Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a cold-resistant cable sheath material. Background technique [0002] The climate in some areas of our country is extremely cold, the temperature difference between day and night is large, the ultraviolet radiation is strong, and there are frequent strong lightning in some areas. As the railway nervous system, the cable must have excellent corrosion resistance, cold resistance, and anti-ultraviolet in the alpine areas with harsh climate conditions. performance. Although a variety of cold-resistant and corrosion-resistant cable sheath materials have been prepared at present, they still cannot meet the increasingly harsh environmental requirements in some special areas. How to prepare a cable sheath material with excellent cold resistance and good corrosion resistance has become a problem that needs to be solved at present. technical problem.
