ABSTRACT:
A flame-retardant metal-coated fabric which not only has excellent electromagnetic wave shielding properties but has a high degree of flame retardancy without the necessity of containing a halogen compound or antimony compound. It is soft and suffers no deterioration of the metal coating even in long-term use. The flame-retardant metal-coated fabric comprises a metal-coated fabric and a flame-retardant coating layer formed on at least one side of the metal-coated fabric, the flame-retardant coating layer comprising a mixture (F) of the following components (A), (B), (C), (D) and (E):(A) a flame retardant selected from the group consisting of ammonium polyphosphate and melamine polyphosphate;(B) a flame-retardant aid selected from the group consisting of melamine, melamine cyanurate, and tris(2-hydroxyethyl)isocyanate;(C) a blowing agent selected from the group consisting of heat-expandable graphite, azodicarbonamide, and N,N′-dinitrosopentamethylenetetramine:(D) a phosphoric ester; and(E) a thermoplastic resin having a melting point of 70-130° C.,the ratio of (A):(B):(C):(D):(E) being 15-100:50-100:30-60:15-50:100 in weight ratio.
