摘要
通过三乙氧基硅氢改性纤维素合成了一种硅烷改性纤维素材料(SOCL),通过FT-IR、SEM、TG对其进行结构和热性能分析;并把SOCL做碳源与聚磷酸铵(APP)复配成膨胀型阻燃剂(IFR),用于阻燃聚丙烯(PP)。结果表明:硅烷改性纤维素能很好地提高纤维素的热稳定性;与APP复配能有效提高PP的阻燃性。
A kind of silane-modified cellulose material （SOCL） was successfully synthesized through modifying cellulose by triethoxysilane compound. The structure and thermal properties of SOCL were analyzed by FT-IR, SEM and TG; SOCL was used as carbon source to form an intumescent flame retardant （IFR） with the presence of ammonium polyphosphate （APP） for polypropylene （PP）. The results show that the thermal stability of cellulose improves by adding the silane, and the flame retardant properties of PP obviously improves with the addition of SOCL/APP.
