Description

Technical Field

[0001] This application relates to the technical field of protecting new materials, and particularly to a new surface protection material for armored vehicles. Background Art

[0002] A substrate coated with an anti-sticking coating having friction resistance, wherein the ratio of the thickness of the coating to the longest diameter of the said ceramic particles is 0.8 to 2.0. Another substrate coated with an anti-sticking coating having friction resistance, the coating comprising a bottom coating and a top coating, and the ratio of the total thickness of the bottom coating and the top coating to the longest diameter of the ceramic particles is 0.8 to 2.0. There is also provided a composition capable of forming an adherent coating on a smooth substrate and exhibiting abrasion resistance, wherein the amount of ceramic particles is sufficient to provide at least 3 such particles per 1 cm length of cross-section of the coating formed from the said composition.

[0003] Currently, the preparation process of high-toughness wear-resistant TPU composites is also an increasingly mature technology, which is used to solve the problems of poor toughness and wear resistance of traditional TPU materials, restricting their application scope; the diol monomer of this preparation process is fluorinated diol, and the molecular structure of fluorinated diol contains an indole structure, with high stability, and contains a large number of fluorine atoms. Fluorine atoms have a small atomic radius and high electronegativity, which enables fluorine atoms to form tight and stable chemical bonds in the resin molecules. This stable chemical bond structure makes the prepared TPU have a relatively high surface hardness, and its self-lubricity is particularly good, which enables it to resist the friction and wear of external objects, making it have excellent wear resistance. Then, carbon fibers are added to form TPU composites, improving the toughness of TPU composites and further enhancing their wear resistance.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: existing new protection materials generally have the disadvantages of poor wear resistance and poor corrosion resistance. Generally, they are epoxy ceramic materials, which are made by high-temperature processing and used as wear-resistant protective layers for equipment.

[0017] By adopting the above technical solutions, a variety of high-performance inorganic and organic composite materials are used. Through a unique ratio and preparation process, the protection performance of the armored vehicle surface is significantly improved. By adding inorganic components such as phosphates, silica powder, zirconia, zinc oxide, aluminum sulfate, and silicon nitride, the heat resistance, corrosion resistance, wear resistance, and impact resistance of the material are enhanced, which can effectively protect the armored vehicle surface from the erosion of high temperature, acid-base, salt spray, and other harsh environments. Components such as nano-metal ceramics and zirconia in the material can enhance the hardness and scratch resistance of the material, thereby increasing the protection ability of the armored vehicle and resisting physical impact. The addition of silane coupling agent and acidic silica sol helps to improve the adhesion between the material and the armored vehicle matrix, ensuring the stability and durability of the protective layer. The use of organic components such as dispersants, curing agents, and deionized water enables the components in the formula to be evenly dispersed, further enhancing the application performance of the material. In addition, through specific heating and curing processes, the high temperature resistance and structural stability of the protective layer are ensured, so that the material can continuously play a role in extreme environments, significantly extending the service life of the armored vehicle, improving the combat efficiency, making the new material for armored vehicle surface protection have good corrosion resistance, high temperature resistance, wear resistance, impact resistance, and excellent adhesion, effectively enhancing the protection performance of the armored vehicle, extending the service life, and reducing the maintenance cost.

[0018] Optionally, the annealing treatment of the new protection material can promote the diffusion of elements in the coating, homogenize the structure and composition of the new material, and avoid the holes and cracks generated in the coating during the preparation process. When annealing, heating starts when the vacuum degree is lower than 5.0×10 – 2 Pa, the heating rate is 3℃ / min, keep it at 600℃ for 5h and then cool it to room temperature with the furnace. The isothermal oxidation test is carried out in a muffle furnace at 800℃, and the oxidation time is 200h.

[0019] By adopting the above technical solutions, it can effectively promote the diffusion and homogenization of elements in the coating, optimize the organizational structure of the coating, eliminate the holes and cracks that may be generated during the preparation process, significantly improve the density and integrity of the coating, and enhance its oxidation resistance and high temperature resistance. Annealing treatment is carried out in a vacuum environment to ensure a low heating rate and precise temperature control, which helps to evenly distribute the components in the material and avoid coating deformation or structural instability caused by rapid heating. The isothermal oxidation test of the coating at 800℃ after annealing further verifies its oxidation resistance at high temperature, ensuring that the coating can remain stable for a long time in a high temperature environment without oxidation or damage, thereby enhancing the reliability and durability of the protective coating in practical applications, effectively enhancing the high temperature oxidation resistance and mechanical strength of the new material, and improving the comprehensive protection effect of the armored vehicle surface protective layer.

[0020] Optionally, elements such as Pt and C are introduced into the coating for composition modification, effectively improving both the oxidation resistance of the coating and the spallation resistance of the oxide film.

[0021] By adopting the above technical solution, introducing elements such as Pt and C into the coating for composition modification can significantly improve the oxidation resistance of the coating, enhance the stability and durability of the oxide film, prevent the oxide film from spalling under high-temperature environments, thereby improving the long-term use performance of the coating under extreme conditions, and ensuring effective protection of the armored vehicle surface in high-temperature and oxidation environments.

[0022] Optionally, a multi-arc ion plating device is used to prepare wear-resistant new materials at oxygen flow rates of 2, 12 sccm, and 22 sccm respectively. After high-temperature processing at 800 °C for 200 h, protective new materials are formed on the surface, and the oxide film thicknesses are 6 μm, 7 μm, and 5 μm respectively.

[0023] By adopting the above technical solution, using a multi-arc ion plating device to prepare wear-resistant new materials at different oxygen flow rates can effectively control the thickness and uniformity of the oxide film, enabling it to form a stable protective coating under high-temperature environments, thereby improving the wear resistance, oxidation resistance, and high-temperature stability of the coating, and ensuring that the material maintains excellent protective effects under long-term high-temperature conditions.

[0024] Optionally, obvious stratification occurs in the oxide film of the new materials with oxygen flow rates of 2 and 12 sccm. The upper layer is stannous octoate, and the lower layer is epoxy resin. However, the oxide film of the coating with a flow rate of 22 sccm does not stratify and plays a protective role.

[0025] By adopting the above technical solution, by adjusting the oxygen flow rate to 2 and 12 sccm, an obvious stratified structure can be formed in the oxide film of the new material. The upper layer is stannous octoate, and the lower layer is epoxy resin. The stratified structure can effectively enhance the oxidation resistance and wear resistance of the coating, while improving the stability and durability of the coating under high-temperature environments; at an oxygen flow rate of 22 sccm, the oxide film of the coating does not stratify, but still forms a dense protective layer, effectively avoiding coating peeling and oxidation, and ensuring the long-term high-temperature protection performance of the material. This technical solution optimizes the oxygen flow rate to control the oxide film structure and enhances the comprehensive protection function of the new material.

[0026] Optionally, the dosage ratios of sodium acetate, stannous octoate, stannous octoate, acidic silica sol, N, silane coupling agent, and nano-metal ceramic material in step S2 are 15 - 20 mmol : 0.5 - 0.7 g : 40 - 45 mL : 15 mmol : 2 - 5 mL : 20 - 30 mmol.

[0027] By adopting the above technical solution, by precisely controlling the dosage ratios of the components in step S2, the reaction formula can be optimized to ensure the uniformity of the distribution of sodium acetate, stannous octoate, acidic silica sol, silane coupling agent, and nano metal ceramic material in the material and the high efficiency of the chemical reaction, thereby enhancing the adhesion, corrosion resistance, and oxidation resistance of the coating. This ratio helps to form a stable composite coating, improve the anti-wear, anti-impact, and high-temperature resistance of the material, and through reasonable reactions and material combinations, the overall protection effect of the coating is enhanced, and the long-term protection ability of the armored vehicle surface in harsh environments is strengthened.

[0028] Optionally, the dosage ratios of the curing agent and the dispersant in step S3 are 10 mmol: 60 - 70 mL: 50 - 70 mmol, the mass fraction of sodium acetate is 30 - 40%, and the particle size of the nano metal ceramic material is 100 - 150 mesh.

[0029] By adopting the above technical solution, by precisely controlling the dosage ratios of the curing agent and the dispersant in step S3, as well as the mass fraction of sodium acetate and the particle size of the nano metal ceramic material, the reactivity, dispersibility, and curing effect of the coating can be optimized to ensure that the material has a uniform structure and excellent physical properties. The reasonable ratio of the curing agent to the dispersant helps to improve the stability and oxidation resistance of the coating, the appropriate mass fraction of sodium acetate improves the heat resistance and adhesion of the coating, and the precise control of the particle size of the nano metal ceramic material enhances the hardness, wear resistance, and impact resistance of the coating, ultimately enabling the coating to have a long-term stable protection function under high temperature and harsh environments.

[0030] Optionally, the dosage ratios of the silane coupling agent, the dispersant, the phosphate, and the toughening agent in step S1 are 15: 25 mmol: 60: 100 mL.

[0031] By adopting the above technical solution, precisely controlling the dosage ratios of the silane coupling agent, the dispersant, the phosphate, and the toughening agent in step S1 can optimize the dispersibility, adhesion, and toughness of the material, thereby enhancing the bonding force between the coating and the substrate, improving the corrosion resistance and oxidation resistance of the coating. The reasonable dosage of the silane coupling agent can improve the adhesion of the coating, the action of the dispersant makes the components evenly distributed, and the addition of the phosphate and the toughening agent helps to improve the hardness, impact resistance, and high-temperature resistance of the coating, while increasing the flexibility of the coating to avoid crack formation caused by thermal expansion differences.

[0032] Optionally, the dosage ratios of intermediate 5, 12% palladium on carbon, ethanol, and the silane coupling agent in step S5 are 15 mmol: 0.6 - 0.8 g: 60 - 70 mL: 10 - 30 mL, and the mass fraction of the silane coupling agent is 70%.

[0033] By adopting the above technical solutions, precisely controlling the dosage ratios of the intermediate, palladium-carbon, ethanol, and silane coupling agent in step S5, as well as the mass fraction of the silane coupling agent, can effectively optimize the reactivity, dispersibility, and adhesion of the coating, ensuring that the material forms a uniform, dense, and high-performance protective coating. The appropriate dosage of palladium-carbon can promote the catalytic reaction of the coating, improving its high-temperature resistance and oxidation resistance. The use of ethanol helps dissolve and disperse each component, ensuring uniform coating, while the silane coupling agent at a high mass fraction enhances the adhesion and stability of the coating to the substrate, improving the impact resistance, corrosion resistance, and long-term high-temperature protection ability of the coating.
