Embodiment 1
[0014] Embodiment 1, a kind of method for reducing polyethylene melt flow velocity, its technological process is as follows:
[0015] A. Preparation of additives: Take 100 parts of polyethylene and 5-10 parts of polyethylene cross-linking agent for later use;
[0016] B. Mixing: Mix the above additives evenly at room temperature for later use;
[0017] C. Dilution: Dilute polyethylene by 100:1, that is, take 100 parts of polyethylene, put 1 part of the above-mentioned auxiliary agent into 100 parts of polyethylene, and stir evenly;
[0018] D. On the machine: Put the above-mentioned uniformly mixed mixture into the extruder to granulate, so that the polyethylene melt flow rate can be reduced.
Embodiment 2
[0019] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the polyethylene crosslinking agent is gem-diperoxy tert-butyl-3,3,5-trimethylcyclohexane.
Embodiment 3
[0020] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that the polyethylene crosslinking agent is 8 parts.
