Abstract

The invention relates to the field of cable materials, in particular to a waterproof, wear-resistant and flame-retardant sheath for cables and a preparation method thereof. The waterproof, wear-resistant and flame-retardant sheath for the cables includes the following specific components: 20-25 parts of EPDM rubber, 20-22 parts of polyester fiber, 10-12 parts of bituminous waterproof materials, 8-10 parts of carbon black, 6-8 parts of ceramic fine powder, 6-8 parts of silicon carbide fine powder, 5-7 parts of polyurethane waterproof seal coating, 3-5 parts of thickener, and 3-5 parts of antioxidants. The preparation method of the waterproof, wear-resistant and flame-retardant sheath for the cables includes the following specific steps: (1) mixing; (2) feeding; (3) thickening; (4) fiber formation; (5) extrusion. Compared with the traditional rubber sheath, the waterproof, wear-resistant and flame-retardant sheath for the cables adopts carbon black, ceramic fine powder and polyester fiber, thus the sheath not only has high wear resistance and high temperature resistance, but also has dense texture and is less prone to break. Finally, by the adoption of the polyurethane waterproof sealing coating, the waterproof, wear-resistant and flame-retardant sheath for the cables is waterproof and less likely to fall off and ignite, and receives double protection.
