(57) [Summary] [Purpose] Regarding polyolefin resin compositions used as insulating materials for electric wires, cables, etc., while taking advantage of their characteristics of being light and strong, they also generate a large amount of corrosive gas and smoke during combustion. Disclosed is a flame-retardant polyolefin-based resin composition that is flame-retardant. [Composition] 100 parts by weight of polyolefin, 1 to 20 red phosphorus By weight, the expansibility upon rapid heating (80 to 1000 ° C) is C 100 times or more in the axial direction and 80 by classification 1 heat-expandable graphite containing 80% or more of mesh-on -30 parts by weight are mixed to form a resin composition. |
