In view of this, the utility model provides a reinforced concrete's protective coating structure that anticorrosive effectual, long service life.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a first corrosion inhibition type epoxy coating layer, an epoxy intermediate paint coating layer and a fluorocarbon finish paint coating layer are sequentially coated on the outer surface of reinforced concrete.
According to the technical scheme, compare with prior art, the utility model discloses a reinforced concrete's protective coating structure, first inhibition type epoxy dope layer, epoxy intermediate coat dope layer, fluorocarbon finish paint dope layer all have the corrosion-resistant effect to guaranteed reinforced concrete's corrosion-resistant effect, improved reinforced concrete's life.
Furthermore, the second corrosion inhibition type epoxy coating layer is coated on the outer surface of the steel bar in the reinforced concrete, so that the steel bar is prevented from being corroded, the service life of the steel bar is prolonged, the first corrosion inhibition type epoxy coating layer can be gradually transferred to the outer surface of the steel bar through the pores of the concrete, double corrosion inhibition protection is performed on the steel bar, and the corrosion prevention effect is improved.
Further, the thickness of the second corrosion inhibition type epoxy coating layer is 50 um.
Further, the thickness of the first corrosion inhibition type epoxy coating layer is 60 um.
Further, the thickness of the epoxy intermediate coat paint coating layer is 120 um.
Further, the thickness of fluorocarbon finish paint layer is 80 um.
Further, the first corrosion inhibition type epoxy coating layer and the second corrosion inhibition type epoxy coating layer are VCI sheet zinc coating layers.

Wherein: 1-reinforced concrete, 2-a first corrosion inhibition type epoxy coating layer, 3-an epoxy intermediate coating layer, 4-a fluorocarbon finish coating layer, 5-reinforcing steel bars and 6-a second corrosion inhibition type epoxy coating layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model discloses reinforced concrete's protective coating structure, 1 surface of reinforced concrete has coated first inhibition type epoxy dope layer 2, epoxy intermediate coat dope layer 3, fluorocarbon finish coat dope layer 4 in proper order. The outer surface of a steel bar 5 in the reinforced concrete 1 is coated with a second corrosion inhibition type epoxy coating layer 6.
The thickness of the second corrosion inhibition type epoxy coating layer 6 is 50 um.
The thickness of the first corrosion-inhibition type epoxy coating layer 2 is 60 um.
The thickness of the epoxy intermediate coat paint layer 3 is 120 um.
The thickness of the fluorocarbon finishing paint layer 4 is 80 um.
The first corrosion inhibition type epoxy coating layer 2 and the second corrosion inhibition type epoxy coating layer 6 can be VCI sheet zinc coating layers.
When the reinforced concrete is used for external protection, firstly, the steel bar to be subjected to anticorrosion protection is subjected to acid pickling and passivation surface treatment, the steel bar is hung by a rope and placed into a VCI sheet zinc coating pool for cold soaking for 5-10 seconds, then the steel bar is conveyed into a drying device through a rail, the steel bar is baked for 20 minutes at 85 ℃, and after detection, the thickness of the VCI sheet zinc coating layer reaches more than 50 microns, and the steel bar is packaged and transported. After the concrete reaches a construction site, when the coating is damaged in the processes of cutting the steel bars and manufacturing the steel reinforcement cage, repairing by using VCI zinc coatings, then pouring the concrete, and after the concrete is poured, sequentially brushing a VCI zinc coating layer of 60 microns, an epoxy intermediate paint coating layer of 120 microns and a fluorocarbon finish paint coating layer of 80 microns on the surface of the concrete.
The utility model discloses a at reinforcing bar surface and reinforced concrete surface coating VCI piece zinc dope layer, can form inhibition protective coating at reinforcing bar surface and concrete surface respectively, have the inhibition, hinder and lose the effect to paint dope layer and fluorocarbon finish paint dope layer in the middle of combining the epoxy, realized compound protective structure, can effectively protect the reinforcing bar, improved reinforced concrete's life. Meanwhile, the fluorocarbon finish paint layer plays a role in decorating and protecting reinforced concrete, has good weather resistance, heat resistance, low temperature resistance and chemical resistance, and has unique non-adhesiveness and low friction, and the epoxy intermediate paint layer is used as a connecting paint, so that the adhesive force and the connecting strength between the first corrosion inhibition type epoxy paint layer and the fluorocarbon finish paint layer are improved, the fluorocarbon finish paint layer is not easy to drop, and the service life is prolonged.
