The invention discloses a catalyst component for olefin polymerization and a preparation method and application thereof. The catalyst component is prepared by the following steps: (1) contacting a magnesium compound, an organic epoxy compound, an organic phosphorus compound and a silane compound in a solvent to obtain a uniform solution; (2) in the presence of a phenolic compound, contacting the obtained uniform solution with a titanium compound; (3) contacting the mixture obtained in the step (2) with an electron donor compound and filtering, washing and drying to obtain the titanium-containing catalyst component for olefin polymerization. The catalyst disclosed by the invention used for propylene polymerization and copolymerization has high catalyst activity and is slow in active attenuation. |
