Embodiment 1

[0027] 1) Preparation of fluorosilicone acrylate copolymer

[0028] Methyl isobutyl ketone (10 g) was added into a reactor (250 ml), nitrogen was blown, and the mixture was heated to 70°C. A solution composed of cyclohexyl methacrylate (12g), butyl acrylate (9g), hydroxyethyl methacrylate (2g), and methyl isobutyl ketone (5g) was added dropwise, while another constant pressure A solution consisting of methyl isobutyl ketone (5 g) and azobisisobutyronitrile (0.3 g) was added dropwise through the funnel, and reacted at this temperature for about 3 hours. Then the remaining azobisisobutyronitrile (0.15 g) and dodecafluoroheptyl methacrylate (6 g), 4-methacryloxybutyl-heptastyryl POSS (1 g) and the remaining Methyl isobutyl ketone (10 g) was reacted at 70° C. for 24 hours, and the temperature was lowered to obtain a translucent emulsified solution. Cool down to 30°C, discharge and store.

Abstract

The invention discloses a hydrophobic anti-ice and snow coating of a fluorosilicone acrylate copolymer and a preparation method of the coating. The paint includes ethyl acetate as a solvent, and the solute contained in the solvent is a fluorosilicone acrylate copolymer and a curing agent. The process of preparing the coating with the coating includes using aluminum flakes as the substrate, cleaning the surface with acetone and water, and drying; the coating is sprayed with a spray gun, powered by air, and sprayed at different distances from the surface of the substrate to obtain micro-nano Superhydrophobic coating with raised rough structure. The invention has the advantages of simple coating preparation process, easy-to-obtain raw materials, good film formation, high strength and hardness of the formed coating, and is widely used for surface coating of outdoor facilities such as transportation and power transmission. The coating preparation method is simple, does not require chemical treatment, is easy to industrialize, is suitable for large-area applications, and has high practical value and good anti-ice and snow effect.

Description

technical field [0001] The invention relates to a hydrophobic anti-ice and snow coating of a fluorosilicone acrylate copolymer and a coating preparation method, belonging to the technical field of hydrophobic anti-ice and snow coatings and applications. Background technique [0002] Anti-icing is a worldwide problem. Countries and regions prone to ice disasters and snow disasters, such as Canada, the United States and Northern Europe, have established specialized research institutions to conduct a lot of research on solving the problem of icing. At present, four deicing methods are usually used at home and abroad: mechanical deicing, spraying anti-icing agent, heating deicing and natural passive deicing. The first three methods have many problems such as high work intensity, low efficiency, polluting the environment, and high energy consumption; natural passive deicing is to reduce the adhesion of ice to the surface of the substrate and the surface The amount of ice covered...
