The talc in each of the examples and comparative examples was the one having the composition shown in Table 1. In Table 1, "Fe + Al + Ca" and "Fe + Al" Represents the total content of Fe 2 O 3 , Al 2 O 3 and CaO, and the total content of Fe 2 O 3 and Al 2 O 3 with respect to the total solid content of talc. Is a value obtained by analysis according to JIS M8851, and the particle diameter is a value obtained by measurement by laser diffraction method.
The obtained resin composition (pellets) was subjected to the following evaluation tests.
(1) Melt viscosity
The pellet the monolithic capillary rheometer: in (Co., Ltd. Toyo Seiki Seisakusho caviar manufacture pillow Graf 1D piston diameter 10mm) of the conditions, the cylinder temperature of the melting point + 20 ℃, 1000sec -1 shear rate using, ISO 11443 The apparent melt viscosity was measured. For the measurement, an orifice having an inner diameter of 1 mm and a length of 20 mm was used. The measurement results are shown in Table 1.
(2) Blister test
The pellets were molded into 1/32 combustion test pieces (with welds) using an injection molding machine (SE100DU, manufactured by Sumitomo Heavy Industries, Ltd.) under the condition that the molding cycle was 20 seconds. The resulting test piece was sandwiched in a hot press at a specified temperature for 5 minutes, and then the surface was observed. The maximum temperature at which blistering did not occur on the surface was investigated as BFT (Blister Free Temp). The specimen divided by the welded portion was set as the specimen, and the specified temperature was set in the range of 250 to 300 DEG C every 10 DEG C, and the measurement was carried out. The measurement results are shown in Table 1.

The pellets were molded under the condition that the number of screw revolutions was 150 rpm using an injection molding machine (SE30DUZ, manufactured by Sumitomo Heavy Industries, Ltd., screw diameter Φ : 18 mm, weighing stroke length: 55 mm) And an average value was obtained. The obtained values are shown in Table 1. It is judged that the molding processability is good when the weighing time is short.
In Table 1, in all of Examples 1 to 6, the blister test result is 270 ° C or more. Therefore, it can be seen that the heat resistance is excellent and the molding processability is excellent because the measurement time is 21 seconds or less . On the other hand, in Comparative Examples 1 to 5, the blister test results were lowered to 260 占 폚 except for Comparative Example 3, and all of the metering time exceeded 22 seconds, so that the moldability and the heat resistance were not simultaneously satisfactory.
