Abstract
[Problem] To provide a non-halogen flame-retardant resin composition which is free from environmental problems and has various characteristics such as high mechanical characteristics and flame retardancy, while providing a molded article thereof with good appearance at the time of extrusion molding; and an insulated wire / cable which has this resin composition. [Solution] A non-halogen flame-retardant resin composition of the present invention contains a predetermined amount of an ethylene-vinyl acetate copolymer, a polyethylene and / or an ethylene-alpha-olefin copolymer, an unsaturated carboxylic acid-modified polyolefin resin, a propylene resin, a predetermined amount of magnesium hydroxide, aluminum hydroxide, and a 1, 3, 5-triazine derivative compound. Since the vinyl acetate contained in the resin component is maintained at a constant amount and no halogen is contained, this flame-retardant resin composition is environmentally friendly and has various characteristics such as high mechanical characteristics and flame retardancy satisfying UL 1581, while providing a molded article thereof with good appearance at the time of extrusion molding.
Description
technical field [0001] The invention relates to a non-halogen flame-retardant resin composition and an insulated wire and cable with the resin composition. More specifically, it relates to a non-halogen flame-retardant resin composition used as an insulating coating material for electric wires or cables, and an insulated electric wire and cable having the resin composition. Background technique [0002] As insulating coating materials for electric wires and cables, polyvinyl chloride-based resins are widely used because they are low-cost, and have excellent properties such as flame retardancy and abrasion resistance in addition to heat resistance and moisture resistance. On the other hand, there is a problem that since the polyvinyl chloride resin contains halogen, the amount of smoke generated when burned by a fire or the like is large, harmful gases such as halogen gas are generated, or secondary gases are generated depending on the burning conditions. become the cause o...
