Embodiment 1
[0022] A geotechnical material, its composition in parts by weight is: 5-20 parts of A-random polypropylene, 80-90 parts of B, 10-30 parts of C, and 2-10 parts of D-color masterbatch. B is glass fiber modified polypropylene or carbon fiber modified polypropylene, and C is low pressure polyethylene. In the glass fiber modified polypropylene, the glass fiber is 10-30%, and the carbon fiber in the carbon fiber modified polypropylene is 10-30%. The preparation method is as follows:
[0023] (1) Add D to A, mix well, and put it into the A extruder for kneading and plasticizing; B is put into the hopper of the B extruder for kneading and plasticizing; C is put into the hopper of the C extruder for kneading and plasticizing Extrusion; extrusion processing temperature is controlled at 160-280°C;
[0024] (2) Divide B extruded material and C extruded material obtained in step (1) into double-layer complexes of B and C through a distributor, and then enter a stacking machine to superi...
