が有ることが知られている。2. Description of the Related Art Conventionally, polyethylene and polypropylene are semi-crystalline and extremely flammable. Therefore, halogen-based flame retardants and Sb
It has been common practice to use 2 O 3 in combination to make it flame-retardant. However, it has been reported that these flame retardants may generate substances harmful to the human body such as dioxin and halogen when burned, and Sb 2 O 3 is becoming a problem as an environmental destructive substance. for that reason,
There is a demand for non-halogen, non-antimony conversion of flame retardants for polyolefins. Polyolefins (especially polyolefins for injection molded products) are difficult to flame retardant except for halogen-based flame retardants due to their properties. However, flame-retarding technology using a large amount of metal hydroxides such as magnesium hydroxide, or A flame-retardant technology based on a synergistic effect of metal hydroxide and carbon black is already known, and is used for electric wires and cables. However, when a large amount of a metal hydroxide is blended with the polyolefin, problems such as poor appearance, reduced physical properties (mechanical strength, particularly reduced impact strength), or cost arises. In order to reduce the amount of the metal hydroxide, red phosphorus, carbon black, combined use of auxiliary agents such as metal oxides has been reported, but its flame retardant level is still lower than that of halogenated flame retardants. Low and hardly used in the field of injection molding. Furthermore, when red phosphorus is used in combination, the odor of phosphorus causes a problem in productivity during granulation and molding, and the molded product is not preferable as compared with ordinary polyolefin molded products. Japanese Patent Application Laid-Open No. 7-33990 discloses that when red phosphorus is used in combination, the addition of an oxygen-containing resin represented by EVA (ethylene-vinyl acetate copolymer) significantly improves flame retardancy. Although reported in JP-A-7-133370 and the like, it is known that EVA has low heat resistance and has disadvantages such as odor and reduced rigidity.
