Production method of super-hydrophobic ice coating for ship deck deicing

Abstract

The invention relates to a production method of a super-hydrophobic ice coating for ship deck deicing. The super-hydrophobic ice coating is coated on a ship deck, and when a liquid is solidified intoice on the surface of the super-hydrophobic ice coating, the coating can reduce ice and snow accumulation by reducing an adhesive force of the ice, and ice covering the surface is easy to remove; andespecially in the field of ship deck deicing, when marine equipment operates on a deck, if the deck is frozen, the equipment cannot be normally used, and great influences are caused to production andlives of crews, and therefore, prevention of ship deck freezing and deck deicing are the main research direction of deck deicing. In the invention, a problem of adhesion on the surface of the ship deck is solved, and excellent self-cleaning, self-repairing and super-hydrophobic ice performance is possessed.

Description

technical field [0001] The invention belongs to the field of preparation of anti-icing coating materials, and in particular relates to a preparation method of a super-ice-phobic coating used for deicing ship decks. Background technique [0002] Water will freeze when it is cold, and freezing will cause difficulties in the operation of various equipment, safety hazards, and high equipment maintenance costs; the antifreeze and deicing of ships has always been an urgent problem to be solved; especially in cold climates, The open-air surface of the ship is exposed to high humidity and the temperature is at zero or close to zero. It is most likely to freeze, especially the portholes of the wheelhouse, deck machinery, hatch covers, communication and navigation equipment, etc. Freezing will lead to some catastrophic events For example, the loss of life and property caused by the sinking of the ship and the damage of the power line will be very dangerous; traditional deicing is most...

[0002] Water will freeze when it is cold, and freezing will cause difficulties in the operation of various equipment, safety hazards, and high equipment maintenance costs; the antifreeze and deicing of ships has always been an urgent problem to be solved; especially in cold climates, The open-air surface of the ship is exposed to high humidity and the temperature is at zero or close to zero. It is most likely to freeze, especially the portholes of the wheelhouse, deck machinery, hatch covers, communication and navigation equipment, etc. Freezing will lead to some catastrophic events For example, the loss of life and property caused by the sinking of the ship and the damage of the power line will be very dangerous; traditional deicing is mostly manual deicing, which is time-consuming, laborious, inefficient and dangerous, and mechanical deicing will cause serious damage to the surface of the ship. damage is not to be advocated; therefore a great deal of research has been done on anti-icing and de-icing technologies

[0003] At present, deicing methods for polar navigation ships and offshore platforms are divided into active deicing methods and passive deicing methods according to the deicing form; active methods refer to deicing by external forces after icing, including mechanical, salt, electric heating, infrared and other deicing methods, using heating and chemical methods to melt ice is the most common deicing method. For example, patent 201310013318.9 discloses an anti-freezing and anti-icing electronic control device for wind turbine blades; although this method uses Heating with an external system can reduce the rate of icing, but this requires a lot of extra energy; the chemical method is generally to use snow melting salt to deice, this method is often used in road snow removal and ice, but salt has corrosion to ship steel plates Therefore, more serious losses are caused; the present invention aims to use the physical properties of the surface of the object and the properties of the coating material itself to prevent ice from condensing to the coating or reduce the ice adhesion strength and rely on wind or self-gravity to make the ice detach surface, this method of deicing consumes less energy and does not create corrosion problems
