Anti-icing laminating membrane

Abstract

The invention discloses an anti-icing laminating membrane. The anti-icing laminating membrane is formed by a base layer, a middle solution bubble cap layer and an outer skin surface layer through bonding, wherein the middle solution bubble cap layer is composed of a middle layer filling material, a low-freezing-point solution and bubble caps, a plurality of bubble caps are embedded in the middle layer filling material, the low-freezing-point solution fills the bubble caps, and the outer skin surface layer and the middle layer filling material are bonded together; the freezing point of the solution in the bubble caps is slightly lower than that of water, stress strain caused by phase change expansion of the low-freezing-point solution in the bubble caps acts on the outer skin, as the expansion stress of the bubble caps to the skin is not uniform and continuous surface stress, non-uniform stress caused by the skin acts on an external icing freezing interface until a defect of the interface is caused, ice is fractured or the adhesion strength of ice is reduced due to the unstability of the freezing interface, then the ice cracks and falls off or is convenient to remove, and therefore, the ice can be conveniently cleaned.

Description

technical field [0001] The invention belongs to the technical field of freezing protection, and in particular relates to an anti-icing coating. Background technique [0002] The phenomenon of icing on the surface of materials widely exists in daily life and industrial fields, such as electric power, aviation, transportation, engineering and other industries. Icing of instruments and equipment will affect the working status of the equipment and reduce its working efficiency. The icing of the aircraft fuselage will affect its flight status, and serious flight safety accidents will occur, resulting in casualties. The icing of power towers will cause power transmission problems, seriously cause disconnection of towers, power system paralysis and huge economic losses. The icing of the EMU chassis suspension system will affect the normal operation of the vehicle and cause serious traffic accidents. [0003] At present, there are mainly two measures to deal with the hazards caus...

Problems solved by technology

However, both measures have certain shortcomings and deficiencies. Chemical ice melting has certain pollution to the environment due to the use of chemical substances to melt ice; while heating ice melting and mechanical deicing methods consume energy and are not economical.

Moreover, deicing after freezing will cause certain hidden dangers. It is very likely that the equipment will be affected by the force of freezing and have serious irreversible consequences or serious accidents.

The disadvantage of the surface coating method is that the use effect is not long-term, the coating life is short, and some hydrophobic materials are not easy to prepare; the method of using low-energy substances to modify the surface of the material also has great limitations. For example, the patent CN102492945A discloses a bionic Anti-icing surface of micro-nano composite structure and preparation method thereof, anti-icing by adding nanostructures on microstructures

The preparation process is complicated and cumbersome, and the temperature and time span achieved have great limitations.
