Abstract

The invention relates to a nanometer coating material, and provides a preparation method of an aluminum-based power transmission line with an anti-icing coating layer. The anti-icing coating layer prepared by a hydrolysis method has a static water contact angle greater than 150 degrees; after the anti-icing coating layer is applied to an aluminum sheet, the icing time can be obviously delayed, andthe icing area can be reduced; when the common aluminum sheet is completely covered with ice after 10 h, the icing area of the coating layer is only 60%; after being abraded, the coating layer stillhas certain anti-icing property; after the anti-icing coating layer is applied to the aluminum wire, the ice removal ability is obviously reduced.

Description

technical field [0001] The invention discloses a method for preparing an aluminum-based transmission line with an anti-icing coating, which belongs to the field of materials and energy, and mainly relates to the problem of icing of transmission lines. The anti-icing ability of aluminum lines can be effectively improved by coating. Background technique [0002] Ice and snow accumulation on transmission lines seriously threaten the safe operation of power and communication networks in cold regions. Line icing often causes major accidents such as downed poles (towers) of transmission lines, disconnection and insulator flashover, which seriously endangers the safe operation of the power system and causes huge economic losses. Therefore, countries all over the world have already carried out extensive research and designed many schemes for anti-icing and deicing. So far, there are many anti-icing and deicing technologies at home and abroad, such as thyristor rectifier ice-melting ...
