Embodiment 1
[0014] A processing method of polyolefin cable material containing recycled materials. Weigh polyolefin powder and silane according to the following formula, mix them evenly as modifiers, and add modifiers, flame retardants, and flame retardant synergists to high-speed mixing In the machine, stir at 45~50℃ for 25~30min at high speed for surface activation treatment; weigh the other components according to the formula together with the modified flame retardant and flame retardant synergist and stir at low speed for 3~5min in the mixer ; Send the mixed raw materials into a twin-screw extruder with a forced feeding system for plasticization, granulation, and packaging. The temperature of each zone of the screw is between 120 and 145°C.
[0015] The product formula is as follows: 30 parts of recycled low-smoke halogen-free cable sheath, 90 parts of EVA, 15 parts of POE, 70 parts of magnesium hydroxide with particle size ≥ 5500 mesh, 10 parts of nano-montmorillonite, 5 parts of modifie...
