If the "Internet" is called the "information superhighway" of today's society, then the optical (electric) cable is the cornerstone of the "information superhighway." With the rapid development of communication technology, optical (electric) cables are widely used in various fields of our daily life and work. In the event of a fire, the maintenance of unimpeded communications at the site of the fire is critical to reducing casualties and property losses. Therefore, flame-retardant light (electric) cables play a very important role in today's society. The flame-retardant optical (electric) cable is mainly composed of a core (optical fiber or wire), a flame-retardant tape, a reinforcing member, and an outer sheath. In the event of a fire, the protection of the cable core and the smooth flow of communication mainly rely on the flame retardant bag inside the optical (electric) cable. At present, although commercial flame-retardant tapes have certain flame-retardant effects, their fire-resistant and heat-insulating properties are not ideal. In the fire, the temperature inside the light (electric) cables is high, which affects the communication quality and releases toxic gases and smoke. And endanger the safety of people present at the scene.
Recently, the research team led by Zhu Yingjie, a researcher at the Shanghai Institute of Ceramics, Chinese Academy of Sciences, has developed a new type of inorganic flame retardant fire-retardant and flame-retardant tape that is expected to be applied to optical (electric) cables. The stone ultra-long nanowires are used as the main material and are made of inorganic fiber "skeleton" materials and inorganic adhesives. The flame-retardant fire-retardant tape has excellent flame-retardant fire-resistance, can burn for a long time in the flame without burning, another advantage is that its thermal conductivity is very low, with excellent thermal insulation performance, can make the package in fire With a low internal temperature, the internal temperature of the tape can be further reduced by more than 150°C compared with the commercial flame retardant tape, which helps to protect the optical fiber or wire inside the optical (electric) cable and maintain high quality in a fire. communication. In addition, the flame-retardant fire-retardant tape is environmentally friendly, and no toxic and harmful gases are generated when the flame is burned. The excellent performance of fire-retardant and flame-retardant tape makes it has a good application prospect in the field of flame-retardant optical (electric) cables. Related research work was published in the international journal "European Chemistry" (Li-Ying Dong, Ying-Jie Zhu, A New Kind of Fireproof, Flexible, Inorganic, Nanocomposite Paper and Its Application to the Protection Layer in Flame-Retardant Fiber-Optic Cables , Chemistry-A European Journal, 19, 4597-4604 (2017) ), was incorporated into the cover paper. Related research work applies for an invention patent.
The research work is one of the series of research work on hydroxyapatite ultra-long nanowire-based novel inorganic refractory paper, which further expands the application field of new inorganic refractory paper. In 2014, the Zhu Yingjie team used the hydroxyapatite ultra-long nanowires as a raw material for the first time to successfully develop a new type of inorganic fire-resistant paper, which made “paper-laden fire†a reality (Chemistry–A European Journal, 20, 1242–1246 ( (2014), related research work has received extensive attention and extensive coverage from domestic and foreign media and companies, such as Materials Today, American Ceramic Society, Chemistry Views, Chemical Engineering, Decoded Science, CCTV, People's Daily, etc. After more than three years of unremitting efforts. The team has made a series of research progresses in the field of new inorganic refractory papers. For example, it has developed a method for preparing hydroxyapatite ultra-long nanowires (Ceramics International, 41, 6098–6102 (2015); Materials Letters, 144, 135–137 (2015)); Development of new hydroxyapatite long nanowire-based high-efficiency antibacterial fire-resistant paper (Chemistry–A European Journal, 22, 11224–11231 (2016), selected for cover papers and papers), novel hydroxyls Apatite long nanowire waterproof and fire resistant paper (ACS Applied Materials & Interfaces, 8, 34715–34724 (2016)), novel hydroxyphosphorus Graystone ultra-long nanowire-based rapid test strips (Chemistry–A European Journal, 23, 3328−3337 (2017), selected for cover papers and hot papers) and hydroxyapatite ultralong nanowires with ordered nanowires and flexible refractory Fabrics (ACS Nano, 10, 11483–11495 (2016)) et al.
The relevant research work was supported by the Shanghai Science and Technology Commission, the China Postdoctoral Science Foundation, and the Shanghai Institute of Silicate Innovation Project of the Chinese Academy of Sciences.
