Two-component waterborne wear-resisting and low-ice-adhesion anti-icing coating and coating layer, and preparation methods and applications thereof

Abstract

The invention provides preparation methods of a two-component waterborne wear-resisting and low-ice-adhesion anti-icing coating and a coating layer thereof. The two-component waterborne anti-icing coating is composed of a component A containing a core-shell structure polymer emulsion and inorganic nanoparticles and a component B containing a curing agent. An outer layer of the core-shell structure polymer emulsion in the component A of the anti-icing coating is a hydrophilic shell layer, so that polymer emulsion particles can be stably dispersed in water, and the advantages of being green and environmentally friendly are provided. The inorganic nano particles in the component A are rigid particles, can improve the mechanical properties of the anti-icing coating layer, endow the coating layer with excellent wear resistance and prolong the service life of the coating layer. After the coating is cured into a film, the hydrophilic shell layer of the polymer emulsion particles can absorb moisture, and thus a water lubricating layer is formed on the surface of the coating layer; when the coating layer surface is iced, due to the existence of the water lubricating layer, the acting force between ice and the coating layer is decreased, besides, the substrate surface roughness is also reduced, and the contact area between the ice and the substrate is decreased.

Description

Technical field

[0001] The invention belongs to the technical fields of chemistry, chemical engineering and materials, and relates to the preparation and application of a wear-resistant, low-ice adhesion anti-icing coating composed of a core-shell structure polymer emulsion. Background technique

[0002] Ice and accumulation on roads, airplanes, ships, offshore oil platforms, wind turbines, dams, power lines, and telecommunications equipment have brought huge hazards and potential safety hazards to people’s lives and property. For example, road icing increases the probability of traffic accidents; large-scale snowfall and frost weather causes icing of cables and wires, resulting in damage to the power transportation system and huge losses to the national economy; icing on aircraft surfaces and wings threatens flight safety. For example, many plane crashes in Baotou, China, the United States and Siberia in Russia in recent years are all related to wing icing. The current anti-ici...
