Ultraviolet rays refer to electromagnetic waves of 400 nm or less. Particularly, ultraviolet rays of 290 nm or less are absorbed and removed by the ozone layer and hardly reach the surface of the earth. However, as the destruction of the ozone layer has recently accelerated, the amount of ultraviolet rays harmful to living organisms reaching the surface of the earth is increasing. When the skin is exposed to ultraviolet rays, it causes skin blackening or erythema.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention of the user, the operator, or the precedent. Therefore, the definition should be based on the contents throughout this specification.

FIG. 1 is a block diagram illustrating a process of fabricating a nano-copper composite, fiber, and fiber fabric having an infrared absorption and thermal storage function according to the present invention.

Referring to FIG. 1, a method for manufacturing a nanocarpal-based composite having infrared absorbing and storing functions according to the present invention includes steps S1 through S6 of preparing a copper-based composite containing CuS as a main component and CoS and Ag ₂ S at a predetermined weight ratio And 5 to 20 parts by weight of the copper-based composite, 1 to 5 parts by weight of a dispersant, and 75 to 84 parts by weight of an organic solvent to prepare a primary dispersion; and a step of adding an additive to the primary dispersion to prepare 2 A step S3 of preparing a tea dispersion, and a step S4 of drying the secondary dispersion.

More specifically, step S1 of the present invention is a method of obtaining a precipitate containing CuS, CoS and Ag ₂ S by mixing a first metal salt solution containing CuSO ₄ , Co (NO ₃ ) ₂ and AgNO ₃ with a Na ₂ S solution And a step S1-2 of drying and pulverizing the precipitate and then sintering at 250 to 350 DEG C to prepare a copper-based composite.

In addition, the step S1-1 is a CuSO ₄ solution, Co (NO _{3) 2} solution, which provided the AgNO ₃ solution was respectively mixed with a solution of Na ₂ S, and then, precipitates CuS, CoS precipitate, the predetermined weight ratio Ag ₂ S precipitate These precipitates may be mixed in a predetermined weight ratio in the step S1-2, followed by drying and pulverization.

CuS, which is a main component of the copper-based composite, absorbs and stores near-infrared rays, and CoS serves to reinforce absorption of light in the near-infrared region. The Ag ₂ S imparts an antimicrobial function along with far- .

The Cu-based composite in step S1 is preferably composed of 90 to 98 parts by weight of CuS, 2 to 3 parts by weight of CoS, and 0.1 to 1 part by weight of Ag2S.

If the CoS is less than 2 parts by weight, it is difficult to expect the light absorption performance of the above-mentioned near infrared region to be reinforced, and even if it exceeds 3 parts by weight, the increase of the absorption rate of light in the near- . When the amount of Ag ₂ S is less than 0.1 parts by weight, antimicrobial function is not expected to be expected. When the amount of Ag ₂ S is more than 1 part by weight, the rate of increase of the antimicrobial function is lower than that of the manufacturing cost.

Also, it has been experimentally confirmed that the composition ratio of the copper-based composite material includes CuS alone or CuS or Ag ₂ S is omitted in the copper-based composite or nanoporous-based composite, or the heat storage performance is significantly lowered when the weight ratio is exceeded .

Meanwhile, in step S1-2, the precipitate is pulverized and then sintered. The sintering process is preferably performed in a non-reactive atmosphere in which nitrogen is flowed in order to minimize the rate at which the precipitates are not oxidized or oxidized. This is because, when sintering is performed in an atmosphere in which oxygen is supplied, precipitates, specifically CuS, are rapidly oxidized.

The temperature for sintering the precipitate in step S1-2 is preferably 250 to 350 ° C.

If the sintering temperature is lower than 250 ° C., crystallization of the precipitate due to sintering is not smoothly performed, resulting in deterioration of far-infrared ray absorption and storage performance. If the sintering temperature exceeds 350 ° C., the reactivity becomes large. And the far infrared ray absorption and heat storage performance are rapidly deteriorated.

Step S2 of the present invention is a step of preparing a primary dispersion in which a copper-based composite is dispersed, wherein 15 to 20 parts by weight of the copper-based composite in the step S1, 1 to 5 parts by weight of a dispersant, and 75 to 84 parts by weight of an organic solvent Followed by stirring and pulverization for 1 to 10 hours using a zirconia ball mill or the like to obtain a powder having a nanometer size of the copper based composite, for example, 10 to 100 nm.

Here, the dispersant may be polyvinyl butyral, and the organic solvent may be selected from at least one of alcohol, ketone, and acetate.

Step S3 of the present invention is a step of preparing a secondary dispersion by adding calcium stearic acid or magnesium stearic acid, which is a polymer easily compatible with synthetic resin, to a primary dispersion in which a copper-based composite is pulverized into nano-size.

In step S3, the secondary dispersion may be pulverized with a zirconia ball mill or the like as in step S2, or may be omitted.

In the step S4 of the present invention, the secondary dispersion is sprayed in a spray drying method or dried in a vacuum oven at a temperature of 100 to 120 ° C to prepare a powdery nano-copper composite.

Referring to FIG. 1 again, the method for producing a fiber having an infrared ray absorbing and storing function according to the present invention comprises steps of: S5 step of providing a masterbatch for a fiber comprising 100 parts by weight of a fiber resin and 0.5 to 5 parts by weight of a nanoparticle- And a step S6 of producing a fiber by melt spinning the master batch for the fiber.

Here, since the nanoporous-based composite material has been described in detail above, detailed description thereof will be omitted.

The fiber resin may be selected from the group consisting of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), nylon, polystyrene, polycarbonate, and ABS (Acrylonitrile Butadiene Styrene).

When the amount of the nano-copper-based composite is less than 0.5 parts by weight based on 100 parts by weight of the fiber resin, it is difficult to expect infrared absorption and storage effect. When the amount exceeds 5 parts by weight, The increase rate of the effect is not so large, and the economical efficiency is significantly lowered. Therefore, it is preferable to limit the range to the above-mentioned range.

On the other hand, the fiber containing the nanoparticle-based composite according to the present invention is less costly than the fiber containing the conventional tungsten oxide and thus is not only cost competitive, but also has a nano-copper-based composite material equivalent to the oxide When added, the infrared absorption and heat storage efficiency have a further advantage.

Step S5-1 relates to a polymerization process for directly introducing the powdery nanocomposite composite into a fiber yarn manufacturing process without preparing a master batch chip (MB Chip).

For example, polyester fibers can be made by reacting EG (Ethylene Glycol) with TPA (Terephthalic acid) to form a polymer, followed by compression and spinning. At this time, it is possible to apply a method of producing a functional fiber yarn by reacting with a TPA to form a functional dispersion by nano-dispersing a nanoparticle-based composite in EG.

However, the powdery nanoparticle-based composite added in the method of step S5-1 may be added to most of the synthetic fibers.

For example, applicable synthetic fibers may be selected from the group consisting of polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), nylon, polystyrene, polycarbonate, ABS (acrylonitrile butadiene styrene) Can be exemplified.

Meanwhile, the nanoparticle-based composite according to the present invention can impart infrared absorption and heat storage performance through post-processing through a step of coating a common fiber cloth.

A dispersion for the fiber fabric to impregnate the fiber fabric is needed.

The fiber fabric dispersion is prepared by mixing 10 to 20 parts by weight of the nanoparticle-based composite particles, 1 to 2 parts by weight of a dispersant, gum arabic as a dispersant, disperbyk-190 1 to 5 By weight and stirring.

The aqueous dispersant is used for improving the dispersibility of the metal particles, and may be an anionic polyelectrolyte, a copolymer of a polymer electrolyte, a nonionic water-soluble polymer, or the like. And examples of the anionic polymer electrolyte include polyacrylic acid salts, polymethacrylic acid salts, polystyrenesulfonic acid salts and ligninsulfonic acid salts. The copolymer of the polymer electrolyte includes a polymer electrolyte and a copolymer of ethylene, acrylamide, ethylene glycol, vinyl and the like, and non-ionic polymers include polyvinyl pyrrolidone and polyvinyl alcohol. The weight average molecular weight of the aqueous dispersant is preferably 3,000 to 40,000. If the average molecular weight is less than 3,000, the effect of dispersion is deteriorated. If the average molecular weight is more than 40,000, aggregates may be formed to deteriorate the dispersibility of the metal particles. In the present invention, disperbyk-190, a polyester-based water-based dispersing agent of BYK Chemie, was used.

Disperbyk-190 described above is an aqueous dispersant dispersed in water, and its dispersion stability can be maintained for 1 to 3 months. Thus, disperbyk-190 has an advantage of being able to produce particles having low viscosity with excellent dispersibility.

Hereinafter, a method of manufacturing a nanocarpal-based composite according to the present invention will be described in more detail with reference to the preferred embodiments.

Nanoparticle-based composite manufacturing

1) 95 parts by weight of CuS precipitate, CoS precipitate and Ag ₂ S precipitate obtained by mixing CuSO ₄ solution, Co (NO ₃ ) ₂ solution and AgNO ₃ solution with Na ₂ S solution, 2 parts by weight of CoS, 2 parts by weight of Ag ₂ S were mixed in 1 part by weight, dried and pulverized, put into a sintering furnace and sintered at 300 ° C in a nitrogen atmosphere to prepare a copper-based composite.

2) 20 parts by weight of a copper-based composite, 2 parts by weight of polyvinyl butyral, and 75 to 84 parts by weight of an alcohol as an organic solvent were charged into a zirconia ball mill and stirred for 3 hours to obtain a copper- A primary dispersion is prepared. 2 is a photograph of the primary dispersion prepared in Example 1 by an electron microscope. Then, 1 to 3 parts by weight of calcium stearic acid is added as an additive based on 20 parts by weight of the primary dispersion, and the mixture is stirred and pulverized to prepare a secondary dispersion.

3) The second dispersion was sprayed by a spray dry method to complete the preparation of the nano-copper composite. 3 is a photograph of the nanoparticle composite prepared in Example 2 by an electron microscope.

[Experimental Example 1]

In this experiment, the light energy transmittance according to the sintering temperature was experimentally measured. The results are shown in FIGS. 4 to 6.

FIG. 4 is a graph showing the transmittance of the nano-copper composite prepared in Example 1 at a sintering temperature of 300 ° C., and FIGS. 5 and 6 are graphs showing transmittances of the nanoporous composite when the sintering temperatures are 500 ° C. and 700 ° C., respectively Fig.

Referring to FIG. 4, when the sintering temperature is 300 ° C as in Example 1, the transmittance is less than 10% with respect to infrared rays in a wavelength region of 2500 nm at a wavelength of 1100 nm. When the transmittance of the infrared ray is low, most of the infrared rays excluding the infra-red ray or partially reflected infrared ray absorb infrared rays, indicating excellent heat storage performance.

On the other hand, referring to FIG. 5, when the sintering temperature is 500 ° C., the transmittance is lower for the infrared ray in the 1100 nm wavelength region, but the transmittance increases linearly toward the wavelength of 2500 nm.

Referring to FIG. 6, when the sintering temperature is 700 ° C., it is confirmed that the transmittance exceeds 40% for infrared rays of 2200 nm wavelength at 1100 nm wavelength, and the transmittance exceeds 30% even for infrared rays of 2200 nm to 2500 have.

From these results, it can be confirmed that the sintering temperature is about 300 ° C. or more, and when the sintering temperature exceeds 500 ° C., the infrared absorption and heat storage performance due to the increase of the transmittance sharply decreases.

[Experimental Example 1-1]

FIG. 7 is a graph showing the transmittance of the far-infrared region of the nanoparticle composite according to Example 1. In this experiment, the tungsten oxide (left graph of FIG. 7) and the nanoparticle composite of Example 1 The transmittance in the far infrared region was compared.

Referring to FIG. 7, it can be seen that, in the case of tungsten oxide, the transmittance of the far-infrared ray having a wavelength of 2500 nm or more is significantly higher than that of the present nano-copper-based composite. As described above, since the far infrared ray transmittance of the present invention is low, the fiber fabric using the same is advantageous in that the thermal energy having a large wavelength emitted from the human body is blocked by the fiber fabric, thereby maximizing the thermal insulation performance.

2) The dispersion was impregnated with a polyester fiber fabric and then dried to prepare a fiber fabric coated with a nanoparticle-based composite of 0.2 wt% based on the total weight of the fabric fiber fabric. The fabric used in this example was gray and black.
