Problems solved by technology

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] The use environment of the existing cables is relatively harsh, and aging phenomena are prone to occur during use, which makes the cables lose their functions and shortens the service life of the cables

Abstract

The invention discloses a high-strength ageing-resistant cable, which comprises a cable core, wherein the cable core comprises a conductor and an insulating layer, wherein the conductor is located in the middle part; the insulating layer coats outside the conductor; an inner sheath layer is arranged outside the cable core; a steel belt armor layer is arranged outside the inner sheath layer; an outer sheath layer is arranged outside the steel belt armor layer, and is fabricated by a modified natural rubber material; and the modified natural rubber material comprises the following steps: natural rubber, epoxy resin, fluorine micro-powder, white carbon black, a nylon short fiber, a modified calcium carbonate whisker, modified nano titanium dioxide, nanometer aluminum oxide, stearic acid, zinc oxide, sulphur, N,N'-m-phenylenedimaleimide, dicumyl peroxide, 4,4'-diaminodiphenylmethane, butadiene sulfone, an accelerant tetraethylthiuram disulfide (TETD), an accelerant MZ, an accelerant NS, a load-type anti-aging agent, an anti-aging agent RD, a plasticizer and a silane coupling agent. The high-strength ageing-resistant cable disclosed by the invention is high in strength, good in ageing resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength 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] The use environment of existing cables ...
