Abstract

The invention discloses a flame-retardant polycarbonate material for electronic products and a preparation method of the flame-retardant polycarbonate material. A coating mainly comprises polycarbonate, polybutylene terephthalate, methylphenyl silicone resin, polysiloxane, triphenylphosphine oxide, an anti-dripping agent, a toughening agent, an antioxidant and a heat stabilizer. The flame-retardant polycarbonate material provided by the invention has good flame retardancy, excellent impact resistance, good light-shielding effect, lower toxicity in exposure to a high temperature than that of aconventional heat-emitting flame-retardant polycarbonate material, environmental protection and safety; housings of electronic products processed by the flame-retardant polycarbonate material have flame retardancy meeting requirements on flame retardant rating.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a flame-retardant polycarbonate material for electronic products and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is one of the five widely used engineering plastics. It has comprehensive and balanced mechanical, electrical and heat resistance properties. It is especially famous for its excellent impact strength and creep resistance, high light transmittance and good mechanical properties. In particular, the impact toughness is the best among engineering plastics. Due to the excellent properties of PC, its products and their blended materials have been widely used in electronic products. [0003] Polycarbonate (PC) has a certain self-extinguishing property and emits CO2 when burning, and its flame retardant performance is better than that of ordinary plastics. However, in some occasions with high flame retardant requirements, furth...
