Provided are a flame-retardant polyamide glass fiber composition and a preparation method therefor. The flame-retardant polyamide glass fiber composition comprises, in parts by weight: 40-65 parts of a polyamide resin, 25-40 parts of glass fibers, 0-20 parts of a flame retardant, 0.2-1 part of an antioxidant, and 0.1-2 parts of other auxiliaries. The flame-retardant polyamide glass fiber composition provided in the present invention not only has a bio-based source, but also has a flame retardance of V-0 in UL94 and excellent mechanical properties, and can be widely applied to the fields of various engineering plastics with high requirements for flame retardant effect and dimensional stability. |
