Detailed Description
Referring to fig. 1 and 2, the present invention provides a reinforced coating for steel structure: the steel structure comprises a steel structure 1 and a protective layer 2, wherein the protective layer 2 is coated on the upper surface of the steel structure 1, the protective layer 2 consists of a tin alloy base layer 21, an anti-corrosion inner layer 22, an anti-corrosion outer layer 23 and a fluorocarbon coating layer 24, the anti-corrosion inner layer 22, the anti-corrosion outer layer 23 and the fluorocarbon coating layer 24 are sequentially coated on the upper surface of the tin alloy base layer 21, and the tin alloy base layer 21 is coated on the upper surface of the steel structure 1.
Wherein, the corrosion-resistant inner layer 22 is a KN22 coating layer and has stronger hydrofluoric acid resistance.
Wherein, the corrosion-resistant outer layer 23 is a polytetrafluoroethylene coating layer, and has stronger acid and alkali resistance.
Wherein the coating thickness of the tin alloy base layer 21 is 2.0 μm to 10.0 μm.
Wherein the corrosion-resistant inner layer 22 and the corrosion-resistant outer layer 23 have coating thickness specifications of 5.0 μm to 10.0 μm and 10.0 μm to 15.0 μm, respectively.
Wherein, the coating thickness specification of the fluorocarbon coating layer 24 is 3.0 μm-8.0 μm.
The working principle is as follows: after the coating is coated on the steel structure 1, the stability of coating combination with the steel structure 1 is improved by using a tin alloy base layer 21 with few pores and good initial property as a bottom layer, hydrofluoric acid is used as a common acidic substance in the industry by using an anti-corrosion inner layer 22 with strong hydrofluoric acid resistance and an anti-corrosion outer layer 23 with strong acid and alkali resistance as a bearing layer, the protection property to the hydrofluoric acid can be improved by using the anti-corrosion inner layer 22, the anti-corrosion protection property to external acid and alkali substances can be improved by using the anti-corrosion outer layer 23 with inertia resistance and strong acid and alkali resistance, and the anti-corrosion property to the external acid and alkali substances is improved by using a fluorocarbon coating layer 24 as an outer layer, and the coating has extremely low friction coefficient, can reduce the contact adhesion degree of corrosive substances and reduce the corrosion effect, thereby effectively improving the corrosion resistance of the whole steel structure 1, the service stability and the service life are enhanced.
