Problems solved by technology

This flame-retardant spray paint has good temperature resistance, can be used normally at 200°C, and has good quick-drying, uniform paint film, bright color, good weather resistance, and is not affected by temperature and ultraviolet rays. And the flame-retardant spray paint has high adhesion; at the same time, it has excellent dispersibility, and it will not cause problems such as thickening and pigment sedimentation after long-term storage. Clogged nozzle, with excellent stability, but the water resistance is not ideal, and the flame retardancy and aging resistance need to be improved

Abstract

The invention provides an electric power overhaul climbing structure surface protection method, and belongs to the technical field of electric power overhaul auxiliary appliances. The electric power overhaul climbing structure surface protection method comprises the steps of S1, preparing a priming solution, specifically, adding acrylic resin, a coupling agent, a leveling agent and water into a stirrer for stirring, and then filtering and standing; S2, coating the priming solution, specifically, removing impurities on the surface of a base material, coating the base material with the priming solution, and airing until the priming solution is semi-dry, that is, the surface of the priming solution does not flow; and S3, coating protective paint, specifically, coating the protective paint on the base material coated with the priming solution, and airing. The priming solution disclosed by the invention is high in adhesive force, the protective paint is excellent in comprehensive performance and high in adhesive force, a paint film is intact through a cross-cut method test, the water absorption rate is 1.23-1.27%, and excellent waterproof performance is shown; acid and alkali corrosion resistance is achieved, and after the paint is soaked in an acid-base solution, the surface of a paint film is free of wrinkling, bubbles and peeling phenomena; and an aging performance test shows that the gloss loss rate is 15.5-14.8%, the cracking grade is 2, aging resistance is achieved, the performance is stable, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance auxiliary appliances, in particular to a method for protecting the surface of a climbing structure for electric power maintenance. Background technique [0002] With the continuous development of the electric power industry, both towns and villages require regular maintenance, line and equipment replacement, etc. Electric power maintenance is inseparable from climbing structures. Common climbing structures include insulating paint and benches. In order to prolong the service life of these climbing structures, a layer of protective paint is generally sprayed on the surface. However, the existing operation method is to directly spray the protective paint on the base material, only one layer of protection is carried out to the base material, and the paint surface is easy to come off. Moreover, the protective performance of the existing protective paint is not ideal. Under the imme...
