Weather-resistant flame-retardant polycarbonate (PC) composition, and preparation method and application thereof

The invention discloses a weather-resistant flame-retardant polycarbonate (PC) composition, and a preparation method and application thereof. A new PC composition is formed by adding a sulfonate flame retardant or a triazine addition type flame retardant, an acrylic ester core-shell anti-impact modifier, a hydroxyphenyl triazine ultraviolet absorbent, a composite antioxidant of hindered phenol antioxidant and phosphite ester antioxidant and a pentaerythritol lubricating agent into the PC. Compared with the prior art, the weather-resistant flame-retardant PC composition has low cost and high mechanical property, weather resistance and flame retardance. After pigment is added, the formed material is elegant.
