Abstract

The invention relates to a flame-retardant polycarbonate composition and a preparation method and application thereof. The flame-retardant polycarbonate composition comprises polycarbonate, SAN, ASA rubber powder, a phosphazene flame retardant, a triazine UV absorbent, a benzotriazole weather-resistant agent, a hindered amine weather-resistant agent, an anti-dripping agent, toner, an antioxidant, a metal deactivator and other processing aids. The polycarbonate composition provided by the invention not only has better UVA and UVB radiation resistance, but also has better UVC radiation resistance so that the aging and yellowing of materials can be effectively prevented; and the flame-retardant polycarbonate composition has good flame retardant property and can be widely applied to ultraviolet sterilization products.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and in particular relates to a flame-retardant polycarbonate composition and a preparation method and application thereof. Background technique [0002] Ultraviolet rays are divided into short-wave UVC (200-280nm), medium-wave UVB (280-320nm) and long-wave UVA (320-400nm) according to their wavelength. At present, some ultraviolet sterilizing equipment mainly use ultraviolet rays with a wavelength of 250-280nm to achieve sterilization and disinfection. However, the ultraviolet rays in this band have short wavelengths, strong energy, and very strong destructive power to equipment, so higher requirements are put forward for the resistance of equipment materials to ultraviolet radiation, especially UVC radiation. Polycarbonate and its alloys are widely used in ultraviolet disinfection equipment such as outdoor and kitchen and bathroom due to their excellent performance. At present, po...
