The present invention is a method for producing a functional masterbatch using a new silver nano white charcoal composition. In more detail, a method of electrolytically dissolving silver (Ag) into small particles as nanoparticles and chemically melting silver into small nanoparticles There is a way.

It is reported that there are no germs or viruses that survive for 6 minutes after contact with silver, and it is highly regarded as an inorganic antibacterial agent that is harmless to humans and sterilizes all germs and is considered to be the safest antibacterial metal on earth. Various technologies can be found for manufacturing master batches or resin chips by depositing various plastics or mineral powders and mixing them in plastic resins at a constant ratio.

As mentioned above, when silver nanocolloids are electrolyzed, many problems are encountered in dissolving high ppm silver particles in water. Chemical colloids can be found in advanced technologies for small particles of silver (Ag) into nanoparticles, which can increase the content of silver (Ag).

To date, silver nanoparticles are deposited on plastics or mineral powder and plastic raw materials to produce silver antibacterial masterbatch compositions. Silver colloids are water-soluble, so they are adsorbed on these resins or minerals and dried to produce silver nanocomposite masterbatches, thus removing moisture. Not only is it a problem, but silver is not well dispersed in resin, mineral or charcoal powder. In addition, silver (Ag) nanoparticles are yellowed when they are deposited by resin raw materials, mineral powders, etc., and resinized or when yarns are discharged, which is a problem to the product. To date, silver nano-colloidal products are characterized by silver nano-colloids that cause yellowing when combined with alkali salts, iron salts, halogen compounds or heavy metals.

The present invention is characterized by producing a silver nano-colloid that can solve this problem. The present inventors have already registered the Republic of Korea patent No. 0399481 New antimicrobial agent using bromine compound In using silver colloidal solution of silver salt preparation, 100 ml of hydrogen peroxide (31.2%) is mixed and mixed with 1,000 g of silver solution for strong silver nano oxidation After preparing the composition, 500 ml of ethyl alcohol and 400 ml of isopropyl alcohol are mixed and mixed to prepare a silver solution containing 150,000 ppm in 1,000 g of silver nano composition having excellent oxidation, reduction, antibacterial and bactericidal properties.

In the present invention, when combined with the silver nano-colloid and hydrogen peroxide explosive decomposition can be obtained silver nano-colloid with excellent oxidation and reducing power, as well as bactericidal and antimicrobial effect. At this time, when hydrogen peroxide and silver solution are combined, the following characteristics can be found.

When oxygen peroxide and silver solution combine, active oxygen compounds are generated. The difference is that radical and anion have strong kine energy due to the interaction between silver and hydrogen peroxide molecules. Therefore, it passes through the cell wall 10 to 100 times stronger than hydrogen peroxide, and negatively charged -O-O-H also can destroy the cell wall with higher kinetic energy.

When the silver nano solution is prepared as described above, it is possible to obtain a silver nano solution having excellent sterilization and penetration ability as well as a solvent type silver nano colloid having excellent volatility.

As a core technology of the present invention, a method of ionizing silver nanoparticles inside and outside a number of porous interiors of white coal is described as follows.

The white charcoal produced by the present invention was deposited by drying white charcoal in a solution in which oak of about 10 cm in length and 5 cm in diameter was mixed with 20 g of hydrochloric acid and 50 g of hydrochloric acid in 1,000 ml of water. When the solution is deposited in a stainless steel container (150,000 ppm) and the white charcoal composition is deposited, silver nanoparticles are deposited on numerous porous outer and inner parts of the white charcoal and ionized in a plating form that is difficult to identify even by an electron microscope. The white charcoal is dried and pulverized to about 1,000 mesh to prepare a strong silver nano antimicrobial charcoal.

In addition, as a functional mineral material, tourmaline aka tourmaline and tourmaline aka tourmaline and germanium, jade, ceramic powder, which are minerals of far-infrared radiation, may be used, but in the present invention, the silver nanocolloid is immersed in the powder pulverized tourmaline and dried again to 1,000 mesh. The pulverized silver nano tourmaline powder is prepared.

In addition, a resin such as PE or PP may be used according to the purpose of the master beech resin, but in the present invention, by dipping 1,500 ppm of silver nano solution in a ratio of 1,000 g of PE resin chip, and preparing 1,000 g of antimicrobial resin chip, the present invention According to the drawings for the production of a functional masterbatch using the new silver nano white charcoal composition of 100 g of silver nano white charcoal in which the silver resin is deposited, the ratio of 1,000 g of silver nano white charcoal is quantified in the quantification step (1), and then a constant amount is added to the input step (2). Into the mixer (3), and evenly mixed, and then extruded a certain amount by the injection process (4) to the extrusion process (5), through the cooling process (6) in the cut (7) process about 2mm in diameter, about 3mm in length It is characterized by manufacturing a functional masterbatch in the form of a chip of a certain standard. 50 kg of the functional white charcoal composition prepared as described above was mixed and mixed with 1,000 g of a PP resin to spun yarn with a thickness of about 2 danes, and then cut to a certain size to prepare a cottony pulp type filter, and then the filter type cotton Silver nano white charcoal composition non-woven fabric through non-woven fabric manufacturing process and used in earrings or sanitary napkins, clothing, antibacterial filter, etc., has excellent antibacterial effect, does not inhabit bacteria, and prevents anion and far infrared rays, deodorization, dehumidification, antistatic There is a great effect on the human body and the environment.
