| description | The invention discloses a preparation method and application of a high-tensile-strength polypropylene film, and relates to the technical field of high polymer material processing. The invention belongs to a high-tensile-strength polypropylene film for a lithium battery composite current collector. According to the preparation method of the high-tensile-strength polypropylene film, temperature parameters of all sections in a production line are set, main factors influencing crystallization, stretching orientation and shaping processes of polypropylene molecules are trivially controlled, and it is guaranteed that the product performance suitable for a composite current collector is obtained; in the processing process, high-temperature resin is selected as a raw material, and various properties of the film are controlled at a temperature and a draw ratio suitable for processing, so that the high-tensile-strength polypropylene film is produced.
