In general, buildings are coated with flame retardants in consideration of natural disasters such as earthquakes, wind, snow, water, and lightning, or human damage. However, such flame retardant coating is not at all helpful to the fire safety of residential buildings, rather, once ignited with organic materials, a lot of harmful toxic gases are generated, causing a lot of damage to life.

먼저, 이 실시예에 사용되는 불연성 조성물에 대해 설명한다.First, the nonflammable composition used for this Example is demonstrated.

도 1은 이 발명에 사용되는 불연성 조성물의 제조방법의 흐름도이다. 먼저, 도 1 및 아래의 표 1에 나타낸 함량에 따라 암모늄 폴리포스테이트(Ammonium polyphosphate)를 계량하여 60℃로 하여 구아니딘설파메이트(Guanidinesulfamate)를 첨가하여 반응을 관찰한 후, 100℃로 열을 가한다. 그런 다음, 20℃로 냉각하여 암모늄 헥사메타포스테이트(Ammonium hexametaphoshate)를 첨가한 다음, 암모늄 폴리포스테이트(Ammonium polyphosphate)를 소량 첨가해서 용해한 후 고형분을 25~30으로 측정 하여 정제수(물) 농도를 10℃ 이하로 조절한다.1 is a flowchart of a method for producing a nonflammable composition used in the present invention.

이 실시예의 불연성 조성물은 종합인산 칼바메타50을 함축한 혼합수용액을 PH6~8의 중성으로 조절하여 수용성 복합재료 조성물을 얻을 수도 있다. 이때, 중요한 것은 종합인산 칼바메타50을 나노입자로 처리한 후 2,500℃의 고열처리로 혼합하여 불연성 물질을 얻어내는 것이 바람직하다. In the non-combustible composition of this embodiment, a water-soluble composite material composition may be obtained by adjusting the mixed aqueous solution containing the composite phosphoric acid calvameter 50 to neutrality of PH 6-8. At this time, it is preferable to treat the multi-phosphorus carba meta 50 with the nanoparticles, and then to mix with a high heat treatment at 2,500 ° C. to obtain a nonflammable material.

또한, 이 실시예의 불연성 조성물은 폴리인산염, 에스테르 화합물을 함축한 복합수용성으로 만들어 폴리에스테르를 가미한 고형분을 만들 수도 있다. In addition, the non-combustible composition of this Example can also be made into the water-soluble complex containing the polyphosphate and ester compound to create a solid content with polyester.

이 실시예의 불연성 조성물은 페놀수지와 비소, 붕소, VOC, 할로겐 등 인체에 유해한 물질을 전혀 사용하지 않고 제조하는 큰 특징을 갖는다.The non-combustible composition of this embodiment has a great feature of producing without using any phenolic resin, arsenic, boron, VOC, halogen, and other substances harmful to the human body.

또한, 이 실시예의 불연성 조성물은 상기 물질들을 여러 번 서로 다르게 혼합하고 온도변화와 고온의 열처리를 통해 불연성 물질을 얻을 수도 있다.In addition, the non-combustible composition of this embodiment may be obtained by mixing the materials differently several times and through the temperature change and high temperature heat treatment.

이 실시예의 불연성 조성물은 연소시에 산소를 차단하는 역할과, 연소시에 비산재가 나오지 않도록 하는 역할을 하며, 또한 탄화온도를 차단하여 유해물질을 감소시킬 뿐만 아니라 무색무취하며, 목재류를 이 실시예의 불연성 조성물에 함침하여 불연처리할 경우 반영구적인 사용이 가능하다.The non-combustible composition of this embodiment serves to block oxygen during combustion, to prevent fly ash from coming out during combustion, and also to block carbonization temperature, not only to reduce harmful substances, but also to be colorless and odorless. When impregnated with a nonflammable composition, semi-permanent use is possible.

이 실시예의 불연성 조성물은 목재류에 침투되었을 때에 목재의 뒤틀림이나 팽창 및 수축 등을 어느 정도 막을 수 있을 뿐만 아니라, 방부, 방충, 개미 피해도 줄일 수 있는 효과가 있다. The non-combustible composition of this embodiment can prevent warping, expansion and contraction of wood to some extent when penetrated into woods, as well as reducing the preservation, insect repellent, and ant damage.

이 실시예의 불연성 조성물을 목재류에 사용할 경우에는, 산소를 차단하고, 가연물을 없애며, 탄화온도를 차단하고, 유해물질을 감소시키며, 무색무취하며, 반영구적인 사용이 가능하다는 특징을 갖는다.When the non-combustible composition of this embodiment is used for timbers, it is characterized by blocking oxygen, removing combustibles, blocking carbonization temperature, reducing harmful substances, colorless and odorless, and semi-permanent use.

또한, 이 실시예의 불연성 조성물은 연소시에 다이옥신, 비산재 등이 검출되지 않으며, non할로겐의 난연물질을 개발한 것이 특징이라 할 수 있다. 즉, 현재까지는 유독성이 강한 할로겐이나 붕소, 비소 등을 사용한 난연재는 소개되고 있으나, 친환경 난연재를 개발한 것은 아직까지 전무한 상태로서, 따라서 이 실시예의 불연성 조성물은 큰 의미를 갖는다 할 수 있다.In addition, the non-combustible composition of this embodiment can be characterized in that dioxin, fly ash, etc. are not detected during combustion, and non-halogen flame-retardant materials have been developed. In other words, flame retardants using halogen, boron, arsenic, etc., which are highly toxic, have been introduced so far, but eco-friendly flame retardants have not been developed yet, and thus the non-flammable composition of this embodiment can have great significance.

다음으로는, 상기와 같이 구성된 불연성 조성물을 이용하여 이 발명에 따른 불연 목자재의 제조방법을 설명한다.Next, the manufacturing method of the nonflammable wood material which concerns on this invention using the nonflammable composition comprised as mentioned above is demonstrated.

도 2는 이 발명의 한 실시예에 따른 불연 목자재의 제조방법의 흐름도이다. 도 2에 도시된 바와 같이, 적용할 목자재를 함유율 10% 이하가 되도록 완전히 사전 건조한다. 그런 다음, 건조된 목자재를 20KG압의 함침탱크를 갖는 불연처리 기계에 적재한다. 그리고, 함침탱크 내의 목자재를 40℃에서 30분 정도 스팀을 가해 가열하는 열처리과정을 수행한다. 즉, 스팀을 가함으로써 목자재가 수분을 흡수하고, 그에 따른 섬유질이 팽창되도록 한다.2 is a flowchart of a method of manufacturing a non-combustible wood material according to an embodiment of the present invention. As shown in Fig. 2, the wood material to be applied is completely pre-dried to have a content of 10% or less. The dried wood is then loaded into a non-flammable machine with a 20KG pressure impregnation tank. Then, the wood material in the impregnation tank is heated by applying steam at 40 ° C. for about 30 minutes. In other words, by applying steam, the wood material absorbs the moisture, thereby causing the fiber to expand.

이 상태에서 목자재 내부와 함침탱크 내에 있는 공기를 완전 진공시킨다. 이때, 진공처리는 740미리기압에서 30분간 행한다. 그 후에 상기와 동일한 열처리 및 진공과정을 한 번 더 수행한다. 이러한 열처리 및 진공과정을 통해 목자재 내에 불연성 조성물이 원활하게 침투되도록 함으로써, 불연처리가 우수한 목자재를 생산하기 위해서다.In this state, the air inside the wood material and in the impregnation tank is completely vacuumed. At this time, a vacuum process is performed for 30 minutes at 740 atmospheric pressure. Thereafter, the same heat treatment and vacuum process as above are performed once more. Through the heat treatment and vacuum process to allow the non-combustible composition penetrates smoothly into the wood material, to produce a wood material excellent in non-combustible treatment.

그런 다음, 상기와 같이 구성된 불연성 조성물(불연처리약제)을 함침탱크 내에 투입한다. 이러한 불연처리약제를 투입한 후 압력 8~20kg/cm2(목자재의 종류에 따라 압력조절)의 압력으로 목자재의 내부 심재에 불연처리약제를 투입한다. 이러한 가압공정은 목자재의 종류에 따라 30분에서 24시간까지 수행한다. 예를 들어, 목자재가 루바인 경우 대략 3시간, 합판인 경우 대략 1시간, MDF인 경우 대략 30분, 원목(목재)인 경우 대략 5시간, 투수목재인 경우 24시간의 가압공정을 행한다. Then, a nonflammable composition (nonflammable chemical) configured as described above is introduced into the impregnation tank. After injecting these non-combustible chemicals, the non-combustible chemicals are injected into the inner core of the wood at the pressure of 8 ~ 20kg / cm 2 (adjusting the pressure according to the type of wood). This pressurization process is carried out from 30 minutes to 24 hours depending on the type of wood material. For example, the pressurization process is performed for approximately 3 hours for wood, approximately 1 hour for plywood, approximately 30 minutes for MDF, approximately 5 hours for solid wood (wood), and 24 hours for permeable wood.

그런 다음, 가압을 풀고 불연처리약제를 함침탱크에서 배출시킨 후 탱크내부의 목자재의 표면을 깨끗이 세척한다. 그리고, 목자재의 종류에 따라 차등 건조시킨다. 즉, 자연건조 2일, 강제건조(40~80℃의 건조실) 3일, 자연건조 1일 등을 통해 수분 함수율 10~20%를 갖도록 건조시킨다. 그런 다음, 크기 및 용도별로 분류하고, 검수 및 포장한 후 출고한다. Then, the pressure is released and the non-flammable chemical is discharged from the impregnation tank, and then the surface of the wood material inside the tank is cleaned. And it is made to dry differentially according to the kind of wood material. That is, it is dried to have a water content of 10 to 20% through two days of natural drying, three days of forced drying (drying room of 40 ~ 80 ℃), one day of natural drying. They are then sorted by size and use, inspected, packed and shipped.

The gas hazard test was commissioned and confirmed by the relevant organizations, "Korea Institute of Construction Technology, Disaster Prevention Testing Institute, and Fire Protection Assistance Corporation," respectively. In other words, the pass test of the semi-combustible test passed the condition of "8M / J (200KW) using a calorimeter, and there should be no cracks or holes on the front and back." This condition was passed with a "mouse stop time of 9 minutes or more in space".
