Abstract

The invention discloses a special anticorrosive paint for a power distribution cabinet shell. The special anticorrosive paint comprises the following raw materials in parts by weight: 15 to 25 parts of methylphenyl silicone resin, 10 to 20 parts of acrylic resin, 12 to 18 parts of epoxy resin, 7 to 14 parts of butyl acrylate, 6 to 9 parts of modified talc, 2 to 4 parts of dioctyl phthalate, 1 to 3parts of fatty alcohol polyoxyethylene ether, 2 to 4 parts of calcium stearate, 1 to 3 parts of boron nitride, 2 to 5 parts of a plant extract, 1 to 3 parts of an ultraviolet absorber, 2 to 4 parts of a leveling agent, 2 to 5 parts of an anti-settling agent, and 20 to 30 parts of a solvent. By controlling the original type and ratio, the anticorrosive paint has low cost, good heat dissipation, excellent heat resistance and excellent salt resistance, and can effectively prolong the service life of a power distribution cabinet.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion paint, and in particular relates to a special anti-corrosion paint for the shell of a power distribution cabinet 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 transformers in operation, and the operation is relatively simple, and it can be carried out by taking advantage of power failure opportunities. [0003] In the prior art, CN103509388A describes an epoxy resin transformer shell antirust paint,...
