  The present invention relates to the technical field of catalyst preparation, and discloses a preparation method of a Ziegler-Natta catalyst. The method includes the following steps: subjecting magnesium halide, alcohol and an electron donor to a first contact reaction in the presence of an inert solvent to obtain a magnesium halide alcoholate and performing first cooling; subjecting titanium halide to second cooling; subjecting the cooled titanium halide, the cooled product containing the magnesium halide alcoholate and an electron donor to a second contact reaction; filtering the product of the second contact reaction to obtain the Ziegler-Natta catalyst; and subjecting the Ziegler-Natta catalyst and the heated titanium halide to a third contact reaction. The method has the advantages such as short cycle, high efficiency, etc., being suitable to industrial production.

  Provided in the present invention is a solid catalyst component for use in olefin polymerisation, comprising Mg, Ti, a halogen, and at least one electron donor, the electron donor being a 2-substituted amino-phenyl ester compound selected from general formula (I). Also disclosed in the present invention are a catalyst comprising the solid catalyst component, and an application for the catalyst in olefin polymerisation, particularly in propylene polymerization. Also provided in the present invention is a high activity catalyst, said catalyst being able to obtain polypropylene of high isotacticity and wide molecular weight distribution, and not requiring an external electron donor to obtain high isotacticity polypropylene; during polymerization, Al/Ti and Al/Si are reduced, the polymerization time is lengthened, and high activity can still be maintained, suitable for producing low-ash polymers.
