[0189] With the compounding amounts listed in Tables 1 and 2, polycarbonate resin, styrene-based resin, reinforcing filler, phosphate-based flame retardant, and various additives were mixed with a blender, and then vented biaxial The extruder performs melt kneading to obtain pellets. Each of the various additives used is pre-mixed with the polycarbonate resin based on the concentration of 10 to 100 times the compounding amount, and then the whole is mixed with a blender. The vent type twin-screw extruder is made by Nippon Steel Works: TEX-30XSST (full meshing, same direction rotation, 2 screws). Extrusion conditions are discharge rate 20kg / h, screw rotation speed 150rpm, and vent vacuum 3kPa. In addition, the extrusion temperature is 280°C from the first supply port to the second supply port, and 280°C from the second supply port to the second supply port. The die part is 290°C. In addition, the reinforcing filler was supplied from the second supply port using the side feede...

Abstract

The invention provides an electrical and electronic equipment part formed by the injection moulding of a glass fibre reinforced resin composition, wherein the resin composition containing a flat-section glass fibre reinforced polycarbonate resin is takes as a matrix, so that the electrical and electronic equipment part has excellent mechanical strength, less anisotropy of the form shrinkage and good flowability and flame resistance. The electrical and electronic equipment part is formed from the glass fibre reinforced resin composition comprising 40 to 65% by weight of thermoplastic resin (component A) and 35 to 60% by weight of reinforced filling materials (component B), and 1 to 30 weight portions of organic phosphate ester flame retardant (component C) based on 100 weight parts of the thermoplastic resin and the reinforced filling materials, the reinforced filling materials (component B) comprise flat-section glass fibre (component B-1) with the mean value of the long diameter of the fiber section being 10 to 50 mu m and the mean value of the ratio of the long diameter to the short diameter being 1.5 to 8, and other filling materials (component B-2) except the component B-1, the weight ratio of the component B-1 to the component B-2 is (10 to 90) to (100 to 0).

Description

technical field [0001] The present invention relates to electrical and electronic equipment components (hereinafter also referred to as electrical and electronic equipment components) formed of a glass fiber-reinforced resin composition. More specifically, it relates to a thermoplastic resin containing a polycarbonate resin reinforced with flat cross-section glass fiber as a matrix, which has high rigidity and high dimensional stability, and further has good flame retardancy. Combination of glass fiber-reinforced resins Components of electrical and electronic equipment formed of substances. Background technique [0002] Thermoplastic resins reinforced with glass fibers are widely used because of their excellent mechanical strength and processability. In particular, polycarbonate resins are used in various applications such as mechanical parts, automobile parts, electrical and electronic parts, and office equipment parts due to their excellent properties such as mechanical s...
