[0002] In recent years, the special waterproof properties of lotus leaf surface have attracted widespread attention. Studies have found that the multi-layered micro-nanostructure and hydrophobic waxy materials on the lotus leaf surface give it excellent super-hydrophobic properties. This special wettability gives it great application prospects in the fields of waterproofing, oil-water separation, anti-icing, corrosion resistance, self-cleaning, microfluidic transportation, etc. Especially in the field of anti-icing, the special wettability of super-hydrophobicity can not only reduce the accumulation of ice, but also effectively reduce the adhesion between ice and substrate, thereby achieving the purpose of anti-icing.

[0003] Hydrophobic powders such as fluorinated silica are added to the hydrophobic coating solution. However, due to the hydrophobic properties of the hydrophobic powder, the air in the hydrophobic coating solution will adhere to the surface of the hydrophobic powder, and multiple hydrophobic particles wrapped in bubbles will aggregate to form hydrophobic powder clusters, thereby reducing the production quality and production efficiency of the hydrophobic coating solution.

[0007] The solute delivery pipeline is provided with a second gate, a second material discharge gate is slidably inserted in the second gate, and the second gate is located between the preparation barrel and the powder delivery pipeline;

[0008] An exhaust pipe is arranged on the molten powder conveying pipe and below the first gate, and an exhaust check valve is arranged at one end of the exhaust pipe.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 4 As shown, a mixing assembly for preparing a double super-hydrophobic railway contact network anti-icing coating material includes a preparation barrel 2 with an agitator 1 disposed therein, a vacuum tank 3, a solute conveying pipeline 4 and a powder conveying pipeline 5, one end of the solute conveying pipeline 4 is connected to the preparation barrel 2, and the discharge port of the vacuum tank 3 is connected to the solute conveying pipeline 4 through the powder conveying pipeline 5;

[0028] Specifically, a solvent is added into the preparation barrel 2, and a hydrophobic powder to be added, such as fluorinated silica, is added into the vacuum tank 3, and then the vacuum tank 3 is evacuated by a vacuum pumping device, and then the solute is filled into the solute conveying pipe 4, so that the solute overflows into the powder conveying pipe 5, and the air in the powder conveying pipe 5 is discharged through the exhaust pipe 10 and the exhaust check valve 11. Subsequently, the first unloading gate 7 and the second unloading gate 9 are operated in sequence, and the solute is continuously added to the solute conveying pipe 4 at the same time, so that the hydrophobic powder in the vacuum tank 3 and the solute are preliminarily mixed in a vacuum or near-vacuum environment and then injected into the preparation barrel 2 together, and mixed evenly with the solvent in the preparation barrel 2 under the stirring of the agitator 1, thereby avoiding the hydrophobic powder from contacting with air during the addition process to the preparation barrel 2, causing the hydrophobic powder to be wrapped by bubbles, resulting in a large number of hydrophobic powder clumps aggregated by bubble wrapping in the prepared coating solution, thereby facilitating the uniform distribution of the hydrophobic powder in the coating solution, while ensuring the production quality of the coating solution, helping to reduce the time of stirring the coating solution, thereby improving the production efficiency of the coating solution.

[0029] It should be noted that the first material discharge gate 7 and the second material discharge gate 9 always keep the corresponding first gate 6 and the second gate 8 closed.

When the solute fills the solute conveying pipeline 4 and the fixed conveying channel below the first unloading gate plate 7, the first unloading gate plate 7 and the second unloading gate plate 9 are opened in sequence, and the solute is continuously supplemented to the solute conveying pipeline 4 during the process of adding the solute and the hydrophobic powder, so as to realize that the hydrophobic powder and the solute are premixed in a vacuum or near-vacuum environment and then injected into the preparation barrel 2, which is beneficial to the uniform distribution of the hydrophobic powder in the coating solution, thereby achieving the purpose of improving the production quality and production efficiency of the coating solution.

[0031] Preferably, one end of the solute delivery pipeline 4 is tilted downward, and the lower end of the solute delivery pipeline 4 is connected to the preparation barrel 2 to facilitate the solute to fill the solute delivery pipeline 4 and the powder delivery pipeline 5 below the first unloading gate 7 and exhaust the air.
