Title:
FLAME-RETARDANT HIGH-IMPACT POLYSTYRENE COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/238146
Kind Code:
A1
Abstract:
A flame-retardant high-impact polystyrene composite material and a preparation method therefor, the following components thereof and the parts by mass of each component being: 85 parts of high-impact polystyrene, 3-15 parts of a modified phosphorus-based flame retardant and 3-15 parts of a nano flame retardant, wherein the modified phosphorus-based flame retardant is a silane coupling agent modified phosphorus-based flame retardant, and the mass ratio of the silane coupling agent to the phosphorus-based flame retardant is (2-7):100. The phosphorus-containing flame retardant and the nano flame retardant have a synergistic effect in terms of flame retardant effect, so that the flame retardant property of the composite flame retardant may be improved, and the flame retardant property of the high-impact polystyrene composite material is enhanced. The present invention has a simple process flow, has extensive raw material sources, is non-toxic and harmless, is environment-friendly, and has good application prospects.
