본 발명은 플라스틱 골판지(corrugated cardboard)에 관한 것으로, 더욱 상세하게는 물품을 포장하기 위한 플라스틱 골판지를 은나노 입자를 첨가하여 제작함으로써 살균, 멸균 및 항균 기능을 부여할 뿐만 아니라 내구성이 향상되어 상품성을 증대시킬 수 있는 플라스틱 골판지 제조방법에 관한 것이다.The present invention relates to a plastic cardboard (corrugated cardboard), more specifically, to produce a plastic corrugated cardboard packaging for the addition of silver nanoparticles to provide sterilization, sterilization and antibacterial function as well as to improve the durability to increase the marketability It relates to a plastic corrugated cardboard manufacturing method that can be made.
일반적으로 대형의 물품을 포장하기 위해서는 목재 등을 이용하여 포장하게 되는데 이러한 목재를 이용할 경우에는 운반한 후 포장재인 목재를 폐기 처분하게 되는 경우가 종종 발생되며 그 무게 또한 무거워 운반시에 어려움이 많았다.In general, in order to package large items, they are packaged using wood, etc. In the case of using such wood, it is often caused to dispose of the wood, which is a packaging material, after transportation.
따라서 재활용이란 측면과 그 환경친화적인 특성으로 인해 두께가 두꺼운 골 판지를 각종 포장용품으로 널리 활용되고 있는데 이러한 골판지는 사인 혹인 비사인 형태로 절곡된 골심지에 의해 저 중량을 유지하면서도 외부의충격을 효과적으로 완충시키거나 분산 처리할 수 있다.Therefore, due to the aspect of recycling and its environmentally friendly characteristics, thick cardboard is widely used for various packaging products. Such corrugated cardboard can be effectively protected from external impacts while maintaining low weight by corrugated paper bent in a sign or non-sign form. It can be buffered or dispersed.
그러나 종이나 플라스틱 등으로 제작된 골판지가 장시간 사용되거나 재활용될 경우에는 주변환경에 의해 쉽게 오염이 되므로 포장된 물품에도 그 영향을 미치게 되는 문제점이 있었다.However, when corrugated paper made of paper or plastic is used or recycled for a long time, it is easily polluted by the surrounding environment, which has a problem of affecting the packaged goods.
본 발명은 상기한 종래 기술의 사정을 감안하여 이루어진 것으로, 본 발명의 목적은 물품을 포장하기 위한 플라스틱 골판지를 은 나노 입자를 첨가하여 제작함으로써 살균, 멸균 및 항균 기능을 부여할 뿐만 아니라 내구성이 향상되어 상품성을 증대시킬 수 있는 플라스틱 골판지 제조방법을 제공하는 데 있다.The present invention has been made in view of the above-described circumstances of the prior art, and an object of the present invention is to produce plastic corrugated cardboard for packaging an article by adding silver nanoparticles, thereby providing sterilization, sterilization and antibacterial functions as well as improving durability. It is to provide a plastic corrugated cardboard manufacturing method that can increase the marketability.
상기한 목적을 달성하기 위해, 본 발명의 바람직한 일 실시예에 따라, 플라스틱 골판지 제조방법은, 합성수지 80-90중량%와 은나노 입자 10-20 중량%의 원료를 마련하여 혼합하는 단계와, 상기 혼합된 원료를 180-200℃에서 2-5분 동안 압출하는 단계와, 상기 압출 단계에서 배출되는 원료를 골판지 형상의 몰드에서 성형시키는 단계와, 상기 성형기에서 형성된 제품을 인출하는 단계, 및 상기 인출된 제품을 일정한 크기로 절단하는 단계를 포함한다.In order to achieve the above object, according to a preferred embodiment of the present invention, the plastic corrugated cardboard manufacturing method, the step of preparing and mixing the raw material of 80-90% by weight of synthetic resin and 10-20% by weight of silver nanoparticles, and the mixing Extruding the prepared raw material at 180-200 ° C. for 2-5 minutes, molding the raw material discharged from the extruding step in a cardboard-shaped mold, withdrawing the product formed in the molding machine, and Cutting the product to a constant size.
이때 상기 은 나노 입자의 농도는 3000PPM 이상이며, 은 나노 입자의 용융점이 상기 합성수지의 용융점보다 높은 것이 바람직하다.At this time, the concentration of the silver nanoparticles is 3000PPM or more, and the melting point of the silver nanoparticles is preferably higher than the melting point of the synthetic resin.
그리고 상기 합성수지는 폴리프로필렌 혼성 중합체(polypropylene copolymer)이다.The synthetic resin is a polypropylene copolymer.
이하, 본 발명에 대해 도면을 참조하여 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail with reference to drawings.
도 1 은 본 발명의 일실시예에 따른 플라스틱 골판지 제조방법의 흐름도이고, 도 2 는 도 1 에 따라 제작된 플라스틱 골판지의 개략적인 사시도이다.1 is a flow chart of a plastic corrugated cardboard manufacturing method according to an embodiment of the present invention, Figure 2 is a schematic perspective view of a plastic corrugated cardboard produced according to FIG.
도면에 도시된 바와 같이, 도면부호 10 으로 기재된 본 발명의 플라스틱 골판지의 제조방법은 우선적으로 합성수지 80-90중량%와 은나노 입자 10-20 중량%의 원료를 마련하여 혼합한다(S10).As shown in the figure, the manufacturing method of the plastic corrugated cardboard of the present invention described by
본 발명에 따른 실시예에서는 상기 합성수지를 폴리프로필렌 혼성 중합체(polypropylene copolymer)를 사용하였으며 상기 은나노 입자의 농도를 3000PPM 이상인 것이 바람직하다.In the embodiment according to the present invention, the synthetic resin is used a polypropylene copolymer (polypropylene copolymer) and the concentration of the silver nanoparticles is preferably at least 3000PPM.
이는 은 나노의 입자의 농도가 제품 중량 Kg당 200PPM 이상을 유지하기 위한 것이며 이렇게 함으로서 생산되는 플라스틱 골판지(10)의 항균력이 99.9% 이상 유지되기 때문이다.This is because the concentration of the particles of the silver nano is to maintain more than 200PPM per kg of product weight and thus the antibacterial activity of the plastic
그리고 은 나노 분말과 고밀도 합성수지를 혼합할 경우에는 입자의 평균 외경을 2-3mm로 하는 것이 바람직 한데 이는 합성수지의 흐름을 균일하게 형성시키기 때문이다.In addition, when the silver nano powder and the high-density synthetic resin are mixed, the average outer diameter of the particles is preferably 2-3 mm because the uniform flow of the synthetic resin is formed.
또한 상기 은 나노 입자의 용융점이 합성수지의 용융점보다 높은 것이 바람직한데 이는 원재료 수지보다 은 나노 혼합 수지의 비율(량)이 현저히 낮기 때문에 원재료 수지내에서의 은 나노의 균일한 분포를 위해 은 나노 혼합 수지의 용융 흐름성을 높이기 위한 것으로 이때의 용융점 차이가 약 15-20%인 것이 바람직하다.In addition, it is preferable that the melting point of the silver nanoparticles is higher than the melting point of the synthetic resin. Since the ratio (amount) of the silver nanomixture resin is significantly lower than that of the raw material resin, the silver nanomixing resin is used for uniform distribution of silver nanoparticles in the raw material resin. In order to improve the melt flow rate of the melt point difference is preferably about 15-20%.
그 후 상기 혼합된 원료를 압출기에서 180-200℃로 압출하게 된다(S20).Thereafter, the mixed raw material is extruded at 180-200 ° C. in an extruder (S20).
이때 상기 혼합원료가 상기 압출기의 스크류 내에서 3분 이내에 배출하게 되는데 이는 혼합원료가 압출기의 스크류 내에서 장시간 체류하게 되면 은 나노 입자의 산화가 발생하기 때문이다.At this time, the mixed raw material is discharged within 3 minutes in the screw of the extruder, because the oxidation of silver nanoparticles occurs when the mixed raw material stays in the screw of the extruder for a long time.
만약 은 나노가 산화현상이 발생하면, 항균력이 급격하게 감소하게 되므로 제품생산시 스크류 내에서의 흐름성을 좋게 하기 위해서 용융 흐름 지수(melting index)를 1.0 이상인 제품을 사용해야 하며 산화를 발생시키는 온도와 압출기의 스크류 내에서의 체류시간을 줄여야 한다.If the silver nanoparticles are oxidized, the antimicrobial activity will be drastically reduced. Therefore, in order to improve the flowability in the screw during the production, the product must use the product with a melt index of 1.0 or higher. The residence time in the screw of the extruder should be reduced.
다음에는 상기 압출 단계에서 배출되는 원료를 골판지 형상의 몰드에서 성형시키고(S30), 성형기에서 형성된 제품을 인출한다(S40).Next, the raw material discharged from the extrusion step is molded in a cardboard-shaped mold (S30), and the product formed in the molding machine is taken out (S40).
최종적으로 상기 인출된 제품을 일정한 크기로 절단하면(S50) 도 2 의 플라스틱 골판지(10)를 얻을 수 있게 된다.Finally, when the drawn product is cut to a predetermined size (S50), the
본 발명의 상기와 같은 방법에 따라, 물품을 포장하기 위한 플라스틱 골판지를 은 나노 입자를 첨가하여 제작함으로써 살균, 멸균 및 항균 기능을 부여할 뿐만 아니라 내구성이 향상되어 상품성을 증대시킬 수 있는 효과가 발생한다.According to the above-described method of the present invention, by producing the plastic corrugated cardboard for packaging the article by adding the silver nanoparticles, not only imparts sterilization, sterilization and antibacterial function, but also improves durability to increase the commercial properties occur do.
본 발명은 기재된 실시예에 한정되는 것은 아니고, 본 발명의 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형할 수 있음은 이 기술의 분야에서 통상의 지식을 가진 자에게 자명하다. 따라서 그러한 변형예 또는 수정예들은 본 발명의 특허청구범위에 속한다 해야 할 것이다.It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
