| 摘 要： | 为探索聚丙烯(PP)/聚酯(PET)针刺过滤材料的耐热老化性能,采用烘箱法对试验制备的3种PP/PET针刺过滤材料样品进行不同热老化温度和热老化时间的处理,研究热老化温度和热老化时间对PP/PET针刺过滤材料各项性能的影响。结果表明:随着热老化时间的延长和热老化温度的升高,PP/PET针刺过滤材料的质量、厚度、断裂强度降低,尺寸缩小;当热老化温度超过120℃、热老化时间超过4.0 h后,热老化程度明显加剧。

| Abstract: | In order to explore the thermal aging property of the PP/PET needle filter material, three kinds of PP/PET needle filter material samples prepared by experiments were dealed with different thermal aging temperatures and times in the oven, and the effect of thermal aging temperature and time on the properties of PP/PET needle filter material was researched.The results showed that, with the thermal aging time extending and thermal aging temperature increasing, quality, thickness, tensile strength of the PP/PET needle filter material were reduced, and the size also was shorten;and when the thermal aging temperature exceeded 120 ℃and the thermal aging time exceeded 4 .0 h, the degree of thermal aging increased significantly. |
