摘　　要：为提高聚丙烯材料在煤矿中的安全等级及应用范围,采用微胶囊法设计合成一种具有阻燃及抗静电双功能助剂壳聚糖@聚磷酸铵@石墨微片(CS@APP@GM),通过FTIR、XPS、XRD、SEM和TEM等表征方法,研究了CS@APP@GM的化学组成及微观形貌,利用TG-IR、SEM、FTIR研究CS@APP@GM/PP复合材料的气相裂解产物及凝聚相残留物,揭示CS@APP@GM在聚丙烯中的阻燃机理。结果表明,将CS@APP@GM引入到聚丙烯材料中,在添加量为25%时,复合材料的阻燃性、抗静电性均得到显著提高。CS@APP@GM通过凝聚相阻燃机制和气相阻燃机制提高了聚丙烯复合材料的阻燃性能。This paper aims to improve the safety grade and application range of polypropylene in coal mine.The study consists of synthesizing CS@APP@GM with distinguished flame retardancy and antistatic property by the microcapsule method,employing FTIR,XPS,XRD,SEM and TEM to research the chemical composition and microstructure of CS@APP@GM,using TG-IR,SEM,and FTIR to investigate the gas phase cracking product and condensed phase residues,and revealing the flame-retardant mechanism of CS@APP@GM/PP composite in polypropylene.The result shows that by introducing CS@APP@GM into PP material at 25%,the flame retardancy and antistatic property of CS@APP@GM/PP composite is drastically increased.CS@APP@GM improves the flame retardancy of PP by condensed phase flame retardant mechanism and gas phase mechanism.
