| description | The invention discloses an antibacterial heat-shrinkable tube which comprises the following components in parts by weight: 1-30 parts of modified dopamine; 100 parts of polyethylene; 10 to 50 parts of EVA; 10 to 30 parts of POE (Polyolefin Elastomer); 1 to 10 parts of an antioxidant; wherein the modified dopamine is enoyl chloride modified dopamine. The invention also provides a preparation method of the antibacterial heat-shrinkable tube, which comprises the following steps: S1, modification of dopamine: taking dopamine and an acid-binding agent, pouring into an organic solvent, stirring, dropwise adding an enoyl chloride reagent under the protection of nitrogen, reacting, filtering precipitate after the reaction is finished, and evaporating the organic solvent to obtain modified dopamine; s2, preparation of the antibacterial heat-shrinkable tube: taking the modified dopamine, adding polyethylene, EVA, POE and an antioxidant, mixing and granulating, extruding a hollow tube, performing irradiation crosslinkin |
