Semi-nonflammable sound absrobing panel and manufacturing method of the same
One embodiment of the present invention provides a method for manufacturing a semi-inflammable sound-absorbing panel, comprising the steps of: preparing a fiber mixture by mixing 40 to 80 wt% of natural fiber and 20 to 60 wt% of synthetic fiber; primarily molding the fiber mixture to obtain a molded article having a density of 180 to 350 kg/m^3; impregnating the molded article with a flame retardant liquid; drying the impregnated molded article; secondarily molding the dried molded article to form a semi-inflammable panel; and forming a plurality of sound-absorbing holes by semi-perforating one surface of the semi-inflammable panel, wherein each of the plurality of sound-absorbing holes has a depth of 30 to 90 % of the panel thickness, thereby providing a semi-inflammable sound-absorbing panel with improved sound-absorbing performance.
본 개시의 일구현예에 따르면 40 중량% 내지 80 중량%의 천연 섬유 및 20 중량% 내지 60 중량%의 합성 섬유를 혼합하여 섬유 혼합물을 준비하는 단계; 상기 섬유 혼합물을 1차 성형하여 180 kg/㎥ 내지 350 kg/㎥의 밀도를 갖는 성형품을 얻는 단계; 상기 성형품에 난연액을 함침시키는 단계; 상기 함침된 성형품을 건조시키는 단계; 상기 건조된 성형품을 2차 성형하여 준불연 패널을 형성시키는 단계; 및 상기 준불연 패널의 일면 상에 반타공하여 다수의 흡음홀을 형성시키는 단계를 포함하고, 여기서, 상기 다수의 흡음홀의 각각은 패널 두께의 30% 내지 90%의 깊이를 갖는 준불연 흡음 패널의 제조 방법을 제공하여, 흡음 성능이 개선된 준불연 흡음 패널을 제공할 수 있다.
