| titleOfInvention | Preparation method of catalyst component for ethylene polymerization reaction and catalyst thereof |
| abstract | The invention relates to a preparation method of a catalyst component for ethylene polymerization or copolymerization and a catalyst thereof. The method comprises the steps of: (1) at a temperature of 50-90DEG, dissolving magnesium halide in a solvent system containing an organic epoxy compound and an organic phosphorus compound to form a uniform solution; adding an organic alcohol compound during or after the solution formation and leaving them to react for certain time so as to obtain a reaction solution; (2) in the presence of a boron compound and at a temperature of -30DEG C-0DEG C, subjecting the solution and a titanium compound to a contact reaction, or adding the boron compound after the contact reaction of the solution obtained in step (1) and the titanium compound, and raising the temperature of the mixture slowly to 50-120DEG C, leaving solids to precipitate gradually and form particles, after certain period of reaction, removing the unreacted material and the solvent, and conducting washing with an inert diluent so as to obtain a solid component; and (3) suspending the solid component in certain amount of the inert diluent, performing a contact reaction with an organic aluminium compound under a temperature of 0DEG C-50DEG C, and after certain reaction time, removing the inert diluent, thus obtaining the catalyst component. The catalyst provided in the invention has high catalytic activity and good hydrogen response. |
