Description

technical field [0001] The invention relates to the technical field of cables, in particular to a flame-retardant and high-temperature resistant insulating material for cables and a preparation method thereof. Background technique [0002] With the continuous expansion of the scale of China's electric power industry, data communication industry, urban rail transit industry, automobile industry, shipbuilding and other industries, and the rapid increase in the demand for wires and cables, the wire and cable industry still has huge development potential in the future. In the event of a fire, a type of cable that can ensure the integrity of the line can continue to provide power and transmit various signals normally when the fire is high temperature, which provides a guarantee for fire control and survival. [0003] In the prior art, cables are used in dense places such as theaters, subways, and airports. Although they can have the effect of fire resistance and high temperature ...
