Abstract

The invention discloses a high-toughness and high-transparency organic silicon flame-retardant polycarbonate material and a preparation method thereof. The material comprises the following raw materials in parts by weight: 90-99 parts of polycarbonate, 0.05-3 parts of an organic silicon flame retardant, 0-0.5 part of an anti-dripping agent, 0.1-1 part of a dispersing agent and 0.1-0.5 part of an antioxidant. The polycarbonate is composed of polycarbonate resin powder and polycarbonate resin particles. The polycarbonate material prepared by the invention has the advantages of high toughness, high transparency, no halogen, environment friendliness, flame retardancy, favorable flame retardant dispersity and stable flame retardancy, and can satisfy the market demands for all-transparent flame-retardant products.

Description

technical field [0001] The invention relates to the technical field of halogen-free flame-retardant polycarbonate, in particular to a high-toughness and high-transparency organosilicon flame-retardant polycarbonate material and a preparation method thereof. Background technique [0002] Polycarbonate (PC) has excellent impact performance and good processing performance due to its rigid benzene ring and flexible isopropyl group and carbonate group. The benzene ring structure in polycarbonate makes the PC molecular chain have greater steric hindrance during the crystallization process, and the crystallinity of the material deteriorates. The special structural combination makes PC have extremely high light transmittance (90%) and extremely Low haze (2%). High light transmittance endows PC with a special field of use. However, with the improvement of human requirements for materials, the flame retardancy of PC materials cannot meet the needs of use in more and more environments...
