Description
본 발명은 저탄성 고밀도의 폴리올에 경화제(MDI)를 첨가 혼합시켜 베개를 비롯하여 쿠션·방석·등받이 등과 같은 폴리우레탄 쿠션제품을 제조하도록 하는 방법에 관한 것이다.The present invention relates to a method for producing polyurethane cushioning products such as pillows, cushions, cushions, backrests, etc. by adding and mixing a curing agent (MDI) to a low elastic high density polyol.
이를 좀 더 상세히 설명하면, 폴리올(Polyol)에 경화제인 MDI(Diphenyl Methane Diisocyanate)를 정량계량펌프에 의해 일정한 비율(량)로 믹싱헤드에 공급할 수 있도록 하고, 믹싱헤드를 통하여 공급되는 MDI와 폴리올을 히팅수단에 구비된 성형틀에 주입하여 일정한 시간동안 방치하여 성형시키며, 성형틀에서 성형된 성형물을 인출하여 밀폐열실에서 소정의 시간동안 건조시켜 주도록 하는 폴리우레탄 쿠션제품의 제조방법에 관한 것이다.In more detail, it is possible to supply MDI (Diphenyl Methane Diisocyanate), which is a curing agent to polyol, to the mixing head in a fixed ratio (quantity) by a quantitative metering pump, and to supply MDI and polyol supplied through the mixing head. The present invention relates to a method for manufacturing a polyurethane cushion product, which is injected into a molding mold provided in a heating means and left for a predetermined time to be molded, and withdraws the molded product from the molding mold to be dried in a closed heat chamber for a predetermined time.
일반적으로 사용되고 있는 베개와 같은 쿠션제품은 주머니의 내부에 솜을 비롯하여 스폰지 등 을 충진시켜 일정한 높이로 형성하여서 된 본체의 외부에 외피를 씌워서 된 것이 널리 알려져 있는데, 이와 같은 베개와 같은 종래의 쿠션제품은 높이가 일정하게 되어 있으므로 사용자의 신체조건과 특성에 맞도록 하여 사용할 수 없는 문제가 있었고, 탄력성이 강하여 쉽게 변형되거나 또는 탄력성이 너무 약하여 변형이 이루어지지 않아 사용자의 신체조건 특히 두부의 무게와 크기 및 경추 등에 적합하도록 제조할 수 없는 문제가 있었다.Cushion products, such as pillows, which are generally used, are widely known by covering the outer surface of a body formed by filling a cotton, a sponge, and the like into a pocket to a certain height, and a conventional cushion product such as a pillow. Since the height is constant, there is a problem that can not be used to match the user's physical conditions and characteristics, and the elasticity is easily deformed or the elasticity is too weak, the deformation is not made because the user's physical condition, especially the weight and size of the head And there was a problem that can not be manufactured to fit the cervical spine and the like.
이러한 문제를 해소할 수 있도록 하기 위하여 제안된 것으로서는 국내 실용신안 등록 제 168645호 "베개"와 국내 실용신안 등록 제 178642호 "베개"가 알려져 있다.As a proposal to solve such a problem, domestic utility model registration No. 168645 "pillow" and domestic utility model registration No. 178642 "pillow" are known.
전자는 소정의 높이와 폭을 갖는 사각형몸체의 내부에 경질의 탄성부재 또는 솜, 스폰지와 같은 연질의 탄성부재를 충진시키고, 사각형몸체의 중간부에 중간막을 형성하여서 된 것이다. 그러나, 이와 같이 형성된 종래의 베개는 두부를 받쳐주는 중간막이 너무 얇게 형성되어 있으므로 두부를 충분하게 받쳐주지 못하게 되는 문제가 있었고, 그로 인하여 목뼈(경부)가 수평상태를 이루지 못하고 과도하게 상측으로 만곡 변형되면서 경추가 손상되는 문제가 있었다.The former is made by filling a rigid elastic member such as a hard elastic member or a cotton or sponge, inside the rectangular body having a predetermined height and width, and forming an intermediate film in the middle of the rectangular body. However, the conventional pillow formed as described above has a problem that the intermediate film supporting the head is formed so thin that the head cannot be sufficiently supported, and thus the neck bone (neck) does not form a horizontal state and is excessively curved upward. The cervical spine was damaged.
또한, 후자는 베개케이스의 내부를 별도의 천(직물)에 의해 중앙부에서부터양측으로 높이가 낮은 경추 및 후주지지부, 경사면으로 되는 뒤척임이행부, 높이가 높은 뒤척임대응부로 각각 형성하여 각 내부에는 심층진재를 내장시키되, 베개의 정면을 내측으로 만곡되게 형성하여서 된 것이다. 그러나, 이와 같이 형성된 종래의 베개는 베개케이스의 내부에 내장된 심층진재가 면으로 형성되어 있으므로 사용자의 두부와 경추의 조건에 맞게 변형되지 못하여 사용에 불편함이 있었다. 또한 바로 누웠을 때에 경추와 두부를 받쳐주는 경추지지부와 후두지지부가 동일한 높이를 유지하고 있고 측면으로 누울 때에 경추와 후두를 받쳐주는 뒤척임대행부도 동일한 높이(수평)로 되어 있으므로 경추지지부 또는 뒤척임대행부의 전반부가 경추를 용이하게 받쳐 지지해주지 못하게 되고, 그로 인하여 경추가 무리하게 변형되어 통증을 유발시키는 문제가 있었다.In addition, the latter is formed by a separate fabric (fabric) from the center to both sides of the cervical spine and the posterior support of the lower height, the reclining transition part to be inclined surface, and the high rearward responsive part, respectively. The built-in, but the front of the pillow was formed to be curved. However, the conventional pillow formed as described above has been inconvenient to use because it can not be deformed to fit the condition of the head and cervical spine of the user because the deep-intrinsic dust is formed in the interior of the pillow case. In addition, the cervical support and the laryngeal support that support the cervical spine and head when lying down are maintained at the same height, and the posterior vertebral support that supports the cervical spine and larynx when lying on the side is the same height (horizontal), so Is not able to easily support the cervical spine, thereby causing the cervical strain is excessively deformed, causing pain.

본 발명의 상기한 목적과 특징은 첨부도면에 의거한 다음의 상세한 설명에의해 더욱 명확하게 이해할 수 있을 것이다.The above objects and features of the present invention will be more clearly understood by the following detailed description based on the accompanying drawings.
첨부도면 도1은 폴리우레탄 쿠션제품의 제조방법의 공정을 보인 계통도이고, 도 2a 및 도 2b는 본 발명에 의해 제조되는 폴리우레탄베개(10)·(10-1)를 보인 예시도이다.Figure 1 is a schematic diagram showing a process of manufacturing a polyurethane cushion product, Figures 2a and 2b is an exemplary view showing a polyurethane pillow 10, (10-1) produced by the present invention.
MDI탱트(1)에는 주재료로서 통상의 MDI(Diphenyl Methane Diisocyanate)을 충진시켜 주고, 폴리올탱크(2)에는 통상의 폴리올(Polyol)을 충진시켜 준다.The MDI tank 1 is filled with a conventional MDI (Diphenyl Methane Diisocyanate) as a main material, and the polyol tank 2 is filled with a conventional polyol.
MDI탱트(1)와 폴리올탱크(2)에 충진된 MDI와 폴리올은 정량계량펌프(3)와 믹싱헤드(4)로 구성되는 주입발포기에 의해 성형틀(5)에 주입시켜 주게 된다.MDI and polyol filled in the MDI tank (1) and the polyol tank (2) is injected into the mold 5 by an injection foamer composed of a metering pump (3) and the mixing head (4).
회전수를 조절할 수 있도록 되어 있는 정량계량펌프(3)는 MDI탱트(1)와 폴리올탱크(2)에 충진된 MDI와 폴리올을 믹싱헤드(4)로 공급시켜주게 되는데, 믹싱헤드(4)를 경유하여 MDI와 폴리올을 MDI탱트(1)와 폴리올탱크(2)로 되돌려 순환시켜주는 과정을 지속적으로 실시하여 MDI와 폴리올이 응고와 같이 변화되는 것을 방지하게 되고, 기계적인 변속기를 사용하거나 전기적인 인버터(Inverter)를 사용하여 회전수를 조절하여 MDI와 폴리올의 공급량을 조절할 수 있게 된다.The metering metering pump 3, which is capable of adjusting the rotation speed, supplies MDI and polyols filled in the MDI tank 1 and the polyol tank 2 to the mixing head 4. Through the process of circulating the MDI and polyol back to the MDI tank (1) and the polyol tank (2) by circulating, it prevents the MDI and polyol from changing like solidification, and uses a mechanical transmission or electrical By using an inverter (Inverter) by controlling the number of revolutions it is possible to control the supply amount of MDI and polyol.
이러한, 정량계량펌프(3)의 작동원리는 기히 공지된 기술사상이므로 보다 구체적인 설명은 생략하기로 한다.Since the operation principle of the quantitative metering pump 3 is well known in the art, a detailed description thereof will be omitted.
특히, 정량계량펌프(3)는 MDI와 폴리올의 공급량을 조절하여 공급하게 되는데, 예컨데 믹싱헤드(4)를 조작하여 MDI와 폴리올을 공급 토출시킬 때에 MDI가 공급되는 공급량과 폴리올이 공급되는 공급량을 적절하게 조정하여 제조되는 폴리우레탄베개의 탄성력을 조절할 수 있게 되는데, 폴리올의 공급량을 1초당 100g으로하였을 때에 경화제인 MDI가 30~45g 공급되어지도록 한다.In particular, the metering pump 3 is supplied by adjusting the supply amount of the MDI and polyol, for example, when the mixing head 4 is operated to supply and discharge the MDI and polyol, the supply amount of the MDI and the supply amount of the polyol are supplied. It is possible to adjust the elastic force of the polyurethane pillow prepared by adjusting appropriately, when the supply amount of the polyol is 100g per second so that 30 ~ 45g of MDI which is a curing agent is supplied.
이와 같이 폴리올을 기준으로 경화제인 MDI의 공급량을 조정하여 줌으로써 성형 제조되는 폴리우레탄 쿠션제품의 특성(경도)을 변화시켜 줄 수 있게 되며, 다음 표와 같은 특성을 얻을 수 있게 된다.Thus, by adjusting the supply amount of the curing agent MDI based on the polyol, it is possible to change the characteristics (hardness) of the polyurethane cushioning product to be molded and obtain the characteristics shown in the following table.
표 1.Table 1.
상기 표 1에서 확인되는 바와 같이 폴리올을 기준으로 하여 첨가되는 MDI의 공급량에 따라 제품의 특성을 다양하게 변화시킬 수 있게 된다.As can be seen in Table 1, the characteristics of the product can be variously changed according to the amount of MDI added based on the polyol.
상기 정량계량펌프(3)를 통해서 공급되는 MDI와 폴리올을 믹싱헤드(4)를 기히 설정되어 있는 시간동안 작동시켜 기히 설정되어 있는 량만큼을 성형틀(5)에 충진시켜 준다.The MDI and the polyol supplied through the metering pump 3 are operated for a predetermined time for the mixing head 4 to fill the mold 5 with a predetermined amount.
성형틀(5)은 본체에서 두껑을 개폐할 수 있도록 되어 있고, 본체와 두껑의 내부에는 발포를 빠르게 진행시킬 수 있도록 하기 위하여 히팅수단(5-1)을 구비하였다. 성형틀(5)은 히팅수단(5-1)에 의해 45~70℃로 유지시켜 주는 것이 바람직하고, MDI와 폴리올을 혼합하여 충진시킨 상태에서 3~ 10분간 방치하여 발포가 충분히 진행되어지도록 하는 것이 바람직한데, 발포성형시간이 짧게 하게 되면 발포가 충분히 이루어지지 않고 성형이 불량하게 이루어지게 되고, 발포성형시간을 길게 유지시키면 성형을 완전하게 이룰 수 있으나 생산성이 떨어지게 된다.Molding frame 5 is to open and close the lid in the body, and the heating means (5-1) is provided in the interior of the body and the lid so as to quickly advance the foam. Molding mold (5) is preferably maintained at 45 ~ 70 ℃ by the heating means (5-1), the mixture is allowed to stand for 3 to 10 minutes in a mixed state filled with MDI and polyol to allow the foaming to proceed sufficiently If the foaming time is short, it is preferable that the foaming is not made sufficiently and the molding is made poor, and if the foaming time is kept long, the molding can be completed completely, but the productivity is reduced.
상기와 같이 성형틀(5)에서 발포 및 성형이 완성된 성형품(7)을 인출하여 밀폐열실(6)에서 건조시켜준다. 밀폐열실(6)의 온도는 60~90℃로 너무 높지 않게 유지시켜 성형품(7)이 변형되는 것을 방지 할 수 있도록 하고, 60분 내지 180분간 방치하여 충분히 건조되어지도록 한다.As described above, the molded article 7 having completed the foaming and molding in the molding die 5 is taken out and dried in the sealed heat chamber 6. The temperature of the enclosed heat chamber 6 is maintained so as not to be too high at 60 ~ 90 ℃ to prevent the molded article 7 from being deformed, and allowed to dry for 60 minutes to 180 minutes.
건조를 완료한 후에 건조된 성형품(7)을 밀폐열실(6)에서 인출함으로써 도 2a 및 도 2b에 도시된 바와 같은 폴리우레탄베개(10)·(10-1)를 얻을 수 있게 된다.After completion of drying, the dried molded article 7 is taken out of the closed heat chamber 6 to obtain the polyurethane pillow 10 · 10-1 as shown in Figs. 2A and 2B.
본 발명에 따른 폴리우레탄 쿠션제품의 제조방법은 베개를 제조하는 다음의 실시예에 의하여 더욱 명확하게 이해 할 수 있으며, 다음의 실시예에 의해 본 발명의 범위가 한정(축소)되지 않음을 밝혀둔다.The method for producing a polyurethane cushion product according to the present invention can be more clearly understood by the following examples of preparing pillows, and the scope of the present invention is not limited (reduced) by the following examples. .
