软性PVC基隔音复合材料的阻燃性研究

On the Flame-Retardant Properties of Soft PVC-Base Composite Insulation

探讨软性PVC基隔音复合材料阻燃及其发烟与材料成分之间的关系。在保证不降低其隔音性能的前提下,添加不同阻燃剂以及其复合配方提高其材料的阻燃和抑烟性能。使用DMA、混响室-静音箱测试系统、TG-DTG、以及极限氧指数仪进行相关指标的测试。结果显示:阻燃剂的添加基本不影响复合材料的隔音性能,但能较好地提高复合材料的阻燃和抑烟性能,此隔音复合材料在隔音领域可提供消防安全保障。

This paper discusses the relationship between the flame-retardant and smoke suppression properties of soft PVC-base composite insulation and the formulas of material composition.Not reducing the acoustic insulation property,the authors add different flame retardants and their complex formulas to improve the flame-retardant and smoke suppression properties of materials,using DMA,reverberation-anechoic chambers measuring system,TG-DTG,and limiting oxygen index test related indicators.The results show that the addition of flame retardants composite material does not influence the acoustic insulation property,but it is able to improve the flame-retardant and smoke suppression properties of material,for providing fire safety in the field of the acoustic insulation.
