Embodiment Construction

[0038] Aqueous perfluoroalkyl fluorocarbon emulsion of the present invention, its raw material is made up of the component that has following mass percent:

[0039] Tetrafluoroethylene 18.6~21.4%,

[0040] Hydroxyethyl allyl ether 2.5~2.8%,

[0041] Hexafluorobutyl methacrylate 4.5~5.0%,

[0042] Octadecyl acrylate 1.0~1.5%,

[0043] Butyl acrylate 3.0~4.5%,

[0044] Vinyl acetate 2.0~2.4%,

[0045] Butyl acetate solvent 26.0~30.0%,

[0046] Initiator 0.06~0.09%,

[0047] Sodium perfluorohexanoic acid sulfonate emulsifier 3.0~4.0%,

[0048] PH regulator 0.07~0.1%,

[0049] Deionized water balance.

[0050] The invention adopts perfluorohexanoic acid sulfonate sodium salt as a fluorine-containing emulsifier, which greatly improves the stability of the emulsion system. The above-mentioned PH regulator is selected from one of 2-amino-2-methyl-1-propanol, ammonia water, sodium carbonate, sodium bicarbonate, sodium acetate, disodium hydrogen phosphate or citric acid, and i...

Abstract

The invention relates to a water-based cable anti-icing coating containing a water-based perfluoroalkyl fluorocarbon emulsion. ~2.5% water-based polytetrafluoroethylene emulsified wax, 15-20% water-based color paste, 0.1-0.5% pH regulator, 1-2% amino resin cross-linking agent or water-based polyurethane cross-linking agent, 0.1-0.2 % of bactericidal preservative, 1-1.2% of cellulose and the rest of deionized water, wherein the water-based color paste is composed of one color of water-based color paste, or a mixture of any two or more colors of water-based color paste. The invention has a large hydrophobic angle, low surface energy, excellent hydrophobic and oleophobic and anti-contamination properties, safety and environmental protection, and can be firmly attached to the surface of the cable in a low temperature and cold environment, so that it has an obvious anti-icing function.

Description

technical field [0001] The invention relates to a water-based perfluoroalkyl fluorocarbon emulsion, a water-based cable anti-icing coating containing the emulsion and a preparation method, belonging to the technical field of emulsion polymerization. Background technique [0002] In the cold outdoor environment of power transmission and transformation cables, especially in snowy and freezing weather, the surface of the power transmission and transformation cables is generally icy, which causes the cable suspension tension to increase exponentially, and the line failure of the cable due to too much icing often occurs. While normal production and life have a greater impact, it also causes greater economic losses to the power sector. According to reports, more than one billion yuan is spent on the maintenance and repair of power transmission facilities in my country every year, and line failures caused by cable icing are one of the maintenance items that often occur. Therefore,...
