Description

은을 함유하는 합성수지제 관{Plastic Pipe Containing Ag}Silver-containing synthetic resin pipe {Plastic Pipe Containing Ag}

본 발명은 은을 함유하는 합성수지제 관에 관한 것이며, 특히 피브이씨(PVC)와 나노입도의 은(Ag) 분말을 혼합하고 이를 압출성형하여 제조된 은을 함유하는 피브이씨(PVC) 관으로서, 이 때 혼합되는 나노입도의 은 분말은 그 크기가 약 5～500 nm 이고, 제조되는 파이프 원료의 전중량에 대하여 혼합되는 은 분말의 중량비는 30 내지 500ppm 이며, 바람직하게는 100 내지 150ppm의 중량비를 갖도록 하여 혼합함으로써 항균성이 우수한 은을 함유하는 합성수지제 관을 제공한다.The present invention relates to a synthetic resin tube containing silver, and in particular, a fibrous (PVC) tube containing silver manufactured by mixing and extruding the fibrous (PVC) and nanoparticles of silver (Ag) powder. In this case, the nano-particles of the silver powder to be mixed is about 5 to 500 nm in size, the weight ratio of the silver powder to be mixed with respect to the total weight of the pipe raw material to be produced is 30 to 500ppm, preferably 100 to 150ppm By mixing in a weight ratio, a synthetic resin tube containing silver having excellent antibacterial properties is provided.

금속제관과 함께 상수관이나 배수관으로서 주로 사용되고 있는 합성수지제 수도관으로서 폴리염화비닐(Poly Vinyl Chloride, 피브이씨(PVC))관은 부식에 강하고, 녹이 슬지 않을 뿐 아니라, 중량이 크지 않아 취급 및 운반이 용이하며, 제조단가가 저렴하여 합성수지제 수도관으로서 주로 채택되어 제조, 사용되고 있다.Polyvinyl chloride (PVC) pipe is a synthetic resin water pipe that is mainly used as a water pipe or drainage pipe along with metal pipes. It is easy to use, and the manufacturing cost is low, so it is mainly adopted as a synthetic resin water pipe and manufactured and used.

그러나, 피브이씨(PVC)관은 그 사용이 장기화됨에 따라 관의 내벽에 얇은 층의 점성의 침전물이 생성되며, 상기 침전물은 완벽하게 정수되지 않은 상수 내부에 함유된 염류 등 이물질 성분이 관과 유수(流水)와의 마찰에 의한 정전기적 인력에 의해 관벽에 침착되면서 형성된 것으로, 상기 침전물층은 인체에 유해한 미생물 또 는 세균들이 번식할 수 있는 환경을 제공하는 역할을 한다. 따라서, 이러한 피브이씨(PVC)관을 통하여 공급되는 상수는 음용 기타 생활용수로의 사용에 부적합하다는 의구심을 발생시킬 수 있으며, 산업의 발전과 공해의 문제가 심각해지는 요즈음 이러한 의구심은 현실화되고 있거나, 현실화될 가능성이 매우 높아지고 있는 실정이다.However, as the PVC tube is prolonged in use, a thin layer of viscous precipitate is formed on the inner wall of the tube, and the precipitate has a foreign substance such as salts contained in a constant that is not completely purified. It is formed while being deposited on the wall of the pipe by electrostatic attraction due to friction with running water, and the sediment layer serves to provide an environment in which microorganisms or bacteria harmful to the human body can breed. Therefore, the constant water supplied through the PVC pipe may raise doubts that it is unsuitable for the use of drinking water and other living water, and these doubts are being realized these days when the problems of industrial development and pollution become serious. The possibility of becoming a reality is very high.

또한, 완벽하게 정수되지 않은 상수는 그 자체로서도 인체에 유해한 세균, 중금속 등이 포함되어 있어 이를 안심하고 음용하거나, 생활용수로 사용하기에 부적합하다는 문제점이 있었다.In addition, the constant that is not completely purified by itself contains bacteria, heavy metals and the like harmful to the human body there is a problem that it is not suitable for drinking or drinking water in peace.

한편, 은(Ag)은 항균성을 가진 재료로서 최근들어 주목을 받고 있는데, 이러한 은(Ag)은 인체에 무해하며, 균들의 은에 대한 내성이 발생되지 않고, 항균 지속기간도 거의 반영구적이므로 그 사용영역이 확대되고 있다. 그러나, 이러한 항균제로서의 효능을 갖는 은을 상수관 등의 제조단계에서 포함하여 제조, 사용한 예는 현재 전무한 실정이다.On the other hand, silver (Ag) has been attracting attention recently as a material having antimicrobial properties, such silver (Ag) is harmless to the human body, the resistance of the bacteria to the silver does not occur, and the antimicrobial duration is almost semi-permanent, its use The area is expanding. However, there are currently no examples of producing and using silver having such efficacy as an antimicrobial agent in manufacturing steps such as water pipes.

상술한 문제점들을 해결하기 위하여 본 발명은 합성수지제 관 중 특히 피브이씨(PVC)관의 원재료에 나노입도를 갖는 나노은 분말을 혼합하여 압출성형방법에 의해 은을 함유하는 합성수지제 관을 제조함으로써 상기 피브이씨(PVC) 관이 항균성을 갖도록 하여, 상기 피브이씨(PVC) 관을 상수관으로 사용하는 경우에도 상수를 일반인들이 음용하거나 생활용수로 사용하는데 적합하도록 하고자 하는데 목적이 있다. In order to solve the above problems, the present invention is to produce a synthetic resin tube containing silver by the extrusion molding method by mixing the nano-silver powder having a nano-particles in the raw material of the PVC tube, especially the PVC tube (PVC) The purpose of the PVC tube to have an antimicrobial, so that even when using the PVC tube as a constant pipe is intended to be suitable for drinking or drinking water for ordinary people.                         

또한, 상기 피브이씨(PVC) 관의 제조에 나노입도를 갖는 나노은 분말을 적용하여 동일한 중량의 조립(造立) 은(Ag) 분말에 비하여 비표면적을 향상시킴으로써 피브이씨(PVC) 관의 항균효과를 높이도록 하는데 또 다른 목적이 있다.In addition, by applying a nano silver powder having a nanoparticle size to the production of the PVC tube (PVC) by improving the specific surface area compared to the granulated silver (Ag) powder of the same weight antibacterial of the PVC tube (PVC) There is another purpose to increase the effect.

이하, 본 발명을 다음과 같은 실시례를 들어 좀 더 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the following examples.

본 발명은 합성수지제 관, 특히 피브이씨(PVC) 재질의 관을 제조하기 위한 원료물질들인 피브이씨(PVC)와 열안정제, 가공조제, 자외선 방지제, 충격보강재, 활제 등에 5～500nm의 입도를 갖는 나노은 30～500 ppm을 첨가하고 상기 혼합된 합성수지제 관 원료들을 교반용 날개를 구비하는 혼합기에서 균일하게 혼합한다. 여기서, 바람직하게는 상기 나노은은 100～150ppm을 첨가하여 혼합한다. 후술하는 바와 같이, 상기 첨가되는 나노은의 함량이 30 ppm 이하일 경우, 특정 균주에 대하여서는 상기 관의 항균력이 저하되며, 500 ppm 이상의 경우에는 500 ppm을 첨가한 경우와 거의 동일한 효과를 나타내므로 상기 나노은의 첨가량은 그 자체로 중요한 의미를 갖는다고 하겠다.The present invention is a particle size of 5 ~ 500nm to synthetic resin pipes, especially raw materials for the production of PVC pipes (PVC) and thermal stabilizers, processing aids, UV protection agents, impact reinforcing agents, lubricants, etc. Nano silver having 30 to 500 ppm is added and the mixed synthetic resin tube raw materials are uniformly mixed in a mixer having a stirring blade. Here, preferably, the nano silver is mixed by adding 100 to 150 ppm. As will be described later, when the content of the added nanosilver is 30 ppm or less, the antimicrobial activity of the tube is lowered for a specific strain, and when 500 ppm or more shows the same effect as when 500 ppm is added, the nanosilver The amount of added has an important meaning in itself.

상기 혼합된 원료들은 상기 혼합기 내에서 부유하며 입자간에 서로 마찰을 일으키게 되는데, 상기 마찰에 의하여 발생된 열로 인해 상기 원료들은 서로 융착한다.The mixed raw materials float in the mixer and cause friction between the particles, and the raw materials fuse with each other due to the heat generated by the friction.

다음에, 상기 혼합기의 전원을 차단하고, 혼합기 내의 온도를 약 50～70℃의 범위가 되도록 자연냉각(공냉)한다. 이 때, 상기 온도까지 냉각시키지 않는 경우에는 상기 원료의 흐름성이 부족하여 이송이 불가능하거나 어려우므로, 상기 냉각과 정은 반드시 필요하며, 냉각 후 압출성형 과정을 위하여 상기 원료들을 사일로로 이송한다.Next, the power supply of the mixer is cut off, and naturally cooled (air-cooled) so that the temperature in the mixer is in the range of about 50 to 70 ° C. In this case, if the temperature is not cooled to the temperature, the flowability of the raw material is insufficient, so that the transfer is impossible or difficult. Therefore, the cooling process is necessary, and the raw material is transferred to a silo for extrusion after cooling.

다음에, 상기 사일로에 저장되어 있던 원료는 압출기의 호퍼로 투입되고, 압출기는 170~210℃ 정도로 가열하면서 파이프를 압출성형하며, 이를 필요한 길이로 절단을 하고, 후가공을 함으로써 은을 함유하는 피브이씨(PVC)관을 제조하게 된다.Next, the raw material stored in the silo is introduced into the hopper of the extruder, and the extruder extrudes the pipe while heating it at about 170 to 210 ° C., cuts it to the required length, and post-processes the fib containing silver. The PVC tube will be manufactured.

상기와 같이 제조된 피브이씨(PVC) 관에는 5～500nm의 입도를 갖는 나노은 입자가 균일하게 분산되어 있어 상기 피브이씨(PVC)관은 전체적으로 우수한 항균성을 갖게 된다.The nanofibers having a particle size of 5 to 500 nm are uniformly dispersed in the fibrous (PVC) tube prepared as described above, so that the fibrous (PVC) tube has excellent antimicrobial activity as a whole.

상기 합성수지제 관은 상기와 같은 피브이씨(PVC) 재질의 관으로만 한정되는 것은 아니며, 그 외에도 피이(PE), 폴리스티렌, 폴리에스터, 폴리프로필렌, 폴리카보네이트 등으로 제조될 수 있다.The synthetic resin tube is not limited to the tube of the PVC material as described above, in addition, it may be made of PE (poly), polystyrene, polyester, polypropylene, polycarbonate and the like.

다음은 각 종류의 균주에 대하여 나노은으로 항균처리된 관 내부에서의 그 농도변화를 측정하여 나타낸 결과이다.The following is the result of measuring the change in concentration in the tube antimicrobial treatment with nano silver for each type of strain.

표 1 및 표 3의 결과로부터 알 수 있는 바와 같이 균주 1 및 3은 50ppm의 나노은을 첨가한 경우에 있어서 접종균의 감소율이 99.9％를 나타내었으며, 균주 2의 경우에도 나노은 100ppm 이상의 농도에서 접종균의 감소율이 99.9％에 이르는 것을 알 수 있다.As can be seen from the results of Tables 1 and 3, strains 1 and 3 showed a 99.9% reduction in inoculation bacteria when 50 ppm of nanosilver was added. It can be seen that the reduction ratio of 99.9%.
