이하, 본 발명에 따른 구리가 함유된 실리콘 고무 조성물을 상세히 설명하면 다음과 같다.Hereinafter, the copper-containing silicone rubber composition according to the present invention will be described in detail as follows.
본 발명에 따른 구리가 함유된 실리콘 고무 조성물은 본 발명은 실리콘 고무 조성물에 있어서, 실리콘 고무에 구리 분말이 혼합되어 이루어지는 것을 특징으로 한다.The silicone rubber composition containing copper according to the present invention is characterized in that in the silicone rubber composition, copper powder is mixed with the silicone rubber.
보다 구체적으로 보다 구체적으로 구리가 함유된 실리콘 고무 조성물은 실리콘 고무 100 중량부에 대하여, 입자크기 0.1 ~ 1mm의 구리 분말 1 ~ 50 중량부가 혼합되어 이루어진다.More specifically, the silicone rubber composition containing copper is made by mixing 1-50 parts by weight of copper powder having a particle size of 0.1 to 1 mm with respect to 100 parts by weight of the silicone rubber.
여기서 상기 구리 분말의 함량이 1 중량부 미만일 경우 항균 및 살균 기능이 미비해질 우려가 있으며, 50 중량부를 초과할 경우 실리콘 고무의 물성이 저하될 우려가 있다.Here, when the content of the copper powder is less than 1 part by weight, there is a fear that the antibacterial and sterilization functions are insufficient, and when it exceeds 50 parts by weight, there is a fear that the physical properties of the silicone rubber may be deteriorated.
또한 상기 구리 분말의 입자크기가 0.1mm 미만일 경우 항균 및 살균 기능이 미비해질 우려가 있으며, 1mm를 초과할 경우 실리콘 고무에 대한 분산성이 저하될 우려가 있다.In addition, when the particle size of the copper powder is less than 0.1mm, there is a fear that the antibacterial and sterilization functions are insufficient, and when it exceeds 1mm, there is a fear that the dispersibility to the silicone rubber is lowered.
한편, 상기 구리분말은 비닐메톡시 실란, 비닐트리메톡시 실란, 비닐에폭시 실란, 3-아미노프로필트리에톡시 실란, N-(β-아미노에틸)-γ-아미노프로필메틸디메톡시 실란 또는 N-(β-아미노에틸)-γ-아미노프로필메틸디메톡시 실란 등의 개질제를 이용하여 표면을 개질한 후 적용함으로써, 기재에 대한 분산성을 더욱 향상시킬 수 있다. On the other hand, the copper powder is vinylmethoxy silane, vinyltrimethoxy silane, vinylepoxy silane, 3-aminopropyltriethoxy silane, N-(β-aminoethyl)-γ-aminopropylmethyldimethoxy silane or N- By applying after modifying the surface using a modifier such as (β-aminoethyl)-γ-aminopropylmethyldimethoxy silane, the dispersibility to the substrate can be further improved.
보다 구체적으로 구리분말 100 중량부에 대하여 개질제 1 ~ 20 중량부를 혼합하여 표면개질하여 사용할 수 있으며, 개질제의 함량이 상기 범위를 벗어날 경우 분산성 향상 효율이 저하될 우려가 있다.More specifically, 1 to 20 parts by weight of a modifier may be mixed with respect to 100 parts by weight of the copper powder to be used for surface modification.
한편, 상기 개질방법은 구리분말에 개질제를 혼합하거나 또는 구리분말을 개질제에 함침하거나 또는 개질제를 분사하는 등 다양한 방법을 적용할 수 있다.On the other hand, as the reforming method, various methods such as mixing a modifier with copper powder, impregnating copper powder with a modifier, or spraying a modifier can be applied.
이하, 본 발명을 아래 실시예에 의거하여 더욱 상세히 설명하겠는바 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail based on the following examples, but the present invention is not limited by the examples.

Then, a sample was prepared by cutting the silicone rubber according to each of the Examples and Comparative Examples to 3 × 3 cm, and 0.2 ml of the bacterial inoculum was placed thereon and a PE film cut to 4 × 4 cm was covered thereon. After inoculation, the sample was placed in a glass plate to maintain humidity, and the bacteria were extracted after incubation at 37 °C for 24 hours. The sample taken out after a predetermined time was extracted using 2.4 ml of saline (including 0.005% Tween #80), and 1.0 ml of the extract and dilution solution were smeared on a plate medium. The inoculated medium was again incubated at 37 ° C, 24 After time, the number of bacteria was measured, and the results are shown in [Table 1] below.

상기 [표 1]에서와 같이 본 발명에 따른 본 발명에 따른 구리가 함유된 실리콘 고무 조성물은 항균 및 살균 기능이 우수함을 알 수 있다.상술한 바와 같이, 본 발명에 따른 구리가 함유된 실리콘 고무 조성물은 상기의 바람직한 실시 예를 통해 설명하고, 그 우수성을 확인하였지만 해당 기술 분야의 당업자라면 하기의 특허 청구 범위에 기재된 본 발명의 사상 및 영역으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경시킬 수 있음을 이해할 수 있을 것이다.As shown in Table 1 above, it can be seen that the copper-containing silicone rubber composition according to the present invention according to the present invention has excellent antibacterial and sterilizing functions. As described above, the copper-containing silicone rubber according to the present invention Although the composition has been described through the above preferred embodiments, and its excellence has been confirmed, those skilled in the art can variously modify and change the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below. You will understand that it can be done.
본 발명은 실리콘 고무에 구리 분말을 첨가하되, 구리 분말을 표면 개질하여 그 분산성을 향상시킴으로써 구리 분말에 의한 항균 및 살균 기능을 효율적으로 발현시킬 수 있도록 하고, 이로 인해 우수한 항균 및 살균 기능을 구현하는 효과가 있으므로, 산업상 널리 이용될 것으로 기대된다.In the present invention, copper powder is added to silicone rubber, but the copper powder is surface-modified to improve its dispersibility so that the antibacterial and sterilizing function by the copper powder can be efficiently expressed, thereby realizing the excellent antibacterial and sterilizing function. Therefore, it is expected to be widely used in industry.
