Abstract

The invention suitable for the field of engineering plastics provides a PC (polycarbonate) composite material as well as a preparation method and an application thereof. Aryl sulfone sulfonate of alkali metal or alkali-earth metal, a phosphate compound and a polysiloxane compound with reactive functional groups are used as flame retardants, so that the flame retardant property of the PC composite material is greatly improved, the infrared light transmittance of PC is not damaged, and the PC composite material is excellent in infrared transmittance and flame retardant property. The preparation method for the PC composite material is simple to operate and low in cost, and is very suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of engineering plastics, and in particular relates to a PC composite material, its preparation method and application. Background technique [0002] Infrared transmissive materials are widely used in infrared imaging and guidance technology because of their good infrared transparency and wide transmission band, such as lenses, prisms, windows, filters and other materials. Plastic is an amorphous polymer. Some plastics have good transmittance in the infrared or far infrared band, so they can be used to prepare infrared windows, lenses, etc. The most common infrared plastics include: acrylate and methacrylate plexiglass, polyethylene, polypropylene plastic, polytetrafluoroethylene, polytetramethylpentene plastic, etc.; plastics have been widely used in infrared alarm, Infrared monitoring and sensing and other civilian or police fields. [0003] Polycarbonate occupies an extremely important position in the optical fiel...
