Waterproof corrosion-resistant wire cable and preparation process thereof

The invention relates to the technical field of cables, in particular to a waterproof corrosion-resistant wire cable and a preparation process thereof. In order to enhance the waterproof and corrosion-resistant performance of the electric wire and cable, the insulating layer on the outer side of the electric wire and cable is improved; nano silicon dioxide is modified, a rigid benzene ring and a silicon-hydrogen structure are introduced to the surface of the nano silicon dioxide, and after the nano silicon dioxide is added to high-density polyethylene, silicon-hydrogen bonds in the modified nano silicon dioxide can react with double bonds in the polyethylene in a high-temperature environment, so that the nano silicon dioxide is introduced into a cross-linked network of the polyethylene; the wear resistance and chemical corrosion resistance of the insulating layer are improved, the stability of polyethylene is improved, and the water vapor erosion resistance of polyethylene is improved. 本发明涉及电缆技术领域，具体为一种防水耐腐蚀型
