A flame-retardant resin composition which comprises 100 parts by weight of a polyolefin resin, 50 to 300 parts by weight of aluminum hydroxide and/or magnesium hydroxide, and 0.1 to 100 parts by weight of a block copolymer made up of at least one polymer block comprising 50 to 100 mol% olefin monomer units and at least one polymer block comprising 0. 1 to 100 mol% vinyl monomer units having at least one functional group selected among carboxyl, epoxy, hydroxy, and carboxylic anhydride groups and groups represented by general formula -Si-R1(R2)(R3) (wherein R1, R2, and R3each represents halogeno, vinyl, alkyl, or alkoxy). The composition is excellent in all of melt moldability, flame retardancy, and mechanical properties. A flame- retardant material obtained by melt- molding the flame-retardant resin composition is suitable for use in various applications where flame retardancy is required, such as covering materials for electric wires, electrical insulating materials, building gaskets, building partitioning materials, flooring materials, wall materials, and automotive parts. |
