Description
도 1은 본 발명에 따르는 난연성 섬유판재의 일 실시태양을 예시한 개략적인 단면도이다. 1 is a schematic cross-sectional view illustrating one embodiment of a flame retardant fibrous board material according to the present invention.
본 발명은 난연성 섬유판재에 관한 것으로서, 보다 구체적으로는 벤토나이트와 난연제의 혼합물이 함침된 견면과 비함침 견면이 결합된 난연성 폴리에스테르 섬유 판재에 관한 것이다. The present invention relates to a flame retardant fibrous sheet, and more particularly to a flame retardant polyester fiber sheet in which a mixture of bentonite and a flame retardant is impregnated with a cotton plus an impregnated cotton.
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 building 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, but these boards are known to emit substances harmful to the human body and cannot be recycled. 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, 폴리에스테르, 나일론 등의 화학섬유를 10mm 이상으로 절단하여 소면기에 넣어 만든 웹(web)을 가열실에서 일정시간 가열한 후 절단하여 압압판으로 화섬판재가 제시된다. 그러나 이 방법은 화섬물을 10mm 정도의 단섬유로 절단함으로써 단섬유들 간의 엉킴이 적어 잘 부서지는 단점이 있는 것이다. 또한 이러한 판재는 화재시 연기 및 유해가스의 발생으로 인하여 건축내장재로서 부적합한 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 pulverized finely, and a web made by cutting a chemical fiber such as acrylic, polyester, and nylon to 10 mm or more and heating it into a carding machine is heated. After heating for a period of time in the chamber, the cut sheet is presented by a pressed plate. However, this method has the disadvantage of breaking the sapphire into short fibers of about 10 mm, so that there is less tangle between the short fibers. In addition, such a board is not suitable as a building interior material due to the generation of smoke and harmful gases in the fire.
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. 또한 이러한 판재는 화재시 연기 및 유해가스의 발생으로 인하여 건축내장재로서 부적합한 것이다.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. In addition, such a board is not suitable as a building interior material due to the generation of smoke and harmful gases in the fire.
이러한 문제점을 해소하기 위하여 일반 폴리에스테르 섬유와 저융점 폴리에스테르 섬유로 이루어진 웹을 융착하여 폴리에스터 섬유판재를 제조하는 방법이 개발되어 있다. 그러나, 이러한 폴리에스터 섬유판재는 보온성, 단열성, 충격흡수성, 탄성, 외관 등 건축내장재로서 매우 적합한 것이나, 화재시 방염성에 문제가 있는 것이다. In order to solve this problem, a method of manufacturing a polyester fiber board material by fusing a web made of general polyester fiber and low melting point polyester fiber has been developed. However, the polyester fiberboard is very suitable as a building interior material such as insulation, heat insulation, shock absorption, elasticity, and appearance, but has a problem in flame retardancy in fire.
상기한 문제점을 해소하기 위해서 개발된 본 발명자의 대한민국특허 제10-485138호 공보에는 벤토나이트와 방염제를 혼합한 혼합물과 물을 부피기준 0.5~4:1의 비율로 혼합하여서 된 조성물을 도포하여 난연성을 부여한 섬유판재가 기술되어 있다. 이러한 섬유판재는 벤토나이트/방염제 혼합물이 난연성은 충족시키나 상기 혼합물이 판재의 전표면에 피복되어 있어서 섬유 판재 고유의 장점인 미려한 외관을 손상시키고 또한 탄성 또한 손상시키는 등의 문제점이 있어 건축 내장재로서 적용하기에는 다소 부적합한 것이다. Korean Patent No. 10-485138 Publication of the present inventors developed to solve the above problems is a flame retardancy by applying a composition obtained by mixing a mixture of bentonite and flame retardant and water in a ratio of 0.5 to 4: 1 by volume The fibreboard material provided is described. The fibreboard has a problem that the bentonite / flame retardant mixture satisfies the flame retardancy, but the mixture is coated on the entire surface of the slab, thereby impairing the beautiful appearance and elasticity of the fiberboard. It is somewhat inappropriate.
따라서 본 발명은 상기한 선행기술의 문제점을 감안하여 난연성이 우수할 뿐만아니라 벤토나이트/난연재의 함침되어 있음에도 불구하고 우수한 외관성 및 탄성을 보유하여 건축내장재로서 적용하기에 적합한 난연성 섬유판재를 제공하는 것을 목적으로 한다. Therefore, the present invention is not only excellent flame retardancy in view of the above problems of the prior art, but also provides a flame retardant fiberboard material suitable for application as a building interior material having excellent appearance and elasticity despite being impregnated with bentonite / flame retardant The purpose.
상기한 목적을 달성하기 위한 연구에서 벤토나이트가 열을 받으면 팽창하는 특성이 있다는 점에 착안하여 벤토나이트/난연제 혼합물이 함침된 폴리에스테르 견면과 상기 혼합물이 함침되지 않은 견면을 적층한 상태에서 이들을 니들펀칭하여 일체화시킨 섬유판재의 난연성을 테스트한 결과, 상기 혼합물 함침 견면에 함침된 벤토나이트가 열팽창하여 상기 혼합물이 함침되지 않은 견면에도 난연성을 부여하게 된다는 매우 흥미있는 사실을 발견하여 본 발명을 완성하게 된 것이다. In view of the above object, in view of the fact that bentonite expands when it is heated, it is needle-punched in a state in which a polyester pluse impregnated with a bentonite / flame retardant mixture and a plush non-impregnated plush are laminated. As a result of testing the flame retardancy of the integrated fiberboard material, the present invention was completed by discovering a very interesting fact that bentonite impregnated in the mixture impregnated cotton gives thermal expansion to the non-impregnated cotton.
그러므로 본 발명에 의하면 벤토나이트/난연제 혼합물이 함침된 적어도 하나의 폴리에스테르 견면과 상기 혼합물이 함침되지 않은 견면이 니들펀칭에 의해 일체로 적층된 것임을 특징으로 하는 난연성 폴리에스테르 섬유판재가 제공된다. The present invention therefore provides a flame retardant polyester fiberboard material characterized in that at least one polyester plush impregnated with the bentonite / flame retardant mixture and the plush plush impregnated are integrally laminated by needle punching.
이하, 본 발명을 보다 상세하게 설명하기로 한다. Hereinafter, the present invention will be described in more detail.
본 발명에 따르는 난연성 폴리에스테르 섬유판재는 벤토나이트/난연제 혼합물이 함침된 폴리에스테르 견면(이하, '함침 폴리에스테르 견면'이라 약칭하기도 합니다.)과 상기 혼합물이 함침되지 않은 폴리에스테르 견면(이하, '비함침 폴리에스테르 견면'이라 약칭하기도 합니다.)으로 이루어진다. 상기 함침 폴리에스테르 견면과 상기 비함침 폴리에스테르 견면은 니들펀칭에 의해 적층되어 일체화된다. The flame retardant polyester fiberboard according to the present invention is a polyester plush impregnated with a bentonite / flame retardant mixture (hereinafter also abbreviated as 'impregnated polyester plush') and a polyester plush (hereinafter referred to as 'non-impregnated') Impregnated polyester plush. '). The impregnated polyester plush and the non-impregnated polyester plush are laminated and integrated by needle punching.
본 발명에 사용되는 폴리에스테르 견면은 일반 폴리에스테르 섬유인 폴리에틸렌테레프탈레이트 섬유만으로 이루어지거나 또는 일반 폴리에스테르 섬유와 이보다 저융점의 폴리에스테르 섬유를 혼합하여 구성할 수도 있다. 이러한 섬유로 견면을 제조하는 방법은 전자의 경우에는 장섬유 또는 단섬유로 되는 웹 또는 웹적층물을 니들 펀칭하는 것에 의해 제조할 수 있고, 후자의 경우에는 상기 혼합섬유의 장섬유 또는 단섬유로 되는 웹 또는 웹적층물을 열융착시키거나 또는 니들펀칭하는 것에 의해 제조할 수 있다. 이 중에서 특히 바람직한 것은 폴리에틸렌테레프탈레이트 섬유만으로 된 웹 또는 웹적층물을 니들펀칭하여 제조한 견면이다. The polyester plush used in the present invention may be composed of polyethylene terephthalate fibers, which are general polyester fibers, or may be formed by mixing ordinary polyester fibers with polyester fibers having a lower melting point. In the case of the former, the method of manufacturing the plush can be prepared by needle punching a web or a web laminate made of long fibers or short fibers in the former case, and in the latter case, the long fibers or short fibers of the mixed fibers. It can be produced by heat fusion or needle punching the web or web laminate. Particularly preferred among these is a plush prepared by needle punching a web or web laminate made of polyethylene terephthalate fibers only.
본 발명의 섬유판재는 건축내장재로 적용시 비함침 폴리에스테르 견면 부분 이 내장재의 외표면이 된다. 따라서 그 자체만으로도 외관이 우수하나 보다 미려한 외관을 위해서는 비함침 폴리에스테르 견면의 일면에 장식용 원단을 적층구성하여도 된다. In the fiberboard of the present invention, when applied as a building interior material, the non-impregnated polyester shoulder portion becomes the outer surface of the interior material. Therefore, the appearance alone is excellent, but for a more beautiful appearance, a decorative fabric may be laminated on one surface of the non-impregnated polyester plush surface.
상기한 바와 같은 함침 및 비함침 폴리에스테르 견면이 니들펀칭에 의해 적층된 본 발명의 섬유판재에 있어서, 각 구성 견면의 결합개수는 비함침 폴리에스테르 견면 1개당 함침 폴리에스테르 견면 1 또는 2 이상이 적당하다. 2 이상의 함침 견면이 사용되는 경우에는 함침 견면들이 인접하도록 구성시켜야 하는데, 그 이유는 섬유판재의 일 표면이 비함침 폴리에스테르 견면이어야 건축 내장재로서 적합한 외관, 탄성 등을 발현할 수 있기 때문이다. 도 1은 본 발명에 따르는 섬유판재의 일 실시구현을 예시한 것으로 인접하여 적층된 제 1 및 제 2 함침 폴리에스테르 견면(1,2)과 상기 제 2 함침 폴리에스테르 견면위에 비함침 폴리에스테르 견면(3)이 적층된 구조를 나타낸 것이다.In the fiberboard material of the present invention in which the impregnated and non-impregnated polyester faces as described above are laminated by needle punching, the number of bonds of each component of the impregnated polyester faces is suitably one or two or more impregnated polyester faces per one impregnated polyester face. Do. When two or more impregnated plushs are used, the impregnated plushs should be configured to be adjacent to each other, because one surface of the fiberboard material must have an unimpregnated polyester plush so that the appearance, elasticity, etc., suitable for building interior materials can be expressed. 1 illustrates an embodiment of a fibrous sheet material according to the present invention, wherein the first and second impregnated
특별히 제한하기 위한 것은 아니지만 본 발명의 섬유판재에 있어서 비함침 폴리에스테르 견면의 총 두께는 2~10mm의 두께가 적당하다. 비함침 폴리에스테르 견면의 총 두께가 너무 얇으면 섬유판재의 탄성이 다소 미흡하게 되고, 너무 두꺼우면 함침 폴리에스테르 견면에 의한 난연성 발현효과가 높지 않기 때문이다. Although not particularly limited, the total thickness of the non-impregnated polyester shoulder is preferably 2 to 10 mm in the fiberboard of the present invention. If the total thickness of the non-impregnated polyester cotton is too thin, the elasticity of the fiberboard material is somewhat insufficient, and if it is too thick, the effect of developing flame retardancy by the impregnated polyester cotton is not high.
본 발명의 섬유판재는 다양한 두께로 제조하는 것이 가능하지만, 건축내장재의 용도로 바람직한 두께는 7~45mm 정도이다. 또한, 상기한 두께 범위에서 건축내장재에 요구되는 난연2급에 부합하기 위해서는 함침 폴리에스테르 견면층의 두께가 섬유판재 전체 두께의 50~90%가 되도록 하는 것이 바람직하다. The fiberboard material of the present invention can be produced in a variety of thicknesses, the thickness of the preferred for the use of building interior materials is about 7 ~ 45mm. In addition, in order to meet the flame
본 발명에서 있어서, 상기 벤토나이트/난연제 혼합물이 함침된 폴리에스테르 견면은 바람직하게 20~80중량%의 벤토나이트와 80~20중량%의 난연제를 물과 함께 혼합하여 얻은 수성 조성물에 폴리에스테르 견면을 침지시키거나 또는 폴리에스테르 견면에 상기 수성 조성물을 분무한 다음, 건조하는 것에 의해 제조될 수 있다. 특별히 제한하기 위한 것은 아니지만 상기 수성조성물의 수분함량은 30~95중량%가 적당한데, 그 주된 이유는 견면에 벤토나이트와 난연제 균일한 혼합 및 얻어진 혼합물의 용이한 함침에 있다. In the present invention, the polyester cotton impregnated with the bentonite / flame retardant mixture is preferably immersed in the aqueous composition obtained by mixing 20 to 80 wt% bentonite and 80 to 20 wt% flame retardant with water. Or by spraying the aqueous composition on polyester cotton and then drying. Although not particularly limited, the water content of the aqueous composition is suitably 30 to 95% by weight, mainly because of the uniform mixing of bentonite and flame retardant on the surface and the easy impregnation of the obtained mixture.
본 발명의 섬유판재에 함침된 벤토나이트/난연제 혼합물은 난연제 주위에 벤토나이트가 에워 싸 있는 입자형태를 유지하여 비화재시 난연제의 방출을 효과적으로 차단하고 흡음효과를 제공하나, 화재시에는 벤토나이트가 열팽창하면서 1차적으로 불의 번짐을 차단하고 2차적으로는 벤토나이트 속의 난연제가 터져나와 소화작용을 하게 된다. The bentonite / flame retardant mixture impregnated in the fiberboard of the present invention maintains the particle form surrounded by bentonite around the flame retardant to effectively block the release of the flame retardant during incombustibility and provide sound absorption effect, but in the event of fire 1 Secondly, it prevents the spread of fire, and secondly, the flame retardant in the bentonite explodes to be digested.
본 발명에서 난연제로는 유기계 난연제와 무기계 난연제 모두 사용할 수 있다. 난연제는 구성성분에 따라 유기계와 무기계로 분류되며, 유기계는 주로 인산계, 브롬계 및 염소계를 포함하는 할로겐계로 분류되고, 상기 할로겐계 난연제로서는 테트라브로모비스페놀 A, 헥사플루오로벤젠, 데카브로모디페닐옥사이드, 염화파라핀 등이 있다. 무기계로는 수산화알루미늄계, 안티몬계, 수산화마그네슘계, 산화주석, 수산화지르코늄, 메타붕산바륨 등으로 분류된다. 상기 할로겐 또는 인을 함유하지 않은 난연제로는 실리콘 화합물이 알려져 있다. 또한, 인계 난연제 또는 금 속 수산화물로 이루어진 무기계 난연제 및 난연조제로서, 산화안티몬, 멜라민 화합물을 단독 또는 조합해서 사용할 수도 있다. 바람직하기로는 수용성 난연제이며, 특히 수용성 나노 난연제이다. 이러한 수용성 나노 난연제의 예로는 카르복실산 유도체를 함유하는 인계 난연제를 금속산화물이 전기분해되어 나노입자크기로 생성된 무기계 난연제에 결합시킨 수용성 난연제가 있다As the flame retardant in the present invention, both organic and inorganic flame retardants may be used. Flame retardants are classified into organic and inorganic based on their components, and organic is mainly classified into halogens including phosphoric acid, bromine and chlorine. Phenyl oxide, paraffin chloride, and the like. The inorganic type is classified into aluminum hydroxide type, antimony type, magnesium hydroxide type, tin oxide, zirconium hydroxide, barium metaborate and the like. Silicone compounds are known as flame retardants that do not contain halogen or phosphorus. Moreover, as an inorganic flame retardant and a flame retardant adjuvant which consist of a phosphorus flame retardant or a metal hydroxide, antimony oxide and a melamine compound can also be used individually or in combination. Preferably it is a water soluble flame retardant, especially a water soluble nano flame retardant. An example of such a water-soluble nano flame retardant is a water-soluble flame retardant in which a phosphorus flame retardant containing a carboxylic acid derivative is bonded to an inorganic flame retardant produced by electrolysis of a metal oxide to a nanoparticle size.
이상 설명한 바와 같이 벤토나이트/난연제 혼합물이 함침된 폴리에스테르 견면과 상기 혼합물이 함침되지 않은 견면이 니들펀칭에 의해 적층된 구조를 갖는 본 발명의 난연성 섬유판재는 통상의 섬유판재 고유의 장점인 우수한 탄성과 미려한 외관을 보유하면서도 화재시에는 벤토나이트/난연제 함침 견면의 벤토나이트가 열팽창하여 상기 혼합물이 함침되지 않은 견면에도 난연성을 부여함으로써 난연2급과 탄성 및 미려한 외관이 요구되는 건축내장재로 매우 유용하게 적용할 수 있다. As described above, the flame retardant fibrous sheet of the present invention having a structure in which a polyester plush impregnated with a bentonite / flame retardant mixture and a non-impregnated plush layer is laminated by needle punching has excellent elasticity, which is inherent in conventional fiberboard materials. Bentonite / flame retardant impregnated cotton bentonite is thermally expanded in case of fire while giving a beautiful appearance to impart flame retardancy to the surface without the mixture impregnated, so it can be very useful as a building interior material that requires second class flame retardancy and elasticity and beautiful appearance. have.
