NON-HALOGEN FLAME-RETARDANT RESIN COMPOSITION, METHOD FOR PRODUCING THE SAME AND ELECTRIC WIRE/CABLE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a non-halogen flame-retardant resin composition, which includes high mechanical strength and heat resistance without cross-linking with an electron beam, which can be extruded at high speed even if it is filled with a flame retardant at a high level, and which exhibits good elongation by the use of an ethylene-vinyl acetate copolymer cross-linked with a silane as a dispersion phase and an ethylene-ethyl acrylate copolymer as a continuous phase upon the formation of the dispersion phase in an olefinic resin matrix using a dynamic cross-linking technique, to provide a method for producing the resin composition, and to provide an electric wire/cable using the same.;SOLUTION: The non-halogen flame-retardant resin composition includes (A) 40-80 pts.mass of an ethylene-vinyl acetate copolymer, (B) 60-20 pts.mass of an ethylene-ethyl acrylate copolymer having a melting point of 100°C or higher, and (C) a metal hydroxide in an amount of 20-300 pts.mass based on 100 pts.mass of the sum total of the components (A) and (B). The ethylene-vinyl acetate copolymer (A) is cross-linked with a silane.;COPYRIGHT: (C)2011,JPO&INPIT
