Description
도 1은 본 발명에 따른 자동차 내장재용 기재의 제조방법에 대한 공정순서도이다.1 is a process flowchart of a method for manufacturing a substrate for automobile interior according to the present invention.
본 발명은 자동차 내장재용 기재 및 그 제조방법에 관한 것으로, 특히 천연섬유인 마와 폴리프로필렌 단섬유를 일정비율로 혼합하여 자동차 내장재용 기재와 그 내장재용 기재를 제조하는 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substrate for automobile interior materials and a method for manufacturing the same, and more particularly, to a method for manufacturing a substrate for automobile interior materials and a substrate for interior materials by mixing hemp and polypropylene short fibers, which are natural fibers, at a predetermined ratio.
종래의 자동차 내장재의 기재는 열경화성 페놀을 사용하여 화학섬유를 혼합하여 제조하거나, 폴리프로필렌 수지와 목분을 혼합한 후 압출하여 제조해오고 있다. 그런데 상기 종래의 내장재 기재의 원료로 사용되는 열경화성 수지인 페놀은 환경오염의 원인이 되고, 제조과정중에 악취를 발생시킬 뿐아니라 인체에 유해한 분진을 발생시켜 작업환경을 열악하게 하는 문제점이 있었다. 뿐만아니라 완제품 제조시 발생되는 부산물은 재활용이 불가능하여 폐기하거나 소각처리하여여 함으로써 2차 환경오염을 유발하는 원인이 되었다.BACKGROUND ART [0002] Conventional automotive interior materials have been prepared by mixing chemical fibers using thermosetting phenol, or by extrusion after mixing polypropylene resin and wood powder. However, phenol, which is a thermosetting resin used as a raw material of the conventional interior materials, has a problem of causing environmental pollution, not only odor during the manufacturing process, but also harmful dust to the human body, thereby deteriorating the working environment. In addition, by-products generated during the manufacture of finished products were not recycled and thus disposed or incinerated, causing secondary environmental pollution.
또한, 폴리프로필렌 수지와 목분을 혼합하여 압출하는 시트는 강성이 떨어지고, 무게가 상대적으로 무거워서 무게가 가벼워야 하는 자동차 내장재의 기재로서는 부적합한 단점이 있었다.In addition, the sheet to be extruded by mixing the polypropylene resin and wood powder has a disadvantage of being unsuitable as a base material of the automotive interior material that the rigidity is low, the weight is relatively heavy and the weight should be light.
이에 본 발명은 상기 종래의 자동차 내장재용 기재가 가진 문제점을 해결하기 위하여 고안된 것으로, 환경오염의 영향을 최소화하고, 제품의 강성은 증가시키면서 무게를 경량화하는 동시에 변형과 수축율에 있어서는 향상된 자동차 내장재용 기재 및 그 제조방법을 제공함에 목적이 있다. Accordingly, the present invention is designed to solve the problems of the conventional automotive interior materials, to minimize the impact of environmental pollution, increase the rigidity of the product while reducing the weight of the weight and at the same time improved deformation and shrinkage substrate for automotive interior materials And to provide a method for manufacturing the same.
상기 본 발명에 따른 자동차 내장재용 기재는 천연섬유인 마 50~70mm 단섬유와 폴리프로필렌 단섬유 40~60%가 니들펀칭으로 혼합되어 구성되고 표면에 폴리프로필렌 기포지가 부착된 구성으로 이루어진다. The substrate for automobile interior according to the present invention is composed of a natural fiber hemp 50 ~ 70mm short fibers and polypropylene short fibers 40 ~ 60% is mixed by needle punching and the polypropylene bubble paper is attached to the surface.
또한 본 발명에 따른 자동차 내장재용 기재의 제조방법은 천연섬유인 마 단섬유와 폴리프로필렌 단섬유를 혼합하여 개면하는 단계와, 상기 혼합된 마 단섬유와 폴리프로필린 단섬유를 니들펀칭하는 단계와, 니들펀칭된 폴리프로필렌과 마 단섬유의 표면에 폴리프로필렌 기포지를 부착하는 단계로 이루어진다. In addition, the manufacturing method of the base material for automobile interior according to the present invention is the step of mixing and opening the mixed fiber and the polypropylene short fiber which is a natural fiber, and the needle punching the mixed hemp fiber and polypropylene short fiber and And attaching the polypropylene bubble paper to the surface of the needle punched polypropylene and the hemp fiber.
상기한 바와 같은 본 발명에 따라 만들어지는 자동차 내장재용 기재는 종래 페놀수지, 폴리프로필렌 수지와 목분을 압출하여 만들어지는 자동차 내장재용 기재에 비하여 변형이 적을 뿐아니라 가볍고 수축율이 향상될 뿐아니라 페놀에 의한 폐 해가 발생하지 않고 오히려 천연섬유를 사용함으로써 환경친화적이다. As described above, the base material for automobile interior made according to the present invention is less deformed as compared with the substrate for automobile interior made by extruding phenolic resin, polypropylene resin and wood powder, and is light and shrinkage is not only improved, but also by phenol. It does not generate any harmful effects and is rather environmentally friendly by using natural fibers.
이하, 본 발명에 따른 자동차 내장재용 기재의 제조방법의 실시예를 첨부도면에 따라 상세히 설명한다. Hereinafter, an embodiment of a method for manufacturing a substrate for automotive interior according to the present invention will be described in detail according to the accompanying drawings.
본 발명에 따른 자동차 내장재용 기재는 천연섬유인 마 50~70mm 단섬유와 폴리프로필렌 단섬유 40~60%가 니들펀칭되어 표면에 폴리프로필렌 기포지가 부착된 구성으로 이루어진다. The substrate for automobile interior according to the present invention is composed of a natural fiber, hemp 50-70mm short fibers and polypropylene short fibers 40-60% needle punched to the surface of the polypropylene bubble paper attached.
상기 본 발명에 따른 자동차 내장재용 기재는 도 1에 도시된 바와 같이 다음의 단계를 거쳐 제조된다. The substrate for automobile interior according to the present invention is manufactured through the following steps as shown in FIG.
폴리프로필렌 단섬유와 천연섬유인 마 50~70mm의 단섬유를 혼합하여 개면한다. 이 때 마는 40~60%는 정도 사용하고, 폴리프로필렌 단섬유는 60~40%가 되게 혼합하되 서로 균일하게 배열되게 배치한다. The polypropylene short fiber and natural fiber hemp 50 ~ 70mm short fiber are mixed and opened. At this time, use about 40 ~ 60% of hemp, and mix polypropylene short fiber to be 60 ~ 40%, but arrange them evenly.
이렇게 혼합된 폴리프로필렌 단섬유와 마 단섬유를 니들펀칭한다. 니들펀칭된 것위에 폴리프로필렌으로 만들어진 기포지를 접착하여 펠트로 제조한다. Needle-punched the mixed polypropylene short fibers and hemp fibers. It is made of felt by adhering bubble paper made of polypropylene onto the needle punched one.
상기 펠트를 180~230℃의 온도로 예열한 후 형틀에 넣고 냉각시키면서 소정의 형태로 성형하여 자동차 내장재용 기재를 제조한다. 상기 예열과정은 열선을 사용하는 가열장치를 사용하거나 열풍로를 사용할 수도 있다. After pre-heating the felt to a temperature of 180 ~ 230 ℃ and put into a mold while cooling to form a predetermined shape to prepare a substrate for automotive interior materials. The preheating process may use a heating apparatus using a hot wire or use a hot stove.
상기한 바와 같이 구성된 본 발명에 따르면 페놀수지를 사용하지 않음으로써 페놀수지를 사용하여 제조과정중에 발생하는 악취나 인체에 유해한 분진이 발생하 지 않으며, 천연섬유를 마를 사용함으로써 목분을 사용하는 경우에 비하여 성형성이 우수하고, 무게가 가벼우면서도 강도 및 수축율에 있어 향상된 자동차 내장재를 제공할 수 있게 된다. According to the present invention configured as described above by using a phenol resin does not generate odor or dust harmful to the human body using the phenol resin, compared to the case of using wood powder by using hemp natural fiber It is possible to provide an automotive interior material having excellent moldability, light weight, and improved strength and shrinkage.
