Vehicle interior using natural fibers according to the present invention, the high rigidity
폼(100)은 흡음과 차음 그리고 성형성이 우수한 재질을 이용한다. 이러한 재질로는 예시적으로, 폴리우레탄(PU)으로 제조된 레이어를 이용할 수 있다.The
폴리우레탄은 기본적인 소재 구성으로 MDI + 폴리올(PPG)+ 촉매 외(etc.) 등으로 구성되며, 각 나라별 그리고 각 제조업체에 따라 다양한 방법으로 여러 용도에 맞게 제작된다. 그리고 생산방식에 있어서도 배치(Batch) 발포방식(Block)과 연속발포방식의 두 가지가 있다. 이러한 폴리우레탄으로는 연속발포방식을 취하고 있는 (주)세림TTC(www.serimttc.com)에서 제조된 제품을 이용하는 것이 바람직하다.Polyurethane is composed of MDI + polyol (PPG) + catalyst (etc.) as a basic material composition, and is manufactured for various purposes in various ways according to each country and each manufacturer. In addition, there are two types of production methods, batch foaming and continuous foaming. As such a polyurethane, it is preferable to use a product manufactured by Serim TTC (www.serimttc.com) taking a continuous foaming method.
이러한 상기 폴리우레탄은 제품명 PTSF(Polyurethane thermoformable semi-rigid foam), 즉 열성형이 가능한 반경질 폼 제품으로서 건식과 습식용으로 구분된다. 특히, 건식제품의 특징은 열성형이 가능한 코어 온도가 180∼ 190℃ 로서 성형 후 형상변형이 없는 것이 특징이며, 습식제품의 경우는 130∼150℃의 저온에서도 성형이 가능하다. 이들 제품의 특징으로는 성형 후 형상변형이 없을 뿐만 아니라 복잡한 형상제품에 대한 디자인 성형성이 우수하다. 그리고, 성형 후 치수안정성이 우수하며, 제품의 중량저감 및 N.V.H(흡음 기능성)에 있어서 탁월한 효과가 있다.
The polyurethane is a product name PTSF (Polyurethane thermoformable semi-rigid foam), that is, a thermoformable semi-rigid foam product is divided into dry and wet use. In particular, the dry product is characterized in that the core temperature is 180 to 190 ° C that can be thermoformed, there is no shape deformation after molding, in the case of wet products can be molded at a low temperature of 130 to 150 ° C. The features of these products are not only shape deformation after molding but also excellent design moldability for complex shape products. In addition, it is excellent in dimensional stability after molding, and has an excellent effect in weight reduction and NVH (sound absorption function) of the product.
접착필름(110)은 부직포를 접착하는데 사용되는 것을 이용한다. 이러한 접착필름(110)으로는 핫멜트 나일론 필름이나 올레핀계열 접착필름을 이용할 수 있다.The
핫멜트 나일론 필름은 저온에서 접착이 가능할 뿐만 아니라 우레탄계열의 접착에 많이 이용되며, 우레탄발포누액방지에도 많이 사용되고 있다. 올레핀계열 접착필름은 부직포 접착 뿐만 아니라 통상적으로 자동차용 내장재의 기재접착에 많이 이용된다.Hot melt nylon film is not only capable of adhesion at low temperature, but also widely used for urethane-based adhesion, and is widely used for preventing urethane foam leakage. Olefin-based adhesive films are commonly used for bonding non-woven fabrics as well as substrates for automotive interior materials.
이러한 접착필름(110)은 열가압을 통해 일체로 융착되게 되는데, 이는 통상의 기술로 이루어지는 것으로 여기서는 그 상세한 설명을 생략한다.
The
고강성 부직포(120)는 인체에 무해한 천연섬유와 화학섬유로 이루어지고, 특히 성형후 가로 및 세로방향의 수치 변화와 같은 물성치 및 인장강도가 높은 부직포를 이용한다. High-strength
이러한 고강성 부직포(120)는 천연섬유 20~70중량%, 저융점 합성섬유 20~70중량%, 그리고 저융점의 초성분과 고융점의 심성분으로 이루어진 점착용 시스코어형 복합섬유 10~60중량%로 이루어진다.
The high-strength
그리고, 저융점 합성섬유는 폴리올레핀·폴리아미드 및 폴리에스테르 중에서 선택된 1종 이상으로 이루어진 것을 이용한다. 이때, 저융점 합성섬유의 사용량은 20중량% 미만이면 인장강도가 저하되고, 그 사용량이 70중량%를 초과하면 점착용 시스코어용 복합섬유의 사용량이 상대적으로 적어져서 점착력이 떨어지거나 수축현상이 일어나는 문제가 발생한다.
And low melting point synthetic fiber uses what consists of 1 or more types chosen from polyolefin polyamide and polyester. At this time, when the amount of the low melting point synthetic fiber is less than 20% by weight, the tensile strength is lowered. When the amount of the low melting point synthetic fiber is more than 70% by weight, the amount of the composite fiber for the adhesive sheath core is relatively small, resulting in a decrease in adhesive strength or shrinkage. A problem arises.
수축방지용 천연섬유는 케나프·황마·아마·양마 및 코코넛 중에서 선택된 1종 이상으로 이루어진다. 이때, 수축방지용 천연섬유의 사용량은 20중량% 미만이면 수축현상이 발생하며, 그 사용량이 70중량%를 초과하면 인장강도를 높이면서 수축현상을 방지할 수 있으나, 점착용 시스코어용 복합섬유의 사용량이 상대적으로 적어져서 점착력이 떨어진다.
Shrink-resistant natural fibers consist of one or more selected from kenaf, jute, flax, sheep and coconut. At this time, if the amount of the natural fiber used for preventing shrinkage is less than 20% by weight, shrinkage occurs. If the amount is more than 70% by weight, the shrinkage phenomenon can be prevented while increasing the tensile strength. This becomes relatively small and adhesive force falls.
점착용 시스코어형 복합섬유의 사용량은 10중량% 미만이면 형태유지 즉 섬유와 섬유사이의 점착력이 약해지는 문제가 발생할 수 있으며, 그 사용량이 60중량%를 초과하면 인장강도가 떨어지고 수축현상을 발생한다. 또한, 점착용 시스코어형 복합섬유는 고가이기 때문에 경제성이 떨어지는 문제점이 있다.
If the amount of the adhesive ciscore-type composite fiber is less than 10% by weight, the shape retention, that is, the adhesive strength between the fiber and the fiber may be weakened, and when the amount is more than 60% by weight, the tensile strength drops and shrinkage occurs. . In addition, since the adhesive ciscore-type composite fiber is expensive, there is a problem inferior in economic efficiency.
