Embodiment 1
[0039] A Tetra Pak recycled PE / PLA wire for 3D printing, characterized in that:
[0040] (1) the weight percent formula is as follows:
[0041] Tetra Pak Recycled PE 70
[0042] PLA 27
[0043] PE-g-MAH 2
[0044] P990 0.5
[0045] White oil 0.5
[0046] (2) Preparation method:
[0047] A. Put Tetra Pak recycled PE and PLA in a vacuum drying oven to dry;
[0048] B. According to the formula by weight percentage, take by weighing the dried Tetra Pak to recycle PE, PLA, PE-g-MAH, P990 and white oil;
[0049] C. each component after weighing is placed in the high-speed kneader, keep rotating speed 2000 rpm, and stir at high speed for 20min;
[0050] D. Add the uniformly mixed Tetra Pak recycled PE, PLA, PE-g-MAH, P990, and white oil to the feeding port of the screw extruder. The temperature of the screw extruder is 150-210°C, and the speed is 70rpm; The extruded raw material is cooled and sent to the pelletizer to be cut into pellets, and dried for later use;
