Embodiment 1

[0025] A kind of preparation method of the anti-icing coating that is applicable to wire and iron tower, concrete preparation method is as follows: solvent xylene, dispersant TEGO Dispers 760W, defoamer TEGO Airex932, leveling agent TEGO 410 and polyurethane modified silicone resin Add to the container one by one, stir and disperse, and then add the pigment zirconia, ruthenium oxide, and cobalt tetroxide nanocomposite powder. The weight ratio of the three nanopowders is 1:1:1. The particle size is 20nm and the specific surface area is 20m 2 / g and filler nano-silica, use a high-speed disperser, stir at a speed of 1000 rpm for 60 minutes, and then use a sand mill or ball mill to disperse and grind to a fineness of 10 μm to obtain a prepared coating. The adjusted paint is filtered with a 200-mesh screen, and the filtered paint is put into a container and sealed.

Abstract

The invention relates to the field of grid anti-icing, and specifically discloses an anti-icing coating suitable for grid equipment, a preparation method and application thereof. The anti-icing coating is composed of the following raw materials in parts by mass: 6-12 parts of pigments, 0.5-2 parts of fillers, 15-32 parts of resins, 47.5-70 parts of solvents, 2-6 parts of dispersants, and 0.1-2 parts of defoamers. 1 part, 1-2 parts of leveling agent; wherein, the pigment is composed of zirconia, ruthenium oxide and tricobalt tetroxide in a mass ratio of 1:1:1. The present invention uses zirconia, ruthenium oxide and cobalt tetroxide nanocomposite powders as pigments, and utilizes the optical synergistic enhancement effect to effectively ensure the energy-gathering effect of the coating under ice-covered conditions, thereby achieving the effects of preventing ice condensation and deicing Effect. The invention has a simple preparation process and low equipment requirements, and the anti-icing coating prepared by using the coating has important application prospects in the field of anti-icing of power grids.

Description

technical field [0001] The invention relates to the field of grid anti-icing, in particular to an anti-icing coating suitable for grid equipment. Background technique [0002] Icing of transmission lines seriously threatens the safe operation of global power networks. In Canada, Russia, the United States, Norway, Sweden, the Czech Republic, Japan, the United Kingdom, Finland, Iceland, and the alpine regions in the north and midwest of my country, the icing of power transmission lines leads to circuit damage and safety accidents, which seriously affect people's production and life. Huge economic loss. With the development of the global power industry, ultra-long-distance power transmission needs to pass through high-cold, high-humidity and high-altitude areas. The problem of icing disasters on lines has become more serious, and the problem of anti-icing in power grids has become more prominent. [0003] Today's main freezing disaster prevention methods and their existing pro...
