Abstract

The invention discloses a high heat-resistant cable. The high heat-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 a modified natural rubber material; and the modified natural rubber material comprises following raw materials: natural rubber, fluororubber, carbon nano tube, nanometer aluminium oxide, modified attapulgite, stearic acid, zinc oxide, sulphur, 4,4-dithiodimorpholine, antioxidant 4010NA, lanthanum stearate, accelerant M, accelerant DM, accelerant TMTD, dicyclohexyl phthalate, and dioctyl phthalate. The high heat-resistant cable is excellent in heat resistance, high in strength, excellent in aging resistance, small in compression set, and long in service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high heat-resistant cable. Background technique [0002] Natural rubber has good processing performance and physical and mechanical properties; it has high elasticity and mechanical strength at room temperature, and it has low heat generation during multiple deformations, so it has excellent flex resistance; as a non-polar rubber, it is electrically insulating With good performance, it is one of the rubber materials frequently used in cable materials. However, in the existing cables, because the natural rubber molecules used contain a large amount of unsaturated double bonds, its heat resistance and aging resistance are not very ideal, and it is easy to age during processing, storage and use, thus shortening the cable life. The life of the cable increases the cost. Contents of the invention [0003] The invention provides a high heat-resistant cable, which has good heat resi...
