  The above-mentioned conventional patents and their posted technical contents are all quite different from the technical contents of the patent to be applied for this time, and the patented technical contents of the present application are not only innovative but have unique effects. . This is therefore the purpose of the present application.

  The methods described in the above-mentioned conventional patent documents are complicated and have a limited effect, and further, no technology related to the technical contents of the present application is posted. The “composite powder that releases negative ions with high efficiency, the deposit of the composite powder, and a method for producing the same” of the present invention is based on the related experience that the inventor has been engaged in in this direction for several years. It has been developed and designed through earnest research and experimentation, and according to the related science.

  A main object of the present invention is to provide a composite powder that releases negative ions with high efficiency, a deposit of the composite powder, and a method for producing the same. Is it possible to produce composite powder from tourmaline powder and charcoal powder according to the optimized mixing ratio and adhere to the composite powder? (For example, a polymer foam material or chemical fiber material) is added and melted to create a product, and the product is synergistic and highly piezoelectric after mixing the tourmaline powder and carbonaceous powder. Thermoelectric or related physical properties can be obtained, and multi-functional effects such as mass release of negative ions, deodorization and antibacterial can be exhibited. Further, the production method of the present invention is simple and quick, is easy to mass-produce, and therefore has a very high industrial application value.

  In order that the technical means and operation process of the present invention can be more clearly recognized and understood, an embodiment will be given and described in detail with reference to the drawings.

  The present invention is “a composite powder that releases negative ions with high efficiency, a deposit of the composite powder, and a method for producing the same”. The composite powder of the present invention is composed of at least one ore composition and other mineral powders, the main component of the composite powder is tourmaline powder, and a predetermined proportion of carbonaceous powder. By adding it as an auxiliary component, the electric field effect of tourmaline fine particles is improved, and the multifunctional effects such as release of negative ions, deodorization and antibacterial are promoted. The tourmaline powder is iron tourmaline (schorl), lithia tourmaline (elbaite), manganese-lithia tourmaline (rubellite), cesium tourmaline (goshenite) or magnesium tourmaline (dravite). The charcoal powder may be bamboo charcoal, coconut charcoal, activated carbon, charcoal, or the like.

  In the present invention, the blending ratio of the composite powder is such that the composite blending ratio of tourmaline powder and charcoal powder is 1-20: 99-80, and the average powder particle size of the tourmaline powder is as follows. Is 0.3 μm to 1 μm, and the average powder particle size of the carbonaceous powder is 5 μm to 20 μm.

  Hereinafter, the composite powder (tourite powder / charcoal powder) will be further described. The charcoal (for example, bamboo charcoal) powder in the composite powder is in the form of pellets, and as can be seen from the elemental analysis of the surface, bamboo charcoal is a porous substance and the distribution of pore gaps inside it Are very wide and the fine pores in these different size apertures have a strong adsorption capacity.

  As shown with reference to FIG. 1, this is a schematic view of a scanning electron microscope (abbreviated as SEM) of a sample of the composite powder of the present invention, which can be clearly seen from the figure. Thus, pores of these different dimensions are distributed on the surface of the bamboo charcoal pellets, and the elemental composition at both points is different, as can be seen through both elemental analysis of A and B on the surface of the bamboo charcoal. Explain that both points of B and B are composed of two different substances, and as can be seen from the results of elemental analysis (EDX), the tourmaline powder pellets are mainly oxygen (O) and aluminum (Al). , Silicon (Si), iron (Fe) and sodium (Na) and other elements, among which the oxygen (O), aluminum (Al), silicon (Si) and iron (Fe) elements total 95 Exceeds weight percent (wt%).

  The bamboo charcoal pellets mainly contain carbon (C) element, but the proportion of the charcoal exceeds 95% by weight (wt%). It fills in the pore gaps on the pellet surface to form one “mixture”.

  Therefore, by adding a predetermined proportion of bamboo charcoal powder to the tourmaline powder and closing the tourmaline powder in the network structure of the bamboo charcoal, the tourmaline powder is further made piezoelectric. The bamboo charcoal powder has thermoelectric properties and good conductivity characteristics, and both powders are filled in a base material to form a three-dimensional micro conductive network. Therefore, an excellent integrating action is acquired and the negative ion release effect is promoted.

  When the tourmaline powder and the bamboo charcoal powder are mixed at a predetermined rate, the average air negative ion release concentration measured under the static test condition at 90 ° C. reaches 1480 / cc. Similarly, when the composite powder is mixed from the tourmaline powder and the bamboo charcoal powder in the same proportion at a predetermined rate, the average air negative ion release concentration is 800 to 1480 / cc, respectively. , Both are higher than other proportions of the composite powder. This is because the tourmaline powder itself has thermoelectric properties, and therefore when the tourmaline powder and the bamboo charcoal powder in the composite powder are mixed at a predetermined ratio, the tourmaline powder Can be distributed uniformly and in an appropriate amount in the hole of the bamboo charcoal powder, leading to the generation of a thermal / piezoelectric effect, and the effect of releasing negative ions increases as the temperature increases.

  Further, FIG. 2 is an analysis schematic diagram in which the ratio of the content of the composite powder of the present invention is relative to the release concentration of negative ions. As can be clearly seen from the figure, the average air negative ion release concentration of the composite powder increases as the temperature increases. For example, under the 90 ° C static test condition, When the tourmaline powder and bamboo charcoal powder in the composite powder are mixed, the release concentration of the air negative ion is about 1480 / cc at the maximum, and about 2.8 times the measurement under the 35 ° C static test condition. Become.

  FIG. 3 is an analysis schematic diagram of the conductivity of the composite powder solution at different temperatures according to the present invention. As can be clearly seen from the figure, the bamboo charcoal solution in the composite powder effectively dissociates water molecules in water through contact between water molecules to form negative ions, improves conductivity, and There is a tendency to increase the conductivity with the temperature, which is consistent with the tendency to change the average air negative ion emission concentration of the composite powder sample with the temperature. In conclusion, this conclusion proves that the composite powder has remarkable thermoelectric properties in liquid water or air.

  In addition, according to the present invention, the composite powder can be added to the deposit, and the deposit may be a polymer material. The polymeric material broadly refers to all thermoplastic and / or thermosetting elastomeric materials (eg, ethylene propylene diene monomer (EPDM) / polypropylene (PP) or EPDM, PP, PU, etc.). May also be a foam-type product made of foam material (eg polyurethane (PU), polyethylene (PE), polypropylene (PP), polystyrene (PS), etc.), subject to the elasticity and extrusion of the foam itself By utilizing the compression characteristics of, tourmaline exerts its own piezoelectric and thermoelectric effects, and achieves multi-functional effects such as a large amount of air negative ion release, deodorization and antibacterial. The polymer material may be a textile product made of a chemical fiber material (for example, polyethylene glycol terephthalate (PET), polypropylene (PP), nylon fiber (Nylon), etc.), thus releasing negative ions and deodorizing. And multi-functional effects such as antibacterial (as shown in Tables 1 and 2 below).

  As a result, the average content of optimization of the thermoplastic and / or thermosetting elastomer material in which the composite powder (tourmaline powder / charcoal powder) is added to the polymer material will be described below.

  As shown with reference to FIG. 4, when the composite powder content increases from 0.5 weight percent (wt%) to 10 weight percent (wt%), it disperses in the thermoplastic elastomer sample. When the average particle size increases from 8.5 μm to 38.8 μm, approximately 2 to 13 times the original particle size, and when the content of the composite powder increases from 0.5 wt% to 10 wt%, the heat The average particle size dispersed in the plastic / thermosetting elastomer sample increases from about 5.7 μm to 15.7 μm, approximately 1 to 6 times the original particle size, under extremely similar conditions. Slightly smaller than the average particle size in the thermoplastic elastomer sample.

  Further, in the thermoplastic elastomer sample, when the content of the composite powder is increased from 0.5 wt% to 5 wt%, the average particle size dispersed in the thermoplastic elastomer sample is only 8.5 μm to 18.6. When the content of the composite powder increases from 5 wt% to 10 wt%, the average particle size dispersed in the thermoplastic elastomer sample increases from 18.6 μm to 38.8 μm. improves.

  There is a similar tendency in the thermoplastic / thermosetting elastomer samples, but only when the composite powder content increases from 0.5 wt% to 5 wt%, the thermoplastic / thermosetting When the average particle size dispersed in a sample of elastomer increases slowly from 5.7 μm to 8.5 μm and the content of the composite powder increases from 5 wt% to 10 wt%, the thermoplastic / thermosetting The average particle size dispersed in the elastomeric sample increases significantly from 8.5 μm to 15.7 μm.

  From the above results, the thermoplastic elastomer (for example, PP) and the thermoplastic / thermosetting elastomer (for example, EPDM / PP) are more preferable when the content of the composite powder is lower than 5 wt% during the processing. It can be assumed that a significant agglomeration phenomenon is generated when the content of the composite powder is higher than 5 wt%.

  In the following, for pure thermoplastic / thermosetting elastomer samples and composite / powdered thermoplastic / thermosetting elastomer samples, the average air negative ion release concentration under various test conditions is further explained. .

  As shown with reference to FIG. 5, the sample of the pure thermoplastic / thermosetting elastomer has an average air negative ion release concentration of only 30 / cc in each of the 25 ° C. static test conditions. After the composite powder is mixed into the plastic sample of the pure thermoplastic / thermosetting elastomer, the average air negative ion release concentration increases as the content, temperature and pressure of the composite powder increase. It is remarkably increased that it is worth noting that when the content of the mixed composite powder is close to the optimized value, the average air negative ion release concentration reaches the maximum value, for example, at 25 ° C The average air negative ion release concentration is about 270 and 400 / cc, respectively, which is more than 6 times the average air negative ion release concentration of pure thermoplastic / thermosetting elastomer samples under similar measurement conditions. It becomes.

  Since the tourmaline powder itself has both thermoelectric and piezoelectric properties, it mixes the thermoplastic / thermosetting elastomer sample of the composite powder and the pure thermoplastic / thermosetting elastomer sample. The average air negative ion release concentration under both improvement and pressure changes is slightly higher than the result at room temperature, but when the temperature exceeds 50 ° C, the thermoplastic / There is a possibility of accelerating the evaporation movement of water near the sample of thermosetting elastomer, and thus contributes to the ionization action of tourmaline powder to water in the air, so the average air negative ion release concentration is also slightly higher Because it becomes.

  Tourmaline powder has a piezoelectric effect, so any sample of thermoplastic / thermoset elastomer under similar tourmaline powder content is more than a sample of pure thermoplastic / thermoset elastomer. It leads to having a preferable negative ion release effect. Bamboo charcoal powder itself has an effect of releasing negative ions, and by adding an appropriate amount as an auxiliary component, the electric field effect of tourmaline powder is improved. This improves the negative ion release effect.

  In addition, the composite powder produced by the present invention may be a polymer material to which an adhering substance can be added, and the adhering substance can have a spinning or foaming level condition. Plastic and / or thermoset elastomeric materials and other fiber or foam materials (polyethylene (PE), polypropylene (PP), ethylene propylene diene monomer (EPDM), ethylene vinyl acetate (EVA) and artificial rubber, eg styrene butadiene It refers to polymer materials that can be regarded as rubber (SBR) and polycresol resins (including polymer materials such as neoprene that can be increased), and is formed in a masterbatch type system, so that Under temperature conditions, the polymer material to be added (eg nylon, polyester, polypropylene, polyethylene) Are produced via a specific addition method. Among these, the specific addition method is spray, mechanical mixing, or other gas or liquid fluids.
