十分な難燃効果が得られ、この無機難燃剤配合に起因す
る機械的特性等の低下も少ないものとなる。The amount of the inorganic flame retardant to be blended varies depending on the degree of flame retardancy required, but is usually 50 to 200 parts by weight per 100 parts by weight of the polyolefin resin. If it is less than 50 parts by weight, the flame retardant effect will be insufficient, and if it exceeds 200 parts by weight, the mechanical properties etc. of the composition will deteriorate rapidly, which is disadvantageous. In the composition of this invention, flame retardancy is improved by adding 1.3.5-1-phosphoruskabutotriazine, which will be described later, so the amount of this inorganic flame retardant may be relatively small. A sufficient flame retardant effect can be obtained by adding about 100 parts by weight of the metal hydroxide, and there is little deterioration in mechanical properties etc. due to the addition of the inorganic flame retardant.

If it is less than 1 part by weight, no flame retardant effect will be imparted, and if it exceeds 1 part by weight, the degree of deterioration of the mechanical properties etc. of the composition will be large, which is disadvantageous.

Good flame retardancy is obtained by incorporating 1-phosphorus-kabutotriazine, and at the same time, even higher flame retardance is obtained by the presence of an inorganic flame retardant. Therefore, it is possible to reduce the amount of inorganic flame retardant added, resulting in a composition that has high flame retardancy and also has good mechanical properties, cold resistance, etc. Further, since no halogen-containing compound is present in the composition, no harmful corrosive combustion gas is generated during combustion.

。Further, the flame retardant resin composition of the present invention may be used in combination with other flame retardants, thereby providing a higher degree of flame retardancy. Examples of such flame retardants include carbon black and red phosphorus. Further, depending on the use of the composition, a halogen flame retardant may be added.
