Description

  The present invention relates to a coating powder that generates negative ions, applied to interior wall materials, ceiling materials, and the like, and more specifically, scallop shells are pulverized and fired to have a particle size of 10 μm to 50 μm. Powdered scallop shell powder is used as a binder, and the binder is mixed with 3% to 10% by weight of negative ion powder having a particle size of 0.1 μm to 50 μm mainly composed of ore that generates negative ions. It is related with the powder for negative ion coating characterized by the above-mentioned.

  Conventionally, many paints for interiors mainly composed of scallop shells have been developed. In Japan, scallops are cultivated mainly in the Tohoku and Hokkaido regions, and the amount of scallop shells to be discarded is an enormous amount every year, which has become a social problem as industrial waste. Therefore, one of the methods of effective use of this scallop shell is drawing attention as a coating powder applied to interior wall materials and ceiling materials. Listed in Patent Documents 1 and 2 below.

Most of the scallop shells are made of calcium carbonate, and have been confirmed to have the following functions by pulverizing and firing at high temperature to form a fine powder of calcium oxide (the following non-patents) It is described in detail on page 6 and below of Reference 1.)
Antibacterial and antibacterial functions: Chemical substance mitigation function against Staphylococcus aureus, Escherichia coli, etc. Formaldehyde and VOC (volatile organic compounds) Odor function etc. These effects are all important for improving the environment of the house. However, in recent years, the so-called “sick house syndrome” (general health damage caused by houses) has become a problem. The effect of reducing chemical substances contained in building materials, adhesives, paints, etc., which are considered to be one of the causes, has been attracting attention, and interior paints mainly composed of scallop shell powder having the above functions have come into the spotlight ( Non-Patent Document 1 on page 13 below and Non-Patent Document 2 below).

On the other hand, the positive effect of negative ions on the human body has gradually become apparent through various clinical cases in recent years. These effects are described in detail in many non-patent documents 3 on page 265 and below, with many clinical examples. The main ones are as follows.

  There are fine particles that are positively or negatively charged in the air. Among these, positively charged particles are called positive ions, and negatively charged particles are called negative ions (the following non-patents). (Refer to page 100 of reference 3). Negative ions include “small ions” with about 10 to 30 molecules, “large ions” whose mass is about 1000 times that of small ions, and “medium ions” between them. Currently, negative ions that are said to give good results to the human body are “small ions”, and if the air is polluted near the city due to the influence of smoke, the proportion of large ions will increase. ing. Therefore, in the following description, when “negative ion” is simply described, it means this “small ion”.

  Therefore, to create an environment that gives good results to the human body, the number of small ions in the air should be increased. There are various methods to increase the number of small ions in the air, such as a method of discharging high voltage in the air, a method of using ultraviolet light, and a method of breaking water finely, but it is always stable without using power. As a method for generating small ions, there is a method using a negative ion generating material. This method is the simplest and has a wide range of applications, and is currently used in various fields. Various paints containing these negative ion generating substances have been developed. Some of them are listed as Patent Documents 3 to 6 below.

  Various substances are now known as negative ion generating substances, but monazite (monazite) and tourmaline are often used. However, monazite has a high content of thorium oxide and is a radioactive substance that emits γ-rays of 800 becquerel (Bq / g) or more, which is 370 of the standard value of γ-rays that is considered to be safe. Becquerel (Bq / g) is far exceeded. Therefore, monazite is considered to be a radioactive material that needs to be notified to the Nuclear Safety Division of the Ministry of Education, Culture, Sports, Science and Technology in advance. Careful consideration is required for handling and processing, and it cannot be used simply. . On the other hand, tourmaline is used in many fields because its radiation dose is below the standard value and can be used safely, and it seems that it is now synonymous with a negative ion generator. However, the disadvantage of tourmaline is that the amount of negative ions generated is very small in the natural state, and therefore various effects on the human body due to negative ions remain very weak. This point is as described in detail in the prior art section of Patent Document 5 below.

  In contrast, the rare ion ore # 515, a negative ion generating substance, generates a much larger amount of negative ions than tourmaline in the natural state, but the radiation amount of γ rays is 370 becquerels (Bq / g), which is the reference value. ) It is a powerful negative ion generator that can be used safely without requiring prior notification to the Nuclear Safety Division of the Ministry of Education, Culture, Sports, Science and Technology. However, it has been difficult to pulverize this substance into a fine powder that can be mixed with other substances and has not been used so far. The rare earth ore # 515 is a powdered material in which various rare earth elements are mixed mainly with cerium, lanthanum, neodymium, and promesium (also referred to as promethium).

As mentioned above, both scallop shell powder and anion-generating substances are substances that can have a good effect on the human body, but there are no materials containing both of them, especially in the field of architectural interior paints. The following patent documents 7 and 8 correspond to those containing both scallop shell powder and a negative ion generating substance. Patent document 7 is an antibacterial agent and antibacterial sand, and patent document 8 is a ceramic for sterilization.

As mentioned above, there is no interior paint containing both scallop shell powder and a negative ion generating substance, and it is not an interior paint that contains both. Agent and antibacterial sand and ceramics for sterilization of Patent Document 8 mentioned above. Therefore, it is conceivable to apply these to interior paints, but the antibacterial agent and antibacterial sand of Patent Document 7 have a problem in that weakly effective tourmaline is used as a negative ion generating substance. Further, the negative ion generating substance used in the ceramic for sterilization of Patent Document 8 is zeolite, but this substance has a long-lasting antibacterial action and is toxic when ingested by a pet or an infant. There is a danger of showing.

As mentioned above, scallop shell powder has sterilization and antibacterial functions, chemical substance mitigation functions,
It has chemical substance decomposing function, insect repellent and deodorizing function, and it must be said that it has ideal properties as an interior paint. On the other hand, negative ions also have various effects on the human body as described above, and the interior paint can contain a substance that generates negative ions sufficiently and continuously. These effects can be expected. Negative ions are also said to have an effect of preventing the above-mentioned functions of scallop shell powder from being attenuated. Accordingly, an object of the present invention is to develop a safe and easy-to-use interior paint that can combine the above functions of scallop shell powder and the above functions of negative ions.

The present invention has been made to solve the above problems, and provides the following means for solving the problems.

Carbon or carbon dioxide is adsorbed on the scallop shell powder and prevents the scallop shell powder from being oxidized. , Chemical reduction function, the chemical decomposition function, other, insect repellent, can be long-lasting the effects in all of the deodorizing function.

The negative ion coating powder of the present invention comprises scallop shell powder pulverized by scallop shell and fired into a powder form having a particle size of 10 μm to 50 μm as a binder, and an ore that generates negative ions in the binder as a main component. Since the negative ion powder having a particle size of 0.1 μm to 50 μm is mixed with 3% to 10% by weight of the whole, the negative ions are always sufficiently generated at room temperature, and the negative ions give the human body.

It also has the effect of reducing carbon dioxide and the like.
Effect of always generating negative ions: Since negative ions are generated by a negative ion generating substance (rare earth ore # 515 and tourmaline) without using power, negative ions can be generated constantly at room temperature. Therefore, the various effects of negative ions can be exhibited at all times. It is also effective in removing positive ions harmful to the human body.

Fireproofing effect: Since scallop shell powder and negative ion powder are both inorganic, they have a fireproofing effect. The examples of the present invention have passed a fire performance test.

  The negative ion coating powder of the present invention is mainly composed of rare earth ore # 515 that generates a large amount of negative ions in the negative ion powder, which is a component that generates negative ions. For example, it can be much higher than when tourmaline or the like is used as a main component, and the above-mentioned various effects due to negative ions can be made more prominent.

  The negative ion coating powder of the present invention is the above-mentioned negative ion powder, which is a component that generates negative ions. ) Since the following rare earth ore # 515 is the main component, safety is high, and rare earth ore # 515 is not a radioactive material that requires notification to the Ministry of Education, Culture, Sports, Science and Technology's Nuclear Safety Division in advance, like monazite Therefore, handling is very simple.

Since the powder for negative ion coating of the present invention contains a powder of wax, the overall texture can be made fine, and the whiteness necessary as a paint to be applied to the wall surface material can be increased. It is.

The negative ion coating powder of the present invention uses rare earth ore # 515 having a large negative ion generation amount as a main component, and tourmaline having a low negative ion generation amount as an auxiliary component. . For this reason, it is possible to easily control the amount of negative ions generated by changing the component ratio between the two.

  The best mode for carrying out the invention will be described in detail below with reference to the drawings.

Next, the present invention will be described in detail based on the following embodiments. First, the process of manufacturing the scallop shell powder used as a binder is as showing to process S1-process S3 of FIG. In step S1, scallop shells are crushed and fired in step S2. Thereby, the scallop shell powder mainly composed of calcium, which is partly calcium oxide, can be obtained (step S3). The particle diameter of the scallop shell powder is between 10 μm and 50 μm. The reason for this numerical limitation is that if the particle size is less than 10 μm, the processing effort during pulverization becomes too large to be practical, and if the particle size exceeds 50 μm, the particle size becomes too large to serve as a binder. Moreover, it is because a bad effect comes out to use as a paint.
When used as a spray paint, the particle size of scallop shell powder is made as fine as possible.

  Next, the production process of the negative ion powder is as shown in steps S4 to S8 in FIG. First, in step S4, tourmaline is pulverized to a particle size of 6 μm to 50 μm. The reason for this numerical limitation is that if the particle size is less than 6 μm, the processing effort at the time of grinding becomes too large to be practical, and if the particle size exceeds 50 μm, the particle size becomes too large to lose the smoothness of the paint. by. In step S5, the wax is pulverized to a particle size of 6 μm to 50 μm. The reason for this numerical limitation is also the same as the reason for limiting the numerical value of the particle size of tourmaline. Furthermore, in step S6, the rare earth ore # 515 is pulverized to a particle size of 0.1 μm to 6 μm. Since the rare earth ore # 515 becomes easier to mix with other components as the particle size becomes finer, the maximum particle size is limited to 6 μm. The rare earth ore # 515 can be pulverized in a normal mill (not shown) up to a particle size of 1.0 μm (sintering and pulverizing the material pulverized by the mill). In order to obtain a particle size of less than 1.0 μm, it is pulverized in a liquid by a mill (not shown).

When tourmaline, wax, and rare earth ore # 515 powder are obtained in this way, the three are mixed (step S7) to obtain negative ion powder (step S8). The mixing ratio is 50% to 80% by weight for rare earth ore # 515 powder, 20% to 40% by weight for tourmaline powder, and 15% to 30% by weight for wax stone powder. The reason for limiting the numerical value of rare earth ore # 515 powder is that when rare earth ore # 515 powder is less than 50% by weight, a sufficient amount of negative ions cannot be obtained, and when it exceeds 80% by weight, negative ions are generated. This is because the amount becomes too large. That is, the amount of negative ions generated in the whole negative ion powder is adjusted mainly by adjusting the ratio of rare earth ore # 515 powder. In contrast, tourmaline powder plays a role in finely adjusting the amount of negative ions generated, and when the amount of rare earth ore # 515 powder is increased, the lower limit of the amount of tourmaline powder is 20% by weight, and rare earth ore # 515 powder is small. This means that the upper limit of the amount of tourmaline powder is 40% by weight. The reason for limiting the numerical value of the wax stone powder is that if the wax stone powder is less than 15% by weight, the smoothness of the whole negative ion powder is lost, and the white feeling when mixed with the scallop shell powder as a binder is lost. This is because if the rholite powder exceeds 30% by weight, the amount of rare earth ore # 515 powder and tourmaline powder is relatively reduced, which affects the amount of negative ions generated. The particle size of the negative ion powder is 0.1 μm to 50 μm according to the above description, but the average particle size is 50% by weight of rare earth ore # 515 powder, 20% by weight of tourmaline powder, and rouxite powder. When it was 30% by weight, it was 2.62 μm. Table 1 and Fig. 2 show the results of the analysis of granular materials in Aichi Ceramic Industry Cooperative. When the graph of FIG. 2 is seen, the particle size of the negative ion powder of this sample is concentrated between 1.0 μm and 10 μm. An easy-to-use negative ion powder can be obtained.

Next, the scallop shell powder obtained in the step S3 and the negative ion powder obtained in the step S8 are mixed (step S9) to obtain a negative ion coating powder as a final product (step S10). The mixing ratio at this time is 90% to 97% by weight of scallop shell powder as a binder and 3% to 10% by weight of negative ion powder. The reason for this numerical limitation is that when the amount of negative ion powder is less than 3% by weight, the amount of negative ions generated becomes too small, and the effect of mixing the wax is not obtained so much. On the other hand, when the amount exceeds% by weight, the amount of negative ions generated becomes too large, and the effect of the scallop shell powder as a binder is diminished. In particular, the lower limit of 3% by weight of the negative ion powder has an important meaning, and the final product obtained at this ratio is dissolved in water and applied to the wall at a normal thickness. The number of negative ions per 1 cm ^{3 of} air is about 300, which is 20 to 30 times the number of negative ions per 1 cm ³ of air in a normal house. This is because it is regarded as a kind of reference amount for obtaining prominently. In addition, the ratio of the scallop shell powder as the binder is naturally 100% by weight minus the ratio of the negative ion powder. In addition, it is natural that a pigment or a coagulant can be appropriately mixed. In this case, the amount of scallop shell powder as a binder is reduced by the amount of the pigment or the coagulant. In this case, since the scallop shell powder of the binder is a natural material, it is desirable to use a natural material for the pigment and the coagulant.

  The negative ion coating powder of the present invention can be widely used not only for ordinary indoor interior coatings but also for indoor coatings of hospitals, schools, factories, public facilities, and other buildings. The function of the scallop shell powder and the various effects of negative ions can be given to a person. Furthermore, it is also effective when used as a paint for inner surface coatings related to equipment of buildings and facilities such as intake ducts and exhaust ducts, and can also be printed on clothing and wallpaper as a paint for printing. Furthermore, if it is used as an inner surface coating agent for water treatment equipment such as various water purifiers, it has an outstanding effect on water purification, and can also be used as a spray paint (coating agent).

It is process drawing of the Example of this invention. It is a reference figure showing the measurement result of the granular material of the negative ion powder of the Example of this invention.
