Abstract: Plastic Plant of PetroChina Daqing Petrochemical Company has developed and manufactured metallocene linear polyethylene resin 18X10D, with an aim to change China's total dependence on metallocene import, fill in the blank of no industrialized metallocene manufacturing, and promote China's plastics processing industry. This paper introduces the resin from such perspectives as process conditions and physical indexes, and finds that it has excellent processability and mechanical properties. It is proved that the 2m- and 9m- films made from metallocene resin feature in high quality, meet GB4455_2006 quality standard and consumers' requirements, and could be a substitute for imported ones.

Key words: LLDPE, metallocene, resin, development, application

摘要： 为改变当前我国茂金属产品几乎全部依赖进口的现状,填补国内没有工业化生产茂金属产品的空白,带动我国塑料加工行业的发展,中国石油大庆石化公司塑料厂在线性装置上开发生产出了茂金属聚乙烯树脂18X10D。文章从生产工艺条件、物性指标等方面进行了介绍,该树脂具有优异的加工性和力学性能。用茂金属树脂生产的2m、9m两种棚膜,产品质量好,满足GB4455-2006和用户标准要求,可替代进口茂金属产品。
