摘要
研究了抗氧剂PEPQ对聚丙烯(PP)树脂的抗氧化性能,并与抗氧剂168进行了对比。结果表明,添加抗氧剂PEPQ的PP树脂具有良好的加工性能和热稳定性能,经5次反复挤出保持良好的力学性能,拉伸强度保持90%以上,黄色指数YID为0.96。
The anti-oxygenation properties of antioxidant PEPQ in polypropylene （ PP ） resin were studied and compared with antioxidant 168. Results show that the added antioxidants PEPQ has excellent processability and thermal stability,excellent mechanical properties of 5 times repeated extrusion,tensile strength was above 90%and the YID was 0. 96.
