[0038] Table 1
[0039]
[0040] The radiation cross-linked polyolefin cable material with high processability is prepared through the following steps:
[0041] S1. Mix 70~100 parts of ethylene-octene copolymer, 10~20 parts of ethylene-vinyl acetate copolymer, 5~20 parts of FX-5924, 3~5 parts of silicone, 1~3 parts of glyceryl palmitoyl stearate Parts, 0.5~2 parts of nano-magnesium silicate, 0.5~2 parts of antioxidant, 0.1~1 part of light stabilizer are added to the internal mixer to mix and plasticize, and then conveyed into the screw extruder through double-cone shearing for extrusion, water Strand granulation to obtain the B material;
[0042] S2. 36~50 parts of ethylene-octene copolymer, 8~10 parts of ethylene-vinyl acetate copolymer, 15~20 parts of maleic anhydride grafted ethylene-octene copolymer, 5~20 parts...
