| titleOfInvention | A kind of photodegradable PE stretch film and preparation method thereof |
| abstract | A photodegradable PE stretch film and a preparation method thereof, the stretch film comprises the following components: 100 parts of modified linear low density polyethylene (LLDPE), 3-5 parts of tackifier, modified LLDPE consists of ethylene, 1-butene , 1‑hexene and ketone-containing monomers with alkenyl groups are copolymerized. The invention prepares the modified LLDPE by adding a ketone-containing comonomer in the preparation process of the linear low-density polyethylene, and the photodegradable PE winding film prepared with the modified LLDPE can degrade automatically under sunlight irradiation after use. In the present invention, by adjusting the dosage and ratio of diacetone acrylamide and methyl vinyl ketone and/or ethyl vinyl ketone, it not only has the effect of synergistically improving the elongation at break of the PE stretch film, but also improves the tensile strength of the PE stretch film. Self-adhesive, reduce the amount of adhesive appropriately. The addition of antistatic agent alkoxyamine salts in the preparation process of linear low density polyethylene not only improves the antistatic performance of the material, but an appropriate amount of alkoxyamine salts helps to further improve the photodegradation performance of the material. |
