Abstract

본 발명은 폴리에스테르 내부에 리튬과 인화합물로부터 미세입자를 석출시키는 동시에 무기활제로서 알루미나를 첨가하고, 결정화촉진제의 사용을 포함하는 이축배향 폴리에스테르 필름의 제조방법에 관한 것이다.The present invention relates to a method for producing a biaxially oriented polyester film comprising precipitation of fine particles from lithium and phosphorus compounds in a polyester, simultaneously adding alumina as an inorganic lubricant and using a crystallization accelerator.

즉, 디메틸테레프탈레이트와 에틸렌글리콜에 리튬염을 가하여 에스테르 교환반응을 수행하고, 여기에 인화화물 및 트리메틸 포스페이트 또는 트리에틸포스페이트를 가하고, 1,5-나프탈렌디설폰산 나트륨을 폴리에스테르 총중량의 0.05 내지 5.0중량%로 첨가하여 중축합반응을 수행하고, 평균입경 0.1 내지 3.0㎛, 모스경도 7이상인 알루미나를 다음 조건을 만족하는 범위의 양으로 첨가하여 폴리에스테르를 제조하고, 이를 용융압출후 이축연신하는 것을 포함하여 제조되는 이축배향 폴리에스테르 필름은 이활성, 내스크래치성 및 내마모성이 양호하며, 특히 이를 자기기록매체의 베이스필름에 적용하였을 때 전자특성이 우수하다.That is, a transesterification reaction is performed by adding lithium salt to dimethyl terephthalate and ethylene glycol, and a phosphide and trimethyl phosphate or triethyl phosphate are added thereto, and 1,5-naphthalenedisulfonate sodium is 0.05 to 5.0 of the total weight of polyester. The polycondensation reaction was carried out by adding in weight%, and the alumina having an average particle diameter of 0.1 to 3.0 µm and a Mohs hardness of 7 or more was added in an amount satisfying the following conditions to prepare a polyester, followed by biaxial stretching after melt extrusion. The biaxially oriented polyester film prepared in the present invention has good biactivity, scratch resistance and abrasion resistance, and in particular, when applied to the base film of the magnetic recording medium, it has excellent electronic properties.

0.125〈Mu/MAl〈0.850 여기에서 Mu 및 MAl는 각각 리튬 및 알루미나의 첨가량이다.0.125 < Mu / M Al < 0.850 where Mu and M Al are addition amounts of lithium and alumina, respectively.
