Problems solved by technology

[0004] At present, there are also some surface treatment reagents on the market, such as rust remover, phosphating solution, passivation solution, etc., the product function is single, the use conditions are harsh, and it is difficult to meet the requirements on site
For example, the existing rust remover is mainly based on strong acid solution, which has a fast rust removal effect, but it does great damage to the iron matrix and is prone to over-corrosion; phosphating

Abstract

The invention relates to an activated rust layer rust converting agent for electric transmission and transformation equipment and a preparation method and application of the rust converting agent and belongs to the technical field of corrosion prevention of special materials. The rust converting agent disclosed by the invention is prepared from the following components in parts by mass: 8-15 parts of phosphoric acid, 1-3 parts of citric acid, 0.5-3 parts of oxalic acid, 0.1-0.5 parts of thiourea, 0.1-0.5 parts of triethanolamine, 1-2 parts of zinc oxide, 5-8 parts of zinc dihydrogen phosphate, 0.1-1 parts of molybdate, 0.1-1 parts of hydrochloride, 0.5-1 parts of emulsifier, 0.5-1 parts of hydrofluoride, 0.5-1 parts of sodium benzoate, and 70-80 parts of deionized water. The components are added to a container according to proportion and mechanically stirred to be uniform, a product can be obtained after the reaction is completed and the solution is transparent and has not impurities, and in use, the rust converting agent can be brushed before a paint is coated. The rust converting agent is reasonable in component design and simple in preparation process, and the obtained rust converting agent has excellent performances, is wide in application scope and is convenient for large-scale production and application.

Description

technical field [0001] The invention relates to an active rust layer rust converter for power transmission and transformation equipment, a preparation method and application thereof, and belongs to the technical field of anticorrosion of special materials. Background technique [0002] Power transmission and transformation equipment is mostly distributed in outdoor environments, and corrosion is very common. Corrosion causes equipment to fail early, causing huge economic losses and waste of resources and energy, and will bring potential safety hazards. Regular inspections of power transmission and transformation equipment in service Anti-corrosion coating to prolong service life. However, the operating environment of anti-corrosion coatings for power transmission and transformation equipment is very harsh. Most of them work in the open air or at high altitudes, surrounded by high-voltage electrical appliances, and the application of electrical and power tools is limited. Hig...
