Problems solved by technology

[0002] At present, most areas south of the Huaihe River in my country often suffer from "freezing rain" disasters. The fields of electric power, energy, communications, and bridges are facing serious icing and ice-covering problems, which makes high-voltage power transmission, towers, and bridge cables severely icing, causing drag breaking, collapsing, and falling ice, causing serious economic losses and major safety hazards

Abstract

The invention discloses a high-weather-resistance self-cleaning anti-icing coating and a preparation method thereof. The coating comprises a component A and a component B. When the coating is used, the two components are mixed, wherein the component A comprises, in percentage by weight, 15%-20% of a modified PDMS polymer, 50%-60% of fluororesin, 20%-34% of an organic solvent, 0.1%-0.5% of a wetting agent and 0.1-0.5% of a defoaming agent; the component B is prepared from, in percentage by weight, 70%-80% of an HDI derivative and 20%-30% of butyl acetate, the modified PDMS polymer is prepared by mixing 14.2% of dimethylchlorosilane and 85.8% of methylbenzene in weight ratio, and the HDI derivative is prepared by mixing hexamethylene diisocyanate, hexadecyl trimethyl ammonium hydroxide, dibutyl phosphate and methylbenzene. The high-weather-resistance self-cleaning anti-icing coating has ultra-low surface energy and high hydrophobicity and weather resistance, and after the coating is smeared on the surface of an object, the amount of water hung on the surface before icing can be reduced, so that loss and safety caused by ice and snow are reduced.

Description

technical field [0001] The invention relates to the technical field of self-cleaning coatings, in particular to a self-cleaning anti-icing coating with high weather resistance and a preparation method thereof. Background technique [0002] At present, most areas south of the Huaihe River in my country often suffer from "freezing rain" disasters. The fields of electric power, energy, communications, and bridges are facing serious icing and ice-covering problems, which makes high-voltage power transmission, towers, and bridge cables severely icing, causing drag break, collapse, and drop ice, causing serious economic losses and major safety hazards. How to reduce the amount of water hanging on the surface of objects before freezing has become a major problem from reducing the loss and safety caused by ice and snow. Contents of the invention [0003] The object of the present invention is to provide a high weather resistance self-cleaning anti-icing coating and a preparation m...
