添加不同种类、不同数量的纳米蒙脱土,混炼制得HIPS/纳米蒙脱土复合材料,以改善高抗冲聚苯乙烯(HPS)的性能,测试了其力学性能、热稳定性及阻燃性。结果表明,添加3％烘干的蒙脱土Cloisite 30A的HIPS/纳米蒙脱土复合材料具有较好的综合力学性能,可作为工程塑料使用;HIPS/纳米蒙脱土复合材料的热稳定性与阻燃性有所改善,添加5％烘干的蒙脱土Cloisite 15A的 HIPS/纳米蒙脱土复合材料具有较好的阻燃性。
Adding different types and amounts of nano-montmorillonite and mixing them to prepare HIPS / nano-montmorillonite composite to improve the performance of high-impact polystyrene (HPS), testing its mechanical properties, thermal stability and resistance Flammability. The results showed that HIPS / nano-montmorillonite composites with 3% montmorillonite Cloisite 30A had good mechanical properties and could be used as engineering plastics. The thermal stability of HIPS / nano-montmorillonite composite with The flame retardance was improved. HIPS / nano-montmorillonite composite with 5% montmorillonite Cloisite 15A had better flame retardancy.
