Abstract

본 발명은 폴리에스테르에 광 안정제와 산화 방지제를 함께 첨가하여 내후성, 광투과성 및 방진성을 크게 향상시킨 폴리에스테르 필름에 관한 것이다.The present invention relates to a polyester film in which a light stabilizer and an antioxidant are added to a polyester to greatly improve weather resistance, light transmittance, and dust resistance.

즉, 필름 구성 성분의 70중량% 이상이 폴리에틸렌 테레프탈레이트인 폴리에스테르로 제조된 필름에 있어서, 벤조트리아졸계나 벤조페논계의 자외선 흡수제, 또는 봉쇄된 아민계의 자외선 안정제를 포함하는 광 안정제와, 인계나 페놀계의 산화 방지제를 각각 0.01 내지 5.0중량% 함유하는 것을 특징으로 하는 본 발명의 폴리에스테르 필름은 내후성, 광투과성 및 방진성이 장기간 우수하게 유지되므로, 특히 농업용 온실, 축사 및 양어장 등의 피복재로 사용하기 적합하다.That is, in the film made from polyester whose 70 weight% or more of a film component is polyethylene terephthalate, the light stabilizer containing the benzotriazole type or the benzophenone type ultraviolet absorber, or the blocked amine type ultraviolet stabilizer, The polyester film of the present invention, which contains 0.01 to 5.0% by weight of phosphorus- or phenol-based antioxidant, respectively, has excellent weather resistance, light permeability, and dust resistance for a long time, and therefore, especially coating materials for agricultural greenhouses, barns, fish farms, and the like. Suitable for use as
