Background
Polycarbonate (PC) is thermoplastic engineering plastic with excellent physical and mechanical properties, has excellent mechanical properties and flame retardance, and has unique application prospect in some fields with high requirements on appearance and high requirements on flame retardance; however, due to the existence of a benzene ring structure in a polycarbonate molecular chain, the rigidity of the whole molecular chain is high, so that the movement of the chain segment is hindered, the residual internal stress in the injection molding process is difficult to release, and cracking is easily caused under the condition of external force impact.
In the research, the filler is dispersed in the resin by adding, so that the flame retardant property of the system can be improved; in a more important aspect, when the material is impacted by the outside, the material can be used as a stress concentration point to cause crazing to dissipate energy without causing cracking of the product. However, the added fillers are mostly alkaline substances, which can cause PC degradation and result in silver wire appearance.
