【摘要】 研究了采用氧化淀粉作为成炭剂,与密胺树脂包覆的聚磷酸铵复配后制备阻燃环氧树脂。结果表明,采用6.25%OST3和6.25%MFAPP复配的膨胀型阻燃剂制备的阻燃环氧树脂的阻燃性能最好,所制备阻燃环氧树脂的LOI为29.5%,能通过UL-94V-0级,热释放速率峰值为400kW/m2,总热释放量为13.4MJ/m2,点燃时间最短,仅为22s。更多还原

【Abstract】 Oxidized starch as charring agents and MFAPP were used to prepared flame retard epoxy resin.Results showed that the flame retardancy was the best when the additives were contained 6.25wt% OST3 and 6.25wt% MFAPP.The test results of LOI,UL-94,PHRR,THR and TTI were 29.5%,V-0,400kW/m2,13.4MJ/m2,22 s,respectively.更多还原
