Abstract
본 발명은 자기기록매체의 제조방법에 관한 것으로, 자성도료에 혼합되는 결착제로서 분자량이 10,000∼20,000이고, 하이드록실기 10wt% 이상 함유하는 폴리우레탄을 사용하여 자기기록매체를 제조하는 것으로, 이러한 본 발명은 고주파에서의 출력 향상, 도막의 내구성, 내환경성이 향상되는 자기기록매체를 제공할 수 있게 된다.The present invention relates to a method of manufacturing a magnetic recording medium, which is to prepare a magnetic recording medium using a polyurethane having a molecular weight of 10,000 to 20,000 and containing 10 wt% or more of hydroxyl groups as a binder to be mixed with a magnetic paint. The present invention can provide a magnetic recording medium having improved output at high frequency, durability of a coating film, and environmental resistance.
