Description

  The present invention relates to a spreading material suitable for restoration of works of art and cultural properties, and a method for manufacturing the same.

In general, when coloring is performed using a pigment or decoration is performed by pasting a foil such as a gold foil, a method of coloring or supporting a gold foil on a support material made of wood or paper is employed.
In this case, it is necessary to use a spreading material for the purpose of attaching the surface decoration to the support material, and animal glue, vegetable glue, and synthetic glue are known as such spreading materials.
On the other hand, although the surface decoration using such a spreading material depends on the storage state, it will be damaged over time, so that it needs to be repaired.
Usually, damage to artworks and cultural assets occurs in the form that the adhesive strength of the glue, which is the spreading material, is reduced, and the surface decoration is lifted or peeled off from the support material.
In this case, as a new spreading material, for example, acrylic resin or beef glue mainly made of cow is used to adhere the surface decoration to the support material again.

When restoration is performed using an acrylic resin as a new spreading material, the acrylic resin is surely deteriorated with the passage of time, although defects such as deformation and shrinkage of the acrylic resin do not occur during drying.
In addition, when repairing the surface decoration using acrylic resin, if the acrylic resin used for the repair deteriorates and then needs to be repaired again, the acrylic that has deteriorated from the surface decoration that is the object to be repaired There was a problem that the resin could not be removed and the restoration could not be performed.

In addition, when repairing using beef glue as a new spreading material, particular attention was required in handling.
Normally, cow glue is gelatin made from collagen extracted from cow skin and bone, and such gelatin is made into a sol by macromolecules of protein holding water molecules inside.
When the surface decoration that has been lifted up from the support material is diluted with water and applied or sprayed on the surface of the surface decoration, the beef glue deforms and contracts as the moisture evaporates. However, the damage to the object to be repaired may be further deteriorated, or in the worst case, the surface decoration may be peeled off.
For this reason, when restoring works of art and cultural assets, the surface decoration is supported by injecting sol beef glue into the gaps of the surface decoration raised from the support material one by one using a syringe or the like. It was necessary to re-adhere to the material.
Several inventions have been disclosed for the purpose of solving such problems.

According to the first aspect of the present invention, when the adhesive substance is applied to or sprayed on the surface of the object to be repaired by using natural fermented glue or fish, the adhesive component smoothly penetrates into the interior. It has the effect that it can be made.
As a result, the object to be repaired can be repaired by simply applying or spraying the object according to claim 1 sol-formed using water to the object to be repaired. That is, by using the spreading material according to claim 1, it is possible to significantly reduce the time required for the repair work as compared with the case of using conventional cow glue.
Further, since the spreading material according to claim 1 is supplied to the object to be repaired, it is biodegraded with the passage of time and finally disappears completely from the surface decoration that is the object to be repaired. The restoration of the surface decoration using the spreading material according to 1 is possible.
As a result, it is possible to permanently preserve the surface decorations of works of art and cultural properties by repeating the restoration using the spreading material according to claim 1.
Moreover, since the spreading | diffusion material of Claim 1 contains sodium (Na), phosphorus (P), and potassium (K) which are impurities which have a hygroscopic property in a density | concentration higher than normal cow glue, this The object to be repaired that has been repaired using the spreading material can continuously take in moisture from the atmosphere after the repair is completed.

Since ancient times, people have found that proteins are sticky and have been used as glue or adhesives for surface decoration as glue.
Conventionally, when damage such as surface decoration of arts and cultural assets has been lifted or peeled off, it has been repaired using cow glue or acrylic resin.
However, beef glue is a gelatin produced using collagen extracted from cattle with high purity as a raw material, and since such gelatin has a large molecular weight, it is an adhesive component when applied or sprayed on the surface of the object to be repaired. There is a problem that not only gelatin does not penetrate into the interior of the object to be repaired, but also the surface of the object to be repaired is deformed and contracted during drying to further damage the surface decoration.
For this reason, conventionally, when repairing using beef glue, it has been repaired by injecting solded beef glue using a syringe or the like into the gap between the surface decoration that floated and its support material, This method is very workable and cumbersome.

Therefore, the inventor paid attention to the fact that some of the old art and architecture techniques have sustained the adhesive force using microbial-derived proteins, and as a result of earnest research, the restoration of adhesive components The present inventors have found a spreading material that has high penetrability from the surface of the object into the interior, and is finally biodegraded and disappears from the object to be repaired, and a method for manufacturing the same.
Hereinafter, a spreading material and a manufacturing method thereof according to the best mode of the present invention will be described in detail with reference to FIGS. 1 to 4.

FIG. 1 is a flowchart showing a method for manufacturing a spreading material according to an embodiment of the present invention.
The manufacturing method 1 of the spreading material according to the present embodiment is roughly manufactured as shown in FIG. 1, in a microbial species manufacturing process (step S1) for manufacturing microbial species 9 from fish, and in step S1. Fermentation liquid manufacturing process (step S2) which manufactures the fermented liquid 15d from the microorganisms 9 and the glue liquid 12b which made the cow glue sol with water, the fermentation liquid 15d manufactured in step S2, and the cow glue with water This is constituted by a mixing, forming and drying process (step S3) for producing the final spreading material 17b from the concentrated glue liquid 12c which is concentrated by applying heat treatment to the glued glue liquid 12b.
Below, step S1-S3 is demonstrated in detail, referring FIG. 2 thru | or 4. FIG.

2 (a) to 2 (c) are conceptual diagrams showing a microbial species production process according to an embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the part same as what was described in FIG. 1, and the description about the structure is abbreviate | omitted.
In the microorganism species production process (step S1) according to the present embodiment, first, as shown in FIG. 2 (a), 1 kg of all the freshwater or seawater fish 3 (ara, fillet, built-in) 1kg. Water 4; 200 cc is added to the mixture, and heated for about 15 minutes with low heat to obtain a heat-treated raw material 7. In this way, by preheating the fish 3, it is possible to suppress the propagation of spoilage bacteria.

Subsequently, as shown in FIG. 2B, the heat-treated raw material 7 is accommodated in a ceramic container 5, and the opening 6 is sealed with a seal 6 made of a material having a slow air permeability such as Japanese paper or cloth. Then, it is placed on the ground surface 8 with ventilation that is not exposed to direct sunlight, for example, under the floor of the first floor of a Japanese-style building, in the soil, in a warehouse, etc., and is naturally fermented for at least two years. Also in the other processes described below, when “the ground surface 8 with ventilation that is not exposed to direct sunlight” is described, for example, it indicates the floor under the first floor of a Japanese-style building, the soil, and the warehouse.
In this embodiment, the undesirable action of microorganisms under aerobic conditions is referred to as `` rot '', the microorganisms grow under anaerobic conditions or semi-anaerobic conditions, and the target useful metabolites and The action of producing enzymes is called “fermentation” to distinguish them.

In this case, it was generated in the ceramic container 5 when fermentation progressed while preventing the active exchange of air into the ceramic container 5 by using Japanese paper or cloth having a slow air permeability as the seal 6. Gas can be released slowly to the outside.
As a result, the inside of the ceramic container 5 becomes a semi-anaerobic state, and microorganisms (for example, lactic acid bacteria) that proliferate using protein as a nutrient source can be propagated predominantly.
In addition, the microorganisms referred to in the present embodiment indicate yeasts, molds, bacteria, etc. that normally live in nature, and the microorganisms that propagate in the ceramic container 5 in step 1 are not necessarily one type. .
In addition, by producing microbial species 9 using all of the freshwater or seawater fish 3 as a raw material, the microbial species 9 contains a large amount of sodium (Na), phosphorus (P), potash (K), etc. Have

Then, during the two-year natural fermentation shown in FIG. 2 (b), the salmon fillet 10 with respect to the total amount of the heat-treated raw material 7 composed of fish 3; 1 kg, water 4; 200 cc, twice a year. About 200 g of (skinned may be used) is added to obtain microbial species 9. (See FIG. 2 (c).)
In general, since salmon is high in protein, adding such salmon fillets 10 to the heat-treated raw material 7 during natural fermentation makes it possible to add protein, among other microorganisms that inhabit the ceramic container 5. It has the effect that it is possible to promote the growth of microorganisms that grow as nutrient sources.
This has the effect of promoting the production of proteolytic enzymes by microorganisms.
Moreover, since the lipid contained in the salmon fillet 10 is low in fish, the use of the salmon fillet 10 as a nutrient source for microorganisms allows lipid (oil) to be mixed in the microorganism species 9 in the microorganism species production process (step S1). This has the effect of minimizing the amount of work.
As a result, when the spreading material 17b is manufactured using the microbial species 9, it is possible to prevent the affinity with the aqueous pigment from being damaged by the oil.

In addition, if the total amount of the fillet 10 added to the total amount of the heat-treated raw material 7 does not fluctuate significantly, the smaller fillet 10 is added to the ceramic container 5 at a frequency of twice or more per year. Also good. In this case, however, care should be taken because there is a risk of spoilage due to various bacteria depending on the season.
In addition, by continuously adding 200 g of salmon fillet 10 twice a year, microorganisms in the ceramic container 5 will be subcultured, and the activity of specific microorganisms will be maintained. The naturally fermented microbial species 9 can also be used without difficulty in the production of the spreading material 17b.
The microbial species 9 produced in the process as described above supplies living microorganisms for the next fermentation broth production process (step S2) and is a nutrient source essential for the propagation of microorganisms, such as sodium (Na), It has the effect of supplying phosphorus (P), potassium (K) and the like.

Moreover, the work which manufactures the heat-processed raw material 7, packs it in the ceramic container 5, and seals 6 WHEREIN: In order to prevent decay of the heat-processed raw material 7, the average of outside temperature is about -1-3 degreeC. It is desirable to perform it in the cold season, more specifically in the cold season in the calendar. The same applies to the time when the fermentation liquid production process (step S2) and the mixing / molding / drying process (step S3) shown below are performed.
Furthermore, it is desirable that the water 4 is well water or spring water that does not contain chlorine or chlorine. This is because the components contained in the tap water are not preferable for the growth of microorganisms, and are ultimately contained in the spreading material 17b according to the present embodiment and may adversely affect the pigment to be repaired. It is. The same applies to the fermentation liquid production process (step S2) and the mixing / molding / drying process (step S3) described below.
In addition, the protein which comprises a fish body does not recognize a remarkable difference between saltwater fish and freshwater fish. Strictly speaking, it appears that the proteins that make up the migratory fish body are slightly different from the proteins that make up the other fish body. (Refer to “Analysis of fish phylogeny using protein electrophoresis” by Masanari Hayashi and Mai Noda.)
For this reason, the fish 3 used to make the heat-treated raw material 7 in the microorganism species production process (step S1) according to the present embodiment may be a freshwater fish or a saltwater fish. More desirably, it is a fish obtained by removing migratory fish (salmon, tuna, etc.) from freshwater fish or saltwater fish. The migratory fish body contains a large amount of pigment derived from plankton as its feed, and when it is finally contained in the spreading material 17b according to the present embodiment, there is a risk of affecting the restoration target. Because there is.

Next, the process for producing the fermentation broth 15d using the microorganism species 9 will be described in detail with reference to FIG.
FIG. 3 is a flowchart showing a fermentation broth production process according to the embodiment of the present invention. In addition, the same code | symbol is attached | subjected about the same part as what was described in FIG. 1 or FIG. 2, and the description about the structure is abbreviate | omitted.
In the fermented liquor manufacturing process (step S2) according to the present embodiment, as shown in FIG. 3, first, 4 g of water 4; 400 cc is measured per 1 kg of beef glue 12; Then, the glue 12 is swollen with water 4 (step S21).
After this step S21, the swollen beef glue 12 and the remaining water 4 together with the container 11 are simmered in a low heat to make a sol (step S22) to obtain a glue liquid 12b.
Next, 400-500 cc of the microbial species 9 produced in the previous step S1 is added to the glue liquid 12b; 5 kg (= A) and stirred well to obtain a mixed solution 15a (step S23). In addition, the total weight of the mixed liquid 15a obtained here is B in which the microbial species 9 is added to the total weight A of the glue liquid 12b.
Then, the mixed solution 15a (total weight = B) is accommodated in a ceramic container (bottle), and its opening is sealed with a material having a slow air permeability such as Japanese paper or cloth so that direct sunlight is not applied. It is placed on a certain ground surface 8 and naturally fermented for 2 years to obtain a fermented liquid 15b (step S24). The total weight of the fermented liquid 15b obtained here is B ₁ obtained by subtracting the weight of water naturally evaporated from the mixed liquid 15a (total weight = B) and the weight of gas released into the atmosphere as a metabolite of microorganisms. Become.
After this step S23, 150 to 200 g of solid beef glue 12 is added in a dry state to the total weight B ₁ of the fermentation broth 15b to form a mixed solution 15c, that is, a ceramic container that contains the fermentation broth 15b. Is opened, and the beef glue 12; 150-200 g is put in a dry state, and the opening of the ceramic container is sealed with a material having a slow air permeability such as Japanese paper or cloth, and again directly. When it is placed on the ground surface 8 with ventilation that is not exposed to sunlight and naturally fermented for one year, it becomes a fermented liquid 15d (step S25).
Since the fermented liquid 15d is a liquid having a sour odor, it is considered that lactic acid bacteria are proliferating predominantly.
In this case, the total weight of the mixture 15c is a C with weight Ushinikawa 12 to the total amount B ₁ of the fermentation liquor 15b is applied. The total weight of the fermented liquid 15d becomes a weight of moisture natural evaporation from the total weight C of the mixture 15c, and C ₁ minus the weight of the released gas into the atmosphere as a metabolite of the microorganism.

In the fermented liquor manufacturing process (step S2), the beef glue 12 is naturally fermented using the microbial species 9 to produce a microorganism-derived protein that functions as an adhesive component in the fermented liquor 15d. In the process, it has an effect that an enzyme or a metabolite (for example, alcohol or acid) accompanying the activity of microorganisms can be generated.
Further, when the activity of the microorganisms in the fermentation broth 15d decreases, the microorganisms are eventually destroyed by proteolytic enzymes synthesized by themselves or alcohol.
Furthermore, the remnants of microorganisms thus killed (proteins derived from microorganisms) are utilized by other microorganisms to form the body of the microorganisms again.
Then, while the above-described steps are repeated in the fermentation broth, an adhesive component that penetrates smoothly into the repair target is generated and accumulated.
That is, this step S2 is a step of substituting gelatin with an adhesive component that smoothly penetrates into the object to be repaired by the action of microorganisms, and generating proteolytic enzymes and metabolites by microorganisms.
As a result, while increasing the permeability of the spreading material 17b according to the present embodiment into the repair target, and when applying or spraying the solubilized spreading material 17b on the repair target, It is possible to disassemble and remove stains and dirt made of wood crab etc. on the surface to be repaired.

In addition, the beef glue 12 used in the fermented liquor manufacturing process (step S2) was raised without using antibiotics and other chemicals, and at that time, the cow fed feed grown without using agricultural chemicals etc. It is desirable to use as a raw material.
This means that chemicals administered or inoculated to cattle accumulate in the bovine body, and even if meticulous care is taken, they are mixed into the raw material when producing glue.
When such beef glue is used as a nutrient source for propagating microorganisms in the fermentation liquid production process (step S2), chemical substances mixed in beef glue are indirectly taken into the body of the microorganisms. Then, it is mixed in the spreading material 17b according to the present embodiment and finally supplied to the repair target.
Such chemical substances may not only adversely affect the growth of microorganisms in the fermented liquor production process (step S2), but if the pigment constituting the surface decoration to be repaired is a compound or metal, This is undesirable because antibiotics and chemicals derived from pesticides can cause a chemical reaction and damage the original color and aesthetics of the surface decoration.
Further, it is desirable that the beef glue 12 is laid for more than 10 years after being processed into glue.

  Further, the time required for swelling of the glue 12 in step S22 is suitably about 15 hours when the outside air temperature is −1 to 3 ° C. If the soaking time of beef glue 12 is shorter than this, solid content may remain when sol is formed, and if beef glue 12 is soaked for more than 15 hours, decay of beef glue 12 will start. This is because the activity of the microorganism derived from the microorganism species 9 may be reduced in the natural fermentation process (step S24).

Furthermore, in step S23, the case where the heating power is set to low heat and the beef glue 12 swollen by hot water roasting is described as an example, but it is not necessarily performed by hot water roasting, and the temperature is set to 40 to 70 ° C. You may manufacture the glue liquid 12b using the heating equipment which can be set.
In this case, if the temperature is set to 70 ° C. or higher, the protein constituting the gelatin may be denatured and the adhesiveness may be reduced or lost. On the other hand, when the temperature is lower than 40 ° C., solification hardly occurs. Furthermore, even if the temperature is 40 ° C. or higher, if the temperature is low, the sol formation takes time, and the risk that the beef glue 12 will rot increases, which is not desirable.
That is, when the beef glue 12 is made into a sol, it is necessary to work quickly at a temperature as high as possible so that the protein is not denatured.

Further, at a frequency of once a year relative to the fermentation solution 15b prepared in step S2 (total weight = C _1), if you keep the Ushinikawa 12 solid was added 150 to 200 g, more than a year fermentation liquid 15b Even if the fermentation is continued, it can be used without difficulty in the production of the spreading material 17b according to the present embodiment.
That is, by continuously supplying a certain amount of beef glue 12 into the fermentation broth 15d, microorganisms in the fermentation broth 15d are subcultured. By using such a fermentation broth 15b, the spreading material 17b Furthermore, proteolytic enzymes, adhesive proteins derived from the body of microorganisms, and other enzymes and metabolites can be supplied.
If the concentration of the proteolytic enzyme or the metabolite of the microorganism exceeds a certain level, the microorganism itself cannot survive in the fermentation broth 15b. Therefore, it is desirable to use up the fermentation broth 15b before falling into such a state.

Next, the process for producing the solid spreading material 17b using the fermentation solution 15d will be described in detail with reference to FIG.
FIG. 4 is a flowchart showing a mixing / molding / drying process according to the embodiment of the present invention. FIG. 5A is a conceptual diagram showing a state of cutting the solid mixed liquid according to the present embodiment, and FIG. 5B is a conceptual diagram showing the outer shape of the finished product of the spreading material according to the present embodiment. It is. The same parts as those described in FIGS. 1 to 4 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 4, in the mixing / molding / drying step (step S3), first, beef glue 12; 1 kg is immersed in 400 cc of water 4 for about 15 hours to be sufficiently swollen (step S31). A heat treatment is performed for about 2 hours while maintaining the temperature at about 70 ° C. (step S32) to obtain the concentrated glue liquid 12c. The standard of the amount of water evaporated in this step S32 is about 50 to 100 cc.
And 400-500 cc of the fermented liquid 15d is added with respect to the total weight D of the concentrated glue liquid 12c obtained at step S32, and the liquid mixture 17 is obtained.
It should be noted that the addition of the fermentation broth 15d may be performed while heating at a temperature lower than 70 ° C. at which the protein is not denatured so that the concentrated glue liquid 12c does not gel and become uneven when adding the fermentation broth 15d.

Next, the mixed liquid 17 is transferred to a shallow container such as a bat and air-cooled (step S33) to form the solid mixed liquid 17a. Then, the solid mixed liquid 17a is taken out of the container and cut, for example, by cutting off. The solid mixed solution 17a formed into a flat plate shape using a tool is cut into a rod shape as shown in FIG. 5A (step S34), and is exposed to the outside air for about 10 days to be naturally dried. The material 17b is obtained (step S35).
As shown in FIG. 5B, the solid spreading material 17b is a rod-like body whose shape when it is molded is reduced as it is because it does not deform and shrink during drying.
Further, by cutting the solid mixed liquid 17a before drying into a thin rod shape, the surface area of the solid mixed liquid 17a is increased, and it is possible to dry quickly and evenly.

In step S32 described above, the gelatin in the concentrated glue liquid 12c is decomposed by the proteolytic enzyme contained in the fermented liquid 15d by mixing the fermented liquid 15d with the concentrated glue liquid 12c.
As a result, it is possible to prevent deformation and shrinkage when the spreading material 17b according to the present embodiment is dried. In other words, when the restoration work is performed using the spreading material 17b, the spreading material 17b does not cause deformation and shrinkage due to drying, and therefore, it can be used by being applied or sprayed onto the restoration target.

The fermented liquid 15d manufactured in the fermented liquid manufacturing process (step S2) mentioned above contains the protein derived from microorganisms, and the protein derived from microorganisms functions as an adhesive material (spreading material). (See JP-A-48-067481)
Moreover, in the light of ancient art and architectural techniques, proteins derived from such microorganisms are considered to be particularly excellent in terms of durability of adhesion.
For example, when forming earthen walls in Japanese-style buildings, there is a technique in which rice straw is mixed with recycled earthen earth, and the earthen walls are formed using what is fermented and aged while sometimes adding water. However, when this technique is used, it is known that it is superior in strength and durability as compared with a wall formed simply by soil kneaded with water.
Also, when drawing a Japanese painting, after using a device that melts glue, which is a spreading material, the device is stored without washing, and the moldy mold is used as it is for the next drawing. There is also. In this case, it is known that the persistence of the glue spreading effect is higher than that drawn by hygienically managing the glue melting device.

In general, when an object is bonded, an adhesive component enters the uneven portion formed on the surface of the object to be bonded and the object to be bonded, and acts to bond the object to be bonded and the object to be bonded. It is known that
And, the smaller the molecular weight of the adhesive component, the higher the permeability to the adherend and the inside of the adherend, but if the unevenness formed on the surface of the adherend or the adherend is not sufficiently filled with the adhesive component There is no effect.
On the other hand, if the molecular weight of the adhesive component is too large, the adhesive component does not penetrate into the object to be bonded or the object to be bonded, so that the adhesive component cannot function as an adhesive at the bonded part of the object to be bonded or the target to be bonded.
Therefore, in the spreading material of the present invention, microorganisms can be propagated by microorganisms using the gelatin contained in the glue liquid 12b as a nutrient source, and microorganism-derived proteins can be produced in the spreading material. By adding the fermentation liquid 15d to the glue liquid 12c, the action of degrading gelatin-derived gelatin (protein) into a protein having a lower molecular weight can be exerted by the microorganism-derived proteolytic enzyme contained in the concentrated glue liquid 12c. It is estimated that
And it is thought by this effect | action that protein with a small molecular weight osmose | permeates in to-be-adhered object, and acts as an adhesive substance.

Usually, proteins forming the body of microorganisms have a large molecular weight and a complicated structure.
However, when such a microorganism dies, its body is decomposed by its own proteolytic enzyme or alcohol synthesized in the body to become an adhesive component.
And such protein is considered to function as an adhesive by entering and joining the unevenness formed by the fibers of wood and paper and the unevenness formed on the joint surface of the surface decoration.
Thus, since ancient times, humans have skillfully used microorganism-derived proteins as adhesives.

On the other hand, the fermented liquid 15d produced in step S2 contains a large amount of enzymes and microbial metabolites and does not gel even when the temperature is lowered, and thus cannot itself be processed into solid glue.
Further, the moisture content is high, and even if the fermented liquid 15d is used as it is as an adhesive (spreading material), a sufficient adhesive effect cannot be expected.
Therefore, the inventor successfully gelled the fermented liquid 15d containing a large amount of microorganism-derived protein by mixing the fermented liquid 15d into the concentrated glue liquid 12c, and succeeded in processing it into solid glue. did. As a result, the water is sufficiently removed from the protein derived from the microorganism and can be used as an adhesive (spreading material). It can also be easily transported and stored, and can be used whenever necessary.
The protein in the concentrated glue liquid 12c is appropriately decomposed by the proteolytic enzymes and metabolites derived from microorganisms contained in the fermentation liquid 15d, so that the concentrated glue liquid 12c to which the fermentation liquid 15d is added is gelled and dried. No deformation or shrinkage occurs.
Further, when the surface decoration is repaired using the spreading material 17b according to the present embodiment, the protein as the adhesive component is gradually biodegraded over time, and finally from the repair target. It disappears and its bonding effect is lost.
In this case, the surface decoration can be spread again on the support material by repairing the repair target again using the spread material 17b according to the present embodiment.
On the other hand, when the repair target is repaired using an acrylic resin, for example, when the acrylic resin deteriorates and needs to be repaired again, the deteriorated acrylic resin is removed from the repair target. In some cases, it was extremely difficult to repair again.
Compared to this, by using the spreading material 17b according to the present embodiment, it is possible to repeatedly repair, so that the effect of repairing the repair target can be maintained. As a result, it is possible to expect an excellent effect that the cultural property and the art can be stored permanently.
In addition, when repairing using the spreading material 17b according to the present embodiment as described above, since it is necessary to repeat the repairing work every certain period, chemical substances that cannot be biodegraded are present in the spreading material 17b. It is desirable not to be included.

In addition, as shown in FIG. 5 (b), the spreading material 17b according to the present embodiment containing such a protein derived from microorganisms has deformation shrinkage due to drying as compared with the commercially available cow glue 12. Except for not occurring, it is almost the same as the beef glue 12, and the handling at the time of making the sol is the same as the beef glue 12. For this reason, adjustment of the spreading | diffusion material 17b aqueous solution for repair work and preservation | save of the solid spreading | diffusion material 17b are very easy.
The spreading material 17b manufactured in the mixing / molding / drying step (step S3) can be used immediately after manufacturing, but can be used without any problem even when stored for a long period of time.
The spreading material 17b according to the present embodiment is, for example, in which a rice straw is spread on a cardboard box, the dried spreading material 17b is placed thereon, and the rice straw is spread again thereon and stored in a cool and dark place. (Step S36). In this case, it is desirable to replace the rice straw in the cardboard for housing the spreading material 17b with a new one once every two years.
The spread material 17b stored and aged as described above, after about 10 years, is decomposed by a strong odor due to the action of microorganisms adhering to the rice straw and becomes easier to handle.

Furthermore, the spreading material 17b according to the present embodiment is added with a microbial species 9 that is manufactured using all of the ara, fillet, and built-in fish 3 as raw materials in the manufacturing process.
Such microbial species 9 contains a large amount of hygroscopic impurities such as sodium (Na), phosphorus (P), and potassium (K). Such impurities are hygroscopic and have an action of adsorbing and taking in moisture in the air.
Normally, industrially produced beef glue 12 is made by extracting collagen, which is the source of gelatin, from cattle skin and bone and purifying it with high purity. Sodium (Na), phosphorus (P), potassium The content of impurities such as (K) is small.
However, when such an impurity is intentionally included in the spreading material 17b according to the present embodiment and the restoration target is restored using the spreading material 17b, the restoration work is completed after the restoration work is completed. Moisture in the atmosphere can be taken into the repair target at any time by the impurities dispersed in the target.
That is, since moisture is constantly supplied from the atmosphere to the protein that is the spreading material, its viscosity is maintained, and as a result, the adhesive strength of the spreading material 17b according to the present embodiment is suitable in a parallel moisture state. Can be sustained.

In addition, the microorganisms in the fermented liquid 15d are not completely killed even after the mixing, molding, and drying steps according to the present embodiment.
For this reason, microorganisms still exist in the spread material 17b, which is a finished product, and even when the spread material 17b is made into a sol by applying heat in order to use it for repair work, There is no complete death.
This is because the protein forming the microbial body is not completely denatured in a temperature range where the cow glue 12 and the spreading material 17b are solated.
Therefore, when the object to be repaired is repaired using the spreading material 17b according to the present embodiment, microorganisms are supplied to the object to be repaired in a live state.
For example, although it is not visible on the surface of the human body, microorganisms adhere and live together. Such microorganisms act as a barrier, preventing people from being infected by microorganisms that are harmful to humans.
Similarly, by attaching living microorganisms to the object to be repaired in advance, for example, it is possible to suppress the growth of bacteria and microorganisms that contaminate the object to be repaired such as black mold on the object to be repaired. be able to.
In addition, since such a microorganism that protects the object to be repaired can be made alive by using moisture in the air, the protective effect of the object to be repaired can be sustained by the above-described moisture absorption action of the impurities. it can.

Although the detailed mechanism is not known as an effect when the spreading material 17b according to the present embodiment other than the above is used, for example, a gold foil affixed on a wooden support material is raised, It is possible to easily repair an object to be repaired in a state where dust is deposited on the gold leaf. More specifically, the object to be repaired is supported by applying or spraying the spreading material 17b according to the present embodiment, which is solated using water, onto the object to be repaired in which damage as described above is observed. At the same time as re-bonding the gold foil to the material, dust can be removed.
Further, as the effect when the spreading material 17b is used, the detailed mechanism is still unknown, but it was repaired once by the acrylic resin and then repaired as the acrylic resin deteriorated. A thin roll paper is coated on the surface of the object, and a spreading agent aqueous solution in which the spreading material 17b is sol is applied thereon, and further, two sheets of paper having a thickness of about copy paper are stacked thereon. Then, when a light pressing force that rubs with the palm of the hand is applied (see the description using FIG. 6 below), the aqueous solution of the spreading material composed of the spreading material 17b penetrates into the object to be repaired. In addition, the deteriorated acrylic resin present in the object to be repaired can be absorbed by a thin roll paper covering the surface of the object to be repaired.
As described above, according to the spreading material 17b according to the present embodiment, the spreading material 17b is configured so that the working efficiency of the repairing work is improved and the spreading material 17b is biodegradable. It is possible to permanently preserve cultural assets and works of art by performing repair work repeatedly at regular intervals using the.

Here, the repair method of the repair target using the spreading material 17b according to the present embodiment will be described with reference to FIG.
FIGS. 6A and 6B are conceptual diagrams showing a state in which a repair target is repaired using the spreading material according to the present embodiment. The same parts as those described in FIGS. 1 to 5 are denoted by the same reference numerals, and description of the configuration is omitted.
First, prior to the repair work, the spreading material 17b; 5 to 10 g shown in FIG. 5 (b) with respect to 1000 cc of water is made into a sol by the steps S21 and S22 described above, and the spreading solution aqueous solution. 23 is adjusted.
As shown in FIG. 6A, the object to be repaired 24 is in a state in which the surface decoration 19 is raised on the surface of the support material 18.
In the conventional repairing method, the beef glue 12 that has been solated using a syringe or the like is injected into the gap 25 between the support material 18 and the surface decoration 19 one by one and repaired.

When the spreading material 17b according to the present embodiment is used, first, as shown in FIG. 6A, a thin roll paper 20 is formed on the surface of the surface decoration 19 that is in a state of floating on the support material 18. Then, the spreader aqueous solution 23 is applied with a brush or a brush 26, and then two sheets of plain paper 21 having a size of about A4 size are placed on top of each other. The object to be repaired 24 may be rubbed lightly.
At this time, the spreading agent aqueous solution 23 applied on the roll paper 20 quickly penetrates from the roll paper 20 to the inside of the surface decoration 19 and the support material 18, and the surface decoration by the protein in the spreading agent aqueous solution 23. 19 is bonded again to the support 18.
Thereafter, the two plain papers 21 and the roll paper 20 are gently separated from the repair target 24 to complete the repairing work.
In this way, by applying or spraying the spreading agent aqueous solution 23 onto the roll paper 20 coated on the repair target 24, the pigment constituting the surface decoration 19 by the operation of the brush or brush 26 is melted and the color mixture is mixed. It can be prevented from occurring.
According to this method, since the repair work can be performed quickly and reliably even if the range requiring repair is wide, the workability of the repair work can be greatly improved.

As another repair method, for example, when the object to be repaired is a mural or a three-dimensional object, the spreading agent aqueous solution 23 is directly wiped on the surface using a sprayer or the like, or a brush or brush 26 is used. And may be applied directly. Also in this case, the spreading agent aqueous solution 23 can quickly permeate from the surface decoration 19 to the support material 18 thereunder, and the surface decoration 19 and the support material 18 can be re-bonded.
Further, in the case where the surface decoration 19 has been peeled off, the surface decoration that has been spread or sprayed on the support material 18 is applied or sprayed with the spreading material aqueous solution 23 in which the spreading material 17b is adjusted to be thicker. 19 may be pasted.
In addition, the density | concentration of the spreading | diffusion material aqueous solution 23 may be suitably adjusted according to the objective, without being limited to the above-mentioned thing.
Further, the spreading agent aqueous solution 23 has a cloudy amber color, but after being applied to the restoration target 24, the pigment component is not decomposed by the action of microorganisms, so that the original color of the pigment constituting the surface decoration 19 is changed. The risk of damage is extremely low.

Here, the spreading material 17b according to the present embodiment will be described with reference to FIG.
FIG. 7A is a photograph showing the appearance of commercially available beef glue, and both (b) and (c) are photographs showing the appearance of the spreading material according to the present embodiment. The same parts as those described in FIGS. 1 to 5 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 7 (a), commercially available beef glue is sufficiently obtained by gelling gelatin purified and extracted from bovine bones and the like, and forming it into an elongated prismatic shape as shown in FIG. 5 (a). It is dry and has a faint color. The dried beef glue usually marketed is significantly deformed.
As shown in FIG. 7B, the spreading material 17b according to the present embodiment is obtained by drying the long and narrow prismatic solid mixed solution 17a shown in FIG. 5A, but the solid mixed solution 17a. Although the shape is almost the same as that in FIG. 7 and shrinks due to drying, there is no remarkable deformation like the commercial beef glue shown in FIG. Moreover, the spreading | diffusion material 17b shown in FIG.7 (b) is exhibiting the dark blue color.
The spreading material 17b shown in FIG. 7 (c) is obtained by aging the spreading material 17b according to the present embodiment shown in FIG. 7 (b) in a box in which rice straw is laid for more than 10 years. Yes, the drying progressed further than that shown in FIG. 7B, and a transparent brown color is exhibited. Since the drying proceeds further, it is thinner than the spreading material 17b shown in FIG. 7 (b), but significant deformation like the commercial beef glue shown in FIG. 7 (a) is recognized. Absent.

Next, after adding 10 g each of the beef glue (commercially available product) shown in FIGS. 7A to 7C and the spreading material 17b according to the present embodiment to 100 cc of water to swell, it is subjected to a hot water bath. A state in which the sol-formed one is dropped onto an old lacquer coated with lacquer will be described with reference to FIG. In addition, the density | concentration of the aqueous solution used here is the density | concentration of 10-20 times normally the aqueous solution used for restoration of a work of art or a cultural property.
FIG. 8 (a) is a photograph showing the state of the brazing material to which the beef glue (commercial product water) solution is dropped, and (b) and (c) are both dripping the spreading material aqueous solution according to the present embodiment. It is a photograph which shows the state of a firewood. The same parts as those described in FIGS. 1 to 7 are denoted by the same reference numerals, and description of the configuration is omitted.
As shown in FIG. 8 (a), when the beef glue (commercially available) aqueous solution is dropped, it can be visually confirmed that a glossy convex body is formed on the surface of the brazing material. From this, it is thought that the beef glue (commercially available) aqueous solution hardly penetrates into the interior of the straw material.
In addition, when the spreading material aqueous solution 23 obtained by solating the spreading material 17b according to the present embodiment is dropped on the surface of the brazing material, as shown in FIG. Since the appearance of the surface of the material is similar to that of the surrounding brazing material and the gloss is lowered, it is considered that the aqueous spreading material solution 23 in this portion penetrates into the brazing material.
Further, when a spreading material aqueous solution 23 obtained by solating the spreading material 17b accommodated in rice straw and aged for 10 years or more is dropped, as shown in FIG. The surface of the brazing material at the center of the dripping portion has almost the same shape as the surrounding brazing material, and the gloss is greatly reduced. For this reason, it is thought that the spreading | diffusion material aqueous solution 23 has osmose | permeated the inside of a brazing material reliably. In addition, in FIG.8 (c), there was also a location which can hardly confirm the trace which dripped the spreading | diffusion material aqueous solution 23. FIG.
Therefore, the spreading material aqueous solution 23 according to the present embodiment has a higher permeability to the restoration target than the commercially available beef glue aqueous solution, and the spreading material 17b has a longer aging period after production. It can be said that the permeability of the aqueous solution is increased.

  Furthermore, for the purpose of verifying the penetration of the aqueous solution of spreading material 23 according to the present embodiment into the restoration target, the beef glue (commercially available product) shown in FIGS. 7 (a) and 7 (b) and the present embodiment. A 5 wt% aqueous solution or a 10 wt% aqueous solution of the spreading material 17b was prepared, dropped on the surface of a glass plate and a Teflon (registered trademark) plate, and its contact angle was measured with a contact angle meter, as shown in Table 1 below. .

As shown in Table 1 above, when dripping onto each of a glass plate, gold foil, and painted wood (an old one with lacquered lacquer surface), contact with the aqueous spreading material solution 23 according to the present embodiment There was a tendency for the corners to decrease. Moreover, when it dropped on the Teflon (trademark) board which has water repellency, the tendency for the contact angle of a beef glue (commercial item) aqueous solution to become small was recognized.
As a result, it can be said that the spreading material aqueous solution 23 obtained by solting the spreading material 17b according to the present embodiment has higher permeability than the beef glue (commercially available) aqueous solution.

  As explained above, it can be used by directly applying or spraying on the surface decoration of artworks and cultural assets, and it can suitably maintain the adhesiveness in the equilibrium moisture state, and further on the object to be repaired The present invention relates to a spreading material that can remove stains and stains that have been produced, and eventually disappear from the object to be restored after being biodegraded, and its manufacturing method. It can be used in the fields of artistic creation and architecture.
