Problems solved by technology

[0003] However, the long-term thermal aging resistance of existing PC composite materials is generally poor, which limits its application in many fields
CN 106674962A discloses a PC / ABS alloy with excellent heat aging performance and its preparation method. After the PC / ABS alloy is subjected to 1000h heat aging at 100°C, its notched impact strength retention rate can reach 56% to 76%. Good long-term thermal aging resistance, but the aging temperature of 100°C is still low, which still cannot meet the actual application requirements well

Abstract

The invention discloses a halogen-free and flame-retardant PC material capable of resisting long-term heat aging, and a preparation method thereof. The halogen-free and flame-retardant PC material comprises PC resin, silicon copolymerized PC, flame-retardant master batches, a stabilizer, an anti-dripping agent, a main antioxidant, an auxiliary antioxidant, a lubricant and an ultraviolet absorber.The preparation method is very simple; and all the components are thoroughly uniformly mixed, and then the obtained mixture is added into a twin-screw extruder, and is extruded and granulated. The halogen-free and flame-retardant PC material has an excellent flame retardant performance and excellent long-term heat aging resistance, and the preparation method has the advantages of simplicity, low production cost, and easiness in industrial production.

Description

technical field [0001] The invention belongs to the technical field of PC composite materials, in particular to a halogen-free flame-retardant PC material resistant to long-term thermal aging and a preparation method thereof. Background technique [0002] PC resin, that is, polycarbonate resin, not only has excellent mechanical properties, electrical properties, transparency, and dimensional stability, but also has good heat resistance (glass transition temperature 150 ° C, heat distortion temperature 135 ° C) . Therefore, PC resin is widely used in home appliances, charger casings or other electronic and electrical accessories. [0003] However, the long-term thermal aging resistance of existing PC composite materials is generally poor, which limits its application in many fields. CN 106674962A discloses a PC / ABS alloy with excellent heat aging performance and its preparation method. After the PC / ABS alloy is subjected to 1000h heat aging at 100°C, its notched impact stre...
