摘要:
对中国石油独山子石化公司生产的锂电池隔膜专用料T 98 G与2种市售典型电容膜专用聚丙烯（PP）树脂进行了对比分析。结果表明：3种专用料均为均聚PP，力学性能相当；2种进口电容膜专用料的熔体流动速率较T 98 G低；T 98 G等规指数较进口料1高，略低于进口料2，灰分略高于2种进口料；与2种进口料相比，T 98 G的相对分子质量分布较窄，结晶及熔融起始温度最高，氧化诱导时间最均最长，3种专用料的氧化诱导时间均长于30 min；T 98 G的含铝、钙、硅等离子量，较2种进口料略高；3种样品所制薄膜拉伸力学性能相当，T 98 G落镖冲击略低。
Abstract:
Special material T 98 G for lithium battery diaphragm produced by Dushanzi Petrochemical Company， PetroChina， was compared with two imported polypropylene （PP） for capacitor film. The results showed that the three special materials were homopolymer PP with similar mechanical properties. The melt flow rate of the two imported capacitor film materials was lower than that of T 98 G. Isometric index of T 98 G was higher than that of imported material 1， and slightly lower than that of imported material 2. The ash content of T 98 G was slightly higher than that of two imported materials. Compared with the two imported materials， the molecular weight distribution of T 98 G was narrower， and the crystallization， initial melting temperature and oxidation induction time were the highest. The oxidation induction time of the three special materials was higher than 30 min. The plasma content of aluminum， calcium and silicon of T 98 G was slightly higher than that of the two imported materials. The tensile mechanical properties of the films produced by the three samples were similar， and the impact of T 98 G falling dart was slightly lower.
