High-stability cable
A high stability, cable technology, applied in the direction of circuits, power cables with shielding layer/conductive layer, electrical components, etc., can solve the problem that the cable shielding effect is difficult to meet high-end requirements, the volume resistivity of the cable shielding material is high, and the number of impurities is large To achieve the effect of improving the space potential distribution and surface properties, improving the shielding effect and stability, and improving the dispersion effect

Embodiment 1
[0028] A high-stability cable includes a conductor, a semiconductive shielding layer, an insulating layer, a flame-retardant layer, an armor layer and a sheath from the inside to the outside, and the semiconductive shielding layer is composed of a semiconductive shielding material.
[0029] The semi-conductive shielding material comprises the following raw materials in weight percentage: polyethylene 50%, ethylene-vinyl acetate copolymer 20%, modified carbon black 19%, diethyl carbonate 10%, crosslinking agent 0.5%, antioxidant 0.5%.
[0030] The preparation method of described modified carbon black comprises the following steps:
[0031] Step 1: carbon black pretreatment, carbon black is soaked in lye for 24 hours, washed with water, soaked in nitric acid for 24 hours, washed with deionized water, and activated by calcination under an inert atmosphere to obtain activated carbon black;
[0032] Step 2: Add the activated carbon black to the 2+ and Co 2+ In the aqueous soluti...
