Description
본 발명은 섬유 판재에 관한 것으로서, 특히 건축용 내·외장재, 침구류용,가구용 및 기타 산업용도에 사용하고 있는 하드보드, 석고보드, 암면 등을 대용할 수 있으며, 재활용이 가능하고 단열성 및 흡음성이 우수한 폴리에스테르 섬유 판재 및 그 제조방법에 관한 것이다.The present invention relates to a fiber board material, in particular can replace the hard board, gypsum board, rock wool and the like used in the interior and exterior materials for building, bedding, furniture and other industrial applications, it is recyclable and excellent insulation and sound absorption Polyester fiber board | plate material and its manufacturing method.
건축자재 및 산업용 자재 등에는 주로 암면, 석고보드, 유리섬유, 스티로폴 등 단열재와 압축목재와 접착제로 구성된 하드보드 등이 사용되고 있으나, 이러한 판재들은 인체에 유해한 물질을 배출하는 것으로 알려져 있으며 또한 재활용이 불가능하여 환경공해를 일으키는 등의 문제점이 있다.In construction materials and industrial materials, rock wool, gypsum board, glass fiber, styropol, etc. are mainly used as insulation materials and hard boards composed of compressed wood and adhesives. There is a problem such as causing environmental pollution.
종래 폐화섬물로 판재를 제조하는 방법이 알려져 있다. 예를 들어 한국공개 특허공보 공고 87-5764호에 의하면, 섬유상의 폴리프로필렌을 잘게 분쇄하고 이에 아크릴, 폴리에스터, 나이론 등의 화학섬유를 10mm 이상으로 절단하여 소면기에 넣어 만든 웹(web)을 가열실에서 일정시간 가열한 후 절단하여 압압판으로 압착성형한 화섬판재가 제시된다. 그러나 이 방법은 화섬물을 10mm 정도의 담섬유로 절단함으로써 단섬유들 간의 엉킴이 적어 잘 부서지는 단점이 있는 것이다.BACKGROUND OF THE INVENTION A method of manufacturing a plate material from waste islands is known. For example, according to Korean Patent Publication No. 87-5764, a fibrous polypropylene is finely pulverized, and a web made by cutting a chemical fiber such as acrylic, polyester, and nylon to 10 mm or more is heated in a carding machine. It is presented a fiber board material which is heated in a chamber for a certain time, cut and press-molded with a press plate. However, this method has the disadvantage of breaking the sapphire into 10mm bile fibers so that the entanglement between the short fibers is small and breaks well.
또한 한국 특허 공보 공고 95-6863호에 의하면 폐화섬물을 50∼100 mm 정도의 장섬유로 절단하여 타면기에서 타면하여 솜상태로 하고 이를 일정두께의 매트형태로 한 다음 이들을 적당한 두께의 층으로 적층하여 섬유실 끼리 서로 일체가 되도록 고열화 고압으로 가열가압함으로써 화섬판재를 제조하는 방법이 알려져 있다. 그러나 상기한 방법으로 제조한 화섬판재는 고온 및 고압에서 성형되므로 섬유구성물질인 고분자 물질의 분해를 초래하게 되고 섬유의 고유특성이 상실되는 문제점이 있는 것이다. 또한 상기한 종래의 방법들은 폐화섬물을 이용하기 때문에 작업환경이 불량하고 환경공해물질을 발생시키는 문제점을 안고 있는 것이기도 하다.In addition, according to Korean Patent Publication No. 95-6863, the waste islands are cut into 50 to 100 mm long fibers, which are then spun on the other side of the machine to form a cotton mat, and then they are laminated in a certain thickness. There is known a method of producing a fiber board material by heating and pressing at high deterioration and high pressure so that the fiber chambers are integrated with each other. However, the fiber sheet produced by the above method is molded at high temperature and high pressure, which causes the decomposition of the polymer material, which is a fiber constituent, and the inherent properties of the fiber are lost. In addition, the above-mentioned conventional methods also have a problem in that the working environment is poor and environmental pollutants are generated because they use waste islands.
따라서 본 발명은 섬유의 고유특성을 유지하면서 물성이 우수한 새로운 섬유판재를 제공하는 것을 과제로 한다.Accordingly, an object of the present invention is to provide a new fibrous sheet having excellent physical properties while maintaining the intrinsic properties of the fibers.
상기한 과제를 해결하기 위한 연구에서 본 발명자는 저융점 폴리에스테르 섬유와 고융점 폴리에스테르 섬유가 혼합된 웹을 저온압축하게 되면 섬유의 형태를 그대로 유지함으로써 섬유 사이에 미세공기층을 포함하게 되고 이에 의해 우수한 단열 및 흡음효과를 제공하며 기계적 물성 또한 우수하고 재활용이 가능하여 건축 및 산업용 자재로 매우 유용하게 된다는 사실을 알게 되어 본 발명을 완성하게 된 것이다.In the research for solving the above problems, the inventors of the present invention, when the low-melting polyester fibers and the high-melting polyester fibers are mixed at low temperature, the microfiber layer is included between the fibers by maintaining the shape of the fibers as they are. The present invention has been completed by providing the excellent thermal insulation and sound absorption effect and excellent mechanical properties and recyclability, which makes it very useful for building and industrial materials.

Provided is a method for producing a polyester fiber sheet comprising a.
이하 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 섬유판재는 고융점 폴리에스테르 섬유의 물성을 그대로 유지하면서 섬유간의 엉킴과 저융점 폴리에스테르가 결합제 역할을 하여 0.15∼0.45g/㎤의 밀도와 1.0∼4.0N/㎟의 휨강도를 유지하도록 성형된다.본 섬유판재의 밀도가 0.15g/㎤ 보다 낮으면 기공이 너무 커져 단열성 및 흡음성이 불량하게 되고, 0.45g/㎤ 보다 낮으면 미세기공의 형성이 미흡하여 이 또한 단열성 및 흡음성 불량의 원인이 될 수 있다. 또한 휨강도가 1.0N/㎟ 보다 낮으면 형태유지성이 불량하여 시공하기가 곤란하게 되며, 4.0N/㎟ 보다 높으면 시공벽면에 대한 밀착성이 불량하게 되어 단열 및 흡음효과의 저하를 초래할 수 있어 바람직하지 못하다.The fiber board material of the present invention is to maintain the physical properties of the high-melting polyester fibers intact, so that the entanglement between the fibers and the low-melting polyester acts as a binder to maintain a density of 0.15 to 0.45 g / cm 3 and a bending strength of 1.0 to 4.0 N / mm 2 If the density of this fiberboard material is lower than 0.15 g / cm 3, the pores become too large, resulting in poor thermal insulation and sound absorption, and if lower than 0.45 g / cm 3, the formation of micropores is insufficient, which is also a cause of poor thermal insulation and sound absorption. This can be In addition, when the flexural strength is lower than 1.0 N / mm 2, it is difficult to install due to poor shape retention. When the flexural strength is higher than 4.0 N / mm 2, the adhesion to the construction wall surface becomes poor, which may lead to a decrease in thermal insulation and sound absorption effects. .
이를 위하여 본 발명에서는 원료섬유로서 저융점 폴리에스테르 섬유와 고융점 폴리에스테르 섬유를 사용한다. 저융점 폴리에스테르 섬유와 고융점 폴리에스테르 섬유의 융점차이는 50℃ 이상, 바람직하게 80℃ 이상, 특히 100℃ 이상이 적당하다. 저융점 폴리에스테르 섬유와 고융점 폴리에스테르 섬유의 융점차이가 50℃ 보다 적은 경우에는 융착시에 고융점 섬유가 형태변형을 일으키기 쉬우며, 이러한 경우 미세기공층 형성이 불량하게 되어 결과적으로 단열 및 흡음성이 불량하게 된다.To this end, the present invention uses a low melting point polyester fiber and a high melting point polyester fiber as the raw material fibers. The melting point difference between the low melting polyester fiber and the high melting polyester fiber is 50 ° C or higher, preferably 80 ° C or higher, particularly 100 ° C or higher. If the melting point difference between the low-melting polyester fiber and the high-melting polyester fiber is less than 50 ° C, the high-melting fiber tends to cause morphological deformation during fusion, in which case the formation of the microporous layer becomes poor, resulting in thermal insulation and sound absorption. This becomes bad.
저융점 폴리에스테르의 예로는 지방족 디올과 탄소수 4 이상의 지방족 디카르복실산의 중합 생성물; 지방족 디올, 탄소수 4 이상의 지방족 디카르복실산 및 방향족 디카르복실산의 공중합 생성물 등이 있다. 고융점 폴리에스테르의 예로는 지방족 디올과 방향족 디카르복실산의 중합생성물(예: 폴리에틸렌테레프탈레이트) 등이 있다.Examples of low melting polyesters include polymerization products of aliphatic diols and aliphatic dicarboxylic acids having at least 4 carbon atoms; And copolymerized products of aliphatic diols, aliphatic dicarboxylic acids having 4 or more carbon atoms, and aromatic dicarboxylic acids. Examples of high melting point polyesters include polymerization products of aliphatic diols and aromatic dicarboxylic acids (eg, polyethylene terephthalate).
저융점 섬유와 고융점 섬유의 혼합비율은 고융점 성분을 50중량% 이상(바람직하게 50∼90중량%)으로 하고 저융점 성분을 50중량% 이하(바람직하게 10∼50중량%)로 한다. 고융점 섬유의 함량이 90%를 초과하고 저융점 섬유의 함량이 10% 미만인 경우에는 융착불량이 일어날 수 있으며, 그 반대로 고융점 섬유의 함량이 50중량% 미만이고 저융점 섬유의 함량이 50중량%를 초과하는 경우에는 미세기공층이 적게 형성되어 그 결과 단열 및 흡음성이 불량하게 될 수 있다.고융점 섬유와 저융점 섬유는 그 섬도가 서로 같거나 또는 다른 것을 사용할 수도 있고, 여러 가지 섬도의 것을 혼합하여 사용할 수도 있다. 바람직한 섬도 범위는 2∼30 데니어가 적당하다.The mixing ratio of the low melting point fiber and the high melting point fiber is 50 wt% or more (preferably 50 to 90 wt%) of the high melting point component and 50 wt% or less (preferably 10 to 50 wt%) of the low melting point component. When the content of the high melting fiber exceeds 90% and the content of the low melting fiber is less than 10%, fusion defect may occur. In contrast, the content of the high melting fiber is less than 50% by weight and the content of the low melting fiber is 50% by weight. If it exceeds%, the microporous layer may be less formed, resulting in poor insulation and sound absorption. The high melting point fibers and the low melting point fibers may have the same or different fineness, and may have different fineness. You may use it, mixing it. Preferable fineness range is 2-30 denier.
고융점 섬유의 섬유형태 및 물성을 유지시키기 위해서 본 발명에서는 저온융착방식이 적용된다. 특별히 제한하기 위한 것은 아니지만, 이러한 방식의 일예로서 고융점 폴리에스테르 섬유의 융점 이하의 온도를 갖는 열풍으로 예열하고 냉각압축롤러로 냉각압축하는 예열-냉각압축공정을 다단계로 수행한 후, 성형냉각하는 방식을 들 수 있다. 상기한 방식의 경우, 열풍온도는 120∼200℃에서 조절하고, 냉각압축 및 성형냉각시의 온도는 5℃ 이하에서 조절하는 것이 바람직하다.In order to maintain the fiber form and physical properties of the high melting point fibers, the low temperature fusion method is applied in the present invention. Although not particularly limited, as an example of such a method, after preheating-cooling compression step of preheating with hot air having a temperature below the melting point of the high-melting point polyester fiber and cooling with a cold compression roller in a multi-step, The way is. In the case of the above-described method, the hot air temperature is adjusted at 120 to 200 ° C, and the temperature at the time of cooling compression and molding cooling is preferably controlled at 5 ° C or lower.
