본 발명은 자동차용 성형기재에 관한 것으로서, 보다 구체적으로는 견면을 주재료로 하며 향상된 흡음성능 및 중량감소효과를 가지면서 환경친화적인 자동차용 플로우 카페트 기재 및 그 제조방법에 관한 것이다.The present invention relates to a molding material for automobiles, and more particularly, to an environmentally friendly automobile flow carpet substrate and a method for manufacturing the same, with the main material as the main material and having improved sound absorption performance and weight reduction effect.
자동차용 플로우 카페트 기재는 자동차 하부에 부착되어 자동차의 주행시에 발생하는 소음을 차단하는 한편 충격을 흡수하여 안락한 승차감을 제공하는 것이 요구된다.The flow carpet substrate for automobiles is required to be attached to the lower part of the vehicle to block noise generated when the vehicle is driven, while absorbing shock to provide a comfortable ride.
종래에 사용되고 있는 플로우카페트용 기재는 주로 페놀파우더를 바인더로 사용하고 있는 레진펠트 및 잡사를 원료로 니들펀칭한 니들펠트가 사용되고 있다. 그러나, 기존의 자동차용 플로우카페트용 기재들 중에서 레진펠트는 분진 및 냄새가 심하므로 인체에 유해하며, 그 제조공정 중에 사용되는 페놀파우더로 인해 환경오염 문제가 발생하며, 니들 펠트의 경우에도 분진이 발생하는 문제점을 안고있다.As a substrate for flow carpets used in the related art, resin felts using phenolic powder as binders and needle felts using needle punching as raw materials are used. However, the resin felt is harmful to the human body because of the dust and odor among the existing substrates for the flow carpet for automobiles, environmental pollution problem occurs due to the phenol powder used during the manufacturing process, even in the case of needle felt I have a problem that occurs.
또한, 기존의 자동차용 플로우카페트 기재는 기재 하부에 핫멜트 필름이 부착되고, 그 하부에는 승차감을 개선하기 위한 헤비레이어(Heavy Layer)라는 제진재가 부착되며, 그 하부에 레진펠트가 부착되거나, 니들펠트를 사용하는 경우에는 니들펠트 중간부위에 헤비레이어층을 삽입하여 승차감 개선 및 차음성능을 개선하게 되어 있다. 이와 같은 구조의 자동차용 플로우카페트는 자체 무게가 상당하여 차량의 중량을 지나치게 높아지게 하고, 그 결과로서 이를 적용한 자동차의 연료소모율을 증대시키는 등의 문제를 초래하게 된다.In addition, the conventional automotive carpet carpet is a hot melt film is attached to the lower portion of the base material, a heavy layer (Heavy Layer) vibration damping material is attached to the lower portion, the resin felt is attached to the lower portion, When the felt is used, a heavy layer layer is inserted in the middle of the needle felt to improve riding comfort and sound insulation performance. The flow carpet for automobiles having such a structure has a considerable weight so that the weight of the vehicle is excessively high, and as a result, a problem such as increasing the fuel consumption rate of the vehicle to which it is applied is caused.
따라서 본 발명은 상기한 바와 같은 선행기술의 제반 문제점을 해소할 수 있는 새로운 플로우카페트 기재를 제공하는 것을 기술적 과제로 한다.Therefore, the present invention is to provide a new flow carpet substrate that can solve all the problems of the prior art as described above as a technical problem.
상기한 과제를 해결하기 위하여 본 발명자는 물질의 밀도에 따라 음파의 속도 및 굴절율이 변화된다는 물리적 이론에 착안하여 밀도차이를 준 폴리에스테르기재를 이용한 플로우카페트 기재를 사용하면 음원이 반사되고 굴절되는 효과가 생겨나서 헤비레이어의 사용 없이 높은 흡차음성능을 달성할 수 있고, 또한 헤비레이어의 사용 배제에 따른 차량의 중량 감소도 달성할 수 있고 그 결과 연비개선에도 효과가 있을 뿐만 아니라 폴리에스테르 기재의 특성상 분진발생, 악취, 페놀파우더 등의 위생, 환경문제를 유발하지 않는다는 사실을 알게 되어 본 발명을 완성하게 된 것이다.In order to solve the above problems, the inventors pay attention to the physical theory that the speed and refractive index of sound waves change according to the density of materials, and the effect that the sound source is reflected and refracted is when using a flow carpet substrate using a polyester substrate having a density difference. It is possible to achieve high sound absorbing and insulating performance without using heavy layer, and also to reduce the weight of the vehicle by eliminating the use of heavy layer. The present invention is completed by knowing that dust generation, odor, hygiene of phenol powder, and the like does not cause environmental problems.

이하, 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 자동차용 플로우카페트 기재는 폴리에스터 바인더파이버와 폴리에스터 매트릭스파이버로 구성된 견면과, 상기 견면의 양면 또는 일면에 열처리된 피막이 형성된 것으로 구성된다.The flow carpet substrate for automobiles of the present invention is composed of a surface formed of a polyester binder fiber and a polyester matrix fiber, and a heat-treated film formed on both surfaces or one surface of the surface.
상기 기재의 제조를 위해서 융점이 80∼120℃이고 섬도가 2∼4 데니어인 폴리에스터 바인더파이버 30∼50%, 섬도가 3∼15 데니어인 매트릭스파이버 50∼70%로 구성된 것을 사용하는 것이 바람직하며 상기 바인더파이버와 매트릭스 파이버를 카딩하여 웹을 형성하고 이 웹을 예열처리수단에서 예열하여 용융열처리수단으로 공급되는 웹적층물의 섬유가 흐트러지지 않고 균일하게 배열되도록 한다. 웹적층물은 용융열처리수단에서 바인더 파이버의 용융온도 이상과 매트릭스파이버의 용융온도 이하의 온도(100∼150℃)에서 용융열처리되며 이후에 히팅프레스와 같은 가열압착수단을 통과하면서 필요 강도 및 두께로 융착되어 목적하는 견면으로 준비되는 것이 바람직하다.For the production of the base material, it is preferable to use a composition composed of 30 to 50% of polyester binder fiber having a melting point of 80 to 120 ° C. and 2 to 4 denier, and 50 to 70% of matrix fiber having a fineness of 3 to 15 denier. The binder fiber and the matrix fiber are carded to form a web, and the web is preheated in the preheating means so that the fibers of the web stack supplied to the fusion heat treatment means are arranged uniformly without being disturbed. The web laminate is melt heat treated at a temperature (100 to 150 ° C.) above the melting temperature of the binder fiber and below the melting temperature of the matrix fiber in the melt heat treatment means, and then passes through a heat pressing means such as a heating press to a required strength and thickness. It is preferable to be fused and prepared to a desired plush.
본 발명에서 사용되는 폴리에스터 매트릭스 파이버는 성형후의 외관과 표면강도를 개선하는 역할 및 흡음역할을 하는 것으로서 소정의 비율로 혼합된 파이버를 사용하되 3∼15데니어인 것을 사용하는 것이 바람직하며 3∼15 데니아의 매트릭스섬유를 함유한 기재에서는 15%이상의 흡차음개선효과를 발현하게 됨과 동시에 표면강도를 강화시킴으로써 장착후의 승차감개선에 큰 효과를 주게된다. 상기의 폴리에스테르 바인더 섬유의 경우에는 단면의 형태가 시스/코어(Sheath/Core)형태를 가진 이중구조의 파이버를 사용하여 후의 열융착공정에서 폴리에스테르 바인더 섬유의 일부가 용융되어 폴리에스테르 매트릭스 섬유와 결합하게 되는 것이다.Polyester matrix fiber used in the present invention is to improve the appearance and surface strength after molding, and to act as a sound absorption, but it is preferable to use a mixture of 3 to 15 denier, and use 3 to 15 denier in a predetermined ratio. In the base material containing Denia's matrix fiber, the sound absorbing and improving sound effect of 15% or more is expressed, and the surface strength is enhanced to give a great effect on improving the riding comfort after mounting. In the case of the polyester binder fiber, a part of the polyester binder fiber is melted in a subsequent heat fusion process using a double-structured fiber having a sheath / core shape in the cross-section, and thus a polyester matrix fiber Will be combined.
본 발명에서의 자동차용 플로우카페트 기재는 기존의 견면공정에서 열오븐기이후에 핫프레스롤러(설정온도:150∼250℃)가 설치된 공정을 통과하게 된다. 견면은 열융착이후 냉각롤러를 통과하면서 표면을 냉각시키게 되는데 냉각롤러를 사용하는 이유는 열오븐을 통과한 견면을 바로 핫프레스 롤러로 이송하게되면, 표면에 남아있는 잔열에 의해 견면이 롤러에 달라붙는 현상이 발생하게 되기 때문에 우선적으로 표면을 냉각하는 것이다.The flow carpet substrate for automobiles in the present invention passes through a process in which a hot press roller (set temperature: 150 to 250 ° C.) is installed after a heat oven in a conventional plush process. After the heat welding, the surface passes through the cooling roller to cool the surface. The reason for using the cooling roller is to transfer the surface passed through the hot oven to the hot press roller, and the surface is changed by the residual heat remaining on the surface. Since sticking occurs, the surface is first cooled.
상기의 냉각된 견면은 핫프레스롤러(표면온도 : 150∼250℃)사이로 통과되면서 제품의 양면 또는 일면이 열처리되는데 이때 상하2개로 구성된 롤러가 1단 내지 3단으로 형성된 핫프레스롤러를 통과되면서 견면의 구성파이버중 핫프레스롤러와 인접한 부분에 위치한 견면의 바인더섬유가 용융, 압착되어 열융착견면의 내부층과 밀도가 다른 피막을 형성하게 되고, 이후 다시 한번 냉각기를 통과하면서 제품이 일정두께로 고정되게 된다.The cooled plush is passed between hot press rollers (surface temperature: 150 to 250 ° C), and both surfaces or one surface of the product are heat treated. At this time, the upper and lower rollers pass through a hot press roller formed of one to three stages. The binder fiber of the plush located near the hot press roller of the constituent fiber is melted and compressed to form a film having a different density from the inner layer of the heat-sealed dog face, and then the product is fixed to a certain thickness while passing through the cooler Will be.
특히, 일면만 열처리하는 경우에는 양면으로 피막을 입힌 경우 대비 흡차음성능이 다소 저하되는 경향이 있을 것으로 보이나, 피막이 형성된 부위를 카페트와 접하는 쪽으로 하고, 피막이 형성되지 않은 면을 차의 바닥쪽으로 장착하게 되면피막이 형성되지 않은 면과 차바닥과의 슬립 및 이에 따른 외부소음이 투과됨으로써 발생하는 소음을 방지함으로써 오히려 흡차음성능이 개선되는 효과를 볼 수 있다.In particular, when heat-treating only one side, the sound absorbing and sound-proofing performance tends to be slightly lower than when the film is coated on both sides, but the portion where the film is formed is in contact with the carpet, and the surface where the film is not formed is mounted on the bottom of the car. When the surface is not formed and the slip between the bottom of the car and thus the noise generated by the external noise is transmitted through the sound absorbing and sound insulation performance can be seen rather improved.
피막의 두께는 제품의 두께와 상관없이 0.1∼5mm정도가 바람직하며 5mm이상이 되면 기재자체가 딱딱해서 장착작업이 어렵게 되는 문제가 발생하게 되며, 0.1mm미만이 되면 양호한 흡차음효과를 기대할 수 없게 된다. 따라서 기재의 양면 또는 한쪽면에 피막을 형성하게 함으로써 기존의 피막이 없는 폴리에스터 기재와 대비할 때 3∼6 데니아의 매트릭스섬유를 함유한 기재에서는 5∼10%의 흡차음 개선효과를 얻을 수 있고, 6∼15 데니아의 매트릭스섬유를 함유한 기재에서는 15%이상의 흡차음개선효과를 발현하게 됨과 동시에 표면강도를 강화시킴으로써 장착후의 승차감개선에 큰 효과를 주게된다.Regardless of the thickness of the product, the thickness of the film is preferably about 0.1 to 5 mm, and when the thickness is 5 mm or more, the substrate itself becomes hard, so that the mounting work becomes difficult. do. Therefore, by forming a film on both sides or one side of the base material, 5 to 10% of the sound absorbing and sound-improving effect can be obtained in a base material containing 3 to 6 denier matrix fibers as compared to a polyester base material having no film. Substrate containing -15 denier matrix fibers exhibits 15% or more of sound absorbing and improving sound effect, and at the same time, the surface strength is enhanced to give a great effect on improving riding comfort after installation.
또한 견면을 구성하는 파이버를 다양한 섬도별로 혼합시키는 경우에는 특정범위의 주파수뿐만 아니라 광대역의 주파수 범위의 흡차음효과를 얻을수 있으며 자동차에서 발생되는 소음의 종류에 따라 구성섬유의 섬도를 조절하여 특정분야에 필요한 흡차음효과를 극대화시킬수 있다. 또한 사용하는 핫프레스롤러의 표면에 격자무늬를 새겨 넣음으로써, 표면 외관상 수려함과 동시에 고주파에서 저주파에 이르는 광대역의 음파를 흡차음할수 있다. In addition, when the fibers constituting the plush are mixed according to various fineness, the sound absorbing and sounding effect can be obtained not only in a specific range of frequencies but also in a wide range of frequencies. It can maximize the sound absorbing and insulating effect required. In addition, by imposing a lattice pattern on the surface of the hot press roller to be used, it is possible to absorb and absorb a wide range of sound waves from high frequency to low frequency at the same time as the surface appearance is beautiful.
기존의 기재들의 경우 위생, 환경문제와 아울러 흡음성을 개선하기 위해 단위면적당 중량을 올림으로써, 흡음성은 개선이 되지만, 차량의 중량이 올라감으로 인한 연비상승등의 문제를 갖고 있었다.In the case of the existing substrates by increasing the weight per unit area in order to improve sound absorbency as well as hygiene and environmental problems, sound absorption is improved, but there was a problem such as fuel efficiency increase due to the increase in the weight of the vehicle.
그러나, 본 발명에서 소개하는 기재의 경우, 100% 폴리에스터를 사용함으로써 분진발생, 악취, 페놀파우더 등의 위생, 환경문제가 해결됨과 동시에 기재 양면에 기재와 밀도가 다른 피막을 형성함에 따른 음원의 반사작용으로 인하여 기존의 피막이 없는 폴리에스터 기재와 대비할 때 3∼6데니아의 매트릭스섬유를 함유한 기재에서는 5∼10%의 흡차음 개선효과를, 6∼15데니아의 매트릭스섬유를 함유한 기재에서는 15%이상의 흡차음개선효과를 발현하게 됨으로써 기존의 레진펠트나 니들펠트등에 비해 본 기재의 경우에는 카페트 하부에 핫멜트 필름이 부착되나, 그 하부에 바로 폴리에스터 층이 부착됨으로써, 헤비레이어를 삭제하는 효과가 있고, 아울러 기존 기재대비 60~70%의 중량만으로도 흡차음성능이 동등이상으로 발현하게 됨으로써, 차량의 중량저감 및 이로 인한 연비개선효과를 얻을 수 있다.However, in the case of the substrate introduced in the present invention, by using 100% polyester, the hygienic and environmental problems such as dust generation, odor, phenol powder, etc. are solved, and at the same time, the film is formed on both sides of the substrate with different density from the substrate. Due to the reflex action, 5 to 10% of sound absorption and sound absorption is improved in substrates containing 3 to 6 denier matrix fibers compared to polyester films without conventional coating, and 15 to 6 15 denier matrix fibers. By expressing the sound absorbing and improving sound effect of more than%, in the case of the present substrate, the hot melt film is attached to the lower part of the carpet compared to the existing resin felt or needle felt, but the polyester layer is directly attached to the lower part, thereby eliminating the heavy layer. In addition, the sound-absorbing sound insulation performance is expressed as equal or more even with only 60 to 70% by weight of the existing substrate, the weight of the vehicle It is possible to obtain the sense and resulting fuel economy improvements.
일면만 열처리하여 피막을 형성하는 경우에는 피막이 형성된 부위를 카페트와 접하는 쪽으로 하고, 피막이 형성되지 않은 면을 차의 바닥쪽으로 장착하게 되면 피막이 형성되지 않은 면과 차바닥과의 슬립 및 이에 따른 외부소음이 투과됨으로써 발생하는 소음을 흡수함으로써 흡차음성능이 개선된다. 또한 견면의 구성파이버 섬도의 다양한 선택으로 광대역의 주파수범위에 대한 흡차음효과를 얻을 수 있으며, 동일 종류의 섬유를 이용한 기재의 제조로 인한 공정의 간소화 및 생산성의 제고의 효과도 얻을 수 있다.If only one surface is heat-treated to form a film, the area where the film is formed is in contact with the carpet, and if the surface where the film is not formed is mounted toward the bottom of the car, slip between the surface where the film is not formed and the floor of the car and the resulting external noise Sound absorption and sound insulation performance is improved by absorbing the noise generated by the transmission. In addition, it is possible to obtain the sound absorbing and sound-proofing effect on the wide frequency range through various selections of the constituent fiber fineness of the plush, and also to simplify the process and improve the productivity by manufacturing the substrate using the same type of fiber.
