Flame-retardant resin composition and insulated wire

Abstract

The present invention provides a flame-retardant resin composition having high flame retardancy and an insulated wire. The flame-retardant resin composition contains an olefin-based resin, a molybdateflame retardant, and a metal hydroxide. Content of the said molybdate flame retardant is 100 mass parts or more and 40 mass parts or less with respect to the said olefin resin. The specific gravity of the above molybdate flame retardant is below 4.0 g / cm3. The average particle size of the above molybdate flame retardant is 2.5 mum or less. The molybdate flame retardant preferably contains zincmolybdate. The molybdate flame retardant is preferably particles containing inorganic fine particles and zinc molybdate supported on the surface of the inorganic fine particles.

Description

technical field [0001] The present disclosure relates to a flame-retardant resin composition and an insulated wire. Background technique [0002] In order to improve the flame retardancy of the resin composition, a flame retardant is added to the resin composition. As flame retardants, metal hydroxides are used. Magnesium hydroxide, aluminum hydroxide, etc. are mentioned as a metal hydroxide. However, the flame retardancy of the resin composition cannot be sufficiently improved only by adding the metal hydroxide. Patent Document 1 discloses that magnesium hydroxide and the like are used in combination with molybdate as a flame retardant added to a resin composition.
