Description

Technical Field

[0001] The present invention relates to the technical field of super-hydrophobic coatings, and in particular to a super-hydrophobic anti-icing coating and a preparation method and application thereof. Background Art

[0002] At present, there are four main traditional anti-icing technologies. Electric heating anti-icing heats the surface of high-voltage transmission lines through electric heating elements to prevent frost and ice beads from gathering. Chinese patent CN112009694A discloses an electric heating coating anti-icing technology. By constructing a three-layer structure of a bottom electrode layer, an intermediate heating layer and a top electrode layer, it achieves the effect of anti-icing on a three-dimensional complex surface and improves the reliability of the system. However, this method requires the construction of a complex surface film layer structure, which is complex in process and difficult to implement on high-altitude transmission lines. It also consumes a lot of energy, resulting in a significant reduction in energy utilization. Chemical anti-icing sprays a deicing agent containing at least one alkali metal acetate or at least one alkaline earth metal acetate and a solvent as components onto the transmission cable to achieve the purpose of anti-icing and de-icing. Chinese patent CN102977942A discloses a liquid anti-icing agent with a formula of diethylene glycol methyl ether, an antioxidant, a preservative and an anti-wear agent, which generates heat on the surface by self-heating to increase the temperature to achieve an anti-icing effect, but it will cause irreversible pollution to the natural environment and it is difficult to achieve sustainable development requirements. Mechanical vibration anti-icing, Chinese patent CN118499205 discloses a mechanical vibration anti-icing technology based on ultrasound, which can generate small vibrations on the application surface without affecting the aerodynamic characteristics, and achieve rapid rebound, splashing and expulsion of supercooled liquid to complete the anti-icing operation, but it often takes a long time to complete the deicing task, and the efficiency is low. Coating anti-icing method, Chinese patent CN111548730 discloses a composite photosensitive pigment and resin coating composite resistance thermal effect to achieve the anti-icing effect, but the coating itself still faces problems such as insufficient durability and poor weather resistance.

[0003] In addition, the equipment and material costs of traditional anti-icing technology are also high, which increases the burden of use and maintenance. In summary, the existing anti-icing technology has several problems: low energy utilization and efficiency; environmental pollution; complex preparation process, difficult to implement on high-voltage transmission cables; high cost.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a super-hydrophobic anti-icing coating and a preparation method and application thereof, aiming to solve the problems of low energy utilization, complex preparation process and high cost in the existing anti-icing technology.

[0006] The technical solution of the present invention is as follows:

[0007] A super-hydrophobic anti-icing coating is prepared by comprising the following components by weight: 80-120 parts of resin materials, 20-35 parts of nano materials, 300-500 parts of solvents, and 20-35 parts of high-molecular saturated hydrocarbon micron particles or 45-55 parts of siloxane materials.

[0011] The super-hydrophobic anti-icing coating, wherein the solvent includes one or more of toluene, tetrahydrofuran, n-heptane, n-hexane, carbon tetrachloride, chloroform, ethyl acetate, and tannin.

[0012] The super-hydrophobic anti-icing coating comprises, by mass, 100 parts of resin material, 25 parts of nanomaterial, 400 parts of solvent, and 25 parts of high molecular weight saturated hydrocarbon micron particles.

[0013] The super-hydrophobic anti-icing coating comprises, by mass, 100 parts of resin material, 25 parts of nanomaterial, 400 parts of solvent and 50 parts of siloxane material.

The present invention uses low surface energy resin materials, combined with micron-level and nano-level fillers to construct an anti-icing coating, and the roughness of the composite micro-nano structure is constructed on the basis of the low surface energy of the coating. The heat loss of the droplets is reduced by the insulating effect of the air cushion in the micro-nano structure, and the adhesion of ice is reduced, thereby achieving better ice-repelling and anti-icing effects; specifically, the combined effect of low surface energy and roughness is the key to achieving the hydrophobic performance of the material surface. When the surface energy of the material is lower than the surface tension of water, water droplets can be quickly driven away from the material surface, and the rough surface can provide a smaller contact area, increasing the difficulty of water droplets filling the gaps, thereby reducing the contact area of ​​water so that it can be quickly driven away from the material surface; and the provided super-hydrophobic anti-icing coating has a resin composite micro-nano structure, which realizes a strong interaction between the resin material and the micro-nano particles and the metal substrate, and constructs a strong binding force anti-icing surface on the transmission line, which can make the droplets splash and drive away quickly on the cable surface in a low temperature environment, achieving a high-efficiency anti-icing effect, and the super-hydrophobic anti-icing coating material has excellent durability and reduces operation and maintenance costs; by simplifying the coating formula and using green coating materials, environmental protection requirements are achieved and material costs are reduced. At the same time, the stability and durability of the super-hydrophobic anti-icing coating are improved through composite resins and micro-nano structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention provides a super-hydrophobic anti-icing coating and a preparation method and application thereof. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as generally understood by those skilled in the art in the art to which the present invention belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have meanings consistent with the meanings in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as herein.

[0030] High-voltage power transmission meets the need to transmit electricity over long distances in densely populated cities and industrial areas, achieves a balanced allocation of power resources, avoids the contradiction between supply and demand caused by uneven energy distribution, and can efficiently deliver clean energy to cities and industrial areas through high-voltage power transmission, promote the development and utilization of new energy, reduce dependence on traditional energy, and promote sustainable development. However, continued low temperatures and freezing rain weather can seriously cause ice on transmission lines, increase cable weight and wind resistance, and cause accidents such as line breaks and tower collapses. Ice can also cause flashover failures, affect the stable operation of the power system, cause serious inconvenience to residents' lives and industrial production, and even cause large-scale power outages. In addition, ice can also aggravate line corrosion, shorten equipment life, and make maintenance difficult, increasing the cost of power grid operation and maintenance and safety hazards.

[0031] Chinese patent CN118374195 provides a nano super-hydrophobic anti-icing coating, which has a low surface energy and a special rough structure, reducing the adhesion of ice to the coating. However, the super-hydrophobic anti-icing coating technology still has problems such as complex formulation and process, short coating life, poor stability and environmental unfriendliness, making it difficult to use on high-voltage cable transmission lines that have been put into operation.

[0032] Based on this, the present invention provides a super hydrophobic anti-icing coating, which is prepared by including the following components by mass: 80-120 parts of resin materials, 20-35 parts of nanomaterials, 300-500 parts of solvents, and 20-35 parts of high molecular weight saturated hydrocarbon micron particles or 45-55 parts of siloxane materials.

[0033] In this embodiment, the provided super-hydrophobic anti-icing coating has a resin composite micro-nano structure, which realizes a strong interaction between the resin material and the micro-nano particles and the metal substrate, and constructs a strong binding force anti-icing surface on the transmission line, which can make the droplets splash and drive away quickly on the cable surface in a low temperature environment, achieving a high-efficiency anti-icing effect, and the super-hydrophobic anti-icing coating material has excellent durability and reduces operation and maintenance costs; by simplifying the coating formula and using green coating materials, environmental protection requirements are achieved and material costs are reduced. At the same time, the stability and durability of the super-hydrophobic anti-icing coating are improved by composite resin and micro-nano structure.

[0034] Specifically, the addition of resin materials enhances the bonding force and interaction between the coating and the substrate, effectively providing the stability and durability of the coating; high molecular weight saturated hydrocarbon microparticles, siloxane materials and nanomaterials are mainly used to construct the micro-nano structure of the coating surface, forming an "air cushion" super-hydrophobic structure (such as the Cassie-Baxter model) of the composite wetting model. Figure 1 As shown), water droplets are quickly driven off and slide off the coating surface, achieving super self-cleaning and super anti-icing; the present invention utilizes a resin composite micro-nano structure to construct a coating surface, which comprehensively exhibits excellent super-hydrophobic and anti-icing properties, and reduces the heat loss of droplets through the insulation effect of the "air cushion" super-hydrophobic structure, thereby solving the low-temperature cracking problem of traditional resin coatings and achieving a highly efficient anti-icing effect; and the solvent is mainly used to dissolve resin materials and disperse particles.

[0035] In some embodiments, the resin material includes, but is not limited to, one or more of fluorosilicone resin, fluorocarbon resin, epoxy resin, polyester resin, and acrylic resin. The addition of the above resin materials is conducive to enhancing the bonding force and interaction between the coating and the substrate, and effectively provides the stability and durability of the coating.

[0036] In some embodiments, the nanomaterials include, but are not limited to, stearic acid, diatomaceous earth, nano-hydrophobic silica, nano-hydrophobic titanium dioxide, nano-hydrophobic zinc oxide, nano-hydrophobic cellulose, nano-cellulose crystals, and one or more of the hydrophilic particles of stearic acid, diatomaceous earth, nano-hydrophobic silica, nano-hydrophobic titanium dioxide, nano-hydrophobic zinc oxide, nano-hydrophobic cellulose and nano-cellulose crystals that have been silanized or grafted and modified. The above nanomaterials can be mixed with high molecular weight saturated hydrocarbon micron particles or siloxane materials to construct a micro-nano structure on the surface of the coating, forming an "air cushion" super-hydrophobic structure of a composite wetting model, so that water droplets can be quickly driven away and slide off the surface of the coating, achieving super self-cleaning and super anti-icing.

[0037] Specifically, the nanomaterials include hydrophilic particles of stearic acid, diatomaceous earth, nano-hydrophobic silicon dioxide, nano-hydrophobic titanium dioxide, nano-hydrophobic zinc oxide, nano-hydrophobic cellulose, and nano-cellulose crystals treated by silanization, grafting, etc., which can also be mixed with high molecular saturated hydrocarbon micron particles or siloxane materials to construct a micro-nano structure on the coating surface. Among them, the nano-hydrophobic cellulose is spherical or quasi-spherical; the nano-cellulose crystals are fibrous.

[0038] In some embodiments, the material of the polymer saturated hydrocarbon microparticles includes but is not limited to one or more of polytetrafluoroethylene, polyperfluoroethylene propylene, fluorinated ethylene-propylene copolymer, and chlorinated polyethylene; the siloxane materials include but are not limited to one or more of polydimethylsiloxane, ethylsiloxane, propylsiloxane, amino-modified siloxane, cyclosiloxane (such as cyclotetrasiloxane, etc.), and halogenated siloxane. The above-mentioned polymer saturated hydrocarbon microparticles or siloxane materials are used together with nanomaterials as raw materials for super-hydrophobic anti-icing coatings to construct micro-nano structures on the surface of the coating, forming a "air cushion" super-hydrophobic structure of a composite wetting model, so that water droplets can be quickly driven away and slide off the surface of the coating, achieving super self-cleaning and super anti-icing.

[0039] In some embodiments, the solvent includes but is not limited to one or more of toluene, tetrahydrofuran, n-heptane, n-hexane, carbon tetrachloride, chloroform, ethyl acetate, and tannin. The above solvents are mainly used to dissolve resin materials and disperse particles, so that the resin materials, nanomaterials, and high molecular weight saturated hydrocarbon microparticles or siloxane materials are evenly mixed.

[0040] In some embodiments, the super hydrophobic anti-icing coating is prepared by comprising the following components by weight: 100 parts of resin material, 25 parts of nanomaterial, 400 parts of solvent, and 25 parts of high molecular weight saturated hydrocarbon micron particles.

[0041] In some embodiments, the super hydrophobic anti-icing coating is prepared by comprising the following components by weight: 100 parts of resin material, 25 parts of nano material, 400 parts of solvent, and 50 parts of siloxane material.

[0042] Specifically, after the raw materials of the super-hydrophobic anti-icing coating are mixed according to the above mass fractions, a coating structure with strong hydrophobicity and anti-icing can be obtained; the super-hydrophobic anti-icing technology uses the characteristics of the super-hydrophobic surface, such as a water contact angle greater than 150° and a water rolling angle less than 10°, so that raindrops can quickly detach from the surface, thereby showing excellent anti-icing potential. In addition, the super-hydrophobic surface can also achieve self-repairing performance and long service life, can maintain the anti-icing effect in various environments, improve anti-icing efficiency, and reduce operation and maintenance costs.

[0043] In addition, Figure 2 As shown, the present invention also provides a method for preparing a super-hydrophobic anti-icing coating, comprising the steps of:

[0044] Step S10: mixing the resin material with the solvent to obtain a mixed solution;

[0045] Step S20: mixing the mixed solution with nanomaterials, and high molecular weight saturated hydrocarbon micron particles or siloxane materials to obtain a coating dispersion;

[0046] Step S30: spraying the coating dispersion onto the substrate using a spray gun to obtain a super-hydrophobic anti-icing coating precursor;

[0047] Step S40: After the super-hydrophobic anti-icing coating precursor is cured, a super-hydrophobic anti-icing coating is obtained.

[0048] In this embodiment, the production cost of the superhydrophobic anti-icing coating is reduced by simplifying the formula and preparation method; the "one-step method" is used to simplify the preparation method, and it can be applied to high-altitude high-voltage transmission cables by high-altitude drone spraying and other methods. The process is simple and easy to operate, and a continuous and effective anti-icing coating is formed on the surface of the substrate, which solves the drawbacks of traditional anti-icing technology, improves the anti-icing efficiency of high-voltage transmission cables, and thus ensures the safety of the operation of the power grid system.

[0049] In some embodiments, the distance between the spray gun nozzle and the substrate is 5 cm to 8 cm. By controlling the distance between the spray gun nozzle and the substrate within the above range, the thickness of the super-hydrophobic anti-icing coating can be controlled and the coating thickness can be uniform without defects and the curing rate will not be too fast.

[0050] In some embodiments, the diameter of the spray gun nozzle is 1 mm-3 mm; preferably, the diameter of the spray gun nozzle is 1 mm.

[0051] In some embodiments, the curing of step S30 is specifically as follows: the curing temperature is 60° C.-80° C., and the curing time is 6 h-9 h; under the curing conditions, the coating dispersion can be cured to form a super-hydrophobic anti-icing coating.

[0052] In some embodiments, the super hydrophobic anti-icing coating has a thickness of 8-10 μm.

[0053] In addition, the present invention also provides an application of a super-hydrophobic anti-icing coating in a high-voltage transmission cable.

[0054] In this embodiment, the super-hydrophobic anti-icing coating is used in high-voltage transmission cables, which can solve the low-temperature cracking problem of traditional resin coatings and effectively reduce the amount of icing on aluminum strands. At the same time, compared with existing super-hydrophobic anti-icing coatings, the super-hydrophobic anti-icing coating of the present invention has a simple and efficient formula and does not produce secondary pollution. The one-step spraying method is simple and easy, low-cost and high-efficiency, and can be used for large-scale drone spraying of high-altitude cables.

[0055] Specifically, the super-hydrophobic anti-icing coating provided by the present invention can be applied to the resin composite micro-nano structure super-hydrophobic coating of the aluminum stranded wire of the high-voltage transmission cable. The formula is simple and environmentally friendly. The one-step spraying method is used for the preparation process with a short flow and simple process, and the icing effect is excellent. It can be directly applied to the anti-icing treatment of the aluminum stranded wire of the high-voltage transmission cable put into use.

[0056] The following examples are further given to illustrate the present invention in detail. It should also be understood that the following examples are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Some non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention belong to the scope of protection of the present invention.

[0057] Example 1

[0058] By mass, 100 parts of fluorosilicone resin were dissolved in 400 parts of tetrahydrofuran, and 25 parts of hydrophobic fumed silica and 25 parts of polytetrafluoroethylene powder were added and ultrasonically dispersed until uniform. The coating dispersion was placed in a spray gun with a nozzle diameter of 1 mm and a distance of 6 cm between the spray gun nozzle and the aluminum stranded wire and the test aluminum plate substrate to ensure that the coating was uniform and defect-free and that the curing rate was not too fast. The coating was cured by forced air drying at 60°C for 8 hours to obtain a high-voltage cable aluminum stranded wire with a coating layer and a test aluminum plate with a coating layer.

[0059] The test aluminum plate with the coating layer in this example is used to characterize the hydrophobicity of the coating layer by water contact angle. Figure 3 As shown in Figure 1, a water contact angle of 149.67° is achieved, so that water droplets are quickly driven off the coating and do not adhere. Figure 4As shown, a rough structure with micro-nano level is formed to achieve a hydrophobic effect on the coating surface.

[0060] Example 2

[0061] By mass, 100 parts of phenolic resin were dissolved in 400 parts of tetrahydrofuran, and 25 parts of hydrophobic fumed silica and 50 parts of amino-modified siloxane were added and ultrasonically dispersed until uniform. The coating dispersion was placed in a spray gun with a nozzle diameter of 1 mm, and the spray gun nozzle was evenly sprayed 6 cm away from the aluminum stranded wire and the test aluminum plate substrate to ensure that the coating was uniform and defect-free, and the curing rate was not too fast. The coating was cured by forced air drying at 60°C for 8 hours to obtain a coated high-voltage cable aluminum stranded wire and a coated test aluminum plate.

[0062] The test aluminum plate with the coating layer in this example is used to characterize the hydrophobicity of the coating layer by water contact angle. Figure 5 As shown in Figure 1, a water contact angle of 144.26° is achieved, so that water droplets are quickly driven off the coating and do not adhere. Figure 6 As shown, a rough structure with micro-nano level is formed to achieve a hydrophobic effect on the coating surface.

[0065] 2) Place the sample at an angle in a -10℃ programmable constant temperature box for 1 hour, with the angle between the sample and the horizontal plane being 35±2 degrees;

[0066] 3) Use the same adjusted spray pot to spray water droplets to the samples in turn. Spray each sample once. The spraying interval is about 1s. Spray all samples once as one round. Stop spraying for 15 minutes after every 10 rounds.

[0067] 4) After repeating step 3) three times, use a balance to measure the mass of each ice-covered sample and calculate the ice-covered weight.
