摘要
随着绿色化学概念的提出,在全世界范围内形成了离子液体的研究热潮。离子液体具备非挥发性或"零"蒸气压;低熔点;宽液程;高热稳定性;酸碱可调性;可循环使用性;非燃性等优良特性,使离子液体被公认为是符合绿色化学理念的溶剂与材料。聚碳酸酯(PC)作为重要的工程塑料,很多应用对其有阻燃性能有较高要求。而传统用于PC的阻燃剂不具备很好的环境友好性。
Ionic liquids have good properties,especially their environmental-friendly properties accord with the concept of green chemistry.In this article,a halogenfree imidazole ionic liquid OTM was used as a flame retardant for polycarbonate(PC),and a series of PC/OTM compounds were prepared.By means of the measurement of LOI,UL-94 test,TGA,MFI and SEM,the effect of the ionic liquid on flame retardancy,thermal degradation and char yield of PC were investigated.The results showed that,after the addition of 0.1phr OT...
