Accordingly, the present invention is not limited to the drawings presented below and may be embodied in other forms, and the drawings presented below may be exaggerated to clarify the spirit of the present invention. At this time, if there is no other definition in the technical terms and scientific terms used, it has the meaning commonly understood by those of ordinary skill in the art to which this invention belongs, and the gist of the present invention in the following description and accompanying drawings Descriptions of known functions and configurations that may be unnecessarily obscure will be omitted.

One aspect of the present invention provides a base resin comprising at least one selected from the group consisting of polypropylene (PP) resin, glycol-modified polyethylene terephthalate (PETG) resin, and polycyclohexylene dimethylene terephthalate resin; ethylene-propylene-diene rubber; Zinc oxide nanoparticles surface-modified with the first silicone oil having an HLB of 2 to 8; and HLB 2 to 8, calcium oxide nanoparticles surface-modified with a second silicone oil; relates to a transparent antibacterial agent comprising a.

As such, the transparent antibacterial container according to the present invention uses at least one selected from the group consisting of polypropylene (PP) resin, glycol-modified polyethylene terephthalate (PETG) resin, and polycyclohexylene dimethylene terephthalate resin as a base resin. It can have very good transparency, and can have improved impact resistance by injection molding by mixing ethylene-propylene-diene-based rubber with this base resin.

In addition, as zinc oxide nanoparticles and calcium oxide nanoparticles are surface-modified with silicone oil having an HLB of 2 to 8 and added to the base resin, aggregation of nanoparticles is prevented, and thus the nanoparticles have targeted antibacterial properties even when a small amount is added. And it is possible to secure the deodorizing properties, there is an advantage that the transparency can not be compromised as nanoparticles can be added in a small amount.

Hereinafter, each component of the transparent antibacterial container according to an example of the present invention will be described in detail.

In an example of the present invention, the base resin may include at least one selected from the group consisting of polypropylene (PP) resin, glycol-modified polyethylene terephthalate (PETG) resin, and polycyclohexylene dimethylene terephthalate resin. can

The polypropylene resin may be used without particular limitation as long as it is commonly used in the art, and may be a homopolymer of propylene or a copolymer containing propylene, preferably a propylene random copolymer having superior transparency. . As a more specific example, the polypropylene resin has a melt index (MI, based on D1238) of 10 to 20 g/10min and a density (based on D1505) of 0.90 to 0.95 g/cm 3 to ensure excellent transparency and moldability. it is preferable to have

The glycol-modified polyethylene terephthalate (PETG) is an amorphous resin copolymerized by adding 1,4-cyclohexanedimethanol (CHDM) in the process of preparing polyethylene terephthalate (PET), and if it is commonly used in the art It can be used without particular limitation.

The polycyclohexylene dimethylene terephthalate resin is a so-called Tritan resin, which is transparent like glass, and has excellent chemical resistance, impact resistance, heat resistance and processing easiness. It can be used without limitation.

In one embodiment of the present invention, the ethylene-propylene-diene-based (EPDM) rubber is for further improving the impact resistance of the transparent antibacterial container, and may preferably be ethylene-propylene-ethylidenenorbornene rubber. By adding it, a target impact resistance property can be achieved. As a more specific example, the ethylene-propylene-ethylidene norbornene rubber may include 60 to 80% by weight of an ethylene monomer, 15 to 30% by weight of a propylene monomer, and 3 to 10% by weight of an ethylidene norbornene. When this is added to the base resin in an appropriate amount, it is possible to achieve an impact strength of 200 J/m or more while maintaining high transparency.

The EPDM rubber may be added in an amount of 5 to 15 parts by weight, preferably 8 to 12 parts by weight, based on 100 parts by weight of the base resin. In the above range, the impact resistance improvement effect and transparency are excellent. On the other hand, when the EPDM rubber is added in an amount of less than 5 parts by weight, the effect of improving the impact resistance may not be sufficient, and when it is added in an amount of more than 15 parts by weight, the haze increases.

In one embodiment of the present invention, the zinc oxide nanoparticles surface-modified with the first silicone oil having a Hydrophile-Lipophile Balance (HLB) of 2 to 8 are a component for imparting substantial antibacterial properties to a transparent antibacterial container, and zinc oxide nanoparticles As the surface of the surface is modified with the first silicone oil having an HLB of 2 to 8, aggregation between the zinc oxide nanoparticles is prevented, and even a small amount of the zinc oxide nanoparticle can be added to secure an antibacterial activity value of 4.5 or higher while maintaining high transparency. On the other hand, when the surface is not modified with the first silicone oil, zinc oxide nanoparticles must be added twice or more to secure similar antibacterial activity, and in this case, haze is increased.

On the other hand, the zinc oxide nanoparticles are modified with a first silicone oil having an HLB of 2 to 8, and a first silicone oil satisfying HLB 2 to 8, preferably a first silicone oil satisfying HLB 4 to 7, is used as a surface modifier. As a result, it is possible to more effectively prevent agglomeration of zinc oxide nanoparticles and to have excellent compatibility with the base resin. On the other hand, when silicone oil with HLB 2 or less or HLB 8 is used, the miscibility between the zinc oxide nanoparticles and the base resin after surface modification is not good, so agglomeration between the particles may become more severe. can

The first silicone oil is dimethicone, PEG-3 dimethicone, PEG-10 dimethicone, PEG/PPG-20/22 butyl ether dimethicone, cetyl PEG/PPG-10/1 dimethicone, PEG-9 polydimethylsilox It may be any one or two or more selected from the group consisting of cyethyl dimethicone, and lauryl PEG-9 polydimethylsiloxyethyl dimethicone.

The zinc oxide nanoparticles surface-modified with the first silicone oil having an HLB of 2 to 8 may be added in an amount of 0.1 to 2 parts by weight, preferably 0.3 to 1 part by weight, based on 100 parts by weight of the base resin. Antibacterial properties and transparency are excellent in the above range. On the other hand, when the zinc oxide nanoparticles surface-modified with the first silicone oil having an HLB of 2 to 8 are added in an amount of less than 0.1 parts by weight, antibacterial properties may be insignificant, and when added in excess of 2 parts by weight, the haze increases.

Meanwhile, the average particle size of the zinc oxide nanoparticles may be 1 to 100 nm, and more preferably 5 to 50 nm. In this range, the antibacterial property may be excellent.

In an example of the present invention, the calcium oxide nanoparticles surface-modified with the second silicone oil having HLB 2 to 8 are components for imparting deodorization to the transparent antibacterial container, and the surface of the calcium oxide nanoparticles is coated with the HLB 2 to HLB 2 to As it is reformed with the second silicone oil of 8, aggregation between calcium oxide nanoparticles is prevented, and even if a small amount is added, excellent deodorization performance can be secured and high transparency can be maintained. On the other hand, when the surface is not modified with the second silicone oil, similar deodorization performance can be secured only when calcium oxide nanoparticles are added twice or more, and in this case, there is a disadvantage in that the haze is increased.

On the other hand, the calcium oxide nanoparticles are modified with a second silicone oil having an HLB of 2 to 8, a second silicone oil satisfying HLB 2 to 8, preferably a second silicone oil satisfying HLB 4 to 7, is used as a surface modifier As a result, it is possible to prevent agglomeration of calcium oxide nanoparticles more effectively and to have excellent compatibility with the base resin. On the other hand, when silicone oil with HLB less than 2 or HLB greater than 8 is used, the miscibility between the calcium oxide nanoparticles and the base resin after surface modification is not good, so the aggregation between particles may become more severe, and thus deodorization performance and impact strength are lowered. can be

The second silicone oil is dimethicone, PEG-3 dimethicone, PEG-10 dimethicone, PEG/PPG-20/22 butyl ether dimethicone, cetyl PEG/PPG-10/1 dimethicone, PEG-9 polydimethylsilox It may be any one or two or more selected from the group consisting of cyethyl dimethicone, and lauryl PEG-9 polydimethylsiloxyethyl dimethicone, and may be the same as or different from the first silicone oil.

More preferably, the viscosity of the second silicone oil may be 100 to 1000 cS, and more preferably 400 to 800 cS. Within this range, the surface modification effect of the calcium oxide nanoparticles may be excellent.

The calcium oxide nanoparticles surface-modified with the second silicone oil having an HLB of 2 to 8 may be added in an amount of 0.1 to 2 parts by weight based on 100 parts by weight of the base resin, and more preferably 0.3 to 1 part by weight. In the above range, deodorization performance and transparency are excellent. On the other hand, when the calcium oxide nanoparticles surface-modified with the second silicone oil having an HLB of 2 to 8 are added in an amount of less than 0.1 parts by weight, the deodorizing performance may be insignificant, and when added in excess of 2 parts by weight, the haze increases.

On the other hand, the average particle size of the calcium oxide nanoparticles may be 1 to 200 nm, more preferably 10 to 100 nm. In this range, the deodorization performance may be excellent.
