Problems solved by technology

[0002] With the continuous development of the domestic economy and the acceleration of urbanization, urban rail transit, as a basic public welfare facility to solve urban travel convenience, has been widely recognized in many cities because of its fast, safe, comfortable, convenient, energy-saving and environmentally friendly features. With large-scale construction, urban rail cables have been widely used, among which the use of fire-resistant cables has increased significantly. In some important departments and public places, after a fire occurs, the packaging line can run normally for a period of time, which is of great help to rescue work. And can reduce casualties and property losses to a great extent. The outermost layer of the urban rail cable is a sheath, which is generally rubber or rubber synthetic sheath. The function of the sheath is to insulate and protect the cable from damage. Its fire resistance performance is the most important Good or bad plays a vital role in the safe operation of urban rail cables. Although a variety of fire-resistant cable sheath materials have been developed, they still cannot meet the needs. How to prepare a flame-retardant, environmentally friendly, and long-lasting urban rail Cable sheath material has become a technical problem that needs to be solved at present
