Description
The present invention relates to a polycarbonate resin composition, and more particularly, to a polycarbonate resin composition which prevents hydrolysis of a polycarbonate resin and provides excellent heat and moisture resistance while providing mechanical properties equal to or greater than that of the polycarbonate resin composition.
Background Art [0002] Polycarbonate resins are well known as thermoplastic resins having excellent mechanical properties such as impact strength and excellent flame retardancy, dimensional stability, heat resistance and transparency, and are widely applied to exterior materials and automobile parts of electrical and electronic products.
However, polycarbonate resins used as exterior materials for electric and electronic products and automobiles are inevitably affected by temperature and humidity depending on the surrounding environment during use, and fatigue breakdown and brittle fracture phenomenon are accelerated under such conditions. Particularly, when exposed to moisture, the carbonic ester group in the polycarbonate resin reacts with moisture to progressively hydrolyze and hydrolyze to lower molecular weight, thereby increasing fluidity, and various properties such as impact strength and tensile strength The problem of degradation occurs, and it is never recovered because it is irreversible.
The hydrolysis of polycarbonate resin greatly affects the molecular weight of the polycarbonate resin and the content of the flame retardant. The smaller the molecular weight of the polycarbonate resin, the greater the tendency to aging and the lowering of physical properties is accelerated. However, if the molecular weight of the polycarbonate resin is increased or the content of the flame retardant which serves as plasticizer is reduced, it is difficult to obtain sufficient flow in the case of large injection molding. Accordingly, there is a demand for a method capable of preventing the hydrolysis of the polycarbonate resin and continuing its physical properties.
The present invention relates to a polycarbonate resin composition, and more particularly, to provide a polycarbonate resin composition which is excellent in anti-wet heat characteristics by preventing hydrolysis of a polycarbonate resin while providing equal or more mechanical properties.
