Abstract

The invention discloses an insulating cable for aerospace, and a preparation method thereof. The preparation method comprises: 1) twisting a plurality of wires to obtain a core wire; 2) mixing and melting silicon powder, a silane coupling agent, disodium ethylenediaminetetraacetate, epoxy resin, nano-silica, nitrile butadiene rubber, cis-butadiene rubber, tetramethylthiuram disulfide, stearic acid, calcium oxide nano-particles, a curing agent and an accelerant, and performing extrusion molding to prepare a wire sheath; and 3) covering the core wire with the wire sheath, and filling glass fiberand cotton fiber mixed fibers between the wire sheath and the core wire to obtain the insulating cable for aerospace. The above design realizes a good insulating performance.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to an insulated cable for aerospace and a preparation method thereof. Background technique [0002] Cables are widely used for their good performance. During the use of the cable, its insulation performance will greatly determine its performance and scope of use. Ordinary cables often have mediocre insulation properties, so that they often cannot meet actual needs in use, especially in aerospace and other fields. [0003] Therefore, it is an urgent problem to be solved in the present invention to provide an insulated cable for aerospace with good insulation properties and a preparation method thereof. Contents of the invention [0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problem that the common cables in the prior art often have general insulation properties, so that they often cannot meet the actual needs in use, espec...
