자동차용 숯 시트 제조방법{A motorcar charcoal seat manufacturing method} A charcoal seat manufacturing method for automobiles

본 발명은 폴리우레탄폼(polyurethane foam)으로 구성된 자동차용 숯 시트 제조방법에 관한 것으로서, 항균성과 악취제거성을 갖는 숯을 분말로 만들어 폴리우레탄과 함께 발포 성형하되 폴리우레탄의 제조에 필요한 물이 숯에 흡수되지 않도록 전처리과정을 거쳐 발포함으로써, 폴리우레탄의 물성 변화 없이 항균성 시트를 만들 수 있는 자동차용 숯 시트 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a charcoal sheet for automobiles composed of polyurethane foam, wherein the charcoal having antibacterial and odor removing properties is made of powder and foamed together with polyurethane, but the water required for preparing the polyurethane is charcoal. By foaming through a pretreatment process so as not to be absorbed in, it relates to a method for manufacturing a charcoal sheet for automobiles that can make antimicrobial sheets without changing the physical properties of the polyurethane.

일반적으로 자동차용 시트는 우레탄을 금형 내부에 발포하여 만든 것으로써 우레탄은 스프레이 형태로 금형 내부에 발포되기 때문에 시트를 원하는 모양으로 쉽게 제작할 수 있다.In general, a car seat is made by foaming urethane into a mold, and since urethane is foamed into a mold in a spray form, the seat may be easily manufactured in a desired shape.

폴리우레탄 시트는 촉매가 배합된 폴리올에 물을 섞은 뒤 별도의 이소시아네이트와 혼합하고 이를 금형 내부에 발포 성형한 것이다.Polyurethane sheet is a polyol containing a catalyst is mixed with water and then mixed with a separate isocyanate and foamed into the mold.

최근에는 숯을 이용한 제품들이 많이 개발되고 있으며 이를 자동차 시트에 적용하기 위해 연구중에 있다. 숯은 항균성과 악취제거성이 우수하기 때문에 오래된 시트에서 발생되는 악취 또는 곰팡이 등의 세균 증식을 억제시킬 수 있다.Recently, many products using charcoal have been developed and are being researched for application to automobile seats. Charcoal has excellent antibacterial and odor removal properties, which can inhibit bacterial growth such as odors or molds generated in old sheets.

그러나 숯 분말을 폴리올에 배합하는 과정에서 숯이 물을 흡수하기 때문에 폴리올과 물의 화학반응이 불충분하여 폴리우레탄의 물성이 변하고 원하는 경도와 완충성을 갖는 폴리우레탄 시트를 만들 수 없었다.However, since the charcoal absorbs water in the process of blending the charcoal powder into the polyol, the chemical reaction between the polyol and the water is insufficient, and thus the polyurethane sheet cannot be changed and the polyurethane sheet having the desired hardness and buffering property cannot be produced.

따라서 종래에는 숯을 이용하여 시트를 만드는데 기술적으로 어려움이 있었다.Therefore, in the prior art, there was a technical difficulty in making a sheet using charcoal.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 폴리우레탄의 원료인 폴리올에 물을 혼합하기 전에 물이 혼합되지 않은 일부 폴리올에 숯분말을 혼합하여 이들 물이 혼합된 폴리올과 숯분말이 혼합된 폴리올을 이소시아네이트와 한곳에서 동시에 혼합하고 금형 내부로 발포함으로써, 폴리올에 필요한 물을 숯이 흡수하지 않음으로 폴리우레탄의 물성 변화 없이 원하는 내구성을 갖는 시트를 만들 수 있으며, 특히 시트에 숯 분말이 첨가되어 있음으로 항균성과 악취제거성이 우수하고 또한 심신 안정과 음이온 발생, 공기정화 및 전자파 흡수효과 등의 다양한 기능을 발휘할 수 있는 자동차용 숯 시트 제조방법을 제공함에 있다. The present invention was developed in view of the conventional problems, and an object of the present invention is to mix charcoal powder with some polyols in which water is not mixed before mixing water with polyol which is a raw material of polyurethane, By mixing polyol mixed with charcoal powder at the same time with isocyanate and foaming into the mold, charcoal does not absorb the water required for the polyol, thus making the sheet having the desired durability without changing the physical properties of the polyurethane. With the addition of charcoal powder, it provides an antibacterial and odor removal method, and also provides a method for manufacturing a charcoal sheet for automobiles that can exhibit various functions such as mental and physical stability, negative ion generation, air purification and electromagnetic wave absorption effect.

상기 목적을 달성하기 위하여 본 발명은 하부금형에 폴리우레탄을 발포하여 폴리우레탄층을 형성하는 공정, 폴리우레탄의 원료인 폴리올을 같은 중량비율로 2등분하는 공정, 2등분된 폴리올 중에서 한쪽 폴리올에는 화학반응에 필요한 물을 혼합하는 공정, 2등분된 폴리올 중에서 다른 쪽 폴리올에는 숯을 첨가시켜 혼합 분쇄한 뒤 숯분말이 포함된 폴리올을 만드는 공정, 그리고 물이 혼합된 폴리올과 숯분말이 혼합된 폴리올을 이소시아네이트와 혼합부에서 혼합한 뒤 제2노즐을 통하여 하부금형의 폴리우레탄층으로 발포시켜 숯혼합폴리우레탄층이 성형되도록 한 공정으로 이루어진다.In order to achieve the above object, the present invention provides a process for forming a polyurethane layer by foaming a polyurethane in a lower mold, dividing a polyol, which is a raw material of polyurethane, into two parts by the same weight ratio, The process of mixing the water required for the reaction, the process of making the polyol containing the charcoal powder after mixing and grinding the charcoal to the other polyol of the second divided polyol, and the polyol mixed with the water and the polyol charcoal powder After mixing in the isocyanate and mixing section and foamed to the polyurethane layer of the lower mold through the second nozzle is made of a process for molding the charcoal mixed polyurethane layer.

The present invention has a process of mixing water and isocyanate in a polyol, which is a raw material of polyurethane, and then foaming the lower mold 1 through the first nozzle 2.

하부금형(1)은 사람이 앉을 수 있도록 시트의 윗면 형상으로 제작된 것이며 폴리우레탄이 발포되면 제1상부금형(4)을 닫아 폴리우레탄층(3)이 성형되도록 해준다.The lower mold 1 is manufactured in the shape of the upper surface of the seat for a person to sit on, and when the polyurethane is foamed, the first upper mold 4 is closed to allow the polyurethane layer 3 to be molded.

그리고 폴리우레탄층(3)이 형성되고 난 뒤 제1상부금형(4)을 들어내고 다음 공정으로 하부금형(1)을 이송시킨다. 다음 공정은 숯분말을 폴리우레탄에 포함시키는 공정이다.After the polyurethane layer 3 is formed, the first upper mold 4 is lifted and the lower mold 1 is transferred to the next process. The next step is to include the charcoal powder in the polyurethane.

폴리우레탄의 원료인 폴리올을 같은 중량비율로 2등분한 뒤 한쪽 폴리올은 화학반응에 필요한 물을 혼합해 주고 다른 쪽 폴리올은 숯을 혼합 분쇄시키는 공정을 갖는다.After dividing the polyol, which is a raw material of polyurethane, into two parts at the same weight ratio, one polyol is mixed with water for chemical reaction and the other polyol has a process of mixing and grinding charcoal.

그리고 폴리우레탄의 원료인 이소시아네이트와 숯분말이 혼합된 폴리올및 물이 혼합된 폴리올을 혼합부(5)에서 동시에 혼합한 뒤 제2노즐(6)을 통하여 하부금형(1)의 폴리우레탄층(3)으로 발포시키는 공정을 갖는다.And the polyurethane layer of the lower mold (1) through the second nozzle (6) after mixing the polyol mixed with isocyanate and charcoal powder and the polyol mixed with water at the same time in the mixing section (5) ) Is foamed.

폴리우레탄층(3)에 숯혼합폴리우레탄을 발포한 뒤 제2상부금형(8)을 닫아 숯혼합폴리우레탄층(7)이 성형되도록 해준다. 그리고 제2상부금형(8)을 열고 완성된 제품을 하부금형(1)에서 인출하면 본 발명의 시트가 만들어 진다.After the charcoal mixture polyurethane is foamed on the polyurethane layer 3, the second upper mold 8 is closed to allow the charcoal mixture polyurethane layer 7 to be molded. And opening the second upper mold (8) and withdrawing the finished product from the lower mold (1) is made of the sheet of the present invention.

본 발명의 시트는 일반 폴리우레탄층(3)의 표면에 숯혼합폴리우레탄층(7)을 이중으로 만들 수 있음으로 자동차 내부의 냄새를 제거시킬 수 있다. 그리고 숯에서 발생되는 음이온 및 원적외선에 의해 심신이 안정되고 공기가 정화되는 등의 효과가 있다.도 4는 본 발명 다른 실시예의 시트의 원료 혼합공정을 나타낸 블럭도 이다. 본 발명 다른 실시예는 숯분말을 폴리올에 혼합시키지 않고 이소시아네이트에 혼합시킨 것이며 나머지 공정은 위에서 언급한 것과 동일하다.본 발명 다른 실시예는 숯분말을 폴리우레탄에 포함시키는 공정으로써, 폴리우레탄의 원료인 이소시아네이트를 물과 비슷한 점도(15CPS) 및 온도(25℃)가 유지되도록 한 상태에서 숯분말을 자연스럽게 잘 섞는다. 숯은 흡착성이 강함으로 이소시아네이트가 저장된 탱크는 밀폐시키고 가급적 당일 사용될 분량만 혼합시켜 저장해 두는 것이 좋다.그리고 폴리우레탄의 원료인 물이 혼합된 폴리올과 이소시아네이트 혼합물을 혼합부(5)에서 동시에 혼합한 뒤 제2노즐(6)을 통하여 하부금형(1)의 폴리우레탄층(3)으로 발포시키면 숯이 포함된 시트가 완성된다.The seat of the present invention can remove the smell of the interior of the vehicle by being able to double the charcoal mixture polyurethane layer 7 on the surface of the general polyurethane layer (3). In addition, the body and body are stabilized by the anion and far infrared rays generated from charcoal, and the air is purified. FIG. 4 is a block diagram showing a raw material mixing process of the sheet according to another embodiment of the present invention. Another embodiment of the present invention is a mixture of charcoal powder in isocyanate without mixing in a polyol and the rest of the process is the same as mentioned above. Another embodiment of the present invention is a process for including a charcoal powder in polyurethane, a raw material of polyurethane The charcoal powder is naturally mixed well while phosphorus isocyanate is maintained at a viscosity (15 CPS) and temperature (25 ° C.) similar to water. Charcoal is highly adsorptive, so it is recommended to keep the isocyanate tank closed and store only the amount to be used on the day. When foamed into the polyurethane layer 3 of the lower mold 1 through the second nozzle 6, a sheet containing char is completed.

이상에서와 같이 본 발명에 따르면 폴리우레탄의 원료인 폴리올에 숯분말을 첨가시켜 우레탄을 발포함으로 숯 고유의 기능을 갖는 시트를 만들 수 있다.As described above, according to the present invention, by adding charcoal powder to a polyol which is a raw material of polyurethane, foaming urethane can make a sheet having a unique charcoal function.

폴리올의 화학반응에 필요한 물을 숯분말이 흡수하지 못하도록 폴리올을 2등분하여 한쪽에는 물을 혼합시키고 다른 쪽에는 숯분말을 혼합시킨 뒤 이들을 다시 합치기 때문에 폴리우레탄의 물성 변화 없는 시트를 제작할 수 있다. 그리고 내구성과 항균성 및 악취제거성을 갖는 시트를 제작할 수 있는 등의 효과가 있다.In order to prevent the charcoal powder from absorbing the water necessary for the chemical reaction of the polyol, the polyol is divided into two parts, water is mixed on one side, and charcoal powder is mixed on the other side, and then, these are combined again, thereby making a sheet without changing the physical properties of the polyurethane. And there is an effect such as to produce a sheet having durability and antibacterial and odor removal.
