When the solid content of the environment-friendly cable anti-sticking agent in example 1 is adjusted to 3%, the phenomena of adhesion and viscous marks exist on the surface of the wire rod when the wire rod is subjected to irradiation crosslinking. It is shown that when the solid content is less than 7%, the viscosity increases, which leads to blocking. Comparative example 1 no sodium alcohol ether sulphate and polyoxyethylene ether are added, which causes adhesion, impression and pull mark between cables; comparative example 2 no polyether polyol was added, resulting in blocking, coining, and pull marks between the cables; comparative example 2 no surfactant was added, resulting in blocking, coining, and pull marks between the cables. In the embodiments 1-3, polyether polyol, fatty alcohol-polyoxyethylene ether sodium sulfate and silicone oil are added, and the polyether polyol, the fatty alcohol-polyoxyethylene ether sodium sulfate and the silicone oil interact with each other, so that adhesion, imprinting and drawing marks between cables are inhibited.
