NONHALOGENATED FLAME RETARDANT COMPOSITION COMPRISING MATRIX RESIN, METAL HYDROXIDE-BASED INORGANIC FLAME RETARDANT AND PHENOLIC METAL DEACTIVATOR AND ELECTRIC WIRE FOR AUTOMOBILES USING THE COMPOSITION

摘要

PURPOSE: Provided are a nonhalogenated flame retardant composition and an electric wire for automobiles using the composition which is environmental-friendly and is improved in abrasion resistance, scratch resistance, hardness, heat resistance and extrusion. CONSTITUTION: The nonhalogenated flame retardant composition comprises 100 parts by weight of a matrix resin comprising a polyethylene-based resin and an ethylene copolymer resin in the ratio of 2:8 to 8:2; 50-200 parts by weight of a metal hydroxide-based inorganic flame retardant; 0.5-20 parts by weight of an antioxidant; and 0.1-3.0 parts by weight of a phenolic metal deactivator. Preferably the composition is crosslinked so as to have a three-dimensional network structure. The electric wire comprises an insulator(2) comprising the nonhalogenated flame retardant composition.
