Abstract
The invention discloses a self-cleaning polyethylene thin film and a method for preparing the same. The self-cleaning polyethylene thin film comprises a modified microcrystallinewax film layer, a zincferrite layer, a first conductive polyethylene thin film layer, a cobaltoxide layer and a second conductive polyethylene thin film layer which are sequentially connected with one another. The self-cleaning polyethylene thin film comprises modified microcrystallinewax films, zinc ferrite, cobaltoxide and conductive polyethylene thin films, and a mass ratio of the modified microcrystallinewax films to the zinc ferrite to the cobaltoxide to the conductive polyethylene thin films is 1:12-19:1-8:49-76. The self-cleaning polyethylene thin film and the method have the advantages that the self-cleaning polyethylene thin film is prepared from the modified microcrystalline wax films, the zinc ferrite, the cobalt oxide and the conductive polyethylene thin films, polyethylene thin films are prepared by the aid of pressure fitting processes, and self-cleaning polyethylene thin film materials prepared by the aid of the method are excellent in self-cleaning property and mechanical property.
Description
technical field [0001] The invention relates to a self-cleaning polyethylene film and a preparation method thereof, belonging to the field of self-cleaning films. Background technique [0002] Polyethylene film is a translucent, shiny, soft texture, with excellent chemical stability and water resistance, and is resistant to freezing and boiling. It is mainly used for the inner film of composite flexible packaging materials and agricultural films. [0003] At present, polyethylene films need to be further improved in terms of self-cleaning and mechanical properties. Contents of the invention [0004] In order to solve the problem that the self-cleaning and mechanical properties of polyethylene films need to be further improved in the prior art, the present invention provides a self-cleaning polyethylene film and a preparation method thereof. [0005] In order to solve the problems of the technologies described above, the technical scheme adopted in the present invention is...
