상기 항균물질은, 멘톨, 프로폴리스, 및 플라보노이드의 그룹으로부터 선택되는 1가지 이상을 사용할 수 있다.The antibacterial material may be one or more selected from the group of menthol, propolis, and flavonoids.

일반적으로 사용되는 주석산은 물에 대한 용해도가 낮아 수지에 혼입할 경우 고농도로 적용되기 어려워 제형에 제한이 있으므로, 주석산 염 형태로 항균물질과 이온결합을 유도하여 용해도 및 안정성을 개선할 수 있다. Since tartaric acid generally used has low solubility in water, it is difficult to apply it at high concentration when incorporated into a resin, so there is a limitation in formulation.

상기 항균물질과 주석산 염은 특정 작용기의 부분 전하에 의한 쌍극자간 결합으로 인해 공융혼합물을 형성할 수 있고, 이들의 화학 구조를 통해 상기 범위의 몰비에서 항균성 공융혼합물을 형성할 수 있다.The antibacterial substance and the tartrate salt may form a eutectic mixture due to the dipole bond due to the partial charge of a specific functional group, and through their chemical structure, an antimicrobial eutectic mixture may be formed at a molar ratio in the above range.

상기 주석산 염의 몰비율이 1을 초과하면 항균물질과 이온결합을 하지 못하고 남는 주석산 염 분자들이 물에 대한 용해도를 초과하여 저온에서 석출될 수 있다.When the molar ratio of the tartrate exceeds 1, the tartrate molecules remaining without ionic bonding with the antibacterial material may be precipitated at a low temperature in excess of solubility in water.

상기 항균성 공융혼합물은 침전물이 없는 투명상을 갖는다.The antimicrobial eutectic has a clear phase without precipitates.

상기 가소제는, 다음의 반응식 5와 같이 다이아이소노닐 프탈산(Diisononyl phthalate)을 수소반응(hydrogenation)시킴으로서 1-2 사이클로헥산 디카르복실산 다이아이소노닐 에스테르를 제조하여 사용한다.The plasticizer is used by preparing 1-2 cyclohexane dicarboxylic acid diisononyl ester by hydrogenation of diisononyl phthalate as shown in Scheme 5 below.

상기 1-2 사이클로헥산 디카르복실산 다이아이소노닐 에스테르는 밀도 0.944 ~ 0.954 g/cm3, 점도 44 ~ 60 mPa*s인 것을 사용한다.The 1-2 cyclohexane dicarboxylic acid diisononyl ester uses a density of 0.944 to 0.954 g/cm 3 , and a viscosity of 44 to 60 mPa*s.

상기 보호제는, 하나 이상의 금속 인산염(metal phosphates)을 포함하고, 입자 형태로 평균 크기는 0.5 내지 10 μm인 것을 사용한다.The protective agent includes one or more metal phosphates, and has an average size of 0.5 to 10 μm in the form of particles.

상기 금속 인산염은 인산아연(zinc phosphate)을 사용한다.The metal phosphate is zinc phosphate.

상기 금속 인산염은 입자 크기가 0.5 내지 10 μm인 경우에 가소제와 혼합시 단단한 응집 혼합물을 형성함으로써 코팅층의 부식을 방지하여 내구성을 향상시키는데 도움을 준다.When the metal phosphate has a particle size of 0.5 to 10 μm, it helps to improve durability by preventing corrosion of the coating layer by forming a hard cohesive mixture when mixed with a plasticizer.

상기 고분자 결합제는 알키드 폴리우레탄(alkyd polyurethane), 폴리비닐 부티랄(polyvinyl butyral) 중에서 선택되는 하나 이상을 포함한다.The polymer binder includes at least one selected from alkyd polyurethane and polyvinyl butyral.

상기 고분자 결합제는 상기 가소제 및 보호제를 운반하여 결합시키는 역할을 하며, 혼합 과정에서 발생하는 전단력을 방지할 뿐만 아니라 보호제 내에 있는 인산염의 부하를 감소시켜 가소제 및 보호제의 표면 특성이 크게 변하지 않고 우수한 기계적 물성을 유지할 수 있도록 한다.The polymer binder serves to transport and bind the plasticizer and the protective agent, and not only prevents the shear force generated during the mixing process, but also reduces the load of phosphate in the protective agent, so that the surface properties of the plasticizer and the protective agent are not significantly changed and excellent mechanical properties to be able to maintain

상기한 구성에 의한, 본 발명의 일실시예에 따른 항균 기능을 구비한 소파 및 그의 제조방법의 작용은 다음과 같다.According to the above configuration, the operation of the sofa and its manufacturing method having an antibacterial function according to an embodiment of the present invention is as follows.

먼저, 소파 프레임을 제조한다(S10).First, a sofa frame is manufactured (S10).

다음에, 소파 커버링원단을 준비한다(S20). 소파 원단으로서는 천연가죽, 인조가죽, 파샤, 패브릭, 사무드, 세르텍스, 라무스, 플로킹 등이 있다.Next, prepare a sofa covering fabric (S20). Sofa fabrics include natural leather, artificial leather, pasha, fabric, samud, certex, ramus, and flocking.

이어서, 알코올기를 가지는 항균물질과, 주석산 염을 1~4 : 1의 몰비율로 공융혼합한 후, 산화아연을 더하여 항균성 공융 혼합물을 제조한다(S30).Next, an antibacterial substance having an alcohol group and a tartrate salt are eutectic-mixed in a molar ratio of 1-4: 1, and then zinc oxide is added to prepare an antimicrobial eutectic mixture (S30).

다음에, 다이아이소노닐 프탈산(Diisononyl phthalate)을 수소반응(hydrogenation)시킴으로써 비프탈레이트계 가소제로서 1-2 사이클로헥산 디카르복실산 다이아이소노닐 에스테르를 제조한다(S40).Next, diisononyl phthalate is hydrogenated to prepare 1-2 cyclohexane dicarboxylic acid diisononyl ester as a non-phthalate-based plasticizer (S40).

상기 가소제는 석유자원에서 합성되는 기존의 환경호르몬 유발물질을 발생시키지 않으면서도, PVC 수지 조성물에 혼합함으로써 가소제 본연의 성능인 PVC의 유연성을 증가시켜서 가공성을 용이하게 할 수 있다.The plasticizer can facilitate processability by increasing the flexibility of PVC, which is the original performance of the plasticizer, by mixing it with the PVC resin composition without generating the existing environmental hormone-inducing substances synthesized from petroleum resources.

이어서, PVC 수지에 상기 항균성 공융 혼합물 및 상기 가소제, 그리고 보호제와 고분자 결합제를 혼합하여 코팅제를 제조한다(S50).Then, a coating agent is prepared by mixing the antimicrobial eutectic mixture, the plasticizer, and the protective agent and the polymer binder in the PVC resin (S50).

다음에, 소파 커버링원단에 코팅제를 도포함으로써 코팅층을 형성한다(S60). 이 경우에 소파 커버링원단의 재질에 따라 소파 커버링원단 전체를 코팅할 수도 있고, 소파 커버링원단을 부분적으로 코팅할 수도 있다. Next, a coating layer is formed by applying a coating agent to the sofa covering fabric (S60). In this case, depending on the material of the sofa covering fabric, the entire sofa covering fabric may be coated, or the sofa covering fabric may be partially coated.

이어서, 코팅제가 도포된 소파 커버링원단을 건조시킨다(S70).Then, the sofa covering fabric coated with the coating agent is dried (S70).

다음에, 건조가 완료된 소파 커버링원단을 재단한다(S80).Next, the drying finished sofa covering fabric is cut (S80).

이어서, 재단되어 있는 소파 커버링원단을 재봉한다(S90).Then, the cut sofa covering fabric is sewn (S90).

다음에, 소파 프레임에 소파 커버링원단을 커버링함으로써 소파를 제작한(S100).Next, the sofa was manufactured by covering the sofa covering fabric on the sofa frame (S100).
