Description

Technical Field

[0001] This invention relates to the field of building materials technology, specifically to a surface adhesion material for 410S stainless steel profiled roofing sheets, its preparation and application method. Background Technology

[0002] In recent years, the state has required industrial buildings to transform towards green and energy-saving practices, and photovoltaic (PV) systems have gradually been adopted in various smelting plants. The owner of the steelmaking project for the Zhenshi Green High-End Nickel-Chromium New Materials Intelligent Manufacturing Project plans to install a PV system on the roof structure of the steelmaking and smelting plant area, which places higher demands on the performance of the roofing materials.

[0003] 410S stainless steel profiled sheets are a commonly used roofing material with certain advantages, but some problems have also emerged during long-term use. For example, their insufficient wear resistance, corrosion resistance, and heat resistance result in a shorter roof lifespan, requiring frequent replacement and increasing maintenance costs and the economic burden on enterprises. Existing roofing materials also have limitations in terms of aesthetics, failing to meet the appearance requirements of modern industrial buildings.

[0004] Therefore, developing a special adhesive material that can improve the wear resistance, corrosion resistance, and heat resistance of 410S stainless steel profiled sheets for roofing, while also having an aesthetic effect, is of great practical significance. Summary of the Invention

[0005] The purpose of this invention is to provide a surface adhesion material for 410S stainless steel profiled roofing sheets, its preparation, and its application method. This material can further enhance the wear resistance, corrosion resistance, and heat resistance of the 410S stainless steel profiled roofing sheets, making their service life longer. This invention also provides a method for preparing this special adhesion material and a method for applying it to the surface of 410S stainless steel profiled roofing sheets.

[0006] 1. Composition of special adhesion materials

[0007] By weight, the special adhesion material of the present invention comprises the following components:

[0008] 30-50 parts of silicone resin: Silicone resin has good heat resistance, water resistance and weather resistance, and can provide basic protection for profiled sheets.

[0009] 20-30 parts of fluorocarbon resin: Fluorocarbon resin has excellent corrosion resistance and UV resistance, which can further enhance the protective ability of the profiled sheet.

[0010] 5-10 parts of nano titanium dioxide: Nano titanium dioxide has photocatalytic activity and ultraviolet shielding effect, which can improve the self-cleaning ability and ultraviolet resistance of materials.

[0011] 3-8 parts of nano zinc oxide: Nano zinc oxide has antibacterial, anti-ultraviolet and wave-absorbing properties, which help improve the overall performance of materials.

[0012] 10-20 parts of wear-resistant filler: Wear-resistant filler can increase the hardness and wear resistance of materials, and can be selected from one or more of silicon carbide, alumina or quartz sand.

[0013] Additives 2-5 parts: Additives include dispersants, defoamers, and leveling agents, which are used to improve the processing performance of materials and coating quality.

[0014] Solvent 15-30 parts: The solvent is used to dissolve the resin and other components, giving the material good flowability and workability.

[0015] 2. Preparation method of special adhesion materials

[0016] Organosilicon resin and fluorocarbon resin are added to a solvent and stirred evenly at 40-60℃ to obtain a mixed resin solution. This temperature range facilitates the dissolution and mixing of the resins, improving the homogeneity of the solution.

[0017] Nano-titanium dioxide, nano-zinc oxide, and wear-resistant filler are added sequentially to the mixed resin solution, and the mixture is stirred at high speed at 60-80℃ for 1-2 hours. High temperature and high-speed stirring ensure that the nanoparticles are fully dispersed in the resin solution, preventing agglomeration.

[0018] Add the additives and continue stirring for 30-60 minutes. Cool to room temperature to obtain the special adhesion material. The addition of additives can further improve the material's performance, and controlling the stirring time ensures that the additives can fully exert their effects.

[0019] 3. Surface treatment method for 410S stainless steel profiled sheets for roofing

[0020] The surface of the 410S stainless steel profiled sheet for the roof is cleaned, degreased, and derusted to remove impurities and oxides and improve the adhesion of special adhesive materials.

[0021] Special adhesion materials are evenly applied to the surface of the profiled sheet by spraying or brushing, with a coating thickness of 5-20 μm. Appropriate coating thickness ensures both the protective effect and aesthetic appeal of the material.

[0022] Curing at 80-120℃ for 1-2 hours allows the coating to fully cure and form a strong protective layer.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. Improved Abrasion Resistance: The addition of abrasion-resistant fillers effectively enhances the hardness of the special adhesive material, giving it stronger abrasion resistance and effectively resisting the abrasion effects of various external factors. Applying this high-strength, abrasion-resistant adhesive material to the surface of 410S stainless steel profiled sheets significantly extends the service life of the roofing 410S stainless steel profiled sheets, ensuring that they maintain good performance and stability during long-term use. Through this optimization treatment, the roofing material exhibits superior durability and reliability when facing complex environments and high-intensity usage conditions, thus providing longer-lasting and more reliable protection for the building.

[0025] 2. Enhanced Corrosion Resistance: The synergistic effect of silicone resin, fluorocarbon resin, and nanoparticles gives this adhesive material exceptional chemical corrosion resistance. This synergistic effect not only enhances the overall stability of the material but also effectively resists the erosion of various acids and alkalis. Whether it's a strong acid or a strong alkali, this material exhibits superior protective capabilities, ensuring the long-term stability and service life of 410S stainless steel profiled sheets in complex chemical environments.

[0026] 3. Enhanced Heat Resistance: As a high-performance material, silicone resin inherently possesses excellent heat resistance, maintaining stability at high temperatures. Building upon this, the introduction of nano-scale additives, nano-titanium dioxide and nano-zinc oxide, significantly improves the material's heat resistance. Nano-titanium dioxide, with its superior UV shielding ability and thermal stability, effectively enhances the material's high-temperature resistance; while nano-zinc oxide, with its good thermal conductivity and oxidation resistance, further optimizes the material's heat resistance. This ensures the performance of 410S profiled sheets in high-temperature environments, maintaining their original physical and chemical properties even under sustained high temperatures, guaranteeing their reliability and stability in various high-temperature applications.

[0027] 4. Excellent Aesthetics: The special adhesive material has flexible mixing characteristics, allowing for the creation of various colors to meet specific needs. This characteristic makes the 410S stainless steel profiled sheets used for the roof more visually appealing and elegant, enhancing the overall aesthetics of the building and fully meeting the high standards and stringent requirements of modern industrial buildings for appearance, ensuring that the building achieves the desired design effect.

[0028] 5. Energy Saving and Environmental Protection: The application of this adhesive material can significantly reduce the frequency of roof material replacement, thereby effectively reducing long-term maintenance costs. At the same time, it can also significantly improve the power generation efficiency of the photovoltaic system, ensuring maximum energy utilization. Through this innovative application method, the organic integration of the "industrial building and new energy" model has been successfully achieved, promoting the coordinated and high-quality development of both, and providing strong technical support and guarantee for the sustainable development of industrial buildings.

[0064] Example of surface treatment for 410S stainless steel profiled roofing sheets

[0065] Select several 410S stainless steel profiled roofing sheets and perform surface treatment according to the following steps:

[0066] 1. Clean the surface of the profiled sheet, sand it with sandpaper to remove the oxide layer, then clean it with acetone to remove oil, rinse it with water and let it dry.

[0067] 2. The special adhesion materials prepared in Examples 1-3 are uniformly adhered to the surface of the profiled sheet by spraying, and the coating thickness is controlled between 5-20 μm.

[0068] 3. Place the coated molding sheet in an oven and cure it at 80-120℃ for 1-2 hours.

[0069] Performance testing

[0070] Performance tests were conducted on the surface-treated 410S stainless steel profiled sheets for roofing. The test results are as follows:

[0071] Performance indicators Example 1 Example 2 Example 3 Abrasion resistance (wear loss, mg) 5 3 2 Corrosion resistance (salt spray test, h) 1000 1500 2000 Heat resistance (performance retention rate after high-temperature aging, %) 90 92 95

[0072] The test results show that the special adhesion material prepared by this invention can significantly improve the wear resistance, corrosion resistance and heat resistance of 410S stainless steel profiled sheets for roofing.

[0073] Furthermore, Figure ac shows a three-dimensional reconstruction of the wear tracks on the three samples. Color represents the height of the worn surface, with red areas indicating the highest point and blue areas indicating the lowest point. Therefore, the present invention... Figure 1 Color views were maintained to clearly show the differences in wear. The width and depth of the scratches on the 410S stainless steel substrate covered with 10μm and 20μm of adhering material were both narrower and shallower than those on the 410S substrate. This difference can be further confirmed by the two-dimensional profile curve in Figure d.

[0074] In addition, the coefficient of friction (COF) of the three samples was statistically analyzed, as shown in Figure e. The COF of the 410S stainless steel substrate covered with 10μm and 20μm of adhesive material was significantly lower than that of the 410S stainless steel substrate (0.6). However, the COF of the sample after surface coating fluctuated greatly, indicating that its wear behavior has a certain degree of instability.

[0075] Based on the wear volume calculations for each sample, the wear rates of 410S stainless steel profiled sheets with a 10μm thickness of adhesive material and those with a 20μm thickness of adhesive material were 3.6 × 10⁻⁶. -4 mm 3 ·N −1 ·m −1 8.6×10 -5 mm 3 ·N −1 ·m −1 and 6.2×10 -5 mm 3 ·N −1 ·m −1 As shown in Figure f, compared with 410S stainless steel profiled sheets, the wear rate of 410S stainless steel substrates covered with 10μm and 20μm thickness of adhesive material was reduced by 76% and 83%, respectively. This indicates that applying adhesive materials of 10μm and 20μm thickness to the surface of 410S stainless steel substrates can significantly improve the wear resistance of 410S stainless steel.

[0076] Figure 2 In this study, the geometric characteristics of the capacitive arc directly reflect the protective performance of the passivation film. A larger radius of the capacitive arc indicates greater difficulty in charge transfer, stronger resistance to corrosive ions, and better corrosion resistance. The annealed sample coated with a 20 μm thick layer of material exhibited a significantly increased capacitive arc radius, with the charge transfer resistance rising to 9498 Ω·cm. 2 Effectively hindered O 2- Cl - The interfacial charge transfer process. In contrast, the capacitive arc radius of the uncoated group was the smallest, and the charge transfer resistance decreased sharply to 936 Ω·cm. 2 O 2- Cl - The significantly increased penetration rate indicates that the coating material can effectively improve the corrosion resistance of 410S stainless steel profiled sheets.

[0077] from Figure 3 As can be seen, the oxidation weight gain of the heat-resistant sample without the coating material is significantly higher than that of the sample with the coating material content. Furthermore, the oxidation weight gain decreases significantly as the thickness of the coating material gradually increases. This indicates that the coating material can effectively form an oxide film, enhancing the stability of the 410S stainless steel profiled sheet. When the coating material thickness reaches 20 μm, the weight gain is lower than that of other samples throughout the entire time period, and the curve approximates a parabola. This indicates that this sample exhibits the best continuity and integrity of the oxide film, providing the best protection for the 410S stainless steel profiled sheet.

[0078] Industrial Applicability: The special adhesion material of this invention can be mass-produced industrially. Its preparation process is simple, raw materials are widely available, and costs are low. In industrial applications, this material can be widely used on the roofs of industrial buildings such as steelmaking and smelting plants, providing excellent protection for the 410S stainless steel profiled sheets, extending their service life, and reducing maintenance costs. The application of this material contributes to the coordinated and high-quality development of the "industrial building + new energy" model, possessing broad market prospects and good economic benefits.
