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-borne cable anti-icing paint containing water-borne perfluoroalkyl fluorocarbon emulsion, which comprises the following raw materials in percentage by weight: 58 to 62 percent of aqueous perfluoroalkyl fluorocarbon emulsion, 1.5 to 2.5 percent of water-borne polytetrafluoroethylene emulsifying wax, 15 to 20 percent of water-borne color paste, 0.1 to 0.5 percent of pH regulator, 1 to 2 percent of amino resin cross-linking agent or water-borne polyurethane cross-linking agent, 0.1 to 0.2 percent of antiseptic preservative, 1 to 1.2 percent of cellulose and the balance of deionized water, wherein the water-borne color paste is the mixture of the water-borne color paste with one color or the water-borne color paste with more than two colors. The water-borne cable anti-icing paint of the invention is big in water repellent angle, low in surface energy, excellent in water repellent and oil repellent properties, safe and environment-friendly, can firmly adhere to the surface of a cable in a low temperature and cold environment and is obvious in 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,...
