Abstract

본 발명은 자기기록 매체의 제조 방법에 관한 것이다. 배치식 혼련혼합기에서 자성체와 결합제의 고형분을 혼합하는 단계, 상기 혼합물에 유기용제를 10 내지 20회에 걸쳐 분할 투입하면서 혼련하는 단계, 상기 단계에서 얻어진 혼련물에 결합제를 함유한 유기용제를 30 내지 90단계로 분할해서 가하여 희석하는 단계, 및 상기 희석되어진 혼련물을 분산기로 분산시켜 얻어진 분산액을 기재상에 도포, 건조하는 단계를 포함하는 방법에 의해 제조된 자기기록 매체는 지지체 위에 도포되어진 자성도막내의 충진성이 향상되어 자기특성, 전자변환특성 등이 뛰어나다.The present invention relates to a method of manufacturing a magnetic recording medium. Mixing the solids of the magnetic substance and the binder in a batch kneading mixer, kneading the mixture by dividing the organic solvent into the mixture 10 to 20 times, and adding the organic solvent containing the binder to the kneaded obtained in the step 30 to 30 The magnetic recording medium produced by the method comprising the steps of dividing into 90 and diluting, and applying and drying the dispersion obtained by dispersing the diluted mixture with a disperser on a substrate, has a magnetic degree applied to the support. The filling property in the film is improved, and the magnetic properties and the electron conversion characteristics are excellent.
