Abstract

The invention discloses an aging-resistant cable. The aging-resistant cable comprises a cable core; the cable core comprises conductors arranged at the middle part, and insulating layers used for coating the conductors; the cable core is coated with an inter sheath layer; the inter sheath layer is coated with a steel belt armour layer; the steel belt armour layer is coated with an outer sheath layer; the outer sheath layer is made of an aging-resistant modified butadiene styrene rubber material; and the aging-resistant modified butadiene styrene rubber material comprises butadiene styrene rubber, epoxy resin, liquid nitrile rubber, precipitated white carbon black, modified aramid fiber, modified nano titanium dioxide, stearic acid, zinc oxide, magnesium oxide, sulphur, dicumyl peroxide, 4,4'-Diaminodiphenyl methane, iminazole, butadiene sulfone, an accelerant, a novel anti-aging agent, anti-aging agent 4010, a plasticizer, and a coupling agent. The aging-resistant cable possesses excellent mechanical properties, and is excellent in aging resistance, and long in service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aging-resistant cable. Background technique [0002] With the development of my country's petrochemical, communication, transportation, construction, electric power and other industries, higher requirements are put forward for the performance and quantity of cables. Therefore, the rubber used as cable materials is gradually becoming high-grade, specialized and specialized. At present, the rubber compounding technology of rubber materials for cables in my country is backward, and the existing rubber varieties and properties cannot meet domestic demand. Therefore, the original rubber material formula is changed, the properties of rubber materials are improved, and a variety of high-performance rubber materials for cables are obtained. Adapting to the diverse needs of the cable market is a hot topic in current research. [0003] Styrene-butadiene rubber is the backbone product of ...
