Problems solved by technology

For high-voltage circuits, the main cause of power pollution flashover accidents is that many harmful comprehensive pollutants are deposited on the surface of the insulator, which reduces the surface resistance of the insulator and increases the leakage current under humid conditions, resulting in flashover
[0004] In addition, surface corrosion and salt corrosion will also reduce the surface resistance of electrical equipment and increase leakage current, resulting in leakage, short circuit and power failure accidents

preparation example Construction

[0027] In addition, the preparation method of a kind of above-mentioned insulating protective film paint that the present invention also proposes, comprises the following steps:

[0028] Primary mixing: Weigh the nonafluorobutyl ethyl ether according to the weight percentage and put it into a closed reaction kettle, then add the propylene glycol methyl ether and the D100 solvent oil weighed according to the weight percentage in sequence, at a speed of 50 Stir continuously under the state of -80 rpm until the mixture is homogeneous to obtain the first mixture.

[0029] In the primary mixing step, the purpose of mixing the above three substances to obtain the first mixture is to fully mix the components of the solvent to prevent subsequent insufficient dissolution of the FEVE fluororesin or secondary precipitation.

[0030] Secondary mixing: add the FEVE fluororesin to the first mixture at a speed of 120-180 rpm according to the ratio of the weight percentage, and stir continuousl...

Embodiment 1

[0035] Weigh 5% of FEVE fluororesin, 75% of nonafluorobutyl ether, 6% of propylene glycol methyl ether, and 9% of D100 solvent oil according to weight percentage. Prepare the insulating protective film coating according to the following preparation steps:

[0036] Weigh nonafluorobutyl ethyl ether in a closed reaction kettle according to the weight percentage, then add propylene glycol methyl ether and D100 solvent oil in sequence, and continuously stir at a speed of 60 rpm for 10 minutes to make it evenly mixed;

[0037] Add FEVE fluororesin into the above reaction kettle at the speed of 150 rpm according to the stated ratio, and stir continuously at this speed for 15 minutes;

[0038] After the preparation is completed according to the above steps, it is then homogenized and stirred at a speed of 450 rpm or more for 15 minutes to obtain a uniform and transparent three-proof hard transparent insulating protective film coating for electrical and electrical equipment.

Embodiment 2

[0040] Weigh 8% of FEVE fluororesin, 80% of nonafluorobutyl ethyl ether, 5% of propylene glycol methyl ether, and 7% of D100 solvent oil according to weight percentage. Prepare the insulating protective film coating according to the following preparation steps:

[0041] Weigh nonafluorobutyl ethyl ether in a closed reaction kettle according to the weight percentage, then add propylene glycol methyl ether and D100 solvent oil in sequence, and continuously stir at a speed of 60 rpm for 10 minutes to make it evenly mixed;

[0042] Add FEVE fluororesin into the above reaction kettle at the speed of 150 rpm according to the stated ratio, and stir continuously at this speed for 15 minutes;

[0043] After the preparation is completed according to the above steps, it is then homogenized and stirred at a speed of 450 rpm or more for 15 minutes to obtain a uniform and transparent three-proof hard transparent insulating protective film coating for electrical and electrical equipment.

Abstract

The invention provides an insulating protective film coating and a preparation method thereof, which comprise the following components in percentage by weight: 5-25% of normal temperature self-curingfluororesin, 50-90% of perfluoroalkyl ether, 2-15% of propylene glycol methyl ether and 2-15% of D100 solvent oil. A hard transparent insulating protective film for power and electrical equipment withthe three-prevention function provided by the invention can effectively prevent harmful comprehensive pollutants from adhering to the surface of the equipment and greatly relieve corrosion and salt corrosion on the surface of the equipment. After coating, as a smooth and flat anti-pollution hard insulating film is formed on the equipment, various harmful pollutants are difficult to adhere and accumulate on the equipment, thus keeping the equipment clean for a long time. At the same time, due to its excellent weather resistance, mildew resistance, moisture resistance, salt fog resistance and other three-prevention properties, the insulating protective film coating is also conducive to the long-term stable operation of the equipment.

Description

technical field [0001] The invention relates to an insulating protective film paint and a preparation method thereof, in particular to a three-proof insulating protective film paint and a preparation method thereof which can be applied to electric devices. Background technique [0002] The electric power industry is the basic industry of modern industry. The safe production of electric power is related to thousands of households, economic development and social stability. At present, my country's electric power industry has entered the stage of large power grid, high voltage and high automation. Lightning accidents occur frequently all over the country and have a large impact and serious consequences; accidents often cause multiple lines and multiple substations to lose power, and even cause serious power safety accidents such as system oscillation, power grid collapse, and large-scale power outages. It brings a lot of inconvenience to life and causes serious economic losses ...
