식물섬유 발포재 제작방법{MANUFACTURING METHOD OF PLANT FIBER FOAM}MANUFACTURING METHOD OF PLANT FIBER FOAM}

본 발명은 발포재 제작방법에 관한 것으로, 특히 자연분해가 가능한 천연 식물섬유 발포재에 관한 것이다.The present invention relates to a method for producing a foam material, and in particular to a natural plant fiber foam material capable of natural decomposition.

발포물질은 무게가 가볍고 방화 및 충격흡수 기능을 가지고 있기 때문에 포장재나 충전물, 용기, 케이스 같이 다양한 분야에 대량으로 사용되고 있다. 일반적으로 발포물질은 기제와 발포제를 이용하여 제조한다. 특히 열을 가해 줌으로써 발포제에는 대량의 기체가 발생되고 기제는 녹거나 부드러워져서 평평한 판이나 PVC 타일, 병 모양이나 밀봉된 모양 같이 필요한 모양을 만들 수 있게 된다. 자주 사용되는 기제로는 열가소성 수지나 열경화성 플라스틱, 고무 같은 각종 인공물질이 있다. 이 외에도 현재 사용되는 사출성형이나 압출성형, 롤성형, 분사성형으로 쉽게 가공, 제작될 수 있고 적당한 고온고압 증기나 고주파, 초음파, 적외선으로 가열할 수도 있다.Due to their light weight and fire and shock absorption, they are used in large quantities in various fields such as packaging materials, fillings, containers and cases. In general, the foam material is prepared using a base and a blowing agent. In particular, by applying heat, a large amount of gas is generated in the blowing agent and the base is melted or softened to form the required shape such as flat plate, PVC tile, bottle shape or sealed shape. Frequently used bases include various artificial materials such as thermoplastic resins, thermosetting plastics and rubber. In addition, it can be easily processed and manufactured by current injection molding, extrusion molding, roll molding, and injection molding, and can be heated by appropriate high temperature, high pressure steam, high frequency, ultrasonic wave, and infrared ray.

그러나 위에서 설명한 기존 기술의 단점은 사용 물질에 따라 서로 다른 특정한 발포기술과 적합한 기계설비를 사용해야 하므로 실제 제작에 있어 유연성이 부족하다는 문제가 있다. 이 밖에도 기제의 원료 가격이 비쌀 뿐 아니라 쉽게 분해되지 않아 사용 후에는 항상 쉽게 처리할 수 없는 대량의 폐기물이 발생하여 심각한 환경문제를 파생시키는 문제점을 내표하고 있다.However, the disadvantage of the existing technology described above has a problem in that there is a lack of flexibility in the actual production because the use of different specific foaming technology and suitable equipment depending on the material used. In addition, the price of the raw material of the base is not only expensive, it does not easily decompose, and after use, a large amount of waste is generated, which causes serious environmental problems.

따라서 식물섬유 발포재를 제작할 때는 자연분해가 가능한 식물섬유를 이용하여 위에서 설명한 기존 기술의 문제점을 해결할 필요가 있다.
Therefore, when manufacturing plant fiber foam material, it is necessary to solve the problems of the existing technology described above by using plant fiber which is naturally degradable.

위와 같은 문제점을 해결하기 위한 본 발명의 주요 목적은 식물섬유 발포재의 제작방법을 제공하는 것이다.The main object of the present invention for solving the above problems is to provide a method for producing a plant fiber foam material.

상기 목적을 달성하기 위한 본 발명의 주요 내용은, 식물섬유와 발포제, 점착제, 충전제, 발화지연제를 교반기에 넣고 섞는 혼합처리를 하여 걸쭉한 모양의 균일 혼합물을 만든다. 균일 혼합물을 성형용기나 성형몰드에 붓거나 주입한다. 가압장치를 이용한 가압처리를 실시하여 정해진 압력을 가해 준다. 그 후 발포제의 발포온도보다 높아질 때까지 가열처리를 실시하고 조금 더 지나면 다공성의 발포구조를 가진 발포재로 변한다. Main contents of the present invention for achieving the above object, by mixing the plant fiber and the blowing agent, pressure-sensitive adhesive, filler, fire retardant into a stirrer to make a uniform mixture of thick shape. The homogeneous mixture is poured or poured into a molding container or molding mold. The pressurization process using the pressurization device is applied to apply a predetermined pressure. Thereafter, the heat treatment is performed until the foaming temperature is higher than the foaming temperature, and after a while, the foaming material has a porous foam structure.

위에 기술된 식물섬유는 볏짚이나 벼 낟알 껍데기, 보리줄기, 옥수수잎, 사탕수수잎, 야자껍데기, 목초 또는 그 조합물, 특히 식물섬유입자(Fiber Particulate Composite, FPC)를 사용할 수 있다. 전분을 포함한 점착제는 점도를 증가시키는 데 사용하여 워커빌리티를 개선시킬 수 있다. 탄산칼슘이 포함된 발화지연제는 연소를 막거나 속도를 늦추는 데 사용되어 방화효과를 증진시켜 준다. The plant fibers described above may use rice straw or rice grain shells, barley stems, corn leaves, sugar cane leaves, palm husks, grasses or combinations thereof, in particular Fiber Particulate Composite (FPC). Adhesives containing starch can be used to increase the viscosity to improve workability.

이하, 첨부의 도면을 참조하여 본 발명을 상세히 설명하며, 첨부의 도면과 도면부호를 참조하면 본 발명의 실시방법에 대해 더욱 자세하게 알 수 있기 때문에 본 발명의 기술분야에서 통상의 지식을 가진 자라면 이하의 상세한 설명을 통해 용이하게 실시할 수 있다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, and the present invention can be understood in more detail with reference to the accompanying drawings and reference numerals. It can be easily carried out through the following detailed description.

도 1은 식물섬유 발포재 제작방법에 대한 프로세스이다. 도 1을 참조하는 바와 같이 본 발명 내용은 혼합처리(S10), 주입처리(S20), 가압처리(S30), 가열처리(S40) 단계가 순서대로 이루어지고 그 결과 특정한 모양을 가진 식물섬유 발포재가 만들어진다.1 is a process for manufacturing a plant fiber foam material. As shown in Figure 1, the present invention is a mixture treatment (S10), injection treatment (S20), pressurization treatment (S30), heat treatment (S40) step is made in order and as a result the plant fiber foam material having a specific shape Is made.

가장 먼저 시작하는 혼합처리(S10)는 식물섬유와 발포제, 점착제, 충전제, 발화지연제를 혼합기 안에 넣고 최소 3시간 동안 뒤섞으며 혼합하여 걸쭉한 모양의 균일 혼합물을 만들어 낸다. 이 중 식물섬유의 중량비는 약 10%~90%가 되도록 한다. 식물섬유는 식물섬유입자(FPC)로 할 수도 있고 자연상태의 식물 줄기와 잎사귀, 열매 껍데기, 과일 껍질, 뿌리 부분 중 최소 한 가지를 선택하여 사용할 수도 있다. 예를 들면 볏짚과 벼 낟알 껍데기, 보리줄기, 옥수수잎, 사탕수수잎, 아마잎, 죽엽, 사탕무, 목초, 야자 껍데기, 파인애플 껍질, 우엉 중 최소 한가지로 사용할 수 있다.Mixing treatment (S10) that is started first puts the plant fiber and foaming agent, pressure-sensitive adhesive, filler, fire retardant in the mixer and mix for at least 3 hours to form a thick uniform mixture. Among them, the weight ratio of plant fiber is about 10% to 90%. The plant fiber may be a plant fiber particle (FPC) or at least one selected from natural plant stems and leaves, fruit peels, fruit peels, and root parts. For example, it can be used as at least one of rice straw, rice kernels, barley stems, corn leaves, sugar cane leaves, flax leaves, bamboo leaves, sugar beets, grasses, coconut shells, pineapple peels, and burdock.

발포제는 에틸렌초산 비닐(EVA)이나 발포 폴리에틸렌(EPE), 폴리유산(Poly Lactic Acid, PLA)을 사용할 수 있다. 예를 들어 발포제가 200℃의 발포온도를 가지는 경우, 온도를 220℃로 하여 발포온도보다 높은 온도에 다다랐을 때는 이산화탄소처럼 화학적으로 불활성을 띤 대량의 기체를 발생시킬 수 있기 때문에 다공성의 개방성 또는 밀폐성 구멍을 만드는 데 사용된다. The blowing agent may be ethylene vinyl acetate (EVA), expanded polyethylene (EPE), polylactic acid (Poly Lactic Acid, PLA). For example, when the blowing agent has a foaming temperature of 200 ° C., a porous open or airtight hole can be generated when the temperature is set to 220 ° C., so that a large amount of chemically inert gas such as carbon dioxide can be generated. Used to make it.

충전제는 석회분말을 포함할 수 있다. 점착제는 전분을 포함하여 점도를 높이는 데 사용하고 워커빌리티(workability)를 개선시킨다. 발화지연제는 탄산칼슘을 사용하여 연소를 막거나 속도를 늦추는 데 사용하면 방화효과를 높여준다. 이 밖에도 발화지연제는 에폭시 접착제와 활성탄소 발화지연제를 포함할 수 있다. 이 중 활성탄소 발화지연제는 활성탄소 효과를 가진 발화지연제로서 화재가 발생했을 때 연소를 방지할 뿐 아니라 연소시 발생하는 연기를 흡착하여 화재현장의 짙은 연기를 감소시켜 주는 우수한 성질을 가지고 있어 현재 세계에서 가장 친환경적이고 안전한 발화지연제로 알려져 있다. 활성탄소 발화지연제는 일반적으로 천연 탄소광물에 특수처리를 하여 만들어 낸다. 그 특성은 상온~200℃일 때 안정적으로 변형되지 않는 상태를 유지하다가 열을 받아 온도가 200℃보다 높아지면 두께가 수십배에서 수백배까지 급속도로 팽창하여 부피가 늘어난 벌레가 꿈틀거리는 모양의 분말로 변화되는 것이다. 연소되는 표면에는 차단 탄소층이 생겨 열을 막아 주면서 공기의 흐름도 감소시켜 화재를 예방하는 효과를 가진다.The filler may comprise lime powder. Tackifiers are used to increase viscosity, including starch, and improve workability. Fire retardants can be used to prevent or slow down combustion by using calcium carbonate to increase the fire resistance. In addition, the fire retardant may include an epoxy adhesive and an activated carbon fire retardant. Among these, activated carbon ignition retardant is an ignition retardant with activated carbon effect, which not only prevents combustion when a fire occurs, but also has excellent properties of adsorbing smoke generated during combustion to reduce dense smoke at the fire site. It is now known as the world's greenest and safest fire retardant. Activated carbon fire retardants are usually produced by special treatment of natural carbon minerals. Its characteristic is that it is a powder that looks like a worm that grows in volume by rapidly expanding from tens to hundreds of times when its temperature is higher than 200 ℃ while being stable and not deformed when it is from room temperature to 200 ℃. It is changing. Blocking carbon layer is formed on the surface to be burned to prevent heat by reducing the flow of air while preventing heat.

그 다음으로는 주입처리(S20)를 실시한다. 쏟거나 압출하는 방식으로 걸쭉한 모양의 균일 혼합물을 특정한 모양을 가진 성형용기나 성형몰드에 붓거나 주입한 후 다시 가압처리(S30)를 실시하여 밀집도를 강화시킨다. 가압처리는 가압장치를 이용하여 압력을 가하도록 하고, 가압장치는 유압기나 고압공기펌프를 사용할 수 있다. Next, an injection process (S20) is performed. After pouring or injecting a uniform mixture of thick shape into a molding container or a molding mold having a specific shape by pouring or extruding, the pressure treatment (S30) is performed again to strengthen the compactness. The pressurization treatment is to apply pressure using a pressurization apparatus, and the pressurization apparatus may use a hydraulic pressure or a high pressure air pump.

마지막으로 실시하는 가열처리(S40)는 가열장치를 이용하여 성형용기나 성형몰드 중 균일 혼합물의 온도를 220℃정도로 발포제 발포온도보다 높게 10~60초간 유지시키는 것이다. 가열처리는 발포제의 발포작용을 촉진시키고 균일 혼합물이 다공성 발포구조를 가진 식물섬유 발포재로 변하도록 해 준다. 가열장치는 고온고압 증기나 고주파, 초음파, 적외선으로 가열하는 방식을 사용할 수 있다. The last heat treatment (S40) to be carried out is to maintain the temperature of the homogeneous mixture in the molding container or molding mold for about 10 to 60 seconds higher than the foaming agent foaming temperature using a heating device. The heat treatment promotes the blowing action of the blowing agent and allows the homogeneous mixture to turn into a plant fiber foam with a porous foam structure. The heating device may be a method of heating by high temperature, high pressure steam, high frequency, ultrasonic wave, or infrared ray.

이렇게 제작된 식물섬유 발포재는 성형용기나 성형몰드에 따라 특정한 모양을 갖출 수 있고 특정상품을 포장하는 데 직접 사용되어 방습이나 방화, 충격흡수 등의 보호기능을 제공해 준다.The plant fiber foam material thus manufactured can have a specific shape according to the molding container or molding mold and can be directly used to package a specific product to provide protection functions such as moisture proofing, fire prevention and shock absorption.

도 2는 식물섬유 발포재의 또 다른 제작방법을 보여주는 프로세스이다. 이 제작방법은 혼합처리(S10), 롤처리(S22), 가열처리(S40), 트리밍 처리(S50)를 순서대로 실시하여 이루어지며 그 결과 평평한 판 모양의 식물섬유 발포재가 만들어진다. 혼합처리(S10)와 가열처리(S40)는 도 1에서 서술된 것과 같으므로 여기서는 다시 구체적인 설명은 생략한다.Figure 2 is a process showing another method of manufacturing a plant fiber foam. This manufacturing method is carried out by sequentially performing the mixing treatment (S10), roll treatment (S22), heat treatment (S40), trimming treatment (S50) in order to produce a flat plate-like plant fiber foam material. Since the mixing treatment S10 and the heating treatment S40 are the same as described in FIG. 1, detailed descriptions thereof will be omitted here.

롤처리(S22)는 걸쭉한 모양의 균일 혼합물을 롤장치를 이용하여 일정한 두께를 가진 일정한 모양의 평평한 판으로 만들어내는 과정이다. 그 후 가열처리(S40)를 실시하면 발포제에 발포작용이 일어나 평평한 판 모양의 식물섬유 발포재로 변하게 된다. 가열처리(S40)를 할 때에는 이 밖에도 열압기 같은 것을 이용하여 가압처리를 함으로써 식물섬유 발포재의 밀도를 늘릴 수 있다.Roll processing (S22) is a process of producing a thick uniform shape mixture using a roll device to a flat plate of a constant shape having a certain thickness. Then, the heat treatment (S40) is carried out to cause the foaming agent to change into a flat plate-like plant fiber foam material. In addition, when the heat treatment (S40), the density of the plant fiber foam member can be increased by performing a pressure treatment using a heat press or the like.

마지막으로 실시하는 트리밍 처리(S50)는 트리밍 장치를 이용하여 식물섬유 발포재를 적당한 크기와 모양으로 트리밍하는 것이다.Finally, the trimming treatment (S50) to be carried out is to trim the plant fiber foam material to a suitable size and shape using a trimming device.

본 제작방법의 특징은 현재 있는 기계설비를 그대로 사용하여 발포를 일으킬 수 있고 별도의 가공기구로 교체하거나 새로 도입할 필요가 없기 때문에 다양한 분야에서 각종 식물섬유 발포물질의 발포성형에 응용될 수 있을 뿐 아니라 사용 재료 또한 실제수요에 따라 조정하여 원가를 낮출 수 있다는 점에 있다. 특히 제작과정 중 가소성이 높아 개인별 요구사항에 따라 필요한 물질과 발포제를 선택하여 첨가할 수 있기 때문에 전체 제작과정이 간편할 뿐 아니라 성형이 용이하다.This manufacturing method can be used for foaming of various plant fiber foaming materials in various fields because it can cause foaming using existing machinery as it is and does not need to be replaced or newly introduced into a separate processing tool. In addition, the materials used can be adjusted according to the actual demand to lower the cost. Particularly, the plasticity is high during the manufacturing process, so the necessary materials and foaming agents can be selected and added according to individual requirements.

본 제작방법의 또 다른 특징은 식물섬유 발포재가 필요로 하는 식물섬유는 농업생산가공 중 생겨나거나 남겨진 폐기물을 활용하여 만들어질 수 있기 때문에 자연분해가 가능하고 취득이 용이하여 환경을 보호하고 농업 폐기물 배출량을 줄일 수 있다는 점이다.Another feature of this manufacturing method is that the plant fiber required by the plant fiber foam material can be made by using the wastes generated or left during agricultural production processing. Can be reduced.
