    • The present disclosure relates to an aramid paper for a honeycomb, which is prepared by mixing, with an aramid floc, an aramid pulp having a fiber length equal to or longer than a predetermined length and a fibril development equal to or higher than a predetermined level, at a predetermined ratio, a wholly aromatic aramid paper for an electrical insulation paper having superior paper formation property and thus having uniform electrical insulation property, which is prepared by mixing an aramid pulp having a fines content equal to or higher than a predetermined ratio at a predetermined ratio, a laminated aramid paper having a uniform thermal expansion coefficient, uniform electrical conductivity and uniform thermal conductivity, which is prepared by laminating an aramid paper with superior paper formation property on an aramid paper with superior paper strength by calendering, and a method for preparing the same. The aramid paper according to the present disclosure is applicable to a material or a component which requires precision with little difference in physical properties such as a thermal expansion coefficient, electrical conductivity and thermal conductivity. Specifically, it is applicable to a honeycomb, an electrical insulation paper, a PCB substrate, etc. because it has superior paper strength and paper formation property. Moreover, the method for preparing an aramid paper can solve the problems of poor transfer of a base paper, nonuniformity of strength and aggregation between flocs.
    • 本发明涉及蜂窝用芳族聚酰胺纸,其通过将芳族聚酰胺浆与纤维长度等于或大于预定长度并且纤维发育等于或高于预定水平的芳族聚酰胺浆混合 以规定的比例混合芳香族含量为规定比例以上的芳族聚酰胺浆粕而成的电气绝缘纸,该纸用芳香族聚酰胺纸具有优异的造纸性, 通过压延加工在纸张强度优良的芳族聚酰胺纸上层叠具有良好纸形成性的芳纶纸而制得的具有均匀的热膨胀系数,均匀的导电率和均匀的导热率的层压芳纶纸以及方法 为了准备它。 根据本公开的芳族聚酰胺纸适用于要求精度的材料或部件,其物理性质诸如热膨胀系数,导电性和导热性之间的差异很小。 具体而言,由于纸力和纸形成性优异,因此适用于蜂窝,电绝缘纸,PCB基板等。 此外,制备芳族聚酰胺纸的方法可以解决原纸转印不良,强度不均匀和絮凝物之间聚集的问题。
