硅烷改性氮化碳协同聚磷酸铵对环氧树脂阻燃与抑烟性能的影响
Effects of silane-modified carbon nitride synergized with ammonium polyphosphate on flame retardancy and smoke suppression of epoxy resins
摘要
Abstract
Silane-modified carbon nitride(CN-KH560)was prepared by coating carbon nitride nanosheets(CNNS)with a hydrophilic layer formed from γ-glycidyloxypropyltrimethoxysilane(KH560)and polydopamine.This modified filler was incorporated into epoxy resin(EP)in combination with ammonium polyphosphate(APP)at optimized ratios to fab-ricate flame-retardant EP composites.The resulting materials were evaluated for their flame retardancy,smoke suppres-sion,and mechanical properties.The results show that when 9 wt%APP and 1 wt%CN-KH560 were added,the EP/9 APP/1CN-KH560 composite achieved a UL 94 V-0 rating in the vertical burning test and exhibited a limiting oxygen in-dex of 40.2%.Compared with neat EP,the composite reduced total heat release and total smoke production by 48.76%and 53.5%,respectively.Moreover,the EP/9APP/1CN-KH560 composite retained the excellent mechani-cal properties of the base epoxy resin.关键词
