Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a flame-retardant, heat-resistant and 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. Performance and other indicators have strict requirements. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, high temperature deformation, poor mechanical properties, and short service life. It brings a lot of inconvenience to the actual use, and even threatens the safety of people'...
