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...

Abstract

The invention discloses a preparation method for a polyolefin cable material containing reclaimed materials. The cable material comprises the following components by weight: 90 to 110 parts of EVA, 15 to 40 parts of POE, 70 to 150 parts of aluminum hydroxide with a particle size of no less than 5500 meshes, 10 to 40 parts of nanometer montmorillonite, 5 to 8 parts of a modifier, 8 to 13 parts of maleic anhydride-grafted ethylene-octylene copolymer, 1.5 to 2.5 parts of dilauryl thiodipropionate and 3 to 5 parts of silicone master batch. In EVA, VA has percentage content of 30 to 33% and Shore hardness of no more than 70 A. The cable material has high pliability, excellent mechanical properties and capacity of realizing recycling of waste materials and is applicable to industries with high requirements for high cable pliability, e.g., communication cables and weak current cables.
