전자파 차폐 필름
롤 보관 시에 블로킹이 생기기 어렵고, 내습성 및 내굴곡성이 우수한 전자파 차폐 필름을 제공한다. 본 발명의 전자파 차폐 필름은 보호층과, 차폐층이 적층된 전자파 차폐 필름으로서, 상기 보호층은, 산가가 2000∼4000g/eq, 또한, Tg가 0℃ 이상인 우레탄계 수지와, 평균 입자 직경이 10㎛ 이하인 비도전성 필러를 포함하고, 상기 보호층의 전체 중량에 대한 상기 비도전성 필러의 중량 비율은 10∼40 중량%인 것을 특징으로 한다. Provided is an electromagnetic wave shield film which...

| description | 롤 보관 시에 블로킹이 생기기 어렵고, 내습성 및 내굴곡성이 우수한 전자파 차폐 필름을 제공한다. 본 발명의 전자파 차폐 필름은 보호층과, 차폐층이 적층된 전자파 차폐 필름으로서, 상기 보호층은, 산가가 2000∼4000g/eq, 또한, Tg가 0℃ 이상인 우레탄계 수지와, 평균 입자 직경이 10㎛ 이하인 비도전성 필러를 포함하고, 상기 보호층의 전체 중량에 대한 상기 비도전성 필러의 중량 비율은 10∼40 중량%인 것을 특징으로 한다.
Provided is an electromagnetic wave shield film which is less likely to cause blocking when stored in a rolled form, and which has excellent moisture resistance and bending resistance. An electromagnetic wave shield film according to the present invention in which a protective layer and a shield layer are laminated is characterized in that: the protective layer includes a urethane resin having an acid value of 2,000-4,000 g/eq and a Tg of at least 0 °C, and a non-conductive filler having an average particle diameter of at most 10 μm; and the weight percentage of the non-conductive filler to the total weight of the protective layer is 10-40 wt%. |
