preparation example Construction

[0047] The preparation method of the above-mentioned long-acting anti-icing coating for high-pressure facilities comprises the steps:

[0048] 1) Add the formulated amount of hydroxyl-terminated polydimethylsiloxane into the kneader, stir evenly at a speed of 40-60rpm, then add white carbon black, aluminum hydroxide and decabromodiphenylethane in sequence, and adjust the speed 80-120rpm; after heating to 80-120°C, turn on the vacuum to remove air bubbles and small molecular substances, and keep it at 80-120rpm for 1.5-2h to mix the materials in the kneader evenly;

[0049] 2) After the material obtained in step 2) is cooled to room temperature, transfer it to a three-roll machine for grinding until the grinding fineness of the material is below 20 μm, then transfer it to the first stirring tank, and then add No. 120 gasoline of the formula , after initial dispersion at a speed of 40-80rpm, transfer to an emulsifier for repeated emulsification for 3-5 times and mix evenly to ob...

Abstract

The invention provides a long-acting anti-icing coating for a high-pressure facility and a preparation method of the long-acting anti-icing coating. The long-acting anti-icing coating is prepared from the following raw materials in parts by weight: 1) a primer comprising 100 parts of hydroxyl-terminated polysiloxane, 10 to 20 parts of fumed silica, 5 to 15 parts of aluminum hydroxide, 5 to 15 parts of decabromodiphenyl ethane, 2 to 5 parts of a cross-linking agent, 0.1 to 0.5 part of a catalyst, 0.3 to 1.0 part of a coupling agent and 100 to 150 parts of 120# gasoline; and (2) a surface coating comprising 3-10 parts of low surface energy resin, 3-8 parts of nano silicon dioxide, 1-3 parts of a cross-linking agent, 0.1-0.3 part of a catalyst and 50-80 parts of ethyl acetate. According to the long-acting anti-icing coating disclosed by the invention, the primer and the surface coating are combined, so that the long-acting anti-icing coating has excellent super-hydrophobic property and good durability.

Description

technical field [0001] The invention belongs to the technical field of anti-icing materials, and in particular relates to a long-acting anti-icing coating for high-voltage facilities and a preparation method thereof. Background technique [0002] High-voltage power transmission has the advantages of ultra-long-distance, ultra-large capacity and low energy consumption. The construction of high-voltage power grids can not only meet the growing demand for electricity, but also promote the intensive development and efficient utilization of resources, relieve environmental pressure, and save land resources. my country's high-voltage transmission lines stretch for thousands of kilometers and pass through a large number of mountains and hills. Mountains and hills are prone to ice disaster accidents, and it is difficult to repair after ice disaster accidents, which bring huge direct and indirect economic losses to the power system. Therefore, it is very important to research and dev...
