Description
본 발명은 자동차 실내공기 여과장치, 가정 및 상업용 에어컨디셔너, 공기청정기, 공장용 공기정화기 등에서 악취물질이나 특정물질제거에 사용할 수 있는 활성탄 공기필터의 제조방법에 관한 것이다.The present invention relates to a method for producing an activated carbon air filter that can be used to remove odorous substances or specific substances in automobile indoor air filtration device, home and commercial air conditioner, air purifier, factory air purifier and the like.
환경에 관한 세계적 관심의 고조와 더불어 일상생활의 질적향상을 위한 노력이 각종 공해물질(분진, 악취)의 효율적 부리제거에 집중되괴 있다. 특히 경제성장을 주도하며 그 신장소도가 날로 증가하고 있는 승용차등 운송수단은 주행성능, 안전성, 거주성등 기본성능의 완성도가 높아짐에 따라 점차 고급화 추세에 있으며, 쾌적한 실내광간 유지에 관한 대책이 시급한 실정이다. 일정한 실내공간을 쾌적하게 유지하는 문제에 있어 주된 저해인자는 먼지 등 부유물질과 담배, 땀, 곰팡이로부터 나는 악취와 승용차의 경우 배출가스냄새, 내장재의 마감처리시 사용된 각종 용제등의 냄새를 들 수 있다. 이러한 냄새를 발생시키는 주성분은 암모니아 및 아민류의 질소계 화합물과, 톨루엔, 스틸렌, 이소프렌 등의 저급탄화 수소화합물 그리고 황화수소, 메르캅탄, 황화디메틸 등의 유황화합물이다. (일본특허공개공보 제 평4-73276호).Increasing global attention on the environment and efforts to improve the quality of daily life are concentrated on the efficient elimination of various pollutants (dust, odor). In particular, passenger vehicles such as passenger vehicles, which are leading the economic growth and increase in height, are gradually becoming more advanced as the completion of basic performance such as driving performance, safety, and occupancy is increasing, and measures to maintain pleasant indoor light are urgently needed. It is true. The main inhibitors in maintaining a comfortable interior space include dust, suspended substances such as dust, odors from cigarettes, sweat, and mold, and the smell of exhaust gases in passenger cars and various solvents used in finishing interior materials. Can be. The main constituents that generate these odors are nitrogen compounds of ammonia and amines, lower hydrocarbon compounds such as toluene, styrene and isoprene, and sulfur compounds such as hydrogen sulfide, mercaptan and dimethyl sulfide. (Japanese Patent Laid-Open No. Hei 4-73276).
이들 냄새를 방지하기 위하여 종래부터 사용되고 있는 방법으로는 방향제를 사용하여 악취를 마스킹 또는 감각적으로 중화시키는 방법 또는 액체 탈취제를 산포 또는 휘발시키는 등의 수동적인 방법들이 있어 왔지만 (일본특허공개공보 제 평4-73275 호), 이러한 수동적 냄새방지방법은 일시적인 것으로 지속적인 효과를 기대하기 어려웠으며, 또한 냄새원의 근본적인 제걱가 아니기 때문에 바람직한 탈취방법이라고는 할 수 없었다. 따라서 상기한 문제점을 해결하기 위하여 정전기등을 이용한 집진 냄새제거방법이 제시되었으나, 이 방법 역시 집진제거 장치외에 별도의 동력제공설비가 필요하며, 이들 동력원이 공급되지 않을 경우, 소망하는 효과를 기대할 수 없는 단점이 있었다.In order to prevent these odors, there have been manual methods such as masking or sensitizing neutralizing odor using fragrance, or dispersing or volatifying liquid deodorant, etc. (Japanese Patent Laid-Open Publication No. 4). -73275), this passive odor prevention method is temporary and difficult to expect a lasting effect, and it is not a desirable deodorization method because it is not a fundamental application of the odor source. Therefore, in order to solve the above problems, a dust collecting odor removing method using static electricity is proposed, but this method also requires a separate power supply facility in addition to the dust removing device, and if these power sources are not supplied, a desired effect can be expected. There were no drawbacks.
결국 이런한 문제점들과 불편을 해소하기 위하여 악취물질이나 특정물질의 흡착제거에 뛰어난 성능이 있는 활성탄을 이용한 활성탄공기필터가 제시되었는데, 활성탄이란 내부에 무수히 많은 세공(Pore)을 갖고 있는 무정질의 탄소덩어리로서, 액상 및 기상부분에서 정수, 폐수처리, 당액탈색, 자동차 캐니스터(CANISTER), 공기정화, 용제회수, 담배필터 등의 넓은 용도를 갖고 있는 우수한 흡착제로 알려져 있다.Eventually, in order to solve these problems and inconveniences, activated carbon air filters using activated carbon with excellent performance in adsorption and removal of odorous substances or specific substances have been proposed. Activated carbon is an amorphous carbon having a large number of pores therein. As agglomerates, it is known as an excellent adsorbent for a wide range of applications such as water purification, wastewater treatment, sugar liquor decolorization, automobile canisters, air purification, solvent recovery, and tobacco filters in liquid and gaseous parts.
원료는 야자각, 목탄, 톱밥, 석탄 등이 주로 사용되며, 이를 적정크기로 파쇄한 후 탄화 및 활성화공정을 거쳐 제품화된다. 탄화공정에서 원료 내부에 함유된 위발성분이나 수분 등이 가열에 의하여 외부로 빠져나가면서 일차 세공이 생성되고, 이를 다시 활성화공정에서 약품이나 수증기 등의 혼합가스와 탄소가 화학반응하여 더욱 많은 세공이 발달 생성된다. 생성된 세공은 IUPAC (International Union of Pure and Applied Chemistry)정의에 따라, 마이크로포어 (Micropore) (세공직경 : 18Å이하), 메조포어 (Mesopore) (18Å∼500Å), 마크로포어 (Micropore) (500Å이상)로 각각 분류하였는데, 악취물질의 흡착에 주로 기여하는 부분은 마이크로포어 (Micropore) 및 메조포어 (Mesopore)영역으로 알려져 있다. (미국특허공보 제 5204310호). 한편, 활성탄은 형태에 따라 파쇄(입상), 조립, 분말로 각각 분류된다.The raw materials are coconut shell, charcoal, sawdust, coal, etc., which are crushed to an appropriate size, and then carbonized and activated to be commercialized. In the carbonization process, primary pores are generated as the gastric components and moisture contained in the inside of the raw material are released to the outside by heating, and in the activation process, the mixed gas such as chemicals or water vapor and carbon react with each other to produce more pores. Development is produced. The resulting pores were defined as IUPAC (International Union of Pure and Applied Chemistry), Micropore (pore diameter: 18Å or less), Mesopore (18Å ~ 500Å), Macropore (500Å or more) The major contributions to adsorption of malodorous substances are known as the micropore and mesopore regions. (US Patent Publication No. 5204310). On the other hand, activated carbon is classified into crushed (granular), granulated and powder depending on the form.
상기의 활성탄을 사용한 종래의 활성탄 공기필터의 제조방법으로는 활성탄과 고분자계의 접착제등을 혼합하여 벌집형태로 압출 성형시키는 방법(일본특허공개공보 제 평1-184346호, 독일공개공보 제 2148736 호, 제 2110561 호, 유럽특허공개공보 제 526077 호), 활성탄을 부직포동에 열융착시퓔는 방법 (일본특허공개공보 제 평5-76724 호, 대한민국 특허공고공보 제 1982-708 호, 제 1984-1248 호, 제 1984-1247 호) 및 고무계나 비닐계 등의 접착제를 선정하여 부직포나 3차원의 망상 시트류에 활성탄을 접합시키는 방법 (일본특허공개공보 제 소47-3275 흐, 제 소47-3276 호, 제 소48-34398 호, 대한민국 특허공고공보 제 1933-4693 호)이 있다. 이외 피치 (PITCH) 계 혹은 팬(PAN)계의 고분자를 사용하여 제조한 활성탄섬유(Activated Carbon Fiber : 일본특허공개공보 제 소63-137721호, 미국특허공보 제 5215690 호, 제 5204310 호, 유럽특허출원 제 92110338.8 호) 도 제시되고 있다.Conventional methods of manufacturing activated carbon air filters using the activated carbon include a method of mixing activated carbon with an adhesive of a polymeric system and extruding it into a honeycomb form (Japanese Patent Laid-Open Publication No. Hei 1-1 84346 and German Publication 2148736). , 2110561, European Patent Publication No. 526077), Method of thermally fusion activated carbon to nonwoven fabrics (Japanese Patent Publication No. Hei 5-76724, Korean Patent Publication No. 1982-708, 1984-1248 No. 1984-1247) and a method of joining activated carbon to non-woven fabrics or three-dimensional network sheets by selecting an adhesive such as rubber or vinyl (JP-A-47-3275H, No. 47-3276). No. 48-34398, Korean Patent Publication No. 1933-4693). In addition, activated carbon fiber manufactured using a PITCH-based or PAN-based polymer (Japanese Patent Laid-Open No. 63-137721, US Patent No. 5215690, 5204310, European Patent) Application 92110338.8) is also presented.
전자인 벌집형상의 압출성형방법의 경우, 활성탄이 가지고 있는 흡착능을 최대로 이용할 수 있다는 장점이 있으나, 벌집상의 성형의 기술적인 어려움과이에 따른 경제성의 문제 그리고 아울러 압력손실이 큰 문제와 적용범위 한계 때문에 특별한 장치가 필요하다는 단점이 있다.The former honeycomb extrusion method has the advantage of using the adsorption capacity of activated carbon to the maximum, but the technical difficulties in forming the honeycomb and the resulting economical problems, as well as the large pressure loss and the scope of application Because of this, a special device is required.
후자의 열융착시키는 방법의 경우, 부직포등에 가열 처리하므로써 원형의 파괴, 흡착제의 열적변형과 아울러 접착제의 변질에 따른 성능저하가 우려되고, 또한 부착력이 약해 활성탄이 탈리되는 단점이 있다. 또한 피치계 혹은 팬계의 고분자를 사용한 활성탄섬유 필터의 경우에는 흡착능력 및 압력손실등에 좋은 성능을 나타내는 반면 전량수입되고 있으며 고가인 문제점이 있다.In the latter method of thermal fusion, the heat treatment of a nonwoven fabric or the like causes the destruction of the circle, the thermal deformation of the adsorbent, and the deterioration of the performance due to the deterioration of the adhesive. In addition, the activated carbon fiber filter using the polymer of the pitch system or the fan system shows good performances such as adsorption capacity and pressure loss, while importing all of them and having a high price.
따라서 본 발명은 상기한 바와 같은 선행기술에서의 제반 문제점을 해결하기 위하여 열적변형이 적으며 흡착력이 높고 압력손실이 적은 저가의 활성탄 공기필터의 제조방법의 제공을 목적으로 한다.Accordingly, an object of the present invention is to provide a method of manufacturing a low-cost activated carbon air filter having low thermal deformation, high adsorption force, and low pressure loss in order to solve the problems in the prior art as described above.
상기한 목적을 달성하기 위하여 제공되는 본 발명의 공기정화용 활성탄필터의 제조방법은 망사모양의 3차원 구조를 갖는 폴리우레탄 폼(foam)을 모재로 사용하고 0.590mm 이하의 활성탄분말을 접착제를 사용하여 상기 모재에 접착 고정시키는 공정으로 구성됨을 특징으로 하여 활성탄이 지니고 있는 흡착능을 최대로 유지하고자 하였다.In order to achieve the above object, the present invention provides a method for producing an activated carbon filter for purifying air, which uses a polyurethane foam having a mesh-shaped three-dimensional structure as a base material and an activated carbon powder of 0.590 mm or less using an adhesive. It was intended to maintain the adsorption capacity of the activated carbon to the maximum, characterized in that it consists of a process of fixing to the base material.
본 발명의 공기정화용 활성탄 필터의 제조방법은 다음과 같은 단계들로 구성되는 것을 특징으로 한다.The manufacturing method of the activated carbon filter for air purification of this invention is characterized by consisting of the following steps.
1) 접착제와 활성탄분말을 혼합하여 에멀젼용액을 제조하는 단계1) preparing an emulsion solution by mixing the adhesive and activated carbon powder
2) 상기 에멀젼용액에 폴리우레탄폼을 함침시키고 압착롤러를 이용하여 압착도포하는 단계2) impregnating the polyurethane foam in the emulsion solution and pressing the coating using a pressing roller
3) 1차 압착도포된 활성탄필터에 활성탄 분말을 2차 압착도포하는 단계. 단, 2차도포를 거쳐 제조된 제품들은 적용시 제품에서 부분적인 탈리가 있을 수 있기 때문에 2차도포과정은 생략할 수도 있으며 활성탄 분말도포대신 1)의 에멀젼용액을 재도포할 수도 있다.3) applying activated carbon powder to the first compressed coated carbon filter. However, the products manufactured through the secondary coating may be partially detached from the product when applied, so the secondary coating process may be omitted, and instead of the activated carbon powder coating, the emulsion solution of 1) may be reapplied.
4) 함침 및 도포를 거쳐 제조된 활성탄 공기필터를 건조시키는 단계4) drying the activated carbon air filter manufactured through impregnation and application
한편, 활성탄의 흡착력은 세공의 크기 및 총 표면적에 따라 결정되는 특성상 활성탄 필터 제조시에는 상기 세공들을 차폐하지 아니하는 접착제를 선정하여야 하므로 액체에 접착성분의 고분자분말이 균일하게 분산되어 있고 상기 입자의 크기가 활성탄의 세공보다 큰 에멀젼 형태의 접착제가 선정 사용되는데, 본 발명에서는 수성계 접착제인 EVA (ethylene vinyl acetate)계 접착제가 사용된다. 또한 세공에 에멀젼 용액의 미세입자가 충전되는 것을 방지하고 제조된 필터의 유연서을 제공하기 위하여 활성탄분말과의 혼합에 앞서 조제로서 CMC (carboxy methyl cellulose) 및/또는 PVA (polyvinyl alcohol)을 상기 접착제에 혼합사용하는 것이 바람직하다. 활성탄 분말과접착제로 에멀젼용액을 제조할 때 이들의 배합비율은 중량비로 1대 2내지 3이 바람직하며 사용되는 폴리우레탄폼의 두께는 3∼12㎜, ㎝당 눈금수는 8∼16개 정도 (20∼40 PPI : Pore Per Inch)가 바람직하다.On the other hand, since the adsorptivity of activated carbon is determined by the size and total surface area of the activated carbon, an adhesive which does not shield the pores should be selected when manufacturing an activated carbon filter, so that the polymer powder of the adhesive component is uniformly dispersed in the liquid and An adhesive in the form of an emulsion having a size larger than the pores of activated carbon is selected. In the present invention, an EVA (ethylene vinyl acetate) adhesive, which is an aqueous adhesive, is used. In addition, carboxy methyl cellulose (CMC) and / or polyvinyl alcohol (PVA) may be added to the adhesive as a preparation prior to mixing with activated carbon powder in order to prevent the fine particles of the emulsion solution from filling the pores and to provide flexibility of the manufactured filter. It is preferable to use mixed. When preparing an emulsion solution with activated carbon powder and adhesive, the mixing ratio thereof is preferably 1 to 2 to 3 by weight. The thickness of the polyurethane foam used is 3 to 12 mm and the number of scales per cm is about 8 to 16 ( 20-40 PPI: Pore Per Inch) is preferable.
이하 본 발명을 한정하지 아니하는 실시예에 의하여 본 발명의 활성탄공기 필터의 제조방법을 상세히 설명하면 다음과 같다.Hereinafter, the method for producing the activated carbon air filter according to the present invention will be described in detail with reference to the following Examples.
실시예1Example 1
수성계 접착제인 EVA계 접착제를 주제로 사용하였고 조제로 CMC(5% 이하 용액) 및 PVA(5%이하 용액)을 단독 또는 혼합 사용하여 주제 10의 비에 대하여 조제를 0∼10까지의 중량비로 혼합한 용액에 활성탄분말을 0∼20까지의 중량비로 혼합한 에멀젼용액을 제조하였다. 다음, 상기 에멀젼 용액에 폴리우레탄폼을 함침하고 압착롤러를 이용하여 압착도포하였는데 이때 압착롤러의 간극은 도포량을 결정하는 중요한 인자이기 때문에 폼의 규격 및 제품의 용도에 따라 탄력적으로 설정하였다. 1차 압착도포된 활성탄 필터에 활성탄 분말을 2차 압착도포시켰는데 이 공정을 거쳐 제조된 제품들은 적용시 제품에서 부분적인 활성탄의 탈리가 있을 수 있기 때문에 본 공정은 생략가능하며 활성탄 분말도포대신 에멀젼용액을 재도포할 수도 있다. 한편 활성탄의 흡착성능을 높게 유지하기 위하여 분말도포 또는 압착도포의 횟수는 제품의 용도에 따라 탄력적으로 결정하였다. 다음, 함침 및 도포를 거쳐 제조된 활성탄 공기필터를 50∼80℃에서 10분이상 체류시켜 건조부에서 건조시켰다.EVA-based adhesive, which is an aqueous-based adhesive, was used as the main agent, and the preparation was carried out in a weight ratio of 0 to 10 with respect to the ratio of main 10 by using CMC (5% or less solution) and PVA (5% or less solution) alone or in combination. An emulsion solution was prepared in which the activated carbon powder was mixed with the mixed solution in a weight ratio of 0 to 20. Next, the emulsion solution was impregnated with polyurethane foam and pressed using a pressing roller. At this time, the gap of the pressing roller was elastically set according to the size of the foam and the purpose of the product because it is an important factor for determining the coating amount. Activated carbon powder was applied to the primary compressed carbon filter by the second compression coating. Products manufactured through this process may be partially desorbed from the product when applied, so this process can be omitted and emulsion instead of powdered activated carbon. The solution may also be reapplied. On the other hand, in order to maintain a high adsorption performance of activated carbon, the number of powder coating or compression coating was elastically determined according to the use of the product. Next, the activated carbon air filter prepared by impregnation and application was dried at 50 to 80 ° C. for at least 10 minutes, and dried in a drying unit.
상기 실시예에 따라 제조된 활성탄 공기 필터의 흡착력, 부착력 및 탈착시험을 수행한바 그 결과는 아래와 같다.Adsorption, adhesion and desorption tests of the activated carbon air filter prepared according to the embodiment was carried out as follows.
본 발명은 실시예 1에 따라 제조된 활성탄 필터의 흡착력은 활성탄 공업분석에 관한 한국공업표준규격 (KSM-1802)의 요오드 흡착능 분석을 기준으로 하였다. 활성탄의 부착전 요오드흡착력은 1089㎎/gAC인 반면 부착활성탄의 요오드흡착력은 900㎎/gAC으로 확인되어 부착전에 비해 흡착력이 9%만이 감소되었음을 알 수 있었으며 본 발명의 접착제에 의한 세공차폐현상은 극히 적음을 알 수 있다.In the present invention, the adsorption power of the activated carbon filter prepared according to Example 1 was based on the iodine adsorption capacity analysis of the Korean Industrial Standards (KSM-1802). The iodine adsorption capacity of the activated carbon was 1089 mg / gAC, while the iodine adsorption capacity of the activated carbon was confirmed to be 900 mg / gAC, indicating that only 9% of the adsorption power was reduced compared to before the adhesion of the activated carbon. It can be seen that less.
한편, 본 발명의 활성탄 필터의 부착력은 무게 감량법을 사용하여 측정하였는데 제조된 활성탄 필터를 1㎠의 크기로 절단하여 10g을 취하고 이를 쇠구슬 10개와 함께 0.0063㎝의 체사이에 놓고 30분간 진탕한 후 진탕전후의 무게차를 측정하였다. 무게감량은 2%이하로서 본 발명에 따라 제조된 활성탄 공기필터의 부착력은 매우 우수함을 알 수 있었다.On the other hand, the adhesion of the activated carbon filter of the present invention was measured using a weight loss method, and the produced activated carbon filter was cut to a size of 1 cm 2, taking 10 g, which was placed in a sieve of 0.0063 cm with 10 iron beads and shaken for 30 minutes. The weight difference before and after shaking was measured. Weight loss is less than 2%, it was found that the adhesion of the activated carbon air filter prepared according to the present invention is very excellent.
또한 냄새를 유발하는 중요 가스에 대한 기상 홉탈착실험을 가스크로마토그래피를 사용하여 분석한 결과 흡착된 성분의 탈착은 흡착시 유속에서 홉착시간의 두배정도 소요되었으며, 이때 흡착량의 90%이상이 탈착됨이 확인되었다. 또한 80℃의 가열처리로 짧은 시간에 탈착이 가능하므로 매우 경제적으로 재생처리할 수 있는 장점 또한 본 발명에 따라 제조된 활성탄 필터는 지니고 있다.In addition, as a result of analyzing gas phase hop desorption experiment on the gas that causes odors, the adsorption of adsorbed components took about twice as much time as the time of adsorption at adsorption, and at least 90% of the adsorption amount was desorption. It was confirmed. In addition, since the desorption can be performed in a short time by heating at 80 ° C., the activated carbon filter manufactured according to the present invention also has the advantage of being economically regenerated.
