Abstract

The invention discloses an anti-icing coating for power transmission cables. The anti-icing coating is prepared from the following raw materials in parts by weight: 30-45 parts of fluorosilicone resin, 20-30 parts of phosphate modified acrylic emulsion, 5-15 parts of tetrafluoroethylene-ethylene copolymer, 5-10 parts of hollow glass beads, 1-3 parts of a dispersing agent, 0.5-1 part of a levelingagent, 0.1-0.5 part of an antifoaming agent, 1-2 parts of a coupling agent and 20-40 parts of a solvent. The anti-icing coating disclosed by the invention is excellent in hydrophobic property and goodin adhesion property with a power transmission cable, so that the anti-icing property of the cable is excellent.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to an anti-icing coating for power transmission cables and a preparation method thereof. Background technique [0002] Cable icing is formed on the surface of cables due to various meteorological reasons, including temperature, humidity, cold and warm air convection, circulation, and wind speed. According to the formation conditions and degree of damage, there are rime icing, mixed rime icing, and ice icing. Basic types such as rime covered with ice, hoarfrost, and snow. Among them, mixed rime is a composite icing process, first is rain rime, and then rime is a form of alternating ice, which grows faster, seriously endangers the safe operation of transmission lines, and causes huge economic losses. In recent years, people have coated the surface of cables with anti-icing coatings to form a hydrophobic coating, which makes it difficult for ice coating to produce high adhe...
