The binder polymer serves as a binder to stably connect and stably connect the ceramic mixed powder and the activated carbon powder, or the powder and the solid type activated carbon block in the porous surface coating solution. The binder polymer is preferably a polymer having a glass transition temperature (Tg) of -200 to 200 ° C, more specifically, polyvinylidene fluoride-hexafluoropropylene. ), Polyvinylidene fluoride-cotrichloroethylene, polymethylmethacrylate, polyacrylonitrile, polyvinylpyrrolidone, polyvinylacetate ( polyvinylacetate, polyethylene-co-vinyl acetate, polyethylene oxide, cellulose acetate, cellulose acetate butyrate, cellulose acetate propionate ), Cyanoethylpullulan lan, cyanoethylpolyvinylalcohol, cyanoethylcellulose, cyanoethylsucrose, pullulan, carboxyl methyl cellulose and mixtures thereof One or more kinds selected from the group can be used. More specifically, by using a mixture of polyvinylidene fluoride-cotrichloroethylene and cellulose acetate in a weight ratio of 2: 1, the above effects can be further exhibited.
상기 세라믹 혼합분말은 다공성 표면코팅층을 이루는 단단한 지지체 역할을 하는 것으로, 공기 정화용 활성탄 필터의 정화 효율을 고려하여, 바인더 고분자 100 중량부에 대하여, 세라믹 혼합분말 40 내지 100 중량부가 포함되는 것이 좋다. 이러한 세라믹 혼합분말은 세라믹을 포함한 무기물{α-, β-삼인산칼슘 (α-, β-TCP, α-, β-tri-calcium phosphate)}, 합성/천연 수산화아파타이트(HA), 칼슘메타포스페이트(CMP, Calcium metaphosphate)나 금속(알루미나) 분말 및 이들의 혼합물로 이루어진 군에서 선택되는 1종 이상인 것을 사용할 수 있다. The ceramic mixed powder serves as a rigid support forming the porous surface coating layer. In consideration of the purification efficiency of the activated carbon filter for air purification, the ceramic mixed powder may include 40 to 100 parts by weight of the ceramic mixed powder. These ceramic mixed powders are composed of inorganic materials including ceramics {α-, β-tricalcium phosphate (α-, β-TCP, α-, β-tri-calcium phosphate)}, synthetic / natural apatite hydroxide (HA), calcium metaphosphate ( CMP, Calcium metaphosphate) or metal (alumina) powders and mixtures thereof may be used at least one selected from the group consisting of.
또한, 상기 활성탄 분말은 공기 정화용 활성탄 필터의 정화 효율 및 다공성 표면코팅층의 기계적 강도를 고려하여, 바인더 고분자 100 중량부에 대하여, 활성탄 분말 10 내지 50 중량부가 포함되는 것이 좋다.In addition, the activated carbon powder may include 10 to 50 parts by weight of activated carbon powder based on 100 parts by weight of the binder polymer in consideration of the purification efficiency of the activated carbon filter for air purification and the mechanical strength of the porous surface coating layer.
상기 용매는 다공성 표면코팅용 용액의 균일한 혼합과 이후 용매 제거를 용이하게 하기 위하여, 끓는점(boiling point)이 낮은 것을 사용하는 것이 좋다. 이러한 용매를 예로 들면, 아세톤 (acetone), 테트라하이드로퓨란 (tetrahydrofuran), 메틸렌클로라이드 (methylene chloride), 클로로포름 (chloroform), 디메틸포름아미드 (dimethylformamide), N-메틸-2-피롤리돈 (N-methyl-2-pyrrolidone, NMP), 시클로헥산 (cyclohexane), 물 및 이들의 혼합물로 이루어진 군에서 선택되는 1종 이상인 것을 사용할 수 있다. 특히, 아세톤 (acetone), 테트라하이드로퓨란 (tetrahydrofuran), 및 물을 2: 2: 1의 중량비로 혼합한 것을 사용하는 것이 좋다.The solvent may be a low boiling point to facilitate uniform mixing of the solution for porous surface coating and subsequent solvent removal. Examples of such solvents include acetone, tetrahydrofuran, methylene chloride, chloroform, dimethylformamide, N-methyl-2-pyrrolidone (N-methyl 2-pyrrolidone, NMP), cyclohexane (cyclohexane), water and one or more selected from the group consisting of a mixture thereof may be used. In particular, it is preferable to use acetone, tetrahydrofuran, and water in a weight ratio of 2: 2: 1.
상기 다공성 표면코팅용 용액에서 상기한 성분들의 분산의 순서는 본 발명의 본질과는 관계없다. 그러나, 세라믹 혼합분말과 활성탄 분말입자가 균일하게 분산된 상태의 다공성 표면코팅용 용액을 얻기 위하여, 먼저 바인더 고분자를 용매에 용해시킨 다음, 별도의 용기에서 세라믹 혼합분말과 활성탄 분말입자를 각각 상기 용해액에 분산시킨 다음, 코팅 직전에 상기 세라믹 혼합분말 분산액 및 활성탄 분말입자 분산액을 혼합하여 코팅하는 것이 바람직하다.The order of dispersion of the above components in the porous surface coating solution is irrelevant to the nature of the present invention. However, in order to obtain a porous surface coating solution in which the ceramic mixed powder and the activated carbon powder particles are uniformly dispersed, the binder polymer is first dissolved in a solvent, and then the ceramic mixed powder and the activated carbon powder particles are respectively dissolved in a separate container. After dispersing in a liquid, it is preferable to mix and coat the ceramic powder mixture dispersion and activated carbon powder particle dispersion immediately before coating.
상기 준비된 고형타입 활성탄 블록의 표면을 다공성 코팅하는 단계에서, 상기 코팅은 다공성 표면코팅용 용액을 스프레이 코팅한 것 또는 다공성 표면코팅용 용액을 침지용액으로 하여, 여기에 상기 준비된 고형타입 활성탄 블록을 침지시킴으로써 고형타입 활성탄 블록의 표면을 코팅한 것일 수 있다. 이로써, 고형타입 활성탄 블록의 표면에 50 내지 500 μm의 얇은 두께의 다공성 표면코팅층을 용이하게 형성시켜, 활성탄에서 미분진이 발생하는 것을 원천적으로 차단하면서도, 정화 효율 및 필터 수명을 유지할 수 있는 효과가 있는 것이다. 따라서, 상기 다공성 표면코팅층의 두께가 너무 얇으면, 활성탄에서 미분진이 발생하는 것을 원천적으로 차단할 수 없는 단점이 있고, 너무 두꺼운 경우에는 정화 효율을 유지하거나, 이로 인한 필터 수명에 문제가 발생할 수 있으므로 상기한 두께를 유지하는 것이 바람직하다. In the porous coating of the surface of the prepared solid type activated carbon block, the coating is spray coated with a porous surface coating solution or a porous surface coating solution as an immersion solution, and the prepared solid type activated carbon block is immersed therein. By doing so, the surface of the solid type activated carbon block may be coated. As a result, a porous surface coating layer having a thin thickness of 50 to 500 μm is easily formed on the surface of the solid type activated carbon block, thereby preventing the generation of fine dust in the activated carbon, while maintaining the purification efficiency and filter life. will be. Therefore, if the thickness of the porous surface coating layer is too thin, there is a disadvantage that can not block the generation of fine dust in the activated carbon, and if too thick to maintain the purification efficiency, or may cause problems in the filter life due to this It is desirable to maintain one thickness.
상기 열처리는 600 내지 1200 ℃로 분당 0.01 내지 5 ℃로 승온하여 수행함으로써, 바인더 고분자 및 용매는 탄화 및 휘발시키고, 세라믹 혼합분말과 활성탄 분말입자가 보다 더 치밀하게 연결됨으로써, 요구하는 강도를 얻게 되고, 구조적으로 10 내지 200 ㎛의 미세기공과 200 내지 1000 ㎛의 거대기공이 서로 연결되어 있는 다공성 표면코팅층을 얻을 수 있는 것이다. The heat treatment is performed by heating to 600 to 1200 ℃ at 0.01 to 5 ℃ per minute, the binder polymer and the solvent is carbonized and volatilized, and the ceramic mixed powder and the activated carbon powder particles are more closely connected, thereby obtaining the required strength To obtain a porous surface coating layer in which micropores of 10 to 200 μm and macropores of 200 to 1000 μm are connected to each other structurally.
