When the composition is burned, a large amount of soot is released and corrosive hydrogen halide gas is also generated. On the other hand, with metal hydrates added, since the metal hydrate has little aflammatory effect, it is necessary to incorporate a large amount, and adding a large amount may result in a decrease in the tensile properties of the resin composition or deterioration of cold resistance.

る。In the flame-retardant resin composition of the present invention, high flame retardancy is imparted to the polyolenoin resin by incorporating triallyl trimellitite. The flame retardant mechanism of triallyl trimellitite is thought to be due to a radical reaction between radical species generated by combustion of polyolefin resin and triallyl trimellitite, which suppresses volatilization due to lower molecular weight of the resin. . Therefore, when a flame retardant having another flame retardant mechanism is used in combination, the flame retardant effect is greatly enhanced.

。結果を別表に併せて示す。Resin compositions having the formulation shown in the attached table were prepared, and their flame retardance was evaluated using the M index, and at the same time, their tensile strength properties were determined. The results are also shown in the attached table.

好であることがわかる。As is clear from the attached table, products containing 0.1 to 30 parts by weight of triallyl trimellitite have excellent flame retardancy, and combination systems with metal hydrates such as aluminum hydroxide and magnesium hydroxide It can be seen that high flame retardance can be obtained even if the amount of metal hydrate blended is reduced, and the mechanical properties of the resin composition are also good.
