Abstract

본 발명은 도포형 자기기록 매체의 제조방법에 관한 것이다. 자성체, 결합체, 카본블랙, 연마제 및 유기용제를 함유하는 자성도료를 비자성 지지체 위에 도포, 건조, 캘린더링, 슬리팅하는 것을 포함하는 자기기록 매체를 제조하는 방법에 있어서, 상기 자성도료가, 상기 유기용제의 일부에 결합제를 첨가하여 혼합 유기용제를 준비하는 단계, 배치식 혼련 혼합기에서 상기 혼합 유기용제의 일부를 상기 카본블랙 고형분에 미량씩 투입하여 혼련하는 단계 및 상기 혼합 유기용제의 나머지를 상기 혼련물에 미랑씩 투입, 희석하여 카본블랙 혼련 희석물을 제조하는 단계, 상기 자성체에 상기 유기용제를 투입하여 혼련, 희석하는 단계 및 상기 자성체의 혼련 희석물에 상기 카본블랙 희석물, 상기 결합제, 상기 연마제 및 상기 유기용제를 첨가하는 단계를 통하여 얻어지는 것을 특징으로 하는 도포형 자기기록 매체는 카본블랙을 첨가 및 첨가하지 않은 경우의 장점을 모두 가짐으로써 자기특성, 주행성, 표면평활성 등의 각 특성이 우수하다.The present invention relates to a method of manufacturing a coated magnetic recording medium. A method of manufacturing a magnetic recording medium comprising applying, drying, calendering, and slitting a magnetic paint containing a magnetic material, a binder, carbon black, an abrasive, and an organic solvent on a nonmagnetic support, wherein the magnetic paint is the Preparing a mixed organic solvent by adding a binder to a portion of the organic solvent, kneading the mixed organic solvent by adding a small amount of the mixed organic solvent to the carbon black solids in a batch kneading mixer, and mixing the rest of the mixed organic solvent with the Preparing a carbon black kneading dilution by feeding and diluting the kneaded material into each kneaded mixture, kneading and diluting the organic solvent by adding the organic solvent, and diluting the carbon black dilution, the binder, and the kneading dilution of the magnetic substance. The coated magnetic recording medium is obtained by adding the abrasive and the organic solvent. By having both the advantages of adding and not adding carbon black, the magnetic properties, running properties, surface smoothness and the like are excellent.
