본 발명은 마를 혼합한 보드의 제조 방법 및 그 방법에 의해 제조한 마를 혼합한 보드에 관한 것으로, 특히 차량의 내장재에 사용되는 보드로서 소립자로 분쇄한 마 섬유와 폴리프로필렌을 혼합하여 보드층을 성형하고, 그 성형한 보드층에 부직포층을 부착한 마를 혼합한 보드의 제조 방법 및 그 방법에 의해 제조한 마를 혼합한 보드에 관한 것이다.The present invention relates to a method of manufacturing a board mixed with hemp and a board mixed with a hemp manufactured by the method. In particular, the board layer is formed by mixing hemp fibers pulverized into small particles and polypropylene as a board used for interior materials of a vehicle. The board | substrate which mixed the hemp manufactured by the method, and the board | substrate which mixed the hemp with a nonwoven fabric layer to this molded board layer were mixed.
일반적으로 자동차의 내부에는 차체 프레임에 설치되어 강도 및 내충격성을 유지하고, 보온 단열 차음을 위한 커버재로서 내장재가 사용된다.In general, the interior of the vehicle is installed in the vehicle body frame to maintain strength and impact resistance, and the interior material is used as a cover material for thermal insulation insulation.
이러한 차량의 내장재는 트렁크 바닥, 뒷좌석 후면부, 도어 등의 차량의 내부에 다양하게 설치되고 있다.Interior materials of such vehicles are variously installed in the interior of the vehicle, such as a trunk floor, rear seat rear portion, door.
상기와 같이 차량의 내부 내장재로 사용되는 종래의 보드는, 합성 수지만을 이용하여 성형한 보드와, 톱밥이나 왕겨를 혼합하여 성형한 보드가 있으며, 이와 같은 종래의 보드는 성형시 뒤틀림이 크고 보드의 융착면이 매끄러운 경우가 많아 제조시 엠보싱 처리를 위한 공정을 추가로 필요로 한다.As described above, conventional boards used as interior materials of a vehicle include boards formed using only synthetic resins and boards formed by mixing sawdust or rice hulls. The fusion surface of the is often smooth and requires a further step for the embossing treatment during manufacturing.
이는 보드의 융착면이 매끄러운 경우 부직포의 부착에 어려움이 있기 때문에 그러한 문제의 해결 방안으로서 엠보싱 처리 공정을 통해 보드에 인위적으로 융착을 시키는 것이다.This is because when the fusion surface of the board is smooth, it is difficult to attach the non-woven fabric is to artificially fusion to the board through the embossing process as a solution to such a problem.

이하, 본 발명의 바람직한 실시예에 의한 마를 혼합한 보드의 제조 방법 및 그 방법에 의해 제조한 마를 혼합한 보드에 대하여 첨부된 도면을 참조하여 상세히 설명하기로 한다.Hereinafter, a method of manufacturing a board mixed with hemp according to a preferred embodiment of the present invention and a board mixed with hemp prepared by the method will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 바람직한 실시예에 따른 마를 혼합한 보드의 제조 방법을 나타낸 제조 공정도이다.1 is a manufacturing process diagram showing a manufacturing method of a board mixed with hemp according to a preferred embodiment of the present invention.
본 발명에 따른 마를 혼합한 보드의 제조 방법은 도 1에 도시된 바와 같이, 차량의 내장재에 사용되는 보드의 제조 방법으로서, 먼저 마 섬유를 소립자로 분쇄하고, 상기 소립자로 분쇄된 마 섬유와 폴리프로필렌(P.P:polypropylene)을 섞어 혼합한다. 이때, 분쇄된 마 섬유의 소립자는 3mm 내외로 분쇄함이 바람직하며, 이는 폴리프로필렌과의 혼합이 용이하게 이루어지도록 한다.As shown in FIG. 1, a method of manufacturing a board mixed with hemp according to the present invention is a method of manufacturing a board used for interior materials of a vehicle. First, the hemp fiber is pulverized into small particles, and the hemp fiber and poly pulverized with the small particles are Mix and mix propylene (PP: polypropylene). At this time, the small particles of the crushed hemp fiber is preferably pulverized to about 3mm, which makes it easy to mix with polypropylene.
다음, 상기 혼합 단계에서 소립자로 분쇄된 마 섬유와 폴리프로필렌이 혼합된 혼합체를 130℃로 가열하여 1차 용융시킨다.Next, the mixed mixture of hemp fibers and polypropylene pulverized into small particles in the mixing step is first melted by heating to 130 ℃.
이후, 상기 1차 용융 단계에서 용융이 이루어진 용융체는 압출을 통해 배출되면서 소정의 크기로 절단되어 칩을 생성한다. 여기서, 절단되는 칩의 크기는 4 ~ 5mm 미만의 크기로 절단이 이루어지게 된다.Thereafter, the molten melted in the primary melting step is cut into a predetermined size while being discharged through extrusion to produce a chip. Here, the size of the chip to be cut is made to a size of less than 4 ~ 5mm.
다음, 상기 단계에서 생성된 칩은 시트기에 넣고 130 ~ 140℃로 가열하여 2차 용융시키게 되며, 이어서 상기 2차 용융 단계에서 만들어진 용융체는 다이스를 통해서 배출되면서 롤러에 적용되어 시트를 생성하게 된다.Next, the chip produced in the step is put into a sheet machine and heated to 130 ~ 140 ℃ to secondary melt, then the melt produced in the secondary melting step is applied to the roller while being discharged through the die to produce a sheet.
다음, 상기 단계에서 생성된 시트를 이용하여 보드의 제조를 완료하는 방법은 하기에서 설명하는 2가지의 방법 중 하나에 의해 완성된다.Next, the method of completing the manufacture of the board using the sheet generated in the above step is completed by one of two methods described below.
먼저, 첫 번째는 시트를 뽑으면서 롤러와 부직포를 함께 적용시켜 시트에 부 직포를 부착시킴으로써 보드의 제조를 완료하는 공정이 될 수 있다.First, the first process may be a process of completing the manufacture of the board by applying the nonwoven fabric to the sheet by applying the roller and the nonwoven fabric while pulling out the sheet.
이는, 상기 시트 생성단계에서 롤러에 적용되는 시트에 부직포를 적용하는 경우이거나, 롤러를 통해 배출되어 생성되는 시트를 2차 롤러로 통과시키면서 이때 부직포를 적용시키는 방법 중 하나가 적용될 수 있다.This may be the case in which the nonwoven fabric is applied to the sheet applied to the roller in the sheet generating step, or one of the methods of applying the nonwoven fabric at this time while passing the sheet generated by being discharged through the roller to the secondary roller.
한편, 두 번째는 상기 시트 생성단계에서 생성된 시트를 금형에 넣어 오븐을 통과시킨 상태에서, 부직포가 부착된 금형을 오븐을 통과한 시트체에 프레싱하여 부직포를 부착시킴으로써 보드의 제조를 완료하는 공정이 적용될 수 있다.On the other hand, the second is a step of completing the manufacturing of the board by attaching the nonwoven fabric by pressing the mold with a nonwoven fabric to the sheet body passing through the oven in the state that passed the oven by inserting the sheet produced in the sheet generating step into a mold This can be applied.
이때, 시트가 넣어지는 금형과 부직포가 부착된 금형은 서로 대응하는 형상의 암 또는 수 형상의 금형을 의미한다.In this case, the mold into which the sheet is put and the mold to which the nonwoven fabric is attached mean a mold having a female or male shape corresponding to each other.

상술한 바와 같이 본 발명에 의한 마를 혼합한 보드의 제조 방법 및 그 방법에 의해 제조한 마를 혼합한 보드에 의하면, 뒤틀림이 적고 마 섬유가 혼입된 부분이 융기되어 부직포의 부착이 용이한 효과가 있다.According to the manufacturing method of the board which mixed the hemp according to the present invention as described above, and the board which mixed the hemp manufactured by the method, the warpage is less and the portion where the hemp fiber is mixed is raised to facilitate the attachment of the nonwoven fabric. .
또한, 기존의 톱밥이나 왕겨를 사용한 보드에 비해 마 섬유소의 길이와 응집성의 증대로 결착력이 향상됨은 물론, 형상의 변경을 방지하며, 내장재로서의 강도 및 내충격성이 증대되는 효과를 제공한다.In addition, the binding force is improved by increasing the length and cohesiveness of hemp fiber compared to the board using the sawdust or chaff, as well as preventing the change of shape, and provides the effect of increasing the strength and impact resistance as interior materials.
