Toughened high impact polystyrene composition and preparation method thereof

The invention belongs to the field of new materials, and particularly relates to a toughened high-impact polystyrene composition and a preparation method thereof. The toughened high-impact polystyrene composition is characterized by being prepared from the following components in parts by weight through melt blending: 10 to 60 parts of polyphenyl ether (PPO) resin, 30 to 60 parts of high-impact polystyrene (HIPS) resin, 0 to 10 parts of styrene-butadiene-styrene block copolymer (SBS), 2 to 10 parts of modifier, 0 to 15 parts of functional nano filler and 1 to 5 parts of silane coupling agent. According to the material, the special modifier and the functional nano filler are selected to be subjected to high-temperature melt blending modification with various resins, so that the processability, such as toughness, of the composite material is greatly improved. 本发明属于新材料领域，特别涉及一种增韧高抗冲聚苯乙烯组合物及其制备方法。一种增韧高抗冲聚苯乙烯组合物，其特征在于该组合物是由以重量份计的如下组分熔融共混制得：聚苯醚(PPO)树脂10-60份，高抗冲聚苯乙烯(HIPS)树脂30-60份，苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)0-10份，改性剂2-10份，
