Abstract

The invention is applicable to the field of coatings and provides an ice-coating-resistant coating and a preparation method and application thereof. The ice-coating-resistant coating comprises a component A and a component B, wherein the component A comprises hydroxy acrylic resin, a silane coupling agent, low-surface energy auxiliaries containing silicon, surface modification auxiliaries, diluents and other auxiliaries, and the component B is fatty acids isocyanate. The ice-coating-resistant coating is good in ice-coating-resistant durability, the water contact angle of the coating is large, the adhesive force between the coating and a substrate is good, mechanical performance is excellent, and the process is simple.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to an anti-icing coating, its preparation method and application. Background technique [0002] Icing and snow accumulation is a natural phenomenon. 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. However, for wind power systems, icing is a natural disaster, which seriously threatens the safe operation of wind power systems. [0003] As a clean renewable energy, wind energy has received more and more attention and is the most promising new energy. my country has abundant reserves of wind energy resources, but most of the abundant wind energy resources are distributed in the cold north and coastal areas with high humidity, and the working environment of wind turbines is very harsh. Especially when the wind power blades...
