Embodiment 1
[0058] Embodiment 1 Preparation of elemental masterbatch
[0059] This example provides an element masterbatch, in parts by mass, including 66.01 parts of polyethylene terephthalate, 2.49 parts of zinc oxide (2 parts of zinc element content), 4.05 parts of zirconium dioxide (3 parts of zirconium element content parts), 9.45 parts of aluminum oxide (5 parts of aluminum element content), 8 parts of polyethylene wax, 5 parts of antioxidant, and 5 parts of coupling agent; wherein zinc element content: zirconium element content: aluminum element content = 2: 3:5;
[0060] The preparation method is as follows: (1) Weigh each component in the elemental masterbatch according to the formula amount; use a mill to make the weighed polyethylene terephthalate into a powder with an average particle size of 350±30nm ;
[0061] (2) Mix the components weighed in step (1) and put them into a screw extruder for extrusion. The extrusion temperature is 280±5°C and the screw speed is 300r / min;
