Embodiment 1
[0022] A surface treatment agent that generates a red stable rust layer. The components and their mass percentages are: 20% alcohol-soluble phenolic novolac, 2% nickel phosphate, 5% sodium tungstate, 2% sodium silicate, Fe(OH ) 3 5%, Fe 2 o 3 35%, n-butanol 31%, weigh each raw material according to the above ratio, and mix evenly to prepare a surface treatment agent that generates a red stable rust layer.
[0023] Coat the prepared surface treatment agent on the surface of weathering steel bare sample, and let it dry naturally; and accelerate the corrosion in distilled water environment for 10 days (spray distilled water every 3 hours), the surface of weathering steel bare sample without surface treatment The color of the rust layer is uneven, and the rust liquid hangs, and the corrosion rate increases with time; the rust layer on the surface of the bare weathering steel sample coated with the surface treatment agent is uniform red, the rust liquid does not flow, and durin...
Embodiment 2
[0026] A surface treatment agent that generates a red stable rust layer. The components and their mass percentages are: 20% alcohol-soluble phenolic novolac, 3% nickel phosphate, 4% sodium tungstate, 2% sodium silicate, Fe(OH ) 3 6%, Fe 2 o 3 34%, diethylene glycol ether 31%, weigh each raw material according to the above ratio, and mix evenly to prepare a surface treatment agent that generates a red stable rust layer.
[0027] Coat the prepared surface treatment agent on the surface of weathering steel bare sample, and let it dry naturally; and accelerate the corrosion in distilled water environment for 10 days (spray distilled water every 3 hours), the surface of weathering steel bare sample without surface treatment The color of the rust layer is uneven, and the rust liquid hangs, and the corrosion rate increases with time; the rust layer on the surface of the bare weathering steel sample coated with the surface treatment agent is uniform red, the rust liquid does not f...
Embodiment 3
[0029] A surface treatment agent that generates a red stable rust layer. The components and their mass percentages are: 25% alcohol-soluble novolak varnish, 4% nickel phosphate, 4% sodium tungstate, 2% sodium silicate, Fe(OH ) 3 7%, Fe 2 o 3 33%, n-butanol 25%, each raw material is weighed according to the above-mentioned ratio, and mixes evenly, is mixed with the surface treatment agent that generates red stable rust layer.
[0030] Coat the prepared surface treatment agent on the surface of weathering steel bare sample, and let it dry naturally; and accelerate the corrosion in distilled water environment for 10 days (spray distilled water every 3 hours), the surface of weathering steel bare sample without surface treatment The color of the rust layer is uneven, and the rust liquid hangs, and the corrosion rate increases with time; the rust layer on the surface of the bare weathering steel sample coated with the surface treatment agent is uniform red, the rust liquid does...
