Preparation method of novel road super-hydrophobic anti-icing coating

Abstract

The invention relates to a preparation method of a novel road super-hydrophobic anti-icing coating, and belongs to the technical field of novel functional material preparation. According to the invention, microstructural features of a lotus leaf and an insect wing surface are used for reference, superhydrophobic performance is achieved by subjecting a micro-nano material to low surface energy treatment, and a binding material with good weather resistance is adopted to prepare the novel anti-icing coating. Firstly, nano-titanium dioxide is treated with stearic acid and ethyl alcohol for low surface energy structural recombination, so as to prepare modified nanocomposite particles with super-hydrophobicity; then, propylene oxide and hydroxy silicone oil are reacted with toluene diisocyanateto obtain moisture-curing type polyurethane; and finally, the composite particles and the moisture-curing type polyurethane are prepared into the novel anti-icing coating. The novel road super-hydrophobic anti-icing coating provided by the invention is capable of delaying the nucleation of ice crystals in the early stage of icing, inhibiting the growth of the ice crystals in the middle stage of icing, and enabling ice and snow to be removed easily in the later stage of icing. The coating is applicable to various types of road surfaces, is of great significance to the development of an active ice and snow removal technology, and has relatively good economic benefits.

Description

technical field [0001] The invention relates to a preparation method of a novel superhydrophobic ice-suppressing coating for roads, and belongs to the technical field of preparation of new functional materials. Background technique [0002] In recent years, frequent traffic accidents in winter and economic losses caused by snow and ice on roads have made the importance of snow melting and ice suppression systems for traffic engineering widely recognized at home and abroad. In winter, snowfall will occur in most parts of our country. The snow on the roads is easy to freeze under the action of vehicle load rolling and repeated freezing and thawing, causing vehicle brakes to slip, loss of direction control, serious traffic accidents, large-scale traffic paralysis, and serious obstruction. Traffic travel, people's normal life and economic development, even life-threatening. [0003] At present, relevant departments at home and abroad will prepare snow-plowing equipment and snow...

Problems solved by technology

[0017] The purpose of the present invention is to provide a method for preparing a novel superhydrophobic ice-suppressing coating for road use. The method is to ensure the equilibrium and stable state of the microstructure by controlling the modification process of nanomaterials. Currently, the mixing ratio of the film-forming components is being adjusted. During the process, the compatibility problem of polymer blends was solved, and a new type of superhydrophobic ice suppression coating was finally prepared, which provided technical basis and guarantee for improving the ice suppression performance of ice suppression materials
