2. Description of the Related Art Today,
Various types of thermoplastic synthetic resins are used as materials for household electric appliances, buildings, upholstery and automobile parts. However, most of thermoplastic synthetic resins are flammable, and this tendency is remarkable especially in polyolefin resins. Therefore, when a flame is brought close to a part of the molded product, the molded product has a drawback that it starts to burn and continues to burn naturally even if the flame is moved away after the start of combustion, and the use is limited to some extent.

Various methods have heretofore been proposed for imparting flame retardancy to resins. As a general method,
For example, a method is known in which a phosphorus compound and antimony trioxide or an organic halogen compound and a phosphorus compound are added to a resin in combination. However, in order to impart excellent flame retardancy by adding these compounds, it is necessary to add a large amount of the compounds, and as a result, the mechanical properties originally possessed by the resin and other desirable properties are desirable. The characteristics will be significantly reduced. Further, when the organic halogen compound is added to the resin, there are problems that a corrosive gas is generated at the time of resin molding and a toxic gas is generated at the time of combustion. Further, since the above compound is expensive, if it is used as a product, there is a cost problem of cost increase.
