Problems solved by technology

[0003] Existing anti-icing coatings have limited effects. Although the most researched superhydrophobic coatings have good waterproof and anti-fouling properties, experimental studies have proved (Jiang Xingliang, etc., the application prospect of hydrophobic coatings in power transmission line anti-icing, China Southern Power Grid Technology, 2008, 2(2), 13-18), super-hydrophobic coatings have poor anti-icing ability and short validity period. After there are cracks or the anti-icing microstructure is destroyed, water will easily penetrate into the strands and form knots. Ice, it is difficult to maintain long-term and efficient anti-icing effect
In addition, Chinese patent application CN105283931A introduces an anti-icing method of coating a piezoelectric material on a transmission line, and deicing is performed by causing resistance heating at the outer surface of the cable through the piezoelectric coating, but this method will Significantly increase the line loss of the cable, which is not conducive to the transmission of electric energy

Abstract

The invention provides an anti-ice coating applied to a power transmission line and a preparation method for the anti-icing coating. The anti-ice coating comprises an energy accumulating layer adheredto a wire body and a high-transmittance self-cleaning layer adhered to the energy accumulating layer, wherein the energy accumulating layer comprises 10-60% of a light energy-accumulating absorptionmaterial, 5-50% of a magnetic heating layer and 10-50% of film-forming base stock; the high-transmittance self-cleaning layer comprises 80-95% of a high-transmittance self-cleaning material and 5-20%of a nano enhanced transmittance increasing material. The anti-ice coating is applicable to the power transmission line, has a relatively good anti-icing effect, is long in lasting time, can reduce icing amount on the wire and can delay icing formation; during outdoor application, dust can be effectively avoided; the anti-ice coating is good in adhesion with the wire body, is good in mechanical performance, and is free of a stripping phenomenon during long-term application. The anti-ice coating can be directly prepared on the wire, the operation is simple, wire transformation is not needed, the price is low, and huge economic benefit can be obtained.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to an anti-icing coating applied to a power transmission line and a preparation method thereof. Background technique [0002] Icing on transmission lines seriously threatens the safe operation of global power networks. In Canada, Russia, the United States, Norway, Sweden, the Czech Republic, Japan, the United Kingdom, Finland, Iceland, and the alpine regions of northern and central and western my country, the icing of transmission lines leads to circuit damage and the resulting safety accidents, which seriously affect people's production and life, causing huge economic loss. Therefore, the prevention and control of the line icing disaster is of great significance. [0003] The existing anti-icing coatings have limited effects. Although the most researched super-hydrophobic coatings have good waterproof and anti-fouling properties, experimental studies have proved (Ji...
