Description
본 발명은 섬유 판재(fiber board)에 관한 것으로서, 특히 단열, 흡음 및 결로방지효과가 우수하고 양면의 밀도차를 두어 시공이 편리하며 재활용이 가능한 건축내장재용 섬유 판재에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber board, and more particularly, to a fiber board for building interior materials having excellent insulation, sound absorption, and condensation preventing effects, and having a convenient density and recyclability due to a difference in density between two sides.
건축자재 및 산업용 자재 등에는 주로 암면, 석고판재, 유리섬유, 스티로폴 등 단열재와 압축목재와 접착제로 구성된 하드판재 등이 사용되고 있으나, 이러한 판재들은 인체에 유해한 물질을 배출하는 것으로 알려져 있으며 또한 재활용이 불가능하여 환경공해를 일으키는 등의 문제점이 있다.In building materials and industrial materials, rock wool, gypsum board, glass fiber, styropol, etc. are mainly used as insulation materials and hard boards composed of compressed wood and adhesives. However, these boards are known to emit substances harmful to the human body and cannot be recycled. There is a problem such as causing environmental pollution.
종래 섬유판재의 제조와 관련하여 다음과 같은 방법들이 특허문헌에 공지되어 있다. 한국공개 특허공보 공고 87-5764호에 의하면, 섬유상의 폴리프로필렌을 잘게 분쇄하고 이에 아크릴섬유, 폴리에스테르 섬유, 나일론 섬유 등의 화학섬유를 10mm 이상으로 절단하여 소면기에 넣어 만든 웹(web)을 가열실에서 일정시간 가열한 후 절단하여 압압판으로 압축성형한 화섬판재가 제시된다. 그러나 이 방법은 화섬물을 10mm 정도의 단섬유로 절단함으로써 단섬유들 간의 엉킴이 적어 잘 부서지는 단점이 있는 것이다. The following methods are known in the patent literature in connection with the production of conventional fiberboard materials. According to Korean Laid-Open Patent Publication No. 87-5764, a fibrous polypropylene is finely pulverized, and a web made by cutting a chemical fiber such as acrylic fiber, polyester fiber and nylon fiber to 10 mm or more and heating it into a carding machine is heated. It is presented a fiber board, which is formed by heating in a chamber for a certain time, cutting and compression molding into a press plate. However, this method has the disadvantage of breaking the sapphire into short fibers of about 10 mm, so that there is less tangle between the short fibers.
또한 한국 특허 공보 공고 95-6863호에 의하면 폐화섬물을 50∼100 mm 정도의 장섬유로 절단하여 타면기에서 타면하여 솜상태로 하고 이를 일정두께의 매트형태로 한 다음 이들을 적당한 두께의 층으로 적층하여 섬유실 끼리 서로 일체가 되도록 고열, 고압으로 가열가압함으로써 화섬판재를 제조하는 방법이 알려져 있다. 그러나 상기한 방법으로 제조한 화섬판재는 고온 및 고압에서 성형되므로 섬유구성물질인 고분자 물질의 분해를 초래하게 되고 섬유의 고유특성이 상실되는 문제점이 있는 것이다. 또한 상기한 종래의 방법들은 폐화섬물을 이용하기 때문에 작업환경이 불량하고 환경공해물질을 발생시키는 문제점을 안고 있는 것이기도 하다. In addition, according to Korean Patent Publication No. 95-6863, the waste islands are cut into 50 to 100 mm long fibers, which are then spun on the other side of the machine to form a cotton mat, and then they are laminated in a certain thickness. There is known a method for producing a fiber board material by heating and pressing at high temperature and high pressure so that the fiber chambers are integrated with each other. However, the fiber sheet produced by the above method is molded at high temperature and high pressure, which causes the decomposition of the polymer material, which is a fiber constituent, and the inherent properties of the fiber are lost. In addition, the above-mentioned conventional methods also have a problem in that the working environment is poor and environmental pollutants are generated because they use waste islands.
이러한 선행기술의 문제점을 해결하기 위하여 본 발명자는 고융점 폴리머 섬유와 저융점 폴리머 섬유로 이루어진 웹을 상기 고융점 폴리머 섬유의 융점 이하의 온도를 갖는 열풍으로 가열하고 냉각압축롤러로 냉각압축하는 가열-냉각압축공정을 다단계로 수행하여 섬유의 고유특성을 유지하면서 물성이 우수한 폴리에스테르 섬유 판재를 제조하는 방법을 개발한 바 있다. In order to solve the problems of the prior art, the present inventors heat a web made of a high melting point polymer fiber and a low melting point polymer fiber with hot air having a temperature below the melting point of the high melting point polymer fiber, and cooling and compressing it with a cooling compression roller. It has been developed a method of producing a polyester fiber sheet having excellent physical properties while maintaining the intrinsic properties of the fiber by performing the cooling compression process in multiple stages.
최근 이러한 섬유판재가 호평을 받으면서 수요자들은 두께가 보다 얇고 밀도 및 강도가 보다 높은 섬유판재에 대한 요구가 날로 증가하고 있는 추세에 있다.Recently, as the fiber board material has been well received, the demand for the fiber board material having a thinner thickness, higher density and strength is increasing day by day.
이러한 특성의 섬유판재는 프레스 회수를 늘리고 프레스압력을 하류의 프레스 공정으로 갈수록 점증적으로 증가시키는 것에 의해 제조할 수도 있을 것이나 이러한 방식을 채택하여 소망하는 정도의 두께, 밀도 및 강도를 달성하기 위해서는 기존의 견면제조용 프레스롤의 수보다 수배 이상 증가시켜야 하므로 장치가 거대해지고, 설치공간 또한 대폭 확장하여야 하므로, 생산원가의 과도한 상승이 불가피하게 된다. Fibreboard material of this nature may be manufactured by increasing the number of presses and increasing the press pressure gradually to the downstream press process, but in order to achieve the desired thickness, density and strength by adopting this method, Since the apparatus has to be increased by several times more than the number of press manufacturing rolls, the installation space has to be greatly expanded, and an excessive increase in production cost is inevitable.
뿐만 아니라 상기한 종래의 섬유판재들은 시공벽면이 평탄하지 않으면 시공벽면에 접착제를 개재하여 붙일 경우 섬유판재가 시공벽면에 충분히 밀착,결합되지 않아 시공벽면에서 떨어지기 쉽고 벽면과 판재 사이에 공간이 생겨서 결로 현상이 발생하기 쉬우며 또한 시공후 노출되는 판재표면에 벽지를 바를 경우 잘 들러붙지 아니하며 페인트를 도장하기가 곤란한 등의 단점이 있어 건축내장재로 적용하기에 부적합한 것이다. In addition, the above-described conventional fiberboard material is not flat enough to adhere to the construction wall surface when the construction wall surface is not flat, if the adhesive wall is attached to the construction wall surface through the adhesive, it is easy to fall off the construction wall surface, and there is a space between the wall surface and the plate Condensation is easy to occur, and it is not suitable to be applied as a building interior material because it has a disadvantage that it does not stick well and paint is difficult to apply when wallpaper is applied to the surface of the plate exposed after construction.
따라서 본 발명은 시공이 편리하고 시공벽면에 대한 밀착성이 우수하며 벽지 부착 및 도장이 용이한 표면 특성을 구비하고, 결로 방지효과가 우수하고 단열 및 방음 특성이 우수하여 건축내장재로서 유용한 섬유판재를 제공하는 것을 기술적 과제로 한다. Therefore, the present invention provides a fiber board material that is convenient for construction, has excellent adhesion to the construction wall, has a surface property that is easy to attach and paint wallpaper, has excellent condensation prevention effect, and has excellent thermal insulation and soundproofing properties. It is technical problem to do.

이하, 본 발명을 첨부도면을 보다 상세하게 설명하기로 한다.Hereinafter, the accompanying drawings will be described in more detail.
본 발명의 건축내장재용 섬유판재는 시공벽면에 부착될 저밀도 섬유층과 천이나 부착되거나 페인트가 도장될 고밀도 섬유층을 포함한다. 고밀도 섬유층(10)은 밀도가 100∼600㎏/㎥ 범위에 들어야 벽지를 부착하거나 페인트를 도장하기에 적합한 표면특성을 발현하게 되며, 저밀도 섬유층은 밀도가 20∼60㎏/㎥ 범위에 들어야 시공벽면이 고르지 않아도 이를 수용하여 시공벽면에 견고하게 결합시킬 수가 있게 되며 결로 현상을 효과적으로 방지할 수 있게 된다. 건축내장재로서 특히 바람직한 고밀도 섬유층의 밀도범위는 200∼300㎏/㎥이고, 저밀도 섬유층의 밀도범위는 25∼45㎏/㎥이다.The fiberboard material for building interior materials of the present invention includes a low density fiber layer to be attached to the construction wall surface and a high density fiber layer to be cloth or attached or painted. The high density fiber layer 10 should have a density in the range of 100 to 600 kg / m 3 to express the surface characteristics suitable for attaching wallpaper or paint, and the low density fiber layer should have a density in the range of 20 to 60 kg / m 3. Even without this unevenness can be accommodated to be firmly coupled to the construction wall surface and can effectively prevent condensation. The density range of the high density fiber layer which is especially preferable as a building interior material is 200-300 kg / m <3>, and the density range of the low density fiber layer is 25-45 kg / m <3>.
섬유층의 밀도는 그 구성 섬유에 존재하는 고융점 폴리머와 저융점 폴리머 함량과 압축정도로 조절할 수 있다. 여기서, 고융점과 저융점을 구별하는 기준은 섬유판재의 제조에서 섬유를 융착시키기 위하여 가열하는 온도가 된다. 즉, 상기 가열온도에서 용융되지 않는 폴리머가 고융점 폴리머이고, 용융되는 폴리머가 저융점 폴리머이다. The density of the fibrous layer can be controlled by the high melting point polymer and the low melting point polymer content and the degree of compression of the constituent fibers. Here, the criterion for distinguishing the high melting point and the low melting point is a temperature for heating to fuse the fibers in the manufacture of the fiberboard material. That is, the polymer that does not melt at the heating temperature is a high melting point polymer, and the polymer that is melted is a low melting point polymer.
바람직하게 고밀도 섬유층을 구성하는 섬유중 고융점 폴리머의 함량은 30-60중량%이고 저융점 폴리머의 함량은 40-70중량%이며, 저밀도 섬유층을 구성하는 섬유중 고융점 폴리머의 함량은 80-90중량%이고 저융점 폴리머의 함량은 10-20중량%이다. Preferably, the content of the high melting point polymer in the fibers constituting the high density fiber layer is 30-60% by weight, the content of the low melting point polymer is 40-70% by weight, and the content of the high melting point polymer in the fibers constituting the low density fiber layer is 80-90. By weight and low melting polymer content is 10-20% by weight.

If desired, the fiberboard of the present invention may, of course, be interposed between a third fiber layer having a different density value between these two fiber layers. Such an interlayer can be formed by controlling the content of the low melting polymer in the constituent fibers and the degree of heating and / or compression.

이와 같은 방법으로 제조한 제1/제2 섬유웹적층물을 도 2의 블록공정도에 에 나타낸 바와 같이 그 전체 표면을 내열·보온성 포지로 감싼 상태로 가열판식 핫프레스에 투입하여 저융점폴리머의 융점이상 내지 고융점 폴리머의 융점 미만의 온도에서 가열 하에 압축하고 냉각후에 포지를 분리하면 목적하는 섬유판재가 얻어지게 된다. Melting point of the low melting point polymer by injecting the first and second fibrous web laminates prepared in this manner into a hot plate type hot press with the entire surface of the first and second fibrous web laminates wrapped in a heat-resistant and heat-resistant foam as shown in FIG. The desired fiberboard material is obtained by compressing under heating at a temperature below the melting point of the above-mentioned high melting point polymer and separating the forge after cooling.
상기한 전가공 공정에서 프레스롤러에 의한 냉각압축은 하나의 프레스롤러에서 수행하거나 다수대가 직렬로 연결된 프레스롤러 군을 통과시켜 수행할 수도 있다. 특별히 제한하기 위한 것은 아니지만 프레스롤러는 냉각수가 내부에서 순환하는 냉각프레스롤러를 사용하는 것이 섬유판재의 표면특성이 보다 양호하게 되므로 바람직하다. 냉각 프레스롤러를 사용하더라도 프레스롤러 접촉부위에서 섬유적층물이 냉각되고 섬유적층물의 내부는 저융점 폴리머가 용융된 상태를 유지하도록 조절하는 것이 바람직하다. In the above pre-processing process, the cooling compression by the press roller may be performed by one press roller or by passing through a group of press rollers connected in series. Although not particularly limited, it is preferable that the press roller use a cooling press roller in which cooling water is circulated therein, so that the surface characteristics of the fiber board material become better. Even when a cold press roller is used, it is preferable that the fiber laminate is cooled at the press roller contact portion, and the inside of the fiber laminate is adjusted to maintain a low melting point polymer.
석션에 의한 냉각압축은 섬유적층물을 다수개의 통기공이 형성되고 하부에 공기흡입기가 장치된 석션판 위에 올려놓고 석션하여 행할 수 있다. 다공성 석션판 위에 놓인 섬유적층물을 석션하게 되면 공기가 섬유적층물 상부로부터 흡입되는 공기압력으로 섬유적층물이 압축되어 그 두께가 보다 얇아지면서 밀도가 높아지게 된다. Cooling compression by suction may be performed by suctioning the fibrous laminate on a suction plate formed with a plurality of vent holes and equipped with an air inhaler at the bottom. When the fiber laminate placed on the porous suction plate is suctioned, the fiber laminate is compressed by the air pressure that air is sucked from the top of the fiber laminate, and the thickness thereof becomes thinner and the density increases.
후가공공정에서 제1/제2 섬유웹적층물을 포지에 싸서 핫프레스에서 가열하에 압축하면, 가열,압축시에 용융된 폴리머가 적층물의 내,외부 전체에 걸쳐 균일하게 용융 및 융착되고, 냉각이 균일하게 되어 표면평활성이 우수한 고 품질의 섬유판재를 제조할 수 있게 되는데, 이는 시루에서 떡을 찔 때 떡살을 천으로 감싼 상태에서 찌게 되면 떡이 내,외부 전체에 걸쳐 골고루 익혀지는 것과 같은 원리가 작용하기 때문인 것으로 생각된다. 가열판식 핫프레스는 여러 개의 가열 판과 가압 수단이 장치된 것으로, 암면이나 압축목판재의 제조에 이용되고 있다. 내열,보온성 포지는 핫프레스에서의 가열압축시에 용융되거나 열분해되지 않는 소재로 만들어진 것이어야 하며, 적절한 보온성을 갖는 것이어야 한다. 포지로는 고온에서 용융되거나 열분해되지 않는 섬유로 이루어지고 보온성을 유지할 수 있는 직물 또는 부직포를 이용할 수 있다. 예를 들어 일반 폴리에스테르 포지를 사용하는 경우 그 두께가 0.5㎜ 이상인 것을 사용하는 것이 적당하다. 물론 본 발명은 상기한 포지로 제한되는 것은 아니며, 가열압축에 견딜 수 있는 내열성과 균일한 가열과 냉각을 보장할 수 있는 보온성을 갖는 것이라면 임의 두께 및 소재로 이루어진 포지라도 무방하다. 보온성이 불량한 포지를 사용하게 되면 섬유층의 내부와 외부간의 온도차이가 커져서 최종 제품의 표면균일성이 불량하게 된다. In the post-processing process, the first and second fibrous web laminates are wrapped in a forge and compressed under heating in a hot press, so that the molten polymer melts and fuses uniformly throughout the laminate and inside and outside of the laminate during heating and compression. It becomes uniform, which makes it possible to manufacture high-quality fiberboard material with excellent surface smoothness. When steaming rice cakes in steamed rice cakes, the rice cakes are cooked evenly all over the inside and outside when steamed with the cloth wrapped in cloth. It seems to be because it works. Hot plate type hot press is equipped with several heating plate and pressurizing means, and is used for manufacture of rock wool or compressed wood board material. Heat and heat resistant forge shall be made of a material which does not melt or thermally decompose when heated and compressed in a hot press, and shall have adequate heat retention. The forge may be a woven or nonwoven fabric which is composed of fibers which do not melt or pyrolyze at high temperatures and which can maintain warmth. For example, when using general polyester forge, it is suitable to use the thing whose thickness is 0.5 mm or more. Of course, the present invention is not limited to the forge described above, and may be formed of any thickness and material as long as it has heat resistance that can withstand heat compression and heat retention that can guarantee uniform heating and cooling. The use of poor thermal insulation forge increases the temperature difference between the inside and outside of the fibrous layer, resulting in poor surface uniformity of the final product.
또한 본 발명의 섬유판재는 원할 경우 핫프레스된 섬유판재에, 또는 프레스롤러에 의한 냉각압축 후에, 또는 공기석션판에 의한 냉각압축 후에 고융점 폴리머의 융점이상의 온도로 순간 가열하는 융착공정을 거치도록 할 수도 있다. 이러한 융착공정을 거친 섬유판재는 표면의 보풀이 제거되고 매끄러우며, 물이나 페인트 등을 도포되어도 표면손상이 없고 벽지를 바르거나 도장하기에 용이하고, 또한 섬유끼리의 융착으로 엉김이 강해 외부충격에 대한 저항성도 향상되는 등의 장점을 갖는다. 또한, 상기한 융착공정에서 엠보싱 또는 조각롤러 등을 사용하여 판재표면에 무늬를 형성시킬 수도 있으며, 이와 같이 무늬를 부여한 섬유판재는 미려한 외관을 나타내므로 천이나 벽지를 시공하거나 또는 페인트를 도장하지 않아도 되는 매우 경제적인 인테리어용 섬유판재로 이용할 수 있는 장점이 있다. In addition, the fibrous sheet of the present invention may be subjected to a fusion process for instantaneous heating to a temperature above the melting point of the high melting point polymer on a hot pressed fibrous sheet, or after cold compression by a press roller, or after cooling by an air suction plate. You may. The fiber board material that has undergone such a fusion process is smooth and has no fluff on the surface, no surface damage even when water or paint is applied, and it is easy to apply wallpaper or paint. It also has advantages such as improved resistance to. Further, in the above fusion process, a pattern may be formed on the surface of the plate by using an embossing or engraving roller, and the patterned fibrous plate material has a beautiful appearance so that it is not necessary to construct cloth or wallpaper or paint. There is an advantage that can be used as a very economical interior fiberboard material.
