Description

570954 A7 B7 V. Description of the invention (1) Technical field (please read the precautions on the back before filling this page) The present invention relates to a polycarbonate resin composition. More specifically, it relates to a polycarbonate resin composition that has excellent fluidity, impact resistance, and flame retardancy. Description of related technologies Polycarbonate resins have excellent mechanical strength (especially impact resistance), electrical properties and transparency, and have been used as engineering plastics. They are widely used in various fields such as office automation equipment, such as copying machines and printing machines. Electrical and electronic appliances and automobiles. Among these fields, where flame retardance is required, the main fields are office automation equipment and electrical and electronic appliances. Among various thermoplastic resins, polycarbonate resins have high oxygen index and self-extinguishing properties. However, the level of flame retardancy required in the field of office automation equipment and electrical and electronic appliances is generally as high as V-0, according to the UL 94 standard. To impart this level of flame retardancy, the addition of flame retarders and flame retarder auxiliaries is considered necessary. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs However, the use of this additive results in reduced impact resistance or heat resistance. To solve this problem, a composition containing polycarbonate resin, polycarbonate-polyorganosiloxane copolymer, and polytetrafluoroethylene has been disclosed (J P -A — 8-81620). On the other hand, flame retarding materials have recently been required, and they can be molded into a large-sized thin product such as a casing of a copying machine or a printing machine and have excellent fluidity.
