(6) 전자파 차폐 특성(6) electromagnetic wave shielding properties

제조예 1, 제조예 2, 비교제조예 1 및 비교제조예 2에서 제조한 휴대폰 케이스를 시편 규격으로 가공하고 전자파 차폐 효과를 ASTM D4935-89 테스트 방법으로 측정하였다. 전자파 차폐율은 전자파 차폐 효과를 측정한 후 환산하여 얻었다.The mobile phone cases prepared in Preparation Example 1, Preparation Example 2, Comparative Preparation Example 1, and Comparative Preparation Example 2 were processed into specimen standards, and the electromagnetic wave shielding effect was measured by the ASTM D4935-89 test method. The electromagnetic shielding rate was obtained by measuring the electromagnetic shielding effect and converting it.

전자파 차폐 효과는 입사 전력에 대해 시편을 통과하여 수신되는 수신 전력의 비로서 정의된다. 시편 재료를 통과해 수신되는 전력을 P1이라 하고 재료가 없는 상태에서의 수신 전력을 P2라 하면 재료의 전자파 차폐 효과(dB)는 아래 식으로 계산된다.The electromagnetic shielding effect is defined as the ratio of the received power received through the specimen to the incident power. If the power received through the specimen material is P1 and the received power in the absence of material is P2, the electromagnetic shielding effect (dB) of the material is calculated by the following equation.

dB = 10 × logP1/P2dB = 10 × logP1/P2

측정방법은 ASTM(D4935-89) 규격의 플랜지형 동축 전송선 측정 치구(flanged circular coaxial transmission line sample holder)를 사용하였다. 이 측정 기구는 원역장의 전자파 차폐효과를 측정하는데 사용되며, 측정 신뢰도가 높고 반복적인 실험 결과를 얻을 수 있어 재료의 원역장 차폐 특성을 측정하는 기준 측정 기구로 사용할수 있다. 두 개의 큰 동축형 플렌지 사이에 디스크형의 시편을 넣고 전자파를 입사시키면 두 값의 차로부터 시편 재료의 전자파 차폐 효과를 구할 수 있다. 이 측정 기구를 사용할 때의 측정 주파수 대역은 1MHz ~ 18GHz 정도인데 주파수 하한은 측정 기기의 주파수 한계에 의해 제한되며, 주파수 상한은 치구의 물리적 크기에 의한 공진 주파수에 의해 제한된다. 측정된 전자파 차폐 효과가 "-A(dB)" 값을 가지는 경우, 전자파 차폐율(%)은 (1-10-A/10)×100의 식으로 얻어진다.As a measurement method, a flanged circular coaxial transmission line sample holder of ASTM (D4935-89) standard was used. This measuring instrument is used to measure the electromagnetic wave shielding effect of the far field, and it can be used as a reference measuring instrument to measure the far field shielding properties of a material because it has high measurement reliability and can obtain repetitive test results. When a disk-shaped specimen is inserted between two large coaxial flanges and electromagnetic waves are incident, the electromagnetic shielding effect of the specimen material can be obtained from the difference between the two values. When using this measuring device, the measurement frequency band is about 1MHz ~ 18GHz, the lower limit of the frequency is limited by the frequency limit of the measuring device, and the upper limit of the frequency is limited by the resonant frequency due to the physical size of the fixture. When the measured electromagnetic shielding effect has a value of "-A(dB)", the electromagnetic shielding rate (%) is obtained by the formula of (1-10 -A /10) x 100.

제조예 1, 제조예 2, 비교제조예 1 및 비교제조예 2에서 제조한 휴대폰 케이스를 원형으로 잘라 시험 시편을 준비하였다. 이후, 오염포(TEST FABRICS社의 STC EMPA 106)를 Universal Wear Tester에 끼우고, 시험 시편을 바닥에 고정시켰다. 이후, 0.9 ㎏f 하중의 추를 위에서 가하고 압력을 2psi로 맞춘 후 헤드를 낮추어 오염포를 시험 시편에 접촉시키고 오염포를 앞뒤로 움직이도록 500회 작동시켰다. 이후, 오염포를 교체하고 추가적으로 500회 작동시켰다. 이후, 색차계로 시험 시편의 비오염부위와 오염부위의 반사값을 측정하고, 오염성을 아래와 같은 수식으로 계산하였다. 오염성 값이 낮을 수록 내오염성이 우수한 것으로 볼 수 있다.The cell phone cases prepared in Preparation Example 1, Preparation Example 2, Comparative Preparation Example 1, and Comparative Preparation Example 2 were cut into circles to prepare test specimens. Thereafter, the contamination cloth (STC EMPA 106 of TEST FABRICS) was inserted into the Universal Wear Tester, and the test specimen was fixed to the floor. Thereafter, a weight of 0.9 kgf was applied from the top, the pressure was adjusted to 2psi, and the head was lowered to bring the soiled cloth into contact with the test specimen and operated 500 times to move the soiled cloth back and forth. Thereafter, the dirty cloth was replaced and an additional 500 times were operated. Thereafter, the reflection values of the non-contaminated area and the contaminated area of the test specimen were measured with a color difference meter, and the contamination property was calculated by the following equation. It can be seen that the lower the contamination resistance value, the better the contamination resistance.

오염성(%) = (R0- R1)×100/R0Pollution (%) = (R0- R1)×100/R0

* R0 : 초기 반사율* R0: Initial reflectance

* R1 : 오염 후 반사율* R1: Reflectance after contamination
