Description

Technical Field

[0001] This invention relates to the field of ceramic plate technology, specifically to a wear-resistant and impact-resistant ceramic plate and its preparation method. Background Technology

[0002] In industries characterized by heavy wear and tear, such as cement, steel, mining, lithium batteries, and metallurgy, equipment and components often face severe wear problems. For example, in areas like hoppers, bins, pipes, and elbows, the impact and friction of materials cause traditional metal components to wear out rapidly, affecting production efficiency and increasing maintenance costs. Therefore, these industries urgently need a type of liner with good wear resistance and the ability to withstand strong impacts over a long period of time to replace traditional metal liners.

[0003] Although ordinary ceramic materials possess a certain degree of wear resistance, they are brittle and lack impact resistance, making them prone to cracking under significant impact forces, thus limiting their application in high-intensity working conditions. Therefore, developing a ceramic plate that can effectively resist wear and withstand strong impacts has significant practical importance and application value. Summary of the Invention

[0004] The purpose of this invention is to provide a wear-resistant and impact-resistant ceramic plate and its preparation method, so as to solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wear-resistant and impact-resistant ceramic plate, wherein the wear-resistant and impact-resistant ceramic plate is made by modifying a ceramic plate with a novel silane coupling agent, coating a modified epoxy resin adhesive onto a transparent vulcanized rubber plate, and pressing the two together under ultraviolet light irradiation.

[0006] The novel silane coupling agent is prepared by the addition reaction of allyl dimethoxysilane and acetylene;

[0007] The modified epoxy resin adhesive is prepared by adding 9-mercaptononanoic acid to the epoxy resin adhesive.

[0008] Furthermore, the ceramic plate is one of alumina ceramic plate, titanium boride ceramic plate, or aluminum nitride ceramic plate, and its thickness is 0.5 to 10 cm.

[0009] Furthermore, the epoxy resin adhesive is one of 618 epoxy resin adhesive, 828 epoxy resin adhesive, or DP190 epoxy resin adhesive.

[0010] Furthermore, the transparent vulcanized rubber sheet is prepared by mixing, open milling, calendering, and vulcanizing 100 parts of cis-butadiene rubber, 4 parts of dimercaptosuccinic acid, 20 parts of silica, 5 parts of zinc carbonate, 3 parts of triethanolamine, 4 parts of polyethylene glycol, 2 parts of Si69, 3 parts of 2,6-di-tert-butyl-4-methylphenol, and 8 parts of dicumyl peroxide in a weight ratio to obtain a transparent vulcanized rubber sheet with a light transmittance of 60-70%.

[0011] Furthermore, a method for preparing a wear-resistant and impact-resistant ceramic plate includes the following preparation steps:

[0012] (1) Add platinum catalyst to toluene, with a platinum concentration of 27–32 ppm in the reaction system. Then add polymethylvinylsiloxane with a molecular weight of 5000–10000, which is 11.0–11.5 times the mass of the platinum catalyst. Heat to 75–85 °C and stir at 200–300 r / min for 10 min. Purge with purified and dry acetylene gas and activate for 25–30 min. Then add allyl dimethoxysilane dropwise at a rate of 5.0–6.5 mL / h, with a molar ratio of platinum catalyst to allyl dimethoxysilane of 1.2 × 10⁻⁶. -4 1. After being mixed with acetylene gas, the mixture is introduced into a reactor through a bubbler and reacted for 3 hours. The filtrate is then filtered, and the solvent is removed by vacuum distillation to obtain a novel silane coupling agent.

[0013] (2) Place the surface-activated ceramic plate in a silane coupling agent solution, heat it to 60-70℃, soak it for 1.5-2 hours, take it out, let it air dry naturally, wash it with ethanol 1-2 times, and dry it to obtain the modified ceramic plate.

[0014] (3) Apply the modified epoxy resin evenly to the transparent vulcanized rubber sheet, with a coating amount of 20-100 g / m². 2 The two materials are pressed together, irradiated under ultraviolet light for 3-5 minutes, and then pressed and cured for 24 hours to obtain a wear-resistant and impact-resistant ceramic plate.

[0015] Furthermore, in step (1), the platinum catalyst is chloroplatinic acid, and the flow rate of acetylene gas is 30-40 mL / min.

[0016] Furthermore, the surface-activated ceramic plate in step (2) is prepared by placing the ceramic plate in acetone and ultrasonically vibrating it for 15-20 minutes, drying it, placing it in a muffle furnace for oxygen oxidation etching, holding it at a temperature of 750°C, a heating rate of 10°C / min, a holding time of 2 hours, washing it with deionized water 2-3 times, and drying it.

[0017] Furthermore, in step (2), the silane coupling agent solution is prepared by mixing isopropanol and deionized water at a volume ratio of 8 to 10:1 to obtain an aqueous solution of alcohol, adding 0.15 to 0.20 times the volume of the aqueous solution of alcohol to a novel silane coupling agent, and stirring at 300 to 400 r / min for 10 to 15 min.

[0018] Furthermore, in step (3), the modified epoxy resin adhesive is prepared by mixing 9-mercaptononanoic acid and benzophenone at a mass ratio of 1:0.03 to 0.04, stirring at 100 to 150 r / min for 3 to 5 min to obtain a mixture, adding the mixture to 2 to 3 times the mass of epoxy resin adhesive, and stirring until the mixture is uniform.

[0019] Furthermore, the wavelength of the ultraviolet light in step (3) is 365nm.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0021] This invention first utilizes the addition reaction of allyl dimethoxysilane and acetylene to prepare a novel silane coupling agent, which is then uniformly coated on the surface of a ceramic plate. Modified epoxy resin is then coated onto a vulcanized transparent rubber plate. Under ultraviolet light irradiation, the ceramic plate and the vulcanized transparent rubber plate are pressed together to obtain a wear-resistant and impact-resistant ceramic plate, thereby achieving wear resistance and impact resistance.

[0022] First, a novel silane coupling agent was prepared by the addition reaction of allyl dimethoxysilane and acetylene. The novel silane coupling agent can introduce carbon-carbon double bonds into the ceramic surface. The novel silane coupling agent has two carbon-carbon double bonds in its structure, which introduces more double bonds into the ceramic plate surface. These double bonds can undergo click reactions with mercapto groups, providing more active sites for the reaction and thus accelerating the reaction rate.

[0023] Secondly, a modified epoxy resin adhesive was prepared by adding 9-mercaptononanoic acid to the epoxy resin adhesive. First, a layer of modified epoxy resin adhesive was coated onto a vulcanized rubber sheet. Then, the vulcanized rubber and ceramic sheet were pressed together under ultraviolet light irradiation. After the modified epoxy resin adhesive cured, a wear-resistant and impact-resistant ceramic sheet was obtained. The addition of 9-mercaptononanoic acid to the epoxy resin adhesive introduced mercapto groups into the system, and 9-mercaptononanoic acid can also act as a curing agent for the epoxy resin adhesive. Under ultraviolet light assistance, the mercapto groups in the modified epoxy resin adhesive will undergo a click reaction with the double bonds on the surface of the ceramic sheet, making the bond between the vulcanized rubber and the ceramic sheet stronger. This effectively prevents the peeling of the rubber layer from the ceramic sheet during use and the formation of chemical bonds, significantly improving the interfacial bonding strength between the rubber and ceramic sheet. This allows for better stress transmission, and the impact energy can be better dispersed between the rubber and ceramic, further improving the impact resistance of the ceramic sheet.

[0051] Comparative Example 2

[0052] The difference between Comparative Example 2 and Example 2 lies in step (3). Step (3) is changed to: placing the alumina ceramic plate in a silane coupling agent solution, heating it to 65°C, soaking it for 1.7 hours, taking it out, air-drying it naturally, washing it twice with ethanol, and drying it to obtain the modified alumina ceramic plate; the remaining steps are the same as in Example 2.

[0057] Example of effect

[0058] Table 1 below shows the performance analysis results of the wear-resistant and impact-resistant ceramic plates of Examples 1 to 3 and Comparative Examples 1 to 4 of the present invention.

[0059] Table 1

[0060]

[0061]

[0062] A comparison of the experimental data from Example 2 and Comparative Example 1 reveals that the present invention utilizes the addition reaction of allyl dimethoxysilane and acetylene to prepare a novel silane coupling agent. This novel silane coupling agent can introduce carbon-carbon double bonds into the ceramic surface. The novel silane coupling agent has two carbon-carbon double bonds in its structure, introducing more double bonds onto the ceramic plate surface. These double bonds can undergo click reactions with thiol groups, providing more active sites for the reaction and thus accelerating the reaction rate. A comparison of the experimental data from Example 2 and Comparative Example 2 reveals that the present invention does not activate the ceramic plate, resulting in fewer active sites on the ceramic plate surface. The novel silane coupling agent is less likely to react with the surface, and thiol groups cannot be introduced, preventing subsequent reactions. Consequently, the ceramic plate exhibits poor wear resistance and impact resistance. A comparison of the experimental data from Example 2 and Comparative Example 3 reveals that the present invention prepares a modified epoxy resin by adding 9-mercaptononanoic acid to the epoxy resin adhesive. A layer of modified epoxy resin adhesive is first coated onto a vulcanized rubber plate, and then the vulcanized rubber plate is irradiated with ultraviolet light. A wear-resistant and impact-resistant ceramic plate is obtained by pressing an adhesive and a ceramic plate together and curing the modified epoxy resin adhesive. Adding 9-mercaptononanoic acid to the epoxy resin adhesive introduces mercapto groups into the system, and 9-mercaptononanoic acid can also act as a curing agent for the epoxy resin adhesive. Under ultraviolet light assistance, the mercapto groups in the modified epoxy resin adhesive undergo a click reaction with the double bonds on the surface of the ceramic plate, making the bond between the vulcanized rubber and the ceramic plate stronger. This effectively prevents the peeling of the rubber layer from the ceramic plate during use and the formation of chemical bonds, significantly improving the interfacial bonding strength between the rubber and the ceramic plate. This allows for better stress transmission, and the impact energy can be better dispersed between the rubber and the ceramic, further improving the impact resistance of the ceramic plate. A comparison of the experimental data from Example 2 and Comparative Example 4 shows that applying ultraviolet light in this invention excites the mercapto groups in the modified epoxy resin adhesive to undergo a click reaction with the double bonds on the surface of the ceramic plate, making the bond between the vulcanized rubber and the ceramic plate stronger and effectively improving the wear resistance and impact resistance of the ceramic plate.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
