摘要

通过聚磷酸铵(APP,n=200)的铵根离子(NH⁺₄)和3-氨基丙基三乙氧基硅烷(APTES)的氨基(—NH₂)发生阳离子交换反应,制备了一种含磷/氮/硅的新型阻燃剂(APTES-APP)。傅里叶红外光谱、X射线光电子谱、扫描电子显微镜和热重分析结果证明其已成功制备,然后将其与聚磷酸铵(APP,n>1000)复配添加于环氧树脂(EP)中。10%(APP∶APTES-APP=4∶1)的添加量即可使阻燃EP的极限氧指数增加到26%,且通过了垂直燃烧测试的V-0级。

Abstract

A new flame retardant (APTES-APP) containing phosphorus(P)/nitrogen(N)/silicon(Si) was prepared by cation exchange reaction between the ammonium ion (NH⁺₄) of ammonium polyphosphate (APP,n=200) and the amino group (—NH₂) of 3-aminopropyltriethoxysilane (APTES).FT-IR,XPS,SEM and TG demonstrated that APTES-APP flame retardant was successfully prepared,and then added to epoxy resin (EP) with ammonium polyphosphate (APP,n>1000).10wt% (APP∶APTES-APP=4∶1) of dosage increased the limiting oxygen index (LOI) of the EP composite to 26 vol%,and passed the V-0 rating of vertical burning test (UL-94).
