본 발명은 불연성 보드 및 그 제조방법에 관한 것으로, 좀 더 상세하게는 화재에 대한 내화성을 개선되었을 뿐만 아니라 전체적으로 휨성과 굽힘강도, 내충격성이 보강되고 방수성을 보완하였으며, 보드의 표면에 다공질을 최소화하여 외관이 미려한 불연성 보드 및 그 제조방법에 관한 것이다.The present invention relates to a non-combustible board and a method of manufacturing the same, and more particularly, to improve the fire resistance to fire as well as to improve the bending and bending strength, impact resistance and waterproofing as a whole, and to minimize the porous on the surface of the board The present invention relates to a non-combustible board having a beautiful appearance and a manufacturing method thereof.
일반적으로 실내장식용 마감재를 비롯하여 칸막이, 천정, 저온창고, 지하실, 컨테이너의 벽면처리용 등의 건축물의 주요 구조부에는 목재나 파티클 보드(particle board)와 같은 셀룰로스 재료가 널리 사용되고 있으며, 특히 셀룰로스 보드는 중량비에 비해 상대적으로 높은 강도와 저렴한 비용 및 강성도(stiffness)면에서 효과가 뛰어나기 때문에 더욱 각광을 받고 있다. In general, cellulose materials such as wood and particle board are widely used in the main structural parts of buildings such as partitions, ceilings, low-temperature warehouses, basements, and wall treatments of containers, including interior finishing materials. Compared to the relatively high strength, low cost, and stiffness (stiffness) is excellent in effect because of its high attention.
최근 이와 같은 보드는 마감재로서 다양한 특성을 요구받고 있으며, 그 중에서도 셀룰로스 재료의 내화성을 개선하기 위한 시도가 이루어지고 있다. Recently, such a board has been required for various properties as a finishing material, and among others, attempts have been made to improve the fire resistance of cellulose materials.
이를 위하여, 목재 입자와 석고를 혼합·반죽하여 보드를 제조하거나 석면이나 돌가루, 석고 등을 접착제나 물 등과 혼합하여 유리섬유에 도포하여 불연성 보드를 만드는 방법들이 개시되고 있으나, 상기한 석고보드는 대체로 휨성이 약하고, 특히 석고가 경화시 석고의 입자가 유리섬유의 미세한 구멍사이로 침투가 어렵기 때문에 석고 및 돌가루와 유리섬유 간의 접착강도가 떨어지게 된다는 문제점이 발생하였다. To this end, a method of manufacturing a board by mixing and kneading wood particles and gypsum or mixing asbestos, stone powder, gypsum, and the like with an adhesive or water is applied to glass fibers to produce a non-combustible board. Generally, the warpage is weak, and in particular, when the gypsum is hardened, the gypsum particles are difficult to penetrate through the fine pores of the glass fiber, thereby reducing the adhesive strength between the gypsum and the stone and the glass fiber.
상기와 같은 문제점을 해결하기 위하여, 본 발명자가 선출원하여 등록된 특허 출원번호 제2002-68740호에서는 염화칼슘(CaCl2)과 황산(H2SO4)을 포함하는 용액에 각종 충진물을 혼합하여 페이스트를 만든 다음, 상기 페이스트를 부직포가 적층된 유리섬유에 도포하고 압축·성형하여 제조된 판상체를 마감재를 비롯한 건축주요부에 사용할 수 있는 불연성 보드 및 그 제조방법을 제공한 바 있으며, 이와 같은 불연성 보드는 유리섬유 내에 침투된 염화칼슘과 황산이 반응하여 석고를 생성함과 동시에 충진물로 사용된 규석 또는 진주석 및 활석과 부가적인 반응을 통하여 불연성을 갖는 층을 형성하게 된다. In order to solve the above problems, the present inventors have applied for a patent application No. 2002-68740 registered and registered in advance, the paste by mixing various fillers in a solution containing calcium chloride (CaCl 2 ) and sulfuric acid (H 2 SO 4 ) After making the paste, the paste is applied to glass fibers laminated with a non-woven fabric, and a non-flammable board and a method for manufacturing the plate-shaped body which can be used in a major part of a building including a finishing material have been provided. Calcium chloride and sulfuric acid penetrated into the glass fibers react to form gypsum and form a non-combustible layer through additional reaction with silica or pearlite and talc used as a filler.
상기와 같이 제조된 불연성 보드는 화재에 대한 내화성이 좋을 뿐만 아니라 보드로 부터 유해가스나 냄새가 배출되지 않아 인체에 안전하며, 충진물과 유리섬유의 접착강도가 좋아 전체적인 내구성을 향상시킬 수 있는 효과가 있었다. Non-flammable board manufactured as described above is not only good fire resistance to fire, but also harmful gas or odor from the board is safe for the human body, and the adhesive strength of the filler and glass fiber is good to improve the overall durability. there was.
그러나, 이와 같은 불연성 보드는 유리섬유와 페이스트 사이에 부직포층을 형성하여 휨현상에 대한 보완점을 제시하기는 하였으나, 전체적으로 유연성이 부족하여 휨성과 굽힘강도가 약하다는 문제점을 나타내고 있으며, 석고의 생성과정에서 각종 충진물의 반응하여 발생된 기포로 인해 제조된 보드의 표면이 다공질이 되어 외관이 미려하지 못하고, 내충격성도 떨어지는 또 다른 문제점이 있었다.However, such a non-combustible board, although a nonwoven fabric layer was formed between glass fibers and pastes, suggested a complementary point to the warpage phenomenon. However, the non-combustible board exhibited a problem in that the warpage and bending strength were weak due to lack of flexibility. Due to the bubbles generated by the reaction of the various fillings, the surface of the manufactured board becomes porous and the appearance is not beautiful, and there is another problem that the impact resistance is also poor.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여, 화재에 대한 내화성을 개선시킨 불연성 보드에 대하여 전체적으로 휨성과 굽힘강도가 보강되고 내충격성이 개선되었으며, 보드의 표면에 다공질을 최소화하여 외관이 미려한 불연성 보드 및 그 제조방법을 제공하는 것을 목적으로 한다.Therefore, in order to solve the above problems, the non-combustible board that has improved fire resistance to fire has been improved in overall bending and bending strength and improved impact resistance, and minimized the surface of the board to minimize the appearance of the non-combustible An object of the present invention is to provide a board and a method of manufacturing the same.

이하에서는 본 발명에 대하여 좀 더 상세하게 설명하도록 한다. Hereinafter, the present invention will be described in more detail.
먼저, 물에 염화칼슘을 첨가하고, 추가로 소정량의 황산을 투입하여 혼합한 혼합용액을 제조한다. 이 때 접착성을 부여하기 위하여 무기 접착제를 소량 첨가가능하며 그 양은 사용용도에 따라 달라지므로 크게 한정하지는 않는다.First, calcium chloride is added to water, and a predetermined amount of sulfuric acid is further added to prepare a mixed solution. In this case, a small amount of inorganic adhesive may be added to impart adhesion, and the amount thereof is not limited so much as it depends on the intended use.
상기 물에 대한 염화칼슘의 첨가량은 각 계절마다 또는 주위의 온도나 습도와 같은 외부환경에 의해 약간의 차이를 보일 수 있으며, 따라서 염화칼슘을 물에 대하여 보메도가 20 ~ 30°Be가 되도록 첨가하는 것이 바람직하다.The amount of calcium chloride added to the water may vary slightly depending on the season or the external environment such as ambient temperature or humidity. Therefore, the addition of calcium chloride to the water so that the degree of borrome is 20 to 30 ° Be desirable.
이와 같이 제조된 혼합용액은 염화칼슘과 황산이 반응하여 하기 화학식 1과 같이 석고를 생성하게 되는데, 다만 반응을 촉진하기 위한 별도의 촉매제가 첨가되지 않으므로 후공정을 시행할 수 있는 충분한 시간을 갖고 반응이 느리게 진행된다.The mixed solution thus prepared reacts with calcium chloride and sulfuric acid to produce gypsum as shown in the following Chemical Formula 1. However, since a separate catalyst for promoting the reaction is not added, the reaction is sufficient to carry out the post-process. It is going slow.
상기 혼합용액에 있어서 황산용액은 전체 혼합용액 100중량%에 대하여 0.02 ~ 0.05중량%가 되도록 혼합하게 되는데, 만약 황산을 0.02중량% 미만으로 첨가하게 되면 석고가 충분히 생성되지 못하여 충진물과 유리섬유 사이의 접착강도가 떨어지게 된다. 또한, 황산을 0.05중량%를 초과하여 첨가하여도 특별한 효과를 보이지 않으므로 제조비용의 증가를 줄이기 위하여 상기 범위로 한정되는 것이 좋다. In the mixed solution, the sulfuric acid solution is mixed so as to be 0.02 to 0.05% by weight relative to 100% by weight of the total mixed solution. If sulfuric acid is added less than 0.02% by weight, the gypsum may not be sufficiently formed, and thus, between the filler and the glass fiber. Adhesion strength drops. In addition, even when sulfuric acid is added in excess of 0.05% by weight does not show a particular effect is preferably limited to the above range in order to reduce the increase in manufacturing cost.
다음 공정으로는 상기에서와 같이 염화칼슘과 황산의 혼합용액에 규석 또는 진주석, 활석이 하나 이상 함유된 충진물을 20 ~ 80중량%를 투입하고 교반하여 페이스트상을 제조한다.In the next step, as described above, 20 to 80% by weight of a filler containing at least one of silica, pearlite, and talc is added to the mixed solution of calcium chloride and sulfuric acid to prepare a paste.
상기에서 사용되는 충진물은 제조되는 보드의 사용용도에 따라 규석 또는 진주석, 활석 중에 하나 또는 둘 이상을 선택하여 임의적인 배합비율에 의해 혼합하여 사용한다. 예를 들어 제조되는 보드의 비중을 높이기 위해서는 규석 대신에 발포된 진주석을 주로 사용하며, 보드의 광택을 향상시키기 위해서는 활석의 첨가량을 더 높인다.The filler used in the above is selected by using one or two or more of silica or pearlite, talc according to the use of the board to be manufactured by mixing by an optional blending ratio. For example, in order to increase the specific gravity of the manufactured board, foamed pearlite is mainly used instead of silica, and in order to improve the gloss of the board, the amount of talc is increased.
상기 충진물의 첨가량을 한정하는 것은, 혼합용액에 대하여 20중량% 미만으로 첨가되면 유리섬유 내로 혼입되는 충진물이 너무 적어 보드의 강도가 현저하게 떨어지게 되며, 80중량%를 초과하여 첨가하면 페이스트상의 점도가 너무 높아 유리섬유 내부로 침투되지 못하고 그 표면을 따라 흘러내리게 되는 문제점이 있기 때문이다.Limiting the amount of the filler to be added is that less than 20% by weight of the mixed solution is added to the glass fiber is too small filler to be significantly reduced the strength of the board, when the content of more than 80% by weight paste paste viscosity This is because it is too high to penetrate into the glass fiber and flow down along the surface thereof.
아울러, 상기한 혼합용액에는 무기질계 또는 유기질계, 혼합물계 방수액이나 방수가루가 추가로 첨가될 수 있으며, 이와 같은 방수액과 방수가루는 제조하고자 하는 보드의 크기나 두께에 따라 소정량 첨가되어 제조된 보드의 방수 및 습윤효과를 향상시키게 된다. 그 첨가량은 혼합용액에 대하여 20 ~ 30중량%가 추가로 첨가되는 것이 용액의 점도와 작업성 면에서 바람직하게 사용된다.In addition, the mixed solution may be additionally added to the inorganic or organic, mixture-based waterproofing or waterproofing powder, such waterproofing and waterproofing powder is prepared by adding a predetermined amount according to the size or thickness of the board to be prepared It will improve the waterproofing and wetting effect of the board. The addition amount is preferably 20 to 30% by weight based on the viscosity and workability of the solution further added to the mixed solution.
다음 공정으로는 상기와 같이 각종 충진물이 투입된 혼합용액에 유리섬유를 함침시키게 되는데, 다만 혼합용액의 염화칼슘과 황산이 반응하여 석고가 형성되기 전인 빠른 시간 내에 행하는 것이 바람직하다.In the next step, the glass fiber is impregnated into the mixed solution in which the various fillers are added as described above. However, it is preferable to perform the mixture within a short time before the gypsum is formed by the reaction of calcium chloride and sulfuric acid in the mixed solution.
이와 같이 함침시킨 유리섬유를 꺼내어 준비되어 있던 금형판 내에 놓고, 그 상면에 톱밥 또는 벼껍질을 포함하는 충진물이 투입된 염화칼슘과 황산의 혼합용액을 골고루 도포한다.The glass fiber impregnated in this way is taken out and placed in the prepared mold plate, and the mixed solution of calcium chloride and sulfuric acid, into which the filler containing sawdust or rice husk is put, is evenly applied.
상기한 혼합용액은 전술한 염화칼슘과 황산의 혼합용액과 동일하나, 이러한 혼합용액에 투입된 충진물은 규석 또는 진주석, 활석 뿐만 아니라 필수적으로 톱밥 또는 벼껍질을 포함하고 있다. 상기 톱밥 또는 벼껍질은 제조되는 보드의 경량화를 위하여 사용되는 것으로, 보드의 사용용도나 목적에 따라 사용자가 그 배합비를 임의적으로 조절하여 사용할 수 있으나, 통상적으로 충진물 100중량%에 대하여 20 ~ 80중량%가 포함시키는 것이 보드의 무게 대비 강도 측면에서 효과적이다. The mixed solution is the same as the above-described mixed solution of calcium chloride and sulfuric acid, but the filler added to the mixed solution includes not only silica or pearlite, talc, but also essentially sawdust or rice husk. The sawdust or rice husk is used to reduce the weight of the manufactured board, the user can arbitrarily adjust the compounding ratio according to the use or purpose of the board, but usually 20 to 80% by weight based on 100% by weight of the filler Inclusion of% is effective in terms of strength versus weight of the board.
또한, 상기와 같은 충진물에 산화마그네슘(MgO)이 포함되면 더욱 바람직하며, 이와 같은 산화마그네슘은 보드의 전체적인 유연성을 향상시켜 휨성과 굽힘강도를 향상시킴을 실시예를 통하여 실험적으로 확인할 수 있었다. 상기한 산화마그 네슘은 충진물 100중량%에 대하여 20 ~ 80중량%를 포함시킬 수 있다.In addition, it is more preferable to include magnesium oxide (MgO) in the filler as described above, such magnesium oxide was confirmed experimentally by the embodiment to improve the overall flexibility of the board to improve the bending and bending strength. The magnesium oxide may include 20 to 80% by weight relative to 100% by weight of the filler.
그 다음 공정으로 상기와 같이 혼합용액이 도포된 유리섬유에 또 다른 유리섬유를 적층시킨 다음, 롤러나 가압 프레스를 이용하여 제조되는 보드의 사용목적에 따라 소정의 두께와 크기를 갖는 판상체로 압축·성형하게 된다. 이 때, 상기한 압축·성형과정에서 유리섬유에 혼입된 충진물이 잘 분산될 수 있도록 금형에 진동을 가하여 주는 것이 바람직하다. Then, another glass fiber is laminated on the glass fiber coated with the mixed solution as described above, and then compressed into a plate having a predetermined thickness and size according to the purpose of the board manufactured by using a roller or a press. · Molded. At this time, it is preferable to apply a vibration to the mold so that the filler mixed in the glass fiber in the compression and molding process can be dispersed well.
이와 같이 압축. 성형된 판상체를 건조실에서 10 ~ 24시간 동안 완전건조시키고 양생하는 단계를 거쳐 소정의 규격으로 절단하여 제품화하게 된다.Compressed in this way. Through the step of completely drying and curing the molded plate-shaped body in a drying room for 10 to 24 hours, it is cut to a predetermined standard and commercialized.
상기한 양생단계는 판상체 내의 석고반응이 충분히 이루어질 수 있도록 함과 동시에 염분을 제거하고자 하는 것으로, 시멘트 및 콘크리트 분야에서 주로 사용되고 있는 수중양생, 기건양생, 전기양생, 피막양생 등을 통하여 이루어진다.The curing step is to remove the salt at the same time to allow the gypsum reaction in the plate enough to be made, it is made through underwater curing, air curing, electrical curing, film curing, etc. which are mainly used in the field of cement and concrete.
상술한 공정을 거쳐 제조된 보드는 일차적으로 유리섬유 내에 함침된 염화칼슘(CaCl2)과 황산(H2SO4) 용액이 서로 반응하여 석고(CaSO4·2H2O)를 생성하고, 추후 유리섬유 내부로 혼입된 충진물 중에서 규석 또는 진주석 및 활석과 부가적인 반응을 통하여 불연성을 갖는 층을 형성하게 된다. The board manufactured through the above-described process is primarily a solution of calcium chloride (CaCl 2 ) and sulfuric acid (H 2 SO 4 ) impregnated in the glass fiber to react with each other to produce gypsum (CaSO 4 · 2H 2 O), and later glass fiber The additionally mixed with the silica or pearlite and talc in the interior of the filling to form a non-combustible layer.
상기와 같이 유리섬유 내에서 처음 생성되는 석고 입자는 그 크기가 매우 작기 때문에 유리섬유사 사이에 형성된 공간 내에 균일하게 분포되어 있다가, 일정 시간이 경과한 뒤 혼입된 충진물들과 반응하여 강한 결합력을 갖은 상태에서 건조공정에서 계속적인 입자의 성장이 이루어지게 되며, 이로 인하여 유리섬유 및 충진 물 간의 접착강도를 효과적으로 증대시킬 수 있다.As described above, since the gypsum particles first generated in the glass fiber are very small, they are uniformly distributed in the space formed between the glass fiber yarns, and then react with the fillers mixed after a certain time to provide a strong bonding force. In this state, the continuous growth of the particles is made in the drying process, thereby effectively increasing the adhesive strength between the glass fiber and the filler.
또한, 종래 본 발명자가 선출원한 특허 출원번호 제2002-68740호의 제조방법과 달리, 본 발명에서는 염화칼슘과 황산의 혼합용액을 두 단계로 나누어 유리섬유에 함침 또는 도포함으로써, 석고의 성장이 어느 정도 이루어진 상태에서 충진물과 반응이 일어나도록 하여 기포의 발생을 최소화할 수 있으며, 따라서 제조된 보드가 다공질화 되는 것을 방지하여 외관이 미려해지며, 내충격성을 향상시킬 수 있다. In addition, unlike the manufacturing method of the patent application No. 2002-68740 previously filed by the present inventors, in the present invention by dividing the mixed solution of calcium chloride and sulfuric acid in two stages impregnated or applied to the glass fiber, the growth of gypsum is made to some extent It is possible to minimize the occurrence of bubbles by reacting with the filler in the state, thus preventing the porous board is manufactured, the appearance is beautiful, and the impact resistance can be improved.
상기 공정에 있어서, 유리섬유에 충진물이 투입된 혼합용액을 붓기 전과, 또 다른 유리섬유를 적층시키기 전에 각각 부직포를 적층시킴으로써, 상단 및 하단의 유리섬유와 충진물 사이에 각각 부직포층을 형성되도록 하면 좀 더 효과적이다.In the above process, the nonwoven fabric is laminated between the top and bottom glass fibers and the filling material by stacking the nonwoven fabrics before pouring the mixed solution in which the filler is added to the glass fibers and laminating another glass fiber, respectively. effective.
이는 상기와 같이 형성된 부직포층은 제조되는 불연성 보드의 휨현상을 줄일 수 있을 뿐만 아니라 유리섬유로 침투되는 충진물의 입자를 걸러줌으로써 작은 입자의 충진물이 유리섬유 내에 골고루 침투되도록 하는 역할을 하기 때문이다. This is because the nonwoven layer formed as described above not only reduces the warpage phenomenon of the non-combustible board manufactured, but also filters the particles of the fillers penetrating into the glass fibers so that the small particles of the fillers may be evenly penetrated into the glass fibers.
따라서, 본 발명의 제조방법에 의해 제조된 불연성 보드는 종래 본 발명자가 선출원한 불연성 보드의 효과인 화재에 대한 내화성이 좋고, 보드로 부터 유해가스나 냄새가 배출되지 않아 인체에 안전하며, 충진물과 유리섬유의 접착강도가 좋아 전체적인 보드의 내구성이 향상시킬 수 있다는 특징 뿐만 아니라 전체적으로 휨성과 굽힘강도, 내충격성이 보강되고 방수성능이 개선되었으며, 보드의 표면에 다공질을 최소화하여 외관이 미려해지는 효과를 가져온다.Therefore, the non-combustible board manufactured by the manufacturing method of the present invention has a good fire resistance against fire, which is an effect of the non-combustible board, which has been previously filed by the present inventors, and does not emit harmful gases or odors from the board and is safe for human body. As well as the adhesive strength of glass fiber, the overall board durability can be improved, as well as the overall flexural and bending strength and impact resistance are reinforced, and the waterproofing performance is improved, and the appearance is enhanced by minimizing the porous on the surface of the board. Bring.
