Production method and resin composition pellet of fibrous bulking agent high density combination resin composition

摘要

The resin composition pellet where as for this invention, the long fibrous bulking agent is combined in high density, is dispersed uniformly is offered. Thermoplastic resin (A)55 - 20 weight %, fibrous bulking agent (B)45 above length 1mm - 80 weight % (here, resin (A) and fibrous bulking agent (B) as for total 100 weight % is.)Supplying to the extruder, it pushes out from the die/di, the occasion where the resin composition pellet is produced, the resin (A) it supplies part (x) from the resin feed mouth of the extruder, from the resin feed mouth from the side feed mouth which is provided in the extrusion direction rear, the fibrous bulking agent (B) and the resin (A) in order for mass ratio x/(1-x) to become with 97/3 - 50/50, it supplies the remainder (1-x), to pellet converts.
