Abstract
The invention discloses a flame-retardant polyamide composite material and a method for preparing the flame-retardant polyamide composite material. The flame-retardant polyamide composite material is characterized by comprising 40-80wt% (weight percent) of polyamide resin, 0-30wt% of reinforcing material, 10-25wt% of flame retardant, 2-4wt% of synergistic flame retardant, 2-5wt% of compatibilizer, 0.5-1wt% of heat stabilizer and 0.5-1wt% of processing aid. The method for preparing the flame-retardant polyamide composite material comprises the following steps: adding the polyamide resin, the reinforcing material, the flame retardant, the synergistic flame retardant, the compatibilizer, the heat stabilizer and the processing aid into a twin-screw extruder, melting, mixing, extruding and granulating. The flame-retardant polyamide composite material disclosed by the invention has stable thermal stability and flame-retardant effect, good comprehensive mechanical performance and processing and forming performance and wider application range and field and can be applied to the fields of automotive industry, electronic industry and furniture industry.
