The introduction of nanotechnology brings revolutionary breakthroughs to flame retardant materials. Graphene/montmorillonite nanocomposites use intercalation technology to improve the flame retardant performance while maintaining the material flexibility. This nano-coating with a thickness of only 3 μm can shorten the vertical combustion self-extinguishing time of ordinary PVC cables to less than 5 seconds. The newly developed bionic flame retardant material developed by the laboratory of the University of Cambridge, imitating the hollow structure of polar bear hair, generates directional air flow when heated, and realizes active fire suppression. The upgrade of environmental protection regulations is reshaping the industry pattern. The EU ROHS 2.0 directive has included traditional flame retardants such as tetrabromobiphenol A in the list of banned ones, forcing enterprises to develop a new environmental protection flame retardant system. Bio-based flame retardants, such as phytic acid-modified chitosan, not only have excellent flame retardant properties, but their biodegradability is more in line with the requirements of the circular economy. According to the global flame retardant market data, the proportion of halogen-free flame retardants has exceeded 58% in 2023, and it is expected to form a new material market of US$32 billion by 2028. The intelligent detection technology has greatly improved the quality control level of flame retardant cables. The online detection system based on machine vision can monitor the dispersion uniformity of flame retardant in the extrusion process in real time, and increase the coverage rate of blind spots in traditional sampling detection from 75% to 99.9%. The infrared thermal imaging technology combined with the AI algorithm can identify the micro-defects of the cable sheath within 0.1 seconds, so that the product defect rate is controlled below 50ppm. The flame retardant performance prediction model developed by a Japanese company can accurately calculate the combustion level of the finished product through the material ratio parameters. In the era of smart cities and industry 4.0, flame retardant cables have gone beyond the scope of simple products and become an important node of the security ecosystem. From the lightning protection system of the Tokyo Skytree to the smart grid of the Tesla Super Factory, the flame retardant technology has always been silently guarding the energy lifeline of modern civilization. When the German TÜV certification body incorporates the life cycle assessment of flame retardant cables into the sustainable development indicators, what we see is not only the progress of materials science, but also the sublimation of human cognition of the essence of safety. This composite safety technology, which combines chemical, physical and intelligent monitoring, is redefining the safety standards of future infrastructure.
