Description
본 발명은 준불연성과, 방염성과, 난연성을 만족하는 폐섬유를 이용한 난연성 가구 및 실내가구용 패널에 관한 것으로, 보다 상세하게는 폐섬유를 이용한 초지패널을 메인패널의 양면에 부착시켜 준불연성과 방염성 및 난연성을 만족시키고, 또한 요소수지에 아산화구리가 첨가된 항균액에 함침된 LPM시트를 초지패널에 부착시켜 항균성을 갖도록 한 폐섬유를 이용한 난연성 가구 및 실내가구용 패널에 관한 것이다.The present invention relates to flame-retardant furniture and indoor furniture panels using waste fiber that satisfies semi-incombustibility, flame retardancy, and flame retardancy. More specifically, papermaking panels using waste fiber are attached to both sides of the main panel to provide semi-incombustibility and flame retardancy. and flame retardant furniture and indoor furniture panels using waste fiber that satisfy flame retardancy and have antibacterial properties by attaching LPM sheets impregnated with an antibacterial solution containing cuprous oxide added to urea resin to papermaking panels.
통상적으로 실내 가구용 패널은 건물 실내에 신발장, 붙박이장, 화장대, 거실장, 수납장, 진열장 형태로 시공된다.Typically, indoor furniture panels are installed inside buildings in the form of shoe cabinets, built-in closets, dressers, living room cabinets, storage cabinets, and display cases.
이러한 실내 가구용 패널은 최근 원목 사용에 따른 가격적인 부담을 고려하여 합성목재 판재를 이용하여 제작된다.These indoor furniture panels are manufactured using synthetic wood boards, taking into account the recent cost burden of using solid wood.

한편 본 발명의 초지패널(20)을 상세히 설명하기에 앞서, 일반적으로 초지패널(20)은 섬유재를 사용하여 제조된 초지를 제조하는 초지 공정과, 상기 초지 공정에 의해 수득된 초지를 함침조성물에 함침한 후 이를 열압착 성형함으로써 제조되는데, 난연성을 부여하기 위하여 상기 함침조성물에 난연제를 첨가하여 가공할 수 있다.Meanwhile, before describing the
본 발명의 초지패널(20)은 이러한 종래의 초지패널을 제조하기 위한 함침조성물의 성분을 최적화함으로써 난연제 성분이 초지패널에 고분산되어 난연성을 향상시킬 수 있도록 하는 것을 기술적 특징으로 한다.The
상기 함침조성물에 함유되는 난연제로는 트리페닐포스페이트, 수산화알루미늄 및 데카브로모디페닐에탄의 3가지 성분으로 이루어진 난연제를 적용하고 있는데, 상기 난연제의 조합에 의해 초지패널의 난연성능을 향상시킬 수 있는 것으로 나타났다.As a flame retardant contained in the impregnation composition, a flame retardant consisting of three components, triphenyl phosphate, aluminum hydroxide, and decabromodiphenylethane, is applied. The flame retardant performance of the papermaking panel can be improved by the combination of the above flame retardants. appear.
특히, 상기 난연제의 각 성분을 적절한 비율로 혼합하면 초지 조성물을 구성하는 성분들과의 상용성을 높일 수 있기 때문에 난연제의 함량을 높이더라도 함침 공정이 원활히 이루어지는 것으로 나타나 일반적인 함침 공정에 비해 더 많은 양의 난연제를 함침시킬 수 있는 것으로 나타났다.In particular, mixing each component of the flame retardant in an appropriate ratio can increase compatibility with the components constituting the papermaking composition. Therefore, even if the content of the flame retardant is increased, the impregnation process appears to be carried out smoothly. Compared to the general impregnation process, the impregnation process appears to be smooth. It has been shown that it can be impregnated with flame retardants.
상기 함침조성물을 구성하는 난연제는 구체적으로 트리페닐포스페이트 20 내지 30중량%, 수산화알루미늄 50 내지 60중량% 및 데카브로모디페닐에탄 10 내지 20중량%로 이루어진 난연제를 사용하는데, 이를 통해 인계 난연제인 트리페닐포스페이트나 브롬계 난연제인 데카브로모디페닐에탄으로 인한 응집이 발생하지 않으면서도 함침 공정시 양호한 분산성을 확보할 수 있게 된다.The flame retardant constituting the impregnating composition is specifically a flame retardant consisting of 20 to 30% by weight of triphenyl phosphate, 50 to 60% by weight of aluminum hydroxide, and 10 to 20% by weight of decabromodiphenylethane, through which the phosphorus-based flame retardant, tri Good dispersibility can be secured during the impregnation process without agglomeration occurring due to phenyl phosphate or decabromodiphenylethane, a brominated flame retardant.
또한, 상기 난연제를 구성하는 수산화알루미늄은 난연 효과뿐만 아니라 초지를 구성하는 섬유재의 친수성을 높여 결합력을 향상시킬 수 있게 한다.In addition, aluminum hydroxide, which constitutes the flame retardant, not only has a flame retardant effect, but also improves bonding strength by increasing the hydrophilicity of the fiber material making up the paper.
상기 난연제를 구성하는 각 성분들은 50 내지 150㎛의 입도로 분급하여 사용하는 것이 바람직한데, 이는 초지를 구성하는 섬유재 내에서의 분산성을 감안한 것으로서, 입도가 너무 작은 경우 함침 공정에서 섬유재 내에 분산되지 않는 미반응 분말의 발생량이 증가하며 너무 큰 경우에도 충분한 함침이 이루어지지 않기 때문에 상기 크기 범위가 되도록 분급하여 사용하는 것이 바람직하다.It is preferable to use each component constituting the flame retardant by classifying it into a particle size of 50 to 150㎛. This is taken into consideration the dispersibility within the fiber material constituting the papermaking, and if the particle size is too small, it may be contained within the fiber material during the impregnation process. Since the amount of unreacted powder that is not dispersed increases and sufficient impregnation is not achieved even if it is too large, it is preferable to classify and use it so that it falls within the above size range.
또한, 상기 함침조성물에는 실리카가 함유되는데, 특히, 폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트의 공중합체로 표면처리된 실리카를 사용함으로써 난연제의 분산성과 성형성을 향상시키고 있다. 상기 폴리메틸메타크릴레이트 공중합체는 실리카 입자와 그래프트 공중합함으로써 표면처리된 실리카 입자를 형성하게 된다.In addition, the impregnation composition contains silica. In particular, the dispersibility and moldability of the flame retardant are improved by using silica surface-treated with a copolymer of polybutylacrylate and polymethyl methacrylate. The polymethyl methacrylate copolymer is graft-copolymerized with silica particles to form surface-treated silica particles.
이러한 표면처리된 실리카 입자는 일종의 분산제 역할을 하면서도 공중합체의 말단에 결합되는 실리카의 친수성으로 인해 초지를 구성하는 섬유재 내에서 난연제가 빠르게 분산되어 흡착을 촉진할 수 있도록 하는 것으로 나타났다.These surface-treated silica particles act as a kind of dispersant, and due to the hydrophilic nature of silica bonded to the end of the copolymer, it has been shown that the flame retardant is quickly dispersed within the fiber material that makes up the paper and promotes adsorption.
폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트의 공중합체는 부틸아크릴레이트와 메틸메타크릴레이트가 1:1의 중량비로 함유된 공중합체의 경우 코팅제로 사용되며, 부틸아크릴레이트 함량이 90중량% 이상인 경우에는 접착제로 사용될 수 있는 것으로 알려져 있다. 즉, 상기 공중합체의 물성은 공중합체의 조성비에 의해 달라질 수 있다.Copolymers of polybutylacrylate and polymethyl methacrylate are used as coating agents in the case of copolymers containing butylacrylate and methyl methacrylate in a weight ratio of 1:1, and when the butylacrylate content is more than 90% by weight. It is known that it can be used as an adhesive. That is, the physical properties of the copolymer may vary depending on the composition ratio of the copolymer.
본 발명에서는 상기 폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트의 공중합체로서, 폴리부틸아크릴레이트 10 내지 20중량% 및 폴리메틸메타크릴레이트 80 내지 90중량%로 조성된 공중합체를 사용하고 있다. 또한, 상기 공중합체에 실리카를 부가하여 그래프트 공중합체를 형성하기 위하여 상기 폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트의 공중합체 80 내지 90 몰%에 01 내지 05㎛의 실리카 입자 10 내지 20 몰%가 되도록 공중합체와 실리카 입자를 혼합하고 그래프트 공중합체하여 표면처리된 실리카를 제조할 수 있다.In the present invention, as a copolymer of polybutylacrylate and polymethyl methacrylate, a copolymer composed of 10 to 20% by weight of polybutylacrylate and 80 to 90% by weight of polymethyl methacrylate is used. In addition, in order to form a graft copolymer by adding silica to the copolymer, 10 to 20 mol% of 01 to 05㎛ silica particles are added to 80 to 90 mol% of the copolymer of polybutylacrylate and polymethyl methacrylate. Surface-treated silica can be produced by mixing the copolymer and silica particles as much as possible and grafting the copolymer.
즉, 상기 함침조성물은 폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트의 공중합체를 제조하는 단계, 상기 공중합체에 실리카 입자를 혼합하여 표면처리된 실리카를 제조하는 단계, 상기 실리카에 난연제를 혼합하는 단계를 포함하여 제조될 수 있다.That is, the impregnation composition includes the steps of preparing a copolymer of polybutylacrylate and polymethyl methacrylate, mixing silica particles into the copolymer to prepare surface-treated silica, and mixing a flame retardant into the silica. It can be manufactured including.
또한, 상기 함침조성물은 폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트 공중합체 30 내지 40 중량부, 표면처리된 실리카 10 내지 20 중량부 및 난연제 50 내지 60 중량부로 이루어지며, 원활한 함침을 위해 물 50 내지 200 중량부를 부가하여 수용액을 형성하여 사용하게 된다. 또한, 상기 초지패널에 색상을 부여하기 위하여 상기 함침조성물을 제조하는 과정에서 무기안료를 첨가할 수도 있다.In addition, the impregnation composition consists of 30 to 40 parts by weight of polybutylacrylate and polymethyl methacrylate copolymer, 10 to 20 parts by weight of surface-treated silica, and 50 to 60 parts by weight of a flame retardant, and 50 to 60 parts by weight of water for smooth impregnation. It is used by adding 200 parts by weight to form an aqueous solution. Additionally, in order to impart color to the papermaking panel, an inorganic pigment may be added during the process of manufacturing the impregnation composition.
상기 표면처리된 실리카 입자는 폴리부틸아크릴레이트와 실리카 입자를 브롬화 구리(CuBr2) 및 아스코르브산의 존재하에 반응시켜 폴리부틸아크릴레이트로 표면처리된 실리카 입자를 제조하고, 상기 실리카 입자에 다시 메틸메타크릴레이트를 부가하고 브롬화 구리 존재하에 반응시켜 폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트 공중합체가 실리카 입자를 표면처리한 형태의 실리카를 수득할 수 있다. The surface-treated silica particles are prepared by reacting polybutylacrylate and silica particles in the presence of copper bromide (CuBr2) and ascorbic acid to prepare silica particles surface-treated with polybutylacrylate, and methyl methacrylic is added to the silica particles again. By adding a rate and reacting in the presence of copper bromide, silica in the form of polybutylacrylate and polymethyl methacrylate copolymer surface-treated silica particles can be obtained.
이후, 제조된 실리카에 난연제를 부가하여 교반함으로써 함침조성물을 수득하게 된다.Thereafter, a flame retardant is added to the prepared silica and stirred to obtain an impregnation composition.
상기와 같이 수득된 함침조성물에 초지를 함침시키는데, 상기 초지는 폐섬유를 포함하는 섬유재를 사용하여 통상의 초지 제조공정을 적용함으로써 수득될 수 있다.Paper is impregnated with the impregnating composition obtained as above, and the paper can be obtained by applying a normal papermaking process using a fiber material containing waste fibers.
대한민국 공개특허공보 10-2018-0107524호에서는 준불연 초지 섬유판재를 제조하기 위하여 초지 공정에서 난연제를 함유하는 초지 조성물과 섬유재를 섞어 초지를 제조하고 있으며, 제조된 초지를 다시 난연제가 함유된 함침조성물에 함침시키는 공정을 적용하고 있다. 이러한 두 차례의 난연제 도입에 의해 초지 내부에 난연제의 함량을 늘일 수는 있으나, 초지 제조공정에서 난연제가 함유되면 초지 자체의 내구성이 저하되어 공정 불량이 발생하게 되는 문제점이 있다.In Korean Patent Publication No. 10-2018-0107524, papermaking is made by mixing a papermaking composition containing a flame retardant with a fiber material in the papermaking process to produce a semi-incombustible papermaking fiberboard, and the produced paper is again impregnated with a flame retardant. A process of impregnating the composition is applied. Although it is possible to increase the content of the flame retardant inside the papermaking process by introducing the flame retardant twice, there is a problem in that if the flame retardant is included in the papermaking process, the durability of the papermaking itself decreases, resulting in process defects.
본 발명은 이러한 종래기술의 공정과는 달리 초지를 통상의 초지 공정으로 제조한 후 함침 공정만으로 초지 섬유질 내에 난연제가 도입되도록 하고 있다. 또한, 이러한 공정만으로도 충분한 난연효과를 달성할 수 있도록 함침 공정을 위한 함침조성물의 성분 및 함량을 최적화하고 있다.The present invention, unlike the process of the prior art, manufactures paper through a normal papermaking process and then introduces a flame retardant into the papermaking fibers only through an impregnation process. In addition, the ingredients and content of the impregnation composition for the impregnation process are being optimized so that sufficient flame retardant effect can be achieved through this process alone.
상기 섬유재는 폐섬유를 이용하는데, 상기 폐섬유는 면, 펄프, 폴리에스테르, 폴리프로펠렌에서 선택된 천연섬유나 합성섬유를 단독으로 사용할 수도 있고 또는 혼합된 섬유를 사용할 수도 있다. 또한, 폐섬유와 일반섬유를 혼합하여 사용할 수도 있다.The fiber material uses waste fibers. The waste fibers may be natural fibers or synthetic fibers selected from cotton, pulp, polyester, and polypropylene, or may be used as mixed fibers. Additionally, waste fibers and regular fibers can be mixed and used.
또한, 상기 섬유재를 이용하여 초지 공정을 수행하기에 앞서 비팅(beating) 공정을 통해 섬유재를 연마 처리할 수 있다. 상기 비팅 공정에서는 섬유재를 미세한 분말 형태로 분쇄한 후 수조에 투입하여 2 내지 3시간 동안 연마하게 된다.Additionally, prior to performing a papermaking process using the fiber material, the fiber material may be polished through a beating process. In the beating process, the fiber material is ground into a fine powder, placed in a water bath, and polished for 2 to 3 hours.
이와 같이 연마 처리된 섬유재를 이용하여 초지를 제조하는데, 섬유재를 탈수 건조하는 공정이며, 지층형성, 압착탈수, 건조, 표면처리 등의 통상의 초지 공정을 적용할 수 있다. 즉, 헤드박스에서 분출된 섬유재를 와이어부에 도입하여 지필로 형성된 다음, 압착부에서 압착 탈수 과정을 거치며, 건조부에서 잔류수분을 증발시킨 다음 캘린더에서 종이의 두께가 조절되어 초지로 완성된다.In this way, papermaking is made using the polished fiber material, which is a process of dehydrating and drying the fiber material, and normal papermaking processes such as stratum formation, compression dehydration, drying, and surface treatment can be applied. In other words, the fiber material ejected from the head box is introduced into the wire section to form paper, then goes through a pressing and dehydration process in the pressing section, the remaining moisture is evaporated in the drying section, and then the thickness of the paper is adjusted in the calendar to complete the paper making process. .
상기 초지는 두께가 1 내지 5㎜가 되도록 제조할 수 있다. 초지의 두께가 너무 두꺼우면 이후 함침 공정에서 난연제의 함침이 원활하지 않으며 두께가 너무 얇으면 후공정에서 초지의 손상이 발생할 수 있기 때문에 상기 두께 범위가 되도록 제조하는 것이 바람직하다.The paper can be manufactured to have a thickness of 1 to 5 mm. If the thickness of the paper is too thick, impregnation of the flame retardant in the subsequent impregnation process will not be smooth, and if the thickness is too thin, damage to the paper may occur in the subsequent process, so it is preferable to manufacture it so that it falls within the above thickness range.
상기 함침 공정은 상기 함침조성물이 수납된 함침조에 상기 초지를 투입하고 상기 함침조 내에 설치된 압축 가이드 롤러를 거치면서 함침시킨 후 스틸 압축 롤러로 가압함으로써 초지의 수분 함량을 줄이면서 함침 과정을 진행할 수 있다. 또한, 초지를 구성하는 섬유질 내에 함침조성물의 성분이 침투할 수 있도록, 상기 가이드 롤러로 음각 및 양각으로 만든 롤러를 사용하여 가압하면서 함침되도록 할 수도 있고, 상기 함침 공정 후 수득된 난연성 초지패널을 건조하는 공정을 수행할 수 있다.The impregnation process involves putting the paper into an impregnation tank containing the impregnation composition, impregnating it while passing through a compression guide roller installed in the impregnation tank, and then pressurizing it with a steel compression roller to proceed with the impregnation process while reducing the moisture content of the paper. . In addition, so that the components of the impregnating composition can penetrate into the fibers constituting the papermaking, it can be impregnated while pressing using a roller made of engraving and embossing as the guide roller, and drying the flame-retardant papermaking panel obtained after the impregnation process. The process can be performed.
또한, 상기 난연성 초지패널을 열압착기를 이용하여 열압착 성형할n수 있다. 상기 열압착 성형은 평면 열압착 성형이며 이를 통해 초지를 구성하는 섬유질의 평활도와 안정성을 유지할 수 있다. 상기 열압착 성형 공정을 수행할 때 상기 열압착기의 상단에 금형을 부착하여 상기 난연성 초지패널의 표면에 다양한 문양을 형성할 수도 있다.Additionally, the flame-retardant papermaking panel can be thermo-compressed and molded using a thermo-compressor. The thermocompression molding is a flat thermocompression molding, through which the smoothness and stability of the fibers that make up the papermaking can be maintained. When performing the thermocompression molding process, a mold may be attached to the top of the thermocompressor to form various patterns on the surface of the flame-retardant papermaking panel.
이러한 열압착 성형을 하거나 또는 건조된 난연성 초지패널을 2매 이상의 합지하는 합지 공정을 수행함으로써 합지된 판재 또는 보드 형태로 제조할 수 있다. 상지 합지 공정은 상기 난연성 초지패널의 용도에 따라 2 내지 6매의 범위에서 적층하여 합지할 수 있다. 또한, 상기 합지 공정을 위하여 합지할 난연성 초지 패녈의 표면에 접착제를 도포한 후 적층하여 접착할 수 있다. 이와 같이 합지공정을 수행하면 두께가 2 내지 30㎜가 되도록 조절할 수 있으므로 각종 실내 가구용 소재로 사용할 수 있다.It can be manufactured in the form of a laminated sheet or board by performing such thermocompression molding or performing a lamination process of lamination of two or more dried flame-retardant papermaking panels. The upper paper lamination process may be performed by stacking 2 to 6 sheets depending on the use of the flame-retardant papermaking panel. In addition, for the above lamination process, adhesive can be applied to the surface of the flame-retardant papermaking panel to be laminated and then laminated to adhere. If the lamination process is performed in this way, the thickness can be adjusted to 2 to 30 mm, so it can be used as a material for various indoor furniture.

This was pressed and dehydrated in the pressing section, the remaining moisture was evaporated in the drying section, and then passed through a calendar to produce paper with a width of 1,000 mm, a length of 2,500 mm, and a thickness of 2 to 25 mm.
상기 초지를 함침조성물이 저장된 함침조에 투입하였으며, 함침조 내에 설치된 가이드 롤러를 거쳐 스틸 압축 롤러로 가압하여 난연성 초지패널을 제조하고 1차 건조하였다. 1차 건조된 난연성 초지패널을 180℃, 200㎏/㎠의 온도와 압력으로 3분간 열압착하여 두께 2㎜의 난연성 초지패널을 수득하였다.The papermaking was put into an impregnation tank where the impregnation composition was stored, and pressurized with a steel compression roller through a guide roller installed in the impregnation tank to produce a flame-retardant papermaking panel and first dried. The first dried flame-retardant papermaking panel was heat-compressed at 180°C and a temperature and pressure of 200kg/cm2 for 3 minutes to obtain a flame-retardant papermaking panel with a thickness of 2mm.
이때, 함침액은 난연제 60 중량부, 실리카 15 중량부 및 폴리부틸아크릴레이트 및 폴리메틸메타크릴레이트의 공중합체 35 중량부로 이루어진 함침조성물을 물 100 중량부와 혼합하여 제조하였다.At this time, the impregnation solution was prepared by mixing an impregnating composition consisting of 60 parts by weight of a flame retardant, 15 parts by weight of silica, and 35 parts by weight of a copolymer of polybutylacrylate and polymethyl methacrylate with 100 parts by weight of water.
이때, 상기 난연제는 트리페닐포스페이트 24중량%, 수산화알루미늄 58중량% 및 데카브로모디페닐에탄 18중량%를 혼합하여 사용하였으며, 부틸아크릴레이트/메틸메타크릴레이트 공중합체로는 BA 15중량% 및 MMA 85중량%로 조성된 공중합체를 사용하였다.At this time, the flame retardant was used as a mixture of 24% by weight of triphenyl phosphate, 58% by weight of aluminum hydroxide, and 18% by weight of decabromodiphenylethane, and the butylacrylate/methyl methacrylate copolymer was 15% by weight of BA and 85% of MMA. A copolymer composed in weight percent was used.

비교를 위하여 실시예와 동일한 함침 공정을 실시하되 함침조성물로 액상규산칼륨 80 중량부, 울트라카브 30 중량부, 규조토 20 중량부를 물 100 중량부와 혼합한 조성물을 사용하였다.For comparison, the same impregnation process as in the example was performed, but a composition of 80 parts by weight of liquid potassium silicate, 30 parts by weight of ultracarb, and 20 parts by weight of diatomaceous earth mixed with 100 parts by weight of water was used.
실시예 및 비교예에 따른 난연성 초지패널(20)과 종래의 목재 패널에 대한 직화 연소 실험을 실시하였다. 그 결과 도 2(b)에서와 같이 실시예의 난연성 초지패널(20)은 직화 분사에도 연소되지 않아 난연성이 우수한 것으로 나타났다. 이에 대하여 비교예에 따른 난연성 초지패널(20)은 도 2(a)와 같이 난연성을 나타내어 종래의 목재 패널(도 2(c))에 비해서는 발화 정도가 약했으나 실시예에 비해 심한 것으로 나타났다. 이러한 결과는 본 발명의 함침 공정에 의해 초지패널에 난연제 성분이 다량 함유되기 때문인 것으로 판단되었다.Direct combustion experiments were conducted on the flame-
