This invention relates to the field of catalyst synthesis technology, and more particularly to an alkoxytitanium non-metallocene catalyst for preparing polyethylene wax and its preparation method. The alkoxytitanium catalyst prepared by this invention can directly carry out ethylene polymerization. The polymerization process is simple, requires only a small amount of alkyl aluminum halides for impurity removal, and exhibits high catalytic activity. It requires no additional organoboron compounds or methylchlorooxyalkane, nor does it require chain transfer agents to adjust molecular weight. It has a novel structure, outstanding catalytic activity, and a simple synthesis process with diverse ligand designs. By designing different types of ligands, the molecular weight and activity of the polymer can be effectively improved, achieving precise control over catalyst activity and selectivity, thereby obtaining olefin polymers with specific structures and properties. This characteristic provides broad prospects for the preparation of polymer materials with specific properties and applications.
