Disclosed is a method of manufacturing a nonflammable interior panel using sawdust and wood chips, wherein a nonflammable interior panel uses a wood material as a main material while having high strength, and excellent warmth-keeping, insulation and noise absorption, and has a function as a fire-retardant construction material by inducing the mineralization and flame-resistance of a wood component due to a chemical reaction between the wood material, cement and additives, and then, a coating material such as an existing crystal sealer is applied to the surface of the material to form the surface like lithia (lithium-aluminum minerals) glass such that a film which does not cause decomposition or dissolution even at a maximum temperature of 1,300℃ can be formed, and, as a result, the fire-retardant material combined with wood and cement causes a material property change to a nonflammable material to have excellent heat resistance without producing toxic gas in case of a fire. According to the present invention, the method comprises the following steps of: preparing an additive by diluting an aluminum sulfate solution in water; preparing a wood material by mixing sawdust with wood chips; putting the wood material into the additive and settling the same for 10 minutes at a temperature of 65-80℃; and mixing cement through a stirrer in a state, in which the moisture content of the wood material is 75-80%, to form a panel through a vibration and compression technique.
목재소재를 주원료로 하면서도 강도가 크며, 보온, 단열, 소음흡수력이 우수하고, 목재소재, 시멘트 및 첨가제가 화학적 반응을 일으켜 목재성분의 광물화 및 화염저항성을 유도하여 난연건축재로서의 기능을 가지게 한 후, 기존에 개발되어있는 크리스탈 실러와 같은 도장재를 소재 표면에 도포함으로서 표면을 리티아(리듐알루미늄광물)그라스와 같이 조성되도록 하여 최고 1,300℃에서도 분해나 용해를 일으키지 않는 피막을 형성토록 함으로써 목재와 시멘트가 결합된 난연성소재를 불연성소재로 물성변화를 일으키도록 하여 화재발생시 유독가스를 내지 않으며 내열성이 뛰어난 톱밥과 목재칩을 이용한 불연내장 인테리어판넬의 제조방법을 개시한다. 본 발명은, 황산알루미늄 수용액을 물에 희석한 첨가제를 준비하는 단계; 톱밥과 목재칩을 혼합하여 구성된 목재소재를 준비하는 단계; 상기 목재소재를 첨가제에 넣고 65℃~80℃의 온도에서 10분간 침적시키는 단계; 및 상기 목재소재의 함수율이 75~80%인 상태에서 교반기에 의해 시멘트를 혼합하여 진동 및 압축방식에 의해 판넬을 성형하는 단계로 이루어진다.
