摘要

摘要

En 中文
欧盟对卤化阻燃剂的规定促使了对替代品的调查。聚对苯二甲酸丁二醇酯(PBT)因其应用于电气和电子产品方面的优良性能而广泛应用,是这些指南下存在风险的一种聚合物。实际上,其较差的阻燃性常常限制其使用或需要添加潜在有毒元素。因此,改善其阻燃性能至关重要,而固态改性(SSM)是理想的方法,可在保持其结晶结构和热机械特性的同时实现这一点。因此,采用生物基共单体通过SSM制备了一种膨胀共聚酯。首先,用碳化剂2,3:4,5-di-O-异亚丙基-半乳糖醛酸酯(GalX)改性PBT。该过程的优化涉及对温度、时间和压力影响的研究。P(BT-co-GalXT)的热性能表明,PBT的优良性能得以保留,反映了固态反应过程中结晶相的保持。最后,纯PBT可与共聚酯和聚磷酸铵组合,得到一种膨胀系统,在UL 94测试中表现出V-0等级。该组分既保留了均聚物的理想性能,又改善了阻燃行为。
