1 and 2, the sticker peel capable of three-dimensional expression according to the present invention The antibacterial sofa according to the present invention comprises a frame 100, and an antibacterial film 200 adhered to the surface of the frame 100.

The frame 100 supports the backrest or cushion constituting the sofa, or includes armrests located on both sides, and is made of wood, iron, etc. other than the backrest, cushion, and cushion to support the load of the user.

Since the configuration of the frame 100 in the present invention is a known technique, a detailed description thereof will be omitted for convenience of explanation and clarity of the technical idea of the present invention.

The antibacterial film 200 may be adhered to the surface of the frame 100 to provide antibacterial, anti-odor and deodorant properties to the sofa, and the antibacterial film 200 is a base layer 220, and the base layer ( 220) and a coating layer 240 formed by coating the surface.

The TPV (Thermo Plastic Vulcanizate; thermoplastic crosslinked elastomer) resin has excellent insulation, heat resistance, and cold resistance. The TPV resin is a resin having both thermoplasticity and rubber elasticity, and crosslinked ethylene-propylene-diene rubber (EPDM) and polypropylene It refers to a composition containing as a main component.

In general, TPV (Thermo Plastic Vulcanizate; thermoplastic crosslinked elastomer) resin is a simple blend type thermoplastic elastomer (TPO) in which rubber components are simply mixed without any crosslinking component, depending on the degree of crosslinking of the elastomer, and partially crosslinked thermoplastic elastomer. It is classified into a crosslinked elastomer (TPR) and a fully crosslinked thermoplastic crosslinked elastomer (TPV) that is fully crosslinked.

In addition, this degree of crosslinking affects the fine dispersibility of the rubber component in the TPV resin, and in turn, affects elastic properties such as tensile strength, permanent elongational settling rate, and permanent compression settling rate. Specifically, in the case of TPO without crosslinking or TPR with a low degree of crosslinking, there is a limit to making the rubber phase into a uniform fine dispersed phase by shear stress. In particular, as the content of rubber increases, it becomes more difficult to obtain a fine dispersed phase. . For this reason, in a material requiring thermoplasticity and excellent elasticity, dynamic crosslinking is performed in which the rubber phase is physically pulverized into fine particles by shear stress during crosslinking.

The TPO (Thermo Plastic Polyolefine; thermoplastic polyolefin-based elastomer) resin has excellent tensile strength and processability, and the TPO resin has excellent weather resistance, excellent flexibility at low temperatures, excellent adhesion, and harmful substances, odors, and dust generation during operation.

The copper nanoparticles inhibit the growth of bacteria by themselves and improve the metabolism of various microorganisms. It can provide antibacterial and deodorizing properties, such as removing the cause of unpleasant odors by interfering.

For example, copper oxide nanoparticles may be used as the copper nanoparticles, and the copper oxide nanoparticles are surface-modified by stirring 0.1 to 2 parts by weight of silane with respect to 100 parts by weight of copper oxide powder having a particle size of 1 to 200 nm. Copper oxide nanoparticles prepared by making it can be used.

That is, since the surface of the copper oxide powder is generally hydrophilic, it cannot be dispersed in the resin by the OH group and may coagulate, but in the present invention, as the surface of the copper oxide powder is modified with silane as described above, the SIOH group and oxidation of the silane By bonding by causing hydrolysis between the OH groups on the surface of the copper powder, the hydrophobic OR group in the silane is positioned on the surface of the copper oxide powder to improve dispersibility due to the repulsive force between the OR groups, that is, the repulsive force between the copper oxide powders.

In addition, the silane is vinyltriethoxysilane, vinyltrimethoxysilane, or vinyltri(2-methoxyethoxy)silane (Vinyltri(2-methoxyethoxy) to improve dispersibility as described above. silane), but is not necessarily limited thereto, and various known silanes can be used.

In the present invention, the copper powder may be included in a weight ratio of 3 to 7 parts by weight of the total content of the composition forming the base layer 220. When the copper powder is included in less than 3 parts by weight, antibacterial and deodorizing properties are imparted. The effect is insignificant, and when it is included in excess of 7 parts by weight, there may be a problem in that the physical properties of the prepared base layer 220 are deteriorated.

As the flame retardant, a bromine-based flame retardant may be used. In general, the halogen flame retardant acts competitively with oxygen for radicals generated in the combustion process, and the halogenated radicals do not propagate a chain reaction, so that the fire is turned off.

Specifically, active radical OH and active radical H, which play a role of propelling combustion, are trapped and stabilized by HX. HX is non-flammable and has an effect of blocking oxygen with a dilution effect, thereby exhibiting flame retardancy.

Of the halogens, iodine is the most effective flame retardant element, but it is expensive and lacks heat resistance and light resistance, and chlorine and fluorine have very poor or no effect on radical trapping.

On the other hand, bromine is the second most effective flame retardant element after iodine and is most widely used because it can produce a high flame retardant effect in a small amount that does not affect the physical properties of the polymer. In particular, the phenomenon that only traces of carbonization are visible after extinguishing is a distinctive feature from existing flame retardants.

It may be selected from the group, and preferably, the flame retardant aid may be used by mixing antimony trioxide and antimony pentoxide in a weight ratio of 1:1.

The antimony compound itself has extremely limited flame retardancy, but exhibits a synergism effect that greatly increases the radical trapping effect when combined with a halogenated flame retardant.

Typically, the antimony trioxide reacts with halogen _{to generate SbOCl and SbCl 3} , SbCl produces HCl to exhibit a radical trapping effect, SbCl _{3 is} also a heavy gas and exhibits a shielding effect of oxygen, and SbOCl exhibits dehydrocarbonation. do.

The expanded graphite powder is a powder of expanded graphite. In general, graphite is a mineral in which planar macromolecules in which 6-membered rings of carbon atoms are infinitely connected in a plane are layered on top of each other, and its properties are good conductors of electricity and polycenes. It is flexible and active due to its layered structure, and although it is easy to be cleaved, it is a macromolecule and therefore has low reactivity.

However, in graphite, since the carbon planes of the polycene structure are only connected by van der Waals force, the gap between carbon atoms is 35.5 nm wider than 14.2 nm, so other atoms are inserted in the gaps between the layers to create an interlayer compound. can That is, while maintaining the network plane of the graphite crystal, many atoms, molecules, or ions are inserted into the gaps between the planes to create an interlayer compound.

That is, when an interlayer compound or residual compound coated with an acid such as sulfuric acid between layers of graphite is rapidly heated to a temperature close to 1000°C, the acid is vaporized to generate gas, and the interlayer of graphite is separated by several tens to hundreds by the expansion pressure of the gas. It expands into a ship, which is called expanded graphite.

The expanded graphite powder expands 30 to 50 times in the process of raising the temperature to 180° C. or more during a fire, and forms char, so that it can serve to impart flame retardancy with non-combustibility.
