Title:
ARAMID PAPER, MANUFACTURING METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/190694
Kind Code:
A2
Abstract:
The present invention relates to: aramid paper for a honeycomb, which is manufactured by mixing, with aramid flock, aramid pulp having a fiber length equal to or longer than a predetermined length and a fibril developed at a level equal to or higher than a predetermined level, at a predetermined rate; wholly aromatic aramid paper for an electrical insulating sheet, the paper having excellent paper formation and thus having a uniform electrical insulation property, and being manufactured by mixing aramid pulp having fines, the content of which is equal to or more than a predetermined rate, at a predetermined rate; laminated aramid paper which has a uniform thermal expansion coefficient, uniform electrical conductivity, and uniform thermal conductivity, and is formed by laminating, through calendaring, aramid paper having excellent paper formation on aramid paper having excellent paper strength; and a method for manufacturing the same. The aramid paper according of the present invention can be applied to a material or a component, which requires precision and should have a little difference in a physical property, such as a thermal expansion coefficient, electrical conductivity, or thermal conductivity. More particularly, the aramid paper has excellent paper strength and excellent paper formation and thus can be applied to a honeycomb, an electrical insulating sheet, a PCB substrate, etc. Moreover, the method can remove poor transfer of base paper, non-uniformity of strength, and cohesion between flocks in manufacturing aramid paper.
