본 발명은 난연성 건축내장재 및 그 제조방법에 관한 것으로, 보다 상세하게는 방수제와 항균제가 투입된 난연액에 부직포를 함침하여 보오드를 제조하므로서 화재시 유독가스에 의한 인명피해와 화재의 확산을 방지할 수 있게 하고, 또한 보오드에 방수기능과 항균기능 그리고 단열기능과 흡음기능 등이 포함되도록 하여 건축내장재로서 우수한 기능을 갖도록 하며, 또한 보오드 일면에 황토층과 숯층 그리고 황토와 숯을 혼합한 시트층 중 어느 하나를 형성하여 황토에 의한 원적외선 발생과 숯에 의한 유해물질 흡착으로 새집 증후군(비염, 아토피성 피부염, 두드러기, 천식, 두통, 기관지염 등)이 예방될 수 있게 하고, 또한 폐섬유를 활용하여 건축내장재를 제조하므로서 폐섬유를 처리하는 데에 따른 운반비용과 환경오염문제를 일소 시킬 수 있게 한 난연성 건축내장재 및 그 제조방법에 관한 것이다. The present invention relates to a flame-retardant building interior material and a method for manufacturing the same, and more particularly, to prevent the damage of life and the spread of fire by toxic gases by manufacturing a board by impregnating a non-woven fabric in a flame retardant solution containing a waterproofing agent and an antimicrobial agent. In addition, the board includes waterproof function, antibacterial function, heat insulation function and sound absorption function so as to have an excellent function as a building interior material, and also one of the ocher layer and charcoal layer and the sheet layer mixed with ocher and charcoal on one side of the board. To prevent the sick house syndrome (rhinitis, atopic dermatitis, urticaria, asthma, headache, bronchitis, etc.) by generating far-infrared rays by ocher and adsorption of harmful substances by charcoal. Manufacturing to eliminate transportation costs and environmental pollution associated with the disposal of waste fibers. It relates to a flame-retardant interior construction and method of manufacturing the same.

일반적으로, 건축 내장재는 가연성 플라스틱이나 목재 등으로 이루어져 있어서 화재시에 각종 유독가스를 발생시키는 동시에 화재를 확산시켜 많은 인명과 재산피해를 발생시켰고, 또한 건축 내장재를 새로운 자원으로 사용하게 됨에 따라 실내 인테리어 비용이 상승하는 요인으로 작용하였다. In general, building interior materials are made of combustible plastics or wood, which generates various toxic gases during fire and at the same time, spreads the fire, causing a lot of human life and property damage, and using interior materials as a new resource. The cost increased.

그리고 낮은 가격으로 판매되는 일반 건축 내장재의 경우 포르말린(formalin), 톨루엔(toluene), 휘발성유기물질(volatile organic compound) 등을 포함하고 있어서 인체에 유해한 화학물질을 다량으로 발산시키는데, 이로 인해 건물 입주자의 경우 소위 새집 증후군(비염, 아토피성 피부염, 두드러기, 천식, 두통, 기관지염 등)을 보통 격게 된다. In addition, general building interior materials sold at low prices include formalin, toluene, and volatile organic compounds, which emit a large amount of chemicals harmful to the human body. In some cases, so-called sick house syndrome (rhinitis, atopic dermatitis, hives, asthma, headaches, bronchitis, etc.) is usually encountered.

따라서 최근에는 화재시 많은 인명과 재산피해가 발생되는 것을 방지하면서 새집 증후군 발생요인을 근본적으로 차단시킬 수 있게 한 기능성 보오드를 개발하고 있는데, 특히 보오드에 난연성 기능을 기본적으로 갖게 하면서 방수기능, 항균기능, 단열기능, 흡음기능 등이 모두 포함 되도록 하고 있다. Therefore, in recent years, functional boards have been developed to prevent the occurrence of many lives and property damages in the fire and to fundamentally block the factors causing sick house syndrome. Especially, the boards have a flame retardant function and have waterproof and antibacterial functions. , Heat insulation, sound absorption, etc. are included.

한편 종래의 기술을 실용신안등록번호 제20-253182호(내열성 고강도 재생 섬유합판과 그 제조법)에서 살펴 보면 다음과 같다. On the other hand, look at the conventional technology in Utility Model Registration No. 20-253182 (heat resistant high strength recycled fiber plywood and its manufacturing method) are as follows.

먼저 내열성 고강도 재생 섬유합판은, 합판을 구성하는 폐섬유의 조성이 셀룰로오스, 단백질, 폴리아크릴, 폴리아미드, 폴리프로필렌, 폴리에스터, 폴리비닐알콜 중 한 가지 또는 두 가지 이상을 임의로 선택하여서 된 폐섬유로 시트를 제조한 후, 상기 시트에 내포된 수분을 효과적으로 제거하기 위해 고주파를 이용하여 200℃ 에서 500℃의 온도로 1차 열처리 하고, 이후로 폐섬유를 구성하는 열가소성 섬유가 충분히 융해될 수 있도록 원적외선 가열기를 이용하여 280℃ 에서 380℃의 온도로 2분에서 20분 동안 가열하며, 이후로 상기 폐섬유의 부분적인 열분해와 내열성을 부여할 수 있도록 300℃에서 400℃의 온도로 가열하는 동시에 폐섬유가 치밀한 구조를 가지기에 충분하도록 10Kg/cm2에서 30Kg/cm2 사이의 압력으로 2분 에서 20분 동안 압착하여 제조한다. First, the heat-resistant high-strength recycled fiber plywood is a waste fiber in which the composition of the waste fibers constituting the plywood is arbitrarily selected from one or two or more of cellulose, protein, polyacryl, polyamide, polypropylene, polyester, and polyvinyl alcohol. After the furnace sheet is manufactured, the first heat treatment is performed at a temperature of 200 ° C. to 500 ° C. using high frequency to effectively remove the moisture contained in the sheet, and thereafter, the thermoplastic fibers constituting the waste fiber can be sufficiently melted. Heat from 2 to 20 minutes at a temperature of 280 ° C to 380 ° C using a far-infrared heater, and then heat it to a temperature of 300 ° C to 400 ° C to impart partial thermal decomposition and heat resistance of the waste fibers. It is produced by pressing the fibers for 2 to 20 minutes at a pressure between 10 Kg / cm 2 and 30 Kg / cm 2 so that the fibers have a dense structure.

상기한 종래의 기술은 단순히 폐섬유를 가열하면서 압착하여 하나의 재생 섬유합판을 제조하게 되는데, 이러한 재생 섬유합판은 난연액에 함침하는 공정이 생략되어 있기 때문에 화재시 유독가스를 발생시켜 인명피해를 증가시키면서 화재를 확산시키는 문제점이 있다. The prior art described above simply manufactures a single recycled fiber plywood by heating and compressing the waste fiber. Since the process of impregnating the flame retardant solution is omitted, it causes toxic gas in the event of fire, thereby preventing human injury. There is a problem of spreading the fire while increasing.

다른 문제점으로는 재생 섬유합판에 별다른 기능이 부가되지 않은 폴리계열 섬유로 되어 있기 때문에, 재생 섬유합판이 건축물 실내에 설치될 때 새집 증후군을 일으키는 요인으로 작용하게 되고, 또한 방수 및 항균성에 대해 취약한 결점을 지닌다. Another problem is that the regenerated fiber plywood is made of poly-based fibers with no added function, which causes the sickhouse syndrome when the regenerated fiber plywood is installed inside the building, and is also vulnerable to waterproofing and antibacterial properties. Has

또 다른 문제점으로는 폐섬유를 수거하는 데에 있어서 최근에는 한계점에 도달한 관계로, 재료 공급의 어려움으로 제품생산에 곤란함이 따르고 있다. Another problem is that the collection of waste fibers has recently reached a limit point, which is difficult to produce products due to the difficulty of supplying materials.

본 발명은 상기의 문제점을 해소하기 위해 안출한 것으로, 그 목적은 건축 내장재를 난연액에 함침하여 만듦으로서 화재의 확산 방지와 함께 유독가스에 의한 인명피해를 방지하는 데에 있다. The present invention has been made to solve the above problems, the object of the present invention is to impregnate the building interior materials in the flame retardant liquid to prevent the spread of fire and to prevent the damage of life by toxic gas.

다른 목적으로는 폐섬유를 활용하여 건축내장재를 제조하므로서, 폐섬유를 처리하는 데에 따른 운반비용과 환경오염 문제를 일소시켜 활용성이 향상되게 하는 데에 있다. Another purpose is to manufacture building interior materials using waste fibers, thereby eliminating the transportation costs and environmental pollution problems associated with treating waste fibers to improve their utility.

또 다른 목적으로는 보오드 일면에 황토층과 숯층 그리고 황토와 숯이 혼합된 시트층 중 어느 하나를 형성하므로서, 황토에 의한 원적외선 발생과 숯에 의한 유해물질 흡착으로 새집 증후군이 예방될 수 있게 하는 데에 있다. Another object is to form one of the ocher layer and charcoal layer and the ocher and charcoal sheet layer on one side of the board, so that sick house syndrome can be prevented by the generation of far-infrared rays by ocher and adsorption of harmful substances by charcoal. have.

또 다른 목적으로는 보오드에 흡음기능과 단열기능, 방수기능, 항균기능 등이 포함되도록 하므로서 우수한 건축내장재로 사용될 수 있게 하는 데에 있다. Another purpose is to be able to be used as an excellent building interior material by including a sound absorbing function, heat insulation function, waterproof function, antibacterial function to the board.
