Abstract
The invention relates to the technical field of anti-icing, and discloses an anti-icing coating, a preparation method and application thereof. The coating comprises an anti-icing inner layer, an anti-icing middle layer and an anti-icing outer layer; the anti-icing inner layer comprises a matrix I and a filler I, wherein the filler I is at least one of silicon dioxide and titanium dioxide; the anti-icing intermediate layer comprises a matrix II and a filler II, wherein the filler II is at least one of aluminum oxide, aluminum nitride and magnesium oxide; the anti-icing outer layer contains composite metal oxide, metal acid salt and a matrix III. The anti-icing coating provided by the invention can raise the surface temperature of the coating, accelerate the surface ice melting to form a water film, and promote the ice layer to fall off; the heat dissipation rate can be delayed, the wear resistance of the coating is improved, and the inner side coating and the base material are protected; the heat generated by the coating can be concentrated on the surface, so that the heat utilization rate is improved; therefore, the anti-icing agent has the advantages of good anti-icing effect, high wear resistance and weather resistance, high economical efficiency and the like.
Description
Technical Field
The invention relates to the technical field of anti-icing, in particular to an anti-icing coating and a preparation method and application thereof.
Background
With the continuous growth of the wind power industry in China, the problems of wind power equipment in the running process are also continuously displayed. When the fan blade runs under the low-temperature condition or encounters rainwater, ice and snow and supercooled water drops, the phenomenon of frozen ice is very easy to occur, the power generation efficiency of the fan is affected, and equipment is stopped when serious. These accidents can bring serious disasters to large areas, and form a huge threat to national security and life and property security of people.
CN115232529a discloses an anti-icing coating, characterized by comprising a surface layer composed of an oil-water gel, the oil-water gel comprising an oil gel component and a hydrogel component forming an interpenetrating network structure, the hydrogel component comprising quaternary ammonium chitosan, and the quaternary ammonium chitosan being cross-linked to each other by a divalent anion, the divalent anion being a sequencing ion having a higher chaotropic sequence than chloride ion. When the anti-icing coating is used for the fan blade, the recrystallization of ice crystals on the windward side of the fan blade can be inhibited, the adhesiveness of the ice layer on the windward side of the fan blade is reduced, and even if ice cubes are formed, the ice crystals can be blown off by air flow because the ice crystal particles are small and can not adhere on the windward side, so that the ice layer accumulation can not be formed on the fan blade. When the fan runs in a low-temperature environment, the aerodynamic shape of the fan blade can be not influenced by the ice layer, and the aerodynamic performance can be kept. However, the anti-icing coating has poor wear resistance, is easy to crack or fall off under long-time running conditions, and has short service life.
CN105032731a discloses a preparation method of an energy-saving deicing coating compounded by a superhydrophobic coating and a heating coating, which is characterized in that: the method comprises the following specific steps: step one: polishing the substrate by sand paper or performing sand blasting treatment, and repeatedly cleaning to obtain a clean and rough surface so as to improve the binding force of the coating and the substrate; step two: coating with heat insulation effect is sprayed on the surface of the treated base material, so that heat is prevented from being transferred into the material, and the heat efficiency is improved; step three: masking the cured heat-insulating coating with adhesive tape without masking the sprayed part, carrying out hydrophilization treatment, and spraying a heating coating on the treated surface to obtain a uniform and uniform thickness coating surface; step four: and spraying a waterproof protective coating with heat conduction property on the surface of the heating coating to protect the heating coating from being wetted by rainwater and the like. The anti-icing coating has the advantages of both coating anti-icing and electrothermal anti-icing, and the heating mode is changed to improve the heat efficiency, so that the high-efficiency energy-saving anti-icing is realized. However, the heat conducting gel adopted by the anti-icing coating has low heating efficiency, is difficult to generate enough heat for melting and falling off the ice layer, and needs an external power supply and consumes electric energy, so that the construction difficulty is high, and the anti-icing cost is high.
