Abstract

The invention discloses a flame-retardant polycarbonate composite material, which comprises the following components in parts by weight: 70-90 parts of carbonate resin; 3-13 parts of flame retardant; 0.5-15 parts of flame retardant synergist; 0.2-1.5 parts of anti-drip agent; the flame retardant synergist is compounded by iron red and iron yellow, and the weight ratio of iron red and iron yellow is between 8:1-1:8. By using iron red and / or iron yellow as a flame retardant synergist, a dense network structure is formed under the synergistic effect of the anti-dripping agent, which effectively improves the surface smoothness and density of the formed carbon layer and makes its oxygen index increased and improved the mechanical properties of polycarbonate composites.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a flame retardant polycarbonate composite material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is a high molecular polymer containing carbonate groups in its molecular chain. It is a thermoplastic engineering plastic with excellent comprehensive properties. It has outstanding impact resistance, weather resistance, impact resistance and electrical insulation. High light transmittance and flame retardancy (flame retardant rating is UL94 V-2). However, polycarbonate is still combustible, and hot melt drips during burning, which easily causes nearby materials to catch fire, making it difficult to meet the requirements of flame retardant and fire protection. Therefore, flame retardant treatment of PC is required in practical applications. [0003] The halogen-free flame retardant PC is used in the field of communication appliances and...
