氧化石墨烯与Si-P低聚物在环氧树脂中的协同阻燃作用
DOI: 10.11777/j.issn1000-3304.2015.14302, PP. 382-389
Keywords: 氧化石墨烯,协同阻燃,环氧树脂,锥型量热
Abstract:
采用Hummers方法制备了氧化石墨烯(GO),并通过扫描电镜(SEM)和原子力显微镜(AFM)对GO微观形貌进行了表征.详细研究了GO与硅磷低聚物(DMS-DOPO)在环氧树脂(EP)力学性能和阻燃性能中的协同作用.万能材料试验测试结果表明,GO和DMS-DOPO分别对拉伸强度和断裂伸长率提高效果明显,二者协同后,可使EP拉伸强度和断裂伸长率分别提高17.1%和42.2%.采用热重分析(TG)、极限氧指数(LOI)、垂直燃烧(UL-94)、锥型量热(CONE)和SEM对EP及其阻燃材料的热性能、燃烧性能以及炭层微观形貌进行了表征.EP/DMS-DOPO/GO在600℃残留量为EP的5.2倍,比EP/DMS-DOPO和EP/GO分别提高4.4%和208.6%.EP/DMS-DOPO/GO的LOI值大于30,并能通过UL-94V-0级别,燃烧过程中可形成内部结构疏松多孔、外表面致密的膨胀炭层.DMS-DOPO和GO协同后使EP热释放速率峰值由1154kW·m-2降低到710kW·m-2,总烟释放量降低30%.
