AI Technical Summary
Existing special cables are prone to aging and cracking in humid, high salt spray, and acid and alkali corrosive environments, and micro-cracks are difficult to repair on their own, resulting in decreased cable insulation performance, shortened service life, and high maintenance costs.
Using methyl vinyl silicone rubber, ethylene vinyl acetate rubber, and ethylene acrylate rubber as matrix materials, and adding basalt fiber, sheet boron nitride, flame retardant filler, catalyst microcapsules, and slow-release repair material, cable sheaths are prepared through radiation crosslinking. Self-repair is achieved by using catalyst microcapsules and slow-release repair material, thereby improving oil resistance and aging resistance.
It achieves long-term self-repair of the cable sheath, improves oil resistance and service life, avoids damage to the rubber matrix, and maintains the stability and protective performance of the cable.
