Problems solved by technology

[0003] However, since vinyl chloride resin has the other side of flame retardancy, it contains halogen elements in its molecules, so there is a problem that toxic halogen gas is released into the atmosphere when a vehicle fires or is incinerated.

Abstract

A halogen-free heat aging-resistant flame-retardant resin compound includes a mixture of 100 parts by mass of polyolefin-based resin, 100 to 250 parts by mass of metal hydroxide, and 2 to 5 parts by mass of an antioxidant including a first antioxidant having a melting point of not less than 200 degrees Celsius and a mean particle diameter of not greater than 10 [mu]m solely or a combination with a second antioxidant, and the mixture is cross-linked.

Description

technical field [0001] The present invention relates to a non-halogen heat aging resistant flame retardant resin composition which is excellent in flame retardancy, heat aging resistance and safety and is useful as a cable insulating material, an electric wire and a cable using the same. Background technique [0002] Conventionally, vinyl chloride resins excellent in flame retardancy have generally been widely used as insulating coating materials for insulated electric wires used for wiring of railway vehicles and the like. [0003] However, since vinyl chloride resin has the other side of flame retardancy and contains a halogen element in its molecule, there is a problem that toxic halogen gas is released into the atmosphere when a vehicle fires or is incinerated and discarded. [0004] Against such a background, in recent years, the development of a non-halogen flame-retardant resin composition in which a polyolefin-based resin is used as a base resin and a metal hydroxide...
