Problems solved by technology

Although there are reports on anti-icing of super-hydrophobic materials, super-hydrophobic anti-icing mainly relies on low adhesion to ice, and the melting temperature still needs to be above 0°C. Therefore, there is an urgent need for a super-hydrophobic material that can reduce the melting temperature.

Abstract

The invention discloses an energy-absorbing super-hydrophobic anti-icing coating for insulators and a preparation method of the energy-absorbing super-hydrophobic anti-icing coating, and relates to the technical field of coatings. The energy-absorbing super-hydrophobic anti-icing coating comprises primer and finish. The primer comprises 10-20 parts of fluorine-silicon resin and/or fluorine-carbon resin, 20-25 parts of epoxy resin and/or acrylic resin, 10-15 parts of inorganic filler and 40-50 parts of a solvent. The finish comprises 2-5 parts of polytetrafluoroethylene powder, 1-2 parts of carbon black, 1-3 parts of titanium dioxide and 90-96 parts of modified nano silicon dioxide dispersion liquid. The coating has the beneficial effects that the coating has the characteristics of super-hydrophobicity, insulation, icing delay, ice reduction and low-temperature deicing, can effectively solve the icing problem of an insulator of a power system, and can be applied to power equipment such as an insulator.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an energy-absorbing superhydrophobic anti-icing coating for insulators and a preparation method thereof. Background technique [0002] Most of the transmission lines in our country are directly exposed to the external environment, and the insulators on the transmission lines are extremely vulnerable to extreme weather, which threatens the safe and stable operation of the power grid. Among them, the greatest impact on the power grid and the widest range should be the freezing disaster, which will cause the insulators of the transmission line to be covered with ice, greatly reduce the insulation function of the insulators, and easily cause ice flash problems. 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 meth...
