With the continuous consumption of global resources, shallow sea resources cannot meet the development of national economy, the research of each country is continuously expanded to the deep sea field, the deep sea environment is worse, and the requirement on the anti-corrosion performance of the material is higher. Corrosion problems of metals in marine installations are one of the most important industrial problems, which are closely related to safety problems, environmental problems and huge economic losses.
Therefore, it is very important to develop an effective corrosion protection method suitable for metals in marine environments, especially in deep sea environments, and the application of corrosion protection paint is one of the most widely used and effective protection methods in marine environments. However, during the curing of the coating, there are inevitably tiny cracks and defects in the coating, which may accelerate penetration of corrosive particles into the substrate, initiating the corrosion reaction in a short period of time. Therefore, adding two-dimensional materials such as graphene, boron nitride, layered hydrotalcite and the like into the coating is an effective strategy for improving the corrosion resistance of the organic coating.

Transmission electron microscopy analysis: transmission electron microscopes, commonly referred to simply as TEMs, are available in the form of a model numberThe accelerating voltage of the transmission electron microscope of Talos F200x is set to be 50-100 kV. The invention mainly utilizes TEM to oxidize graphene GO and Ti 3 C 2 T x And GO-Ti 3 C 2 T x Characterization analysis of the surface morphology of (C) and of GO-Ti 3 C 2 T x Synthesis and characterization of nanoplatelets:
TEM records GO, ti 3 C 2 T x And GO-Ti 3 C 2 T x The surface morphology of the nanoplatelets. As shown in fig. 1 (a), GO exhibits a flaky and transparent structure. For Ti 3 C 2 T x (as shown in FIG. 1 (b)), the freshly exfoliated sheets show a rough image. Due to GO and Ti 3 C 2 T x Ti-O-C interaction between, synthesized GO-Ti 3 C 2 T x The transparency of the flakes decreased and the nanoplatelets were rougher (as in FIG. 1 (c)), indicating GO-Ti 3 C 2 T x Successful synthesis of nanoplate hybridization. Furthermore, from the HAADF image (fig. 1 (d)), the C, O and Ti element contents were 52.25at.%, 34.89at.% and 12.86at.%, respectively.
And (3) surface morphology observation: the fracture surface of the prepared coating was recorded using a field emission scanning electron microscope (FE-SEM, S4800). In addition, a scanning electron microscope (SEM, FEI quanti FEG 250) was used to observe the corrosion morphology of the sample surface.
The structure of the coating: in order to study the dispersibility and compatibility of the nanofiller in the epoxy resin, pure epoxy resins EP, graphene oxide/epoxy resin (GO/EP), ti were observed by SEM 3 C 2 T x EP and GO-Ti 3 C 2 T x Cross-sectional image of/EP, the results are shown in fig. 2. As shown in fig. 2 (a), the cross-sectional morphology of the pure epoxy EP is rough with some holes and cracks due to the rapid evaporation of the solvent during the curing of the coating. Adding graphene oxide GO and Ti into epoxy resin 3 C 2 T x After that (FIGS. 2 (b) and (c)), the number of pores was reduced, indicating that graphene oxide GO and Ti 3 C 2 T x The flakes can significantly improve the compactness of the coating. In addition，GO-Ti 3 C 2 T x the/EP showed a cross-sectional morphology similar to that of a flake with few defects observed (FIG. 2 (d)), indicating GO-Ti 3 C 2 T x The nano sheet can be well crosslinked with the epoxy resin matrix, and the compactness of the coating is improved, so that the composite coating has excellent physical barrier property.
To evaluate the adhesion strength of the coating and the substrate in a severe environment, a pull-out test was used. Fig. 3 shows the relevant values of adhesion strength after immersion in 3.5wt.% NaCl solution at 1atm and 5 MPa. It can be clearly seen that the adhesion strength of pure EP after 8 days of immersion in 3.5wt.% NaCl solution of 1atm was 6.82MPa, and the adhesion strength after immersion in a 5MPa environment was reduced to 2.78MPa. The addition of nanofillers to the epoxy resin can effectively improve the adhesive strength of the coating to a certain extent. GO, ti 3 C 2 T x And GO-Ti 3 C 2 T x After the nano-sheet is incorporated into the epoxy resin matrix, the adhesive strength is respectively improved to 7.23MPa (GO/EP) and 7.19MPa (Ti) 3 C 2 T x EP and 7.58MPa (GO-Ti) 3 C 2 T x /EP). In addition, the adhesive strength of the coating is obviously enhanced after the coating is soaked in a 5MPa environment. Compared with pure EP, the adhesive force strength of the composite coating is increased by 64 percent (GO/EP) and 72 percent (Ti) 3 C 2 T x EP) and 113% (GO-Ti 3 C 2 T x /EP). Thus, GO-Ti is added to the epoxy matrix 3 C 2 T x Can effectively prevent the coating from falling off from the Q235 steel, thereby ensuring that the composite coating has good protective capability.
Electrochemical testing: the corrosion performance of the coated Q235 electrode of the above examples was evaluated by the present invention through a Gamry electrochemical workstation. Electrochemical measurements were performed at a hydrostatic pressure of 5MPa and at 1 standard atmospheric pressure (atm), respectively, on the basis of a conventional three-electrode system. A Q235 electrode, a platinum electrode, and a solid Ag/AgCl electrode were used as the working electrode, the counter electrode, and the reference electrode, respectively. Open Circuit Potential (OCP) testing was performed for 60 minutes to reach steady state prior to each measurement. Then, by setting 10 -2 ～10 5 Electrochemical Impedance Spectroscopy (EIS) measurements were performed at a frequency range of Hz and a sinusoidal disturbance of 20 mV. Three replicates were performed under the same conditions.
Electrochemical Impedance Spectroscopy (EIS) is an effective method for detecting the corrosion resistance of a coating. FIG. 4 shows pure EP, GO/EP, ti 3 C 2 T x EP and GO-Ti 3 C 2 T x Bode plot of EP soaked in 3.5wt.% NaCl solution at 5MPa for 1h, 2day, 4day, 8 day. In the Bode-impedance plot, |Z| | 0.01Hz The higher the value of (2) is, the stronger the corrosion resistance is. As shown in FIG. 4 (a 1), the pure EP coating has a value of |Z| 0.01Hz After 1 hour of soaking, 9.61×10 8 Ωcm 2 Then drops sharply to 6.22×10 after 8 days of soaking 5 Ωcm 2 . For GO/EP, |Z| 0.01Hz At the initial stage 1.04×10 9 Ωcm 2 Soaking for 8 days, and then cooling to 3.33X10 7 Ωcm 2 。Ti 3 C 2 T x the/EP shows a similar variation as the GO/EP, initial |Z| 0.01Hz 8.99X10 8 Ωcm 2 After 8 days, it drops to 4.26X10 7 Ωcm 2 . For GO-Ti 3 C 2 T x for/EP, it exhibits the highest |Z| throughout the test period 0.01Hz Values. its|Z| 0.01Hz Remain at 1.84×10 after 8 days of soaking 8 Ωcm 2 About, the steel shows excellent corrosion resistance and the best protection performance for Q235 steel. In addition, a linear relationship was observed between logZ and logf, with a slope close to-1, indicating typical capacitive performance. And the maximum phase angle decreases with increasing soak time. These results indicate that the corrosive particles penetrate into the coating and destroy the corrosion protection properties of the coating.
For comparison, pure EP, GO/EP, ti were also evaluated 3 C 2 T x EP and GO-Ti 3 C 2 T x Corrosion performance of EP immersed in 3.5wt.% NaCl solution at 1 atm. As shown in FIGS. 5a-d, all of |Z| are extended with the soaking time 0.01Hz All exhibit a decreasing trend. At 3.5wt.% NaCl solutionAfter 1 day of soaking, all coatings showed a higher |Z| 0.01Hz (higher than 10) 8 Ωcm 2 ) Indicating good physical barrier capability at the initial stage. As the soaking time is prolonged, |Z| 0.01Hz Exhibiting a monotonic decreasing trend. For pure EP, |Z| 0.01Hz From 2.94×10 8 Ωcm 2 (1 day) to 5.66×10 6 Ωcm 2 (60 days) indicating a weaker physical barrier property. The nano filler is added into the epoxy resin coating to effectively improve the compactness of the coating, thereby enhancing the barrier effect. GO/ep|Z| 0.01Hz From 1.04×10 9 Ωcm 2 (1 day) to 3.37X10 7 Ωcm 2 (60 days). For Ti 3 C 2 T x /EP，|Z| 0.01Hz After 60 days of soaking, it was lowered to 4.26X10 7 Ωcm 2 . Interestingly, for GO-Ti 3 C 2 T x for/EP, |Z| 0.01Hz Remains at a higher level after 60 days of soaking (1.84×10 8 Ωcm 2 ). These results strongly indicate that GO-Ti 3 C 2 T x EP possesses a strong corrosion resistance.
Surface topography analysis: after 60 days of immersion at 1atm, the coating peeled off the Q235 steel surface, the morphology of the steel being shown in FIGS. 6 a-d. For pure EP coating (fig. 6 (a)), many corrosion products were observed to cover the steel surface, indicating that corrosive particles easily penetrate into the coating and attack the steel. For GO/EP (FIG. 6 (b)), many micron-sized particles and some white films appear on the surface. For Ti 3 C 2 T x The number of microscale particles is reduced by/EP (fig. 6 (c)) compared to GO/EP, and the surface shows many white spots, possibly due to weak attack by corrosive particles. GO-Ti 3 C 2 T x The surface of/EP shows a smooth and clean image (fig. 6 (d)) similar to a freshly polished image with only a small amount of particles.
The invention also provides an application of the water-based anticorrosive paint prepared by the method, and the water-based anticorrosive paint is applied to corrosion prevention of ocean and deep sea environments.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
