Flame-retardant resin composition, and molded body, electric wire, and cable obtained using same

The purpose of the present invention is to provide: a polyethylene-based flame-retardant resin composition containing an inorganic flame retardant and a silicone acrylic graft copolymer resin that can improve flame retardancy and also improve sliding properties by adding a small amount of the resin composition; and a molded article obtained using the polyethylene-based flame-retardant resin composition. Provided is a flame-retardant resin composition containing (I) 100 parts by mass of a polyethylene resin; (II) 50-300 parts by mass of an inorganic flame retardant; and (III) 1-20 parts by mass of a silicone acrylic graft copolymer resin that is a copolymer of a polyorganosiloxane represented by formula (1) and at least one monomer selected from (meth) acrylate monomers, the mass ratio of the polyorganosiloxane to the (meth) acrylate unit being 50: 50-90: 10. 本发明的目的在于，提供含有无机阻燃剂和少量添加即可在提高阻燃性的基础上还提高滑动性的有机硅丙烯酸类接枝共聚树脂的聚乙烯系阻燃性树脂组合物、以及使用其得到的成形体。本发明提供阻燃性树脂组合物，其含有(I)聚乙烯系树脂100质量份；(II)无机阻燃剂50～300质量份；以及(III)有机硅丙烯酸类接枝共聚树脂
