Abstract

The invention discloses a high-strength heat-resistant cable and a preparation method thereof. The preparation method comprises: 1) the preparation of a cable rubber sleeve: A, placing bentonite and illite powder at a temperature of 450-600 DEG C for roasting to obtain calcined powder; B. immersing the calcined powder in organic amine for 20 to 50 minutes to obtain modified powder; C, mixing styrene-butadiene rubber, EPDM rubber, modified powder, diphenylurea, zinc borate, stearic acid, vulcanizing agent, accelerator and anti-aging agent to be smelted and extruded to obtain cable rubber sleeve; 2) the preparation of wire core: stranding multiple silver-plated copper-clad steel to obtain the wire core; 3) the preparation of the cable: covering the cable rubber sleeve with the wire core to obtain a high-strength heat-resistant cable. The high-strength heat-resistant cable achieves high strength and high temperature resistance.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a high-strength heat-resistant cable and a preparation method thereof. Background technique [0002] As a widely used power facility, cables are widely used in production and life, and power facilities such as cables are also used in the aerospace field. In the process of use, due to the different use environments, and with the continuous advancement of science and technology, the requirements for the performance of the cables are getting higher and higher, and they are also required to be able to adapt to the needs of harsher environments. The adaptation of the cable to the environment often depends on the performance of its outer cable rubber sheath. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide a high-strength heat-resistant cable with high strength, which can be used in a high-temperature environment, and has a good performance of...
