Description

Technical Field

[0001] The present invention relates to the technical field of anti-corrosion coatings, and in particular to a dual-curing anti-slip coating and a preparation method and a use method thereof. Background Art

[0002] Anti-corrosion coatings play a vital role in modern industry and construction. Their primary function is to protect metal structures from corrosion and extend their service life. However, in addition to corrosion resistance, the anti-slip properties of anti-corrosion coatings are also crucial, especially in applications such as steel bridges, large-scale machinery and equipment, and marine engineering. These structures often operate in complex environments, facing not only corrosion risks but also mechanical vibration, shock, and long-term loads. Inadequate anti-slip properties of anti-corrosion coatings can lead to a decrease in adhesion between the coating and the substrate, compromising the coating's corrosion protection and even posing safety risks to the structure. For example, in steel bridges, anti-corrosion coatings on high-strength bolted joints require excellent anti-slip properties to prevent slippage and loss of fastening due to vibration or load. In marine engineering, anti-corrosion coatings must not only resist corrosion from seawater but also remain stable under wave impact and tidal fluctuations. Therefore, the anti-slip properties of anti-corrosion coatings are a key factor in ensuring the long-term effectiveness of the coating and the safety of the structure.

[0003] The technological development of anti-corrosion coatings has evolved from traditional coatings to high-performance composite coatings. Currently, anti-corrosion coatings are mainly divided into two categories: inorganic and organic. Inorganic coatings primarily include zinc-based coatings, phosphate coatings, and ceramic coatings. These coatings offer excellent high-temperature and corrosion resistance, are relatively low-cost, and have a long service life. However, inorganic coatings also have some drawbacks, such as relatively weak adhesion, which can lead to coating detachment, especially in humid environments. Furthermore, inorganic coatings lack toughness, making them difficult to withstand complex mechanical stress environments. Organic anti-corrosion coatings use organic compounds such as epoxy resins, polyurethanes, and chlorinated rubber as their primary film-forming materials. These coatings offer excellent adhesion and flexibility, effectively resisting mechanical shock and vibration. For example, epoxy resin coatings are widely used for corrosion protection of steel structures due to their excellent adhesion and chemical stability. However, organic coatings also have some drawbacks, such as poor weatherability and susceptibility to degradation under UV exposure and high temperatures. Some organic coatings also contain volatile organic compounds (VOCs), which pose certain environmental and human health risks.

[0004] To overcome the shortcomings of single-component coatings, researchers have recently attempted to combine inorganic and organic components to develop composite anti-corrosion coatings that combine the advantages of both. These composite coatings aim to combine the high-temperature and corrosion resistance of inorganic coatings with the adhesion and flexibility of organic coatings, thereby providing more comprehensive protection. However, this combination faces numerous technical challenges. First, the poor compatibility of inorganic and organic components can easily lead to delamination or cracking of the coating. Inorganic components are generally hard and brittle, while organic components are more flexible. The significant difference in their physical properties makes it difficult to form a uniform coating. Second, the preparation process of composite coatings is complex, requiring precise control of the ratio of the components and reaction conditions to ensure uniformity and stability. Furthermore, how to improve anti-slip performance while balancing the coating's weather resistance, flexibility, and environmental friendliness remains a key and challenging issue in current research. Therefore, the development of an organic-inorganic hybrid coating is of great significance. Summary of the Invention

[0005] In view of the technical problems existing in the background technology, the present invention provides a dual-curing anti-slip coating and its preparation method and use method, aiming to solve the technical problem that the existing anti-corrosion coating cannot take into account the anti-slip performance, weather resistance and environmental protection.

[0006] In a first aspect, the present invention provides a dual-curing anti-slip coating, which comprises, by weight percentage: 2% to 5% of phosphate acrylate monomer, 3% to 5% of metal-based modified bentonite, 0.05% to 0.2% of emulsifier, 1.5% to 3% of alkali metal oxide solution, 10% to 14% of bisphenol A epoxy acrylate emulsion, 0.5% to 1.2% of film-forming aid, 52% to 58% of zinc powder, 6% to 8% of filler, 0.05% to 0.5% of drying agent and the balance of water.

[0007] Preferably, the metal-based modified bentonite includes any one of lithium-based bentonite, calcium-based bentonite, magnesium-based bentonite, aluminum-based bentonite, and sodium-based bentonite.

[0008] Preferably, the metal-based modified bentonite is lithium-based bentonite.

[0009] Preferably, the alkali metal oxide solution includes any one of lithium oxide solution, potassium oxide solution and sodium oxide solution.

[0010] Preferably, the mass concentration of the alkali metal oxide solution is 30-60 wt%.

[0011] Preferably, the emulsifier is a mixture of anionic emulsifier and nonionic emulsifier.

[0012] Preferably, the mass ratio of the anionic emulsifier to the nonionic emulsifier is (1-1.5):1.

[0013] In the embodiment of the present invention, the anionic emulsifier is sodium lauryl sulfate, and the nonionic emulsifier is OP-10.

[0014] In the present invention, the anionic emulsifier includes but is not limited to the sodium lauryl sulfate listed in the examples, and the nonionic emulsifier includes but is not limited to the OP-10 listed in the examples. Those skilled in the art can routinely select other anionic emulsifiers and nonionic emulsifiers to achieve the emulsification effect.

[0015] Preferably, the film-forming aid includes dipropylene glycol butyl ether.

[0016] Preferably, the filler comprises a mixture of corundum and silicon carbide; the mass ratio of corundum to silicided carbon is 2 to 5:1.

[0017] Preferably, the mass ratio of corundum to silicified carbon is 3:1.

[0018] Preferably, the particle size of corundum is 120-180 mesh; the particle size of silicon carbide is 240-325 mesh.

[0019] Preferably, the solid content of the aqueous bisphenol A epoxy acrylate emulsion is 40-60 wt %.

[0020] Preferably, the drying agent comprises rare earth naphthenate and / or bismuth stearate.

[0021] Preferably, the mass percentage of rare earth naphthenate in the dual-curing anti-slip coating is 0.05% to 0.1%; the mass percentage of bismuth stearate in the dual-curing anti-slip coating is 0.05% to 0.1%.

[0022] In a second aspect, the present invention provides a method for preparing a dual-curing anti-slip coating, comprising the following steps: S1. Mixing a phosphate acrylate monomer and a metal-based modified bentonite, stirring and activating the mixture at 60-80° C., cooling the mixture to room temperature, adding an emulsifier and deionized water, stirring and emulsifying the mixture, and dripping an alkali metal oxide solution into the emulsion. Adjusting the silicate modulus in the emulsion to 3-3.5 and the pH value to 7.0-7.5 to obtain an activated modified bentonite emulsion. S2. The activated modified bentonite emulsion is mixed with the water-based bisphenol A epoxy acrylate emulsion, a film-forming aid, zinc powder and a filler, and then stirred and dispersed to obtain a mixed slurry. A drying agent is then added to disperse the mixture evenly and filtered to obtain a dual-curing anti-slip coating.

[0023] In the present invention, the alkali metal oxide solution controls the hydrolysis equilibrium to adjust the modulus n of the silicate solution to 3-3.5, and condenses to form silica sol, so that the inorganic silicate has good adhesion after drying and forming a film. The alkali metal oxide solution is also used to adjust the pH value of the emulsion so that the emulsion is in a stable state and the zinc powder does not undergo chemical reaction in the system.

[0024] Preferably, in step S2, the stirring and dispersing rate is 2000-3000 rmp.

[0025] Preferably, in step S2, the fineness of the mixed slurry is less than 90 microns.

[0026] In a third aspect, the present invention provides a method for using a dual-curing anti-slip coating, comprising the following steps: The dual-curing anti-slip coating provided by the first aspect of the present invention is applied to a substrate and dried and cured at a temperature of 5-30° C. and a relative humidity of <55%.

[0027] The anti-slip mechanism of the inorganic silicate and organic polymer hybrid material of the present invention is as follows: Inorganic silicates have good fluidity in liquid form and can penetrate into tiny gaps or pores in materials. When they crystallize and solidify, they form solid substances that occupy the original void space. This solid substance has a certain volume and rigidity, which can effectively prevent the occurrence of slip. However, the brittleness of inorganic silicates limits their application in complex stress environments. Therefore, organic polymers are introduced for hybridization. After drying, organic polymers form elastomers similar to rubber or plastic, which have good flexibility and elasticity. This elastomer can undergo elastic deformation when subjected to stress, absorbing and dissipating stress. This elastic deformation ability enables it to better adapt to complex stress environments and further enhance the anti-slip effect.

[0028] Phosphate acrylates are typically synthesized as phosphoric acid diesters or monoesters through an esterification reaction. These phosphates retain a free hydrogen atom and possess a certain degree of acidity. The acidic properties of phosphate acrylates react with silicates. The free hydrogen atoms in the phosphate react with the metal ions in the silicate to form a co-salt of phosphate and silicate. This reaction allows the metal ions to bind to both the organic phosphate and the inorganic silicate, forming an organic-inorganic co-salt structure. Through this reaction, the metal ions form a bridge between the organic phosphate and the inorganic silicate, constructing an organic-inorganic interpenetrating network polymer. The metal ions serve as connecting points, linking the organic phosphate and the inorganic silicate, forming a complex three-dimensional network structure. This structure not only combines the flexibility of organic materials with the rigidity of inorganic materials, but also enhances the overall stability and mechanical properties of the material through the bridging effect of the metal ions.

[0029] The inorganic salt crystallizes and solidifies at room temperature, forming a hard and stable structure. Furthermore, the organic vinyl polymer undergoes oxidation and solidification in air, catalyzed by a metal organic acid salt, imparting excellent flexibility and adhesion to the coating. This dual-curing mechanism combines the advantages of both inorganic and organic materials, accelerating curing and improving the overall performance of the coating.

[0030] Compared with the prior art, the present invention has the following beneficial effects: (1) The anti-slip coating provided by the present invention utilizes a dual curing mechanism. On the one hand, inorganic salts crystallize and cure at room temperature to form a hard and stable structure. On the other hand, metal organic acid salts catalyze the organic vinyl polymer to undergo oxidation and curing in air, imparting the coating with excellent flexibility and adhesion. This dual curing mechanism combines the advantages of inorganic and organic materials, not only accelerating the curing speed but also improving the overall performance of the coating, ensuring excellent durability and stability in complex environments.

[0031] (2) The present invention utilizes the free hydrogen atoms in the phosphate ester to react with the metal ions in the silicate to form a co-salt of phosphate and silicate. This reaction allows the metal ions to bind to both the organic phosphate and the inorganic silicate, thereby constructing a three-dimensional organic-inorganic interpenetrating network structure. This structure not only combines the flexibility of organic materials with the rigidity of inorganic materials, but also enhances the overall stability and mechanical properties of the material through the bridging effect of the metal ions.

[0032] (3) The present invention utilizes an alkali metal oxide solution to dually control the silicate modulus and the pH value of the emulsion, achieving good adhesion of the silicate after drying and forming a film while maintaining the stability of the emulsion, thus ensuring the excellent performance of the coating. By regulating the appropriate ratio of corundum and silicon carbide, the anti-slip coefficient of the coating is significantly improved.

[0033] (4) The dual-curing anti-slip coating prepared by the present invention has a low VOC content, improves environmental performance, and conforms to the development trend of modern coatings. DETAILED DESCRIPTION

[0060] Table 5 Performance test results of dual-curing anti-slip coating products of Examples 1 to 6

[0061] Table 6 Performance test results of coating products of Comparative Examples 1 to 4

[0062] As can be seen from Tables 5 and 6, the dual-cured anti-slip coating prepared by the present invention, after the inorganic silicate is dried and cured at room temperature to form a film and the organic vinyl oligomer is catalyzed and oxidized by a drying agent to form a film to form an inorganic / organic interpenetrating polymer network, has an anti-slip coefficient of up to 0.69, an adhesion of up to 11 MPa, and a salt spray resistance of up to 8000 hours. The performance is superior to the existing traditional zinc-rich anti-slip and anti-corrosion materials. Its low VOC content of only 10 g / L also improves the environmental friendliness of the anti-slip and anti-corrosion material.

[0063] The data from Comparative Example 2 and Examples 2-4 demonstrate that a reasonable ratio of corundum to silicon carbide can significantly improve the coating's anti-slip coefficient. The combination of corundum and silicon carbide creates a multi-scale rough surface, enhancing the mechanical interlocking effect at the contact surface and thus improving the coating's anti-slip performance. Because corundum has a slightly higher coefficient of friction than silicon carbide, a low proportion of corundum reduces the coating's friction coefficient and degrades its anti-slip performance.

[0064] The data from Comparative Example 3 show that when the coating formula is mainly composed of inorganic silicates, the coating has a low anti-slip coefficient. This is because the friction force is small after the inorganic silicates crystallize and solidify. In addition, the metal heteroatoms (such as potassium and sodium) in the inorganic silicates will form competitive adsorption with the zinc powder and the substrate surface, hindering the close chemical bonding between the zinc powder and the substrate, resulting in a weakened bonding between the coating and the substrate.

[0065] The data from Comparative Example 4 show that when the coating formula is mainly based on organic vinyl oligomers, the coating has a high anti-slip coefficient. However, since zinc powder has poor dispersibility in the organic vinyl oligomer water-based coating system and is easily aggregated, the coating becomes uneven inside, the porosity increases, the adhesion decreases, and it is difficult to effectively block the penetration of chloride ions, thereby weakening the salt spray resistance.

[0066] It should be noted that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments are merely examples, and any embodiments having substantially the same structure and effect as the technical concept within the scope of the technical solution of the present invention are all included in the technical scope of the present invention. In addition, without departing from the scope of the present invention, other embodiments that can be conceived by those skilled in the art and that combine some of the constituent elements in the embodiments are also included in the scope of the present invention.
