[0178] With the compounding amounts described in Table 1 and Table 2, polycarbonate resin, styrene-based resin, slipperiness imparting agent, and various additives were mixed with a mixer, and then melted and kneaded using a vented twin-screw extruder. Get pellets. Various additives to be used are pre-mixed with polycarbonate resin with a target concentration of 10 to 100 times the respective compounding amount, and then mixed with a mixer as a whole. The vented twin-screw extruder used was manufactured by Nippon Steel Works: TEX-30XSST (full meshing, same direction rotation, 2 flight screws). Extrusion conditions are discharge rate 20kg / h, screw rotation speed 150rpm, and vent vacuum 3kPa. In addition, extrusion temperature: from the first supply port to the second supply port is 280°C, from the second supply port to the die Some are 290°C. In addition, the reinforcing filler was supplied from the second supply port using the side feeder of the extruder, and the remaining p...

Abstract

The present invention relates to a glass fiber reinforced resin composition. The objective is to provide a resin composition based on flat cross section glass fiber reinforced thermoplastic resin and having excellent mechanical strength, small aeolotropism of mold shrinkage, good appearance and sliding characteristic. The resin composition contains (A) thermoplastic resin (component A) containing aromatic polycarbonate resin (component A-1); (B) flat cross section glass fibre (component B-1) that an average value of long diameters of the fibre cross section is 10-15[Mu]m, an average value of ratios of the long diameters and short diameters is 1.5-8, and filler material (component B-2), and (C) slide endowing agent (component C), wherein relative to 100 parts of component A by weight, the resin composition contains 1-150 parts of B-1 by weight, 0-150 parts of B-2 by weight, and 0.1-30 parts of C by weight.

Description

technical field [0001] The present invention relates to a glass fiber reinforced resin composition having improved dimensional accuracy and sliding properties. More specifically, it relates to a glass that is based on a thermoplastic resin containing a polycarbonate resin reinforced with flat cross-section glass fibers, has excellent mechanical strength, has small anisotropy in molding shrinkage, and has good appearance and sliding properties. Fiber reinforced resin composition. Background technique [0002] Thermoplastic resins reinforced with glass fibers are widely used because of their excellent mechanical strength and processability. In particular, polycarbonate resins have been used in various applications such as machine parts, automobile parts, electrical-electronic parts, and office equipment parts due to their excellent properties such as mechanical strength, dimensional stability, and flame retardancy. [0003] At present, for parts requiring sliding properties ...
