A method for preparing an electromagnetic wave shielding material.

摘要

An electromagnetic wave shielding material comprises a composite carbon-resin compound obtained by reacting to proceed polymerization of a resin forming material with carbon powder intermixed therewith. The resulting compound has carbon powder substantially uniformly dispersed in the resin and exhibit superior electromagnetic wave shielding effect, in addition to good fire resistance. The resin may be phenol, melamine, furan or the like, and the carbon powder is preferred to be incorporated at a content of not less than 40% of the total weight.
