Problems solved by technology

[0003] The rubber sheath material of traditional cables is affected by heat energy, mechanical energy, light energy and radiation energy during long-term storage and use, plus the chemical reactions involving oxygen, ozone, moisture, variable-valence metals and metal ions, the rubber sheath material gradually The aging phenomenon of becoming soft and sticky, hard and brittle or cracked will cause its physical and mechanical properties to deteriorate or even lose its original performance, causing the cable to fail during use, thereby causing other components inside the cable sheath to break down. Corrosion makes the cable unable to operate normally, and during use, due to friction with other objects, the rubber surface is damaged or even loses its original performance, and the rubber is used for too long, and the aging speed becomes faster. Therefore, How to prepare a cable sheath material with excellent aging resistance has become a technical problem to be solved at present

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to an aging-resistant cable sheath material. Background technique [0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. There are strict requirements on performance, aging resistance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. [0003] The rubber sheath material of traditional cables is affected by heat energy, mechanical energy, light energy and radiation energy during long-term storage and use, plus the chemical reactions involving oxygen, ozone, moisture, variable-valence metals an...
