加して難燃化するべく配合検討をした。Polyethylene, ethylene-vinyl acetate copolymers, and the like have excellent electrical performance and can be crosslinked by electron beams, so they are widely used as insulating materials for internal wiring in equipment. However, recently, high flame retardancy has been required for wires for internal wiring in devices such as TV sets and audio equipment, and it has become necessary to consider making them flame retardant (for example, UL standard FR-1). . 25 We investigated the formulation of polyethylene, ethylene-vinyl acetate copolymers, etc. by adding rogens (e.g., chlorinated paraffins, aromatic bromides, aromatic chlorides, etc.) to make them flame retardant.
ところが、こうした難燃配合では、熱老化性能に問題が

３０Ｍｒａｄ照射した。However, it has been found that such flame-retardant formulations have problems with heat aging performance. That is, formulations that passed the UL standard flammability test did not pass the aging test specification.
Therefore, we investigated various ways to improve the aging performance of flame-retardant formulations. As a result, flame retardant compounds are pre-mixed with triazoles, thiazoles (e.g. pen 35 zotriazole, mercaptobenzothiazole, mercapto-acetylaminotriazole, etc.) or organic nitro compounds (e.g. hexamethyleneimine dinitrobenzoate, m-
They discovered that by adding nitrobenzohydrazide (nitrobenzohydrazide, etc.), it was possible to make a flame-retardant insulated wire that satisfactorily satisfies heat aging test standards, and completed the present invention. Example A copper wire with an outer diameter of 0.813 mm was extruded and coated with Conno Mound having the composition shown in Table 1 (thickness: 0.81!t).
We made a 4TfUrL insulated wire and used an electron beam accelerator to
It was irradiated with 30 Mrad.
