Abstract
본 발명은 목분을 이용한 건축내장재에 관한 것으로 좀더 상세히는 방음재 또는 단열재로 쓰이는 비드형 범용 발포체인 EPS(expandable polystyrene) 또는 EPP(expandable polypropylene)와 목분, 액상수지, 난연제를 혼합, 성형하여 제조되는 비중이 0.05~0.2인 난연성 건축내장재에 관한 것이다.The present invention relates to building interior materials using wood powder, more specifically, specific gravity produced by mixing and molding bead-type general-purpose foam (expandable polystyrene) or EPP (expandable polypropylene) and wood flour, liquid resin, and flame retardant which are used as sound insulation or insulation. It is about flame retardant building interior materials of 0.05-0.2.
Description
본 발명은 목분을 이용한 건축내장재에 관한 것으로 좀더 상세히는 방음재 또는 단열재로 쓰이는 비드형 범용 발포체인 EPS(expandable polystyrene) 또는 EPP(expandable polypropylene)와 목분, 액상수지, 난연제를 혼합, 성형하여 제조되는 비중이 0.05~0.2인 난연성 건축내장재에 관한 것이다. 본 발명의 건축자재는 EPP 또는 EPS의 특성인 경량성 및 단열성과 함께 목분을 함유하여 친환경적이며 강도를 높일 수 있는 장점이 있다.The present invention relates to building interior materials using wood powder, more specifically, specific gravity produced by mixing and molding bead-type general-purpose foam (expandable polystyrene) or EPP (expandable polypropylene) and wood flour, liquid resin, and flame retardant which are used as sound insulation or insulation. It is about flame retardant building interior materials of 0.05-0.2. The building material of the present invention has the advantage of being environmentally friendly and increasing the strength by containing wood powder together with light weight and heat insulation properties of EPP or EPS.
방음, 방염 및 단열 등을 위하여 일반적으로 사용되는 건축내장재로는 비중이 낮은 스티로폼, 글라스울 또는 우레탄 폼 등이 있다. Building interior materials generally used for soundproofing, flame retardant, and thermal insulation include low-specification styrofoam, glass wool or urethane foam.
스티로폼인 발포폴리스티렌(Expandable Polystyrene; EPS)은 폴리스티렌 수지에 펜탄(Pantane : C5H12)이나 부탄과 같은 발포제를 첨가시켜 가열 경화시킴과 동시에 기포를 발생시켜 발포수지로 만든 것으로서 스티렌모노머(Styrene Monomer : C8H8)를 중합시켜 제조한다. 스티로폴은 발포제를 함유하고 있는 스티렌 중합체 또는 공중합체로서 종류에 따라 직경 0.2㎜~0.3㎜의 비드(bead)나 길이 약 2.5㎜, 직경 약 0.6㎜인 원주형 펠렛(pellet) 상태로 공급된다. 스티로폴 제품은 태양광선에 장시간 노출될 경우 색이 노랗게 변하며 표면이 부스러지게되는 경향이 있으나 직접 외기와 접촉하지 않는 한 물리적 특성은 전혀 변화가 없다.Styrofoam (Expandable Polystyrene; EPS) is made of foamed resin by adding foaming agents such as pentane (C 5 H 12 ) or butane to the polystyrene resin to generate heat and at the same time to generate air bubbles. : Prepared by polymerization of C 8 H 8 ). Styropol is a styrene polymer or copolymer containing a blowing agent, and is supplied in the form of beads having a diameter of 0.2 mm to 0.3 mm or cylindrical pellets having a length of about 2.5 mm and a diameter of about 0.6 mm depending on the type. Styropol products tend to turn yellow and deteriorate after prolonged exposure to sunlight, but physical properties remain unchanged unless they are in direct contact with outside air.
또한, EPS와 함께 많이 사용되는 EPP는 발포폴리프로필렌(Expanded Polypropylene)이라 하며 원료인 폴리프로필렌(polypropylene) 수지의 특성상 EPS보다 깨짐성, 반복 완충성, 유연성 및 내약품성 등이 우수하여 제품포장의 안정성 향상 및 포장 부피 소형화에 장점이 있어, 주로 전자제품 포장, 자동차 부품 및 구조물 등에 적용되고 있다. 최근에는 EPS의 환경문제로 인한 각국의 규제 조치가 실행되어 플라스틱 계통의 대체 제품으로 EPP 적용이 늘고 있는 경향이다. In addition, EPP, which is widely used together with EPS, is called expanded polypropylene and is more stable than the EPS due to the characteristics of polypropylene resin, which is excellent in breaking, repeat buffering, flexibility and chemical resistance. There is an advantage in improving and miniaturizing the packaging volume, mainly applied to the packaging of electronic products, automobile parts and structures. In recent years, regulatory measures have been implemented in each country due to the environmental problems of EPS, which has led to an increase in the application of EPP as a substitute for plastics.
또한, 최근에는 합성수지나 합성목재 발포체 등의 사용이 두드러지고 있다. 합성수지에 발포제를 투입하여 발포하는 경우 비중이 0.7 정도이나, 목분이나 광물질 등의 충전재를 다량 함유하게 되면 0.85-0.9의 비중을 갖게 되어 경량화에 한계를 갖게 된다. 이는 대부분의 제품들이 펠렛형의 고분자 수지를 고온에서 용융시킨 후 목분과 혼합하고 고체 난연제를 사용하므로 발생하는 것이다.In recent years, the use of synthetic resins, synthetic wooden foams and the like has become prominent. When the foaming agent is added to the synthetic resin and foamed, the specific gravity is about 0.7, but if it contains a large amount of filler such as wood powder or minerals, the specific gravity is 0.85-0.9, which limits the weight reduction. This occurs because most products melt pelletized polymer resin at high temperature, mix it with wood powder, and use a solid flame retardant.
대한민국 특허공개 제2001-34724호는 고분자수지와 섬유의 복합재를 발포시켜 제조한 건축내장재에 관한 것으로 펠렛형의 고분자 수지를 용융시켜 용융된 수지 내로 발포제나 발포가스를 도입시켜 발포한 것으로 비중이 1.2g/cc로써 일반제품에 비하여 10% 가량 가볍다고 기재하고 있다. 그러나 목분이나 기타의 충전재가 첨가될 경우에는 발포를 저해하는 요인으로 작용하여 원하는 비중을 얻기 어렵다. 대한민국 특허공개 제2000-49620호 또한 펠렛형의 합성수지 특히 폴리염화비닐과 목분을 사용하여 압출 발포성형하여 제조한 것으로 상기 특허공개 제2001-34724호와 유사한 방법으로 제조하였다. 또한 대한민국 특허 제0186945호는 폐목죽재와 열가소성 폐합성수지를 혼합 용융하여 압출시 발포제를 첨가하고 발포하여 비중을 감소시키는 제조방법을 기재하고 있다. 폐목죽재 파우더의 진 비중은 1.2 정도이므로 발포제를 투입하더라도 0.9 이하로 비중이 떨어지지 않는다.Korean Patent Laid-Open No. 2001-34724 relates to a building interior material manufactured by foaming a composite of a polymer resin and a fiber, and is formed by melting a pellet-type polymer resin and introducing a foaming agent or a foaming gas into the molten resin to foam. g / cc is about 10% lighter than general products. However, when wood flour or other fillers are added, it acts as a deterrent to foaming, and thus it is difficult to obtain a desired specific gravity. Korean Patent Publication No. 2000-49620 was also prepared by extrusion foam molding using pellet-type synthetic resin, in particular polyvinyl chloride and wood flour, and was prepared by a method similar to Patent Publication No. 2001-34724. In addition, the Republic of Korea Patent No. 0186945 describes a manufacturing method for reducing the specific gravity by mixing and melting the waste wood bamboo material and thermoplastic waste synthetic resin by adding a blowing agent during the extrusion and foaming. Since the specific gravity of the waste wood powder is about 1.2, the specific gravity does not drop below 0.9 even if the blowing agent is added.
상기 발명들은 펠렛형이나 고체형의 합성수지를 용융하고 기타의 첨가제나 충전재를 부가하여 제조한 것으로 목분이나 기타 천연소재, 광물 또는 탄산칼슘을 다량 투입하여 발포할 경우 충전제의 비중이 1.1~1.3 정도이므로 발포제품의 비중이 0.9-0.85 이하로 떨어지는 데는 한계가 있다. 또한 발포를 위하여 첨가되는 발포제의 경우 압출을 통해서만 발포가 이루어지므로 강제로 압력을 가하여 성형하는 방법을 택하고 있어 이 또한 비중을 줄이는데 한계로 작용할 수 있다.The inventions are prepared by melting a pellet or solid synthetic resin and adding other additives or fillers, and the specific gravity of the filler is 1.1-1.3 when foamed by adding a large amount of wood powder or other natural materials, minerals or calcium carbonate. There is a limit to the share of foam products falling below 0.9-0.85. In addition, in the case of the foaming agent added for foaming, the foaming is performed only through extrusion, and thus, a method of forming the foam by forcibly applying pressure may limit the specific gravity.
따라서, 본 발명은 발포체인 EPS(expandable polystyrene) 또는 EPP(expandable polypropylene)과 목분, 난연제 및 액상수지를 혼합하여 강도는 향상되면서 비중이 0.05~0.2로 매우 낮은 경량의 건축내장재를 제공하는 것을 목적으로 한다.Accordingly, an object of the present invention is to provide a lightweight building interior material having a very low specific gravity of 0.05 to 0.2 while improving strength by mixing foam (expandable polystyrene) or EPP (expandable polypropylene) with wood powder, flame retardant and liquid resin. do.

The binder is a non-combustible material of natural ingredients, the main component is SiO 2 , and prevents wood powder from absorbing the liquid resin, thereby reducing the amount of liquid resin added, thereby reducing production costs, and facilitating the dispersion of wood powder. It serves to eliminate the need for such addition. In addition, the coated wood powder is coated with a binder and dried until the moisture content of the wood powder is less than 5% at 70 ~ 100 ℃ to prepare a coated wood powder.
