The present invention relates to a method for producing a silica gel pigment composition masterbatch, and in more detail, current technologies for manufacturing functional resins using minerals or antimicrobial agents that can increase the functionality of various resins and the like have been developed. As the mineral powder, plastics such as ocher, anionic mineral powder, germanium, elvan, ceramic, jade, and charcoal may be mixed with the plastic resin to obtain the functions of far-infrared radiation, anion, and deodorization of the mineral. Alternatively, you can find a wide range of advanced technologies manufactured in the form of a masterbatch. In particular, silver (Ag) can be found in various ways, such as antimicrobial preparation of silver antibacterial treatment.

As described above, the method of preparing various functional resins is mainly performed by dispersing the functional powder and the silver nano solution in the resin manufacturing process by mixing the silver colloidal solution with the mineral powder and the resin. When producing masterbatch or resin product by depositing on mineral powder or resin, especially silver nano particles are not evenly dispersed in resin, especially when pigment is used for complexing to resin, silver or particles are evenly dispersed. In addition, the pigment is not antibacterial treatment, causing a lot of problems in the product.

The present invention is to look at the technical core that can solve this problem can increase the evaporation effect of silver nano colloids and the silver nano particles are replaced by a number of porous particles of resin or mineral powder coating in the form of plating to produce a strong silver nano mineral powder The explanation is as follows.

Inorganic silver antimicrobial agent related to 'Method for producing silver salt, a new silver antimicrobial agent using bromine compound,' which the inventors have already registered a Korean patent, has a strong effect of hydrogen peroxide on the silver salt as a catalyst. In order to reduce the moisture contained in the silver colloidal solution, the silver antibacterial agent is used as a solvent of ethyl alcohol and isopropyl alcohol to prepare a highly volatile silver nano antimicrobial agent, and when hydrogen peroxide is mixed with the silver solution, 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.

The silver solution prepared as described above has excellent sterilizing power and can be confirmed to have excellent drying effect and penetration power when immersed in resin or mineral powder.

Silica gel having excellent deodorizing power is composed of transparent and semi-transparent particles, but the present invention preferably uses transparent silica gel. 1g of silica gel has a surface area of 150 m 2 or more, the better the adsorption power and the water adsorption power of sulfurous acid gas, and the lower the temperature, the greater the effect. When the silica gel is pulverized, mixed with 50% functional mineral powder (germanium, tourmaline, elvan, jade, etc.) and dried, a weak alkaline solution having a pH of about 8.5 can be obtained.

When the silver nanoparticles are adsorbed on the powder, silver is ionized in the form of plating on the inside and the outside of numerous porous particles of the mineral powder, thereby obtaining a functional silver nano antibacterial mineral having excellent antimicrobial power that does not drop even in friction or washing. In particular, it can be seen that the antimicrobial and bactericidal effects are obtained when silver nanoparticles are coated in numerous porous layers of silica gel. After preparing the powder, the silver nano solution was also immersed in a PE resin or a master beet resin to prepare a silver nano antimicrobial resin, and then the silver nano silica gel powder was mixed in a ratio of 1,000 g of the resin to prepare the functional master bezel of the present invention. It is characteristic.

When manufacturing a film by manufacturing the master bezel as described above, when using a food wrapping paper or agricultural hot-bed film, or when manufacturing a child film PP resin, etc., it is possible to produce various antibacterial, far-infrared, anionic functional resins without the occurrence of a binder phenomenon in vinyl. It is characterized by being
