AI Technical Summary
Existing cables are prone to fires due to overload, short circuits and other faults during use, and their mechanical strength is insufficient in complex environments, making them difficult to effectively retard flames and withstand external forces.
By preparing phosphazene flame retardants and modified nanotube fillers, and combining specific steps to form flame-retardant fillers, high-strength cable protective sheaths are prepared. The phosphazene flame retardants generate active free radicals during combustion to interrupt the combustion chain reaction, and the modified nanotubes form a dense carbon layer to prevent the transfer of oxygen and heat.
This technology reduces the burning rate of cables at high temperatures, provides excellent flame retardancy and mechanical strength, enables normal use in complex environments, extends cable life, and reduces maintenance costs.
