Embodiment 1

[0032] Hydrophobic monomer methyl acrylate, hydrophobic non-polymeric ionic liquid 1-octyl-3-methylimidazolium tetrafluoroborate, initiator azobisisobutyronitrile, crosslinking agent polyethylene glycol dimethacrylic acid The esters were mixed and stirred evenly at a weight ratio of 1000 / 1000 / 10 / 10. Nitrogen gas was bubbled for 30 minutes to remove oxygen, and evenly coated on an aluminum sheet, and then reacted under heating at 80 oC to form an anti-freezing ionic liquid gel film.

Embodiment 2

[0034] Hydrophobic monomer methyl methacrylate, hydrophobic non-polymeric ionic liquid 1-octyl-3-methylimidazolium tetrafluoroborate, initiator benzoyl peroxide, cross-linking agent polyethylene glycol dimethyl Acrylic esters were mixed and stirred evenly at a weight ratio of 1000 / 1000 / 10 / 10. Nitrogen gas was bubbled for 30 minutes to deoxidize, and evenly coated on the iron sheet, and then reacted under heating at 80 oC to form an anti-freezing ionic liquid gel film.

Embodiment 3

[0036] Hydrophobic monomer butyl methacrylate, hydrophobic non-polymeric ionic liquid 1-octyl-3-methylimidazolium tetrafluoroborate, initiator benzoyl peroxide, cross-linking agent polyethylene glycol dimethyl Acrylic esters were mixed and stirred evenly at a weight ratio of 1000 / 1000 / 10 / 10. Nitrogen gas was bubbled for 30 minutes to remove oxygen, and evenly coated on the copper sheet, and then reacted under heating at 80 oC to form an anti-freezing ionic liquid gel film.

Abstract

The invention relates to an anti-icing ionic liquid gel film and a preparation method therefor. The ionic liquid gel disclosed by the invention consists of a polymer three-dimensional network and free ionic liquid, or consists of a poly ionic liquid three-dimensional network and free ionic liquid. The ionic liquid gel film provided by the invention overcomes the defects of high production cost, poor long residual action, low deicing efficiency, poor stability, poor mechanical strength and difficult extensive preparation existing in a conventional anti-icing material, has the characteristics that the stability is good, the preparation method is simple, the ionic liquid gel film is suitable for extensive preparation, and the mechanical property is excellent, and is a novel long-acting anti-icing material which can be extensively prepared.

Description

technical field [0001] The invention belongs to the field of preparation and application of an anti-icing functional coating, and relates to a method for preparing an anti-icing coating by using an ionic liquid gel film. Background technique [0002] The phenomenon of icing widely exists on cold surfaces in the fields of roads in cold regions, aerospace, cryogenic refrigeration, cryogenic liquid storage and transportation, and so on. Anti-icing coatings are of great significance for reducing traffic accidents caused by icing, preventing damage to communication lines and power grid towers, and improving the heat transfer efficiency of refrigerators and heat transfer equipment. Traditional methods for preparing anti-icing coatings include electrochemical methods, sol-gel methods, and mechanical deicing methods. Due to high production costs, poor long-term performance, low deicing efficiency, and potential safety hazards, the practical application is greatly limited. In recen...
