먼저 본 발명에 따른 제1지지체를 준비한다(제1단계).First, a first support according to the present invention is prepared (first step).
상기 제1지지체는 폴리에스터, 폴리올레핀, 나일론, 폴리프로필렌 및 폴리에틸렌과 같은 고분자 물질로 이루어진 다공성 재질의 부직포로 형성된다. 필요에 의해, 상기 고분자 물질과 탄소섬유가 혼섬된 형태의 부직포를 사용할 수도 있다.The first support is formed of a porous nonwoven fabric made of a polymer material such as polyester, polyolefin, nylon, polypropylene, and polyethylene. If necessary, a nonwoven fabric of a form in which the polymer material and carbon fiber are mixed may be used.
이러한 고분자 물질로 이루어진 부직포는 멜트블로운, 스펀본드, 니들펀치 등의 방식으로 제작되게 되며, 필요에 의해 부직포 표면을 고전압장치에 의해 정전시켜 표면에 입자들이 정전기력으로 흡착되기 용이하도록 제작할 수도 있다.The nonwoven fabric made of such a polymer material may be manufactured by melt blown, spunbond, needle punch, or the like. If necessary, the nonwoven fabric may be electrostatically attracted to the surface by electrostatic force by a high voltage device.
그리고, 상기 제1지지체 상에 제1접착제를 분사한다(제2단계).Then, the first adhesive is sprayed on the first support (second step).
상기 제1접착제는 후술할 탄소나노소재 기능층을 안정적으로 고정시키기 위한 것으로, 상기 제1지지체 상으로의 균일한 도포를 위해 상기 제1지지체 상으로부터 일정 거리에서 분사하여 도포한다. 상기 제1접착제는 폴리프로필렌 접착제를 사용한다.The first adhesive is to stably fix the carbon nanomaterial functional layer, which will be described later, and is sprayed at a predetermined distance from the first support to apply uniformly onto the first support. The first adhesive uses a polypropylene adhesive.
또한, 상기 제1지지체 상에 이산화티타늄 나노튜브층을 성장시킨다. 여기에서, 이산화티타늄 나노튜브층은 상기 제1지지체 상에 수열합성 방식으로 성장되는 것이다.In addition, a titanium dioxide nanotube layer is grown on the first support. Here, the titanium dioxide nanotube layer is grown on the first support by hydrothermal synthesis.
그리고, 상기 제1접착제 상부 또는 상기 이산화티타늄 나노튜브층 상부에 탄소나노소재 기능층을 형성한다(제3단계).Then, a carbon nano material functional layer is formed on the first adhesive or on the titanium dioxide nanotube layer (step 3).
상기 탄소나노소재 기능층은 수분산 도료 100중량부에 대해 탄소나노소재 20~30중량부와 첨가제 5~10중량부를 혼합하여 상기 제1접착제 상에 균일하게 분사하여 형성한다.The carbon nano material functional layer is formed by uniformly spraying on the first adhesive by mixing 20 to 30 parts by weight of carbon nano material and 5 to 10 parts by weight of an additive with respect to 100 parts by weight of the water dispersion paint.
상기 수분산 도료는 물을 사용할 수도 있으며, 고분자의 분자량을 낮추고 친수기를 많은 수지를 사용할 수도 있다. 예컨대, 알키드수지, 아미노수지, 에폭시수지 등을 사용할 수 있다.Water may be used as the water dispersion paint, lowering the molecular weight of the polymer may be used a resin with a large number of hydrophilic groups. For example, alkyd resin, amino resin, epoxy resin and the like can be used.
상기 탄소나노소재는 그라핀나노플레이트(Graphene nanoplate), 다중벽탄소나노튜브(Multi-walled carbon nanotube) 및 그라핀산화물(Graphene oxide) 중 어느 하나를 사용한다.The carbon nano material may use any one of graphene nanoplates, multi-walled carbon nanotubes, and graphene oxides.
이러한 상기 탄소나노소재는, 상기 제1지지체 1mm2 당 9mg~18mg를 사용하는 것이 바람직하다. 이보다 많은 양을 사용할 경우 건조 후 탄소나노소재가 비산할 가능성이 높고, 흡착 효율이 더 이상 높아지지 않게 되거나, 필터링 효율을 떨어뜨리게 된다. 또한, 이보다 적은 양을 사용할 경우 흡착 효과가 미비하게 된다.The carbon nano material is preferably used 9mg ~ 18mg per 1mm 2 of the first support. If a larger amount is used, the carbon nanomaterial is likely to scatter after drying, and the adsorption efficiency is no longer increased or the filtering efficiency is lowered. In addition, the use of less than this, the adsorption effect is insufficient.
이러한 탄소나노소재는 넓은 활성화 비표면적과 소수성 특성을 가지고 있어, 배기가스 성분의 흡착 효율을 향상시키고, 실내외 온도차에 의해서도 낮은 젖음성 특성을 가져 필터의 수명을 향상시키게 된다.These carbon nanomaterials have a wide activation specific surface area and hydrophobic properties, thereby improving the adsorption efficiency of the exhaust gas components, and having a low wettability characteristic due to a temperature difference between indoor and outdoor, thereby improving the life of the filter.
상기 첨가제는 이산화티타늄 나노분말(TiO2 nanopowder) 또는 이산화티타늄 나노튜브(TiO2 nanotube)를 사용한다.The additive uses titanium dioxide nanopowder (TiO 2 nanopowder) or titanium dioxide nanotube (TiO 2 nanotube).
상기 첨가제로 사용되는 이산화티타늄 나노튜브는 티타늄(Ti) 호일을 양극 산화하여 형성시킨 것으로, 산 수용액에 티타늄(Ti) 호일(양극) 및 백금(Pt) 전극(음극)을 침지시켜 전압을 인가하여 양극 산화시키는 것으로서, 양극 산화 반응 종료 후 세척 및 건조하여, 열처리를 수행한다. 열처리가 종료된 후에는, 칼을 이용해 티타늄 호일 표면을 긁어 이산화티타늄 나노튜브를 얻을 수 있다. 이러한 이산화티타늄 나노튜브는 이산화티타늄 나노분말에 비해서 표면적이 넓은 특징이 있다.Titanium dioxide nanotubes used as the additive are formed by anodizing titanium (Ti) foil, and applying voltage by immersing titanium (Ti) foil (anode) and platinum (Pt) electrode (cathode) in an acid solution. As anodizing, washing and drying after completion of the anodic oxidation reaction are performed for heat treatment. After the heat treatment is finished, titanium dioxide nanotubes can be obtained by scraping the surface of the titanium foil with a knife. Such titanium dioxide nanotubes have a broad surface area as compared to titanium dioxide nanopowders.
즉, 상기 탄소나노소재 또는 상기 탄소나노소재와 상기 첨가제로 양극산화하여 형성한 이산화티타늄 나노튜브를 함께 혼합하여, 수분산 도료에 분산시켜 상기 제1접착제 상부 또는 수열합성 방식으로 성장한 이산화티타늄 나노튜브 상부에 도포하는 것으로서, 이산화티타늄의 광촉매 효과와, 유해가스를 거의 제거할 수 있으며, 항균성능을 가질 뿐 아니라 흡착 및 탈취 기능도 발휘할 수 있도록 하는 것이다.That is, the titanium dioxide nanotubes formed by mixing together the carbon nanomaterials or the carbon nanomaterials and the titanium dioxide nanotubes formed by anodizing with the additives, dispersed in an aqueous dispersion paint, and grown on the first adhesive or in a hydrothermal synthesis method. By coating on the upper side, it is possible to almost eliminate the photocatalytic effect of titanium dioxide and harmful gases, and to exhibit the adsorption and deodorization function as well as the antibacterial performance.
일반적으로 이산화티타늄은 유전율이 높은 특징을 가지고 있어 높은 정전기력 성능과 백색광(100mW/cm2) 조사 아래 광촉매 특성을 가지며, 특히, 양극산화에 의해 형성된 이산화티타늄 나노튜브를 첨가제로 하여 탄소나노소재와 함께 자동차용 캐빈에어필터에 적용함으로써, 그 표면적의 증가로 광촉매, 유해가스 제거, 항균성능, 흡착 및 탈취 효율이 더욱 우수한 특징을 갖도록 하는 것이다.In general, titanium dioxide has a high dielectric constant and has high electrostatic performance and photocatalytic properties under white light (100 mW / cm 2 ) irradiation. By applying it to the cabin air filter for automobiles, the surface area is increased so that the photocatalyst, harmful gas removal, antibacterial performance, adsorption and deodorization efficiency are more excellent.
또한, 제1지지체 상에 수열합성 방식으로 이산화티타늄 나노튜브층을 형성하고, 그 상부에 양극산화에 의해 합성된 이산화티타늄 나노튜브를 탄소나노소재 기능층의 첨가제로 사용함으로써, 상기의 특징에 대한 효과가 배가 되도록 한 것이다.In addition, by forming a titanium dioxide nanotube layer on the first support by a hydrothermal synthesis method, using titanium dioxide nanotubes synthesized by anodization on top thereof as an additive of the functional layer of carbon nanomaterial, The effect is doubled.
그리고, 상기 탄소나노소재 기능층 상에 제2접착제를 분사한다(제4단계). 상기 제2접착제는 상기 제1접착제와 동일한 재료를 사용하며, 균일한 도포를 위해 상기 탄소나노소재 기능층 상에서 일정 거리에서 분사하여 도포한다.Then, the second adhesive is sprayed on the carbon nano material functional layer (fourth step). The second adhesive is made of the same material as the first adhesive, and is applied by spraying at a predetermined distance on the carbon nano material functional layer for uniform coating.
그리고, 상기 제2접착제 상에 제2지지체를 위치시키고, 상기 제1지지체와 상기 제2지지체를 합지시켜(laminating) 본 발명에 따른 탄소나노소재가 적용된 캐빈에어필터를 제공하게 된다(제5단계).In addition, a second support is placed on the second adhesive, and the first support and the second support are laminated to provide a cabin air filter to which a carbon nano material according to the present invention is applied. ).
상기 제2지지체는 상기 제1지지체의 설명과 동일하며, 상기 제2접착제가 굳기 전에 상기 제2지지체를 덮어 라미네이팅하여, 그 사이에 탄소나노소재 기능층이 구현된 제1지지체와 제2지지체를 합지시키게 된다.The second support is the same as the description of the first support, and before the second adhesive is hardened by covering the second support and laminating, between the first support and the second support having a carbon nano material functional layer implemented therebetween. Will be combined.
