Problems solved by technology

[0004] Although there are related reports on superhydrophobic coatings in the field of transmission lines, because superhydrophobic coatings need to contact some putty in the air, the superhydrophobic properties are quickly lost, so superhydrophobic coatings cannot be used on a large scale for a long time. Reports on anti-icing of superhydrophobic coatings for transmission lines are only in the theoretical and laboratory stages, and cannot be applied on a large scale in the field.

Description

technical field [0001] The invention relates to the technical field of anti-icing coatings, in particular to an energy-absorbing super-hydrophobic and super-oleophobic anti-icing coating for power transmission lines and a preparation method of the coating. Background technique [0002] The vast majority of transmission lines in my country are directly exposed to the external environment, so they are extremely vulnerable to extreme weather, threatening the safe and stable operation of the power grid. Among them, freezing disasters have the greatest impact on the power grid and the widest range. Icing disasters will cause icing on transmission lines and even cause large-scale power outages and even collapse of the power grid. [0003] At present, there are dozens of relatively mature deicing technologies at home and abroad, which can be divided into three categories: natural external force deicing method, heating deicing method, and mechanical deicing method according to the p...
