Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a composite material containing granular material, and belongs to a field in which the granular material itself can be used.

In other words, if a far-infrared ray emitting material is used in the form of powder and granules to make packaging materials, it is possible to maintain the freshness of food, enhance the flavor, and promote ripening, and it can also be used in the medical field, where it activates cells and is excellent for health purposes. can.

In addition, the deodorizing fragrance powder can be widely used as a packaging material for products with good fragrance, and the desiccant powder can be widely used as a 7S removal material.

(Problems to be Solved by the Invention) Conventionally, various powders and granules, such as desiccant materials, have been used in containers or bags, and their uses have been limited.

There are also packaging materials made by kneading powder and granules into synthetic resin and molding them, but because the peripheral surface of the powder and granules are coated with resin, powder and granules can be used as drying materials and fragrances. However, there were drawbacks such as the effect was halved, the transparency as a packaging material became poor, the physical properties changed, and the strength became weaker. Moreover, it may not be possible to knead it into materials due to the nature of powder or granules.

(Means for Solving the Problems) Therefore, the present invention provides a composite body in which powder and granules can be encapsulated in a uniform distribution, and which can be molded by adhering both surfaces at the same time as encapsulation.

For this reason, the present invention uses a film-like or sheet-like plastic material, a plastic film with metal vapor-deposited on one side of various non-woven fabrics, etc. as a composite forming material, and a far-infrared emitting material, a granular material such as a fragrance agent, etc. By applying a large number of spotting parts at predetermined intervals to interpose the composite forming materials on both sides and weld or intertwine and lock the composite forming materials on both sides, both sides are sealed with the powder granules enclosed. It is composed of the following.

(Example) Hereinafter, details of the present invention will be explained with reference to illustrated embodiments.

In the composite material S of this example shown in FIG. 1, powder 3 of a far-infrared emitting material is interposed between plastic films 1 and 2 on both sides as shown in FIG.

Powder 3 is enclosed in a large number of dot-shaped welded parts 4 made by welding powder 3.

That is, as shown in FIG. 3, while the plastic film 1 on one side is running, the powder 3 is sprayed or sieved to adhere to the first side of the film 1, and the plastic film 2 on the other side is applied to the powder-attached side. to join. Next, as shown in FIG.
The film 1.2 is welded using a hot needle K while being passed between the two. At this time, the hot needle is heated to a temperature higher than the melting temperature of the plastic film 1.2, and by inserting it into the film 1.2 and penetrating it as shown in Figure 5, the surrounding film portion melts into the hot needle. The hot needles K are removed from the hot needle rolls 5 which are welded to each other and rotate, and the micro holes E are formed therethrough.

Therefore, since the molten resin penetrates into the powder layer and welds it, the powder 3 is intermittently encapsulated between the welded parts 4, and since the welded parts 4 are partitioned, the powder 3 is extracted from the micropores E. will never appear.

Note that the cooling roll 6 is controlled by a cooling device (not shown) so that the temperature of the rubber layer on the surface does not exceed 100°C, and since the film 1 is not transparent to the heated outer peripheral surface of the hot needle roll 5, the film It will not cause problems through burning or shrinkage deformation.

In this example, the tip diameter of the hot needle is 0.1 mm, the base diameter is 0.5 mm, and the protrusion length is 0.6 mm, so that the diameter of the microhole E formed through the material S is 0.1 mm. 2 mm, and the micropore spacing is approximately 0.6 mm. That is, the number of micropores E to be formed is 1
There are approximately 1 million rrfs, which is extremely innumerable. Therefore, the welded part 4 around the microhole E is about 0.3 mm and has countless spots, which ensures the adhesion of the film 1.2 and also prevents the powder 3 from moving. be.

As described above, according to this example, the composite material S is obtained in which the powder 3 is encapsulated in a uniformly distributed state and in which the micropores E are formed through welding by the hot needle K.

Therefore, since the powder is a far-infrared emitting material powder, it has the following usage effects.

(b) When used for foods as food packaging materials or bedding materials or lining materials in food boxes, it has effects such as improving the freshness of foods, improving flavor, and accelerating the ripening of aged foods. At this time, the bactericidal effect is also good. Fresh flowers also have a longer shelf life.

(o) When used as a temporary material for water, it removes chlorine, calcium chloride, and calcium chloride, making water more delicious. For this reason, the pH becomes alkaline and growth is good, making it suitable for hydroponic cultivation.

(c) It is useful for health by being applied to the human body like a bandage or as an interior material for heating wall materials.

In other words, the conventional effect of far-infrared radiation is utilized as is, and it activates the cells of the human body.

In addition, unlike conventional methods, far-infrared emitting materials are not fired into product shapes, but the powder and granules are used as they are before being molded into the shape they will be used in, making it possible to maintain the far-infrared radiation ratio at its highest level. The effect can be maximized.

Note that the raw materials for the far-infrared ray emitting material and their blending are appropriate, and it is sufficient to ensure a specific wavelength range depending on the application. When targeting a living body, wavelengths of 7 to 12 μm can be completely absorbed and are considered optimal.

(Configuration of the Invention) Although this example is configured as described above, the present invention is not limited to this.

For example, as the composite forming material, in addition to plastic materials, various non-woven fabrics 9 synthetic fibers, natural fibers, plastic films with metal foil attached, etc. can be used in appropriate combinations, as long as they can be spotted on each other. Therefore, composites of similar plastic materials can be easily welded together. In particular, if a plastic film coated with metal foil is used, insulation and heat retention effects can be achieved, and in the case of far-infrared emitting material powder, the far-infrared rays will be reflected on the metal foil surface, resulting in a good irradiation effect.

Further, the composite may be made of forming materials that do not weld to each other, but in this case, any material that can be used as long as the melted material of one of the materials can be intertwined and locked with the structure of the other forming material at the spotting portion is sufficient. for example,
Pulp and polyethylene can easily intertwine and lock together.

Therefore, one side must be made of a soluble material such as a plastic material.Furthermore, regardless of the material of the powder or granules, desiccant,
Any fragrance agent, water-absorbing resin powder, magnetic powder, metal powder such as gold or germanium, etc. may be used depending on the purpose of use, and granules may be used.

Therefore, when used as a packaging material for drying foods, it is effective to encapsulate desiccant powder in a composite material with good air permeability. In addition, it can be made into a composite material made of super absorbent resin powder that absorbs water, and used as a water-retaining material in packaging materials to prevent flowers, seedlings, etc. from drying out, or it can be made into a three-layer material as shown in Figure 7. The present invention can be utilized to form a composite of the following.

Furthermore, the means for forming the dotted portions may be appropriately determined, and may be adhered in the form of a large number of dots by irradiation with a laser beam or the like. In addition, when welding with a hot needle as in this example, it is not necessary to penetrate to the other surface as shown in FIG.

Furthermore, although the size of the spotting parts and the spacing between the spotting parts are appropriate, it is better to make each part smaller and arrange a large number of them.

In short, the present invention uses a film-like or sheet-like plastic material, a plastic film with metal vapor-deposited on one side of various nonwoven fabrics, etc. as a composite forming material, and a far-infrared ray emitting material, a granular material such as a fragrance agent, etc. By providing a large number of dots at predetermined intervals that are interposed between the composite forming materials and welding or intertwining the composite forming materials on both sides and locking them, both surfaces are integrated with the powder encapsulated. It is a composite material encapsulating powder and granules characterized by the following.

(Effects of the Invention) Therefore, according to the present invention, since the powder and granules are encapsulated as they are without any processing, the characteristics of the powder and granules can be fully exhibited and can be used in the legal field. Since the powder particles interposed by the spotting parts are sealed between the spotting parts, movement of the powder particles is prevented regardless of the purpose of use, and the effect of uniformly distributing the powder particles is great.

In addition, because the powder and granules are sealed between the many spots,
This composite material can be cut into appropriate sizes for use.

Furthermore, it has the advantage of being easy to manufacture because the composite forming materials on both sides can be bonded simultaneously by dotting the powder and granular material.
