Abstract

PURPOSE: A flame retarding, antiseptic, high-density timber manufacturing method for an environmentally friendly wood board and flooring board is provided to impregnate a denaturalized sodium aqueous solution into timber and to inject carbon dioxide gas into the timber for hardening, thereby transforming loose wooden fibrous tissues into compact wooden fibrous tissues with reinforced durability. CONSTITUTION: A flame retarding, antiseptic, high-density timber manufacturing method for an environmentally friendly board and flooring board comprises the following steps: A timber dried to have 10% less moisture content by weight is processed into a wood board or a flooring board and then stored in a tank for impregnation. The tank for impregnation is vacuum-decompressed. The mole ratio of sodium is intensified to have a SiO2/Na2O mole ratio of 3 or more in a sodium silicate solution having the structure of Na2O nSiO2 xH2O in order to loosen cell walls and tracheids of the timber for an easy impregnation, and a first denaturalized sodium silicate solution combined with a metal ion such as Li or Ba is injected into the tank for impregnation. The tank for impregnation is pressurized to impregnate the first denaturalized sodium silicate solution into the wood board and the flooring board. The pressure in the tank for impregnation is released to return the first denaturalized sodium silicate solution back into the tank for impregnation, and the tank for impregnation is vacuum-decompressed again. The mole ratio of sodium is intensified to have a SiO2 / Na2O mole ratio of 3 or more in a sodium silicate solution having the structure of Na2O nSiO2 xH2O to maximize a frame retardant property, antisepsis, and sensitivity; and a second denaturalized sodium silicate solution combined with a metal ion such as Al, Li or Ba is injected into the tank for impregnation. The pressure in the tank for impregnation is released to return the second denaturalized sodium silicate solution back into the tank for impregnation, and then carbon dioxide is injected for the first and the second denaturalized sodium silicate solution inside the timber to be ion-bonded and hardened to be deposited to the cell walls of the timber. The wood board and the flooring board and carbon dioxide are removed, and the wood board and the flooring board are dried.

Description

목재판재 및 플로어링보드를 위한 난연 방부성 고밀도 목재 제조방법{The fireproof lumber manufacturing method for a lumber board and a flooring board}The fireproof lumber manufacturing method for a lumber board and a flooring board}

본 발명은 목재판재 및 플로어링보드를 위한 난연 방부성 고밀도 목재 제조방법에 관한 것으로서, 좀더 상세하게 설명하면 기존에 목재의 특성에 따라 다양한 용도로 한정하여 사용하던 것에서 상대적으로 강도가 낮은 목재를 이용하여 고밀도로 변화시켜 가볍고 튼튼하며 내구성이 뛰어나면서 불에 타지 않는 목재를 제공하기 위하여 개발된 목재판재 및 플로어링보드를 위한 난연 방부성 고밀도 목재 제조방법에 관한 것이다.
The present invention relates to a flame-retardant anti-corrosive high density wood manufacturing method for wood boards and flooring board, in more detail, the high-density using a wood with a relatively low strength from the conventional limited to various uses according to the characteristics of the wood The present invention relates to a flame retardant antiseptic high density wood manufacturing method for wood boards and flooring boards developed to provide light, strong, durable, and non-burning wood.

인류는 우리 주변에서 볼 수 있는 흙, 나무, 풀, 돌 등을 이용하여 집을 포함하여 다양한 물건을 만들어 왔으며 현대에 이르러서는 각종 금속뿐만 아니라 인공적인 합성물질을 이용하여 이러한 물건을 만들고 있어 천연재료를 이용하는 경우는 급속하게 줄어들고 있는 추세이다.Human beings have made a variety of things, including houses, using soil, trees, grass, and stones that can be seen around us.In modern times, humans make such materials using artificial synthetic materials as well as various metals. The use case is rapidly decreasing.

하지만 목재는 썩거나 내화성이 지극히 떨어지는 단점에도 불구하고 일상 생활에서 건축재료와 가구 등의 다양한 용도로 사용이 지속되고 있으며 목재의 성질을 개선하기 위한 노력도 계속되고 있다.However, despite the weakness of rotting or extremely low fire resistance, wood is being used for various purposes such as building materials and furniture in daily life, and efforts are being made to improve the properties of wood.

그 중 한가지는 WPC(wood-polymer-composite)로 목질 내부의 수분 이동통로에 고분자 수지를 주입시켜 목재의 변형을 최소화함은 물론, 목재의 내구성, 내마모성, 경도, 내수성 등을 강화시켜 주는 함침 공법으로 상당히 많은 부분에 도입되어 사용되고 있으나 고분자 수지는 일반적으로 폴리에스테르 수지나 비닐에스테르 수지가 사용되나 이러한 휘발성 유기 화합물(VOC)의 사용은 실내 및 실외의 공기 오염물질을 대표하는 것이라고 할 수 있으며 친환경적으로 부적합하다는 단점이 있다.One of them is WPC (wood-polymer-composite), which injects polymer resin into the moisture transport passage inside the wood to minimize the deformation of the wood, and to impregnate the wood's durability, abrasion resistance, hardness, and water resistance. Although the polymer resin is generally used in polyester resin or vinyl ester resin, the use of these volatile organic compounds (VOC) is representative of indoor and outdoor air pollutants. There is a disadvantage of being inadequate.

또 다른 방법으로는 목재를 미생물(박테리아,곰팡이)이나 곤충의 피해로부터 보호하기 위해 구리와 비소 및 크롬을 가압하여 주입하는 가압식 방부처리기술이 있으나, 이렇게 방부처리된 목재라도 방부약제의 내구성능에 한계가 있어 갈색부후균 중에는 구리를 함유하고 있는 방부제에 대해서 내성이 있는 목재 부후균이 존재하기 때문에 방부약제로 처리된 목재라 해서 썩지 않는 것은 아니며, 변색균은 방부제를 분해 또는 해독할 수 있는 능력이 있어 그 효용이 줄어들고 있고, 특히 CCA약제의 경우 독극물인 비소를 함유하고 있어 전 세계적으로 규제 대상이다.Another method is pressurized preservative technology that presses and injects copper, arsenic and chromium to protect wood from microorganisms (bacteria, mold) or insect damage. Because of the limitation that brown fungi are resistant to copper-containing preservatives, wood-treated fungi are not incorruptible because wood treated with preservatives does not decay. Because of this, its utility is diminishing. In particular, CCA pharmaceuticals contain arsenic, which is a poison, and are therefore regulated worldwide.

또, 목재의 방염/난연처리는 시멘트,석고,산화마그네슘 등을 혼합한 화합물로 목재의 표면을 피복하여 열의 확산과 산소와의 접촉을 막아 연소를 제어하는 기술과 발포성 도료를 코팅처리에 의해 가열되었을 때 발포층을 형성하여 차염효과와 산소 공급 차단 등의 작용으로 방화효과를 나타내는 기술이 있으며, 목재에 약제를 주입하여 약제가 열에 의해 분해되어 목재의 분해성분과 결합시켜 열적으로 안정한 성분이나 불휘발성의 성분이 되도록 하는 방법으로 할로겐원소가 대표적으로 사용되며 인산염, 황산암모늄, 붕소계, 염화아연 등도 사용된다.In addition, the flame retardant / flame retardant treatment of wood is a compound mixed with cement, gypsum, magnesium oxide, etc., which covers the surface of wood to prevent heat diffusion and contact with oxygen, and controls combustion and heats the effervescent paint by coating. When it forms, it forms a foam layer and shows the fire prevention effect by the effect of flame retardation and blocking oxygen supply.The chemical is injected into wood, and the chemical is decomposed by heat and combined with the decomposition component of wood to be thermally stable or fire. Halogen is typically used as a method of making volatile components, and phosphate, ammonium sulfate, boron-based, and zinc chloride are also used.

그러나 목재에 난연제를 피복하거나 코팅하는 기술은 피복 표면을 지속적으로 유지키 어렵고 강한 화염으로 인해 피복면이 파괴되면 난연효과를 상실하게 되는 단점이 있으며, 연쇄반응을 저지하기 위한 할로겐 화합물의 주입은 화합물 자체가 고가이므로 경제적 효용성이 떨어지고 인화시 유해물질 발생우려가 있다는 단점이 있다.
However, the technique of coating or coating a flame retardant on wood has a disadvantage in that it is difficult to continuously maintain the surface of the coating and loses the flame retardant effect when the coated surface is destroyed by a strong flame. Since it is expensive, it has a disadvantage in that economic efficiency is low and there is a concern that harmful substances may be generated when ignited.

도 1은 본 발명의 일 실시 예에 따른 플로우 차트1 is a flow chart according to an embodiment of the present invention.

이에 본 발명의 구성을 당업자가 용이하게 이해하고 재현할 수 있도록 상세하게 설명하면 다음과 같다.Thus, the configuration of the present invention will be described in detail so that those skilled in the art can easily understand and reproduce.

규산나트륨(규산소다)은 Na2O·nSiO2·xH2O의 화학식을 가지며 이때 n과 x는 상수로서 수용성 규산염 중 가장 널리 사용되고 있는 무기 화합물이라고 할 수 있다.Sodium silicate (sodium silicate) has a chemical formula of Na2O.nSiO2.xH2O, where n and x are constants and are the most widely used inorganic compounds among water-soluble silicates.

그 특징은 고결체의 초기강도 발현이 빠르고 상온에서 안정성과 작업성이 우수하지만 그 자체로는 목재에 함침이 되지않고 수용성으로 내수성에 취약하다는 단점이 있으나 본원에서는 이러한 문제점을 해결할 수 있는 변성 규산나트륨을 개발하여 이러한 변성 규산나트륨을 함침하여 목재의 성질을 강화할 수 있도록 하는 방법을 개발한 것이다.Its characteristics are that the initial strength of solidified fast and excellent stability and workability at room temperature, but it is not impregnated to wood itself, but water-soluble due to its weakness in water resistance, but modified sodium silicate that can solve this problem in the present application Was developed to impregnate such modified sodium silicate to enhance the properties of wood.

도 1은 본 발명의 일 실시 예에 따른 플로우 차트로서, 본원에 의한 과정은 함수율 10% 이하로 건조된 목재를 목재판재 및 플로어링 보드로 가공한 후 함침용 탱크안에 적재하는 과정과;1 is a flow chart according to an embodiment of the present invention, the process according to the present invention is a process for loading the dried wood with a water content of 10% or less after processing into a wood plate and flooring board impregnation tank;

함침용 탱크를 진공 감압하는 과정과;Vacuum depressurizing the impregnation tank;

Na2O·nSiO2·xH2O의 구조를 가지는 규산나트륨 수용액에서 SiO2/Na2O의 몰비가 3 이상을 가지도록 나트륨의 몰비를 강화하여 목재 세포벽과 가도관들을 함침에 용이하도록 이완시키도록 하고 리튬(Li)과 바륨(Ba) 등의 금속이온과 결합한 1차 변성 규산나트륨 수용액을 함침용 탱크안에 주입하는 과정과;In the sodium silicate solution having the structure of Na2O, nSiO2, xH2O, the molar ratio of sodium is increased so that the molar ratio of SiO2 / Na2O is 3 or more so that the wooden cell walls and the conduits can be easily relaxed to be impregnated, and lithium (Li) and barium ( Injecting a primary modified aqueous sodium silicate solution combined with metal ions such as Ba) into an impregnation tank;

함침용 탱크를 가압하여 1차 변성 규산나트륨 수용액을 목재판재 및 플로어링 보드에 함침시키는 과정과;Pressurizing the impregnation tank to impregnate the first modified aqueous sodium silicate solution on the wood board and the flooring board;

압력을 해제하고 1차 변성 규산나트륨 수용액을 탱크로 돌려보내며 다시 함침용 탱크를 진공 감압하는 과정과;Releasing the pressure, returning the first modified aqueous sodium silicate solution to the tank and vacuum depressurizing the impregnation tank again;

Na2O·nSiO2·xH2O의 구조를 가지는 규산나트륨 수용액에서 SiO2/Na2O의 몰비가 3 이하가 되도록 규산성분을 강화하여 난연, 방부, 감도를 극대화하도록 하고 알루미늄(Al)과 리튬(Li)과 바륨(Ba) 등의 금속이온과 결합한 2차 변성 규산나트륨 수용액을 함침용 탱크안에 주입하는 과정과;In the sodium silicate solution having the structure of Na2O · nSiO2 · xH2O, the silicic acid component is strengthened so that the molar ratio of SiO2 / Na2O is 3 or less to maximize flame retardancy, antiseptic and sensitivity, and aluminum (Al), lithium (Li) and barium (Ba Injecting a secondary modified sodium silicate aqueous solution combined with metal ions such as) into an impregnation tank;

압력을 해제하고 2차 변성 규산나트륨 수용액을 탱크로 돌려보내고 내부에 이산화탄소를 주입하여 1차 및 2차 변성 규산나트륨 수용액과 목재 내부에서 이온결합하여 경화되면서 세포벽에 증착되는 과정과;Releasing the pressure and returning the secondary modified sodium silicate aqueous solution to the tank and injecting carbon dioxide therein to deposit the first and second modified sodium silicate aqueous solutions and the ionic bond in the wood to be deposited on the cell wall;

이산화탄소를 제거하고 가공된 목재판재 및 플로어링 보드를 건조시키는 과정의 일련의 과정이 연속적으로 이루어짐을 특징으로 한다.It is characterized by a series of processes of removing carbon dioxide and drying the processed wood board and flooring board.

즉 1차적으로 1차 변성 규산나트륨을 함침시켜 목재세포벽과 가도관들을 이완시켜주고 2차적으로 2차 변성 규산나트륨을 함침시켜 규산성분에 의하여 난연, 방부, 강도를 높일 수 있도록 하며 최종적으로 이산화탄소를 결합시켜 수용액이 경화되어 내수성을 강화시키는 것이라고 할 수 있다.
In other words, the first impregnated sodium silicate is used to relax the wood cell walls and pipes, and the second impregnated sodium silicate is used to increase the flame retardancy, preservation, and strength by the silicic acid component. It can be said that the aqueous solution is cured to enhance the water resistance.

이때 진공 감압하는 두 번의 과정은 0.1MPa로 3시간 이상 진행하며, 1차 변성 규산나트륨 수용액을 함침시키는 가압과정은 1.3MPa 이상의 압력으로 2시간 진행하며, 2차 변성 규산나트륨 수용액을 함침시키는 가압과정은 1.3MPa 이상의 압력으로 4시간 진행하는 것을 본원의 추가적인 실시 예로 제시하였다.At this time, the two processes of vacuum decompression proceed at 0.1 MPa for 3 hours or more, and the pressurizing process of impregnating the first aqueous sodium silicate solution is carried out at a pressure of 1.3 MPa or more for 2 hours, and the pressurizing process of impregnating the secondary modified sodium silicate aqueous solution. 4 hours at a pressure of 1.3MPa or more is presented as an additional embodiment of the present application.

이때 목재의 종류 및 상태에 따라 압력과 시간은 다소 유동적이라고 할 수 있으나 본원의 목적과 효과에서 재시한 바와 같이 조직이 비교적 성긴 소프트우드 즉 파인, 삼나무 등의 나무를 단풍나무와 같은 하드우드와 같은 성질을 가지도록 고밀도 처리하기 위한 것으로 일반적인 소프트우드에서 가장 적합한 압력과 시간을 제시한 것이라고 할 수 있다.At this time, the pressure and time can be said to be somewhat fluid depending on the type and condition of the wood. It is for high density processing to have the property, and it can be said that it suggested the most suitable pressure and time in general softwood.

이러한 소프트우드와 하드우드는 그 가격에서 상당한 차이를 가지고 있으나 본원은 규산성분에 의하여 목재가 방염, 난연, 방부의 성질을 가지도록 하고 성긴 조직의 내부에 함침되어 강도를 높일 수 있어 경제적인 비용으로 각종 목재판재 및 바닥용 플로어링 보드로 활용할 수 있게 된다.These softwoods and hardwoods have a considerable difference in their price, but the present application allows the wood to have flame retardant, flame retardant, and antiseptic properties by silicic acid, and it can be impregnated inside the coarse tissue to increase its strength. It can be used as various wood boards and flooring boards.

또 본원에서의 나트륨과 구산 성분은 인체에 무해한 무기질로 기존의 구리화합물과는 달리 친환경적이며 내구성도 좋아 아토피를 포함하는 각종 질병에도 효과가 있다.In addition, the sodium and guic acid component in the present application is harmless to the human body, unlike the conventional copper compound is environmentally friendly and good durability, and is effective in various diseases including atopy.
