Abstract

The invention discloses transformer preservative paint which comprises the following raw materials in parts by weight: 30-50 parts of high-hardness aqueous acrylic resin, 20-28 parts of polyurethane, 15-25 parts of red lead, 1-3 parts of phenyl silicon oil, 5-8 parts of diethylenetriamine, 3-5 parts of ethyl acetate, 4-8 parts of triphenyl phosphate, 2-3 parts of zinc borate, 5-10 parts of packing, 1-2 parts of a defoaming agent, 2-3 parts of a dispersing agent, 2-4 parts of a preservative, 4-8 parts of houttuynia cordata, 1-3 parts of a thickening agent and 10-20 parts of deionized water. The transformer preservative paint disclosed by the invention is relatively small in raw material quantity, relatively low in cost, relatively simple in preparation process and very good in temperature resistance and corrosion resistance.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to a transformer anticorrosion paint and a preparation method thereof. Background technique [0002] In the production process of smelting and chemical industries, the emission of smoke and dust is relatively large, which has a serious corrosion effect on the metal shell of large transformers, especially the damage to the weak part of the transformer - the radiator. Corrosion has become a major hidden danger to the operation safety of large transformers, which affects the service life of transformers. It is economical and technically feasible to use paint protection for large-scale transformers in operation. The operation is relatively simple and can be carried out by taking advantage of power failures. Therefore, anti-corrosion paint is an important factor in transformer anti-corrosion. Contents of the invention [0003] The invention provides a transformer anti...
