Description

Technical Field

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

[0002] With the rapid development of modern industry, modernization, high-speed, efficient transportation, and environmental protection are attracting increasing attention. Marine coatings are also undergoing continuous upgrading. The natural corrosion rate of steel in seawater is 0.1 mm / year. Marine growth attached to the exterior of a ship's bottom can also reduce navigation speed, increasing fuel costs and the cost of removing marine growth. Therefore, ship bottom coatings must possess excellent seawater resistance and antifouling properties. Antifouling paint is a key product in marine coatings. Upon contact with seawater, the antifouling agent ions or molecules contained in the paint film gradually dissolve into the seawater, forming a thin layer of toxic solution over ten microns thick on the paint film surface. The toxic ions or molecules in the solution repel or kill larvae and spores of marine organisms that attempt to attach to the paint film, thereby preventing fouling. Commonly used organotin compounds such as tributyltin fluoride, tributyltin oxide, and triphenyltin fluoride, as well as antifouling agents such as DDT, can cause biological mutations, endanger the stability of the marine food chain, disrupt 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 dome, it will interfere with the sonar's reconnaissance performance. These will greatly weaken the warship's combat effectiveness. It can be seen that marine biofouling is extremely harmful to ships. Methods to prevent marine biofouling include antifouling paint, electrolysis of seawater, ultrasonic antifouling, etc. However, so far, antifouling paint is considered to be the only widely used method, both economically and effectively.

[0004] Existing antifouling coatings have the following disadvantages: they contain large amounts of organotin compounds such as tributyltin fluoride, tributyltin oxide, and triphenyltin fluoride, which can disrupt the endocrine function of mollusks, induce sexual deformities, cause population degeneration and a sharp decline in numbers, seriously endanger the survival of marine life, and change the marine food chain; Wuxi self-polishing antifouling paint, which does not contain organotin 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 speeds less than 10 knots. A fishing vessel coated with Wuxi self-polishing antifouling paint was operating at sea for nearly ten months, and its bottom was covered with marine organisms. When it was almost stationary, it would be covered with various marine organisms; the application caused significant environmental pollution and had a significant impact on the health of construction workers, causing dizziness, eye discomfort, itchy skin, and even ulcers. Summary of the Invention

[0005] The main purpose of this method is to provide a static environmentally friendly marine ship antifouling coating, which can effectively solve the problems in the background technology.

[0006] To achieve the above purpose, the technical solution adopted by this method is: A static environmentally friendly antifouling paint for marine vessels comprises, by mass percentage, 10-18% of special acrylic resin, 18-20% of lime rosin, 7-8% of red iron oxide, 15-18% of special zinc oxide, 3-4% of organic bentonite, 1-2% of fumed silica, 10-15% of nano silver liquid, 3-10% of titanium alloy nano slurry, 15-20% of xylene, and 10-20% of cuprous oxide.

[0007] Preferably, the cuprous oxide is 500 mesh, the red iron oxide is 800 mesh, the particle size of the titanium alloy nano-slurry is 10-30 nm, the nano-silver liquid is nano-silver particles, and the particle size of the nano-silver particles is 5-20 nm; and the special acrylic resin is ETERAC7602.

[0008] Preferably, the method comprises the following steps: S1: Prepare equipment for coating preparation: including high-speed disperser and ultrasonic disperser; S2: Dispersion of lime rosin and xylene: Add lime rosin and xylene according to the corresponding mass percentage into a high-speed disperser for dispersion for 30 minutes; S3: Treatment of nanosilver solution: Add the nanosilver solution according to the corresponding mass percentage into an ultrasonic disperser for ultrasonic dispersion treatment, and the ultrasonic dispersion time is 15 minutes; S4: Mixing treatment: Pour the nanosilver liquid after ultrasonic dispersion treatment into a high-speed disperser filled with lime rosin and xylene for dispersion treatment, the dispersion time is 15 minutes, after the dispersion is completed, add titanium alloy nano slurry according to the corresponding mass percentage and continue to disperse for 15 minutes, then add fumed silica according to the corresponding mass percentage and disperse at high speed, the dispersion time is 5 minutes, then add organic bentonite according to the corresponding mass percentage and disperse, the dispersion time is 10 minutes, then add special acrylic resin according to the corresponding mass percentage and disperse at high speed, the dispersion time is 10 minutes, finally add special zinc oxide, iron red powder and cuprous oxide according to the corresponding mass percentage and disperse at high speed, the dispersion time is 10 minutes, thereby completing the preparation of static environmentally friendly marine ship antifouling coating.

[0009] Preferably, the speed of the high-speed disperser in step S2 is 300 r / min.

[0010] Preferably, the power of the ultrasonic disperser is 800W and the frequency is 15kHz.

[0011] Preferably, the speed of the high-speed disperser for processing the nano-silver liquid, lime rosin and xylene is 300 r / min, the speed of the high-speed disperser for processing the fumed silica is 600 r / min, the speed of the high-speed disperser for processing the organic bentonite is 300 r / min, the speed of the high-speed disperser for processing the special acrylic resin is 600 r / min, and the speed of the high-speed disperser for processing the special zinc oxide, iron ore red powder and cuprous oxide is 600 r / min.

[0012] Compared with the existing technology, this method has the following beneficial effects: This method uses the added nano silver liquid, which is one of the materials with the best killing and inhibiting effects on microorganisms internationally recognized, especially in water. The sterilization effect is more significant, and it is non-toxic to the human body, safe and environmentally friendly. The added titanium alloy nano slurry has a ratio of the number of surface atoms to the total number of atoms that increases significantly as the particle size decreases. The surface tension and surface film tension of the titanium alloy nano slurry particles also increase, 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 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. This 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 biocompatible metal and can be used in medicine to make titanium. Artificial bone implants, with this titanium alloy nano slurry particles have excellent resistance to alternating heat and humidity, 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 seawater, 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 rosin slowly dissolves, the surface of the paint film continues to reveal a fresh surface. After testing, it was found that no marine organisms attached when the paint was hung in the Beihai and Ganzhou Island for 12 months and 2 months respectively in a stationary state.

[0021] A static environmentally friendly marine ship antifouling coating comprises the following steps: S1: Prepare equipment for coating preparation: including high-speed disperser and ultrasonic disperser; S2: Dispersion of lime rosin and xylene: Add lime rosin and xylene according to the corresponding mass percentage into a high-speed disperser for dispersion, the dispersion time is 30 minutes, and the speed of the high-speed disperser is 300 r / min; S3: Treatment of nanosilver solution: Add the nanosilver solution according to the corresponding mass percentage into an ultrasonic disperser for ultrasonic dispersion treatment.

[0022] The static environmentally friendly marine antifouling coating prepared by this method is compared with the performance of common marine antifouling coatings on the market. The static environmentally friendly marine antifouling coatings prepared by this method are recorded as Examples 1 and 2, and the marine antifouling coatings on the market are comparative examples. Common marine antifouling coatings on the market are coatings containing organic tin such as tributyltin fluoride, tributyltin oxide and triphenyltin fluoride and pesticides such as DDT. The following is a comparison table: This shows that the static environmentally friendly marine ship antifouling coating prepared by this method has excellent performance.

[0023] Depend on Figure 5-6 As shown, iron plates coated with and not coated with the coating prepared by the method 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 prepared by the method.

[0024] This method uses the added nano silver liquid, which is one of the materials with the best killing and inhibiting effects on microorganisms recognized internationally, especially in water. It has a more significant sterilization effect and 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 surface and surface film tension of the titanium alloy nano slurry particles also increases, 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 they are very easy to combine with other atoms and tend to be stable, with high chemical activity, namely the surface effect. At the same time, when the size of the 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. 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 heat and humidity, mold and salt spray, etc. The added special zinc oxide has a good killing effect on Staphylococcus aureus and the like. 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 dissolve 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. After testing, such as Figure 3-4 As shown, there was no marine growth when the boat was stationary in the North Sea and Naozhou Island for 12 months and 2 months respectively.

[0025] Although embodiments of the present method have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present method, and the scope of the present method is defined by the appended claims and their equivalents.
