Problems solved by technology

[0002] Transmission tower is an important infrastructure for power transmission. Corrosion of transmission tower components is a frequent problem in engineering. It usually requires a lot of manpower and material resources to maintain to ensure the safe operation of the power grid. The key to protecting the corroded transmission tower is to prevent The choice of corrosion paint and the treatment of the rusted surface before painting. At present, the anti-corrosion paint primers used for the protection of rusted iron towers mostly use epoxy zinc-rich paint anti-rust primers, etc., but because the surface energy of the zinc layer is very low, many paints The poor adhesion on its surface directly affects the protective effect of the coating system. In general, it needs to be repainted after repairing with coating paint, which requires the staff to paint the antirust paint many times. Raw material costs and labor costs are increased, and a lot of time is spent. Therefore, it is necessary to develop a new type of coating, which can not only resist the corrosion of the environment on the transmission tower, but also form a higher adhesion with the surface of the transmission tower. Reduce the number of brushing and reduce the cost of painting

Embodiment 1

[0020] Example 1: A method for preparing an anti-rust coating for surface treatment of an electric transmission tower, comprising the following process steps:

[0021] (1) High-speed dispersion of film-forming resin: prepare raw materials, wherein the composition of the anti-rust paint for the surface treatment of transmission towers includes epoxy resin E-44 16%, polyvinyl butyral 7%, zinc phosphate 4%, aluminum tripolyphosphate 4%, zinc borate 2%, flaky zinc powder 35%, organic bentonite 1%, rust conversion agent 5%, solvent 21% and mixed curing agent 5%, then the prepared ring Put the oxygen resin and polyvinyl butyral into the high-speed disperser, turn on the high-speed disperser for high-speed dispersion, and make it into a powdery substance. During the high-speed dispersion, a phosphoric acid-tannic acid composite system is added as a rust conversion agent to control corrosion. The speed of the high-speed disperser is 845r / min, and the control dispersion time is 2min;...
