Background
With the progress of science and technology, the modern industry cannot keep away with electric energy, but the high development of the modern society and the wide application of electronics and electric power have to lead people to live in the enclosure of various cables which are criss-cross and dense like cobweb. In general, it is difficult to anticipate the danger that may happen around us at any time. In many places such as high-rise and super high-rise buildings, large entertainment places, large industrial and mining places, enterprises and underground engineering, cables are often densely erected, and in case of fire, fire can be delayed along the cables and spread to other departments and floors. In urban fires, which are caused in large part by the spread of cable fires caused by electrical equipment failure or overloading of cables, the most significant hazard factor is the presence of large quantities of toxic gases and smoke. Traditional flame-retardant cables and low-halogen low-smoke flame-retardant cables are widely prepared from a mixture of a halogen-containing polymer and a halogen-containing flame retardant. Although these cables have good flame retardant properties, in the event of a fire, the cables generate a large amount of smoke and toxic corrosive gases after burning, which not only hinder fire fighting work and personnel evacuation, but also corrode instruments and equipment. With the continuous progress of cable technology, a halogen-free, low-smoke, green and environment-friendly fire-resistant cable becomes an important direction for new product development, however, the flame retardant property of the existing halogen-free, low-smoke cable needs to be improved.
