1A can be reduced. In addition, since asbestos dust is not generated, special education on asbestos, asbestos workers, and special health checkup (asbestos) are not required, and tile removal work can be easily performed.

  Further, according to the above tile removing method, when the release agent 5 is applied to the surface of the tile 1A, the release agent 5 penetrates into the tile 1A and the tile 1A swells. By setting the coating thickness T1 of 5 to be equal to or greater than the thickness dimension T2 of the tile 1A, the release agent 5 can be permeated throughout the thickness direction of the tile 1A. Thereby, the tile 1A can be peeled off more easily.

  Further, according to the tile removal method described above, in the stationary step 102, the release agent 5 is allowed to stand until it penetrates into the adhesive layer 4 as well as the tile 1A. 4 is softened (flexible), and the adhesive layer 4 can be removed together with the tile 1A. Thereby, the adhesive layer 4 can be easily removed without damaging the tile attaching surface 2, and the polishing work and the like can be reduced after the adhesive layer 4 is removed.

  Moreover, according to the tile removal method described above, the surrounding material 6 surrounding the tile removal region Y is installed on the tile 1 and the release agent 5 is applied to the inside of the surrounding material 6. Among them, the release agent 5 is applied only to the surface of the tile 1A in the tile removal region Y, and the release agent 5 is not applied to the surface of the tile 1 in the surrounding region. Therefore, it is possible to soften and remove only the tile 1A in the tile removal area Y and leave the tile 1 in the surrounding area without being softened. Thereby, peeling and deterioration (softening) of the surrounding tile 1 by the peeling agent 5 can be prevented, performing the partial removal of the tile 1.

Here, the release agent in the present invention will be described.
As the release agent, a solvent that does not correspond to the organic rule that can soften the finishing material (existing coating film or tile 1) of the organic material that is the object to be removed is used. This stripper uses a solvent that does not fall under the specially controlled industrial waste of the Waste Management Law. For example, an inflammable temperature of 70 ° C or higher so as not to become a flammable material, and an organic solvent that does not contain organic solvents corresponding to the organic rules so as not to violate the organic solvent poisoning prevention rules. use.

  More specifically, the main component of the release agent described above includes five-membered lactams or lactones, phenyl alcohol and derivatives thereof, or phenyl glycol and derivatives thereof. Specifically, N-alkyl-2-pyrrolidone, γ -Butyrolactone, benzyl alcohol, alkylene glycol phenyl ether and the like. These may be used alone or in combination of two or more.

  The release agent may contain an ester such as a fatty acid ester or a derivative thereof, a dibasic acid ester, a paraffinic hydrocarbon, a polyhydric alcohol or a derivative thereof. Examples of the polyhydric alcohol include dimethylformaldehyde, dimethyl sulfoxide, polyalkylene glycol alkyl ether, polyalkylene glycol dialkyl ether, and the like.

  Furthermore, it is preferable that the release agent contains a thickener, whereby the coating workability can be improved. Examples of thickeners include cellulose derivatives, polysaccharides, polyvinyl alcohol, acrylic acid organic thickeners, and inorganic thickeners such as silica, kaolin, bentonite, sepiolite, carboxyalkyl cellulose, alkyl cellulose, Examples include hydroxyalkyl cellulose, xanthan gum, and sodium polyacrylate. These may be used alone or in combination of two or more.

In addition, the use of anions, nonions, and amphoteric surfactants contributes not only to improved washing performance but also to the stability of the release agent. Surfactants include carboxylic acid type, sulfonic acid type, sulfosuccinic acid type, sulfate ester type, phosphate ester type, fatty acid ester type, polyoxyalkylene glycol type, polyoxyalkylene alkyl ether, polyoxyalkylene polyhydric alcohol. There are ether, polyoxyethylene polyoxypropylene polymerization type, sorbitan fatty acid ester type, alkanolamide type, aminoacetic acid betaine type, alkylpolyglucoside and the like.
Furthermore, the release agent may contain a small amount of alkylamine, alkanolamine, or the like as a pH adjuster.

    FIG. 4 shows a blending example of the release agent described above. In addition, the table | surface shown in FIG. 4 is a table | surface which showed the mixing | blending of release agent as a percentage, and the unit of the number in a table | surface is "%". However, Example 1-10 of the release agent shown in FIG. 5 is an exemplification, and the release agent of the present invention is not limited to the formulation shown here.

As mentioned above, although embodiment of the removal method of the finishing material of the organic material which concerns on this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning, it can change suitably. It is.
For example, in the second embodiment described above, only the tile 1A in a partial area of the tile surface area X is removed by surrounding the tile removal area Y with the surrounding material 6 and applying the release agent 5 on the inside. Although the method is described, the present invention may be a method of removing the tile 1 in the entire tile surface area X, and in this case, it is not necessary to use the surrounding material 6.

  In the first and second embodiments described above, the release agent 5 penetrates the intermediate layer such as the putty and sealer, or the adhesive layer 4. In the case where the removal of the intermediate layer is unnecessary, or when the intermediate layer can be easily removed without being softened, the intermediate layer does not need to be penetrated by the release agent 5.

  In the second embodiment described above, the application thickness T1 of the release agent 5 is equal to or greater than the thickness dimension T2 of the tile 1A. For example, the release agent 5 does not permeate the entire thickness direction of the tile 1A. However, if the tile 1A can be removed sufficiently, the application thickness T1 of the release agent 5 can be made thinner than the thickness dimension T2 of the tile 1A. Thereby, the usage-amount of the releasing agent 5 can be suppressed and cost reduction can be aimed at.

  Moreover, although the above-mentioned 1st and 2nd embodiment has demonstrated the method of removing the coating film and tile 1A containing asbestos, this invention is a coating film and tile (of organic material) which does not contain asbestos. It is also possible to remove the finishing material. Furthermore, this invention is not limited to the method of removing the coating film of wall finishing material, and the method of removing tile 1 (P tile) of floor finishing material, For example, when removing the tile stuck on the wall, The present invention can also be applied to the case where the coating film applied to the floor is removed, and can also be applied to the case where a finishing material other than the wall or floor is removed.

  In addition, in the range which does not deviate from the main point of this invention, it is possible to replace suitably the component in above-mentioned embodiment with a well-known component, and you may combine the above-mentioned modification suitably.
