The invention discloses a flame-retardant HIPS material and a preparation method thereof, comprising the following components: 79-91 parts of HIPS resin; 2-8 parts of brominated flame retardant; 3-7 parts of auxiliary flame retardant; The flame retardant is a 1,3,5-triazine compound. The invention effectively reduces the dosage of brominated flame retardants through the synergistic compounding of brominated flame retardants and auxiliary flame retardants, and can achieve a stable UL 94 (1.5mm) V-2 flame retardant grade; Compared with brominated flame retardant HIPS, it has low halogen content, low gas gas, high cost performance, better thermal stability, and less corrosiveness to molds. It can be widely used in the field of thin-walled parts, such as office equipment, film and television. Multimedia, household appliances, etc. |
