Many of the ancient general buildings were plaster walls in which plaster was applied to the surface of a rough wall made mainly of soil. Stucco walls are known to have the effects of fireproofing, humidity control, temperature control, and sound insulation, and typical buildings include storehouses. In modern modern buildings, the foundation is not a soil but a thin wall of artificially manufactured new building material such as gypsum board, and the main surface is a wall structure coated with a wall material containing cement or chemical solvent. Became common. The artificially manufactured new building materials such as gypsum board as the base of the wall do not have breathability, and fire resistance, humidity control, etc.
It has no effect on temperature control and sound insulation. Even in modern times, there are many cases where plaster is applied to the surface of the base of artificially manufactured new building materials such as gypsum board for the purpose of aesthetic formation, but there is almost no breathing effect as when applied to the surface of rough walls, Effects such as humidity control and temperature control are limited to a very small degree. In addition, dew condensation occurs from the wall structure in which a wall material containing cement or a chemical solvent is applied to the base of an artificially manufactured new building material, which causes mold and ticks and allergies, and causes sick house syndrome. It has been confirmed that the following chemical hazardous substances are emitted. In addition, there are many products made of materials made of chemical substances and electric appliances that generate magnetism in the room.In the air inside the room, there are chemical harmful substances such as formaldehyde and toluene, which cause sick house syndrome. It is said to be floating and emit a large amount of electromagnetic waves, which is harmful to the human body.

Therefore, in view of the above problems, the present invention applies a natural material, which does not contain cement or a chemical solvent, but contains burned animal bone powder or the like, to the base surface,
Compared with conventional plaster, it has more effective humidity control, temperature control, heat resistant and heat insulating property, deodorant action, antibacterial action, adsorption of chemical substances such as formaldehyde and toluene, adsorption of electromagnetic waves and magnetic shielding. There is a multifunctional plaster.
It should be noted that this plaster retains strong adsorptivity and strength that will not be peeled off even if it is directly applied to the base, and is further characterized by a shortened process and an aesthetic formation similar to conventional plaster.

SUMMARY OF THE INVENTION The present invention provides plaster containing calcined animal bone meal. The calcined animal bone powder is obtained by boiling raw animal bone, calcining it at around 900 ° C to 1100 ° C, and crushing it. The calcined animal bone meal has the characteristics of main affinity, porous adsorption, ion exchange and swelling, sustaining antibacterial and antifungal effects, temperature control, humidity control, heat retention, anti-condensation, and quick drying. It is known that it has effects of heat absorption, heat dissipation, heat resistance, heat insulation, odor adsorption and deodorization, electromagnetic wave adsorption and demagnetization, and air cleaning action. The present inventor has confirmed that these effects are exhibited when a mixture of the animal bone powder fired in the conventional plaster and applied to a gypsum board or the like on the wall of a house. Therefore, by using stucco containing burned animal bone powder on the walls and roofs of houses, it is possible to absorb the humidity inside the house and keep the humidity at an appropriate level, especially with chemical substances such as formaldehyde and toluene. It has the characteristic of being adsorbed and decomposed and suppressing the onset of sick house syndrome.
It has the characteristic of adsorbing and decomposing various fungi. Further, in the conventional plaster, lime was mixed and solidified, but it was confirmed that the plaster of the present invention solidifies without mixing lime and can be applied as a finish for a house wall or the like. As in the conventional example, egg white and alcohol, in the plaster mixed with beef bone powder, there is a possibility that the mixture will rot because it is an organic matter,
Since the animal bone meal of the present invention is baked, it does not decompose.

It is preferable to blend any one or more of soft porous highly silicified silicate clay (hereinafter abbreviated as silicate clay), diatomaceous earth, and bamboo charcoal in the plaster. It is known that silicate clay has an effect of porous adsorptivity, ion exchange action, etc., and the present inventor tried to include it with animal bone powder obtained by firing silicate clay on stucco, humidity control, etc. It was confirmed that the effect of the above was enhanced, especially the deodorizing and antibacterial effects were enhanced. This is because silicate clay is acidic around pH 6 and the calcined animal bone powder is alkaline around pH 10 so that chemical reactions enhance humidity control, especially deodorizing and antibacterial effects, and also have an ion exchange action. It seems that this effect appears in connection with these. In addition, the calcined animal bone powder is compatible with the silicate clay because it has an affinity for the main constituents.

It was confirmed that when diatomaceous earth or bamboo charcoal was added to the plaster, the same effect as when silicate clay was added was obtained.

kg, preferably 5-10 kg, 20-45 k
g, preferably 21.5 to 43 kg, which is a material commonly used for plaster, such as slaked lime, sizing material, and bamboo grass.
-40 kg, preferably 10-20 kg, is kneaded with water to make plaster, and is applied to a wall surface of a house or the like in an area of 5 to 30 square meters, preferably 7.5 to 15 square meters. The stucco of the present invention may be a stucco in which an appropriate amount of diatomaceous earth or bamboo charcoal is mixed in the above stucco, or may be a stucco in which no silicate white clay is mixed in the above stucco.

As the calcined animal bone powder, one obtained by cutting or crushing animal bone into an appropriate size, boiling and calcining can be used. As the "animal bone" used as a raw material, one or more kinds selected from the group consisting of bones of mammals, fish, birds and other organisms can be used, and herbivorous animals such as cattle, horses and sheep. Mainly composed of bones of
Of these, raw bone that is discarded at livestock farms and the like is preferable. In addition,
Pigs, boars and the like have a lot of cartilage, and most of them may be melted in the boiling process during the production. "Animal bone" as a raw material
Is preferably boiled after being cut or crushed into an appropriate size (for example, 5 mm to 50 mm, preferably 5 mm to 30 mm) to be crushed pieces, particles, or powder. At this time, if the powder is too fine, the melting speed of the aggregate will be slowed by the heat and pressure. The aggregate may be crushed by once freezing the boiled aggregate in a freezer (freezer) or the like and crushing the frozen bone. This is because the bone after boiling has a large amount of water remaining in the pores and is therefore easily frozen, and the frozen bone is easily ground. The freezing temperature at this time is about -100 to -40 degrees, and the time is from 1 to
It is preferably around 3 hours.

Boiling is a process for separating and removing organic substances such as glue, enamel, fat and bone marrow from the bone. By boiling, organic substances attached not only to the outside of the bone but also to the pores are also removed. be able to. Specifically, in the boiling step, the treated bone is put into a pressure cooker (compression cooker) and
Boil for about 60 minutes at about 200 to 400 ° C. while applying a pressure of around atmospheric pressure. At this time, if caustic soda or manufactured bone powder is mixed in the pressure cooker and boiled, the alkalis such as caustic soda and potassium hydroxide cause the organic substances to be saponified and easily dissolved in water, facilitating the separation action of the organic substances. Since it is easily removed from the bone, the boiling time can be shortened. In this case, the amount of caustic soda or bone meal mixed is 2 kg of caustic soda for 200 kg of raw bone.
It is preferable that about 500 g to 1 kg of 100 to 300 cc or bone meal is mixed. The animal bone particles thus obtained are fired at around 900 ° C to 1100 ° C. This makes it possible to sufficiently remove organic substances and the like. After baking, the calcined animal aggregate is preferably pulverized into a powdery bone powder of about 20 to 200 mesh, for example, 50 to 100 mesh by a powder machine, if necessary, and then sufficiently dried. At this time, by treating with caustic soda, organic substances and other stains can be removed more completely.

According to the above-mentioned manufacturing method, for example, when bovine bone is used as a raw material, bone powder having a weight ratio of about 40% of raw raw bone can be obtained, and the bone powder is calcium (about 33%).
(% By weight) as a main component, phosphorus (about 16.7%), barium (about 1.03%), sodium (about 0.76%), sulfur (about 0.64%), magnesium, potassium,
Contains chlorine, amine, iron, etc. In addition, innumerable micropores are continuously present inside and outside the particles, and when ionized, they become alkaline due to calcium, sodium and the like.

Silicate clay is called a high-quality 2-to-1 type montmorillonite clay and is a geological zeolitic clay mineral. In particular, its clay content is white to yellowish white or light brown which has undergone significant silicification. It is a white clay and is mainly produced in Yazawa, Akita Prefecture. Silicate clay is composed mainly of silicon dioxide (about 73% by weight) and aluminum (about 10% by weight).
%), Sodium (about 5% by weight), iron (about 5% by weight), and calcium, potassium, magnesium and the like. The composition unit of silicate clay is colloidal particles (ultrafine particles) in which many cations (metal ions called minerals = minerals) are attached to the core of a negatively charged silicate compound. In addition, silicate clay has a very large content of a displacing base, and therefore has an ion exchange action, and adsorbs and decomposes chemical substances that are considered to cause odor,
It has the characteristic of adsorbing and decomposing various fungi. Silicate clay is around 20 to 500 mesh, for example 350 to 50
It is preferable to pulverize it into a powder of 0 mesh to facilitate mixing.

Hakuo is limestone crushed into sand, and it is preferable to crush it into a powder having a diameter of about 0.5 to 4 mm, for example, a diameter of about 1 mm to facilitate mixing.

Slaked lime is a material that is the main component of plaster, and is a substance that forms the outer wall of a house by drying and slaked lime to be hardened by carbonation by absorption of carbon dioxide in the air.
As the slaked lime, for example, powdered slaked lime, quick lime cream, shell ash and the like are used. Since the stucco of the present invention solidifies without containing slaked lime, it is not necessary to add slaked lime.

The sizing material is a material that gives an appropriate viscosity and measures the bonding and the fixation after drying. As the sizing material, for example, red algae horns, ginkgo biloba, fungus, methylcellulose, etc. are used.

Susas is obtained by cutting fibers such as straw, hemp, and paper into short pieces and loosening them, and has the effect of preventing the material from falling during plaster coating and preventing shrinkage cracks of the coating material after drying.
As the suspiciousness, for example, hamasasa, white-haired rustiness, Nanjing rustiness, exposed rustiness, oil rustiness, paper rustiness, chemical fiber susceptibility, etc. are used.

In addition to the above materials, soybean oil, rapeseed oil, whale oil, etc. for improving water resistance may be blended.

Diatomaceous earth is a light-colored and soft siliceous rock mainly composed of diatom shells, and has a structure having innumerable pores in its particles, and has humidity control, heat resistance, sound insulation, and deodorization. There are features. Bamboo charcoal is mainly made from bamboo, Menso bamboo and the like, and is carbonized by firing in a kettle. It has a porous structure and is effective in controlling humidity and generating negative ions. These are around 20 to 500 mesh, for example 20
It is preferable that the powder is pulverized to a powder form of 0 to 300 mesh to facilitate mixing. The silicate clay, diatomaceous earth, or bamboo charcoal may be blended alone from these, or may be blended in combination.

The preferred mixing ratio of the stucco of the present invention is shown below. Powdered slaked lime, shavings, grass and water are mixed in an appropriate ratio to prepare 10 kg of conventional plaster. 2.5 kg of baked animal bone powder crushed to 300 mesh, 2
Silicate white clay (manufactured by Soft Silica Co., Ltd.) crushed to 00 mesh 5 kg, Hakuo crushed to a diameter of around 1 mm (manufactured by Hitachi Inada Crushed Stone Sales Joint Stock Company, Chichibu, Saitama) 21, 5k
g and well mixed to obtain the plaster of the present invention. The above plaster is applied to a wall surface of a house by a general construction method, and the above weight is applied per about 7.5 square meters.

As another mixing ratio, conventional stucco 20 kg, baked animal bone powder 5 k crushed to 300 mesh
The same effect can be obtained by mixing 10 kg of silicate white clay pulverized to 200 g with 200 g and 43 kg of Shiraoh pulverized to a diameter of about 1 mm and applying the mixture per about 15 square meters. When only the calcined animal bone powder is contained in the plaster, it is preferable to mix 20 kg of the conventional plaster and 43 kg of Hakuo with 15 kg of the calcined animal bone powder, and apply the mixture per about 15 square meters. The mixing ratios are not limited to the above-mentioned ones, and these are those enumerated for which suitable results were obtained in the experiments conducted by the present inventor. In addition to the above, as the mixing procedure, the stucco of the present invention may be prepared by stirring all the materials and then adding water, or dissolving the fusuri with water and then adding the remaining materials.

Stucco containing fired animal bone powder or stucco containing fired animal bone powder and silicate clay was applied to a plasterboard on the wall of a room of 6 tatami mats. It contains silicate clay, which has a porous adsorptivity, and has a high swelling property for adsorbing water to these, so that the indoor humidity is kept suitable. In addition, chemical substances such as formaldehyde and toluene, which are considered to be the cause of sick house syndrome, are also adsorbed and decomposed, and these concentrations can be reduced over time, and the components that cause air purification and odor are also adsorbed and decomposed, It was confirmed that the indoor can be deodorized. Baked animal bone powder is alkaline, so it can sterilize mold spores, various fungi, etc. to suppress reproduction, and also has the function of adsorbing and shielding from electromagnetic waves, thus damaging indoor electromagnetic waves to the human body. Since it can be weakened and blocked so that it does not exist, and it easily solidifies, it retains the strength of the surface even when applied thinner than conventional plaster and does not peel off.

As a result of comparing the case where only the burned animal bone powder was mixed with the plaster and the case where the burned animal bone powder and the silicate clay were mixed, the case where the burned animal bone powder and the silicate clay were mixed was deodorized, The present inventor has confirmed that sterilization of various fungi and the like shows a great effect. These are silicate clays with an acidity of around pH 6 and baked animal bone powder with a pH of 1.
It is considered that the chemical reaction occurs because it shows an alkalinity of around 0, the components that cause the odor are decomposed, and various fungi and the like are sterilized. In addition, since silicate clay has an ion exchange action and contains montmorillonite clay that adsorbs and decomposes toxic gases, it also has an action of adsorbing and decomposing chemical substances that cause odor and adsorbing and decomposing various miscellaneous bacteria. It seems that the synergistic effect shows a great effect.

The stucco of the present invention may further contain diatomaceous earth or bamboo charcoal. Since the diatomaceous earth or bamboo charcoal has innumerable pores and has a porous structure, by blending with calcinated animal bone powder, Similar to the above, it exerts a great effect on humidity control and the like.

The calcined animal bone meal becomes more reactive as the temperature rises, and the above-mentioned effect becomes stronger. Therefore, the plaster of the present invention is particularly suitable for the summer and heating.
