High-voltage power transmission line ice-covering-proof paint and preparation method thereof

Abstract

The invention discloses high-voltage power transmission line ice-covering-proof paint and a preparation method thereof. The preparation method comprises the following steps: using toluene diisocynate, tridecafluoro-octanol, butyl acetate, organosilicon modified epoxy resin, epoxy resin curing agent, organic solvent, nanographite and carbon nanotubes as raw materials to react and ensure that long-carbon-chain fluoro-alcohol is grafted in the molecular chain of epoxy resin, and adding nanographite and carbon nanotubes in the modified epoxy resin to prepare the paint with good hydrophobicity and thermal conductivity. The paint is mainly used in the coating of the high-voltage power transmission line and the coatings of equipment such as the insulator and the transformer case; and the paint has high coating adhesion, is ice-covering-proof and environmental friendly, has the advantages of corrosion resistance, ultraviolet resistance and aging resistance, and no pollution. Compared with the traditional acrylic paint, the paint has the advantages of simple preparation technology and excellent room temperature curing performance and low temperature curing performance, and is convenient to construct and operate.

Description

technical field [0001] The invention relates to the research field of room-temperature-curable epoxy resin-based functional coatings, in particular to an anti-icing coating for high-voltage transmission lines and a preparation method thereof. Background technique [0002] High-voltage power grid lines are prone to icing under conditions such as rain, snow, and low temperature, resulting in excessive vertical loads on the power grid, followed by collapse of towers, disconnection, and until the overall structure collapses, the power grid is paralyzed. Solving the icing problem quickly, efficiently and economically is one of the major technologies that need to be solved urgently. The use of anti-icing coatings can slow down or avoid the formation of icing through the strong hydrophobic coating attached to the surface of the wire. [0003] From the analysis of the formation mechanism of icing, relying on the hydrophobic surface is effective in delaying the formation of ice circ...
