Description

Technical Field

[0001] The method relates to the field of marine ship coatings, and in particular to a static environmentally friendly marine ship antifouling coating. Background Art

[0002] With the development of the national economy and the improvement of people's living standards, the application scope of coatings has been continuously expanded, and the consumption level of coatings has also become one of the important indicators of a country's economic development level. With the rapid development of modern industry, the modernization, high-speed, high-efficiency transportation and environmental protection of ships have attracted more and more attention. Ship coatings are also constantly being updated. The natural corrosion rate of steel in seawater is 0.1mm / a. Marine organisms attached to the outside of the bottom of the ship will also cause the sailing speed to decrease, resulting in increased fuel costs and the cost of removing marine organisms. Therefore, the bottom coating is required to have excellent seawater resistance and Antifouling property. Antifouling paint is one of the important products of ship coatings. After the paint film comes into contact with seawater, the antifouling agent ions or molecules contained in it gradually dissolve into the seawater, forming a thin layer of toxic solution with a thickness of more than ten microns on the surface of the paint film. The toxic ions or molecules in it can repel or kill the larvae and spores of marine attached organisms that attempt to stay on the paint film, thereby preventing fouling. Commonly used organic tin such as tributyltin fluoride, tributyltin oxide and triphenyltin fluoride and antifouling agents such as DDT will cause biological mutations, endanger the stability of the marine food chain, destroy the marine ecological balance, and pose a threat to human health.

[0003] If marine organisms attach to the bottom of a warship, it will affect the speed of the warship. If they attach to the sonar cover, it will interfere with the sonar's reconnaissance performance. These will greatly weaken the warship's combat effectiveness. It can be seen that the fouling of marine organisms is extremely harmful to ships. Methods to prevent fouling by marine organisms include anti-fouling paint, electrolysis of seawater, ultrasonic anti-fouling and other methods. However, so far, anti-fouling paint is considered to be the only widely used method, both economically and effectively.

[0004] Existing antifouling coatings have the following disadvantages: containing a large amount of organic tin compounds such as tributyltin fluoride, tributyltin oxide and triphenyltin fluoride, which can disrupt the endocrine function of mollusks, induce teratogenesis, cause population degeneration and sharp decline in number, seriously endanger the survival of marine organisms, and change the marine food chain; Wuxi self-polishing antifouling paint that does not contain organic tin compounds such as tributyltin fluoride, tributyltin oxide and triphenyltin fluoride and DDT has little antifouling effect on static cross-sea bridges, drilling platforms, wind power foundations, aquaculture cages, submarine pipelines and marine fishing vessels with a speed of less than 10 knots. The bottom of a fishing boat coated with Wuxi self-polishing antifouling paint has been full of marine organisms for nearly ten months of sea operations; when it is almost stationary, it will be covered with various marine organisms; the environment is polluted greatly during construction, especially the health of construction workers, causing dizziness, eye discomfort, skin itching and even ulceration.

[0015] Preferably, the speed of the high-speed disperser in step S2 is 300 r / min.

[0016] Preferably, the power of the ultrasonic disperser is 800 W and the frequency is 15 kHz.

[0018] Compared with the prior art, this method has the following beneficial effects:

[0019] The method adds nano silver liquid, which is one of the materials with the best killing and inhibiting effects on microorganisms internationally recognized, especially in water. It is non-toxic, safe and environmentally friendly to the human body. The ratio of the number of surface atoms to the total number of atoms increases significantly with the decrease of particle size through the addition of titanium alloy nano slurry. The particle surface and surface film tension of the titanium alloy nano slurry also increase accordingly, thereby causing changes in the properties of the particles. The crystal field environment and binding energy of the surface atoms of the titanium alloy nano slurry particles are different from those of the internal atoms, and there are many dangling bonds, and they have different Saturated properties, so it is very easy to combine with other atoms and tend to be stable, with high chemical activity, that is, surface effect. At the same time, when the size of ultrafine particles continues to decrease, under certain conditions, it will cause changes in the macroscopic physical and chemical properties of the material, which is the small size effect. Because the titanium alloy nano slurry particles used are less than 30nm, and the minimum particle size is about 10nm, it causes changes in the physical and chemical properties of the titanium alloy nano slurry particles. In addition, the titanium alloy nano slurry particles are conductive. Titanium alloy has good compatibility with human tissue and blood. It is a biophilic metal and can be used in medicine as titanium. The titanium alloy nano-slurry particles have excellent resistance to alternating humidity and heat, mold and salt spray, etc. The added special zinc oxide has a good killing effect on Staphylococcus aureus, etc. The added cuprous oxide can effectively kill marine attached organisms and has low toxicity to the human body. The Cu+ released by the slightly soluble cuprous oxide enters the larvae or spores of marine organisms and has the effect of agglomerating proteins, thereby killing marine organisms and playing an anti-fouling role. The added lime rosin slowly dissolves in seawater. As the lime rosin dissolves, the nano-silver liquid particles and titanium The titanium alloy nanoparticles, special zinc oxide, cuprous oxide and other environmentally friendly and low-toxic antifouling agents in the alloy nano-slurry gradually dissolve into the sea water, forming a thin layer of environmentally friendly antifouling agents with a thickness of more than ten microns on the surface of the paint film. The nano silver liquid particles, titanium alloy nanoparticles, special zinc oxide and cuprous oxide can repel or kill the larvae and spores of marine attached organisms that attempt to stay on the paint film. As the lime and rosin slowly dissolve, the surface of the paint film continues to reveal a fresh surface. After testing, there was no marine organism attachment when the paint was hung in the North Sea and Naozhou Island for 12 months and 2 months respectively under stationary conditions.

[0048] The static environmentally friendly marine ship antifouling coating prepared by the method is compared with the common marine ship antifouling coating on the market. The static environmentally friendly marine ship antifouling coating prepared by the method is recorded as Examples 1 and 2, and the marine ship antifouling coating on the market is a comparative example. The common marine ship antifouling coating on the market is a coating containing organic tin such as tributyltin fluoride, tributyltin oxide and triphenyltin fluoride and insecticides such as DDT. The following is a comparison table:

[0049]

[0050] This shows that the static environmentally friendly marine ship antifouling coating prepared by this method has excellent performance.

[0051] Depend on Figure 5-6 As shown, iron plates coated with and not coated with the coating of the present invention were placed in the waters of Zhoushan Islands and immersed for 12 and 30 months. It can be seen that no marine organisms attached to the surface of the iron plate coated with the static environmentally friendly marine ship antifouling coating of the present invention.

[0052] The method adds nano silver liquid, which is one of the materials with the best killing and inhibiting effects of microorganisms recognized internationally, especially in water. It is non-toxic, safe and environmentally friendly to the human body. The ratio of the number of surface atoms to the total number of atoms of the added titanium alloy nano slurry increases significantly as the particle size decreases, and the particle surface and surface film tension of the titanium alloy nano slurry also increase accordingly, thereby causing changes in the properties of the particles. The crystal field environment and binding energy of the surface atoms of the titanium alloy nano slurry particles are different from those of the internal atoms. There are many dangling bonds and unsaturated properties, so it is very easy to combine with other atoms and tend to be stable, and it has high chemical activity, that is, surface effect. At the same time, when the size of ultrafine particles continues to decrease, under certain conditions, it will cause changes in the macroscopic physical and chemical properties of the material, which is the small size effect. Because the titanium alloy nano slurry particles used are less than 30nm, and the minimum particle size is about 10nm, the physical and chemical properties of the titanium alloy nano slurry particles change, and the titanium alloy nano slurry particles are conductive, and titanium alloy is compatible with human tissue and blood. Good compatibility, it is a biophilic metal. In medicine, titanium can be used to make artificial bone implants. The titanium alloy nano-slurry particles have excellent resistance to alternating humidity and heat, mold and salt spray. The added special zinc oxide has a good killing effect on Staphylococcus aureus. The added cuprous oxide can effectively kill marine attached organisms and has low toxicity to the human body. The Cu+ released by the slightly soluble cuprous oxide enters the larvae or spores of marine organisms and has the effect of agglomerating proteins, thereby killing marine organisms and playing an anti-fouling role. The added lime rosin slowly dissolves in seawater. It is understood that as the lime rosin dissolves, the nano-silver liquid particles in the nano-silver liquid, the titanium alloy nano-particles in the titanium alloy nano-slurry, the special zinc oxide, cuprous oxide and other environmentally friendly and low-toxic antifouling agents gradually permeate into the seawater, forming a thin layer of environmentally friendly antifouling agents with a thickness of more than ten microns on the paint film. The nano-silver liquid particles, titanium alloy nano-particles, special zinc oxide, and cuprous oxide can repel or kill the larvae and spores of marine attached organisms that attempt to stay on the paint film. As the lime rosin slowly dissolves, the surface of the paint film continues to reveal a fresh surface, and after tests, such as Figure 3-4 As shown, there was no marine growth attachment when the boat was stationary in the North Sea and Naozhou Island for 12 months and 2 months respectively.
