Abstract
The invention relates to a UVC radiation-resistant polycarbonate composition as well as a preparation method and application thereof. The polycarbonate composition comprises polycarbonate, SAN, ASA rubber powder, a triazine UV absorbent, a benzotriazole weather-resistant agent, a hindered amine weather-resistant agent, toner, an antioxidant, a metal deactivator and other processing aids. The polycarbonate composition provided by the invention not only has higher UVA and UVB radiation resistance, but also has higher UVC radiation resistance, can effectively prevent aging and yellowing of materials, 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 polycarbonate composition resistant to UVC radiation, 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 wave band 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 pres...
