Description

Technical field [0001] The invention relates to the technical field of cable materials, in particular to a weather-resistant and water-resistant cable sheath material. Background technique [0002] In recent years, with the development of national transportation engineering and ocean engineering, there are more and more electrical control equipment, the demand for cables will inevitably increase, and the performance requirements for cable materials will also become more and more stringent. Especially in some harsh environments, not only the cables used are required to have good heat resistance, moisture resistance, and sunlight resistance, but also excellent strength, heat resistance and weather resistance. However, the existing cables The weather resistance and water resistance of the material are not very satisfactory and need to be modified. Summary of the invention [0003] Based on the technical problems existing in the background art, the present invention proposes a weathe...
