The organic coating is one of the techniques which are simple, effective and most widely used in all corrosion protection measures, and can provide a physical barrier between the corrosive medium and the metal matrix, thereby effectively blocking the corrosion of the corrosive medium to the metal matrix. Corrosion mostly begins at the contact interface between the aqueous medium and the material, however, the organic coating is affected by solvent evaporation during the preparation process and mechanical external forces during use, resulting in defects on the surface of the coating, leading to intrusion of the corrosive medium into the interior of the coating, causing failure of the coating. Therefore, there is a need to increase the repellency of the coating to aqueous media, reduce the contact area and contact time of the coating with corrosive media, and improve the corrosion resistance of the coating.

the preparation process of environment friendly superhydrophobic clay includes dissolving natural sepiolite in solvent, and modifying with surface modifier to obtain hydrophobic clay; wherein the surface modifier is monoalkoxy titanate; the monoalkoxy titanate can be KR-TTS, TL-411A, kr-12, KR-38S and the like.
The raw material is dissolved by natural sepiolite through a solvent; wherein the solvent is absolute ethyl alcohol, and the weight ratio of the natural sepiolite to the absolute ethyl alcohol is 1:5-1:20.
The surface modifier is dissolved by tetraethyl orthosilicate and then carries out modification treatment on the raw materials; the volume ratio of the monoalkoxy titanate to the tetraethyl orthosilicate is 1:10-10:10.
The weight ratio of the tetraethyl orthosilicate to the absolute ethyl alcohol is 1:2-1:10.
and (3) drying the raw materials, dissolving the raw materials in a solvent, adding a surface modifier at room temperature after dissolving, carrying out ultrasonic treatment, and stirring and modifying treatment to obtain the super-hydrophobic clay.
The green environment-friendly superhydrophobic clay obtained by the method is light yellow powder, the modified clay powder has a higher water contact angle (greater than 150 degrees) and a lower sliding angle (less than 5 degrees), the powder cannot be soaked after being contacted with water drops, and the powder cannot sink after being contacted with an aqueous solution.
An application of green environment-friendly super-hydrophobic clay: the green environment-friendly super-hydrophobic clay is applied to being used as an organic resin additive.
The application of the super-hydrophobic clay and the organic resin mixed on the surface of the substrate to form an organic coating serving as an anti-corrosion coating of the substrate.
The mass content of the green environment-friendly super-hydrophobic clay in the organic resin is 2-15%; wherein the organic resin is epoxy resin, acrylic resin, polyurethane resin or amino resin.
The green environment-friendly super-hydrophobic clay powder has good application prospect in metal corrosion prevention, is simple to prepare and low in cost, and can remarkably improve the hydrophobicity, toughness and corrosion resistance of the organic coating.
Compared with the prior art, the invention has the following beneficial effects:
the invention utilizes monoalkoxy titanate to carry out surface treatment on sepiolite powder, thus obtaining the functional sepiolite with super-hydrophobic property.

Detailed Description
The following description of the embodiments of the present invention is further provided in connection with the accompanying examples, and it should be noted that the embodiments described herein are for the purpose of illustration and explanation only, and are not limiting of the invention.
Unless defined or otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. In addition, any method and material similar or equivalent to those described may be used in the methods of the present invention.
The invention uses sepiolite which has high theoretical specific surface area, porosity and surface activity, has good adsorption performance on organic or inorganic ions and is easy to carry out surface functionalization treatment as clay, and then uses titanate to modify the sepiolite to obtain modified sepiolite, which has super-hydrophobic performance, and can obviously improve the hydrophobic performance of a resin coating after being combined with organic resin. Meanwhile, the modified sepiolite still keeps the original whisker structure, and can be used as nano filler to effectively fill micropores of the organic coating, so that the mechanical property of the organic coating is obviously improved, and the protective property of the organic coating is further improved. Furthermore, the sepiolite modified composite coating has multiple performances of toughening, hydrophobicity, corrosion resistance and the like, and has a wide application range.
Example 1
1) Preparation of modified sepiolite:
(1) weighing 3.2g of sepiolite raw material, placing the sepiolite raw material in a vacuum drying oven, vacuumizing, and drying at 120 ℃ for 24 hours;
the natural sepiolite powder is fibrous magnesium-rich silicate clay mineral, the fiber length can reach several micrometers, and the natural sepiolite powder has rich reserves in the nature, is environment-friendly and nontoxic. The outer surface of the sepiolite has a large number of silanol groups, so that the difficulty of hydrophobic modification is low; the sepiolite has a special crystal structure inside, so that the sepiolite has a large specific surface area and high surface activity, has stronger adsorptivity and excellent filling property, and is suitable for serving as a pigment and filler of an organic coating.
(2) Dissolving the sepiolite in 35g of absolute ethanol solvent, mechanically stirring for 24 hours, and keeping the temperature at (25+/-2);
(3) 2mL of titanate (KR-TTS) is weighed and dissolved in 5mL of tetraethyl orthosilicate, after ultrasonic treatment is carried out for 30min, the solution is poured into the sepiolite which is mechanically stirred in the step, and stirring is continued for 24h;
(4) the stirred product was removed and ground, sieved, placed in a sealed bag and then kept in a dry dish (see figures 1, 2 and 3).
2) Application of modified sepiolite:
weighing 10g of E44 epoxy resin and 0.3g of the modified sepiolite, heating and stirring for 24 hours in a water bath kettle with the temperature of 50 ℃, adding 8g of low molecular polyamide and 2g of absolute ethyl alcohol, uniformly stirring, putting into a vacuum drying oven, smearing on the surface of Q235 carbon steel with the model specification of 20 multiplied by 40mm after bubbles are removed completely, and finally drying for 48 hours in a drying oven with the temperature of 60 ℃.
And (3) performing performance test on the modified sepiolite and the composite organic coating obtained by the preparation method:
1) Scanning Electron Microscope (SEM) images of unmodified sepiolite and modified sepiolite:
as can be seen from fig. 1, (a) is modified sepiolite and (b) is unmodified sepiolite, the most obvious difference between the two is that the internal pore space of the structure is changed, the needle-shaped structure of the modified sepiolite is increased and the whole aggregate is reduced after modification due to the change of the morphology of the modified sepiolite.
2) Transmission Electron Microscopy (TEM) of unmodified sepiolite and modified sepiolite:
as can be seen from fig. 2, fig. a is a modified sepiolite, the original needle-like structure of the sepiolite is not changed obviously, but after modification, the original needle-like structure of the sepiolite begins to become large, the surface begins to become rough from the original smoothness, and aggregation occurs, so that the pores of the internal structure are reduced obviously.
3) Infrared spectra (FTIR) of unmodified sepiolite, modified sepiolite:
as can be seen from FIG. 3, the results of the patterns of unmodified sepiolite (a) and modified sepiolite (b) are almost identical, the only difference being 2925 and 2853cm -1 And the characteristic peaks of the two are saturated C-H characteristic peaks of titanate (C). It can thus be seen that the modified sepiolite has been successfully grafted with a titanate surface modifier and that the overall surface energy is reduced, thereby greatly increasing the hydrophobicity.
4) Hydrophobicity comparison of modified sepiolite versus unmodified sepiolite:
as can be seen from the comparison of the two graphs a and b in FIG. 4, the sepiolite powder after the hydrophobic treatment has excellent hydrophobicity, the contact angle of water drops and the powder is more than 150 degrees, the super-hydrophobic standard is achieved, and the unmodified sepiolite is very soluble in water; pouring the powder into a beaker containing deionized water, the modified sepiolite powder was found to float entirely above the water surface, while the unmodified sepiolite powder rapidly precipitated under water. After being placed for 1 month at room temperature, the modified sepiolite powder still floats on the water surface and does not sink, so that the modified sepiolite powder can be proved to have super-strong hydrophobicity.
5) Tensile strength of the modified epoxy coating versus the unmodified epoxy coating:
the two ends of each sample are fixed on a tensile testing machine, the tensile stress is slowly applied, the tensile stress is gradually increased along with the increase of time, the sample stops when the sample is broken, and the tensile stress value and the tensile distance of the sample at the moment are recorded.
As shown in the curve (b) of fig. 5, after 10% of modified sepiolite powder is added into the epoxy resin, the maximum stretching amount of the epoxy resin is slightly reduced, but the stretching distance is obviously improved, and the epoxy resin breaks after being 8mm higher than that of the common epoxy resin (the curve (a) of fig. 5), which shows that the sepiolite obviously improves the flexibility of the epoxy resin, and can effectively improve the brittleness property of the epoxy resin, so that the epoxy resin can bear the influence of mechanical external force.
6) Electrochemical impedance test of modified and unmodified epoxy coatings:
NaCl solution with the concentration of 3.5% is used as electrolyte, a saturated calomel electrode is used as a reference electrode, a carbon rod is used as a counter electrode, the test amplitude is 20mV, and the test frequency is 10 -2 Hz-10 5 Hz, electrochemical impedance testing was performed using a partat p4000+ electrochemical workstation (see fig. 6a and 6 b).
After soaking for 7 days, the impedance of the modified epoxy coating can reach 10 6 Ω·cm 2 (fig. 6 (a)) or more, has a certain protective ability. While the unmodified epoxy coating is reduced to 10 4 Ω·cm 2 (FIG. 6 (b)) the protection capacity is essentially completely lost.
Example 2
The difference from example 1 is that sepiolite surface treatment agent is different, and modified organic resin is different:
1) Preparation of modified sepiolite:
(1) weighing 4.6g of sepiolite serving as a raw material, placing the sepiolite into a vacuum drying oven, vacuumizing, and drying at 130 ℃ for 12 hours;
(2) dissolving the sepiolite in 25g of absolute ethanol solvent, mechanically stirring for 20h, and keeping the temperature at (25+/-2);
(3) weighing 5mL of titanate (TL-411A), dissolving in 6mL of tetraethyl orthosilicate, carrying out ultrasonic treatment for 40min, pouring the solution into the sepiolite which is being mechanically stirred, and continuously stirring for 36h;
(4) taking out the stirred product, grinding, sieving, placing in a sealed bag, and then placing in a drying dish for storage.
2) Preparation of the composite organic coating:
8g of polyurethane resin and 0.4g of the modified sepiolite prepared by the method are weighed, heated and stirred for 24 hours in a water bath kettle with the temperature of 50 ℃, 10g of polyurethane resin curing agent and 6mL of absolute ethyl alcohol are added, the mixture is stirred uniformly and then placed in a vacuum drying oven for vacuum treatment, after bubbles are removed completely, the mixture is smeared on the surface of Q235 carbon steel with the model specification of 20 multiplied by 40mm, and then the mixture is placed in an oven with the temperature of 80 ℃ for 36 hours.
The obtained toughened organic coating prepared by adding the modified sepiolite has the advantages of improved compactness, more uniform thickness and composition, more excellent compliance with a metal matrix and improved original brittleness property of pure epoxy resin; the nano-particle hydrophobization treatment ensures that the whole anti-corrosion performance is further and the protection of the metal matrix is more excellent.
It will be understood that various modifications, substitutions, simple combinations, etc. may be made by those skilled in the art without departing from the scope of the invention as set forth in the appended claims.
