Description

Far Infrared Radiation Film {FAR INFRARED RAYS RADIATION FILM}

The present invention relates to a far-infrared radiation film, and more particularly, to a far-infrared radiation film to be used as wallpaper, floor covering, clothing, livestock cover and greenhouse mat.

As is well known, far infrared rays have functions (effects) such as uniform heating, promoting the growth of living organisms, activating cells, promoting blood circulation, promoting sweating, and the like. The field of application is used in the form of far infrared radiation sheet or far infrared radiation plate in construction, housing industry, textile, clothing industry, bedding industry, etc. If the far infrared radiation sheet is used for wallpaper, flooring, clothing, etc. By absorbing the far-infrared rays emitted from the sheet, organic compounds (living organisms, living organisms) can exert the effects of promoting growth of living organisms, activation of cells, and the like.

On the other hand, when people adjust themselves to climate change, they wear only clothes that focus on beauty and cover important body parts during the summer, while maintaining body temperature during winter or at night, especially to withstand the outdoors. Although wearing clothes, it is difficult to endure the cold even if activity is inconvenient and wears a lot of clothes. If the temperature is lower than the human body temperature, the verb decreases in body temperature when the outdoor temperature is lower than the human body temperature. Failure to maintain proper body temperature (36.5 ~ 37.0 ℃) slows blood flow and reduces oxygen supply to the brain, causing the brain to become paralyzed, and soon to become paralyzed and die.

Even in the case of livestock, when the body temperature decreases in winter, growth is delayed or the yield of eggs and salt is reduced, so to prevent this, clothes or mats are covered, but activities are inconvenient, Even in the cold season, they may verbally look like people, and also in cultivation of vegetables, especially greenhouses, when the outside temperature decreases during the winter, the growth is slowed or stopped. Instead of lowering the heating temperature in order to reduce the production cost caused by the greenhouse, the greenhouse is usually covered with a thermal mat (quick) made of by-products or waste clothes of a textile factory to maintain the growth conditions of vegetables. It is not blocking.

As described above, if a person wears several layers of clothing or several layers of livestock, the activity is inconvenient, so that a coating layer of polyurethane or the like is formed on the inner surface of the garment (usually referred to as a "wind shield"). Although wearing or coating, the windshield is mainly to the waterproof function by the coating layer of polyurethane or the like, which acts to delay the decrease in body temperature, but the situation where the prevention of the decrease in body temperature is not good.

On the other hand, animals and plants are composed of organic compounds (life forms), which absorb and radiate far infrared rays (e.g., 9 to 10 µm). For example, when humans or animals absorb far infrared rays, the absorbed heat is absorbed in the body. The energy is raised to increase the body temperature, and when the body temperature rises, a mechanism for maintaining the body temperature to be in balance (suitable body temperature) acts to release the sweat to the outside, and when the sweat dries, the heat is taken away from the body by latent heat. It acts to lower body temperature by radiating [FA sensor application encyclopedia; Seonho Park, Oct. 20, 1993, Published by Youngjin Publishers, p. 462.

However, when the far-infrared ray gun of the above-mentioned patent document 1 and patent document 2 or its fabric is used for an organic compound, for example, when clothing is made by a person and worn by a person, the far-infrared ray emitted from a person and / or a second far-infrared source is used for a far-infrared ray gun. When absorbed, only part of it is absorbed and the rest is transmitted to the outside, and only a part of the far infrared rays absorbed by the far infrared ray gun etc. is radiated to a person so that the use efficiency of far infrared rays is lowered because the absorption rate of far infrared rays is small.

The inventor of the present invention has limited the far-infrared radiation sheet correcting the problems of Patent Document 1 and Patent Document 2 described above to Patent Application No. 27471 (hereinafter referred to as "first application 1") in 2009. Wow; A far infrared radiator laminated on one surface of the substrate; Consisting of the reflective layer formed on the far-infrared emitter, the far-infrared radiation emitted from the organic compound is absorbed by the far-infrared radiator, and then the total amount is emitted to the organic compound while preventing transmission to the outside by the reflecting layer, thereby dramatically increasing the absorption rate of far-infrared rays. .

However, the first application 1 has a good far-infrared absorptivity but is composed of three layers, which is complicated in structure, high in manufacturing cost, and has a problem of inferior flexibility due to its thick thickness, and a reflection layer is formed on the far-infrared radiator. Since it absorbs far infrared rays only from one side and the far infrared rays irradiated on the other side is not reflected by the reflecting layer and is not absorbed by the far infrared radiator, it is disadvantageous in terms of efficient use of far infrared rays.

On the other hand, the inventors of the present invention focused on research and development to improve the problems of the above-mentioned first application 1 as a result of forming a single layer, not only simplifying the structure, but also flexible, and can absorb far infrared radiation from both sides in 2009 Patent Application No. 52143 (hereinafter referred to as "first application 2") and 2009 74578 (hereinafter referred to as "first application 3") have been proposed, the first application 2 and the prior application 3 is a synthetic resin by extrusion, floating or knife coater method Far infrared emitters are dispersed in a pellet or a liquid synthetic resin to form a single plate.

However, although the problems of the above-mentioned first application 2 and the first application 3 have been corrected, the problems of the above-mentioned patent documents 1 and 2, namely, the far infrared rays emitted from the organic compound and / or the second far-infrared source are only partially absorbed by the far-infrared radiator. In addition, only a part of the far infrared rays absorbed by the far infrared emitter while the rest is transmitted to the outside is radiated to the organic compound, and thus the problem of small absorption rate of far infrared rays cannot be solved.

An object of the present invention is to provide a single-layer far-infrared radiation film which has all the above-mentioned problems, which simplifies the structure, is flexible, absorbs and radiates far infrared rays from both sides, and increases far-infrared absorptivity.

In order to achieve the above object, the present invention is to form a single layer by dispersing the far-infrared radiator and the metal powder in the synthetic resin film body.

As described above, the far-infrared radiation film of the present invention is formed by forming the film body in a single layer, which simplifies the structure, reduces the cost, and is flexible and easy to handle.

In addition, by dispersing the far-infrared radiator and the metal powder in the film body, when the far-infrared radiation emitted from the organic compound and / or the second far-infrared source is absorbed by the far-infrared radiator, the external transmission is suppressed by the metal powder as a reflector, and the external transmission is suppressed as described above. As the far infrared rays are radiated to the organic compound, the absorption rate of the far infrared rays of the organic compound is increased.

In addition, the metal powder dispersed in the film main body has a good thermal conductivity, so that it is possible to rapidly emit far infrared rays.

The thickness of the far-infrared radiation film of the present invention is determined by design, and typically, the film has a thickness of 0.2 mm or less, and a thickness of 0.2 mm or more is referred to as a sheet, and the term film used below includes a sheet.

  The film body 20 of the far-infrared radiation film 10 may be selected from at least one type of thermosetting thermoplastic resin or rubber. For example, epoxy resin, polyurethane resin, polyvinyl chloride (PVC), polyethylene resin, The far-infrared radiator 30 and the metal powder 40 are mixed with a polyolefin resin such as polypropylene resin, polyvinyl acetate resin, polyester resin, etc., and manufactured by a floating, knife coater or extrusion molding method, and the liquid synthetic resin The one-component or two-component type may be used, and the synthetic resin may be diluted by adding a solvent if necessary.

The mixing ratio of the synthetic resin, the far infrared emitter 30, and the metal powder 40 forming the film main body 20 is preferably 5 to 55% by weight of the far infrared emitter 30 and the metal powder 45 to 95% by weight, In addition, the metal powder 40 is preferably 5 to 35 parts by weight based on 100 parts by weight of the synthetic resin and the far-infrared emitter which is the film body 20. When the metal powder 40 is 5 parts by weight or less, the external permeation of the far infrared rays incident on the film main body 20 is weak, so that the external permeation of far infrared rays is not sufficient to achieve the object of the present invention. By reflecting the far-infrared radiation emitted from the compound and / or the second far-infrared source before the far-infrared radiator 30 absorbs, the achievement of the function of the far-infrared rays is lowered.

The thickness of the film body 20 is preferably about 1 to 30 μm, but the mixing amount of the thickness and the far infrared radiator 30 is determined by design according to the far-infrared radiation amount, the use, and the like. In this case, the thickness is also 0.2 mm or more. You can do it too.

The far-infrared emitter 30 is a zirconia-based far-infrared emitter powder, alumina-based far-infrared emitter powder, silica-based far-infrared emitter powder, and far-infrared radiation is also used as an electromagnetic wave absorber, the electromagnetic wave absorber is carbon black , Conductive loss materials such as graphite, dielectric loss materials such as barium titanate powders, magnetic loss materials such as oxide magnetic materials and metal magnetic powders, and carbon fibers, such as alumina (Al ₂ O ₃ ) or silica (SiO ₂ ) One or more selected from among the electrical loss material powders having a film formed thereon are used, and the far-infrared radiator is one having a wavelength of 5 to 150 µm.

The metal powder 40 is one or more selected from among aluminum, copper, magnesium, tin, and zinc, which has good thermal conductivity and good reflection of far infrared rays, and the metal powder 40 is formed on the film body 20. The external transmission inhibition function of the incident far infrared rays and the heat transfer when the infrared rays radiated from the organic compound and / or the second far infrared source are absorbed by the far infrared radiator 30 dispersed in the film main body 20 and then radiated are good. , The metal powder 40 is to include granules or pieces.

As described above, the far-infrared radiation film 10 of the present invention may be used as a wallpaper, sheetboard, clothing, or the like, or may be combined with a support material (substrate) and installed in an organic compound (object) or in a place of cultivation. When the far infrared rays emitted from the object and or the second far infrared source such as sunlight is irradiated to the film main body 20, the far infrared rays are absorbed by the far infrared radiator 30 on both sides of the film main body 20 and the metal powder By reflecting the egg by 40 and suppressing the external permeation of the far infrared ray, since the absorption amount of the far infrared ray absorbed by the film main body 20 is large, the radiation amount is increased to increase the absorption rate of the far infrared ray absorbed by the organic compound.

As far infrared rays absorbed from the far infrared radiator 30 dispersed in the film main body 20 are radiated to the organic compound while being radiated while conducting to the metal powder having good thermal conductivity, radiation of far infrared rays can be rapidly transmitted because the heat transfer of the far infrared rays is good. Will be.
