Description

  The present invention relates to a method for processing a tombstone, and more specifically, the occurrence of an iris phenomenon that is likely to occur on the surface of a tombstone that is a stone structure, particularly a mirror-finished tombstone, characters and line drawings carved in the tombstone, etc. It prevents the occurrence of various tombstone deterioration such as chipping and weathering of the gravestone and weathering of the tombstone itself, and eliminates the iris phenomenon that occurred on the surface of the tombstone, etc. After removing dirt, etc., and reproducing it, it prevents the occurrence of iris phenomenon and deterioration, does not cause wet color, and in particular, does not cause wet color in the engraving part, natural color and natural texture The present invention relates to a method for processing a tombstone for carrying out a deterioration prevention process and a regeneration process for the tombstone.

In general, a tombstone causes deterioration such as dirt and weathering due to various factors. Of these, deterioration due to external factors such as dirt and weathering may be caused by rain traces caused by the transmission of rain, adhesion of dirt components from the fallen leaves of surrounding trees, or acidic substances in the air or rainwater. Some of these are caused by chemical erosion of the surface due to the above.
On the other hand, the contamination due to internal factors includes, for example, those that occur when iron contained in the tombstone itself is oxidized by an acidic substance that has permeated from the outside and floats on the surface. And since such dirt cannot be removed by simple cleaning, the appearance of the tombstone is often greatly impaired.

For this reason, conventionally, a tombstone surface treatment method for preventing various stains as described above has been proposed for tombstones made of various stone materials.
As such a tombstone surface treatment method, for example, a method of forming a surface protective film on the surface of the tombstone has been proposed in order to prevent the occurrence of dirt on the tombstone after installation, for example, to prevent it actively ( For example, see Patent Documents 1 and 2).

For example, in Patent Document 1 described above, after the surface of the tombstone is sufficiently washed and dried, a surface protective film such as a protective film having a siloxane bond is formed on the surface of the tombstone, and a matte film such as an alkoxy film is formed on the engraved character portion. There has been proposed a method for protecting the surface of a tombstone that forms a matte film obtained by applying a character protective agent containing silane or a hydrolyzate thereof and colloidal silica and then curing it.
In Patent Document 1, when a matte film is formed on an engraved character portion, after washing and drying, first, the engraved character portion is embedded with a clay filling, and then a surface protective agent is applied to the entire surface of the tombstone. Curing to form a surface protective film, then removing the padding on the engraved character part, applying a character protective agent and curing to form a matte film to prevent the engraved character from becoming difficult to read Yes.

In Patent Document 1, as the tombstone, for example, white granite, black granite, komatsu stone, basalt, marble, sandstone, and the like are listed. Examples include prevention, maintenance of luster of black granite, and special surface color of Komatsu stone, that is, surface protection treatment for maintaining the original green color.
Further, in Patent Document 2, an antifouling tombstone in which a titania film forming precursor solution is applied to the surface of a cemetery stone, and the cemetery stone material to which the precursor solution is applied is baked to form a titania film on the tombstone surface. A method for producing antifouling tombstones has been proposed.

JP-A-10-61258 JP 2002-242486 A

By the way, in recent years, a phenomenon called an iris phenomenon in which the surface of a tombstone, in particular, the surface of a granite tombstone such as a white granite or a black granite with a mirror finish has a so-called rainbow color has been regarded as a problem. This iris phenomenon is said to be a precipitate caused by silica in the air and is extremely hard. Therefore, in order to remove this iris phenomenon, a troublesome removal method such as polishing the tombstone surface is required. It was done. Even if this removal method takes time and effort and resolves the iris phenomenon, it is a troublesome matter that it recurs relatively easily.
However, the tombstone after installation has a religious meaning, and peeling the tombstone surface to remove the iris phenomenon that has occurred on the surface of the tombstone after installation will result in a religious tombstone. It was not preferred because it would cause scratches, and there was a need to remove the iris phenomenon that occurred without peeling.

By the way, in the tombstone surface protection method described in Patent Document 1, details on cleaning / drying as a pretreatment for prevention of iris phenomenon and wet color and formation of a surface protective film and a matte film are not mentioned at all. As can be seen from the above, it cannot be said that the iris phenomenon on the surface of the tombstone and the occurrence of wet color are sufficiently prevented, and the iris phenomenon that has occurred on the surface of the tombstone cannot be removed or eliminated. was there.
Moreover, in the tombstone surface protection method described in Patent Document 1, since a matte film is formed on the engraved character portion, it is possible to prevent the engraved character from becoming difficult to read. There was a problem that it was necessary to embed it with clay stuffing, which was troublesome.
Moreover, in the manufacturing method of the antifouling tombstone described in Patent Document 2, a titania film is formed on the tombstone surface to ensure the antifouling property of the tombstone surface. In addition, depending on the film thickness, there is a problem in that an iris phenomenon occurs on the tombstone surface.

  The object of the present invention is to eliminate the above-mentioned problems of the prior art, and to the tombstone, which is a troublesome phenomenon as described above, which tends to occur on the surface of a tombstone that is a stone structure, particularly a mirror-finished tombstone.

In particular, it is possible to finish in a natural color or natural texture without causing wet color in the engraving portion.

It is a schematic block diagram of the tombstone which is the application object of the processing method of the tombstone which concerns on one Embodiment of this invention. It is a flowchart which shows the procedure of the processing method of the tombstone which concerns on embodiment.

Hereinafter, a method for processing a tombstone according to an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a schematic configuration of a tombstone to which the tombstone processing method according to the present embodiment is applied. In FIG. 1, 1 is a lower base stone installed on a caroten (not shown) in which an urn is stored, 2 is a censer placed on the front surface of the lower base stone 1, and 3 is on the lower base stone 1 The basin stones 4 are placed on the lower talus stone 1 so that the basin stones 4 are located on the front surface of the basin stone 3, and 5 is placed on the basin stone 3. Upper stones 6 and 6 are meteorites placed on the upper stone 5. As is well known, engraving characters (not shown) such as a house name are arranged on the front surface of the meteorite 6.

As a material (stone material) constituting the tombstone, for example, white granite, black granite, komatsu stone, Emochi stone, basalt, marble, sandstone and the like are also used.
And depending on the type of these stones used, there are some differences in the tombstone processing method according to this embodiment, but basically, as will be described later, the cleaning process, the coating process and the protective film forming process. Since each process is carried out in this order, a typical example will be described in the case of a black granite with a mirror finish, which often causes discomfort due to the occurrence of an iris phenomenon as a deterioration of a tombstone.

First, an overview of a method for processing a tombstone according to the present embodiment will be described.
In this embodiment, first, as a tombstone processing method of the present invention, a tombstone processing method that is performed to remove and eliminate deterioration such as an iris phenomenon that has occurred on the surface of the tombstone will be described.
The iris phenomenon that is the object of processing here is basically one that may occur in any of the components that make up the tombstone. Needless to say, the part to be made is the front side of the tombstone or the front side part of the side face.
Further, as deterioration other than the iris phenomenon, it is preferable to include dirt on the surface of the stone material of the tombstone and chipping of a sculpture part including characters.
In the following explanation, a case will be described in which basic processing is performed for all of the components of the tombstone. However, in practice, the portion to be processed may be appropriately determined in consideration of the expenses that can be spent. Needless to say.

  It should be noted that the tombstone processing method according to the present embodiment, which will be described below, is most preferably implemented immediately after the completion of the production of each component before the tomb, but in practice, after the tomb. Therefore, it is presumed that the case where the grave is carried out in the grave place is high in frequency. In this case, if consent is obtained in various points, it may be preferable to temporarily dismantle each component of the tombstone in the grave and implement it in an environment where the work is easier to carry out.

In the tombstone processing method according to the present embodiment to be described below, a case where the tombstone is implemented in the state of the tomb after “after the tomb” as described above, which is presumed to be performed frequently, will be described as an example.
The tombstone processing method according to the present embodiment is roughly divided as shown in FIG.
(1) A cleaning process (step 10) for cleaning the surface of each component of the tombstone to be processed;
(2) A process of forming a special tombstone surface protective film on the surface of each component of the cleaned tombstone (step 20), and (3) A process of performing an inspection after completion (step 30)
These steps are performed.

The above-described procedure (1), that is, step 10 is a step of sufficiently cleaning the surface of the above-mentioned component (stone) of the tombstone.
This cleaning process usually removes foreign matter on the surface of the tombstone components, such as dirt and oil adhering to the surface and oil or dirt soaking into the inside from the surface with a release agent. The removal agent treatment process to be removed (hereinafter simply referred to as the peeling process) (step 12), the subsequent cleaning process with the cleaning agent (step 14), and the subsequent drying process (step 16). is there.
In the case of a tombstone that has been "long after the tomb" for a long time, before the cleaning process, i.e., before applying the release agent, on the surface of the stone material, such as dead leaves deposited on the stone surface of the tombstone. It is preferable to remove previously generated adherends such as mold and moss.

In this stripping step (step 12), a predetermined stripping agent is diluted to a predetermined concentration and used, and the diluted stripping agent is applied to the entire surface of each component of the tombstone by brushing or spraying with a spray gun. To do. Then, after applying the release agent, a wrapping material (thin plastic sheet) is wound around the application surface to prevent rapid drying, and the action of the release agent is continued for a predetermined time. About this duration, you may determine suitably.
Thus, in the peeling step, foreign substances such as dirt and oil that have been peeled off and decomposed from the surface and inside of the stone by the release agent can be raised.

  The release agent used here preferably contains isopropyl alcohol, minerals, and sodium hydroxide, and more preferably contains a stray aid, a thickener, potassium hydroxide, and a surfactant. The cleaning agent is preferably a neutral detergent. For example, R coat release agent SSU (trade name) (manufactured by Rect Japan Co., Ltd.) and the like can be mentioned. When this release agent is used, it is applied to the surface of the tombstone stone, and then covered with a wrapping material or the like to prevent drying, and is kept for about 15 minutes to 1 hour, usually about 30 minutes.

Stones used for tombstones are soaked in heavy oil before transportation, or lifted after application, or coated with heavy oil, etc. on the surface, so that they will not be damaged or chipped during transportation. In the case of imports from Japan, they are transported by ship while immersed in heavy oil, etc., so foreign matter such as oil and dirt adheres to the surface of the stone even before it is finished in the tombstone. Often soaked inside. In the case of a tombstone that has been "after the tomb" for a long time, it is a matter of course that foreign matter such as oil or dirt adheres to the surface or penetrates from the surface.
In view of such a phenomenon, the present inventors have found that this peeling process is important for the treatment of a tombstone, both when a new grave is built and when it is “long after the grave”. did.

In the peeling process, after the action of the peeling agent is continued for a predetermined time, the above wrap is peeled off and the process proceeds to a cleaning process (step 14) for each component of the tombstone.
In the cleaning process, clean the foreign matter such as dirt and oil that has been raised on the surface of the tombstone stone in the peeling process with a cleaning device such as a hand cleaner or hand polisher, and then use a neutral detergent solution. Wash and finally rinse with water. In this way, foreign matters such as dirt and oil on the surface of the tombstone and the remaining release agent can be removed as well as the detergent solution.
In this cleaning step, it is preferable to sufficiently clean the surface of the tombstone and the interior of the stone near the surface. The reason for this is to improve the adhesion of the surface protective film to be formed later, promote the protective effect, and maintain it for a long period of time. Therefore, after confirming the surface of the tombstone after washing, it is preferable to carefully wash it if necessary if dirt or oil remains.
The type of neutral detergent used here, the concentration used, and the like may be appropriately determined based on experience values.

When washing with the neutral detergent is completed in the washing process, the neutral detergent solution and the like used for washing are washed away with clean water, and then the process proceeds to the drying process (step 16).
In this drying step, the surface of the tombstone and the inside of the stone near the surface may be sufficiently or completely dried naturally. The dryness of the tombstone affects the adhesion of the surface protective film that is formed later, promotes the protective effect of the surface protective film, and affects its sustainability. Because it gives.
Therefore, the drying process is the most important process, and it is preferable to dry for a predetermined time required for complete drying, for example, 15 hours or more in the case of a normal tombstone.

After the cleaning of each component of the tombstone is completed by the above process, after confirming that it is completely dry, after finishing the surface with sandpaper etc. if necessary, the entire surface including the bottom of each component of the tombstone The process proceeds to a step (step 20) of forming a surface protective film using a surface protective agent containing alkoxysilane as a main component, that is, an inorganic glass coating agent, as will be described later.
In this surface protective film forming step (step 20), the surface protective agent mainly comprising a silane compound such as alkoxysilane supplied on the market is selected according to the type of stone to be treated, etc. It is important to select and use one having suitable characteristics.

  More specifically, depending on the type and state of the tombstone to be processed by the tombstone processing method according to the present embodiment, various types of surface protective agents mainly composed of alkoxysilanes supplied to the market are available. It is necessary to prepare a surface protective agent of the formula (step 22). For example, in the practitioner or practitioner of the tombstone processing method according to this embodiment, pay close attention to prepare surface protection agents of various prescriptions, and actually perform treatment experiments using them. An optimum inorganic glass coating agent may be prepared.

Examples of the surface protective agent mainly composed of a silanized product such as alkoxysilane include (1) a small amount of dimethylsilane, diethylsilane and diphenyldichlorosilane added to monomethylsilane, monoethylsilane and monophenyldichlorosilane, and water. A tri-functional condensate (RSiO _1.5 ) and a bifunctional condensate (R ₂ SiO) obtained by hydrolysis with addition of water, a silicone varnish solution dissolved in a solvent such as xylene, sodium acetate and octylic acid A composition containing a curing accelerator such as zinc, tetrabutyl titanate or aluminum acetylacetonate; (2) Modified by adding an organic resin such as alkyd resin, epoxy resin, acrylic resin or urethane resin to the condensate. A modified silicone varnish solution obtained by dissolving this in a solvent such as xylene and the above-mentioned An inorganic glass coating agent having a composition containing a cured accelerator is used.

  For example, as a specific inorganic glass coating agent, an inorganic glass coating agent containing alkoxysilane as a main component and further containing N-propyl alcohol and aluminum chelate is preferable, and alkoxysilane 85-95%, N- An inorganic glass coating agent containing 3 to 10% propyl alcohol and 3 to 10% aluminum chelate is more preferable. As such an inorganic glass coating agent, "Ear Coat H" or "Ear Coat G" manufactured by Lecto Japan Co., Ltd. can be used. This “R Court H” contains 90% of alkoxysilane, 5% of N-propyl alcohol, and 5% of aluminum chelate.

  By the way, the application of the surface protective agent in the step of forming the surface protective film (step 24 in FIG. 2) forms a film having a very thin uniform thickness on the entire surface of each component of the tombstone for which the surface protective agent is treated. It is necessary to. Therefore, in the iris phenomenon processing method according to the present embodiment, a small amount of a surface protective agent is taken on a cloth (cleaning cloth such as a knitted towel) and applied to the surface of each component of the tombstone, immediately. The operation of wiping with another dry cloth is very important.

  The meaning of this operation is “to take a small amount of surface protective agent on the waste cloth and apply it to the surface of each component of the tombstone” by effectively using the necessary and sufficient amount of surface protective agent without loss. This means that only the amount that can be soaked in from the surface of the stone that makes up the tombstone is supplied, and after applying a small amount of surface protection agent in this way, quickly wiping it with another waste cloth while wiping it in the stone This is because it can be stably present on the surface of the stone by soaking it into the roots (also called “footing”).

  In the process of wiping off the surface protective agent, what is as important as the above-mentioned “sticking” is that there is no unevenness in wiping. Needless to say, this is nothing but the uniform thickness of the surface protective film to be formed. In particular, it is possible to form a thin film having a uniform thickness of about 10 μm.

Considering the circumstances of the operation site, the fact that it is possible to carry out such work with precision (thin film formation) should be a work (operation) method worthy of adoption in practice. .
In addition, about the measurement result of the above-mentioned thickness, it is preferable to confirm and confirm the work result for each practitioner in the desk test, and thus the reliability for the operation can be maintained at a very high level. It becomes.

  In the drying step (step 26) after the wiping operation is completed, it is preferable to take a sufficient drying time of about 3 to 4 hours in a normal climate. This drying is preferably natural drying, and it is important not to perform heating or the like. Therefore, when performing work outdoors (that is, in a graveyard or the like), it is necessary to select a day on which sufficient “sunny” time can be confirmed in consideration of the drying time. This is because it is highly possible that the surface protective agent will be whitened and have poor performance when exposed to water (that is, rain) during drying.

When the drying process (step 26) is completed, the processing method according to the present embodiment is completed. However, whether or not the process is completed as scheduled (specifically), in particular, deterioration of an iris phenomenon or the like occurs. In the case of a tombstone, it is necessary to first check whether or not deterioration such as disappearance of the iris phenomenon has been removed or regenerated (step 32 in step 30 in FIG. 2).
The inspection here is carried out by a visual inspection at the site and a method of lightly touching and confirming.
The inspection after the elapse of the predetermined time described as step 34 is performed when an observation time predetermined according to the type of stone material, the execution time, etc. elapses.

Prior to the step of forming the surface protective film with the surface protective agent, it is also preferable to use an aqueous primer or an oily primer for the base.
About the application process in this case, it is good to use the method according to the application process at the time of forming a surface protection film.
Such primer treatment will be described later.

  According to the tombstone processing method according to the above embodiment, the molecular structure of the surface protective film formed on the surface of each component of the tombstone has a siloxane bond (Si—O—Si) similar to glass or quartz. In addition to exhibiting excellent corrosion resistance, water resistance, chemical resistance, friction resistance, and weather resistance against chemically inert and pH 2 acids, the surface protective film has a high hardness (pencil hardness: equivalent to 11H to 15H) Therefore, it is possible to improve the strength of the tombstone surface, make it difficult to get scratches, etc., and to reinforce the edges of characters and line drawings etc. of the tombstone sculpture part, It is possible to realize a processing method capable of easily removing the deterioration and suppressing the recurrence of deterioration such as an iris phenomenon or the like, dirt on the gravestone surface, chipping of a sculpture part including characters and line drawings, etc. over a long period of time.

  In the tombstone processing method according to the above embodiment, the surface protective film formed on the surface of each component of the tombstone initially shows water repellency for a while (approximately 2 months), but thereafter gradually becomes hydrophilic. It changes to exhibit. In this way, the surface protective film formed on the surface of each component of the tombstone has the effect of allowing the water to easily enter between the film and the dirt, thereby raising the dirt. , There is an advantage that leads to the effect of removing dirt at an early stage.

  In addition, since the surface protective film formed by the tombstone processing method according to the above embodiment has a property of allowing air and moisture to permeate, the surface protective agent used in the tombstone processing method according to the above embodiment, It can be used to form a surface protective film by coating not only stone materials with low water permeability such as granite but also marble, sandstone (relatively high water permeability) and wood. In addition, the said surface protective film shows the outstanding weather resistance.

As described above, in the case where the surface of the tombstone stone is mirror-finished, immediately after the cleaning process, an application step of applying a surface protecting agent to the surface of the tombstone stone material that has been cleaned, that is, dried. However, the present invention is not limited to this as described above.
In particular, when the surface of the tombstone is not mirror-finished, an aqueous primer and an oily primer are further applied to the surface of the tombstone that has been cleaned (after drying) prior to the surface-protecting agent application step. It is preferable to have a primer coating step of coating at least one of the above at least once. For example, in the case of an aqueous primer, this primer application step is preferably performed by repeating the application and drying a plurality of times, particularly 2-3 times, on the surface of the tombstone, and in the case of an oily primer, the surface of the tombstone More preferably, the coating and drying are repeated once or twice.
In the present invention, the water-based primer and the oil-based primer may be used alone or in combination, and there is no particular limitation on which one to use, but it is preferable to use the water-based primer because it does not easily become a wet color.

As described above, the surface of the tombstone can be repelled by applying a surface protective agent to the surface of the tombstone after applying and drying the aqueous primer and / or oily primer to form a surface protective film. In addition, it is possible to prevent the surface of the tombstone from becoming wet.
If the surface of the tombstone is not mirror-finished, or if the tombstone easily absorbs the surface protective agent, the surface of the tombstone will blur and the surface color of the tombstone will become wet. Even if the deterioration of the iris phenomenon, etc. could be prevented, it resulted in lack of decorativeness, but by applying a primer treatment to the surface of the tombstone before applying the surface protective agent, Generation of a wet color on the surface can be prevented and a good surface protective film can be formed.

In addition, as an aqueous primer, it is preferable to contain a mineral and methyl alcohol as a main component, Furthermore, minerals 40-60%, methyl alcohol 20-30%, 2-ethylhexyl glycol 2-10%, surfactant 2-10 %, A neutralizing agent 2 to 10%, an additive 2 to 10% and a stabilizer 2 to 10% are more preferable. Specifically, as such an aqueous primer, “Ear Coat aqueous primer” manufactured by RECT JAPAN Co., Ltd. can be used. This product contains 50% mineral, 25% methyl alcohol, 5% 2-ethylhexyl glycol, 5% surfactant, 5% neutralizer, 5% additive and 5% stabilizer.
In addition, the oil primer is not particularly limited, but depending on the coating amount, it may be slightly wet color, although it is water repellent when it is particularly large, so that it is difficult to become wet color as much as possible, Specifically, “Ear Coat Oil Primer” manufactured by RECT JAPAN Co., Ltd. can be used.

Also, even if the surface of the tombstone is mirror-finished, the tombstone (meteorite, etc.) has a sculptured character part that includes characters such as the name of the house, so the sculpture part on the surface of the tombstone In addition, it is preferable to have a primer application step of applying at least one of an aqueous primer and an oily primer only once to the cleaned (after drying) engraving portion before the surface protective agent application step. .
In this primer coating step, it is preferable to apply an aqueous primer and / or an oily primer and dry only on the engraved portion on the surface of the tombstone by the same coating method as that for primer coating on the tombstone surface.

Thus, after applying and drying a water-based primer and / or oil-based primer only on the sculpture part on the surface of the tombstone, applying a surface protective agent to the entire surface of the tombstone and drying to form a surface protective film, Although the engraving portion on the surface repels water, the gloss can be suppressed and the color of the engraving portion can be prevented from becoming wet.
Since the sculpture part on the surface of the tombstone cannot be mirror-finished, the sculpture part easily absorbs the surface protection agent, the surface protection agent bleeds on the sculpture part, and the color of the sculpture part becomes wet color Even if the deterioration could be prevented, the result was that the decorative property was lacking. However, by applying the primer treatment only to the engraved part before applying the surface protective agent, the engraving part is glossy or wet. The generation of color can be prevented and a good surface protective film can be formed.
In addition, what was mentioned above can be used as an aqueous primer and an oily primer.

  In addition, when forming the surface protective film by the method for processing a tombstone according to the present embodiment, as disclosed in Patent Document 1, in order to protect the engraved portion of the tombstone, the engraved character portion is filled with a padding such as clay. After embedding, it may be applied with a surface protective agent and cured to form a surface protective film, but after removing the embedded padding, it is necessary to apply a different surface protective agent to the engraved part separately However, in the present invention, there is no need to perform such a troublesome method.

Hereinafter, preferred embodiments of the present invention will be described in detail.
It should be noted that the tombstones made of black granite to be processed here have an iris phenomenon that causes an unpleasant appearance to at least a part of the tombstone. In addition to the removal, the iris phenomenon is processed for the purpose of suppressing recurrence over a long period of time.

Example 1
In this embodiment, only the meteorite 6 which is the main part of the tombstone is taken out, and the method for processing the iris phenomenon of the tombstone according to this embodiment is applied.
Here, “Ear Coat H” manufactured by Rect Japan was used as the surface protective agent. This product contains 90% alkoxysilane, 5% N-propyl alcohol and 5% aluminum chelate.

  First, only the meteorite 6 is taken out of the tombstones composed of the black granite and shown in FIG. 1 as shown in FIG. 1 and includes the bottom surface. The entire surface was cleaned and then dried. Subsequently, as described above, the surface protective agent includes the bottom surface of the meteorite 6 and the engraved character portion using a method in which a small amount of the surface protective agent is taken into the waste cloth and applied to the surface of each component part of the tombstone. A surface protective film was formed by applying to the entire surface and curing.

The meteorite 6 made of black granite coated with the surface protective film of Example 1 as described above and the meteorite made of black granite without surface protection (Comparative Example 1) were each outdoors for 8 months. After exposure, the surface condition of these meteorites was observed visually.
As a result, in the meteorite of Example 1, the iris phenomenon was completely removed, the recurrence was suppressed over a long period (observation period: 8 months), and the glossiness peculiar to black granite was maintained. In the meteorite of Comparative Example 1, the iris phenomenon further increased in intensity, and the gloss was lost and the whitish color was changed.

(Example 2)
In the present embodiment, the iris phenomenon processing method according to the present embodiment is applied not only to the meteorite 6 which is the main part of the tombstone but also to all the tombstone constituent members.
First, the lower base stone 1, the incense burner 2, the middle base stone 3, the water basin 4, the upper base stone 5 and the meteorite 6 (that is, all the components of the tombstone) shown in FIG. The entire surface including the bottom surface of) was cleaned and then dried. Subsequently, the same surface protective agent as in Example 1 described above was applied to the entire surface including the bottom surface of the tombstone constituent member by the same method as in Example 1 and cured to form a surface protective film.

  Next, the tombstone having the surface protected was constructed by assembling the tombstone constituent member on which the surface protection film as described above was formed as shown in FIG. 1 described above.

  After exposing the tombstone made of black granite coated with the surface protective film of Example 2 as described above to the outdoors for one year, the surface state of each component of the tombstone was visually observed. As a result, in the tombstone of Example 2, the iris phenomenon is completely removed in any of the constituent parts, the recurrence is suppressed over a long period (observation period: 1 year), and the gloss unique to black granite is maintained. It had been.

  (Example 3) First, the entire surface including the bottom surfaces of two marble plates was washed and then dried. Subsequently, using the same surface protective agent as in Example 1 described above, this surface protective agent is applied to the entire surface including the bottom surface of the marble plate by the same method as described above and cured to form a surface protective film. did.

  Of the two marble plates coated with the surface protective film of Example 3 as described above, one of the marble plates is 9.8 in 9.8 accelerated weather resistance in the JIS K5400 (1990) paint general test method. .1 A 200-hour accelerated weathering test was conducted with a sunshine arc lamp type, and the appearance was visually compared with a marble plate coated with the remaining surface protective film not yet tested. As a result, there was no difference in appearance between the marble plate after the accelerated weathering test and the marble plate that had not been tested.

  As described above in detail, according to the present invention, it is possible to provide a method for processing deterioration of a tombstone iris phenomenon or the like that can easily remove the iris phenomenon and suppress recurrence over a long period of time.
