30 to 70 parts by weight of S resin, 70 to 30 PC resin
A range of parts by weight is preferred. If the amount of the ABS-based resin is larger than this, it is not preferable because the absolute value of the impact strength decreases and the drawdown due to the heating of the heater during the secondary processing increases. Furthermore, when imparting flame retardancy, it is necessary to add a large amount of a flame retardant, and as a result, the impact strength may be more significantly reduced.

In the present invention, the main composition is obtained by blending or melt-kneading the above-mentioned PC-based resin and ABS-based resin in the above-mentioned weight ratio range. The composition was extruded into a plate with a thermoplastic resin extruder, and was subjected to a dynamic viscoelastic spectrometer stretching method at a frequency of 1 Hz.
Storage elastic modulus in the MD and TD directions is 17
It has been found that good secondary workability can be obtained by setting 1.00 × 10 6 Pa or more at 0 ° C. and 2.00 × 10 5 Pa or more at 200 ° C. The “MD direction” means a flow direction during extrusion molding, and the “TD direction” means a direction orthogonal to the flow.

The pressure between 200 Pa and 1.00 × 10 7 Pa sharply decreases as the temperature rises.
It drops to 0 × 10 5 Pa or less. Such a sudden change in the storage elastic modulus in the molding temperature range appears as sensitivity to uneven temperature during the heating of the secondary processing, and the molding becomes inconsistent due to remarkable thickness unevenness or breakage during molding. cause. Further, a low absolute value of the storage elasticity indicates an increase in fluidity, which causes an increase in drawdown and an inability to mold due to an insufficient breaking elongation during molding.
