화물트림(luggage trim)의 제조방법Manufacturing method of cargo trim

본 발명은 화물트림(luggage trim)의 제조방법에 관한 것으로서, 더욱 상세하게는 폐폴리에틸렌 수지를 이용하여 발포제를 첨가하고 압출하여 발포성형함으로써 중량을 줄이고 원가를 절감할 수 있으며, 재사용이 가능한 화물트림(luggage trim)의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a luggage trim, and more particularly, by adding a foaming agent and extruding foaming by using a waste polyethylene resin to reduce the weight and reduce the cost, reusable cargo trim It relates to a method for producing a (luggage trim).

일반적으로 종래의 화물트림은 1차적으로 압출하여 보드를 제조한 다음, 폴리에틸렌레프탈레이트 부식포를 보드 표면에 열융착시켜 제조한 다음, 압출 성형으로 트림을 제조하고 있다.In general, the conventional cargo trim is manufactured by first extruding a board, then heat-sealing polyethylene lephthalate corroded board to the board surface, and then manufacturing a trim by extrusion molding.

그리고, 제조된 화물트림을 장착하는 방법은 스크류와 패스너(fastner)를 사용하여 냉간장착되고 있다.In addition, the method of mounting the manufactured cargo trim is cold mounted using a screw and a fastener.

그러나, 상기와 같은 화물트림은 비교적 부피가 크며 과다한 패스너와 스크류의 사용으로 탈착 및 장착이 어려운 문제가 있다.However, the cargo trim as described above is relatively bulky, and there is a problem in that detachment and mounting are difficult due to the use of excess fasteners and screws.

따라서, 본 발명자는 상기와 같은 종래의 화물트림의 문제점을 해결하기 위하여 폐폴리에틸렌 수지를 발포한 다음 압축 성형하여 이를 끼움식으로 장착할 수 있도록 화물트림의 제조방법을 개발하게 되었다.Therefore, the present inventors have developed a method of manufacturing a cargo trim so that the waste polyethylene resin is foamed and then compression molded to be fitted in order to solve the problems of the conventional cargo trim as described above.

본 발명은 경량이며, 탈착 및 장착이 용이한 화물트림을 제조하는 방법을 제공하는데 그 목적이 있다.An object of the present invention is to provide a method for manufacturing a cargo trim that is light in weight and easily removable and mounted.

이하, 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail.

본 발명은 폐폴리에틸렌 수지를 이용하여 화물트림을 제조하는 데 있어서, 페폴리에틸렌 수지를 통상의 방법으로 분쇄한 다음, 여기에 발포제를 10∼15중량%를 첨가하여 발포하여 보드를 제조한 다음, 이를 압축성형하여 끼움식으로 장착하는 것을 그 특징으로 한다.In the present invention, in manufacturing a cargo trim using waste polyethylene resin, the polypropylene resin is pulverized by a conventional method, and then foamed by adding 10 to 15% by weight of a blowing agent to prepare a board, and then It is characterized by mounting by compression molding.

이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.

본 발명은 화물트림재의 중량을 감소시키면서 탈착 및 장착이 용이한 화물트림을 제조하는 방법에 있어서, 우선 본 발명에서 사용되는 수지는 폐폴리에틸렌 수지로서 폐재료를 이용함으로써 원가절감의 효과를 얻을 수 있다.The present invention provides a method for manufacturing a cargo trim that is easy to remove and install while reducing the weight of the cargo trim material. First, the resin used in the present invention can obtain cost reduction effect by using waste materials as waste polyethylene resin. .

구입되어 세척한 폐폴리에틸렌 수지를 통상의 방법으로 분쇄한 다음, 이를 2축 압출기내에서 발포제를 첨가하여 약 50%를 발포시켜 보드를 제조한다. 이때, 발포제로는 아조디카본아미드(Azodicarbonamide) 또는 변성 아조디카본아미드를 첨가할 수 있으며, 그 첨가량은 10∼15중량%이다.The purchased and washed waste polyethylene resin is ground in a conventional manner, and then foamed in a twin screw extruder to foam about 50% to prepare a board. In this case, as the blowing agent, azodicarbonamide or modified azodicarbonamide may be added, and the amount thereof is 10 to 15% by weight.

이와 같이 50% 발포된 보드는 종래의 보드에 비하여 중량을 50%정도 감소시킬 수 있다.Thus 50% foamed board can reduce the weight by 50% compared to the conventional board.

그리고 나서 발포된 보드를 압출성형하는데, 이때 성형의 방법은 통상의 압축성형과 동일하다.The foamed board is then extruded, where the method of molding is the same as for conventional compression molding.

상기와 같은 공정을 거쳐 압축성형된 보드를 차량에 장착할 경우 종래의 보드가 폴리에틸렌테레프탈레이트 부직포와 보드가 적층된 구조를 압축성형하여 장착시에 패스너나 스크류를 이용하여 장착하던 것과는 달리 끼움식으로 장착할 수 있으므로 탈착 및 장착이 용이할 뿐만 아니라 재생 측면을 고려하여 설계가 가능하다.In the case where the compression molded board is mounted on a vehicle through the above process, the conventional board compresses the structure in which the polyethylene terephthalate nonwoven fabric and the board are laminated, and is fitted by using a fastener or a screw at the time of mounting. As it can be installed, it is easy to remove and install, and it is possible to design in consideration of regeneration aspect.

뿐만 아니라 보드가 50% 발포체이므로 충격에도 강할 뿐만 아니라 고유진동수 성능도 우수하다.In addition, since the board is 50% foam, it is not only impact-resistant but also has excellent natural frequency performance.

상기 본 발명의 화물트림을 제조하는 방법에 있어서 압출이나 발포시의 시간, 온도 또는 가압압력은 종래와 유사하다.In the method of manufacturing the cargo trim of the present invention, the time, temperature, or pressure during extrusion or foaming are similar to those of the prior art.

이와 같이 본 발명의 제조방법은 폐폴리에틸렌 수지를 이용함으로써 원가를 절감하며 중량이 가볍고 탈착 및 장착이 용이하여 해당 분야에 유용하게 사용할 수 있다.As described above, the manufacturing method of the present invention can reduce the cost by using waste polyethylene resin, light weight, easy removal and installation, and can be usefully used in the field.
