Kelver super wear-resistant cable and preparation method thereof

Abstract

The invention provides a Kelver super wear-resistant cable and a preparation method thereof. The cable comprises a Kelver core body and a sheath wrapping the periphery of the Kelver core body. A plurality of bundles of aramid fibers and conductive wires are stranded, so that a Kelver composite material can be obtained; the obtained Kelver composite material and resin are bonded together through solidification, so that the Kelver core body can be formed. The sheath includes a mica layer wrapping the outer periphery of the Kelver core body and a polyurethane rubber layer wrapping the outer periphery of the mica layer. The raw materials for preparing the resin include the following components in parts by mass: 40 to 50 parts of cyanate resin; 20 to 30 parts of polymethyl silicone resin; 10 to15 parts of poly (ethyl phenyl) organic silicone resin; 5 to 8 parts of trimethoxysilyl propyl diethylenetriamine; 0.05 to 4 parts dibutyltin dilaurate; 4 to 10 parts of trimethylolpropane glycidyl ether; and 5 to 8 parts of liquid nitrile rubber. According to the Kelver super wear-resistant cable of the invention, when the sheath is worn after being used for a long time, and the Kelver super wear-resistant cable can be still used.

Description

technical field [0001] The invention belongs to the technical field of electric cables, and in particular relates to a bulletproof super wear-resistant electric cable and a preparation method thereof. Background technique [0002] Most of the cables in the prior art only use metal materials as the core. This kind of cable has low tensile strength, heavy weight, low long-term high temperature resistance, and limited service life. It is easy to cause internal wire core fusing to cause power outage and power failure, which seriously affects the requirements of daily life and industrial production for power transmission. It is difficult to use it for a long time under harsh conditions and has become a bottleneck in the development of the power industry. [0003] At present, the rubber power cords of outdoor electric tools on the market, such as cutting machines, are often dragged back and forth on hard ground. With the continuation of use time, the rubber power cords will age at...
