Description

Technical Field

[0001] The invention relates to the technical field of ceramic plates, in particular to a wear-resistant and impact-resistant ceramic plate and a preparation method thereof. Background Art

[0002] In heavy wear industries such as cement, steel, mining, lithium battery, and metallurgy, equipment and components often face serious wear problems. For example, in hoppers, silos, pipes, elbows, etc., the impact and friction of materials will cause rapid wear of traditional metal parts, affecting production efficiency and increasing maintenance costs. Therefore, these industries urgently need a liner with good wear resistance and the ability to withstand strong impact for a long time to replace the traditional metal liner.

[0003] Although common ceramic materials have certain wear resistance, they are brittle and have insufficient impact resistance. They are prone to breakage when subjected to large impact forces, which limits their application in high-intensity working conditions. Therefore, developing a ceramic plate that can effectively resist wear and withstand strong impact has important practical significance and application value. Summary of the invention

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

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a wear-resistant and impact-resistant ceramic plate, wherein the wear-resistant and impact-resistant ceramic plate is prepared by modifying a ceramic plate with a new silane coupling agent, coating a modified epoxy resin adhesive on a transparent vulcanized rubber plate, and pressing the two together under ultraviolet light;

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

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

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

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

[0010] Furthermore, the transparent vulcanized rubber plate is prepared by mixing 100 parts of butadiene rubber, 4 parts of dimercaptosuccinic acid, 20 parts of white carbon black, 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 diisopropylbenzene peroxide according to a weight ratio, performing internal mixing, open mixing, calendering and vulcanization to obtain a transparent vulcanized rubber plate, and the light transmittance is 60-70%.

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

[0012] (1) Add a platinum catalyst to toluene, wherein the concentration of platinum in the reaction system is 27 to 32 ppm, then add polymethylvinylsiloxane with a molecular weight of 5000 to 10000 in an amount of 11.0 to 11.5 times the mass of the platinum catalyst, heat to 75 to 85° C., stir at 200 to 300 r / min for 10 min, introduce purified and dried acetylene gas, activate for 25 to 30 min, then drop allyldimethoxysilane at a rate of 5.0 to 6.5 mL / h, and the molar ratio of the platinum catalyst to allyldimethoxysilane is 1.2*10 -4 : 1. After mixing with acetylene gas, the mixture enters the reactor through a bubbler and reacts for 3 hours. The filtrate is filtered and the solvent is removed by vacuum distillation to obtain a new silane coupling agent;

[0013] (2) placing the surface activated ceramic plate in a silane coupling agent solution, heating it to 60-70° C., soaking it for 1.5-2 hours, taking it out, drying it naturally in the shade, washing it with ethanol 1-2 times, and drying it to obtain a modified ceramic plate;

[0014] (3) Apply the modified epoxy resin glue evenly on the transparent vulcanized rubber plate, with a coating amount of 20 to 100 g / m 2 The two are pressed together, irradiated under ultraviolet light for 3 to 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 for ultrasonic vibration for 15 to 20 minutes, drying, placing the ceramic plate in a muffle furnace for oxygen oxidation etching, with a holding temperature of 750°C, a heating rate of 10°C / min, a holding time of 2 hours, washing with deionized water 2 to 3 times, and drying.

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

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

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

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

[0021] The present invention firstly utilizes the addition reaction of allyl dimethoxy silane and acetylene to prepare a new silane coupling agent, which is evenly applied on the surface of a ceramic plate, and a modified epoxy resin adhesive is coated on a vulcanized transparent rubber plate. The ceramic plate and the vulcanized transparent rubber plate are pressed together under ultraviolet light to obtain a wear-resistant and impact-resistant ceramic plate, so as to achieve wear-resistant and impact-resistant effects.

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

[0023] Secondly, 9-mercaptononanoic acid is added to the epoxy resin glue to prepare a modified epoxy resin glue, a layer of modified epoxy resin glue is first coated on the vulcanized rubber plate, and then the vulcanized rubber and the ceramic plate are pressed together under ultraviolet light, and the modified epoxy resin glue is cured to obtain a wear-resistant and impact-resistant ceramic plate; 9-mercaptononanoic acid is added to the epoxy resin glue to introduce a thiol group into the system, and 9-mercaptononanoic acid can also be used as a curing agent for the epoxy resin glue. Under the assistance of ultraviolet light, the thiol group in the modified epoxy resin glue will react with the double bonds on the surface of the ceramic plate to make the bond between the vulcanized rubber and the ceramic plate more firmly, effectively preventing the peeling of the rubber layer and the ceramic plate during use, and the formation of chemical bonds, so that the interface bonding strength between the rubber and the ceramic plate is significantly improved, which can better transmit stress, and the impact energy can be better dispersed between the rubber and the ceramic, further improving the impact resistance of the ceramic plate.
