DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a granular material having a far-infrared radiation function and a method for producing the same.

[0002]

2. Description of the Related Art In recent years, it has become widely known that far-infrared rays contribute to the promotion of human health, and various products such as health appliances and clothing having a function of irradiating far-infrared rays to the human body have been developed and marketed. Have been.

[0003] In addition, when a building is constructed by mixing a material emitting far-infrared rays as an aggregate with construction materials such as concrete, the effect of suppressing moisture and dew condensation and absorbing toxic gas after construction is obtained. It is also known that

Further, it has been found that mixing a far-infrared radiating substance into soil for plant cultivation has effects such as promoting the growth of plants and maintaining the freshness of plants for a long period of time. I have.

As far-infrared radiating substances which have been widely used in such products utilizing the excellent functions of far-infrared rays, there are natural minerals such as tourmaline and powders of ceramics.

[0006]

[0006] Tourmaline used as a far-infrared radiating substance is a relatively rare natural mineral, and its composition is not constant, so that it cannot be stably supplied in large quantities. Tourmaline exhibits a far-infrared radiation function when used as a fine powder, but does not generate sufficient far-infrared rays unless rubbed or heated. Further, when the temperature becomes high, its delicate composition changes or decomposes, so that it is difficult to maintain the quality, and it cannot be used for products fired at a high temperature such as porcelain.

On the other hand, conventional far-infrared radiation ceramics have insufficient far-infrared radiation function at room temperature.
Heating is required. In addition, since many particles have a relatively large particle size, usable objects are limited.

An object of the present invention is to provide a far-infrared radiating granule having an excellent far-infrared radiating function, excellent stability, and usable in various industrial fields, and a method for producing the same. .

[0009]

The far-infrared radiating granules of the present invention are granules obtained by coating the surface of a granule with a natural or synthetic resin containing a far-infrared radiating substance.

[0010] With this configuration, far-infrared rays are emitted from the far-infrared ray emitting material-containing layer coated on the surface of the granular material. Exhibits radiation function. In addition, the far-infrared radiation material is contained in the natural resin layer or the synthetic resin layer, so it has excellent stability, and the far-infrared radiation particles themselves are literally granular, so they are easy to handle and can be used in various industrial fields. It is.

The natural resin or the synthetic resin constituting the coating layer may be any one which is water-soluble and transmits far infrared rays.
The natural resin can be used without any particular limitation as long as it is made of plant sap. The synthetic resin is preferably an acrylic resin, a polypropylene resin, a polycarbonate resin or a vinyl chloride resin.

As the far-infrared radiating substance, a substance containing a fossil powder of animal and phytoplankton can be used. The use of powders containing these powders can emit far-infrared rays with high efficiency, which is effective for promoting human and animal health and promoting plant growth. It generates far-infrared rays efficiently without adding any external action.

As a fossil of animal and phytoplankton, about 1
It is desirable to be a place that was a continental shelf under the sea with a depth of about 200 m a million years ago and that is now a land area. The present inventors have confirmed through research and experiments that such animal and plant plankton fossils have a function of emitting far-infrared rays with high efficiency.

The particle size of the powder of the far-infrared radiating substance is 0.1.
By processing to such a particle size, uniform dispersibility of a natural resin or a synthetic resin in an aqueous solution can be ensured, and fusion with water molecules in this aqueous solution can be ensured. It is presumed that there is also an effect of progressing and forming a crystal that emits far infrared rays of a specific wavelength by itself.

Further, the natural resin or the synthetic resin coating layer contains a mineral substance contained in seawater together with a far-infrared ray radiating substance to stabilize the wavelength of far-infrared ray or selectively remove far-infrared ray of a specific wavelength. , Which can generate far-infrared rays having a composition similar to that of seawater and easily absorbed by the human body, and far-infrared rays having a wavelength effective for the human body. Note that the mineral substances contained in seawater refer to magnesium, potassium, titanium oxide, calcium, sodium, and the like.

Specifically, when a mineral substance of the same kind as that contained in the human body is contained, far-infrared rays having a wavelength effective for blood, body fluid, and cell fluid constituting the human body are generated, and the vitality of the human body is increased. It has the function of activating, and when it contains the same kind of minerals as the minerals contained in the plant, it exerts the function of generating far-infrared rays with a wavelength effective for the cell body of the plant,
Plant growth can be promoted, the yield can be increased, and the quality of the harvest can be improved. In addition, if minerals of the same type as those contained in high-quality soil are contained, they will act on harmful chemical substances contained in the soil to remove harmfulness and activate the soil by giving so-called ground strength. Can be.

As the granular material constituting the far infrared radiation granular material, any of sand, gravel, wood particles, glass particles, resin particles, and metal particles can be used. Since sand and gravel are natural materials, they are relatively easy to obtain, the particle size can be easily selected according to the application, and the coating properties and adhesion of natural resins and synthetic resins are good. Since the specific gravity of the wood particles and the resin particles is small, it is possible to reduce the weight of the far-infrared radiating granular material, and it is possible to secure the durability and heat resistance by using glass particles and metal particles. In addition, since wood particles, glass particles, and metal particles can be formed using wood, glass, and metal waste materials as raw materials, the reuse of resources can be promoted by using waste materials. The particle size of the granular material using these as a material is not particularly limited, but in consideration of versatility, handleability, and the like, about 0.1 to 15 mm, preferably 0.2 to 15 mm.
About 5 mm is preferable.

The above-mentioned far-infrared radiation particles can be obtained by immersing the particles in a liquid in which a powder of a far-infrared radiation substance is dispersed in an aqueous solution of a natural resin or a synthetic resin, or by spraying the liquid onto the particles. Then, by drying the granular material to which the liquid material has adhered, a granular material having a coating layer in which the far-infrared radiating substance is uniformly dispersed on the surface of the granular material can be manufactured.

In the above-mentioned production method, the temperature of the aqueous solution is desirably 40 to 50 ° C. in order to uniformly disperse the powder of the far-infrared radiating substance in the aqueous solution of a natural resin or a synthetic resin. By uniformly dispersing the powder of the far-infrared emitting material in the aqueous solution, the powder of the far-infrared emitting material is uniformly dispersed in the coating layer on the surface of the granular material.

Here, the composition ratio of the liquid material is defined as water 85
~ 95% by weight, natural or synthetic resin 2.5 ~ 7.5
By weight, the far-infrared radiating substance of 2.5 to 7.5% by weight facilitates dissolution of the resin, uniform dispersion of the far-infrared radiating substance, and coating, and has excellent far-infrared radiating function and durability. Far-infrared radiating granules having an excellent coating layer can be obtained.

Further, by adding a mineral substance contained in seawater to the liquid material, a far-infrared ray having a certain wavelength or a far-infrared ray having a specific wavelength is selectively emitted as described above. In addition to being able to form far-infrared radiation particulates, it is possible to generate far-infrared rays that are effective for the human body.

In the case where it is necessary to color according to the use of the far-infrared radiation granular material, a colored coating layer can be formed by mixing a colorant of a specific color into the liquid material.

The far-infrared radiation particles are mixed with concrete or the like as an aggregate of a building material, and are mixed with the outer and inner walls of the building.
In addition to building floors and walls in the bathroom, it can be sprayed directly below the floor, or directly coated on the roof, exterior walls, and surfaces of interior materials. Also, it can be sprayed as a ground for a lawn such as a golf course or a soccer field.
In any case, antioxidation, elimination of active oxygen,
It exerts effects such as controlling moisture and dew condensation, absorbing toxic gas, keeping warm, deodorizing, and antibacterial. When used as a base for a lawn, if the coating layer of the far-infrared radiating granular material is colored green, the fading and browning of the lawn in winter and the like can be compensated.

The far-infrared radiation particles can be mixed with sand in pet toilets, scattered in aquariums for ornamental fish such as goldfish, or mixed with soil in flowerpots to deodorize. Antibacterial and growth promoting effects are obtained. Also in this case, if the far-infrared radiation particles are colored, the appearance is improved and the decorative function is also exhibited. In addition, by mixing it in cultivation soil for cultivation of flowers and vegetables in the agricultural field, or by throwing it into fish farms and water tanks in the fisheries field,

A synthetic resin coating layer 13 containing a far-infrared radiating substance 12 is formed on the surface of the substrate.

By taking such a step, the far-infrared radiating granular material 10 having the synthetic resin coating layer 13 in which the far-infrared radiating substance 12 is uniformly dispersed is formed on the surface of the granular material 11.

Next, another manufacturing method of the far-infrared radiating granular material 10 will be described with reference to FIG. First, FIG.
As shown in FIG. 2, a liquid 17 is prepared in the same manner as in FIG. Thereafter, as shown in FIG. 3B, the liquid material 17 is sprayed on the granular material 11 stored in the gas permeable container 21 by using a spray gun 19 in which the liquid material 17 is put in a tank 20. The liquid 17 is attached to the surface of the granular material 11. Then, as shown in FIG. 3C, when the hot air 18 is blown and dried, the far-infrared radiation granular material 10 is formed.

In the case of the present embodiment, since the liquid 17 is attached to the surface of the granular material 11 by spraying the liquid 17, the granular 11 is immersed in the liquid 17 for a long time.
The manufacturing time can be reduced as compared with the manufacturing method of (1).
