Document Type and Number:
WIPO Patent Application WO/2020/011058
Kind Code:
A1
Abstract:
Disclosed by the present invention is a polycarbonate composition, comprising the following components according to parts by weight: a, polycarbonate 0.5-98.5 parts; b, a sulfonate flame retardant 0.15-0.95 parts; c, a synergistic flame retardant 0.03-0.72 parts; d, siloxane 0.04-1.1 parts; e, an anti-dripping agent 0.02-1 parts. In the present invention, a specific content and specific type of anti-dripping agent, and a specific content of polycarbonate, sulfonate flame retardant, synergistic flame retardant and siloxane are selected to be added into a polycarbonate composition formulation, and thus a good flame retardant and drip resistance effect may be attained at a lower combustion melt viscosity, while the polycarbonate composition still has good flame retardancy and thermal stability, as well as molding appearance, in case of a flame retardant film having a thickness of 0.40 mm.
