うという問題があった。(Prior art) In recent years, flame-retardant resin compositions used in various sheets, films, or as covering materials for IT wires and cables are made of halogen-free compositions to prevent smoke generation during combustion. , preventing the generation of corrosive hydrogen halide gas. As such a composition, a composition obtained by adding a hydrated metal compound such as magnesium hydroxide or aluminum hydroxide to a non-halogen resin, ie, a resin such as polyethylene or ethylene-ethyl acrylate, is generally used. However, a large amount of the hydrated metal compound must be added in order to obtain sufficient flame retardancy, and as a result, there is a problem in that the mechanical properties of the resulting composition are significantly reduced.
そこで、難燃効果の高い赤リンを単独あるいは水和金属
