Description

항균기능을 가지는 은나노 복합금속 제조방법{Manufacturing of nano silver composite metal containing anti bacterial effect}Manufacturing method of nano silver composite metal containing antibacterial effect

항균성 미세 복합금속입자의 활용기술에서 입자의 크기가 미세단위로 작게되면 입자의 물성 및 성능이 입자크기가 마이크로이상인 경우와는 매우 다르게된다. 이는 입자의 표면 대 질량의 비율이 증가되어 단위 질량당 표면적이 증가되어 입자의 성능이 향상되고 입자의 융점이 감소되는 등 물성이 변화되며 입자의 생상까지 크기에 따라 변화되는 등 큰 입자의 경우와는 다른 성질은 나타낸다When the particle size is reduced to a fine unit in the application technology of the antimicrobial fine composite metal particles, the physical properties and performance of the particles are very different from those of the micro size or more. This is due to the increase in the surface-to-mass ratio of the particles, which increases the surface area per unit mass, which improves the performance of the particles, decreases the melting point of the particles, and changes the physical properties and changes depending on the size of the particles. Other properties indicate

크기 분포가 균일한 미세 복합금속 입자를 경제적이고 간단한 공정으로 대량생산하는 것을 이루고자한다.To achieve mass production of fine composite metal particles with uniform size distribution in an economical and simple process.

기존의 미세한 복합금속입자 제조기술은 대량생산과 원가면에서 매우 불리하나 본 발명은 미세 복합금속입자 제조공정이 간단하고 형성되는 입자의 크기도 계면활성제의 종류,농도,작업온도,수용액의 조건등의 간단한 변화로 쉽게 조절한다.Conventional fine metal composite particle manufacturing technology is very disadvantageous in terms of mass production and cost, but the present invention is a simple process for producing a fine metal composite particle and the size of the particles formed, the type of surfactant, concentration, working temperature, aqueous solution, etc. Easily adjusted with a simple change of.

본 발명에서는 항균성 은 세라믹복합 나노입자를 제조하기 위해서 수상 합성 방법을 사용하였다.In the present invention, an aqueous phase synthesis method was used to prepare the antimicrobial silver ceramic composite nanoparticles.

수상합성 방법은 저온에서 가능하도옥 하기위하여 두가지 이상의 염이 용해된 용액을 저어주면서 서서히 첨가하면 계면활성제의 종류와 농도에 따라 크기 및 크기 분포가 다른 미세 복합금속 입자가 제조된다.In the water phase synthesis method, in order to be possible at a low temperature, when a solution of two or more salts is stirred and added slowly, fine composite metal particles having different sizes and size distributions are prepared according to the type and concentration of the surfactant.

여기서 첨가될 수 있는 계면활성제는 비이온성,음이온서,양이온성,양쪽성탄놔수소계,등 모든 종류의 계면활성제가 사용된다.Surfactants that can be added here include all kinds of surfactants such as nonionic, anionic, cationic, amphiphilic, hydrogen-based, and the like.

본 발명의 효과로는In the effect of the present invention

-입자의 구성이 두 가지 이상의 성분으로 구성되어 있으므로 한 입자가 두 가지 이상의 금속 성분의 복합특성을 갖고-Since the particle is composed of two or more components, one particle has a complex characteristic of two or more metal components.

-다양한 미세 복합금속 입자를 경제적이고 간단한 제조공정으로 대량생산이 용이하고 -It is easy to mass-produce various fine composite metal particles with economical and simple manufacturing process

-형성되는 입자의 크기가 미세하며 (300nm 이하) 크기분포가 균일하여 입자의 성능이 우수하고-The particle size is fine (300nm or less) and the size distribution is uniform, so the particle performance is excellent.

-입자의 크기가 적으므로 고분자 필름에 분산시 필름의 외형이 투명 또는 반 투명 상태를 유지하고-Since the particle size is small, the appearance of the film remains transparent or semi-transparent when dispersed in the polymer film.

-복합금속 입자의 산화방지를 위하여 항산화제와 함께 이용함으로 미세 복합금속 입자의 성능을 장시간 유지할 수 있다.
-Can be used together with antioxidants to prevent oxidation of composite metal particles to maintain the performance of fine composite metal particles for a long time.
