Abstract

The invention relates to the field of wires and cables, in particular to a wear-resistant and tensile-resistant cable sheath material and a preparation method thereof. The wear-resistant and tensile-resistant cable sheath material is prepared from, by weight, 70-105 parts of chlorinated butadiene rubber, 55-75 parts of phenolic resin, 13-24 parts of brominated polystyrene, 10-15 parts of white carbon black, 1-5 parts of magnesium oxide, 8-13 parts of isophthalate, 10-20 parts of petroleum microcrystalline wax, 9-13 parts of citrate, 13-23 parts of calcium stearate, 4-10 parts of dithiocarbamate, 20-27 parts of inorganic filler and 2-5 parts of surfactant. The cable sheath material is scientific and reasonable, a produced sheath has excellent physical properties, and a product has strong wear resistance, tensile strength, tear strength and resilience; the material has good heat resistance, flame resistance, radiation resistance, ozone resistance, acid and alkali resistance, chemical resistance, low production cost and long service life.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a wear-resistant and stretch-resistant cable sheath material and a preparation method thereof. Background technique [0002] With the gradual acceleration of the urbanization process, urban planning is becoming more and more modern. In the process of urban construction, cable entry into the ground has become the minimum construction requirement. At the same time, in the process of urban transformation, it is also necessary to put various cables erected in the air into the ground. At present, the construction of cables into the ground often adopts non-excavation technology. This construction method has the advantages of no impact on traffic, little damage to the stratum structure, and short cycle. , has the performance: the cable needs to have high strength, good rigidity and toughness, etc. In addition, due to the characteristics of the cable itself, it also needs to have the charac...
