Conductive aramid paper and method for producing same

摘要

Provided is a conductive aramid paper comprising an aramid short fiber, an aramid fibrid, and a conductive filler, and having a density of 0.45 to 1.10 g/cm3, a tensile strength of 2.5 kN/m or higher, and a surface resistivity of 1.0×101 to 5.0×102Ω/□. This conductive aramid paper has an electric field relaxation function and an antistatic function enough to be favorably used as a material for reducing corona in rotating electrical machines, and also antistatic components for electrical and electronic devices, and sub-materials for processing or assembling any of these.

1. A conductive aramid paper comprising a mixture of
5 to 60% by weight of an aramid short fiber, 30 to 80% by weight of an aramid fibrid, and 1 to 30% by weight of a conductive filler, wherein the weight percentages are relative to the total weight of the aramid short fiber, the aramid fibrid, and the conductive filler, and wherein the conductive aramid paper has a density of 0.45 to 1.10 g/cm3, a tensile strength of 2.5 kN/m or higher, a surface resistivity of 1.0×101 to 5.0×102Ω/□, and a thickness of 20 to 100 μm.
