Abstract

The invention discloses an anti-corrosion wearing resistant coating for a transformer and belongs to the technical field of transformers. The anti-corrosion wearing resistant coating is prepared fromthe following raw materials in parts by weight: 25-35 parts of a hydroxyl acrylic resin, 8-15 parts of a phenolic resin, 8-12 parts of heat conduction packing, 6-9 parts of a calcium sulfate crystal whisker, 1-3 parts of emery powder, 1-2 parts of talcum powder, 2-5 parts of a silane coupling agent, 0.5-2 parts of lauryl alcohol polyoxyethylene, 0.1-0.2 part of methyl sodium silicate, 1-3 parts ofa lubricant and 15-20 parts of an organic solvent. The anti-corrosion wearing resistant coating is excellent in mechanical property, good in acid, alkali and salt mist resistance and long in servicelife.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an anti-corrosion and wear-resistant coating for transformers. Background technique [0002] Transformers are generally installed in the open air, and are affected by wind, sun, rain, snow, hail and other climatic conditions for a long time, which will cause aging, rust and corrosion, especially when the transformers in remote areas are corroded and rusted. If it cannot be repaired or replaced in time, it may lead to failure of power equipment, thus affecting the safe and normal operation of power transmission. [0003] Chinese patent (publication number CN107793808A) discloses a high-temperature-resistant anti-corrosion coating for transformers, including the following components by weight: 40-60 parts of phenolic resin, 15-25 parts of methyl methacrylate, and 20-30 parts of polycarbonate , titanium dioxide 20-30 parts, silicon carbide 10-30 parts, quartz sand 15-30 parts,...
