| 摘 要： | 以碱式硼酸镁(MBH)和环氧树脂(EP)为原料,制备EP/MBH复合材料。采用紫外可见分光光度计,同步热分析仪(TG),极限氧指数仪(LOI)和锥形量热仪(CCT)等研究了EP/MBH复合材料的光学透过率、热稳定性和火安全性能。结果表明,1 wt%～10 wt%MBH与EP基体可制得透光性能良好的EP/MBH阻燃复合材料。其中,800～400 nm波长范围内,MBH质量分数为10 wt%的复合材料光学透过率依然超过70%;EP/5MBH复合材料达难燃级别,热释放速率峰值(pHRR)、烟释放速率峰值(pSPR)、CO释放速率峰值(pCOP)、CO_2释放速率峰值(pCO_2P)以及火灾蔓延指数(FIGRA)分别降低38%、30%、50%、35%和41%。研究结果表明,MBH可明显提高环氧树脂复合材料在绿色能源及航空航天等领域的应用价值,为制备透明阻燃复合材料提供了一种新思路。

| Abstract: | EP/MBH composites were prepared by using basic magnesium borate (MBH) and epoxy resin (EP).Transmittance,thermal stability and flame retardancy of EP/MBH composites were investigated by UV-visible spectrophotometer,synchronous thermal analyzer (TG),limiting oxygen index (LOI),cone calorimeter (CCT) and other testing methods.The results showed that 1 wt%~10 wt% MBH and EP matrix can produce EP/MBH composites with excellent transmission performance and flame retardancy.The transmittance of EP/MBH composites with the addition of 10 wt% was up to 70% in the wavelength range of 800~400 nm.EP/5MBH composites reached a flame retardant level,and the peak of heat release rate (pHRR),the peak of smoke release rate (pSPR),the peak of CO release rate (pCOP),the peak of CO2 release rate (pCO2P),and fire spread index (FIGRA) decreased by 38%,30%,50%,35%,and 41%,respectively.MBH can significantly improve the application value of epoxy resin composite materials in the fields of green energy and aerospace,and provided a new idea for the preparation of transparent flame retardant composites. |
