Description

technical field

[0001] The present invention relates to a catalyst component for ethylene polymerization, a preparation method of the catalyst component and a catalyst thereof. More particularly, it relates to a catalyst component for ethylene polymerization containing two electron donors, a method for preparing the catalyst component and a catalyst thereof. Background technique

[0002] The Ziegler-Natta type ethylene polymerization spherical catalyst prepared by using magnesium chloride ethanol carrier has been industrialized for many years, but due to the limitation of insufficient catalyst activity, this type of catalyst is mainly used in the gas phase polymerization process. If the activity of this type of catalyst can be improved so that it can be applied to the slurry polymerization process, spherical polyethylene pellets that are similar in shape to the catalyst, have good fluidity and bulk density, and do not need to be pelletized can be obtained.
