Abstract

The invention discloses an ice melting agent for deicing power transmission lines, and a preparation method thereof, and belongs-the technical field of deicing of the power transmission lines. The icemelting agent is prepared from, by weight, 15-20 parts of modified multi-walled carbon nanotubes, 24-28 parts of epoxy resin, 30-35 parts of carbamide, 10-16 parts of sodium acetate, 20-25 parts of 1,2-propanediol, 12-18 parts of glycerol, 5-8 parts of glycerol monolaurate, 6-10 parts of a corrosion inhibitor and 41-45 parts of water. The multi-walled carbon nanotubes are modified, and then are compounded with the epoxy resin, carbamide, sodium acetate and the corrosion inhibitor are added, and all above components synergistically act, so the obtained solid granular ice melting agent has excellent comprehensive performances, still has a high ice melting rate in a low temperature environment, has a freezing point of -35 DEG C or below, has very small damages to roads, electric poles and plants, and can form a hydrophobic film on the surface of the material to protect the material and reduce damages. The ice melting agent plays a great role in the deicing operation of the power transmission lines, is especially suitable for the deicing in outdoor low-temperature environments, and is worthy of promotion.

Description

technical field [0001] The invention relates to the technical field of power transmission line deicing, in particular to a deicing agent for power transmission line deicing and a preparation method thereof. Background technique [0002] With the development of the national power industry, the coverage area and density of the power supply grid are increasing, and the safety of the line has become inseparable from our daily life and work. After entering the winter, most parts of our country experienced rain, snow and freezing weather, and the power transmission and transformation facilities were damaged to varying degrees. In some areas, equipment tripping, disconnection and tower down accidents occurred, resulting in power outages in some areas. my country's transmission lines have suffered thousands of icing disasters in varying degrees. The icing of transmission lines will lead to accidents such as wire galloping, disconnection, tower collapse, insulator flashover, etc., w...
