Description

[0001] technical field [0002] The invention relates to the technical field of wire and cable manufacturing, in particular to a radiation-proof, weather-resistant, flame-retardant cable sheath material and a preparation method thereof. Background technique [0003] Large-scale military enterprises and enterprises shoulder the task of scientific research and modernization of national high-tech equipment, and most of the cables they need are high-temperature-resistant and light-weight fluorine-containing plastic products. In special fields such as military industry and nuclear power, due to the extremely harsh working environment, photovoltaic power plants need to use special cables with high temperature resistance and radiation protection. [0004] At the same time, the cable insulation material is an important part of the cable. It not only plays the role of insulation, but also plays the role of heat insulation and anti-corrosion. Once the insulation layer of the outer ...
