Problems solved by technology

However, this invention contains more chloride ions, which is more harmful to plants and the environment. After testing, the ice-melting agent has a slow melting rate at low temperatures, poor melting and deicing effects at low temperatures, and cannot be formed on the surface of materials. Protective film, after secondary freezing, the melting effect is even worse

Abstract

The invention discloses an ice melting agent for deicing of an electric pole, and a preparation method thereof, belonging to the technical field of deicing of electric poles. The ice melting agent isprepared from the following components by weight: 2-5 parts of multi-walled carbon nanotubes, 5-10 parts of modified epoxy resin, 28-33 parts of carbamide, 15-20 parts of sodium acetate, 20-25 parts of 1,2-propanediol, 22-28 parts of glycerol, 6-10 parts of a stripping agent, 4-8 parts of a corrosion inhibitor and 35-40 parts of water. According to the invention, epoxy resin is modified and then compounded with the multi-walled carbon nanotubes, and substances such as carbamide, sodium acetate, the stripping agent and the corrosion inhibitor are added; through the synergistic effect of each component, the prepared solid granular ice-melting agent has remarkable ice melting effect, forms a protective film on the surface of the electric pole to prevent the surface of the electric pole from freezing again, suppresses the adhesion between an ice surface and the surface of the electric pole, improves deicing efficiency, and has small damage to roads, the electric pole and the like. When a freezing point reaches -43 DEG C, the ice melting agent can dissolve ice within 224 s or even shorter time, and has good anti-adhesion properties; it only takes 163 s for disconnection of ice cubes from the surface of a test piece; so the ice melting agent has excellent comprehensive performance.

Description

Technical field [0001] The invention relates to the technical field of electric pole deicing, in particular to an ice melting agent for electric pole deicing and a preparation method thereof. Background technique [0002] In winter in our country, electric poles often freeze, which has played a significant role in hindering the maintenance of transmission lines. When the power line is affected and fails, the staff need to climb to the height of the pole to repair the line. If the pole-climbing operation is carried out on a pole with ice layer, it is easy to slip and cause safety accidents. In the prior art, most of the deicing blades are used to directly remove the ice, but because the surface of the electric pole is uneven and rough, the deicing blade cannot effectively remove as much frost as possible, the deicing efficiency is slow, and the deicing quality is not Very well, there is often leakage of ice in part of the pole. In addition, when using the fire roasting method t...
