WIPO Patent Application WO/2020/108217
Kind Code:
A1
Abstract:
Disclosed is a flame-retardant HIPS material and a preparation method thereof. The flame-retardant HIPS material comprises the following components: 90-67 parts of HIPS resin, 8-15 parts of bromine flame retardant and 3-7 parts of auxiliary flame retardant. The auxiliary flame retardant is a 1,3,5-triazine compound. In the present invention, the combined use of a bromine flame retardant and an auxiliary flame retardant effectively reduces the amount of the bromine flame retardant and can reach a stable UL94 (1.5 mm) V-0 flame retardant grade. Compared with te existing bromine flame-retardant HIPS, the flame-retardant HIPS material has a low halogen content, low gas and high cost performance, avoids excessive acidic gas and the formation of air lines on the surface of parts, provides a good appearance, and can be widely used in thin-walled parts such as office equipment, television multimedia, household appliances, etc.
