た。In recent years, as interest in environmental problems has increased, a method of making a styrene resin flame-retardant without using halogen has been investigated as a method of solving these drawbacks. However, it was usually necessary to fill the styrene resin material with a large amount of additives until flame retardancy of UL94V-0 level was obtained. Thus, there is a problem that the physical properties of the material are deteriorated when a large amount of the additive is filled.

を損ない、コストが高くなる。In the resin composition of the present invention, the blending amount of melamine phosphate as the component (b) is 10 to 60 parts by weight based on 100 parts by weight of the styrene resin as the component (a). If the amount is less than 10 parts by weight, the flame retardant effect is not sufficient, and if it exceeds 60 parts by weight, the mechanical properties of the composition are impaired, the mechanical strength is lowered, and the electrical properties are also lowered, which is not preferable. . It is preferably 25 to 40 parts by weight. The polyhydric alcohol as the component (c) is the same as the above (a).
It is 5 to 30 parts by weight with respect to 100 parts by weight of the component styrene resin. If the amount is less than 5 parts by weight, the flame retardant effect is not sufficient, and if it exceeds 30 parts by weight, the mechanical properties of the composition are impaired, the mechanical strength is lowered, and the electrical properties are also lowered, which is not preferable. . Preferably 10-20
Parts by weight. The blending amount of the silicone oil as the component (d) is 0 to 20 parts by weight, preferably 1 to 10 parts by weight with respect to 100 parts by weight of the styrene resin as the component (a). Even if silicone oil is not added, there is almost no effect on the flame retardant effect, but addition of silicone oil improves impact strength. On the other hand, if the amount exceeds 20 parts by weight, the mechanical properties of the composition are impaired and the cost increases. The amount of the molybdenum compound as the component (e) is 0.01 to 10 parts by weight based on 100 parts by weight of the styrene resin as the component (a).
It is preferably 0.5 to 5 parts by weight. If the blending amount of the molybdenum compound is less than 0.01 part by weight, a sufficient flame retardancy improving effect cannot be expected. On the other hand, if it exceeds 10 parts by weight, there is a problem in mechanical strength. The blending amount of the phosphate-based flame retardant compound as the component (f) is 0.1 to 20 parts by weight, preferably 5 to 10 parts by weight, based on 100 parts by weight of the styrene resin as the component (a). When the amount of the phosphate-based flame retardant compound is less than 0.1 part by weight, a sufficient flame retardancy improving effect cannot be expected. On the other hand, if it exceeds 20 parts by weight,
The heat distortion temperature is low, which is a practical problem. The blending amount of the fluorinated polyolefin as the component (g) is the same as in the above (a).
0.01 to 100 parts by weight of the component styrene resin
It is 10 parts by weight, preferably 0.1 to 1 part by weight. If the blending amount of the fluorinated polyolefin is less than 0.01 part by weight, the function of preventing dripping due to plasticization of the resin that occurs when the phosphate flame retardant compound is added is not sufficient. On the other hand, if it exceeds 10 parts by weight, the mechanical properties are impaired and the cost increases.
