Description
본 발명은 폴리프로필렌 섬유 부직포를 이용하여 자동차 루프 트림 (roof trim)을 제조하는 방법에 관한 것이다.The present invention relates to a method of making automotive roof trims using polypropylene fiber nonwovens.
보다 상세하게는, 본 발명은 기존의 폴리에스테르 부직포를 폴리프로필렌 섬유로 대체하고 이를 폴리올레핀계 필름 접착제 또는 폴리아마이드계 웹 상태의 필름을 사용하여 기재에 열용융 압착하는 자동차 루프 트림의 제조방법에 관한 것으로서, 상기 루프 트림은 기재와의 접착 방법이 간단하고 재활용할 수 있는 상태로 제조될 수 있어 자원의 재활용, 원가 절감 및 공정 단축 등에 매우 유리하다.More specifically, the present invention relates to a method for manufacturing a car roof trim by replacing the existing polyester nonwoven fabric with polypropylene fiber and hot melt pressing the substrate using a polyolefin-based film adhesive or a film of a polyamide-based web state. As the roof trim can be manufactured in a simple and recyclable state, it is very advantageous to recycle resources, reduce costs and shorten processes.
자동차는 외부 자극에 의한 충격을 완화하기 위하여 외장 패널 내에 루프 트림이라는 구조물을 가진다. 이러한 자동차 루프 트림은 기본적으로 기재, 표피재, 쿠션재 및 접착재 등으로 구성되어 있다.The vehicle has a structure called a roof trim in an exterior panel to mitigate the impact of external stimuli. The automotive roof trim is basically composed of a base material, a skin material, a cushion material and an adhesive material.
현재 주로 사용되는 루프 트림은 폴리에스테르 섬유로 만든 부직포, 변성 폴리아마이드 필름 그리고 웹(web) 및 골판지 구조의 크라프트 종이 (F-10)의 3층 구조로 이루어져 있다. 상기에서 표피재로 사용되는 부직포는 폴리에스테르 섬유 (3 데니어)에 각종 부가제로서 에틸렌비닐클로라이드 (ethylenevinyl chloride, EVCL) 및 폴리에틸렌테레프탈레이트 (polyethylene terephthalate, PET) 결합체 (binder), 난연제 및 대전방지제 등을 처리한 다음 그의 뒷면에 폴리에칠렌 파우더를 뿌려 핫 멜트 (hot melt) 필름과의 접착력을 강하게 하여 사용된다. 상기의 과정으로 제조한 루프 트림은 접착력을 강하게 하는 파우더를 사용하는 등으로 이를 재활용하는데 많은 어려움이 있었다.Currently used roof trim consists of a three-layer structure of nonwoven fabric made of polyester fiber, modified polyamide film, and web and corrugated kraft paper (F-10). The nonwoven fabric used as the skin material is ethylenevinyl chloride (EVCL), polyethylene terephthalate (PET) binder, flame retardant, antistatic agent, etc. as various additives to polyester fiber (3 denier). It is then used to strengthen the adhesion with the hot melt film by spraying a polystyrene powder on his back. Loop trim prepared by the above process has a lot of difficulties in recycling it by using a powder to strengthen the adhesion.
이외에도 지금까지 자동차 루프 트림으로 폴리프로필렌 (polypropylene, PP) 부직포를 사용한 예가 있으나, 이 때 폴리프로필렌 부직포는 폴리에틸렌테레프탈레이트 (PET)와 혼방한 타입이었고, 이를 기재와 접착하는 과정에 있어 폴리아마이드계 필름 및 웹을 사용함으로 인해 원가가 많이 들고 또 제조 공정 상에서 복잡한 문제점이 있었다.In addition, there is an example of using a polypropylene (PP) nonwoven fabric as an automotive roof trim, but at this time, the polypropylene nonwoven fabric was a type mixed with polyethylene terephthalate (PET), and a polyamide-based film in the process of bonding it to a substrate And due to the use of the web costs a lot and there was a complicated problem in the manufacturing process.
이에 본 발명자들은 제조 공정이 간편한 폴리프로필렌 섬유 부직포를 이용하는 자동차 루프 트림을 생산하기 위하여, 폴리프로필렌 섬유 부직포를 폴리올레핀계 필름 접착제 또는 폴리아마이드계 웹 상태의 필름을 사용하여 골판지 구조의 크라프트 종이판 (F-10), 레진펠트 경화판, 세미리기드 폴리우레탄 또는 폴리프로필렌 폼 등의 기재에 열용융 압착하고 일부 재활용도 가능한 자동차 루프 트림을 제조함으로써 본 발명을 완성하였다.In order to produce a car loop trim using a polypropylene fiber nonwoven fabric having a simple manufacturing process, the present inventors have made a polypropylene fiber nonwoven fabric using a polyolefin-based film adhesive or a film of a polyamide-based web state to form a kraft paper board having a corrugated structure (F). -10), the present invention was completed by manufacturing an automotive roof trim that can be hot melt pressed and partially recycled to a substrate such as a cured resin felt plate, a semi-rigid polyurethane, or a polypropylene foam.
본 발명은 제조 공정이 간편하고 일부 재활용도 할 수 있는 폴리프로필렌 섬유를 이용한 자동차 루프 트림을 제조하는 방법을 제공함에 그 목적이 있다.It is an object of the present invention to provide a method for manufacturing a car roof trim using polypropylene fibers which can be easily recycled and partially recycled.
상기 목적을 달성하기 위하여, 본 발명은 폴리프로필렌계 섬유 부직포를 폴리올레핀계 필름 접착제 또는 폴리아마이드계 웹 상태의 필름을 사용하여 기재에 열용융 압착한 자동차 루프 트림을 제조한다. 이 때 기재로는 골판지 구조의 크라프트 종이판 (F-10), 레진펠트 경화판 또는 세미리기드 폴리우레탄 등을 사용하고, 이외에도 폴리프로필렌이 포함된 3층 적층판 (버블쉬트) 또는 1-6 배 발포한 독립구조의 폴리프로필렌 폼 등을 사용하여 재활용이 가능한 자동차 루프 트림을 제조한다.In order to achieve the above object, the present invention manufactures a car roof trim of the polypropylene-based fiber nonwoven fabric by hot-melting pressing the substrate using a polyolefin-based film adhesive or a film of a polyamide-based web state. In this case, a corrugated kraft paper plate (F-10), a resin felt hardened plate, or a semi-rigid polyurethane is used as the base material, and in addition, a three-layer laminate (bubble sheet) containing polypropylene or 1-6 times Recyclable car roof trims are manufactured using foamed polypropylene foam, etc.
이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.
본 발명은 기존의 자동차 루프 트림에 적용되는 폴리에스테르 부직포를 폴리프로필렌 섬유로 대체한 자동차 루프 트림을 제공한다.The present invention provides a car roof trim in which a polyester nonwoven fabric applied to a conventional car roof trim is replaced with a polypropylene fiber.
본 발명은 폴리프로필렌 섬유로 중량 180 내지 220 g/m2(필름 및 폴리에틸렌 파우더를 처리한 경우 250 내지 290 g/m2)이고, 실의 굵기 1-5 데니어 (denier)의 섬유를 사용하며, 바람직하게는 2.5-3.5 데니어의 섬유를 사용한다. 상기 폴리프로필렌 섬유가 2.5 데니어 이하가 되면 섬유의 장력이 약하여 부직포를 제작하는 과정에 마모가 유발되고, 3.5 데니어 이상이 되면 섬유 표면의 촉감이 거칠어진다.The present invention uses a polypropylene fiber weight of 180 to 220 g / m 2 (250 to 290 g / m 2 when treated with film and polyethylene powder), using a fiber thickness of 1-5 denier (denier) of the yarn, Preferably, 2.5-3.5 denier fibers are used. When the polypropylene fiber is less than 2.5 denier, the tension of the fiber is weak, causing wear in the process of manufacturing the nonwoven fabric, and when more than 3.5 denier, the surface of the fiber becomes rough.
상기 폴리프로필렌 섬유는 다음과 같은 과정으로 제조한다.The polypropylene fiber is prepared by the following process.
본 발명은 폴리프로필렌 섬유를 일정하게 배열하기 위하여 소모기 (carding)를 이용하여 정련하고, 상기 원사의 밀도 편차를 줄이기 위하여 압축공기 및 기계적 혼합을 이용하여 균질화를 한 다음 와이어러 (wirer)가 있는 롤러 (roller)의 속도차로 소모 (carding)한다.The present invention is refined using carding to uniformly arrange the polypropylene fibers, homogenized by using compressed air and mechanical mixing to reduce the density variation of the yarn, and then there is a wirer Carding is caused by the speed difference of the roller.
구체적으로, 중량이 1-40 g/m2범위인 웹을 가로 세로로 교락시키면서 3 내지 19층으로 겹치도록 소모하고 30-45 호칭의 CON, RB, CSM, RBM, CBA 바늘 등을 사용하여 3 내지 7차에 걸쳐서 니들링 (needling)한다. 또한, 이외에도 후도 조정 및 중량 조절을 위하여 와인딩 (winding) 공정을 수행한다.Specifically, using a 30-45 nominal CON, RB, CSM, RBM, CBA needles and the like consumed so as to overlap 3 to 19 layers while interlacing the web having a weight in the range of 1-40 g / m 2 horizontally and vertically. Needed over the seventh order. In addition, a winding process is performed for post-adjustment and weight adjustment.
또한, 상기 폴리프로필렌 섬유는 표면의 열수축을 방지하고 균제도를 보완하기 위하여 후공정으로서 다음과 같이 화학 처리를 한다. 구체적으로 접착제로서 일정 크기의 롤을 이용하여 약품의 처리량 등을 조절하면서 아크릴 폼형태의 표면 백처리를 하는데, 이 때 상기 처리 약품의 건조와 열안정을 위하여 폴리프로필렌 섬유는 80 내지 120℃ 온도에서 원단 속도 2-6 m/분으로 건조로를 거치는 것이 바람직하다. 상기 과정에서 원단의 두께를 조절하면서 롤링 및 냉각 과정을 수행할 수 있다.In addition, the polypropylene fiber is subjected to a chemical treatment as follows as a post-process in order to prevent thermal shrinkage of the surface and to supplement the uniformity.

상기에서 살펴 본 바와 같이. 본 발명의 루프 트림은 폴리프로필렌 섬유 부직포를 폴리올레핀계 필름 접착제를 사용하여 기재에 압착함으로 재료의 동질성으로 인해 접착 강도가 강해지고 제조 원가가 절감된다. 또한, 실시예 3 의 방법과 같이 폴리프로필렌이 포함된 3층 적층판 (버블쉬트) 또는 1-6배 발포한 독립구조의 폴리프로필렌 폼에 폴리프로필렌계 쉬트를 대어 압출기 다이를 통과시키면서 폴리프로필렌계 섬유 부직포를 접착시키는 경우 재료의 구조상 재활용이 가능하므로 유용하다. 이외에도 상기 폴리프로필렌 섬유 루프 트림은 무극성을 띠어 오염이 적고 자재 관리가 편리하며 인장 강도 및 신장 탄성율이 높아 성형성이 우수하다.As discussed above. The loop trim of the present invention compresses the polypropylene fiber nonwoven fabric to the substrate using a polyolefin-based film adhesive, thereby increasing the adhesive strength and reducing the manufacturing cost due to the homogeneity of the materials. In addition, as in the method of Example 3, a polypropylene-based fiber was passed through an extruder die by applying a polypropylene sheet to a three-layer laminate (bubble sheet) containing polypropylene or an independent polypropylene foam foamed 1-6 times. It is useful when the nonwoven fabric is bonded because it is possible to recycle the material structurally. In addition, the polypropylene fiber loop trim is non-polar, so there is little contamination, convenient material management, high tensile strength, high elastic modulus, and excellent moldability.
