이하, 첨부한 도면을 참조하여 본 발명에 의한 조성물의 성형 및 이를 이용한 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the molding of the composition according to the present invention and preferred embodiments using the same.
먼저, 제1실시예로 도 1 의 (나)(다)에 도시된 바와같이 전자파흡수체와 전도성물질을 고무에 혼합하여 자기장 흡수, 전기장 차단 및 항균 조성물을 제조하였다. 제조된 조성물은 압축성형을 통하여 다양한 형태의 제품으로 제조되며, 도 1 의 (가)에는 이와같은 방법으로 제조된 조성물이 적용된 자동차 바닥용 고무매트(1)를 나타내고 있다.First, as a first embodiment, as shown in FIG. 1B, the electromagnetic wave absorber and the conductive material were mixed with rubber to prepare a magnetic field absorbing, electric field blocking, and antimicrobial composition. The prepared composition is made into various types of products through compression molding, and Fig. 1 (a) shows a rubber mat (1) for automobile floors to which the composition prepared in this manner is applied.
제2실시예로는 도 2 에 도시된 바와같이 전자파흡수체와 전도성물질을 열가소성수지와 혼합하여 압출기를 통하여 펠렛트화한 조성물수지(5)를 제조하거나, 전자파흡수체와 전도성물질이 각각 첨가된 수지에 대하여 펠렛트화된 수지(5)를 제조하게 된다. 이들을 이용하여 상기 제1실시예에서와 같은 방법으로 자기장만 흡수하거나 전기장만 차단하는 항균기능이 발휘되는 단층의 매트를 제조하게 된다.In the second embodiment, as shown in FIG. 2, a composition resin 5 is prepared by mixing an electromagnetic wave absorber and a conductive material with a thermoplastic resin and pelletized through an extruder, or in the resin to which the electromagnetic wave absorber and the conductive material are added, respectively. The pelletized resin 5 is prepared. Using these, a single-layered mat having an antimicrobial function that absorbs only a magnetic field or blocks only an electric field is produced in the same manner as in the first embodiment.
그리고 제3실시예로는 도 3 의 (가)에 도시된 바와같이 라미네이팅법을 이용하여 자기장 흡수 및 항균기능이 부가된 전자파흡수체층(2)과 전기장 차단기능의 전도성물질층(3)의 2층구조로 제품을 제조하거나, (나)에 도시된 바와같이 전도성물질층(3)의 상/하에 각각 전자파흡수체층(2)을 형성한 3층구조로 제품을 제조하여 전자파흡수체층(2)이 전도성물질층(3)을 외부로부터 절연시키는 역할을 이루도록 하였다.In the third embodiment, as shown in (a) of FIG. 3, the electromagnetic wave absorber layer 2 and the conductive material layer 3 having the electric field blocking function added to the magnetic field absorbing and antimicrobial functions using the laminating method. The product is manufactured in a layer structure, or the product is manufactured in a three-layer structure in which the electromagnetic wave absorber layer 2 is formed on and under the conductive material layer 3, as shown in (b). The conductive material layer 3 is to be insulated from the outside.
이를 통하여 층간 상이한 성능인 자기장 흡수 및 항균기능과 전기장 차단기능으로 나뉘어진 상태에서, 일층에서 자기장이 완전히 흡수되지 않아 통과하게 되면 타층에서 전기장을 차단함으로써 전자파 및 각종 균에 대하여 차단하는 효과를 낼 수 있는 것이다.Through this, the magnetic field absorption and antibacterial function and the electric field blocking function, which are different performances between layers, can be prevented against electromagnetic waves and various germs by blocking the electric field in the other layer when the magnetic field is not completely absorbed. It is.
도 4 은 본 발명의 제4실시예로 나타낸 것으로서, (가)는 단층으로 이루어지는 전자파 흡수, 차단 및 항균기능 매트(1)의 어두운색을 보완하고 외관을 미려하게 하기 위하여, 상/하층에 각각 인쇄층(10)과 백층(20)을 부착시킨 것이고,Figure 4 is shown as a fourth embodiment of the present invention, (A) to complement the dark color of the electromagnetic wave absorbing, blocking and antimicrobial function mat (1) consisting of a single layer, each in the upper and lower layers, The printed layer 10 and the back layer 20 are attached,
(나)와 (다)는 각각 인쇄층(10) 및 백층(20)을 도 2 에 도시된 2층 및 3층구조에 적용한 실시예를 나타내고 있다.(B) and (c) show an example in which the print layer 10 and the back layer 20 are applied to the two-layer and three-layer structures shown in FIG.
한편, 비교예로서 하기 [표 1]에는 특정 주파수에서의 상기 각 조성에 따른 매트에서의 전자파 차폐율 측정결과를 나타낸 것으로 측정매트의 두께는 1.5mm이다.On the other hand, as a comparative example, Table 1 below shows the result of measuring the electromagnetic shielding rate in the mat according to each composition at a specific frequency, the thickness of the measuring mat is 1.5mm.
[표 1] (단위 : -dB)[Table 1] (Unit: -dB)
상기 [표 1]에서 보면 전자파흡수체와 전도성물질이 층별로 라미네이트된 매트가 측정하는 10MHz∼5GHz대역의 주파수 범위에서 전자파 차폐효과가 가장 우수하게 나타났으며, 특히 도 3 의 (나)와 같은 3층구조의 라미네이트 매트의 경우 외부에 드러나는 전도성물질층(3)이 전기에 대하여 절연성을 나타내어 안전면에서 가장 우수한 성능을 나타냄을 알 수 있었다.In Table 1, the electromagnetic wave shielding effect was most excellent in the frequency range of the 10MHz to 5GHz band measured by the mat laminated by the electromagnetic wave absorber and the conductive material, in particular, as shown in (b) of FIG. In the case of the laminated mat of the layer structure, the conductive material layer 3 exposed to the outside was insulated against electricity, and thus it was found that it showed the best performance in terms of safety.
또한 매트의 두께를 2,3,4,5mm로 두껍게 할수록 전자파 차폐효과가 우수하게 나타났으며, 본 발명에 의한 제품은 전자파를 차단만 하는 것이 아니고 흡수도 하면서 전자파를 제거하므로 환경의 무전자파화를 이룰 수 있게 된다.In addition, the thicker the thickness of the mat to 2, 3, 4, 5mm, the better the electromagnetic shielding effect, the product according to the present invention does not only block the electromagnetic wave but also absorbs the electromagnetic wave to remove the electromagnetic wave of the environment Can be achieved.
그리고 조성물의 항균실험을 위하여 합성고무에 전자파흡수체 15중량%와 전도성물질 20중량%를 혼합하여 제작된 제품과, 전도성물질 40중량%로만 되어진 제품, 그리고 전자파흡수체 30중량%로만 첨가된 제품을 각각 따로 준비하여 항균시험을 실시하였으며, [표 2]에 그 결과를 나타내었다.And for the antimicrobial test of the composition, a product made by mixing 15% by weight of the electromagnetic wave absorber and 20% by weight of the conductive material in the synthetic rubber, a product made of only 40% by weight of the conductive material, and a product added only with 30% by weight of the electromagnetic wave absorber, respectively. Separately prepared and carried out an antibacterial test, the results are shown in [Table 2].
시험결과에 의하면 본 발명이 적용된 시편은 세균에 대하여 항균효과가 있음을 확인할 수 있었으며, 적용된 실험외에 내성황색포도균, 녹농균등에서도 유사한 항균효과를 나타내었다. 첨가되는 전도성물질보다 전자파흡수체가 균 억제효과는 뛰어났고, 어디에도 언급된 바 없는 전도성물질에서도 항균효과가 있음을 입증한 결과임을 알 수 있다.According to the test results, it was confirmed that the specimen to which the present invention was applied had an antimicrobial effect against bacteria, and showed similar antimicrobial effects in resistant Staphylococcus aureus and Pseudomonas aeruginosa in addition to the applied experiment. It can be seen that the electromagnetic wave absorber was more excellent in inhibiting bacteria than the conductive material added, and the result proved that the conductive material had no antimicrobial effect.
본 실험에서 시편 표면적은 5㎠이고, 세균액을 25℃에서 24시간 진탕배양후, 균수 측정(진행회수 150회/분)을 하였으며, 측정방법은 섀이크플래스크(Shake Flask)방법, 대장균은 Escherichia Coli ATCC25922를 사용하였다.In this experiment, the surface area of the specimen was 5 cm2, and the bacterial solution was incubated at 25 ° C. for 24 hours, and then the number of bacteria was measured (150 times / minute). The measurement method was Shake Flask method and Escherichia coli. Escherichia Coli ATCC25922 was used.
[표 2]TABLE 2
또한, 제조된 시트의 곰팡이 억제효과를 알아보기 위하여 조성을 달리한 4종의 시트위에 수분이 함유된 식빵을 2주동안 두고 측정하였다. 측정방법은 식빵과 접촉한 시트면적 대비 곰팡이 발생면적을 측정하였으며, 이에 대한 측정결과는 [표 3]에 나타내었다.In addition, in order to determine the mildew inhibitory effect of the prepared sheet was measured for two weeks bread containing moisture on the four sheets of different compositions. The measurement method measured the area of mold generation compared to the sheet area in contact with the bread, the measurement results are shown in [Table 3].
[표 3]TABLE 3
또한, 하기 [표 4]는 전자파흡수체와 전도성물질별 첨가량의 변화에 따른 곰팡이 발생상태를 나타낸 것으로서, 결과에서 알 수 있듯이 전자파흡수체 또는 전도성물질의 첨가량이 증가할수록 뛰어난 곰팡이 억제효과가 나타남을 알 수 있었다.In addition, [Table 4] shows the mold generation state according to the change in the amount of addition of the electromagnetic wave absorber and the conductive material, as can be seen from the results as the increase in the amount of addition of the electromagnetic wave absorber or the conductive material showed excellent mold suppression effect there was.
[표 4]TABLE 4
이상에서 살펴본 실험결과에서 보면, 본 발명의 조성물 및 이를 응용한 제품에 사용된 전자파흡수체는 전자파중에서 자기장을 흡수하고, 전도성물질은 전기장을 차단하는 특성으로 인하여 전자파를 차폐하는 성능이 있음을 알 수 있다. 그리고 상기 전도성물질은 고주파대역에서는 전자파를 흡수하는 특성으로 인해 고주파대역에서 전자파 차폐능력이 매우 우수하게 나타났다. 그리고 전자파흡수체와 전도성물질의 함량을 증가시킬수록 차폐효과는 우수하였으나, 첨가량이 많아질수록 가공성이 떨어지며 취성현상이 나타났다.In the above experimental results, it can be seen that the electromagnetic wave absorber used in the composition of the present invention and the applied product absorbs the magnetic field in the electromagnetic wave, and the conductive material has the ability to shield the electromagnetic wave due to the property of blocking the electric field. have. In addition, the conductive material has excellent electromagnetic shielding ability in the high frequency band due to the characteristic of absorbing electromagnetic waves in the high frequency band. The shielding effect was excellent as the content of the electromagnetic wave absorber and the conductive material was increased. However, as the addition amount increased, the workability decreased and the brittleness appeared.
