Abstract

The invention discloses a high-weatherability anti-icing protective coating and a preparation method therefor. The protective coating disclosed by the invention comprises a high-weatherability organic coating with the thickness of 0.2mm to 1.5mm and a high-hydrophobicity nano-coating with the thickness of 0.1 to 1 micron, wherein the high-weatherability organic coating is formed by a 5% to 50% (w / w) snow melting agent laden polymer-based protective coating material, and the high-hydrophobicity nano-coating is formed through forming by a special process. According to the high-weatherability anti-icing protective coating disclosed by the invention, by high hydrophobicity and the laden snow melting agent, the coating can have an excellent anti-icing effect; and meanwhile, due to the high-performance polymer based protective material, the coating can have excellent weatherability and waterproof and anticorrosive performance.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a highly weather-resistant anti-icing protective coating and a preparation method thereof. Background technique [0002] Various infrastructure applications will be in contact with water in some way, such as long-term immersion, rain, dew, and even high-humidity air, etc., and water is pervasive and can penetrate or wet various concrete structures. Freezing occurs at zero degrees. When the water inside the structure is converted into ice, the volume will expand, resulting in freeze-thaw damage to the concrete, and the freezing of water on the surface of the structure will increase the load on the structure, cause various safety accidents, and even lead to some disasters, such as bridge decks or roads There are car accidents due to icing, so the development and application of functional high weather resistance anti-icing and anti-icing protective coatings have important signific...
