摘　　要：以超支化聚酯(HBPE)与γ-氨丙基三乙氧基硅烷(KH550)为原料制备了一种含硅、氮的新型阻燃剂(K-HBPE)。傅里叶红外光谱(FT-IR)和扫描电子显微镜(SEM)结果证明其已成功制备,然后将其与聚磷酸铵(APP)复配添加入聚丙烯(PP)中。在30%(K-HBPE∶APP=1∶1)的添加质量下,阻燃PP的极限氧指数(LOI)增加到了33.2%,且成功通过了UL-94的V-0级别。实验表明K-HBPE与APP有优异的协同阻燃效应。A novel flame retardant(K-HBPE)containing silicon and nitrogen was prepared from hyperbranched polyester(HBPE)andγ-aminopropyltriethoxysilane(KH550).FT-IR and SEM confirmed the synthesis of K-HBPE,which was then blended with ammonium polyphosphate(APP)into polypropylene(PP).With 30%(K-HBPE∶APP=1∶1)of the intumescent flame retardant,the limiting oxygen index(LOI)of PP composite was increased to 33.2% and the UL-94 test achieved V-0 rating.The results showed that K-HBPE with APP had an excellent synergistic flame retardant effect.
