Problems solved by technology

This type of icing inhibitor is usually an organic liquid. On the one hand, this type of liquid is not stable and exists on the surface of the aircraft for a long time. It is used for a short time and requires repeated construction; on the other hand, the lost liquid will pollute the environment.
In recent years, it has been reported that the surface of hydrophobic or superhydrophobic materials can be used in the field of anti-icing. However, such materials can only delay icing or frosting to a certain extent. In addition, the mechanical properties of the surface of such materials are not good. Good, the surface structure is easily damaged during use and loses the effect of delaying freezing
[0004] Generally speaking, the anti-icing methods widely used at present generally have the disadvantages of high energy consumption, low efficiency, and easy pollution of the environment. Therefore, it is urgent to develop an anti-icing method that is easy to construct, low energy consumption, high efficiency, and pollution-free.

Abstract

The invention provides a mono-component hybridized aqueous anti-icing coating material. The mono-component hybridized aqueous anti-icing coating material mainly contains a hybridization emulsion, wherein the hybridization emulsion is a nanoparticle modified polymer emulsion preferably. The invention further provides a coating layer containing the coating material, a preparation method of the coating material, a coating method of the coating layer and a method for forming an anti-icing coating layer on the surface of a base material. As water serves as a dispersion medium, the mono-component hybridized aqueous anti-icing coating material provided by the invention is environment-friendly; after cured to form a film, the coating layer can have excellent wear resistance and prolonged service life; through coating the surfaces of base materials, such as metal, glass and macromolecular engineering materials, with the anti-icing coating layer, the ice adhesion strength of the surfaces of the base materials can be lowered, so that compared with the other similar materials, the material has the following advantages of simple process, wide applicable range, easiness in large-area construction, excellent anti-icing performance, excellent mechanical properties and easiness in coating layer repair.

Description

technical field [0001] The invention belongs to the technical fields of chemistry, chemical industry and materials, and relates to a single-component hybrid water-based anti-icing coating and a preparation method and application of the coating. Background technique [0002] Freezing rain, frost, snowfall and other weathers cause many inconveniences to people's lives. Seriously, this kind of weather often leads to ice coating on the surface of equipment such as roads, vehicles, ships, aircraft, power transmission line facilities, communication facilities, wind turbines, dams, offshore platforms, radar antennas and radomes. This icing phenomenon will not only cause damage and failure of equipment and facilities, causing economic losses, but also lead to major disasters and casualties. For example, the snowstorm in southern China in 2008 caused direct economic losses of up to 15 billion yuan. Another example is the phenomenon of icing on the wings of airplanes that has result...
