[0236] (Examples 1 to 11, Comparative Examples 1 to 11)
[0237] [Made of resin composition pellets]
[0238] The above components were compounded in the ratio (all parts of mass) described in Table 2-3, and after uniform mixing in the roller mixer, the melt kneading was carried out from the hopper.
[0239] As an extruder, the twin-screw extruder (TEX25αIIi, L / D = 52.5) is used in Japanese steel, and the drum speed is 200 rpm, the cylinder temperature is 280 ° C, and the discharge amount is 25 kg / hour. out. The extruded wire was quenched in the water tank and pelletized with a granulator.
[0240] After 5 hours, the pellet obtained in the above manufacturing method was dried at 120 ° C for 5 hours, NEX80 injection molding machine made by the daily resin Industrial Co., Ltd., at a temperature of 280 ° C, the mold temperature of 100 ° C, injection speed of 30 mm / s, Under the conditions of 90 MPa, it is formed into an ISO dumbbell test piece forming with a thickness of 4 mm....
