Self-repairing anti-icing aluminum stranded wire with composite holes and preparation method of self-repairing anti-icing aluminum stranded wire

Abstract

The invention relates to a self-repairing anti-icing aluminum stranded wire with composite holes and a preparation method of the self-repairing anti-icing aluminum stranded wire, and belongs to the technical field of anti-icing material preparation. According to the self-repairing anti-icing aluminum stranded wire with the composite holes provided by the invention, the uniform porous aluminum oxide film grows on the surface of the aluminum substrate to form small-aperture inner layer holes (for storing a repairing agent for a long time) and large-aperture outer layer holes (for improving the anti-icing performance by increasing the air cushion proportion), the anti-icing aluminum wire with lasting and excellent anti-icing self-repairing performance is prepared by optimizing the aperture and thickness of the large holes (outer holes) and the small holes (inner holes) and filling a low-surface-energy repairing agent in the holes under the action of air pressure, capillary force and surface energy. The anti-icing performance of the aluminum stranded wire in practical application and self-repairing of the anti-icing performance after the aluminum stranded wire is damaged are improved, so that the anti-icing service life of the aluminum stranded wire is prolonged, and the lasting anti-icing performance of the aluminum stranded wire is improved. According to the self-repairing anti-icing aluminum stranded wire with the composite holes, repeated self-repairing of the anti-icing performance is achieved, and meanwhile, the hardness and the abrasion resistance of the film layer are improved.

Description

technical field [0001] The invention belongs to the field of anti-icing material preparation, and relates to a self-repairing anti-icing aluminum stranded wire with composite holes and a preparation method thereof. Background technique [0002] In the current stage, the anti-icing technology is mainly electric current melting ice, which belongs to passive anti-icing. The material prevents or delays the icing on the surface of the wire, and the ice adhesion is low after icing, so that the ice can be easily removed, or the ice can be melted by heat. [0003] However, the energy consumption required for the current ice melting process is large, and the power needs to be cut off during the ice melting process. In addition, uneven ice removal during the ice melting process is prone to tower collapse. The micro-nano structure and low surface energy components of the traditional super-hydrophobic surface are very fragile, and are prone to structural damage under external physical ...

[0003] However, the energy consumption required for the current ice melting process is large, and the power needs to be cut off during the ice melting process. In addition, uneven ice removal during the ice melting process is prone to tower collapse

The micro-nano structure and low surface energy components of the traditional super-hydrophobic surface are very fragile, and are prone to structural damage under external physical effects, resulting in anti-icing failure; in addition, conventional super-hydrophobic surfaces cannot inhibit ice coating in low-temperature and high-humidity environments, such as : Frosting, rime, freezing rain and icing, etc., but because water vapor enters the micro-nano structure and condenses, it loses the anti-icing effect and even gradually develops into a hydrophilic surface, which aggravates icing, which restricts its practical application; at the same time, traditional coatings / paints Poor combination with the substrate leads to short service life and limits related application prospects
