The invention discloses a carbon nanotube-reinforced flame-retardant polycarbonate for laser marking and application thereof. The carbon nanotube-reinforced flame-retardant polycarbonate for laser marking comprises the following components: polycarbonate pellets, polycarbonate powder, carbon nanotubes, a primary flame retardant, an auxiliary flame retardant, a lubricant, an anti-aging additive, an anti-dripping agent and a laser marking additive. The primary flame retardant is a polyphosphazene flame retardant, and the auxiliary flame retardant is a sulfonate flame retardant. The invention also discloses a preparation method of the flame-retardant polycarbonate and its application in preparing casings for outdoor electronic products. By adding carbon nanotubes as reinforcements, the laser-markable flame-retardant polycarbonate material of the invention has significantly improved mechanical properties, excellent flame retardancy and laser marking effect, and can be applied to electronic product casings with high weather resistance requirements.
