난연성을 구비하는 친환경 합성목재 조성물로 이루어진 합성목재{Eco-friendly Synthetic Wood Composition Including Flame Retardant}Eco-friendly Synthetic Wood Composition Including Flame Retardant

본 발명은 난연성을 구비하는 친환경 합성목재 조성물로 이루어진 합성목재에 관한 것으로, 목분에 나노복합수지 및 난연제를 첨가하여, 난연성을 향상시킨 난연성을 구비하는 친환경 합성목재 조성물로 이루어진 합성목재에 관한 것이다.
The present invention relates to a synthetic wood made of an environmentally friendly synthetic wood composition having flame retardancy, and relates to a synthetic wood made of an environmentally friendly synthetic wood composition having a flame retardancy improved by adding a nanocomposite resin and a flame retardant to wood powder.

최근에는 천연목재에 대한 소비자의 선호도가 크게 증가하고 있으며, 특히, 천연목재의 수요가 많은 건축자재 경우 더욱 그러하며, 가구, 건축분야 등 다양한 분야에서 천연목재에 대한 소비자의 선호도가 크게 증가하고 있다. Recently, consumers' preference for natural wood has increased greatly, especially for building materials with high demand for natural wood, and consumer's preference for natural wood has increased greatly in various fields such as furniture and construction.

상기 천연목재는 우수한 외관 및 질감과, 나무특유의 재질로 인해 부드러우면서 아늑한 분위기를 자아내기 때문에 건축물의 실내외 장식에 많이 사용되고 있으나, 산림자원이 절대적으로 부족하여 사용 목재의 70% 이상을 수입에 의존하고 있는 우리나라의 경우, 천연목재의 공급이 절대적으로 부족한 실정이며, 목재의 벌목에 따른 산림 훼손과, 화재시에 유해물질 방출로 인한 환경파괴의 문제점이 발생되고 있다.The natural wood is used for interior and exterior decoration of buildings because of its excellent appearance and texture, and soft and cozy atmosphere due to the unique material of the wood, but the forest resources are absolutely insufficient, so more than 70% of the wood used for import In the case of Korea, the supply of natural wood is absolutely lacking, and there are problems of environmental damage due to forest damage and the release of harmful substances in the fire due to the logging of wood.

특히, 천연목재는 고유 물성에 의한 내수성, 내열성, 충격강도, 휨강도, 치수안정성, 난연성, 내후성, 항균성 물성이 저하되어 건축물의 외장재로 사용이 곤란한 문제점과, 목재 재질에 의한 항균성이 저하되어 수명이 단축되며, 상기 항균성 강화를 위한 용도의 구리, 비소, 크롬 계통의 방부제(일명 CCA 방부제라고 함)가 혼입, 사용되고 있는 실정이다.In particular, natural wood has a problem in that it is difficult to use as a building exterior material due to its water resistance, heat resistance, impact strength, flexural strength, dimensional stability, flame retardancy, weather resistance, and antibacterial properties due to its inherent physical properties, and deterioration of antibacterial properties by wood materials. It is shortened, and the copper, arsenic, and chromium-based preservatives (called CCA preservatives) for the purpose of strengthening the antimicrobial properties are mixed and used.

따라서, 화재 발생시에 상기 구리, 비소, 크롬 계통의 방부제 연소에 의한 유독물질이 배출되어 인체에 유해하며, 난연기능이 없어 화재가 번지는 문제점이 발생되고 있는 실정이다.
Therefore, when a fire occurs, toxic substances caused by the combustion of the preservatives of the copper, arsenic, and chromium systems are discharged and are harmful to the human body.

상기와 같은 문제점을 해결하기 위하여, 천연목재를 대체할 수 있는 소재 개발에 대한 목소리가 높아지고 있다. 이러한 대체소재로, 천연목재와 유사한 질감 및 외관을 가진 합성목재가 건축물의 내,외장재로 널리 사용되고 있다.
In order to solve the above problems, the voice for the development of materials that can replace natural wood is rising. As such a substitute material, synthetic wood having a texture and appearance similar to natural wood is widely used as interior and exterior materials of buildings.

종래의 합성목재는 원목을 얇게 자른 다음 일측면이나 양측면에 착색하여 건조시키고 접착제를 이용하여 필름등을 부착하여 건조시킨 다음 소정 길이로 절단하여 사용하도록 구비된 합판형태와, 원목이나 폐목을 가루로 분쇄한 다음 다량의 수지를 첨가한 후 가열 압착시켜 만드는 MDF(Medium Density Fiberwood)로 구분된다. 상기 MDF는 천연 무늬목이나 비닐 무늬목을 부착시켜 용도에 맞게 가공해서 사용할 수 있다.Conventional synthetic timber is cut into thin wood and then colored and dried on one side or both sides, dried by attaching a film, etc. using an adhesive, and then cut into a predetermined length and used to cut and use a solid wood or waste wood as a powder. It is divided into MDF (Medium Density Fiberwood), which is made by crushing and adding a large amount of resin, followed by heat compression. The MDF can be used by processing natural veneer or vinyl veneer to suit the application.

그러나 이러한 합성목재는 접착제 또는 다량의 수지에 포함된 유해물질로 인하여 환경을 오염시킨다. 또한, MDF는 무늬목과 판재간에 수축 팽창이 일어나며, 외부 수분 등의 영향으로 인해 부착된 무늬목이 분리되고, 갈라지거나 부패가 되는 문제점이 있다.However, these synthetic woods pollute the environment due to harmful substances contained in adhesives or large amounts of resin. In addition, the MDF shrinkage expansion between the veneer and the plate, there is a problem that the attached veneer is separated, cracked or rot due to the influence of external moisture.

또한, 최근의 합성목재는 폴리염화비닐, 폴리프로필렌 등의 열가소성 수지에 목분, 왕겨분, 펄프 분말, 볏짚 분말 등 소위 리그노셀루로오즈계 분말을 혼합한 조성물을 압출가공한 후 적당한 형상 및 크기로 제조하고 있으나, In addition, the recent synthetic wood is a suitable shape and size after extrusion processing a mixture of so-called lignocellulose-based powder such as wood flour, rice husk powder, pulp powder, rice straw powder and thermoplastic resin such as polyvinyl chloride, polypropylene, etc. Manufactured with,

이중에서 PVC를 매개체로 하는 합성목재는 PVC를 제조하는 과정에서 첨가되는 여러가지 첨가제의 유해성과 화재시 연소되며 발생되는 염화수소 개스가 인체에 치명적인 영향을 미치기 때문에 인체에 해롭다는 문제점을 갖고 있어 본 발명에서는 환경친화적인 합성수지인 폴리프로필렌 혹은 폴리에틸렌을 매개체로 사용하는 것으로 한다.Among them, synthetic wood using PVC as a medium has a problem that it is harmful to the human body because the harmful effects of various additives added in the process of producing PVC and the hydrogen chloride gas generated by burning in a fire have a fatal effect on the human body. Polypropylene or polyethylene, an environmentally friendly synthetic resin, is used as a medium.

또한 상기 합성수지 매개체중 하나인 폴리프로필렌의 경우에는 POWDER상태의 것을 사용하고 용융지수(MI)가 10정도의 원료를 사용하는 것이 바람직하다. 이는 흐름성을 좋게 하고 POWDER상태는 목분과 다양한 첨가제와의 혼련성을 좋게 하기 때문이다.In addition, in the case of polypropylene, which is one of the synthetic resin mediators, it is preferable to use a POWDER state and a raw material having a melt index (MI) of about 10. This is because the flowability is good and the powder state improves the kneading of the wood powder with various additives.

Figure 1 is an exemplary view showing a manufacturing process of the synthetic wood according to the present invention, Figure 2 shows a photographic illustration of the product made of the synthetic wood of the present invention, the present invention 65 to 75% by weight wood powder, nano composite resin 10-30% by weight, 2-4% by weight calcium carbonate, 0.01-5% by weight antioxidant, 0.01-3% by weight UV stabilizer, 1-3% by weight Mare En-hydride polypropylene as binder, 0.05-5% by weight lubricant %, 0.05 ~ 3% by weight of decabromodiphenyl oxide (DBDPO) as a flame retardant,
The nanocomposite resin is formed by extruding an environmentally friendly synthetic wood composition comprising 92 to 95% by weight of polypropylene or polyethylene resin and 5 to 8% by weight of montmorillonite.

상기 목분은 간벌목 자재나(주로 소나무와 같은 침엽수) 폐목자재를 사용하는데, 소나무와 같은 침엽수는 반드시 목재가 함유하고 있는 로진(Rosin) 성분을 사전에 제거하여 사용해야 하며, 통상 100 메쉬(0.14㎜) 내지 120 메쉬(0.117㎜) 크기의 목분을 건조하여 사용한다. The wood powder is used for thinning wood materials (mostly coniferous trees such as pine trees) or waste wood materials, and coniferous trees such as pine trees must be used after removing the rosin component, which is usually contained in wood, and usually 100 mesh (0.14 mm). ) To 120 mesh (0.117 mm) wood flour is used to dry.

상기 목분은 입자 굵기가 100 메쉬(0.14㎜) 미만이면 혼합성에서 좋지 않으며 120 메쉬(0.117㎜)를 초과하면 지나치게 목분이 미세하게 되어 합성목재 고유 강도(휨강도 등)가 잘 나오지 않게 되므로, 목분의 입자 사이즈를 상기의 입자 크기 범위로 유지하는 것이 중요하다. 아울러, 목분의 입자 사이즈가 균일하지 않으면 어느 부분은 잘 섞이고 어느 부분은 잘 섞이지 않는 편중 현상이 발생되므로, 상기한 범위로 목분의 입자 사이즈를 균일하게 유지하는 것이 중요하다.The wood powder is not good in mixing properties when the particle size is less than 100 mesh (0.14㎜), and if the particle size exceeds 120 mesh (0.117㎜), the wood powder becomes too fine and the natural wood natural strength (bending strength, etc.) is hard to come out. It is important to keep the particle size in the above particle size range. In addition, if the particle size of the wood powder is not uniform, some parts are mixed well and some parts are not mixed well, so it is important to maintain the particle size of the wood powder uniformly in the above range.

또한, 상기 목분은 수분 함수율 5% 미만, 바람직하게는 1~3% 범위를 구비하며, 이와 같은 목분의 함수율은 합성수지 또는 나노복합수지와의 결합력을 고려한 것이다.
In addition, the wood flour has a moisture content of less than 5%, preferably in the range of 1 to 3%, the moisture content of such wood powder is to take into account the bonding strength of the synthetic resin or nano composite resin.

상기 매개체로 사용되는 합성수지는 결정성 폴리머로서 인체에 전혀 무해하며 소각을 하더라도 다이옥신과 같은 유해 물질이 전혀 검출되지 않는 환경친화적인 특성을 구비한 폴리에틸렌 또는 폴리프로필렌을 사용하며, 10~30중량%, 보다 바람직하게는 15~28중량%, 가장 바람직하게는 20~25중량%를 첨가한다.
Synthetic resin used as the mediator is a crystalline polymer, which is completely harmless to the human body, and uses polyethylene or polypropylene having environmentally friendly properties such that no harmful substances such as dioxins are detected even when incinerated, and 10 to 30% by weight, More preferably, 15 to 28 weight%, Most preferably, 20 to 25 weight% is added.

상기 나노복합수지는 고분자인 합성수지에 나노 사이즈의 나노복합소재 입자를 박리, 분산시킨 것으로, 폴리프로필렌수지 또는 폴리에틸렌수지에 나노복합소재인 몬모릴로나이트를 첨가하여 나노복합화한 것이다. 이와 같은 본 발명의 나노복합수지는 내충격성, 인성 및 투명성 등의 손상이 없이, 강도, 내마모성, 고온안정성, 난연성 등이 향상된 특성을 구비한다. The nanocomposite resin is obtained by peeling and dispersing nano-sized nanocomposite particles in a synthetic resin, which is a polymer, and nanocomposites by adding montmorillonite, which is a nanocomposite material, to a polypropylene resin or a polyethylene resin. Such a nanocomposite resin of the present invention has improved properties such as strength, wear resistance, high temperature stability, flame retardancy, and the like without damages such as impact resistance, toughness and transparency.

즉, 일반적인 고분자 수지의 경우 난연특성을 보강하기 위해 난연제를 단순히 혼합하게 되는데, 이 경우 고분자 수지 자체의 기계적 물성을 저하시키는 결과를 초래하므로 단순 컴파운딩에서 벗어나 기계적 물성과 난연특성을 동시에 향상시키기 위하여 본 발명은 나노복합수지를 사용한다.In other words, in the case of general polymer resins, flame retardants are simply mixed to reinforce the flame retardant properties. In this case, the mechanical properties of the polymer resins are reduced. The present invention uses a nano composite resin.

상기 나노복합수지는 합성수지 92~95중량%에, 무기질 나노입자인 몬모릴로나이트 5~8중량%를 첨가하여 형성한다. 상기 나노복합수지는 일예로 합성수지와 몬모릴로나이트를 배합기와 이축압출기를 사용하여 용융혼합법으로 형성하며, 이때, 상용화제로 무수말레인산이 그래프트된 폴리프로필렌 또는 폴리에틸렌을 더 첨가할 수 있다. The nanocomposite resin is formed by adding 5 to 8% by weight of montmorillonite, which is an inorganic nanoparticle, to 92 to 95% by weight of synthetic resin. For example, the nano-composite resin is formed by melt mixing using synthetic resin and montmorillonite using a blender and a twin screw extruder. In this case, polypropylene or polyethylene grafted with maleic anhydride may be further added as a compatibilizer.

상기 몬모릴로나이트는 판상 실리케이트 구조인 몬모릴로나이트로, 몬모릴로나이트 또는, 층간에 있는 금속이온을 암모늄이나 포스포튬 이온을 포함하는 유기화제 또는 알킬암모늄 염으로 치환시킨 개질 몬모릴로나이트를 사용한다. The montmorillonite is montmorillonite having a plate-silicate structure, montmorillonite, or modified montmorillonite in which metal ions in the interlayers are substituted with an organic agent or alkylammonium salt containing ammonium or phosphonium ions.

또한, 상기 나노복합수지는 합성수지 및 몬모릴로나이트를 투입하고, 이를 배합기를 사용하여 150~220℃의 온도조건에서 220~300rpm으로 혼련하고, 이축압출기를 이용하여 스트랜드 커팅(strand cutting)방식으로 펠렛화할 수 있다.
In addition, the nano-composite resin is added to the synthetic resin and montmorillonite, and kneaded at 220 ~ 300rpm at a temperature condition of 150 ~ 220 ℃ using a compounding machine, it can be pelletized by the strand cutting method using a twin screw extruder have.

상기와 같이 이루어진 본 발명에 따른 나노복합수지는 연소시, 고분자 수지인 합성수지는 연소되지만, 무기입자인 몬모릴로나이트는 연소되지 않고, 표면에 축적되어 합성목재의 표면에 장벽(barrier)가 형성되게 되며, 이로 인해 외부로부터 산소공급과 열전달이 차단되어 고분자 수지 및 목분이 연소되는 것을 방해하여 향상된 난연특성을 구비하게 된다. When the nanocomposite resin according to the present invention made as described above is combusted, the synthetic resin, which is a polymer resin, is combusted, but montmorillonite, which is an inorganic particle, is not combusted, and accumulates on the surface to form a barrier on the surface of the synthetic wood. As a result, the oxygen supply and heat transfer are blocked from the outside, thereby preventing the polymer resin and the wood powder from burning, thereby providing improved flame retardancy.

또한, 상기 나노복합수지는 그 자체에도 우수한 난연성을 구비하고 있으나, 별도의 난연제를 첨가하여 합성목재를 성형할 경우, 일반적인 난연제의 첨가에 따른 난연성에 비해, 약 2~3배 향상된 난연특성을 구비하는 특성을 구비하게 된다.
In addition, the nanocomposite resin itself has excellent flame retardancy, but when forming a synthetic wood by adding a separate flame retardant, it has about two to three times improved flame retardancy compared to the flame retardancy according to the addition of a common flame retardant It is equipped with the characteristic to make.

상기 탄산칼슘은 수분의 침투를 방지하고, 표면 활성효과를 높여서 치수안정(수축 변화 방지) 효율 높이는 기능 및, 합성목재의 제조시 성형성을 현저하게 개선시키는 기능을 부여하며, 합성목재의 충격강도, 굽힘강도, 열변형 온도 및 하중에 의한 장기적인 변형을 개선시킨다.
