Problems solved by technology

However, recently some scholars, such as Stefan Jung, have studied various fluorine-containing low surface energy materials in detail and found that although superhydrophobic materials can prolong the freezing time, they generally freeze in about half an hour [JungS, Dorrestijn M, Raps D, et al.Are Superhydrophobic Surfaces Best for Ice-phobicity[J].Langmuir.2011, 27(6):3059-3066.], indicating that superhydrophobic materials have limited application effects in anti-icing
In particular, it is worth noting that a large number of on-site practices of many power grid companies show that in harsh weather conditions, super-hydrophobic coatings cannot effectively prevent icing

Abstract

The invention discloses an ice-covering-proof coating containing electrolyte, which consists of organic silicon modified polyelectrolyte, silicon fluoride modified acrylic ester, nanometer material, dissolvent, pigment, aleveling agent, a fire retardant and preservatives and bactericides. All the materials are as follows according to mass percents: 5 to 90% of organic silicon modified polyelectrolyte, 0 to 80% of silicon fluoride modified acrylic ester, 0.1 to 20% of nanometer material, 0 to 60% of dissolvent, 0 to 30% of pigment, 0 to 5% of leveling agent, 0 to 10% of fire retardant and 0 to 3% of preservatives and bactericides. The ice-covering-proof coating is obtained by uniformly grinding all the materials according to the amount. The ice-covering-proof coating is coated on the surfaces of parts such as high-voltage cables, iron towers, telecommunication lines, aircrafts and the like and can effectively prevent the parts from being covered by ice. The method is simple and practical in the engineering, is convenient to control and has lower cost and good using effect.

Description

technical field [0001] The invention relates to an anti-icing coating, which belongs to the technical field of materials. Background technique [0002] With the rapid development of modern industry, the reliability requirements for grid power supply are getting higher and higher. Icing and snowing are natural phenomena, but icing is a natural disaster for power systems, and icing lines seriously threaten the safe operation of power systems. The hazards caused by icing on transmission lines to the power system include mechanical and electrical accidents such as conductor galloping, disconnection, tower collapse, and flashover. Ice and snow on transmission lines seriously threaten the safe and reliable operation of power and communication networks. [0003] Generally speaking, the icing phenomenon of conductors is formed due to various meteorological reasons, which mainly include factors such as temperature, humidity, cold and warm air convection, circulation and wind speed....
