Description
본 발명은 폴리에스테르/폴리카보네이트 블렌드에 관한 것으로, 좀 더 상세하게는, 열적 안정성 및 색상 안정성이 우수한 폴리에스테르/폴리카보네이트 블렌드에 관한 것이다.The present invention relates to a polyester / polycarbonate blend, and more particularly to a polyester / polycarbonate blend having excellent thermal stability and color stability.
.폴리에스테르는 기계적 강도, 내열성, 투명성 및 가스베리어성이 우수하기 때문에, 특히 주스, 청량 음료, 탄산. Polyesters are excellent in mechanical strength, heat resistance, transparency and gas barrier properties, and therefore, in particular, juices, soft drinks,
음료 등의 음료 충전용 용기나, 포장용 필름, 오디오, 비디오용 필름 등의 소재로서 가장 적합하여 대량으로 사It is most suitable as a container for beverage filling such as beverage, packaging film, audio and video film, etc.,
용되고 있다. 폴리에스테르의 시트(sheet)나 판재는 투명성이 양호하고 기계적 강도도 우수하여 케이스, 박스,. The sheet or plate of polyester has good transparency and excellent mechanical strength,
파티션, 점포선반, 보호패널, 블리스터 패키징, 건축자재, 인테리어 내외장재 등의 재료로 넓게 사용되고 있다.Partitions, shop shelves, protective panels, blister packaging, building materials, and interior and exterior materials.
최근 주목을 받고 있는 새로운 폴리에스테르의 용도로서 두꺼운 플라스틱 시트를 성형한 후, 이를 건축 내장재,As a new polyester that has recently attracted attention, a thick plastic sheet is molded,
성형간판 등으로 사용하는 예가 늘어나고 있다. 그러나, 폴리에스테르는 시트 용도로 쓰이는 다른 경쟁수지인There is an increasing number of cases of use as a molded signboard or the like. However, polyester is another competitive resin used in sheet applications
아크릴(PMMA)이나 폴리카보네이트(PC)에 비해 내열성이 낮아, 계절에 따른 온도 변화가 심한 옥외용 외장재로It has a lower heat resistance than acrylic (PMMA) or polycarbonate (PC)
사용하기에 부적합한 경우가 있다. 이에, 폴리에스테르의 부족한 내열성을 향상시키기 위해 여러 가지 기술적 시도들이 있었으며, 그 중에서 대표적인 방법으로 PC와의 블렌딩 기법이 있다.It may not be suitable for use. Therefore, there have been various technical attempts to improve the heat resistance of the polyester. Among them, a blending technique with PC is a representative method.
따라서, 본 발명의 목적은, 열적 안정성 및 색상 안정성이 우수한 폴리에스테르/폴리카보네이트 블렌드를 제공Accordingly, an object of the present invention is to provide a polyester / polycarbonate blend excellent in thermal stability and color stability
하는 것이다..
